FQXi Administrator Brendan Foster wrote on May. 24, 2012 @ 16:10 GMT
It is time once again for the FQXi Essay Contest! Past years, we have asked you to debate the
nature of time, what is
ultimately possible in physics, and whether reality is ultimately
digital or analog. This year we want to know:
Which of our basic physical assumptions are wrong?What assumptions are ripe for rethinking? Looking back over the history of physics we can identify a number of places where thinkers were "stuck" and had to let go of some cherished assumptions to make progress. Often this was forced by experiment, an internal inconsistency in accepted physics, or simply a particular philosophical intuition. What are the tacit or explicit assumptions we are making now that are ripe for re-thinking?
The contest is
open for entries starting now, and until 11:59 PM Eastern Time, August 31, 2012. Winners will be announced by December 7, 2012. The contest structure will be similar to previous years. Please read the rules and regulations carefully if you plan to enter. As always, the contest is open to everyone, regardless of background.
As in previous contests, we will post all official entries in our forums, which will open after we have received our first ten or so entries. Please join us in the forums to read, discuss, and vote whether you enter or not. And please help us spread the word.
We want to thank our partners and sponsors for helping us bring this contest to you. Much thanks to the
Peter and Patricia Gruber Foundation. And to
Submeta. Please take a moment to visit the sites of both these organizations, committed to advancing basic research in physics and other fields. And thanks to our media partner
Scientific American. When you need a break from reading essays, you'll find plenty more there to absorb you.
Please tell your colleagues and your friends. Happy writing, and happy reading!

What a pleasant surprise! I really like this topic, and I hope that a lot of people will participate (I certainly will). I think that this question is especially well suited to ask in relation to our understanding of what quantum mechanics means.
Briefly, I believe quantum mechanics is basically correct (i.e. I do not believe in hidden variables etc.), however understanding it properly may require us to modify some fundamental assumptions that at first seem only remotely related to the theory proper. In particular, I believe that our current notion of 'existence' is too crude in a somewhat similar way in which our understanding of 'time' pre-relativity turned out to be too crude.
Incidentally, there is a going to be a conference in Växjö, Sweden called Quantum Theory:Reconsideration of foundations-6, which takes place June 11th to June 15th, which seems closely related to this essay topic. As I understand it, attempts to identify assumptions which could be questioned and fresh ideas that could help us better understand how to interpret the mathematical formalism.
I look forward to the entries by the participants. Thanks fqxi for putting up the new contest.

Einstein's 1905 light postulate is certainly wrong but I am going to show that the second law of thermodynamics deserves no more credibility:
http://www.kostic.niu.edu/2ndLaw/2011SecondLaw-f
rontmatter.pdf
AIP Conference Proceedings, Volume 1411, Second Law of Thermodynamics: Status and Challenges, San Diego, California, USA 14-15 June 2011: "No physical principle holds greater sway in the natural world than the second law of thermodynamics. It is widely regarded as the quintessential scientific truth, in large part because no exception to it has been recognized by the scientific community during its 150-year history. Over the last 20 years, however, this situation has changed. More than two dozen challenges to it have entered the mainstream scientific literature, the majority of which remain unresolved. (...) Competitions are most exciting when the stakes are high and the competitors evenly matched. After 150 years of preeminence, the second law finds itself in such a contest, where challenges have put its absolute status at risk. The outcome is uncertain, but for the first time it plays in an 'evenly split game.' That is, the second law is in a jeu parti: it is in jeopardy."
The problem may turn out to be sociological, not strictly scientific - our civilization may not be able to survive such a massive surgery, even though malignant tissues are removed.

Since when has light (as in an effect in photons) 1) not started at the same speed in all circumstances, ie irrespective of the speed of that which the photons interracted with - because it is the result of the same atomic reaction, & 2) not continued to travel at that speed unless impinged upon in some way - just like anything else would?
That is all he said in 1905 (always same speed & continue at that speed in vaccuo), and it is, obviously, correct

Einstein said more in 1905:
http://www.fourmilab.ch/etexts/einstein/specrel/www/
"..
.light is always propagated in empty space with a definite velocity c which is INDEPENDENT OF THE STATE OF MOTION OF THE EMITTING BODY."
This means that, if the emitting body starts moving towards the observer with speed v (c>>v), the frequency the observer measures shifts from f to f'=f(1+v/c) but the speed of light the observer measures does not shift at all: c'=c. This is wrong - the frequency does indeed shift from f to f'=f(1+v/c) but the speed of light also shifts: from c to c'=f'(lambda)=f'(c/f)=c+v.

He did not say "more". What I said is all in the sentence you have quoted. In which, Einstein makes two simple, and correct, points about light: 1) the speed it travels at is independent of the 'emitting body' 2) that speed will remain constant unless impinged upon.
You then make an ontologically incorrect interpretation of this. Because the 'light' (as in a specific effectct in photons)is a physically existent phenomenon. Furthermore, at different points in time there are more such physically existent phenomenon. Each 'light' represents the 'thing' (emitting body) which at these different points in time is itself in different existent states (one form of change being spatial position, ie movement). All these are different physically existent phenomena. You conflate them.
To identify what actually happened you would have to establish the spatial position of the body wrt the observer at any given point in time, and that position as at the point in time when the observer received the specific 'light' created by an interaction with the body at the original point in time (ie to establish, whether during the travel of that 'light' from body to observer the relative spatial position of these two entities altered. You would also need to know the environmental conditions that prevailed for that 'light'(ie whether there was anything that impinged upon its original starting speed). The speed of the body is irrelevant, both at the time (because the original speed of the 'light' is determined by an atomic reaction not 'collision')and subsequently (because those are each different existent states of the 'body' and there will be different 'lights' created which represents those).
Light is just a physically existent phenomenon, it is not mysterious, or functions in accordance with different rules to everything else. It is created and travels, and during that travel it can be affected by environmental conditions. Calibrating its speed is effected the same way as for any other entity. It just so happens that we use 'light' to see reality.

hi Don, interesting play. I am not parano , it is god who said me this simple evidence.
Thanks for" good to hear from you" it is nice.
The sphere indeed is better than the point, furthermore , here is the entanglement with its pure number with the central volume, you see the serie Don when the fractal is considered, the ultim fractal of course, of spheres from the main central sphere. So the point can have several volumes when we consider this entanglement, so that depends of the number, isn't it ? :)
How can we consider the points so ? it depends of many things, in all case the spheres have several volumes. so ......... these points are composed by spheres after all ! now if a limit like a wall is considered or this number, that becomes relevant considering the finite groups and the walls !
This entropy can be understood with a more important rationalism at my humble opinion. If we arrive to know this number of this entanglement, so we have the universal fractal and its spheres.With the central sphere like the biggest volume.Now we have a paradoxal conceptulization of the point spherificated if I can say.So , that implies that we have a central sphere more far of the perception of smallest spheres of this entanglement !!! It is very important for a correct understanding of this entraopy and its distribution.
The point does not exist, the sphere and the spheres , yes, the rotations show the road of the spherization.
You know Din, I know that my pc is checked, but you know my faith is so important that even very sad and tired by a difficult life, I will continue !
My parano and problem of health are important but my universal faith is enormous !The spherization is the message of the Universe, several religions name it, God, if you prefer Don, the sciences ar not a play you know but a pure sincere quest towards our truths and foundamentals , rational !
The sphere , Don , is an answer to many things and all rational generalists understand this evidence, this universal Sphere evolves and the quantum spheres build cosmological spheres in a pure 3D perception. This Universal sphere is so fascinating, you imagine the number of lifes and creations inside this universal sphere? It is fascinating and the word is weak. It exists so many planets with lifes , so many galaxies with lifes, even in our milky way, it exists so many lifes I am persuaded. You imagine inside this universal sphere with all the galaxies, it is incredible. And the quantum world is also fascinating. With velocities and volumes different of course but the system is universaly the same. That is why the universal sphere does not turn in my line of reasoning.
Don, not you, you are not in this team of frustrated I hope, I know that I am parano, but not you ? Why ? I ask me even if eckard or Georgina or the otehrs are real or not ?
But I take my meds :)

I am laughing so much in seeing these false experts in geometrical algebars.In fact they confound simply what is the aim of this universal sphere. If already the high spheres are corrupted, where are we going ? in a wall for the humanity.It is not like this that the world can change you know,if already the scientists have this comportment. I have also the "free will" to explain my points of vue. So what is this circus of marketing. If already that the monney is bad distributed, if already that the lies of several scientists imply this sad world. And what after ? Soon we are going to pay the air, it is that ??? Frankly Don, the sciences are not a play but a real quest towards our universal truths. The sciences must be rational and deterministic. The relativity also is deterministic, so why? just for the monney, the power, the vanity and the jealousy more the unconsciousness. It is the human nature simply. You know Don, my faith is very important, I have faith in this universal 3D sphere and its evolution !!! I don't fear to die because the death does not exist simply !!! It is that the real understanding of the entropy and the "mass light" polarization. It exists a small number of persons on this Earth understanding really what is the realtivity and the entropical distribution , SPHERICAL !!! So why they insist, it is the question no ?
perhaps they are simply frustrated because they cannot ponder general works.Or perhaps that the sciences, the theory, is not their road after all simply. But why they insist in showing false sciences, it is the real question.The world is sick Don just due to an ocean of vanity and unconsciousness. Why they continue, because they are simply unconscious and not real foundamental generalists.It is simple like explaination, but perhaps it is too much difficult for them to understand this simple essential evidence.
They speak about observations but they do not observe correctly our 3D contemplations and relativistic perceptions.They must study still a lot of things in fact ....why they continue in their false road? marketing business and the unconsciousness are simple explainations !!!
The hate increases for them, logic they cannot return in the past,they are in a bizare position now, they have the cards in the hands, me I just show my theory.me Alone, and between us, Belgium 1001 The team, 01 , so why they insist, just for their vanity and the monney and their hate, let me laugh.
They caninvent false mathematical musics, that will not change my partitioning and its foundamentals. If they think that they are the chief orchestra, so I suggest thjat they play music with a real universality! The respect and the arrogance they said , and what after, a beer from Belgium at the SRI CIA, no but frankly , let's be rational please if it is possible of course.

Starting with a false theory is dangerous. If it introduces breathtaking miracles (length contraction, time dilation) it may become a religion and kill science in the end. Einstein realised this in 1954:
http://www.perimeterinstitute.ca/pdf/files/975547d7-2d0
0-433a-b7e3-4a09145525ca.pdf
Albert Einstein (1954): "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics."
Clues:
http://arxiv.org/ftp/physics/papers/0101/0101109.pdf
"The two first articles (January and March) establish clearly a discontinuous structure of matter and light. The standard look of Einstein's SR is, on the contrary, essentially based on the continuous conception of the field."
http://www.pbs.org/wgbh/nova/einstein/genius/
"And then, in June, Einstein completes special relativity, which adds a twist to the story: Einstein's March paper treated light as particles, but special relativity sees light as a continuous field of waves."
http://www.amazon.com/Relativity-Its-Roots-Banesh-Hoffmann/d
p/0486406768
Relativity and Its Roots, Banesh Hoffmann: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether."

If you had actually studied relativity, Pentcho, you would know that these effects are measurements relative to the observer's state of motion, and not miracles. You consider them "miracles" because you do not understand the absence of a privileged frame of reference.

Yes length contraction and time dilation are "measurements relative to the observer's state of motion" predicted on the assumption that the speed of light is independent of the speed of the light source. But some implications could prove absurd, and then the assumption is false (provided all other assumptions are true). In my view, the implication that an arbitrarily long object can be trapped inside an arbitrarily short container is absurd:
http://math.ucr.edu/home/baez/physics/Relativity/SR/b
arn_pole.html
"These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. (...) If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn."
http://www.quebecscience.qc.ca/Revolutions
Stéphane Durand: "Ainsi, une fusée de 100 m passant à toute vitesse dans un tunnel de 60 m pourrait être entièrement contenue dans ce tunnel pendant une fraction de seconde, durant laquelle il serait possible de fermer des portes aux deux bouts! La fusée est donc réellement plus courte. Pourtant, il n'y a PAS DE COMPRESSION matérielle ou physique de l'engin."
http://www.parabola.unsw.edu.au/vol35_no1/vol35_no1_2.pdf
"Suppose you want to fit a 20m pole into a 10m barn. (...) Hence in both frames of reference, the pole fits inside the barn (and will presumably shatter when the doors are closed)."

"But some implications could prove absurd, and then the assumption is false (provided all other assumptions are true). In my view, the implication that an arbitrarily long object can be trapped inside an arbitrarily short container is absurd:"
Only if one doesn't know relativity. The relative states of motion of these hypothetical objects are symmetrical. Taking ALL of Baez's explanation, instead of your selective cutting and pasting, this is clear:
"These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn.
Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer.
You are that observer, sitting on the barn roof. You see the pole coming towards you, and it has contracted to a bit less than 40m, in your reference frame. (Does it actually look shorter to you? See Can You See the Lorentz-Fitzgerald Contraction? for the surprising answer. But in any case, you would measure its length as a bit less than 40m.)
So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed.
But consider the problem from the point of view of the runner. She will regard the pole as stationary, and the barn as approaching at high speed. In this reference frame, the pole is still 80m long, and the barn is less than 20 meters long. Surely the runner is in trouble if the doors close while she is inside. The pole is sure to get caught.
Well does the pole get caught in the door or doesn't it? You can't have it both ways. This is the "Barn-pole paradox." The answer is buried in the misuse of the word "simultaneously" back in the first sentence of the story. In SR, that events separated in space that appear simultaneous in one frame of reference need not appear simultaneous in another frame of reference. The closing doors are two such separate events.
SR explains that the two doors are never closed at the same time in the runner's frame of reference. So there is always room for the pole. In fact, the Lorentz transformation for time is
t'=(t-v*x/c2)/sqrt(1-v2/c2)
It's the v*x term in the numerator that causes the mischief here. In the runner's frame the more distant event (larger x) happens earlier. The far door is closed first. It opens before she gets there, and the near door closes behind her. Safe again -- either way you look at it, provided you remember that simultaneity is not a constant of physics.
What if the doors are left shut?
If the doors are kept shut the rod will obviously smash into the barn door at one end. If the door withstands this the leading end of the rod will come to rest in the frame of reference of the stationary observer. There can be no such thing as a rigid rod in relativity so the trailing end will not stop immediately and the rod will be compressed beyond the amount it was Lorentz contracted. If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped in a compressed state inside the barn.
References: Taylor and Wheeler's Spacetime Physics is the classic. Feynman's Lectures are interesting as well."
Now if one doesn't understand these things -- no rigid rod, no simultaneity, no privileged rest frame -- one hasn't learned the first thing about relativity.

Tom,
The conclusion that an 80m pole is "trapped in a compressed state" inside the 40m barn is absurd, in my view. Since this absurdity is a consequence of Einstein's 1905 light postulate, the latter must be false. As an extremely intelligent Einsteinian you don't see the absurdity do you? Then say it explicitly: Arbitrarily long objects can gloriously get trapped, in a compressed state, inside arbitrarily short containers, Divine Einstein, yes we all believe in relativity, relativity, relativity.

Here we go again. “Yes length contraction and time dilation are "measurements relative to the observer's state of motion" predicted on the assumption that the speed of light is independent of the speed of the light source”
No they are not. The hypothesis was that matter alters dimension in the direction of travel as a result of force applied, which also causes an alteration in momentum. This has consequences on both space and timing (not what is commonly referred to as time). It has nothing to do with light, or the relative spatial position/momentum of observers. It is, supposedly, a real effect; subsequent misconceptualisation of the variables and their relationships (particularly with the model of spacetime) has confused this. Whether this effect on dimension actually occurs, and if so, what is the relationship between force and dimensional change, is another issue.
Incidentally, picking up on your point about light and particles/waves. This is irrelevant to the logical point I made in a thread above, when you asserted Einstein’s 1905 postulate was wrong by confusing different existent states of the emitting body and light. What the effect in photons (which we know as light) is, and how it travels, is of no consequence in the sense that it is still an existent ‘something’, and can be affected by the environmental conditions within which it travels. And, more importantly, each ‘light’ is a different existent ‘something’. I do not know, and I am not sure anybody else does, of the exact relationship between light and change in the entity being interacted with. In other words, the extent to which this phenomenon of creating effects in photons upon interaction, ‘captures’ all the change that occurs. The physical process pre-existed the role it has acquired as a result of the evolution of sensory detection in organisms.

You also have a pole, 80m long, which of course won't fit in the barn. (...) If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn."
The pole could be longer, the barn shorter, and yet Divine Albert's Divine Theory says trapping would occur if the relative speed of the pole and the barn is high enough. In other words, arbitrarily long objects can gloriously get trapped, in a compressed state, inside arbitrarily short containers, Divine Einstein, yes we all believe in relativity, relativity, relativity. Do you agree?

hmm... "Divine Albert" ...
If you suggest that physicists are stupid and accept relativity because they believe without questioning in "Divine Albert", then how do you explain that they don't accept Einstein's ideas about quantum mechanics? How do you explain that in these days if one takes side of Einstein in the Einstein-Bohr debate, it is considered a crackpot? Doesn't this prove that in fact most physicists don't accept without questioning what "Divine Albert" said?
As for the relativity of length, probably your personal experience at relativistic speeds makes you say that it can't happen. But this is visible already from electrodynamics: a spherical electromagnetic field actually get contracted to an ellipsoidal shape, as predicted by relativity. There is plenty of experimental data, and if you want to fight it, you have a lot of work to do. Anyway, I congratulate you for challenging the foundations.

Lee Smolin, The Trouble With Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next, p. 226: "Einstein's special theory of relativity is based on two postulates: One is the relativity of motion, and the second is the constancy and universality of the speed of light. Could the first postulate be true and the other false? If that was not possible, Einstein would not have had to make two postulates. But I don't think many people realized until recently that you could have a consistent theory in which you changed only the second postulate."

Joao Magueijo, Faster Than the Speed of Light: The Story of a Scientific Speculation, p. 250: "Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects. Quantum gravity seemed to lack a dam - its effects wanted to spill out all over the place; and the underlying reason was none other than special relativity."

The experimental data in support of special relativity is overwhelming. The predictions of special relativity are 100% confirmed. General relativity is pretty well confirmed; with the only outstanding test being the direct observation of gravitational radiation. The Hulst-Taylor observation of pulsar timing is however indirection confirmation of the physics of gravity waves.

General relativity is pretty well confirmed; with the only outstanding test being the direct observation of gravitational radiation.

We live in an interesting time where many people seem to feel that if science does not conform to their expectations it must be wrong. Creationists reject evolution because the science of evolution does not conform to their theology. Conservative politicos reject climate change science because that science falls outside their ideology. It is all a bit like GW Bush administration where Cheney or Rumsfeld said the intelligence had to be made to fit the policy, which got the US into the Iraq war. Often with such thinking comes conspiracy theories; creationists are convinced there is a secular science conspiracy against God. Climate deniers think there is a science conspiracy to demolish free enterprise, UFO nutsos are convinced there is a big cover up against the “truth,” and on it goes. With physics there are those who reject aspects of modern physics, and they too have ideas about how the whole physics community has been deluded for a century by Einstein or Heisenberg and so forth. A curious alt-geophysics idea making the rounds is the idea that Earth is losing gravity and has been expanding; thus creating oceans in the surface area of the Earth created, and all in contradiction to tectonic theory. There is even a growing community of people who insist that geocentric theory is right, and I am sure that flat-Earth theory is not far behind.
Such people often entrench their minds around these ideas and it is like chiseling barnacles off a boat hull to make them change their mind. Even here with Joy Christian we have a man who argues quite ardently about something which at its core means that 1 = -1. This seems to be a social phenomenon that has become popular in the last few decades. Methods of argumentation involve a range of tactics, from the so called Gish gallop to shaving a point endlessly. The Gish gallop is a strategy of making in rapid sequence a range of objections to established science that can’t be responded to in either the proper time of a debate, or to just simply exhaust the patience of those arguing established science. Often pointing flaws in the arguments of those in alt-science is easy to do, but it is like shooting ducks in a shooting gallery; the damned ducks keep popping back up. The point shaving is seen with the Morris’ (a creationist) statement that every missing gap that is found creates two new missing gaps. In this way the alt-science defendant can keep pushing their case into narrower cracks or seams, whether real or just perceived, of established science and will never concede the argument.
To pad their arguments they further make conspiracy claims, which usually involve some nefarious plot by scientists to deny God, or to push a political agenda, or to conceal their activities (eg reverse engineering UFOs) and so forth. You can take creationism, climate change denialism, UFO claims, and so forth and substitute out the object or subject of consideration, change some verbs or inferences and you have much the same thing. To pad these claims is the conspiracy narrative.
In the case of Velav this involves some elements of the Gish gallop, where he tirelessly posts these anti-Einstein mini-essays here. I think it must be up to 5 or so a day, which are long and would require considerable effort to counter them all. Further, there is the shooting gallery problem; anything that is refuted on Thursday is likely to reappear the following Tuesday.
I think science oriented forums need to monitor out this sort of thing. In effect it might be called a light form of peer review. There is no point in arguing with such people, these arguments can cycle around endlessly (look at the number of posts in the proof-disproof forum!) and such people need to be removed from discussion. If these people have no forum to voice their fatuities in they will go away--- presumably to crankier forums that are further removed from real science.

Lawrence,
Please show specifically where in
Joy's papers that Joy claims or even implies that 1 = -1. If you are going to continue to make such false claims, you need to put your money where your mouth is with a current argument to support such claims. All such claims have been thoroughly refuted on the blog here and by Dr. Christian on the arXiv. If you can't back up your claim with a new argument, then you definitely should stop making such false claims about Joy's model.

Consider the Michelson-Morley experiment. Of the two statements:
A. The speed of light varies with the speed of the light source.
B. The speed of light is independent of the speed of the light source.
A is true, B is false. In 1887 the Michelson-Morley experiment confirmed A and refuted B but at that time B was the cherished one (A had been predicted by Newton's emission theory of light which was completely forgotten) so scientists built a "protective belt" around the false B:
http://bertie.ccsu.edu/naturesci/PhilSci/Lakatos.html
"Lakatos distinguished between two parts of a scientific theory: its "hard core" which contains its basic assumptions (or axioms, when set out formally and explicitly), and its "protective belt", a surrounding defensive set of "ad hoc" (produced for the occasion) hypotheses. (...) In Lakatos' model, we have to explicitly take into account the "ad hoc hypotheses" which serve as the protective belt. The protective belt serves to deflect "refuting" propositions from the core assumptions..."
The protective belt ("contracting lengths, local time, or Lorentz transformations") referred to by Banesh Hoffmann:
http://www.amazon.com/Relativity-Its-Roots-Banesh-Hoffmann/d
p/0486406768
"Relativity and Its Roots" By Banesh Hoffmann: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether."

Jou & Fred,
The simple fact is that Joy writes β_j = β_j(λ) so that that
β_iβ_j(λ) = λ β_i β_j = -λ(δ_{ij} + ε_{ijk}β_k)
which leads to a contradiction with the value of λ. The construction has problems, where if β_i(λ) is Lie algebraic, then the product
β_i(λ)β_j(λ) = -δ_{ij} - ε_{ijk}β_k(λ)
= -δ_{ij} - λε_{ijk}β_k,
However by definition β_i(λ) = λβ_i we also have
β_i(λ)β_j(λ) = λ^2β_iβ_j =
β_iβ_j = -δ_{ij} - ε_{ijk}β_k.
This is inconsistent if λ = -1. You replace β(λ)=λβ by β at some point which changes λ^2 =1 to λ. This permits you to cancel an "unwanted" term that doesn't cancel if you do things right.
This permits you to set -1 to 1. You then keep saying something to the effect that I and other naysayers of your theory don’t understand these local principles the way you do. This would be like somebody offering up a proof on squaring the circle and upon being found wrong by others says, “You don’t understand squaring the circle the way I do.” This begins to sound similar to somebody’s subjective experience of seeing God. You then counter with some pretty negative comments directed at those pointing these problems out, which puts you dangerously close to the crank territory, where defending these positions often resorts to that sort of thing.
It is not my intention of dragging a debate over your “disproof of Bell” here. I will say that if you enter this in the contest and win on the basis of your “disproof” I will have to abandon any respect for FQXi. I also prefer to keep the debate of your “disproof” in the disproof of disproofs area, where given time I suspect enough bits of information will fill the server to cause it to implode into a black hole ;-). I would prefer to avoid further controversy over this, other than to say that what I write above is in a nutshell the inconsistency in your quantum locality “proof.”

I really have no intention of engaging a debate over relativity and your arguments. I dropped dealing with Joy Christian’s stuff (albeit to encapsulate it today here) almost a year ago, for in that case the arguments endlessly cycle. I pretty clearly see that much the same will happen with your anti-Einstein claims as well. I really want to avoid getting on a verbal/text treadmill that can only end by abandoning it. It is not hard for anyone who is reasonably educated in physics to see that somebody who argues against special relativity is a crackpot, and for somebody who does so as adamantly as you must have their brains hopelessly calcified by this nonsense.

"Many physicists argue that time is an illusion. Lee Smolin begs to differ. (...) Smolin wishes to hold on to the reality of time. But to do so, he must overcome a major hurdle: General and special relativity seem to imply the opposite. In the classical Newtonian view, physics operated according to the ticking of an invisible universal clock. But Einstein threw out that master clock when, in his theory of special relativity, he argued that no two events are truly simultaneous unless they are causally related. If simultaneity - the notion of "now" - is relative, the universal clock must be a fiction, and time itself a proxy for the movement and change of objects in the universe. Time is literally written out of the equation. Although he has spent much of his career exploring the facets of a "timeless" universe, Smolin has become convinced that this is "deeply wrong," he says. He now believes that time is more than just a useful approximation, that it is as real as our guts tell us it is - more real, in fact, than space itself. The notion of a "real and global time" is the starting hypothesis for Smolin's new work, which he will undertake this year with two graduate students supported by a $47,500 grant from FQXi."

Einstein's Theory Of Relativity Must Be Rewritten, Jonathan Leake, Science Editor, The Sunday Times - London: "A group of astronomers and cosmologists has warned that the laws thought to govern the universe, including Albert Einstein's theory of relativity, must be rewritten. The group, which includes Professor Stephen Hawking and Sir Martin Rees, the astronomer royal, say such laws may only work for our universe but not in others that are now also thought to exist. "It is becoming increasingly likely that the rules we had thought were fundamental through time and space are actually just bylaws for our bit of it," said Rees, whose new book, Our Cosmic Habitat, is published next month. "Creation is emerging as even stranger than we thought." Among the ideas facing revision is Einstein's belief that the speed of light must always be the same - 186,000 miles a second in a vacuum."

Oh, I so did not want to enter this. My first comment here under the name "emc" was about something not related to Joy's stuff. But then he claimed that any competent quantum physicist would agree with him, and it is that affirmation that I questioned - Joy has no evidence for this claim, which cannot be tested, or the evidence chooses to remain hidden (are they "ashamed of their names"?). And now I am the one who has to prove something. Fred, read from the beginning, and you will see who is the one with the ad hominem.
OK. I take your challenge. But I want to add some conditions (which admittedly are not very original):
1. To have a separate thread (this was about a different topic)
2. Joy convince at least three FQXi or PI members who are quantum physicists, to constitute a jury and to arbitrate the debate under their real names. I agree to let Joy Christian select those fellows.
3. Each point raised against or in defense of Joy's theory will be reviewed and evaluated by the jury, and the result of the evaluation will be made public.
Optional:
- Avoid insults and name calling. I put this to be optional because I don't want the jury to disqualify Joy because he is making personal attacks. I want to win the debate on the grounds of the arguments.
- Since I see that Joy's friends intervene all the time, I agree to allow them to contribute to the debate, if also opponents of Joy's theory are allowed.
- Once everything is prepared for the debate, I will let Joy decide if he wants me to use my real name, or continue to use "emc".
I take your challenge, with the above conditions. Accept them, or accept that when you called me "coward", this applies in fact to you.

Dear Joy,
Thank you for accepting my conditions to the challenge.
In fact, I already invited you to a debate like this last year, on
one of these forums.
You asked for my qualifications. I have a masters in Differential Geometry with applications to theoretical physics, and now I am enrolled in a PhD in Differential Geometry. I work for some years as a computer programmer specialized in geometric algorithms.
I used the nick "emc" as reference to a joke in a
parody about Einstein. It had nothing to do with you, since the comment was for someone else, but somehow the discussion became about some of your statements (LC mentioned you in a reply to emc (me), so you replied, so emc replied etc).

Cristi Stoica

Fred,
The discussion concerned Joy's affirmation that any competent physicist would agree with him. What I did was to put his own words against his statement. Now you claim that quoting Joy's own words is an "ad hominem".
And to be clear: I did not ask him to prove the value of his work by telling us what physicists agree with him. I don't take the opinion of the "competent authorities" as proof of the value of someone's work. It was Joy who introduced the appeal to authority, by claiming that any competent physicist would agree with him. So it was natural to ask him to give examples of such competent physicists. You said there are plenty, but they remain hidden, maybe because they will be witch-hunted by the authorities or so. There is more evidence for Big Foot.
About my arguments concerning his papers, you did not refute any of them, you just repeat endlessly that you did. And Joy knows, that's why he backed of. I decided for last year to stop arguing with him and his worshipers (what evidence do you have that I am Bell's worshiper? Instead, you proved to be Joy's), unless the debate is arbitrated. If you want to see my cards, convince Joy to honor his promise. Don't try to attract me in your dishonest kind of fight where anything but math and physics goes.
Joy said "I agree to ALL of your conditions if you reveal your real name and qualifications first."
I asked "Do I have your word that you will continue to agree after I reveal my full name and qualifications?"
Joy replied "I have already given you my word several times."
Then he backed of, proving the value of his word.
No trick of yours will erase this.

That is a veiled ad hominem if I have ever seen one. So you can stop lying about what you did right now. Furthermore, that post you did referring to something on Scott's blog had nothing to do with the discussion. You posted it simply as a veiled ad hominem attack.
All your previous arguments were simply nonsense and have been shown to be that on this very blog. So... ya got any new arguments? Or... do you even want to go over any old arguments. But my guess is you just want to continue with your ad hominem nonsense.

Joy never broke his promise. He said he would do it as soon as you got your PhD. So you have something to look forward to after your studies. I never did see you say anything about when the debate need take place. In legalese it is called "time is of the essence".
I told you to go ahead with your arguments; even the old ones if you wish. How is that mud slinging? Seems you are the one here that wants to keep slinging mud around. Ya got a physics or related math argument about Joy's model? Go for it. Get 'em off your chest.

That is right that you didn't say a clause like that; you should have specified a date and time as to when the debate is to take place. You didn't. Joy didn't invoke anything. He agreed to the debate when you get your PhD. When might that be?
I'm not going to bother to look up your arguments in the old threads as they are way too slow and they probably have been refuted already since then anyway. Post them now or don't. Your choice.

It appears I can post to the blog entries, but I still can't post to the forum entries. I am not sure what is going on. My suspicions I indicated above are however reduced.
There are two curious characters here. One is Pentcho who thinks Einstein is all washed up. Pentcho is clearly a crank. Then there is JC who thinks Bell is all washed up, but anyone who presents problems with his disproof finds that JC keeps claiming how the goalposts are moved to elsewhere.
This topic is interesting, but the removal of an operating assumption in current physics is far more subtle than just denying something about current physics. This will happen where quantum physics and general relativity merge. With quantum mechanics there was a huge reduction in the numbers of degrees of freedom. In fact the complete sets of commuting operators reduced it by half. The merging of quantum mechanics and general relativity will be another massive reduction in the number of fundamental degrees of freedom in the universe. This means that the amount of data, or qubits, necessary to describe the universe is far smaller. The subtle question is how are physical postulates employed today either removed are drastically revised to make this happen.
I will say that JC's "sign change" which reduces nonlocal variables to local ones does the opposite. JC is tacitly increasing the number of degrees of freedom.

The problem is that Einstein is all washed up in the quotations I refer to, Lawrence. For instance, Carl Mungan and Roger Barlow suggest that, when the observer moves toward the source, "the wave speed is simply increased by the observer speed". That is, the speed of the light wave, as measured by the observer, varies with the speed of the observer. Are Carl Mungan and Roger Barlow cranks?
http://www.usna.edu/Users/physics/mungan/Scholarship/Doppler

Carl Mungan: "Consider the case where the observer moves toward the source. In this case, the observer is rushing head-long into the wavefronts... (...) In fact, the wave speed is simply increased by the observer speed, as we can see by jumping into the observer's frame of reference."
http://www.hep.man.ac.uk/u/roger/PHYS10302/lecture18.pdf
Roger Barlow, Professor of Particle Physics: "Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c+v)/(lambda)."

"JC is tacitly increasing the number of degrees of freedom."
Lawrence, you, like Marc Holman, think this is a bad thing. In fact, though, there's no contradiction between the reductionist paradigm of science and Joy's program. The introduction of the point at infinity (caused by compactifying R^3 to S^3) increases (or rather, explicitly acknowledges) the degrees of freedom on R^3 but constrains the measure space to the manifold of S^3. The equator of this simple Riemann sphere admits only 3 discrete results (+ 1, - 1 and i)so one *should* be able to easily see the binary dichotomy, and the reason why Joy's input argument [E(a,b)= - a.b] reduces to perfect anti-correlation for a continuous measurement function of results observed in a bounded length of time. For an orientable outcome, it *has* to. Without nonlocality, nonrientable R^3 admits infinite degrees of freedom; Joy presents a true local realistic model of finite measure with classical time symmetry.
All this noise about "Joy's supporters" being some kind of cult following is a crock. It couldn't have escaped one's notice that while I have been an outspoken supporter of Joy's research, he has shown no support for mine -- and with good reason. I disagree with the fast and loose characterization of the role of a mathematical model in physics, and I've been outspoken about that, too. We can't have theorems "disproven," or else physics becomes a kind of alchemy, mixing some arcane symbols with experimental observations and cobbling an a posteriori explanation for the outcome. In other words, anything goes.
In fact, though, that alchemy metaphor fits what standard quantum theory has become. All that makes it (and ever made it) coherent, is the assumption of nonlocality. So I think it was completely wrong in the first place to speak of "disproving" Bell's theorem. It works quite well with the assumption of nonlocality, as well as Newtonian classical physics works in its own limit. What Joy has done is to show that quantum pair correlations to infinity are not independent of classical geometry (generalized to topology), that there is therefore no boundary between classical and quantum domains -- or as Einstein put it, "All physics is local."
I don't deny that Joy's mathematical model needs improvement, to clarify beyond doubt that it stands completely independent of experiment, which would lay forever to rest these bogus strawman arithmetic arguments. I understand the criticism, but it is baseless. Joy's model has nothing to do with probability theory, Hilbert spaces or any other trappings that attend standard quantum theory.
Your argument that if Joy's theory had merit, that you would have heard about it by now, is simply ridiculous. Take as an example Leslie Lamport's April 2012 Found. Phys. paper
"Buridan's Principle," IMO a seminal contribution to the computational study of the physics of continuous functions, which was written almost three decades ago. Lamport recounts the history of the paper in part:
"My problems in trying to publish this paper and [22] are part of a long tradition. According to one story I've heard (but haven't verified), someone at G. E. discovered the phenomenon in computer circuits in the early 60s, but was unable to convince his managers that there was a problem. He published a short note about it, for which he was fired. Charles Molnar, one of the pioneers in the study of the problem, reported the following in a lecture given on February 11, 1992, at HP Corporate Engineering in Palo Alto, California:
"One reviewer made a marvelous comment in rejecting one of the early papers, saying that if this problem really existed it would be so important that everybody knowledgeable in the field would have to know about it, and 'I'm an expert and I don't know about it, so therefore it must not exist.'"
'Nuff said.

The general progress of physics has been about reducing the number of degrees of freedom. In fact it goes back to Galileo who realized that the accelerated mass was observed in all inertial reference frames with the same acceleration. If you think about it that was a huge reduction in the number of cases one needed to treat in a special way; we call it Galilean relativity. Kepler did the same, where the equal area ~ equal time is a huge simplification that reduces the number of specific calculations needed. The same holds with Newton and up to Einstein and the quantum founders. The next step will be entirely the same; there will be a huge reduction in the number of fundamental degrees of freedom.
The large number of degrees of freedom in the universe is due to entanglement entropy, or entropy associated with event horizons. Our observable universe, or the observable region out to the particle horizon χ = ∫dt/a(t), is entangled with the rest of the universe beyond that horizon. We are limited in our observations by the entanglement entropy associated with that horizon. There are then limits on the observables we currently think are absolute in QM, such as those in a complete set of commuting operators. If one tried to observe an observable out to 10^{30} decimal points the data involved would turn your apparatus into a black hole. That is a fundamental limit, identical to the cosmological issue, and it stems from the fact quantum states have representation in configuration space or spacetime via this entanglement. The configuration space of a quantum state is then fundamentally reduced to “no representation,” which would then massively reduce the number of degrees of freedom in the universe.
I think this means the universe has only one type of elementary particle. There is only one electron, one photon, one up quark with blue-red charge, one tau, one W one…. . What we see as the large number of these particles is then a multiplicity induced by their entanglement across event horizons. Event horizons then impose locality of field amplitudes and induces this enormous duplication of quantum states and their various configuration space representations. This configuration space representation has its complement in a momentum space representation. So the photons reaching my eye have a large range of momenta I perceive as colors, but on a deep level this is just one photon entangled across the cosmic horizon with specific configuration variables.
What I see is ultimately an illusion.
Quantum gravity implies spacetime is a geometric representation of a field that exhibits quantum properties. General relativity is a geometric theory of spacetime, and quantizing gravity which requires a description of spacetime that is beyond the causal and local configuration imposed by GR. QFT is local, but the fundamental (diffeomorphism-invariant) physical observables of quantum gravity are necessarily nonlocal. QFT takes causality as a fundamental postulate, but in quantum gravity spacetime geometry has complementary description, by way of consequence light cones and the causal structure are themselves subject to quantum fluctuations. Time evolution in quantum field theory is determined by a Hamiltonian operator, but for spatially closed universes, the natural candidate for a Hamiltonian in quantum gravity is identically zero when acting on physical states. Quantum mechanical probabilities must add up to unity at a fixed time, but in general relativity there is no preferred time-slicing on which to normalize probabilities.
The transition from quantum gravity to classical gravity imposes strict light cones and classical horizons in a spacetime with strict locality and causality structure. This results in a huge redundancy in quantum fields with various configuration variables established by locality on the classical spacetime.
Cristi: This connects in part with your work on removal of spacetime singularities. Your idea appears to be a type of analytic continuation which uses a complex structure to remove the singularity. It has been a while since I have looked at your work, so I may be somewhat amiss with this assessment. I think there is some nonlocal duality between fields on the holographic horizon and the singularity in a black hole. Field theoretic content on the two structures can be transformed into each other. It is not hard to seen that the event horizon for an accelerated observer can be transformed into a singularity-like structure.
We think of the case of an observer stationary above a black hole event horizon. The accelerated frame near the event horizon observes the outside world “speed up,” for units of proper time on this frame correspond to very large units of time is asymptopia. As the accelerated frame approaches the horizon, which requires a larger acceleration, we may think of adiabically moving this situation to the stretched horizon. The distinction between this frame and the frozen appearance of a freely falling frame on the stretched horizon as observed from the outside are indistinguishable. This flies in the face of some standard physics, where physics is written according to inertial frames. There is an asymmetry between inertial and accelerated frames, which I think is in greater generality removed
For the accelerated observer the life time of the exterior world races by in a flash. For a stellar mass black hole it requires billions of g-forces to remain a few meters from the horizon, and to get within centimeters requires about a billion billion g's of acceleration. If by some means an observer could do this the outside world would be racing by, say for a small proper time with t = g^{-1} cosh(gs). So the proper time element is s ~ g^{-1}ln(gt) for a time unit t outside. As a result for t the lifetime of the black hole ~ 10^{67}year, g in units of distance ~ 1cm ~ 10^{-10} sec ~ 10^{-17}year the proper time the observer on the accelerated frame observes the BH to evaporate is
s ~ 5x10^{18} years.
This is much shorter than the BH life time measured by the exterior world. Assume you get that acceleration up to 10^{33}cm^{-1} or 10^{43}sec^{-1} or 10^{50}year^{-1}, then you are hovering practically on the stretched horizon. The BH evaporates in about 10^{-42} seconds, or close to the Planck unit of time! Bang!; which means all that ingoing and outgoing radiation which interacts with the black hole hits you at once is a colossal thunderclap. The event horizon appears for larger g close in to be more of a singularity, or a surface region of huge energy density that is radiating and absorbing energy at a ferocious rate.
The accelerated observer ever closer to the event horizon observes a singular physical situation. This is also found for the case of a black hole approaching the extremal condition, where the horizon is replaced by a singularity. There is an exchange between horizons and singularities, or a complementary condition for observables on them. The event horizon with its holographic fields or strings has those fields annihilated by the nonlocal occurrence of fields or strings outside the black hole, or equivalently a tunneling of fields from the interior singularity to the outside. If an observer watches the horizon ever closer by accelerating ever more to extreme g the horizon appears more and more as the singularity where fields are intensely blue shifted or in the UV domain. The interior singularity to an infalling observer is much the same. In that case fields are divergently blue shifted as they approach the singularity.

Not if the present contest is successful and basic principles are shown to be wrong. For instance, an initial version of the second law of thermodynamics states that all heat engines working reversibly between the same two temperatures, T1 and T2, have the same efficiency. Obviously a huge reduction in the number of degrees of freedom but now the reverse process - a huge increase in the number of degrees of freedom - will take place if the second law is wrong. The case with Einstein's 1905 light postulate is analogous.

The statistical basis for the thermodynamics according to bits of information is from the Shannon-Khinchon theorem (proven) that the unit of entropy is
s = -k p(n) log(p(n)).
The summation over all possible p(n) is then S = sum_n s or S = ∫ds. For simplicity we assume p(n) = 1/n, for a microcanonical ensemble at maximum entropy. The result is that for N = max number of bits that S = k log(N). Hence if N is larger S is larger; the log function is convex. The number N represents the size of the volume Ω in phase space a system occupies, so the general entropy formula is then S = k log(Ω) --- which is engraved on Boltzmann’s gravestone.
It is clear that you are terribly confused about many things, such as saying above that a Lorentz contracted rod is in some state of compression. You are also seriously pissing up a rope if you are trying to counter statistical mechanics and thermodynamics. Please learn the real stuff instead of hammering away on nonsense.

John Baez says the rod is in a compressed state:
http://math.ucr.edu/home/baez/physics/Relativity/SR/ba

"These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. (...) If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn."
Other Einsteinians teach the rod is contracted but without compression:
http://www.quebecscience.qc.ca/Revolutions
Stéphane Durand: "Ainsi, une fusée de 100 m passant à toute vitesse dans un tunnel de 60 m pourrait être entièrement contenue dans ce tunnel pendant une fraction de seconde, durant laquelle il serait possible de fermer des portes aux deux bouts! La fusée est donc réellement plus courte. Pourtant, il n'y a PAS DE COMPRESSION matérielle ou physique de l'engin."
Finally, according to some Einsteinians, special relativity predicts length elongation as well:
http://math.ucr.edu/~jdp/Relativity/Bug_Rivet.html
John de Pillis Professor of Mathematics: "In fact, special relativity requires that after collision, the rivet shank length increases beyond its at-rest length d."
Anything goes in Einsteiniana.

Dear Pentcho,
I congratulate you for questioning the foundations. This job should be done constantly, especially on the principle widely accepted. This thing should be encouraged by the mainstream, and I think they don't do this enough. The reason is simple: time. Most physicists are very busy with two things: keeping them updated, and doing and promoting their own research. To be kept updated in these days is nearly impossible, and that's why most physicists are forced to give up the love to learn by checking everything by themselves, and to replace it with accepting many things at second hand, on the basis that they were checked by others (the "peers"). This is bad, but it is efficient for two reasons: it allows you to appear that you know more, and to agree more with the others. Agreeing more with them makes them agree back, and this helps you promote your work. And for a physicist this is very important, because they have to publish, or they will perish. They are not happy with this, and they will want to go back to their early youth, when they had more time to question anything, and to explore alternatives, but that's life. After a time, they forget their initial impetus, having now other motivations.
But I think that any good physicist who knows relativity, at some point in his childhood questioned it, as you do. As you surely know, learning relativity doesn't limit at reading popular or introductory literature (even people like John Baez, when try to explain the things to others, may dumb down the explanation, or at least use too much metaphor).
For some reason, when people learn relativity, when they check the calculations, apply the principles to solve real problems, understand the connections with other principles of physics, their objections fall one by one. After a time they consider they were silly for doubting these principles, and probably they will try to be more efficient, by questioning less what they learn. Some of them, who skipped the phase of questioning relativity, or who did not finish it, learn to pass the exams, and may become acknowledged scientists in the new mainstream. Then, they remember their questions, and re-take their inquiry, and publish papers in which they claim that relativity has some issues. Maybe it is their late childish exploration, or maybe they really found some issues. To really know, one should really understand both relativity and their proposed alternatives. Just selecting quotes may lead to any conclusion.
I consider relativity a very good theory. I did my share in questioning it in the childhood. I love it, because it leads from simple principles to a wide net of consequences, which penetrate the entire physics. I love it because I see it everywhere, and not because Einstein is so much promoted as the ultimate genius. In fact, I consider that he should share more of his merits with Lorentz, Poincare, Hilbert, Schwarzschild, Riemann, Clifford, and probably others. Well, he was great, and I love him, but so were others. I am telling you this because you think that people accept relativity, which you consider rubbish, because they cherish so much Einstein. If this would be so, they would have to accept Einstein's view on quantum mechanics too, and most don't.
I know that relativity is counterintuitive. For some reason, Nature seems to care for us to understand her - probably because we needed this to survive. But some phenomena are far from our usual experience and need of survival. For example the Lorentz "contraction" at velocities near the speed of light. If the tunnel has 40m, and the train 80m, how can a train at a velocity very close to the speed of light be "trapped" inside the tunnel?
From the viewpoint of the passengers the train is not contracted, it has 80m. In fact, they see the tunnel contracted at 20m, and they see the train being only 25% inside the tunnel. If there are two doors, at the ends of the tunnel, an observer which is immobile with respect to the tunnel may see them both closed, and the train trapped inside. Just for a fraction of a second. But for the passengers, the doors are not closed simultaneously. The front door is closed, and opens just a tiny fraction of a second before the front of the train exits the tunnel. Then, after the back of the train enters the tunnel, the rear door may become closed, but for the passengers, 3/4 of the train is already out of the tunnel. So, the passengers conclude that the tunnel trapped the front of the train at t1, and the back of the train at t2, where t1

Some of them, who skipped the phase of questioning relativity, or who did not finish it, learn to pass the exams, and may become acknowledged scientists in the new mainstream. Then, they remember their questions, and re-take their inquiry, and publish papers in which they claim that relativity has some issues. Maybe it is their late childish exploration, or maybe they really found some issues. To really know, one should really understand both relativity and their proposed alternatives. Just selecting quotes may lead to any conclusion.
I consider relativity a very good theory. I did my share in questioning it in the childhood. I love it, because it leads from simple principles to a wide net of consequences, which penetrate the entire physics. I love it because I see it everywhere, and not because Einstein is so much promoted as the ultimate genius. In fact, I consider that he should share more of his merits with Lorentz, Poincare, Hilbert, Schwarzschild, Riemann, Clifford, and probably others. Well, he was great, and I love him, but so were others. I am telling you this because you think that people accept relativity, which you consider rubbish, because they cherish so much Einstein. If this would be so, they would have to accept Einstein's view on quantum mechanics too, and most don't.
I know that relativity is counterintuitive. For some reason, Nature seems to care for us to understand her - probably because we needed this to survive. But some phenomena are far from our usual experience and need of survival. For example the Lorentz "contraction" at velocities near the speed of light. If the tunnel has 40m, and the train 80m, how can a train at a velocity very close to the speed of light be "trapped" inside the tunnel?
From the viewpoint of the passengers the train is not contracted, it has 80m. In fact, they see the tunnel contracted at 20m, and they see the train being only 25% inside the tunnel. If there are two doors, at the ends of the tunnel, an observer which is immobile with respect to the tunnel may see them both closed, and the train trapped inside. Just for a fraction of a second. But for the passengers, the doors are not closed simultaneously. The front door is closed, and opens just a tiny fraction of a second before the front of the train exits the tunnel. Then, after the back of the train enters the tunnel, the rear door may become closed, but for the passengers, 3/4 of the train is already out of the tunnel. So, the passengers conclude that the tunnel trapped the front of the train at t1, and the back of the train at t2, where t1 is less than t2. But in no case the entire train at the same time.
So who're right, the passengers, or the people walking near the tunnel? Both. Assume that the train displays the time on two clocks, one in the front, and the other in the back. Before leaving the station, the two clocks show the same time. When passing through the tunnel, even if it is trapped for a tiny fraction of a second, an observer from tunnel's frame will see that the two clocks show different times: t1, and t2. So they will know that this contraction is not real for the train, but it is due to the way the see the train. Not just an optical illusion, because it involves four dimensions. But thinking in four dimensions, and drawing Minkowski spacetimes, would help.
Now, the difficulty of understanding is not that there are four dimensions, but some of those who understand feel cooler to suggest that they are some gurus who transcended the three dimensions. In fact, the problem of the train and the tunnel requires only two dimensions, one space dimension, and the time. So, a one plus one Minkowski diagram will suffice. I will not draw it, maybe it is better if you will do so. Not because by doing this I am sure you will understand and accept relativity. But because, even if you continue to reject relativity, it is better for you to understand it, to "know your enemy" so to speak. Or maybe you understand relativity, but you just disagree, I don't know.
I like very much people who question the foundations (this doesn't mean I have to agree with them). Critical thinking is a good tool, and it has to be used both ways. Question everything others tell you, and question what you think you understand from what they tell. A complete usage of critical thinking require not only to question the others, but to submit to a thorough checking our own understanding. Understanding relativity, and showing this to an expert, puts you in a much better position to expose your own doubts and ideas. Because people are busy, don't have time to make sense by themselves of what you tell them. If I were in the position to contest relativity, I would first try to work out the basic notions, and understand what they mean, until I would be able to pass an exam, and to write an introduction to the subject, in which I just present the theory, with neutrality (without praising its merits or despising it). Then, I would try to take the arguments of the theory and attack them. It is difficult. Maybe a good essay for this contest will have an introduction in which you prove that you understand relativity and establish a common language, and a body in which you expose the mistakes of relativity. Quoting from experts who doubted relativity would help only as an argument from authority (unless they did not in fact doubt it, but tried to present what a person who doubts would say). The best would be to point the mistakes (if you will still believe there are mistakes), if possible at a mathematical level.
Good luck,

“What I see is ultimately an illusion”
No, what is receivable which can be sensed by organisms might, from the perspective of its acquired role in sensory detection, best be characterised as a representation rather than an illusion. There is a definable physical process involving physically existent phenomena. The description ‘representation’ reflects the fact that:
1 what is receivable is not the reality being considered, as such, but the result of an interaction with it
2 that resultant effect may be altered in some way during its travel
3 there is no reason to assume that these physical interactions, which have become usable with the evolution of sensory detection in organisms, fulfil this acquired function perfectly, eg a certain amount of change or some existent states may not be ‘captured’ or they may in some way distort the original state.
Paul
PS: re your next paragraph and the post in general, if you represent time as the physical phenomenon that it corresponds with in reality, then the problems you refer to vanish. Put the other way around, the core problem is the underlying misrepresentation as to how reality physically occurs.

I like a theorem by Wiener/Khinchin (writung Khintchon you made a typo) because I see it a confirmation of my opinion that the putatively additional degree of freedom with the usual description of a function of time in C instead of R+ is just an illusion. I see the representation in C twice redundant. Real part and imaginary part, past and symmetrically to it anticipated future are entangled pairs that can be calculated from each other. So I guess, JC is formally correct while on the same detour as virtually all theory of signal processing and non-Galilean relativity.
I appreciate your preference for minimalistic representations.
You seem to declaring cranks all those hundreds of experts who questioned SR in particular by signing petitions. I would rather suggest waiting until the SKA (square kilometer array) operates after 2016. Of course, Einstein was correct when he reacted to the 100 reasons why SR is wrong with the argument: A single compelling one would be sufficient.

I think Baez' use of the word compressed is a bad word choice. Besides the observer riding along with the rod observes no change in its length. There are no internal compressing forces on the rod.
Paul, the reality I observe could be said to be "hard enough." It is not advised to step in front of a moving truck with the idea it is an illusion. However, I think the majority of what we call reality is little more than a sort of holographic or Moire phase pattern that has no fundamental depth.

Concerning the 80m pole (train) trapped inside the 40m barn (tunnel), you are changing the problem. Trapping does not last "just for a fraction of a second". Rather, special relativity predicts that arbitrarily long objects can remain trapped inside arbitrarily short containers FOR GOOD:
http://math.ucr.edu/home/baez/physics/Relativity/SR/bar
n_pole.html
"These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. (...) If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn."
http://www.parabola.unsw.edu.au/vol35_no1/vol35_no1_2.pdf
"Suppose you want to fit a 20m pole into a 10m barn. (...) Hence in both frames of reference, the pole fits inside the barn (and will presumably shatter when the doors are closed)."

Pentcho,
What Baez does is to add to the problem of the train and tunnel the twist that the two doors of the tunnel will remain closed. Relativity predicts that for a short duration the train will be seen from the reference frame of the tunnel as being trapped.
What comes next, the twist, is not the prediction of relativity, it is a speculation of what could happen if the two doors will remain closed, and if they are able to stop the train, or the pole if you wish. To stop them means to make it slow from a velocity closed to that of light, to 0. Normally, this would blow up any door, and if it wouldn't, the train would blow up, and the mountain with the tunnel would be moved by the impact, and if it doesn't, then it comes what you said. The train would be stopped, and it will remain compressed, I mean compressed as you would compress it at a car cemetery. So, when Baez said "compressed state", I understand now that he really meant compressed.
If there would exist such an extreme tunnel, with such good doors, then this will reduce to the impact of the train at almost c, to its compression during the impact, etc. This is not a problem, unless you want the train or the pole to be a perfectly rigid object.
So the conflict is between relativity and the existence of objects with these magical properties. While the relativistic effects are well studied by experiments, I don't know of any evidence of such objects with such extreme properties.

Cristi

Compressed (or contracted) is what they hypothecated. The “observer riding along with the rod observes no change in its length” because the observer is also an entity and is similarly being compressed, by definition. The assumption there being that, although comprising different forms of matter, both are similarly affected by the same force. The comparison is really entity to entity. Which does raise the question as to whether the observer would see it that way. In the case of that lorry, you receive photon based representations of the entity first, but do not have enough time differential before you receive a feeling sensation! – unlike pigeons that see the world at a much faster rate.
I am not sure why people keep on bringing up SR. Einstein stated clearly what it constituted, that is, a conceptualised circumstance where there was no gravity (ie force) so bodies are fixed in shape, rays of light move in straight lines, there is only uniform rectilinear and non-rotary movement and Euclidean maths can be applied. I think the problem is that people think all that was written in 1905 equals SR, which it does not.

No it does not. SR involves no alteration in the dimension of objects whatsoever. Here is the man himself telling you so:
“Provided that they are in a state of uniform rectilinear and non-rotary motion… The validity of the principle of relativity was assumed only for these reference-bodies, but not for others (e.g. those possessing motion of a different kind). In this sense we speak of the special principle of relativity, or special theory of relativity” (Einstein 1916 SR & GR Section 18 para 5)
“The special theory of relativity has reference to Galileian domains, ie to those in which no gravitational field exists…In gravitational fields there are no such things as rigid bodies with Euclidean properties; thus the fictitious rigid body of reference is of no avail in the general theory of relativity. (Einstein SR & GR 1916 Section 28)
Apart from misinterpreting the consequences of what was actually said, you are presuming that all that written in 1905 equals SR, rather than listening to what the man himself tells you it is.

I admit that the transition from Einstein's 1905 light postulate (the premise) to the strange effects accompanying the permanent trapping of an 80m pole inside a 40m barn (the conclusion) is not reductio ad absurdum par excellence. Still in my view the feeling that length contraction is perhaps too awkward should emerge even in the heads of faithful Einsteinians. Then this feeling should become unbearable in the context of the Michelson-Morley experiment. In 1887 the experiment UNEQUIVOCALLY confirmed the assumption that the speed of light varies with the speed of the light source (as predicted by Newton's emission theory of light) and refuted the antithesis which was to become Einstein's 1905 second postulate - that the speed of light is independent of the speed of the light source. It was the length contraction hypothesis that completely reversed the interpretation of the experiment - the null result became compatible with the antithesis and incompatible with the Newtonian concept:
http://www.amazon.com/Relativity-Its-Roots-Banesh-Ho
ffmann/dp/0486406768
"Relativity and Its Roots" By Banesh Hoffmann: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether."
http://www.pitt.edu/~jdnorton/papers/companion.doc
John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day."
http://philsci-archive.pitt.edu/1743/2/Norton.pdf
John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

It has nothing to do with light, time, observers, etc, etc. The process whereby they came up with this conclusion, and whether or not is is actually valid, is irrelevant to the fact that this is what they asserted, and everything flows from there. Or would have done, had there not been a misinterpretation of the interaction of the variables which, funamentlly lead to timing becoming the surrogate for dimensional alteration.
Here is Lorentz (1892 para 3):
“It consists of the assumption, that the line joining two points of a solid body doesn't conserve its length, when it is once in motion parallel to the direction of motion of Earth, and afterwards it is brought normal to it. [The difference when comparing the two motions in the same dimension being p2/2V2] . Such a change in length of the arms in Michelson’s first experiment, and in the size of the stone plate in the second, is really not inconceivable as it seems to me”.
Simple translation: matter alters dimension in the line of motion when the rate of motion is caused to alter, and once the cause ceases it reverts to its ‘normal’ dimension. [The cause was subsequently attributed to gravity].
Here is Poincaré (July 1905):
“An explanation was proposed by Lorentz and Fitzgerald, who introduced the hypothesis of a contraction undergone by all bodies into the direction of the motion of earth and proportional to the square of aberration; this contraction hypothesis would become insufficient, however, if one were to assume the postulate of relativity in all its generality.
It is thus necessary to return from here to the theory of Lorentz; but if one wants to preserve it and avoid intolerable contradictions, it is necessary to suppose a special force which explains at the same time the contraction and the constancy of two of the axes. I sought to determine this force, I found that it can be compared to a constant external pressure, acting on the deformable and compressible electron, and whose work is proportional to the variations of the volume of the electron.
Simple translation: Lorentz was correct about dimension alteration, except for a minor tweek which I have provided. [This was a reaction to some commentator who’s name I have forgotten]
Here is Einstein (Foundation of GR 1916):
“The unit measuring rod appears, when referred to the co-ordinate-system, shortened by the calculated magnitude [equation (71)] through the presence of the gravitational field, when we place it radially in the field. The gravitational field has no influence upon the length of the rod, when we put it tangentially in the field [equation (71a)]…But a glance at (70a) and (69) shows that the expected difference is much too small to be noticeable in the measurement of earth's surface”
Simple translation: the effect exists but is too small in the context of earth.

Lawrence, you wrote, "If an observer watches the horizon ever closer by accelerating ever more to extreme g the horizon appears more and more as the singularity where fields are intensely blue shifted or in the UV domain. The interior singularity to an infalling observer is much the same. In that case fields are divergently blue shifted as they approach the singularity."
That's exactly right. And it's the very reason that I have been emphasizing that the continuous measurement function as described by Joy's framework is nondegenerate near the singularity. What one has to account for, is that EVERY continuous measurement function (Lamport) contains a singularity, in which the measure diverges to the left or right. In a fully relativistic model (which Joy's demonstrably is) and given that the universe is expanding, every point EXCEPT ONE is a finite distance from every other; one point at infinity decides -- in the bounded length of time of the measurement -- between left or right, which TO THE OBSERVER must appear as a continuous function nondegenerate near the singularity. Allowing that there is no privileged frame, the objective case is only clear on one side of the record at a time (hence, Joy's unjustly maligned input argument, E(a,b) = - a.b). Classical time symmetry -- exactly as sustains special relativity -- restores the objective case. The moon is there when no one is looking, as is the singularity when no one is measuring.

TH Ray, Cristi et al,
This transformation between holographic fields on a stretched horizon and a singularity has absolutely nothing to do with JC’s locality claim of QM. Cristi has found ways the singularity of a black hole can be transformed away or removed by analytic extension. This is similar to Hawking’s imaginary time argument. The removal of the internal singularity in a black hole is then equivalent to removing the UV spectrum fields on an event horizon to the IR spectrum by turning off the acceleration g, g --- > 0, so the observer is on an inertial frame. This does not have much to do with anything JC is claiming.
As for the moving rod, there is clearly no compression force that contracts it as seen in a frame moving relative to the rod. Trapping the rod in a box and trapping its contracted length involves accelerated reference frames. This is a bit of a complicated question involving how an object that has an extended length can be placed in the same accelerated reference frame. There is also an optical component to this as well called the
Terrell rotation This optical effect happens to largely cancel the Lorentz contraction, but relativistic motion still distorts the appearance of objects nonetheless.
I suppose maybe this gets touches on what Paul says above. Einstein laid down the transformation properties of spacetime in 1905. There are of course other things one can derive in special relativity, such as these funny optical effects. I will say that I am annoyed and tired of this constant drum-fire of ignorance and misinformation that Pentcho keeps peppering this blog with.

If the universe/reality is expanding, that is an omnipresent effect, ie there is no point of reference to detect it when considering everything that is existent at any given point in time. It is only detectable by comparing change over time and discerning a certain irregularity from that which would otherwise have been expected.
Infinity is not a point. By definition, it does not exist. For any judgement one must involve a reference, but that must exist, otherwise comparison (ie judgement) is impossible. Having chosen any given reference (no one being privileged) then one must continue to deploy that reference, otherwise the outcomes are not comparable.
Observation is distinct from reality (as in the sense of what is being observed). Because it is not reality that is observed, but a photon based representation thereof resulting from an interaction therewith. Which is received by the observer some time after the existent state (reality) has occurred, and indeed by then been superseded by another.

The effect in light was deemed to be the same as the same as the effect in dimension. Because that famous null result was translated as being: the light effect does exist, it is just being cancelled out by an alteration in dimension. But as I keep on saying, the derivation of an hypothesis is irrelevant. It was declared, and not rescinded. Moreover, again as I keep on saying, what happens in light is entirely separate from what happens in the reality being depicted by it. They are physically different existent entities. So what happens with light is irrelevant anyway in terms of determining what happened in the reality. Other than that this is our only way of observing it and hence deducing it.
The set of variables and their actual interaction was ‘highjacked’ by the model of spacetime, which is flawed as it misrepresents time. There is no ‘time’ in reality, as it is concerned with the rate at which any given existent state alters. And alteration involves more than one. But only one existent state in any given sequence can exist at a time. So ‘time’ is concerned with change. All that exists in reality is spatial position. Not even dimension, which is just a human simplification of possible direction, that being a function of potential spatial positions available from any given spatial point.

"Cristi has found ways the singularity of a black hole can be transformed away or removed by analytic extension. This is similar to Hawking's imaginary time argument."
It is actually more akin to the Hamilton-Perelman proof that singularities on the manifold of S^3 are extinguished in finite time (Thurston's geometric uniformization conjecture). That keeps the measure space on a positively curved manifold, in the half-open interval [0, oo) and suppresses the role of complex analysis on which Hawking's proposal depends. You and Cristi are going to realize sooner or later that you are betting on the wrong horse.
Paul -- an expanding (and accelerating) universe places the spatial point of creation at ANY arbitrary locus of 3 + 1 spacetime. The point at infinity (in the 4 dimensions of a 3-sphere) is what differentiates Euclidean R^3 from S^3. Philosophizing over existence has nothing to do with the physics -- which is quite straightforward both in the continuous 4-space of Minkowski space-time and the discrete quaternion algebra of W.R.

“an expanding (and accelerating) universe places the spatial point of creation at ANY arbitrary locus of 3 + 1 spacetime”
What is this, but philosophy? If we know reality, as manifest to us, is expanding, then that which it is expanding into is also part of reality. Whether it is currently expanding or not is irrelevant to the location of the start point. Neither does that, or any other factor, mean that that point is at “any arbitrary locus”. If there was such a start, that would have been at a specific spatial position, and that position still ‘exists’. Spatial position does not alter, space does. But space is itself only the corollary of object. That is, there is no such entity as space, only object; space being that which is not the objects under consideration at any given point in time. Whether all possible spatial position is occupied by object at any given point in time, I do not know. But if that is the case then that is just spatial position that is, at that time, not occupied by any object (ie as opposed to just the ones under consideration).
All that is happening is that we cannot know where this original start point is, but we cannot in those circumstances just assert it as being anywhere. Furthermore, your depiction of reality as 3 +1 has no physical validity. There are not 3. There is no corresponding physically existent phenomenon to the concept of dimension. What exists is a definitive number of possible spatial points adjacent to the one currently occupied, ie there are a number of directions in which any given object can move. There is direction, not dimension. That which physically exists and corresponds with the concept ‘time’ (ie +1) is concerned with an attribute (specifically the rate) of change in reality, ie the difference between realities, not an attribute of any given reality.
As I said, a point of infinity cannot exist. It therefore cannot be used as a point of reference. Since we are trapped in a closed system, we can, and must, select any ‘point’ as a reference in order to effect any judgement. Philosophising over anything is pointless. Establishing, logically, how reality physically occurs for us, is not, because that underpins physics. Otherwise it is liable to be based on flawed models which do not correspond with how reality occurs, and hence are just beliefs/ philosophies.

"And in what sense do you say my approach is incomplete? Maybe you can define 'complete' and give some examples, and show how it is incomplete."
The special and general theory of relativity are mathematically complete; every element of the mathematical theory corresponds to every element of the physical observation to the prescribed limit.
"And what 'reversible time parameter' does my 'model' lack? How do you know it lacks it? Why do you say this lack of a 'reversible time parameter' is making a theory incomplete?"
Show that your method of analytical continuation is reversible in the same way as reversal of Ricci flow with surgery back to the singularity, and I will withdraw my comment. Good luck.
"What do you mean by 'reversible time parameter'?"
That the time trajectory backward in time looks the same as forward in time.
"You can reverse the time in any model, by replacing it with -t."
Only if one assumes |t|. In which case, all time intervals are equal. As Leslie Lamport ("Buridan's Principle") has definitively shown, however, every continuous function physical model obviates that assumption.
"Some models are reversible, some are not, but how can the parameter not be reversible?"
When the time evolution of the system is shown to be irreversible.
"Anyway, if you want to know, my models are reversible, unless you redefine the term 'reversible'."
I haven't redefined anything. Until the advent of nonrelativistic quantum mechanics, all physics incorporated a simple time parameter of reversible trajectory.
Cristi, I've not tried to hide my disappointment that Lawrence, whom I know to have expert knowledge of relativity, has bought into quantum models that cannot be completely fit into that framework. I think that if both you and Lawrence honestly investigated the role of topology -- and the leading-edge research in the field that sheds new light on physical phenomena -- you would find as Joy Christian has, that quantum phenomena are in the classical domain, without boundary.

Tom,
You wrote a long reply, but still did not prove your affirmations.
You did not show the relation you claim to exist between my theory and Perelman's proof.
You did not show that my theory is incomplete, and irreversible. You gave as example of a complete theory general relativity. My results are about general relativity, completed to singularities. So how can it be less complete?
You just made some unsupported claims about things you did not check. I tried to understand what you said, and asked you for details for this, but I see now that you made up arguments. As you made up "reversible time parameter" (Google says
No results found for "reversible time parameter".).

No I am not interested in tying JC’s work to this in any way. The notion of locality in QFT is not equivalent to the same term with quantum EPR and Bell’s theorem. JC’s work is not something I have any interest in commenting on further in any way. We have to be honest, that stuff is not going anywhere. The Disproof of disproofs blog section is over 2000 entries, it is too large to conveniently comment on, and I hope there is not a fresh page started for that.

Your post 1/6 09.26 “Mathematics”. Yes, but a system/model which does not correspond with how reality occurs. So, intrinsically it ‘works’ but only in ‘its own terms’, which can be characterised as philosophy.
Here is another example. Take the sentence that Cristi questions above from another perspective. There is nothing but “finite time” (as in timing). If the timing is not finite, then that just means it has not finished. So therefore we cannot know what will occur in this circumstance, because it cannot occur, or be predicted.
Then you post (1/6 09.29) “As are all physical models lacking a reversible time parameter” [which I note Cristi questions] which you explain with (1/6 11.52) “That the time trajectory backward in time looks the same as forward in time”. There is no such thing as a “time trajectory”. There are only occurrences (or better still: physically existent states) at any given point in time (as in timing). [Which is why you cannot have a ‘not-finite time’, because nothing can occur]. By definition, the occurrences happen in a sequence (leaf turns brown, electron spins), which is not reversible. Assuming any given model has depicted the occurrences correctly, and employed the proper relationship between them and timing, then the selection of any sequence of points in time will not ‘affect’ the reality (occurrences). Timing being a methodology for comparing (and hence quantifying) rates of change (which is the physical phenomenon to which ‘time’ corresponds). You may have meant this.

That is what I said, except rather than "meaningless", I characterised it as philosophy, or one could use the description: belief. Science must be objective knowledge (whether expressed in numbers, words, graphics is irrelevant), ie reflect reality 'as is'. And that requires a start point which corresponds with how reality occurs. Reality is not an abstract concept. It exists, for us-but then there is no other form we can know-in a specific physical form as the result of a definable physical process. What occurs at any given point in time, and why, within a closed system, are really what science can establish. Any other form of how, other than that which is a logical truism, is unknowable, because we cannot transcend our existence.

Not so. Anything one says about an existence other than our own is meaningless, because we can only examine reality as it exists to us. There is the logical possibility of other forms, but by definition we can never know them. So the first question, before then establishing what occurred and why within those confines, is to establish, logically, how reality (aka existence) occurs for us (or more precisely all organisms capable of sensory detection).
Our reality exists, it is not an abstract concept. And it does so as the result of a definable physical process. We can hypothecate, in order to overcome certain known limitations of the sensory systems, but this must be on the basis of confirmed sensory evidence. Otherwise it is just belief, because there is no basis for objective validation.

Not so. Because we know that is not how reality occurs. It is independent of the sensing of it. But we can only know it through that process. [Furthermore, hypothecation to overcome certain known practical problems in that process is possible, so long as it is firmly rooted in what has been proven by direct experience, ie it is not philosophy/belief].
"... these metaphysical questions surely lie at the heart of current physics controversy". Absolutely. And a proper understanding as to how reality occurs would resolve it immediately (in the sense of pointing out that the 'controversy' is a function of misconceptualisation, ie two competing and incorrect philosophies. It would not resolve what occurs and why). Because it would point to the flaws in both spacetime and the Copenhagen Interpretation as representative models of that. It would also highlight how Relativity works, though this is clearly stated at the outset anyway, before then being subverted by incorrect thinking, as reified in the spacetime construct.
Neither is it "philosophising" one's way out of the existential conundrum we are in, nor does it "lie beyond scientific method". It is very easy to identify, once one ejects "baggage". We are part of an existence. On what physical basis do we know this? Science, whether expressed in terms of mathematical, word, graphical, representational devices must then correspond with that (eg not deploy a meaning for time which has no physical reality, etc), in order to establish the what and why. There is no choice in the how because it is determined, for us, by our very existence.

"We don't know anything about how reality occurs, Paul. We don't even know IF reality occurs..."
What we do not know, and can never know, is what is 'really' happening. 'Really' being a reference to a logical state that transcends all forms of existence. But by definition, that can never be known by anything, because whenever there is something, then there is always the logical possibility of something else. If A, there is the logical possibility of not-A.
So, rather then get lost in the indeterminable minefield of metaphysical possibilities that result from this existential conundrum, it is important to address the corollary of it. We are trapped in a closed system. We do have the ability to conceptualise 'outside' that, like the Hitchhickers Guide ultimate solution, but this is not knowledge, just belief. To know we must stay within the closed system. The question then becomes how does that occur?
And as Lawrence pointed out some postings back, the train is very real. But as I was pointing out, in terms of the sight mode of sensory detection what is received is not the train but an effect in photons caused by interaction with the train. Very quickly after he feels it!! Etc, etc. Once one establishes the inherent and valid boundaries and then investigates what is physically happening within them, it is very easy to establish, at a foundational level, how it works. On the subject of "we", that includes all organisms, but like many other concepts it gets to torturous to write down all the words. Indeed, reality can only be, for us, all that which is potentially sensorily experienceable by any organism capable of effecting sensory detection. Potentiality there being a reference to known practical problems in the sensory systems. It is also worth noting that that definition includes the potential for a Matian to arrive with a whole new set of sensory capabilities.

Lawrence,
"The general progress of physics has been about reducing the number of degrees of freedom."
Indeed, I very much like the vision you presented in your comment. Reducing the number of degrees of freedom can be viewed as a quantitative implementation of Occam's razor. Of course, like Occam's razor, one should view this as a general indication, and keep in mind that we should apply it with care, that there may be exceptions. For example, in gauge theory, fixing the gauge reduces the number of degrees of freedom. But I think it is preferable to consider the full degrees of freedom as the real structure, together with the symmetries, and to consider the various gauge choices as relative. To reflect this, I would formulate this principle to "reducing the number of independent degrees of freedom" (the key word here being "independent"), emphasizing in the same time the equally important but complementary role of symmetry.
There are several apparently independent indications that a reduction of the degrees of freedom, in the form of dimensional reduction of various types, has a healthy effect on the perturbative series in QFT and even in quantum gravity. Dimensional reduction corresponds, for example, to the vanishing of the Weyl tensor, hence of the gravitational degrees of freedom (including gravitons). This leads to the possibility that dimensional reduction makes quantum gravity perturbatively renormalizable. For some reason, the singularities, which are often presented as a bad thing, undergo dimensional reduction. So this "bad thing" about GR may be
the cure for the other "bad thing", the apparent nonrenormalizability.

As with every other attribute, the deemed ‘degrees of freedom’ must correspond with what occurs in reality, and not be a function of conceptualisation. For example: dimension. There is no corresponding physically existent phenomenon. What does exist is a definite number of possible directions that any given entity can move. That is, from any given spatial position, there are n possible adjacent spatial positions which can be subsequently occupied, at each point in time. Movement being change in spatial position. The concept of dimension is a simplification of this.

Paul,
If I understand well, you consider the notion of "dimension" unphysical, and that it is a simplification of the "number of possible directions that any given entity can move". As being just a simplification, there should be something that is lost during the simplification. What is that? Or was already lost when you said "number of possible directions that any given entity can move"?
Secondly, what is wrong with abstraction? There is no physical entity corresponding to the number 3, since when passing from a set of 3 apples, to the number 3, we further ignore the apples. We learn to count without referring to fingers. We even use fractions without chopping our fingers.
If you look at what you write, you will see that any word you used is an abstraction. None of them corresponds directly to a physical phenomenon, so you can say they all are simplifications.
Now look on the window and see the sky. Do you see the sky, or a simplified image of it, which has so little to do with what is the sky?
Can anyone communicate the real physical phenomenon, and not a "simplification"?

Hi Christi, The EPR paradox is in my humble opinion also one of these problems that we have with our consciousness and the simplification that our awareness is realising. This is the follow up of things : collapse of wave function-signal-senses-observation-brain-awareness-conscious
ness.So there are two steps between the collapse of the wave function and the observation (this takes about 200 milliseconds of processing in our system). So in fact the observation made by a consciouss human being is already in the past compared with cause of collapse. This should mean that this past and the actual observation are entangled ? As entanglement does not need the causal time factor that implements the speed of light, we could be talking about the same kind of "effects". We just simplificate this in the form of accepting that an observation is the cause of the collapse. Is our "reality" also a "spooky" effect of consciousness ?
By the way this will be the subject of my essay.

"QFT is local, but the fundamental (diffeomorphism-invariant) physical observables of quantum gravity are necessarily nonlocal."
This conclusion does not follow, Lawrence. One can only get nonlocal observables by assuming nonlocality -- which makes your version of quantum gravity conform to orthodox quantum theory, only as a sufficient -- NOT necessary -- condition of QFT as an infinitely continuous field.
I know where you're going with this -- to the string theory branch of QFT as a theory of nonlocal hidden variables. There is no physical reason for string theory to be nonlocal, regardless of the widespread belief -- which you here reinforce -- that nonlocality be (mis)taken for physical law.

Hi Wilhelmus,
I think you are right that if the observation causes the collapse, this seems to imply that
it affects the past. The experiment can be arranged to make clear that this extends to much more than 200ms. I don't know if this has something to do with consciousness. On the one hand, I see it as a condition of
global compatibility between our choice and the initial conditions, and this removes the necessity of
wavefunction collapse. We can consider that the initial conditions are delayed until the moment of observation. Although unitary (hence deterministic) also leaves room for
free will*.
Good luck with your essay,

Tom & Cristi,
Cristi: I wrote my long respond to the matter of degrees of freedom below.
Tom: This is a somewhat different meaning to the term locality. Quantum field theory is formulated by specifying field amplitudes at every point on a spatial manifold with clocks synchronized to equal time. QFT equations, such as the Dirac equation iγ∂ψ + mψ = 0 is a partial differential equation that defines an amplitude at every point on the manifold with a coordinate time. These amplitudes on this spatial manifold then commute, or are called equal time commuting fields. This is the meaning of locality in QFT.
This requires a definition of time that is a coordinate time. This runs into a problem with relativity, where the real definition of time is the proper time. In flat spacetime this is dτ^2 = c^2dt^2 – dx^2 – dy^2 – dz^2. The coordinate time t is a matter of a coordinate choice, but the proper time τ is the invariant that is physically relevant. QFT is then difficult to formulate in flat spacetime, where all the machinery I elude to above is needed. For stationary curved spacetime things are more difficult. However, this appears to be a part of the impediment to our ability to quantize gravity.
A nonlocal field theory involves nonzero commutation of fields on a spatial manifold. This is because the manifold is noncommutative and spacetime itself is quantized. The objective then is to replace mention of spacetime or any geometry with algebraic varieties. As for string theory, string theory is in this. String theory has something to do with the physical universe. I am not sure if it is everything as it is sometimes said to be, but it is powerful enough and has analogues now in other areas of physics (solid state physics) to where I think there is some physical element to these structures.

Very sorry I missed that post (30/5 08.12).
Yes, the concept of dimension is “unphysical”, it does not occur. It has no physically existent counterpart. [There were 3 apples]. It is a simplification/ conceptualisation/ generalisation of what does actually occur. Now, there is “nothing wrong” with abstraction, per se, so long as it is recognised as such. But when it is taken as being a correct representation of reality, ie forms a presumption in a maths/graphics model, there are going to be problems. Leaving aside the notion of +1 which is also incorrect, as it is a misconceptualisation of time, there are not 3 [or indeed 7].
Any identification of ‘more’ dimensions in a representational model is based on the incorrect assumption about the starting number and their ‘configuration’. All that exists is a defintive number of possible directions that any given entity can move. That is, adjacent spatial positions, any one of which the entity could ‘occupy’ next. In other words, where the entity is a composite, at the next point in time it could have moved in many of those directions. Or its existent physical state at any given point in time will involve ‘occupation’ of many, if not all, of that potential.
Dimension is a simplication. It reflects a more general tendency to conceptualise reality as ‘its’ changing. That is, ascribe a level of persistence and definitiveness that does not occur. But then the evolution of sensory detection enabled a certain type of entity to utilise existent phenomena and thereby react to their environment, and its development was a function of survival, not understanding what is happening. Which is another way of saying “No(ish)” to you last question: “Can anyone communicate the real physical phenomenon, and not a "simplification"?”. But as they say, ‘two wrongs do not make a right’. Where simplified, that must be in a way that does not contravene the logic of how reality occurs, and it must be considered as a representational simplification and not deemed to be reality.
In respect of a subsequent exchange with Wilhemus. Any form of sensing (including sight) does not affect the reality being considered in any way whatsoever. Not only has that reality occurred, what is subsequently received is not that reality but an effect caused by interaction with it. That effect is, of itself a reality, ie it is physically existent, and it ceases to exist once received. Consciousness has nothing to do with it. We are interested in what is receivable and what instigated that.

“This requires a definition of time that is a coordinate time. This runs into a problem with relativity, where the real definition of time is the proper time”
And herein lies the whole problem. Because really there is only timing. The measurent activity which involves comparison of rates of change. So we can then establish what was occurring at any given point in time, or what occurred between any given points in time. As with any measurement system the units are irrelevant, they are just a common denominator with which to express outcomes, rather than in terms of direct comparson. What is being measured is the rate at which any given physically existent state changes (whether that be manifest in terms of movement, colour, texture, etc, etc, etc). In other words, it would be better if we could expunge the label ‘time’ when referring to what physically occurs, and talk of the frequency with which change occurs. Which can be quantified by a system known as timing.
Once one understands what ‘time’ really physically corresponds with, then it also becomes obvious that that does not occur in any given reality. Because it is an aspect of change (the other being what changed, as opposed to at what rate did this occur), the difference between different realities.

Paul,
You didn't miss it, it was missing, and now reappeared.
I still don't see why saying "number of possible directions that any given entity can move" is more "physical" than using the word "dimension". Why "entity", "move", and "can" which is different from "does" are more physical than "dimension". Or less abstract.
I don't see why you suggest that Lawrence and I ignore that the word "dimension" is an abstraction. We know it is, and we don't need to repeat all the time for each word we use that it is an abstraction.
If you reread the comment you missed, you will see that I consider not only that "dimension" is abstract, but that all our words are.
I don' know how do you know that "the concept of dimension is "unphysical", it does not occur. It has no physically existent counterpart.". How do you know what is physical, and how do you know what "physical counterparts" exist in reality?
Probably you consider "physical" what is more close to what you perceive. I consider this a subjective position, and whatever you call "entity", "direction", and "move" are just internal representations, and abstractions, and should be recognized as such.

‘Entity’. Strictly this is ontologically incorrect, but as with explaining dimension, words can get torturous and very lengthy, unless ‘shortcuts’ are deployed. Entity was just a way of referring to whatever. Really there is no such thing as entity, because at each point in time, there is something different. But, as with dimension, in order to retain our sanity and be able to communicate(!) we conceptualise reality as persistent things. That is, we deem it to be the same thing on the basis of superficial characteristics, and pronounce that ‘it’ has changed.
‘Move’ because this involves change in spatial position. That is how it is manifest. So the ‘something’ (entity/whatever) has the property of ‘occupation’ of spatial position by virtue of its physical existence. And at any given point in time, this has a specific physical configuration. Then there is alteration, and there is a different configuration.
‘Can’ because there are a definite number of possible directions, ie adjacent spatial positions. And the alteration could involve ‘occupation’ of any number of them. If the something is an indivisible particle then it will, by definition only involve one. [Note: the parenthesis indicate that spatial position is conceptual, what actually exists is something].
‘How do you know what is physical’. Because we can sense it, and it is independent of us. So, we have a basis, albeit a closed system, upon which we can know. And while there may be a logical possibility of an alternative existence (ie if A then there is always the logical possibility of not-A), by definition, we can never know this. Science must investigate the potentially knowable. Deliberating about the inherently unknowable (ie not that which involves practical problems-which is why there is the word potentially in the last sentence) is the province of belief systems, as thee are no definable reference points for proof in those circumstances. Another way of putting this is that, reality, for us (which is all we have so the caveat is superfluous) is not an abstract concept. It exists, and does so as the result of a definable physical process.
No it is not what we “perceive”. It is what we (and all other organisms) receive. Unfortunately we can only establish the latter from the former. And then it is important to note, as I have previously, that what we receive is not the reality under consideration, but an effect caused by interaction with it. Colloquially known as light, vibration, noise, etc. These are a reality in themselves, ie they are physically existent phenomena, but in the context of the sensory detection systems which have evolved, they could be characterised as representations. The point is that their existence is independent of the reality, and both are independent of the organism.

Actually, Paul, there are an infinite number of possible directions (degrees of freedom) for a point or point particle, just as there are as many points in this line: ______ as there are in the entire universe.
You confuse people like Cristi and me when you use language so carelessly. If one wants to speak of how degrees of freedom are constrained, one has to carefully describe the constraints.

The important thing about space or spacetime in any dimension is the algebraic system behind it. The algebra is the transformation properties which define the symmetries of the system. Ultimately that is what is most important.

Lawrence, I agree. That is what I have been saying all along -- with the notation that the transformation symmetry is not arbitrary: because any observation is in a bounded length of time, a discrete measure chosen from a continuous range of values is always the middle value. In other words, a binary system implies free will for the observer only by sacrificing the free will of nature, whose length of time for any and all decisions is unbounded. Which means that contrary to Bell-Aspect assumptions, not all time intervals are equal -- for each discrete measure, there is at least one interval in which a decision could have been other than measured.
We can't speak of left hand and right hand algebras, therefore, in coordinate frames of our choosing; a completed measure determines left hand or right hand sides of a coordinate-free geometry, which tells us the symmetry is physically real and not a product of imposing our own coordinates by the axiom of choice, free will hypothesis or other artificial construct.

Lawrence, I expect you didn't see this in the thread that takes too long to load, and I'll edit the example here to purge any reference to that thread. It does deal directly, though, with binary algebras and symmetry:
A continuous range of measurement variables is independent of the discrete output -- i.e., we cannot choose which value the measure falls to, we can only say that it is nondegenerate (nonzero) near the singularity. Suppose one has a kind of constantly spinning roulette wheel imagined to have an infinite number of alternating 0s and 1s, with a window through which we can only see one number at a time: in standard quantum theory, if the observer chooses a 0 at any moment, the window shuts, and every number not shown is a 1. Vice versa if the number chosen is 1. In fact, we could not have even known that the values 0 and 1 were alternating. The observer created the result.
A deterministic theory says that reality is not observer-created. The wheel does not halt nor change ("the moon is still there") when the window shuts. If 0 was chosen, two 1s lie either side, left and right. If 1 is chosen, two 0s lie left and right. In other words, the middle value -- the singularity -- guarantees that identical values are correlated with the observer's choice ALL the time. That's the same result as standard quantum theory, yet rather than an observation changing the numbers, the numbers are correlated because that's the way they were "born," i.e., ordered pairs are guaranteed by the rules of arithmetic, given a binary choice. There's no arithmetic, however, until the choice is made. That's quite a bit different than saying there's no reality unless there's arithmetic (including the axiom of choice), isn't it? In a deterministic theory, arithmetic does not create our choice; our choice creates arithmetic.
An ordered pair refers to a 1-dimensional string, a qubit or a singlet state. The deterministic model adds another dimension (degree of freedom) because the singlet state implies a triplet (0,1,0) or (1,0,1) so we can replace 0s and 1s with the values + 1 and - 1 to get (- 1, + 1, - 1) or (+ 1, - 1, + 1). Point is, because it's the middle value that's always observed, the extra degree of freedom tells us whether the measure is oriented left ( - 1) or right (+ 1).

There cannot be an infinite number of directions for a ‘point particle’. Because it is existent, ie finite. Existence can only occur if there is an indivisible ‘something’ (eg point particle), and that must ‘occupy space’. So its next move (ie alteration in spatial position), by definition, can only involve a finite number of possible directions, which equates to all the adjacent ‘spatial positions’ it could ‘occupy’ next (it cannot ‘miss out’ potential positions, neither can it ‘occupy’ more than one at a time).
Spatial position is not existent, particles (and conglomerates thereof) are. And each occupation of a spatial position is a different physically existent state, of which there can only be one occurring at a time in any given sequence. Spatial position and the occupation thereof, is then just an accurate way of conceptualising what must be happening (hence the parentheses above). In other words, the ultimate unit of spatial position is determined by the size (ie the space occupied) of a point particle. In the same way that the ultimate rate of change in reality (colloquially known as time) is the fastest alteration which occurs.
Tom, I am not using language carelessly. I am using language which has developed, understandably, on the basis of a certain conceptualisation of reality, which is ontologically incorrect. Sensory detection systems are a function of survival. Apart from the fact that capabilities able to receive and process everything probably could not evolve. And neither are the existent phenomena that these systems use probably able to capture and convey everything anyway. So a conception of the world has developed, which works, but does not correspond with how reality occurs.

“because any observation is in a bounded length of time”
Any sensing (observation or otherwise) is of physically specific ‘information’ resulting from an interaction with a physically existent state which occurred at a specific point in time. There can be a sequence of such sensings, which involves the receipt of physically different ‘effects’ (’information’) on each occasion, which themselves arise from different interactions with different (but subsequent) existent states. The elapsed time between the occurrence of a reality and receipt of ‘information’ about it, depends of course upon the speed at which the physically existent ‘effect’ can travel, environmental conditions en route affecting that, and distance between reality and recipient (which is a function of spatial position of occurrence and relative spatial position of recipient to that as at the point in time when the ‘information’ is received). This is all concerned with the timing of events.
“A deterministic theory says that reality is not observer-created”
As per my comment in the thread which shall not be mentioned, and as above. Any form of sensing (observation or otherwise) cannot have any effect on reality. Reality has already occurred, by definition, otherwise it could not be then sensed. And anyway, what is received (sensed) is not the reality. It is a physically existent ‘effect’ caused by an interaction with it. So the only effect sensing can have on any form of reality is it that receipt involves the cessation of the physically existent ’effect’ received. In just the same way, for example, as it would have done had one particular example of the light instigated by some occurrence, hit a brick wall en route, rather than the recipient observer.

In your reply to "Cristi/Tom" you answered to Tom, but not to me. My question was:
'How do you call the "definite number of possible directions, ie adjacent spatial positions"?'
In trying to prove that "dimension" is a simplification of something else, you used in the definition of that "something else" the phrase "definite number of possible directions, ie adjacent spatial positions".
So you only proved that "dimension" is a simplification of "dimension" :)

Sorry, I thought I had covered the point. I was trying to avoid a lot of repetitive posts.
The start point is that there is ‘something’. [We do not need to concern ourselves here with what it is, and can never know how it ‘really’ came about-only how it is as manifest to us]. The presence/physical exisence of that something can be conceptualised in terms of spatial position. In other words, space is not physically existent, only something is. And a something which is indivisible therefore ‘occupies’ one ‘spatial point’. Conglomerates thereof occupy more. Spatial position then alters (ie the somethings move) due to some inherent cause in the somethings.
So, in terms of shape/dimension for a conglomerate something, and movement (ie alteration in spatial position) for an indivisible something, its current/next existent state is a function of the number (which is definite) of adjacent spatial positions it could occupy. [Incidentally, given that each occupation can only occur one at a time, a spatial position cannot be ‘missed out’, each such occupation is a different physically existent state, and something can only directly affect another something which occupies an adjacent spatial position, leads to some interesting observations].
In simple language then, nothing is (ie in terms of that which physically exists at any given point in time) round, square, etc, etc. And nothing has 3 dimensions. It occupies a configuration of spatial points which is determined by the occupation of the points at its boundary, which could be in any one of a number of positions.
You are right to point out that in terms of dimension, which is, as is at any point in time, direction is not involved. Because the latter involves change, ie comparison of two or more. But what I was trying to point out, using language which has developed to depict an alternative, is that there is no physical substantiation for 3. It derives from how sight works, not any logic around how physical existence occurs. Other than it is the minimum number of directions that can be considered in order to depict dimension. Now, that is OK, if 3 is understood as such. But it is not. It is deemed to be a characteristic of reality (the concept has been reified). Worse still, there are then arguments based on flawed models of reality which try to demonstrate it is another number. Whereas, in reality, it can only be a function of the possible spatial points available for occupation, which can be described in terms of the possible directions an indivisible particle could occupy when effecting its next move.

Yes. By definition (ie in order that physical existence can occur, and then alter), this must be so.
Forget any particular ‘thing’ and its properties. If it is a thing, ie has physical existence, then it must ‘occupy’ ‘spatial position’. And it can only be in one physically existent state at a time. [Which involves spatial position, but I would suspect also includes other inherent properties. Spatial position is about what we call size/shape].
As I keep saying, there is no such thing as space, points in space, distance, etc. There are ‘things’. What defines a spatial point in this reality must be that which is the smallest thing. Things cannot be physically existent ‘on top of one another’, ie occupying the same ‘space’ at the same point in time. And physical existence only occurs at a point in time, not spread over a duration of points of time. And what defines a point in time in this reality must be that change which occurs the quickest.

Here is another way of expressing my point.
A ‘point particle’ (ie that which is no longer divisible, forget any other properties and whether by virtue of these there are more than one type thereof) has a size which is one spatial point. Size being manifest as spatial position occupancy at any given point in time. Now, when caused to move (ie alter spatial position) it could subsequently occupy the equivalent of any adjacent spatial position. And so on. So there are n possible directions in which it could next move at any given point in time. And each ‘occupancy’ is a physically different existent state, because there is alteration (put simply, it cannot be the same physical existence if there is more than one position).
When considering a conglomerate of particles, especially if it comprises enough (ie to occupy all the potential spatial positions at its boundary), then the dimensions it actually possesses will be half n. Because the concept of dimension corresponds with spatial positions occupied in a direction (ie point to point). We reduce it to 3 for understandable reasons, but that has no real physical basis. [Incidentally, forget +1. This is nonsense. Physical existence only occurs in terms of a point in time].

Gravity waves are helicity = 2 with two directions of polarization transverse to the longitudinal direction of motion. There is not enough space in two dimensions to put gravity waves or gravitons in. The good thing is there are no problems with renormalization because the whole thing is static.
I and two other physicists have however been working in 2+1 spacetime, where the spacetime is AdS_3, the anti-de Sitter spacetime in three dimensions. The boundary of the spacetime ∂AdS_3 = S^1xR and contains CFT_2. The CFT_2 is SL(2,R)^2 ~ SL(2,C) and contains the Virasoro quantum algebra for string theory. There is a lot here and is difficult to discuss in a relatively short post. I am also reluctant to release the paper in a public manner here at this time. The paper will be ready in about a month.
The CFT_2 gauge theory defines the Hartle-Hawking vacuum, and constructs it from a dimensionally reduced QCD-like theory. The gluon amplitudes can form entanglements which cancel the chromo-charge and give rise to a graviton. I break this out in greater detail in a sort of appendix attached to this post. So the CFT_2 defines the vacuum state of the universe.
The formalism is of nonlocal amplitudes in the BCFW gauge recursion theory. Fundamentally the quantum gravity has no locality, or unitarity. Certain gluon amplitudes have been found to have no local description, and in this CFT_2 construction of the Hartle-Hawking vacuum as in a sense gluon entanglements quantum gravity also then has no local description either. We know that we can functorize space with algebra. On the topological level if something is a homeomorphism then on the algebraic level it is an automorphism. Similarly a compact topology corresponds to unitarity on the algebraic level. The loss of a local description of a QCD-like theory mean there is no time ordering or unitary description. On the topological side this means the space is not compact --- or Hausdorff.
We have in physics lots of experience with quadratic systems, Lagrangians of the form φ^2 or ~ (∂φ)^2. We calculate tangents to geodesics, or intersections and so forth. This mathematically is a typical point-set approach, or a theory of functions on a point-set topology. However, this runs into trouble with non-Hausdorff spaces. The theory must then not be quadratic, but rather cubic. Now we have a theory of the ideals of these polynomials and algebraic varieties. The cubic polynomial is then equated to a quadratic function of the physical fields in an elliptic curve.
The reduction of physics to the algebraic varieties means the point-set data in the standard approach is equivalent to an algebraic variety. This is a vast reduction in the number of degrees of freedom that may be fundamental in the universe,
I attach a diagram of the situation with gauge theory and the section s on a principle bundle P(G). The elements g of P(G) can map s to s’ s’ = gs. So the evaluation of the tangent vector on s’ is d(gs) = dgs + gds = g^{-1}(dg)s’ + 0, where we have chosen ds = 0. Therefore the covariant differential on the section Ds’ = (d + A)s’ is
Ds’ = (d + A)gs = [g^{-1}(dg) + g^{-1}Ag]s’.
This is the transformation of a gauge connection. This is determined on a particular section. A typical choice for ds = 0 is where dA = 0, which is the Coulomb or Lorentz gauge.

We agree, so how can we have the advantages from both theories?
In my view, General Relativity predicts dimensional reduction, but only at singularities. The rest remains the same in General Relativity. I do not propose 2 plus 1 or 1 plus 1 spacetime. This happens only at singularities. But when we quantize, it is known that if at small scales the dimensionality is reduced, QG becomes perturbatively renormalizable.
My suggestion is that the singularities, by their dimensional reduction, also imply this.
So, if a particle is described by a singularity, the dimension is reduced with the distance. But QG needs the reduction to happen with the scale. My argument is the following. The higher energy Feynman diagrams involve more particles in the same region, and therefore more singularities. My singularities have smooth metric and curvature (and I showed that the stationary black holes are like this), and the singular nature manifests by the fact that the metric is degenerate. More particles in a given region means more points where metric is degenerate, so it reduces in average the volume element. The idea is that this regularizes the integrals. I developed this point in the cited paper.
> "I and two other physicists have however been working [...] I am also reluctant to release the paper in a public manner here at this time. The paper will be ready in about a month.
What you said here is very interesting, and I look forward for the paper as well. I will need some time to understand well. I find this place somehow insecure, with comments to which we work hardly being removed like this.

The whole of string theory is on the infinite momentum frame. This is from the invariant momentum interval in special relativity. We have
m^2 = E^2 – p^2
Assume the spatial momentum p = (p_x, p_y, p_z) is such that p_x >> p_y, p_z. We may then write the energy as
E = sqrt{p_x^2 + p_y^2 + p_z^2 + m^2}.
Now factor out p_x
E = p_x sqrt{1 + (p_y^2 + p_z^2)/p_x^2 + (m/p_x)^2}
And us binomial theorem to write
E ~= p_x + (p_y^2 + p_z^2)/2p_x + m^2/2p_x.
We may now rearrange things so that
(E – p_x)p_x = (p_y^2 + p_z^2)/2 + m^2/2
which is on the right hand side a Newtonian (classical) type of Hamiltonian. The p_x for extremely relativistic boost in the x direction is p_x ~= γmc. This means p_x serves as a Lorentz factor and the left hand side is the total energy multiplied by this factor.
A particle which falls onto a black hole as seen from the outside experience a sequence of Lorentz boosts so that v = sqrt{g_{rr}/g_{tt}} --- > c. The external observer then witnesses the relativistic motion time dilated to extremely slow time intervals so it appears nonrelativistic. It further occurs on a plane that is transverse to the boost direction, which in the case of a black hole is the event horizon. This Hamiltonian is used to construct the string Hamiltonian or Lagrangian, and in a funny way this form reduced to a nonrelativistic setting is then equivalent to the sort of wave equation such as the Klein-Gordon equation.
An observer that is stationary with respect to the black hole must exert an acceleration g to remain on that frame. Only as the distance from the black hole goes to infinity can g -- > 0 and the stationary frame of this observer is preserved. An observer very close to the black hole must exert a huge acceleration. The time dilation of the exterior world as detected by such an observer means all quantum field that enter and quantum escape the black hole are blue shifted. Hence in the limit g --- > ∞ the event horizon approaches a UV divergence. By way of contrast the freely falling observer continues to witness fields on the stretched horizon (a Planck unit of distance from the horizon) in the IR field spectrum. However, this observer will enter the black hole where the Weyl tensor diverges. This is a UV divergence in the limit r -- > 0 (Schwarzschild) or r -- > r_- (Reissner-Nordstrom), which is then identical to the UV divergence witnessed by the highly accelerated observer.
The highly accelerated observer will witness fields or strings on the event horizon annihilated in the emission of radiation from the black hole. This is complementary to the infalling observer who witnesses fields and string demolished by the interior singularity. There should then exist by this complementarity a way the infalling observer can transform to a “frame” where the interior singularity in the UV divergent configuration is shifted to an IR field configuration. The compression of dimensions with the observation of fields on an event horizon then should be analogous to such a dimensional reduction in the interior. The dimensional reduction on the horizon puts all of the relevant dynamics on the directions transverse to the boost direction. The case with the interior singularity is more subtle, and I suspect the spatial dimension that is restricted is replaced with some dimension in “quantum space,” such as direction in a Fubini-Study metric. Your previous work is suggestive of some sort of analytic continuation, where if the imaginary part is some phase e^{iφ} for φ the interval on a Study-Fubini metric on projective Hilbert space we are then eliminating a spatial or spacetime dimension and lifting the system into “quantum space.”
This seems to hinge around the issue of the Weyl curvature. If spacetime is reduced to 3 dimensions where the C_{abcd} --- > ∞, the data is then transferred into quantum bits or lifted off spacetime.

Lawrence,
Thanks for this interesting exploration of the possible connections with the holographic principle. I plan for some time to study the connections between singularities, horizons, and the boundaries at infinity. There are many connections between them, but I want to understand the fundamental principle behind them.
I think you are right about the complementary frames in which an observer reaching the singularity can be viewed. As in the case of the event horizon, there are frames in which the Weyl tensor is divergent, and frames in which it is smooth. For example, while for a
Schwarzschild black hole, in Schwarzschild's coordinates C_{abcd} is divergent, there are coordinates in which g_{ab}, R_{abcd} and C_{abcd}
are smooth (while g^{ab}, R_{abc}^d, C_{abc}^d are divergent, but we can express the equations in terms of the good quantities only). In the case of the event horizon, Schwarzschild's coordinates are singular on the event horizon, and the Eddington-Finkelstein are not. Similarly at the singularity, there are singular coordinates, in which g_{ab} is singular, and regular coordinates, in which it is smooth (although det g=0, and the singularity still exists, but it is tamed, in the sense that we can write Einstein's equations and other field equations there, by using
a generalization of the covariant calculus which works for degenerate metrics too). In fact, C_{abcd} ---> 0 at the singularity in these coordinates.

Hi Wilhelmus,
I think you are right that if the observation causes the collapse, this seems to imply that
it affects the past. The experiment can be arranged to make clear that this extends to much more than 200ms. I don't know if this has something to do with consciousness. On the one hand, I see it as a condition of
global compatibility between our choice and the initial conditions, and this removes the necessity of
wavefunction collapse. We can consider that the initial conditions are delayed until the moment of observation. Although unitary (hence deterministic) also leaves room for
free will*.
Good luck with your essay,
Cristi

Observation only causes the cessation of a specific effect in photons (known as light), which in the context of the evolved process of sensory detection, is the physically existent phenomenon that is received by the observer. It results from interaction with an 'event'(existent state).
There is no physical connection between detection and the event. Apart from which, that event occurred before receipt of the light, anyway. So observation, or indeed any other form of sensing, can have no effect whatsoever on reality.

Perelman’s proof of the Poincare theorem on the equivalency between fundamental groups π^1(S^3) and topology of S^3 relies upon the Ricci flow of Hamilton
∂g_{ij}/∂t = 2R_{ij} + ∇N_j + ∇N_i
where the sphere is a case with nonzero Ricci tensor. With vacuum solutions we are interested in R_{ab} = 0. The Weyl curvature in four dimensions for a type D solution is eigenvalued by the Killing vectors K_a
C_{abcd}K^bK^d = λK_aK_c
A typical Killing vector is of the form K_t = sqrt{g_{tt}}∂/∂t which in the Schwarzschild case for r -- > 0 diverges. So the divergence of the Weyl curvature is directly dependent on the divergence of the Killing vector field. Then say for K_φ = ∂/∂φ
C_{tφtφ}K^φK^φ = λK_tK_t
The reduction of a dimension though means if the Weyl tensor vanishes, this is equivalent to g_{tt} -- > 0 for some cut off in the curvature where the vacuum solution fails at the singularity.
There is then something analogous to the Perelman “renormalization” of the Ricci flow. However, in this case the three dimensional manifold “flows” in an ADM type of relativity with a diverging Weyl curvature. Perelman’s proof is a technique for “rounding off” the cinching of a manifold region that is approaching a cusp. For the Weyl tensor case the region of integration does not include the singularity, but where that region is distorted into a filament along the longitudinal direction, or “spaghetti.”

Tom,
I like your messages. You began to add more explanatory material. I am thinking now that your strong balance between understanding the physics and math is what makes your messages helpful. I am not referring to just the math of Joy's model or of Bell's Theorem. I mean that you have a broad understanding of mathematics, especially where it becomes abstract.
It seems that I get directed to sources for Bell's Theorem's math or perhaps veiled suggestions that Joy's math should be evaluated as if it were a variation of Bell's Theorem's math. I don't worry about the correctness of the math. There has been ample guidance on how it is to be applied. I think the real test is that either the model will be accepted by the physics community or it will not.
I expect that for those who are strongly familiar with the physics and math terms, visualizing Joy's model is not difficult. I was hoping there would be more discussion about visualizations of the model for non-professionals. Developing such a visualization is what I am working on.

Thanks, James. I think it's ironic that while those in the know do allow -- as Scott Aaronson did in his blog -- that one indication of the strength of a mathematical model is its flexibility in translation to other forms and applications. Yet when when shown those forms and applications, they are most often stubbornly resistant to consider, much less accept, them.
In mathematics, the adage seems to be that unfamiliarity breeds contempt.

Regarding Joy's model,
What I see happening is that the critics argue that the math shows obvious error. When the response is that the model dictates that the math must be manipulated differently from the method used by the critics, the critics stick with their insistence that the perceived error is too obvious to be itself in error. What is missing from the critics' arguments are direct responses to the model itself. The physics is not sufficiently addressed even by physicists. The math cannot tell the true story without being concretely interpreted along with the interpretation of the model. The physics does come first.
If critics don't agree with the reasonableness or correctnes of the model, then that is where they should begin their case. Argue the model, add the math to it, evaluate the correctness of the math as it pertains to the model. If it is an accurate representation of the model, then the matter is to be settled by theoretical physicists. However, even while not accepted, if the model fits empirical evidence and if the math fits the model, then the model is valid theory. Whether or not the model is a valid interpretation of the nature of the universe is for theoretical physicists to debate.

Hi James,
Ultimately, the matter has to be settled by a certain experiment. Joy's model is definitely validated by the EPR-Bohm type quantum experiments so the critics have only the math to criticize which as you say above is wrong. You are definitely right about that. However, Joy contends that his model also applies to a more "macroscopic" realm (non-quantum) and that test of Bell's theorem has never really been done. I agree and a real test of Bell's theorem should be done.
Best,
Fred

Thank you for adding that your message.
I do understand the importance of the experiment. I have mentioned that in earlier messages. I neglected to emphasize it in my last message. It should have been included there. It is the experiment that should take the debate out of the purview of theoretical phyhsicists.
I do think that experimental physicists will first evaluate the model for themselves. If it fullfills the requirements of agreeing with empirical evidence and being correctly represented by the math, then even doubters among experimental physicists should appreciate the importance of testing Joy's theory by performing the experiment. The possibility of establishing continuity between quantum physics and relativity physics is important enough in itself to justify the experiment.

well, it seems that the irony continues unfortunally. In fact I can understand that the advisory council needs a credibility.Unfortunally the sciences are not a play for an ocean of pseudo publications. In fact sometimes I beleive that several confounds what are the sciences and its rationality, and on the other side the sciences fiction and its irrationalism. The philosophy, the universality, the sciences are in a pure objective road where the physicality possesses precise and irreversible law. So why they try to insert bizare correlations and exotical things inside this physicality. That has no meaning in an universal axiomatization of universal laws.
In fact you try to interpret a thing totally unknown because we are inside this physicality and its walls. The SINBGULARITY , the central sphere and the singularities at the cosmological and quantum scales are codes RATIONAL .So why they try to insert pseudo derivations or extrapoplations or interpolations...just because several parameters must be considered and unfortunally they do not insert them, unfortunally still. The rule and the responsability os an institute like FQXI is to be rational and not in the publicity of members and friends of the council. If now, the sciences are in this optic, so it is very sad for our future and the interactions between the scientists. This kind of comporment is not really an accelerator of evolution, and don't say me that it is the free will.The free will ok, but of course when we speak of sciences, we must respect several universal evidences, the relativity is there also. If now we are on a platform for the publicity of strings, extradimensions and parallel universes, so where are we going, and all that just for the vanity and the monney and the pseudo free will.I don't understand this comportment.Mr Tegamrk, you are an intelligent person, so why?

Hi James,
One area on which Richard Gill and I agree is that a mathematical model must be independent of experiment. I'm in a rather difficult position defending Joy's framework, because he started out by alienating -- and this is no exaggeration -- every mathematician on the planet ("disproof"). It's a huge irony, because it's the mathematicians, brought up on theorem proving, who would naturally ally themselves with a creative coherent argument if they have or can acquire the background to understand it. Physicists couldn't care less; physicists as a rule take mathematics "off the shelf" and try to fit it into what they are doing experimentally (whether real or gedanken). The job of a mathematician is to create new mathematics.
That's the rub. We can't create "new physics." We can only explain the physics we have. So a physical theory is tested by measured correspondence of a phenomenon against its mathematical explanation. That's what makes quantum mechanics so successful; it is vulnerable, however, to being the victim of its own success. That is, if the mathematical theory were completed, it would not be coherent -- how do we know this? -- because quantum theory at any scale is not coherent without the assumption of nonlocality. Mathematical completeness cannot be compatible with nonlocality, either mathematically or physically.
Einstein stood by his philosophy, "I am not interested in this or that phenomenon, in the spectrum of this or that element; I want to know His thoughts -- the rest are details." In this respect he thought like a mathematician rather than a physicist. Completeness is what the "Old One" imagines. Relativity is mathematically complete in the classical domain.
Believe me, there are many days when I wished I hadn't signed on to this dispute. I've got my own program. And even with the overlap, the distraction is taxing and wasteful of my time. If we are going to be intellectually honest, though, we cannot dismiss arguments that are inconvenient, or that lie outside the rules we have prescribed for ourselves.
When we create new mathematics, we have to be ready to change or reinterpret some rules. When it's complete, *then* we can speak of how it corresponds to the "real world," a physical experiment. Otherwise, we are merely cobbling up explanations for what the real world *appears* to be telling us -- and that doesn't guarantee that we really got the true message (hence, Joy's "illusion of entanglement")and usually, we are simply validating what we already know to a reasonable certainty. A mathematically complete explanation that predicts an unexpected outcome, OTOH, has much greater explanatory power.

Excellent message. I am unclear about this statement:
"Mathematical completeness cannot be compatible with nonlocality, either mathematically or physically."
I understand it to be saying that: Since relativity theory is mathematically complete, and, since quantum theory is not, that it is assumed that quantum theory must evolve into a state where it can be absorbed into a fuller theoretical framework dominated by relativity theory.

Well put. It's that, yes, but more:
Mathematical language, despite its reputation among many unfamiliar with it, is not mystical. It's built of definitions and theorems rather than bricks and mortar, yet the abstractions are every bit as solidly joined as the best-built dwelling. Imagine that a builder invites you to view your new house from a hilltop. You look down and see a foundation hole, a rickety frame, a partly finished wall, a crumbling chimney. "We're making progress," he says. "When will it be completed?" you ask. He looks puzzled, "What do you mean?"
"When can I expect to live in it?"
"Oh, you can't ever live in it. Wouldn't be safe."
"Excuse me?"
"We don't know when something might collapse."
You are incredulous. "Don't you have plans, drawings, blueprints, specifications?"
"Sure." He hands you the plan. It's an exact copy of the wreck you see below.
"But this doesn't tell me what the house is supposed to look like!"
"Of course it does," he says. "What do you see in the plan that's different from what you see below?"
He's got you there. You can't argue with success.
"That's pretty ugly," you say.
Again, he's puzzled. "Is there some law that says a house has to be pretty?"
You admit, "I suppose not."
"Well, then can you take care of this bill for the progress we've made so far?"
"It's in the mail," you say.

Tom and James,
Aren't His plan and His creation of an evolution rather self-reflecting assumptions on which a lot of theory rests? I recall sarcastic comments which compared mathematics with a building without a solid basis. Indeed, mathematics works well without Cantor's naive set theory. The fundamental crisis of mathematics has been overcome by sitting it out. I read Rosa Peter's "Das Spiel mit dem Unendlichen". She did not get aware of Cantor's basic mistake. As you Tom already found out, we may retrace the issue back to Cauchy. Do you know D. Spalt?
Already Spinoza rejected genesis, and he defined infinity something that cannot be enlarged. I disagree with Einstein who wrote in 1932: "The most beautiful and deepest experience a man can have is the sense of the mysterious." My basic assumption is more parsimonious: logic reasoning including the distinction between causes and the effects that they precede. Einstein's SR is probably based on mistakes made before him.

Hi Eckard,
As you know, I regard relativity as settled science. I expect you'll find some agreement with James over "... the distinction between causes and effects ..." while I think continuous causality is sufficient to explain discrete effects. This is inherent in Lamport's continuous range of measurement values and in Joy's model of continuous measurement functions.
I think it's pretty obvious that I strongly agree with Einstein's view of life's mystery. In fact, I think we can measure scientific progress in direct proportion to our capacity to be surprised by our results.

Tom,
Concerning relativity you are in the comfortable position to hide behind dominating tenets. The also considerable list of opponents offers diverse and mutually excluding variants of criticism rather than just one alternative.
However, I disagree with your argument that "continuous causality is sufficient to explain discrete effects". Let's consider one chosen point time in the ongoing history of a continuous measurement or an other ongoing process. Given all measured so far values belonging to it are know to us. In that sense they are continuous. Nonetheless, the values after the chosen point of time are quite different from the values before it because we may exclude that they did influence anything before the chosen point of time. The difference cannot be found in the laws of nature. It belongs to the actual limitation of influences.
When the late Einstein admitted that the now worries him seriously, he suspected a mystical explanation outside science.
He was definitely not too stupid as to understand in what he was simply wrong. He did just by no means accept putting relativity and space-time in question. When Popper commented "you are a Parmenidean", Einstein did not object. This philosophical twist went along with his readiness as a believing physicist to accept mysticism.

Hi Eckard,
"Aren't His plan and His creation of an evolution rather self-reflecting assumptions on which a lot of theory rests? ...
... Einstein's SR is probably based on mistakes made before him."
I communicate with others, when there is good reason to believe that they know what they are talking about. No matter what I may think for myself, it is essential that I understand what they think and why. I think Tom is a far greater talent than is recognized. I think his ability to bridge formally between physics and math is something that I should learn more about. I have learned, from communicating with him, that there are things that I have stated in the past that were probably not clear to others because I use the same words too loosely.
For a recent example I said: The mathematics must be fitted to the model. I now recognize that I should make clear first that the model cannot corrupt what mathematician's have created. Rather, it must make use of those parts of math that serve its purpose. By making this concession, I am not doing what I cannot properly do and that is to vouch for the correctness of math. You see potential problems in math that I am taking into consideration because you have brought them to my attention.
I usually speak of cause and effect as separate properties. That is because they are identified in mathematical equations as separate properties. Also, it is convenient to speak about them separately. However, there is no separation between cause and effect. If there is cause then there is effect. I suppose it is even possible for one to philosophize that one could speak of effect and cause. Not that effect proceeds cause but rather it would be a recognition that cause does not proceed effect. They are simultaneous properties.
I do think there is too much mystery left in achieving our understanding of the operation of the universe to think that we know much at all. Our foundational science is about mechanical activity. Since the universe gave rise to intelligent life, I consider it to be self evident that the mechanical perspective is minor at best and even possibly misreprentative of the true nature of the universe.
With regard to physics theory: I will preceed what I have to say by first recognizing the great academic accomplishments of experts in the field. I wish I knew as much as they do. However, my opinion is that theoretical physics contains error that goes all the way back to our interpretation of mass. I am sure that you have seen me say this several times before.
I also see several errors made after that: electric charge, thermodynamic entropy, the constancy of the speed of light, and perhaps most importantly time. I mention time in that special manner because I found that there is a universally constant measure of time and that that value, when incorporated into denominators of rates of change with respect to time, is the single biggest contributor to achieving unity.
I must qualify everything that I have said here with the admission that I am not a theoretical physicist.

“When the late Einstein admitted that the now worries him seriously”. Then that was most likely because of the way that which exists and is referred to as time, and timing, were confused. Which was then reified in the model spacetime, which was supposed to be a logical consequence/explanation. But is not. The original papers are clear, and rational, the whole hypothesis depending on the presumption of length alteration in the line of motion.
As you say in the paragraph above that sentence, now, ie what is physically existent, is only definable as at a point in time (as in timing). Timing is not variable. Time is, but only when one properly refers the concept to the physically existent phenomenon which prompts its conception, ie the rate at which any given physically existent state is superseded by the next in a sequence, which manifests as alteration.

While I see cause as well as effect belonging to objects that we consider to exist even if they might sometimes not be clearly defined, a wonder if you can give an example for a concrete cause that is its own concrete effect.

I am having difficulty seeing that we are talking about the same thing. I would not make the statement that 'There is a concrete cause that is its own concrete effect.' With regard to Moebius strip and Klein's bottle, you must know more than I do because I do not understand how cause and effect applies to them. They are abstract mathematical concepts for me.
Theoretical physics may draw upon such concepts in order to lend mathematical support to its own abstract concepts, but, since I did state in an earlier message that I think errors began with theoretical physics right from its beginnings, I also think that the need of theoretical physics to resort to including strange distortions and mathematical convolutions results from the acceptance of earlier fundamental errors.

Let me consider an example. A cyclist might consider it counterintuitive if he feels wind, that is blowing exactly from the side, coming a bit from in front of him no mater whether he is cycling in forward of backward direction. I do not consider his fallacy correct common sense (in German sound mind). I call it a rather common while easily explainable naive mistake. Such naive mistake was made by Cantor and even worse, it was declared the putative solution to a puzzling while already by Galileo correctly answered question. On what was Cantor's reasoning based if not on the seemingly compelling conclusion that there must be more real numbers than rational numbers because there is no bijection between them, in other words if there are not less reals than rationals and also not equally many then there must be more reals? I am calling this type of reasoning a common while easily explainable naive mistake. Its implications forced even proponents like Fraenkel and von Neumann calling Cantor's set theory naive. Hilbert meant having rescued it by hiding the mistake within a bundle of clever designed axioms.
So we may hope for the day all science is again done by common sense in its best meaning, unaffected from naive rigor of modern mathematics. If the outcome of an experiment does not agree with what was expected from a theory then I see this an indication of a flaw no matter whether in the experiment, in the theory, in both, in the expectation or of interpretation. Knowledge can merely be confirmed to some extent by means of objectivating application of ultimately sound (common) sense. Perhaps you know places where many dispensable crutches are believed giving evidence to miraculous healing. Do you refer to this kind of objective knowledge?
Strictly speaking, seemingly reversible processes, in particular oscillations and rotations, are idealizations in so far they are directed and always embedded in irreversible ones. The earth will never rotate backward.

You certainly know the metaphor of snake that is eating its own tail. Concerning Klein's bottle see http://en.wikipedia.org/wiki/Klein_bottle#Properties: It is "a surface in which notions of left and right cannot be consistently defined". Unlike the Möbius strip, the Klein bottle is a closed manifold, meaning it is a compact manifold without boundary. While the Möbius strip can be embedded in three-dimensional Euclidean space R3, the Klein bottle cannot. It can be embedded in R4, however.
Yes, above mentioned snake incidentally illustrates what you wrote: "Theoretical physics may draw upon such concepts in order to lend mathematical support to its own abstract concepts, but, ... I think errors began with theoretical physics right from its beginnings". When did theoretical physics begin?
You further wrote: "I also think that the need of theoretical physics to resort to including strange distortions and mathematical convolutions results from the acceptance of earlier fundamental errors." What kind of errors do you refer to?
I see the ambition to formally justify obviously fertile pragmatism.
I also recall the reasoning of the Pythagoreans: The border is the essence of an object because while an area can be without a body cannot be without surface. Hence, the area is more important than the body, the line is more important than the area, and the point is more important than the line.

Maybe, maybe not. What we know, though, is that if it *couldn't" rotate on the opposite trajectory, our equations describing Earth's motion would not be reliable, because there is no *physical* reason to prefer one direction over the other. There is no sense to speak of reversible processes embedded in irreversible processes; positive feedback, e.g., has no forward or reverse -- it's a continuous loop, acausal.

"Yes, above mentioned snake incidentally illustrates what you wrote: "Theoretical physics may draw upon such concepts in order to lend mathematical support to its own abstract concepts, but, ... I think errors began with theoretical physics right from its beginnings". When did theoretical physics begin?"
In my opinion, it began with f=ma. The equation when first written down says that there is object acceleration implying there is cause identified as force. The acceleration varies in a manner that makes clear there are varieties of resistance to acceleration called mass. My position is that at this point the equation is not theoretical. It becomes theoretical when mass is arbitrarily made an indefinable property. Please see below.
"You further wrote: "I also think that the need of theoretical physics to resort to including strange distortions and mathematical convolutions results from the acceptance of earlier fundamental errors." What kind of errors do you refer to?"
Quoting from my message to you of June 5th: "With regard to physics theory: I will preceed what I have to say by first recognizing the great academic accomplishments of experts in the field. I wish I knew as much as they do. However, my opinion is that theoretical physics contains error that goes all the way back to our interpretation of mass. I am sure that you have seen me say this several times before.
I also see several errors made after that: electric charge, thermodynamic entropy, the constancy of the speed of light, and perhaps most importantly time. I mention time in that special manner because I found that there is a universally constant measure of time and that that value, when incorporated into denominators of rates of change with respect to time, is the single biggest contributor to achieving unity."
Narrowing the problem down to a specific kind of general error: The error is the practice of arbitrarily making properties into indefinable ones. The only two naturally indefinable properties are distance and time. An indefinable property is one that cannot be defined in terms of pre-existing properties. Its units cannot be defined in terms of pre-existing units. The decision to make mass an indefinable property was the first error of this type. Mass should have been defined in terms of the pre-eisting properties of distance and time.
The reason why I say that this is the case is that empirical evidence consists of measures of distance and time. All properties of physics must be expressible in the terms of the empirical evidence from which their existence was inferred. The damage done to physics equations through the arbitary practice of inventing indefinable properties shows up in the use of their arbitrarily assigned indefinable units.
There is a second kind of error. It is the error of misinterpretation. An example of the second type is the assumption of the constancy of the speed of light.

Tom,
The physics of motion and Cantor's set theory are connected via the changed by Bolzano, Cauchy, Weierstrass, and others notion of number. You will hopefully agree that there is no justification for integration from minus infinity to plus infinity if one intends to analyze measured data because in reality, future data are definitely not available.
I would like to add: Future motion can only be calculated for sure if all belonging future influences are available. This would be equivalent to a shifted border between past and future, in other words, with no future to be taken into account.
When I tried to restrict to mere past, i.e. replace IR by IR+, the mathematicians were unhappy and not in position to decide how to deal with the number zero in this case. They told me that Weierstrass and others introduced a putatively rigorous redefined notion of number. David Joice confirmed my guess that The good old Euclidean notion of number was indeed abandoned. A rather comprehensive textbook, I forgot the Spanish sounding name of its author, celebrates this development as important success. My essay 833 offers a way out.
If you do not understand my examples, I will try and explain they more in detail. The mistake of the cyclist is obvious: He adds forces instead of velocities which are to be squared for calculation of the force.

“The only two naturally indefinable properties are distance and time”.
I do not know whether these are the "only two". And I would advocate the use of different labels, because those have additional connotations. Distance corresponds with spatial position. Any given ‘entity’(which is all we have) ‘occupies’ a definitive spatial position at any given point in time, wrt any other given entity. The underlying presumption in Relativity is an alteration in dimension (ie space occupied) when force is applied, which if correct complicates the concept of distance. And we only know of ‘entities’. So really the property is spatial position ‘occupied’ by these, at any given point in time.
Time corresponds with the rate at which one reality (existent state) is superseded by another. It is an attribute of change, not any given reality, per se. This can be assessed by comparing rates of change, and is called timing. Hence the use of the caveat “at any given point in time”-as in timing-above. So really the property is rate of change wrt any given attribute of any given entity.
So, reality is a sequence of existent states, with all that comprises any given state occupying specific spatial position. Something is causing these existent states to alter. The rate at which they do so (which could be in respect of different attributes) is colloquially known as time.

A very simple way of expressing what I said above is: there is something, and it alters. That’s it.
The something has spatial position, both in terms of what it ‘occupies’ and hence in terms of its spatial position wrt to some other something. There is alteration. But something can only be something once. Alteration means that another something has superseded the original one, and it has done so at a rate.
This is not belief. Just the way it must be, for us. And as I have said to Tom above, that is all we can know.
On the subject of whether there are “only two naturally indefinable properties”, I said I do not know. You assert there are. Personally, I would think there are not. Because alteration is caused by something, which would seem to indicate at least another such property, as spatial position and rate of alteration will not suffice.

Really? So it is just me is it that thinks there is 'something' and it alters? Which, as I said is an alternative and simple way of expresssing what I wrote previously. Which then determines what is spatial position and the physical phenomenon that corresponds with the concept known as time.
I do not understand your comment about length contraction. This has nothing to do with the essential point I am making. It was just to highlight a supplementary issue with the concept of distance, assuming of course, there is validity in this hypothesis anyway. Neither was it incorrect, just a repeat of what Lorentz, et al, said. For example, here is just one quote: [Lorentz 1892 para3] "Such a change in length of the arms in Michelson’s first experiment, and in the size of the stone plate in the second, is really not inconceivable as it seems to me".

“Paul, What do you mean by 'dimension'? as in both "...an alteration in dimension (ie space occupied)" and "...it reverts to its ‘normal’ dimension."
I take it that this is the direct question your refer to in your first sentence, having then copied out parts of other posts, which I know anyway.
I presume you are reading other posts. Because while I do not want to be accused of not responding to you, I do not want to repeat all that I have just written elsewhere, some of which is already repetitive.
Dimension is a false concept, but in this context I am repeating what Lorentz, et al, said. And anyway, that does not have any bearing upon, essentially, what they were saying. Indeed, I even put the words “space occupied” after dimension.
Anyway, the straightforward answer to you question is, I do not mean anything, because I am not saying anything. I am repeating what they said. And they came to the conclusion that matter really alters shape when caused to change momentum. They also presumed that it had a natural shape, ie when ‘at rest/in equilibrium’. [I will refrain from pasting quotes to substantiate these statements]. How this mechanism worked was unknown, and they said so, postulating several different explanations over the years. But the concept was never withdrawn. It got subverted when the effect was explained using an flawed understanding of the variables and their relationship. In simple language, time became the surrogate for dimension alteration.
The hypothesis of dimension alteration was physically real. It had nothing to do with measurement, observation, light, or whatever. Remember, it was originally about the eletrodynamics of moving bodies, none of these other things. And the concept of relativity was just a statement of the obvious, it was not a central point. By definition, what happens in reality must be explainable from any reference (a law must hold). But that presumes that one knows the state of that reference. And they were postulating that an alteration occurs, which was previously unknown. So, in order to make judgements, one needs to ensure what is involved is comparable, or have established the difference and then accounted for it. And, according to them, objects with changing momentum were also changing in dimension, because something else caused both of these effects.

In fact, it (I assume you mean length contraction) has everything to do with *all* these. Because the speed of light is constant, and therefore independent of an observer's state of motion, the measurements that various observers make in their own relativistic reference frames -- of which none is privileged and all are valid -- determine the effect of contraction, which appears different for different observers. In other words, the recorded observations -- measurements -- are relative to the observers' respective states of motion and not absolute.

I am not sure what you are really asking me anymore.
Lorentz, et al, postulated that the dimension/length/shape-or any other word one wants to deploy-altered. The point is not about a specific word, but about the nature of the event. And that was that the entity physically altered. It was not a point about measurement.
Again I will just post one quote, but there are many others. Lorentz 1892: “that the line joining two points of a solid body doesn't conserve its length, when it is once in motion parallel to the direction of motion of Earth, and afterwards it is brought normal to it… Such a change in length of the arms in Michelson’s first experiment, and in the size of the stone plate in the second, is really not inconceivable as it seems to me”.
The hypothesis is that matter has a certain state, which apart from anything else is manifest in the ‘space’ any given entity ‘occupies’. [Note my posts in a thread above]. When a differential force acts upon the entity, then it is 1) caused to change momentum, and 2) caused to occupy a different configuration of space (ie change shape). When the forces are subsequently counterbalanced, then the entity regains its original shape (ie spatial occupancy). Matter has a certain elasticity. Note the words: “brought normal to it”. This concept is repeated elsewhere with the notion of ‘at rest and ‘equilibrium’. Incidentally, this is why I tend to refer to alteration, because although the references are to contraction, by definition, and they said so anyway, there must be a ‘de-contraction’ (effectively expansion).

It was the conclusion drawn, and therefore the effect which needed explanation. However, very shortly after, with a confusion over how the variables involved interacted, it became something else.
The original wrings were not about light, and hence observation. Because, as you say, light travels at a constant speed. So it was not the ‘problem’. And anyway the concern was about the electrodynamics of movement, not the observation of it. As per the 1905 postulate: 1) light always starts at the same speed, 2) will continue at that speed unless impeded. Both of which are correct, because 1) light is the result of an atomic interaction which therefore results in the same outcome (ie it is not the consequence of a’collision’), 2) as with any other entity, all will continue at a speed unless impinged upon.
BUT. Calibrating that speed, as with any such attribute, must involve comparison, ie a reference to and the establishment of difference. There is no absolute available. And since light is just another entity, which is travelling, its calibrated speed will differ with the reference, which is just another travelling entity. That is, it is only “constant” in the sense that the original start speed is always the same irrespective of circumstance, and it is independent of any given observer, or indeed any other entity. Observers are not some form of ‘different’ entity, they just happen to be able to utilise that light if they receive it.
On this basis then, quite correctly, a result was expected from M&M. But it did not occur. Hence the shape/dimension alteration (length contraction) hypothesis. Now, whether the outcome of the M&M experiment substantiated this conclusion is another matter. One has to note that in 1916, whilst accepting that the effect occurred, Einstein said: “the expected difference is much too small to be noticeable in the measurement of earth's surface”. Whether the effect actually occurs is yet another issue.
As you say, and as I have said above, the measurement made within each observer reference is valid, intrinsically. But that does not alter reality (ie extrinsically), which is what they said was happening. This ‘observer reference’ cause is a subsequent, and misconceived explanation as to what may, or actually may not, be occurring. They did not say, ‘this effect is the result of individual perception’. It was not a theory about observation. The word ‘frame’ tends to get equated with observation perspective, when actually it is just a point of reference. Which one must always have when effecting a judgement. Which as you, and they, said, must be any reference. In simple language, ‘it cannot work only from selected reference points’.
And the significance of ‘state of motion’ has nothing to do with observation. According to the hypothesis, if an entity has a changing state of motion then it also has a changing shape, because there is one factor that is causing both effects. Remember, an observer is just another entity, so it too will be changing shape, ie light will take ‘longer’ to reach it in the sense of: than would otherwise have been expected. Their point was, before it all became confused (though it may not be correct) is that altering motion was an indication of altering shape. So, beware. Because comparison depends on comparing like with like, always using the same reference (once chosen), and factoring in any known changes. But if you are not aware that the shape of an entity is changing then your calculations will be wrong. Because the corollary of entity is ‘space’ (distance between entities being considered)) and that will alter as entity alters.

“the relative state of observer motion is the *only* parameter that informs us of the true physics of a given measurement”
Not so. A differential in motion is a factor if matter alters length as its motion is caused to alter. And even then, calculations could be effected, they are just more difficult. It is not the differential of motion, per se, but what is supposedly happening (ie length alteration). All we have are lots of things (including the reality under consideration, light, observer) which are moving, either at the same constant rate wrt each other, or different constant rates, or variable rates. If the latter is occurring, then the argument is, the matter involved is altering in length. Because there is something else causing both, ie a force-gravity. It has nothing to do with observation. Different relative configurations of reality/observer will render different results in terms of measurement. Obviously. [Indeed, note that different environmental conditions in which light travels could also render different results for different observers]. But we do not suddenly then declare that the reality occurred in n different sizes, or colours, or whatever. Reverse engineering from these, based on a physical understanding as to how it all works, allows us to extrapolate what originally occurred (ie reality, the physically existent state). It was not a theory about the observation of the electrodynamics of moving bodies, but a theory about how that occurs.
“all your arguments assume a privileged rest frame of observation in a context which allows no such privileged frame”
Not so, quite the opposite. Any judgement, whether it be about speed, colour, texture, noise level, etc, etc, involves a reference. It must do. And the point is, as a statement of the obvious (relativity), that this can be effected from any point of reference. Movement of everything in the universe could be gauged against the snail currently moving across my garden. Impossible practically, but logically correct. But having selected any given reference from all those available, then one must adhere to it, so that all other judgements are comparable. What they were saying was (originally, before it all got confused): ‘hang on a minute, changing motion indicates a circumstance where alteration in length is occurring. Now we did not know this before. So, in order to make correct judgements, one must be aware of this and factor it into the calculations’.
Section 18 (SR & GR 1916) is particularly revealing, once unravelled, and the concepts are repeated elsewhere:
“If it is simply a question of detecting or of describing the motion involved, it is in principle immaterial to what reference-body we refer the motion. As already mentioned, this is self-evident... Our principle…can also be expressed as follows: For the physical description of natural processes, neither of the reference bodies…is unique… Unlike the first, this latter statement need not of necessity hold a priori; it is not contained in the conceptions of ‘motion’ and ‘reference-body’ and derivable from them; only experience can decide as to its correctness or incorrectness…The validity of the principle of relativity was assumed only for these reference-bodies, but not for others (e.g. those possessing motion of a different kind). In this sense we speak of the special principle of relativity, or special theory of relativity. In contrast to this we wish to understand by the "general principle of relativity" the following statement: All bodies of reference are equivalent for the description of natural phenomena (formulation of the general laws of nature), whatever may be their state of motion. But before proceeding farther, it ought to be pointed out that this formulation must be replaced later by a more abstract one, for reasons which will become evident at a later stage”.
Now add on an excerpt from section 28:
“In gravitational fields there are no such things as rigid bodies with Euclidean properties; thus the fictitious rigid body of reference is of no avail in the general theory of relativity. The motion of clocks is also influenced by gravitational fields, and in such a way that a physical definition of time which is made directly with the aid of clocks has by no means the same degree of plausibility as in the special theory of relativity”
This reveals the differential between SR & GR: ‘motion of a different kind” is involved, so too is gravity. The latter being deemed to be both the cause of “motion of a different kind” and the lack of rigidity in bodies. BUT. As of really when the first paper was written, the variables have become confused (Poincare is a culprit, but the establishment of the flawed model spacetime sent it all awry). Time, and then observation, have taken over as being explanations of the variance (which was originally an actual physical alteration in shape of matter under certain circumstances). We now have the nonsense, in attempting to invoke an explanation from a false perspective, of that effect translating into an outcome in clocks which will proportionately affect their ‘tick’ rate. No, they might just contract and cease functioning altogether, or whatever! And a clock is not time, it is just a device for effecting timing. One does not need a clock to do this. Timing is the comparison of the frequencies at which change occurs. One can do this directly: the sea rose n mms whilst the albertross flew n miles. The phemenon which corresponds with the concept of time is: rate at which any given change occurs. [Note: change does not exist, existent states occur. And there are differences].

Yes. Obviously. In fact, so obviously, that I did not presume that was your question. I mean, I did actually quote the original words, And used the word ‘dimension’ in something I labelled “simple translation”. So I do not think there is any question as to what I meant when relaying what they said. And incidentally, the original post was to Pentcho, not you, and neither was it “teaching” anybody.
It does not matter what word is used in this context. Because the point being made was that they hypothecated that matter physically changed, NOT that the effect is in observation, or something to do with timing, ie some form of ‘illusion’. Specifically what (allegedly) occurred, etc, etc, is detail, and there is a danger that people will get lost in that, eg arguing over what constitutes ‘length’, there is only ‘contraction’, or whatever, rather than taking on board the main point that, supposedly, matter has some form of elasticity.

“The only two naturally indefinable properties are distance and time”.
I do not know whether these are the "only two". And I would advocate the use of different labels, because those have additional connotations. Distance corresponds with spatial position. Any given ‘entity’(which is all we have) ‘occupies’ a definitive spatial position at any given point in time, wrt any other given entity. The underlying presumption in Relativity is an alteration in dimension (ie space occupied) when force is applied, which if correct complicates the concept of distance. And we only know of ‘entities’. So really the property is spatial position ‘occupied’ by these, at any given point in time. ..."
Your teaching message was aimed at me. That quote at the top is my words. Your message went on to teach me more of your incorrect knowledge.
"It does not matter what word is used in this context. ..."
It matters a great deal. Your 'simple translation' is in error. "Simple translation: matter alters dimension in the line of motion when the rate of motion is caused to alter, and once the cause ceases it reverts to its ‘normal’ dimension. [The cause was subsequently attributed to gravity]."
So, when you quote the words "'normal' dimension", you are simply saying that the length has returned to its original state?

It was not a “teaching” message. You were previously quoting a post in response to Pentcho. This post was a response to a post of yours, ie I did not suddenly decide to post it. And the word ‘dimension’ and the point about it, was a supplementary point anyway to my main point, ie ‘if their hypothesis is correct then that further complicates matters’. As indeed I said in a follow up post when you raised this, rather than concentrating on my main point. It is instructive to note that Tom just said: ‘I presume by that you mean length contraction’ and then got on with explaining why he thought I was incorrect.
The word does not matter, contrary to what you just assert. Because, as I said, but I will repeat, the point is not about precisely how matter alters, but that it does. Then one goes on to investigate how, why, etc. The emphasis being to debunk the subsequent interpretation that it is to do with measurement, observation, time, etc. As they did not say this.
Perhaps, eventually, you will try to substantiate what this “incorrect knowledge” is, or where my simple translation is in “error”. Rather than just making these assertions, in amongst spurious points.
The answer to your last question [ie “So, when you quote the words "'normal' dimension", you are simply saying that the length has returned to its original state?] is Yes. Obviously. That is what they said, and I quoted it. Indeed, I am not quoting the words ‘normal dimension’. The specific quote was: Lorentz 1892 para 3 “and afterwards it is brought normal to it”. Apart from the fact that this is obvious, otherwise matter would just get smaller and smaller. There are other quotes elsewhere which revolve around the notion of ‘at rest’ and ‘equilibrium’. Frankly, I expect people to go back to the originals (or at least translations thereof) and check 1) is this a correct quote, 2) is it being attributed with the meaning that they had, or are the words being placed out of context, 3) are there other such quotes, or looking at all that was said then, which substantiate the point.

So the quote Lorentz 1892 para 3 “and afterwards it is brought normal to it”. is saying "...that the length has returned to its original state". Do I have that right?

Yes.
For example by 1904, he has a different view of the mechanism involved (though he always admits that he does not really know):
“I shall now suppose that the electrons, which I take to be spheres of radius R in the state of rest, have their dimensions changed by the effect of a translation, the dimensions in the direction of motion becoming kl times and those in perpendicular direction l times smaller”
Note the concept “state of rest” (elsewhere “equilbrium” is used). This is the same as “brought normal to it”. That is, once the forces acting upon it are counterbalanced (ie irrespective of their magnitude), then matter assumes its natural state in terms of size (and one particular aspect thereof, ie length in the line of motion).
Just for the record. A few weeks before Einstein’s paper (July 1905), Poincare had to introduce some compensatory actions/forces (they were given a name which I cannot remember off hand) in response to criticim of this latest explanation of the mechanism from Lorentz, from someone who’s name I also cannot remember off hand.

I don't see where the application of a force is said to cause length contraction. But you are saying that a full understanding of "brought normal to it" means that the object is brought to rest, or a state of force equilibrium, by removing or balancing the forces acting on it, and that the removal or balancing of force allows the object to return to its full length? Is that it?

Yes. They were saying: if there is a changing rate of motion, then length is also changing. This being because there is a common cause, which is a differential in force encountered. There is always force, so it is an imbalance thereof which instigates the circumstance. The concept of “at rest” (or “equilibrium state”) referring to when the object is in a constant state of motion, ie it is neither being caused to slow down nor speed up. In which case it will be at its natural size, ie neither contracted nor elongated.
The mechanism involved was at first deemed to be an effect on “molecular forces” caused by motion through the ether, then that became spherical electrons being “flattened ellipsoids” by electromagnetic fields in the ether. Now, whether the mechanism proposed was correct or not, is irrelevant in that this was just an explanation for an effect which was deemed to occur (ie length alteration). And the force deemed to be causing this was gravity. Here are some quotes to substantiate that (you questioned where it said that):
Einstein: SR & GR, 1916, section 18, para 5: “…provided that they are in a state of uniform rectilinear and non-rotary motion…The validity of the principle of relativity was assumed only for these reference-bodies, but not for others (e.g. those possessing motion of a different kind). In this sense we speak of the special principle of relativity, or special theory of relativity”.
Einstein: Foundation of GR 1916, section 3: “…the case of special relativity appearing as a limiting case when there is no gravitation”.
Einstein: SR & GR, 1916, section 28: “In gravitational fields there are no such things as rigid bodies with Euclidean properties; thus the fictitious rigid body of reference is of no avail in the general theory of relativity”.

Paul,
I guess I didn't make it clear that I did not see references for either applying force or removing force or any consequences of force in the Lorentz quote. My main interest had to do with ascertaining Lorentz's meaning of the word 'normal' and your meaning and comparing the two. Force is not the cause of length contraction. Lorentz's use of the word normal pertains to the orientation of the object. That ends my questions. Thank you for your time.

That is a really peculiar reply. I supply various quotes and clarifications. You then just assert: 'no it is not, it means something else'!
According to them:
1 Force (gravity) is the cause of length alteration
2 The concept of 'normal', and indeed length alteration which results in not-normal, has nothing whatsoever to do with orientation. The alteration just occurs in one direction, ie line of motion.
Lorentz 1892: "Such a change in length of the arms in Michelson’s first experiment, and in the size of the stone plate in the second"
Lorentz 1892: "Indeed, what determines the size and shape of a solid body? Apparently the intensity of molecular forces; any cause that could modify it, could modify the shape and size as well"
Lorentz 1892: "A contraction of the diameter of the Earth by this ratio would amount 6 cm"
Lorentz 1895: “…when (during the rotation of the apparatus) sometimes one, sometimes the other arm would have the greater length…Consequently we have to imagine, that the motion of a rigid body, e.g. a brass rod or of the stone plate used in later experiments, would have an influence on the dimensions throughout the aether, which, depending on the orientation of the body with respect to the direction of motion, is different…”
Lorentz 1904: “I shall now suppose that the electrons, which I take to be spheres of radius R in the state of rest, have their dimensions changed by the effect of a translation, the dimensions in the direction of motion becoming kl times and those in perpendicular direction l times smaller…Our assumption amounts to saying that in an electrostatic system, moving with a velocity, all electrons are flattened ellipsoids with their smaller axes in the direction of motion”
Poincaré (July) 1905: An explanation was proposed by Lorentz and Fitzgerald, who introduced the hypothesis of a contraction undergone by all bodies into the direction of the motion of earth”
Einstin Foundation GR: "The unit measuring rod appears, when referred to the co-ordinate-system, shortened by the calculated magnitude through the presence of the gravitational field, when we place it radially in the field...Thus Euclidean geometry does not hold in the gravitational field even in the first approximation, if we conceive that one and the same rod independent of its position and its orientation can serve as the measure of the same extension. But a glance at (70a) and (69) shows that the expected difference is much too small to be noticeable in the measurement of earth's surface...The gravitational field has no influence upon the length of the rod, when we put it tangentially in the field"
Etc, etc, etc

It is essential, when enterring into a discussion with you, that I focus the subject. I chose as the focal pint the word normal. Learn my correction to you on that point first. There is no doubt about the meaning of the word normal as used by Lorentz in that quote which I was discussing. You need to check that out and understand its meaning. Its meaning pertains to the orientation of the object. It is more specific in its meaning than that, but, I left it unfinished so that I would know when you learned its specific meaning. You clearly still have not checked it out.
Length contraction is not caused by force. Your past explanations about it had to do with busses and poles moving parallel to the Earth. The gravity situation must wait until you understand length contraction without gravity.
In the meantime you are misinforming others. Fortunately for me, I understand more than enough to not be fooled by your statements. You are certainly free to post your messages without my correcting you. I ask that you not continue to attempt to correct me with your incorrectness. Learn what that use of the word normal means.

Apart from the fact that it is dangerous to attribute a meaning on the basis of one sentence, and there are plenty of others which, in context as well (some of which I have quoted), substantiate what I said they were saying. Let’s have a look at the quote anyway:
Lorentz 1892, para 3: “It consists of the assumption, that the line joining two points of a solid body doesn't conserve its length, when it is once in motion parallel to the direction of motion of Earth, and afterwards it is brought normal to it. [The difference when comparing the two motions in the same dimension being p2/2V2] . Such a change in length of the arms in Michelson’s first experiment, and in the size of the stone plate in the second, is really not inconceivable as it seems to me”.
The phrase “line joining two points” is a somewhat awkward expression”, but relects the paragraphs above and below this. The alteration is occurring in one particular dimension. Orientaion of the object, as such, is irrelevant. Normal is the dimension occurring when there is nothing affecting it.
You then assert: “It is more specific in its meaning than that, but, I left it unfinished so that I would know when you learned its specific meaning. You clearly still have not checked it out. Length contraction is not caused by force”.
The question there would be, well what causes this then, according to them. Leaving aside the fact that they actually tell us.
You then assert: “The gravity situation must wait until you understand length contraction without gravity”.
Really? But there is no length contraction without gravity! Einstein said so:
Einstein: Foundation of GR 1916, section 3: “…the case of special relativity appearing as a limiting case when there is no gravitation”. & Einstein: SR & GR, 1916, section 28: “In gravitational fields there are no such things as rigid bodies with Euclidean properties; thus the fictitious rigid body of reference is of no avail in the general theory of relativity”.
However, perhaps then you would like to explain what they said about length contraction in a circumstance where there is no gravity. Bearing in mind that Einstein defined that as SR (which is not the same as all that which was written in 1905):
Einstein: SR & GR, 1916, section 18: “the special principle of relativity, i.e. the principle of the physical relativity of all uniform motion. … It was at all times clear that, from the point of view of the idea it conveys to us, every motion must only be considered as a relative motion. As already mentioned, this is self-evident… provided that they are in a state of uniform rectilinear and non-rotary motion…The validity of the principle of relativity was assumed only for these reference-bodies, but not for others (e.g. those possessing motion of a different kind). In this sense we speak of the special principle of relativity, or special theory of relativity. In contrast to this we wish to understand by the "general principle of relativity" the following statement: All bodies of reference are equivalent for the description of natural phenomena (formulation of the general laws of nature), whatever may be their state of motion”.
& Einstein Foundation GR, section 1: “According to the special relativity theory, the theorems of geometry are to be looked upon as the laws about any possible relative positions of solid bodies at rest”.
& Einstein 1916 (Foundation) Sec A sub section 1: “The word "special" is meant to intimate that the principle is restricted to the case when K' has a motion of uniform translation relatively to K”
Etc, etc, etc.
In other words (in accordance with what Einstein said, not what Paul Reed thinks), SR is a hypothetical circumstance where there is no gravity, with objects that retain their shape, light that travels in straight lines, only uniform rectilinear and non-rotary motion, and Euclidean maths is applicable.
Paul
Incidentally, I cam across these two quotes, whist checking for others:
Einstein: On the electrodynamics of moving bodies, 1905, section 4: “A rigid body which, measured in a state of rest, has the form of a sphere, therefore has in a state of motion, viewed from the stationary system, the form of an ellipsoid of revolution with the axes…..Thus, whereas the Y and Z dimensions of the sphere (and therefore of every rigid body of no matter what form) do not appear modified by the motion, the X dimension appears shortened in the ratio 1: √(1-v2/c2), i.e. the greater the value of v, the greater the shortening”. [Note here the reference back to Lorentz’s latest explanation of the mechanism-electrons and flattened ellipsoids]
Einstein: SR & GR, 1916, section 12: “It therefore follows that the length of a rigid metre-rod moving in the direction of its length with a velocity v is √(1-v2/c2) of a metre. The rigid rod is thus shorter when in motion than when at rest, and the more quickly it is moving, the shorter is the rod”.

What has a dictionary got to do with it? The point is to understand what they were saying. And it is clear from that paragraph alone what was meant. Taking into account other paragraphs it is unequivocal. Whether they were correct, is another matter, but that is what they meant. Normal refers to the size (and hence some form of state of which that is a function) of a particular dimension Ie the one in the line of motion). Which under a certain circumstance is altered (ie it contracts) and then when that circumstance ceases it reverts back (ie it elongates wrt the contracted size)to the normal size. The alteration in size means that the 'state' of the object has been disturbed, it is no longer at rest/in equilibrium. A differential in force incurred has occurred, and that force was deemed to be gravity. The theory was about the electrodynamics of moving bodies.

I choose the problem of reviewing BASIC assumptions based on "thermodynamics of steady state" ideas of my 1959 research advisor, Dr. Ralph Tykodi* (now deceased) and personal experiences as a marathon swimmer.
In particular, the definition of energy as being associated with only that which we can easily measure and relate to, i.e. mechanical. Thermodynamics relates it to heat (based on temperature) and work (of many forms). Both of these relate to processes which involve chemistry (endo- and exo- thermic processes) and life (something that accomplishes something).
It will take some time and I may not succeed, but I presently see a way out of the macro (gravity) and micro (charge) complications of relativity (classical) and quantum (probability) that physics tries to define and measure.
In short, the the basic assumption of - what energy really is- needs updating

It does tend to take one into the realm of the metaphysical and the conflicts between two accepted approaches, science and religion.

In 1993 in my second year of my BA in applied Science university in Amman-Jordan, I had a big question, it is how I can understand the special relativity theory according to the concepts, principles and laws of quantum. From that time till 1996 I found, the error was in the concepts and principles that Einstein adopted in the special relativity theory which were depending on the classical theory. One of these problems was the constancy of the speed of light, and then the reciprocity principle. And in order to unify between quantum and relativity in concepts, principles and laws, relativity theory must be modified according to the concepts, principles and laws of quantum. I completed this modification in 1996 and this was my graduation research. I remember when I discussed my research in a seminar, I told the presented students and doctors " according to my new relativity which is agreed to the concepts, principles and laws of quantum, it possible measuring the speed of a particle or electromagnetic wave to be greater than the speed of light, and in this case time is speeding up". At that time, my teachers have not believed me, and told me it is impossible to do that, and experimentally it is required hard working abilities to proof that.
Since the weakness of the abilities in the Arabian universities, my theory remained on hold in my university library. The experiments done by Gunter Nimtz in 2007-2008 regarded to quantum tunneling were good proof for what I proposed in my MSRT. Furthermore, the OPERA, Icarus, and SN1987a can be interpreted by my modified special relativity theory. Here I display the link of my modified special relativity, it is in http://vixra.org/pdf/1111.0001v1.pdf
The philosophical aspects of the theory existed in http://vixra.org/pdf/1206.0002v1.pdf Furthermore I could solve the Pioneer anomaly exactly according to modifying the relativity theory http://vixra.org/pdf/1109.0058v1.pdf Also quantum entanglement can be interpreted by my theory. Finally I hope to take my chance in FQXI.org to display my work to public after 18 years working. I'll not be angry if I'm wrong in my modified relativity, because I'll know the right. What I need now to be sure if I'm right or wrong. I hope to take my chance for discussion my MSRT.

I'm all in: and this time will continue to develop the Theory of Consciousness according to Young's Double-Slit Experiment, this time re-deriving C according to NOT X^2=X. Recall this is the equation that represents Boolean Logic: it's how we think and how we program computers to think. This will hint at the goal of incorporating the Measure problem into a Quantum Gravitational Theory. Then I shall use the footnote from that same essay to further develop the equation for Asimovs' 3 Laws of Robotics (which equations are posted in my previous Essay. Further developing this Theory of Consciousness, and solving some long-standing problems in Physical Theory currently unsolved. Will wrap it up with a lucid caution to cease and desist all particle-accellerator experiments immediately, and why. Last and least I shall address our Physical Assumptions currently, and which are paths to discovery in this new Science. And suggest experiments and data in current exps. that can prove the new Theory of Reality posed in the New Essay Entrant. Or I shall not even enter, because getting a job and an income-stream is more important. It's a digital-computer toss. p.S. The last essay has also resulted in a website that sells all auto parts anywhere 24/7 through our official partner Advance Auto Parts stores nationwide.

Oh, and just in case you are deleting the essays and threads from the last contest let me re-Publish that equation for consciousness here?
Before continuing, let us simplify things a bit by letting HS=C, where C is consciousness (whatever that means in an experimentally testable sense). So this equation then means: the human soul is consciousness. Well maybe or maybe not. We will save that Theory until experiment can decide the validity or no... Maybe the soul is much more than consciousness. But surely a part of the soul is consciousness? Even if not, for the sake of brevity, let us assume that all human souls have consciousness. Then
C=a(1-P)(1-D)(1-O)+b(1-P)D(1-O)+PDO {1}
and
0=P(1-D)(1-O) {2}
and
0=PD(1-O) {3}
Interpretations:
{1} consciousness is sometimes a wave that is not observed whether detected or not, and is always the result of an observation of a detection of a particle.
{2}and {3} If a particle is not observed, whether detected or not as a particle, it does not exist. It is a non-real, virtual, wave until it becomes actual.
Thanks, look forward to the Essay Entries!

I've already participated twice in the FQXi-Contest. It was always a great opportunity to present ideas that would otherwise be rejected. I am currently working on an essay which is closely related to the ongoing discussion. It concerns the speed of light.
We know that light itself has a dual nature, which we are usually calling the "wave-particle-duality". I am convinced that the speed of light is of dual nature as well! In other words: The speed of light is also a quantum mechanical property that is given twice.
Accordingly, it is geometrically codified in two different ways - as a circle (= wave) and as a square (= particle). Since both geometric matrices are closely entangled and parameterized in the same way, that is, c = 1, it is extremely difficult to recognize this dual nature of the speed of light.
Seduced by the principle of relativity, we ask only whether the parameter c = 1 is empirically realized in nature or not - without knowing that c = 1 has two faces and not only one as we still believe.
Since this parameter c = 1 has been confirmed again and again, we came erroneously to the conclusion that Einstein's special theory of relativity is a fundamentally correct theory about the universe, but in truth we have been deceived by nature, especially by its quantum mechanical core.
This is the story I want to tell in my essay.
But to be honest, it's more a vision than a theory

Brendan,
In the criteria it says essays should be new thinking on the author's part and not pet theories packaged with a few nods to the topic. I think a point I have been making here for years; That we treat time as a vector from past to future, because we experience it as a series of events, is mistaken and that it is the changing configuration of the extant, turning future into past, which goes to the core of the confusion permeating physics. So would this be an acceptable topic, even if I've already beaten it near to death?
While I may not have much to add to points I've already made, I do think it is something worth broader consideration.

FQXi Administrator Brendan Foster replied on Jun. 14, 2012 @ 20:41 GMT
Hi John -- First answer is, it's up to you as the writer to decide whether the material merits an essay or not. Now for the long answer, let me have a good cup of coffee===
I think you're hitting on two connected, but subtly different points--'originality' and 'topicality'.
On originality, I would say it is probably to be expected that an author would focus on a specific theme on which they have already spent some time thinking or writing. But, ideally, the author would honestly push themselves into new territory with the essay. In the past, we've seen winning essays that didn't put forth a whole new research result, but at least presented older results from some new perspective.
report post as inappropriate
FQXi Administrator Brendan Foster replied on Jun. 14, 2012 @ 20:51 GMT
And on 'topicality'--well, we want people to honestly think about and try to answer the question, Which Assumptions...
That's where the line about pet theories comes in. In some sense, any new work in physics challenges old assumptions, but I would say that a good essay will not be about a particular theory--it will be about those assumptions challenged by the theory. It will explain and argue why those assumptions have to go. There are various 'preferred frame' theories out there, for instance [as I know well]--but a topical essay won't just present such a theory--it will argue why we need any such theory in the first place, why the assumption of no-preferred-frame is wrong.
In closing, though, these are just my thoughts, and as always, the winners are chosen by a combination of votes from lots of people who may feel differently from me. And you as an author may choose to disagree too.

Nested PHASERS Invented as Proof of the Holographic Principle (or Who Watches the Watcher)
Tommy Gilbertson
QuantumWidgets.com
Abstract: PHASERS (Probability Hamiltonian Amplification by the Stimulated emission of Radiation) are invented and briefly explained to propose an experiment whereby a unique reality among the multiversal copies of the experiment is chosen consciously by the experimenter, i.e. the outcome of a probability-distributed range of eigenvalues of an observation occurs more often than 75% of the time in a large number of identical experiments, where the Standard Model predicts a range of outcome probabilities instead. This process will be explained by proposing a new form of field of Consciousness (using previous work by the author) whereby the messenger particle is a quantum of ‘conscious’ thought. This theoretical prediction of the future experiment described will be used to show that some of our fundamental assumptions about physical reality are mistaken, and a way forward theoretically and experimentally is briefly described, proposed using existing newly invented technology from the TED community. Then the essay shall diverge sharply, and transmute into a plea to focus science solely on the problem and a proposal to help immediately stimulate the economies of the world. On which economies all of our theories, experiments, inventions, and freedom of thought therefrom, depend essentially.

This essay contest is a bit depressing. In the software development world, anyone, even a kid, is free to post a bug report--it's easy to do so, with no formality. If the bug is serious and is shown to be reproducible, other people will listen. The bug may then get fixed. In the physics world, "bugs" are hard to report (a sound argument is insufficient; a subjective level of "extraordinary evidence" is only part of the requirements) and any amateur physicist who posts one is automatically assumed to be a crackpot, such that there's no need to read the bug report. (I'm not talking about indisputable observations, like those through a telescope. Of course those can upend our knowledge. I'm talking about mistakes in our theoretical physics.)
I'd love to write an essay for this contest, if I thought it would be read. But I'm confident it wouldn't be. I don't mind writing something short like this though, in the event there is a truly curious & open mind out there. Google for Solutions to 5 Major Problems in Physics. One of our basic physical assumptions that is wrong is that general relativity is consistent with its equivalence principle postulate for every small freely falling frame that GR allows. The inconsistency is in plain sight, is provable by a short/unique sound argument, but it's subtle.

Well, I didn't mention rather obvious inconsistencies. If they were obvious then general relativity would be recognized as invalid already.
The stats on my blog confirm the unlikelihood that an essay by me would be considered by the FQXi editors. Unfortunately the state of things today is this: while a teenager can be hailed for finding a subtle and serious problem in widely used software, only the annointed few are permitted to challenge widely accepted physics, regardless of proof. Everyone else is a crackpot by definition. To give the appearance of openness, however, anyone will be allowed to present proof, which is then ignored.

I find one note in your rules a bit confusing. I do have a "pet theory to trot out," and it does "reject assumptions" of established physics. That might seem to disqualify me, at least if I read the note in one particular way.
However, I have performed well-documented experiments supporting this “pet theory” – experiments that I plan to describe in detail. In other words, I do offer “new insights” about “tacit, unquestioned assumptions.” Therefore it seems to me that the note warning against “pet theories” does not disqualify me – at least, not out of hand.
Right?

Hello Eric -- as a working rule, we don't look to disqualify an entry based on content. We want to leave it to readers and referees to decide how well the essay honestly addresses the topic. The Community has done an excellent job at this kind of filtering in the past.
So, one way to look at that note is as tested advice on how to write a successful essay. Every piece of good science challenges assumptions in some way. What though is more interesting to a reader? An essay mainly focused on the features of a "pet theory" -- Or an essay focused on why familiar assumptions cannot stand, which uses a pet theory as an illustration?
That subtle shift in emphasis has had a huge impact on the success of entries in the past.

As an example, people should check out Jarmo Makela's
first prize winner from last year.
The main content is essentially a summary of Jarmo's viewpoint on how quantum gravity should be constructed -- in some sense, a 'pet theory'. That technical content, though, is immersed in a larger, more general discussion of whether spacetime is discrete [the contest topic]. The specific theory almost seems to emerge as the "obvious" choice [to Newton, I guess], based on the bigger discussion. The essay is a lot of fun, but also persuasive and possibly even subversive.

Which bit of Jarmo's proposition do you say is 'obviously wrong'
The consistency of Newton's; "all states of motion are the same and stay constant unless a force is applied (giving acceleration)."
with the STR's;
"all inertial (non accelerative) frames are equivalent"
Which of course it seems to be, as the second can be derived directly from the first without changing any of it's meaning.
Or are you saying you believe both are wrong?
I suggest perhaps you simply never looked at Newtons 1st Law in that way. Perceptions do vary, and are everything, as Bragg said; “The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.”

Jarmo's suggestion (put in Newton's mouth) that "the idea of the constancy of the speed of light with respect to all inertial observers" is deducible from the Newtonian theory is obviously wrong. Newton's emission theory of light says that the speed of light as measured by the observer varies in accordance with the equation c'=c+v, where v is the relative speed of the emitter and the observer.

OK, but haven't you also just put words on Newtons mouth? Your interpretation is again 'consistent' with c plus v, so is valid, but can you point out where he actually SAID it in that way? Logically both Jarno and your interpretations are similarly valid.
I indeed agree with emission at c, in every possible case, including all absorption and re-emission! But speed is only of course 'real' when using 'Proper Time'. i.e. If the observer is in a different medium (a space ship) and state of motion, then a pulse 'passing by' would be apparently doing so at c plus v, which is because the observer is moving at v. It would only of course be doing c locally in the medium it is IN. Fresnel's 'n' is a constant, even if it's 1, as in diffuse plasma and the IGM. Do you disagree n is a local constant?
Do you also disagree with Bragg? (A different way of looking at it is needed).

ews_on_the_Composition_and_Essence_of_Radiation
Albert Einstein (1909): "A large body of facts shows undeniably that light has certain fundamental properties that are better explained by Newton's emission theory of light than by the oscillation theory. For this reason, I believe that the next phase in the development of theoretical physics will bring us a theory of light that can be considered a fusion of the oscillation and emission theories."
The emission theory was extremely successful by the end of the 18th century but then completely forgotten:
http://www.ruhr-uni-bochum.de/wtundwg/Forschung/tagungen/OWR
_2006_10.pdf
Jean Eisenstaedt: "At the end of the 18th century, a natural extension of Newton's dynamics to light was developed but immediately forgotten. A body of works completed the Principia with a relativistic optics of moving bodies, the discovery of the Doppler-Fizeau effect some sixty years before Doppler, and many other effects and ideas which represent a fascinating preamble to Einstein relativities. It was simply supposed that 'a body-light', as Newton named it, was subject to the whole dynamics of the Principia in much the same way as were material particles; thus it was subject to the Galilean relativity and its velocity was supposed to be variable. Of course it was subject to the short range 'refringent' force of the corpuscular theory of light --which is part of the Principia-- but also to the long range force of gravitation which induces Newton's theory of gravitation. The fact that the 'mass' of a corpuscle of light was not known did not constitute a problem since it does not appear in the Newtonian (or Einsteinian) equations of motion. It was precisely what John Michell (1724-1793), Robert Blair (1748-1828), Johann G. von Soldner (1776-1833) and François Arago (1786-1853) were to do at the end of the 18th century and the beginning the 19th century in the context of Newton's dynamics. Actually this 'completed' Newtonian theory of light and material corpuscle seems to have been implicitly accepted at the time. In such a Newtonian context, not only Soldner's calculation of the deviation of light in a gravitational field was understood, but also dark bodies (cousins of black holes). A natural (Galilean and thus relativistic) optics of moving bodies was also developed which easily explained aberration and implied as well the essence of what we call today the Doppler effect. Moreover, at the same time the structure of -- but also the questions raised by-- the Michelson experiment was understood. Most of this corpus has long been forgotten. The Michell-Blair-Arago effect, prior to Doppler's effect, is entirely unknown to physicists and historians. As to the influence of gravitation on light, the story was very superficially known but had never been studied in any detail. Moreover, the existence of a theory dealing with light, relativity and gravitation, embedded in Newton's Principia was completely ignored by physicists and by historians as well. But it was a simple and natural way to deal with the question of light, relativity (and gravitation) in a Newtonian context."

Excellent quotes. So you agree, both Jarno and your interpretation are equally valid (by inference) and consistent, if not using Newtons own words.
And can I assume you agree then that n is a constant, in which case light must always changes speed on re-emission to the local c (or c/n) of the co-moving media?
This implies a separate kinetic based speed change, to meet local relative v, over and above that to meet relative n. That is new. Is it visible to you?

Hi John -- I'll make a note of that info. But also just to clarify, the purpose of the reviewer info on the entry form is just to give us an idea of who you think qualified experts are for your essay. That information collected from all entrants helps give us a sense of the range of people we need to find for the panel. We may not actually contact any of the suggested reviewers -- or we might contact them. We also don't select specific people just to read specific essays--the review panel has to consider all the essays.

FQXi Administrator Brendan Foster replied on Jul. 6, 2012 @ 15:53 GMT
So anyway, the point is, we may or may not contact Julian Barbour for the panel, but it is useful to know that you would call him qualified to review your essay.

Of course I should have thanked the whole FQXi team, sponsors and those who are taking part. It can be quite a emotional time when first trying to get some recognition of your achievements, yes. I like to think I'm used it now with my second contest entry completed and hours spent on on-line forums trying to jostle ideas until something new began to emerge. Time will tell. Dark matter still has to be explained by the mainstream science community. Prof Brian Cox was confident that in two years or so they'd know 'one way or the other' I think.

Please:
I am assuming the body of the essay does not include the abstract. If I include the abstract I exceed 25000 characters and 9 pages. So can I put the abstract under my essay title in the PDF?
I counted body + figure captions + title, with your counter and I am very close to 25000 characters. I remove my figures when using your counter, but my body (no abstract) with figures will be properly within 9 pages. The characters in the figures are not verbose (not abusive) but If I count those I go over the 25000.
Thank you.

Hello Eric --
There is some flexibility in the contest rules here. For instance -- Does the essay body include the essay's title, or the authors' names? Does a separate title page with just that info count towards the page limits? The rules are not completely clear, so we have developed a few guidelines. Please keep in mind that since these are guidelines, they may change, although we always intend to be fair to all entrants and to the spirit of the rules.
Well, in short, to answer your questions---We usually do not view the abstract as part of the main essay body, unless it appears to be other than a summary of the essay [i.e. if the author is sneaking in extra text]. We do usually insist that the entire essay file fit within 12 pages.
Let me just pose the question for consideration--why include the abstract in the file at all? We ask for an abstract for the webpage [and readers will see it there], but the essay itself should not be intended as a journal article. However, that is the author's choice.
For characters in figures---here, we have to consider entries on a case-by-case basis. Characters in captions definitely count. If the figure itself contains explanatory text, we may count it. Labels on graphs of data we may overlook. I recommend, however, that you consider all characters in the figures and adjust your essay length to include them.

FQXi Administrator Brendan Foster replied on Sep. 10, 2012 @ 18:03 GMT
Yes, sure thing, but I will answer in reverse order---
Community rating -- The "Community" members are the essay contest entrants plus FQXi Members. The Community ratings are therefore the ratings placed by community members. The current ratings numbers are not displayed, in order to create suspense, but you see the current order when you select the option to sort by community rating. The current finalists are the first 35 [plus a few more if there is a tie at the 35th spot].
The 'Top Essays' -- every Monday, we change the list. We post the 3 or 4 essays with the highest community rating, UNLESS they were featured the previous week. This last clause means that sometimes the featured essays are not the top 3 ranked; however, this way, we can feature more essays. For instance, George Ellis currently has the top ranked essay, but he was featured last week---therefore, we don't feature him this week. Instead, we have 4 essays that have not yet been featured.

Hi Brendan,
I was watching how the entry count went as the deadline approached. I also had noted that the community rating choice was working (I did not think it was suposed to work until all entries were in). On the day that Sabine H. was listed (Aug. 31, 2012 @ 12:07 GMT) she was at the top of the chronological listing. I then checked the community rating listing and she was also at the top of the list. I went back and forth a few times between chronological and community and noted that this was true of a lot of the entries (if not all) that were in Sabine's group. I also noticed this effect on other days.
The community listings eventually became more "normally" distributed after the deadline. My initial thought was that the algorithm for the community listing is very strange ... a combo of chrono and community.
In my humble opinion, this was just too goofy to be a "shenanigan".
Also, it strikes me that more and more entries (particularly the high power ones) are choosing to submit on the last day. I was thinking of a way to get some funds for a worthy FQXi project.... charge a sliding fee for entries.
For the first month the entry fee is $0.00 after that it is $1.00 per day. This would help with the overload at the end. Perhaps you can fund another prize "the most goofy entry" so I can get to the finals.
And congratulations, It looks like this contest is gaining momentum.

So let's be clear Pentcho--are you claiming that an essay was at the top of the list but you know for a fact that it did not have a rating that put it at the top of the list? Is the statement that, people who like an essay should be polite and not vote for it until those who do not like the essay have voted? Or is the statement that, essays should not be placed into the list until they have had a chance to collect enough votes that normal statistics take over from the statistics of small numbers?
Thanks Don--in fact, we saw a smaller percentage of the total number of entries come during the last week, compared to previous contests. In past years, over half of the entries came in just the last week. This year, it was slightly under half. Earlier entries do get an intangible bonus though--they get more attention, owing to the longer time they are up and the smaller pack of fellow entries at the time they appear.

I'm not sure I understand the question. Do you mean--why did some essays appear after the contest deadline? The answer is, it takes a few days to process the entries, so that some entries are not officially approved until after the deadline. As it says in the contest rules, it can take up to 7 days for this process. At this stage, all essays are now online, so happy reading.

Dear Brendan,
This year's edition of the contest was an even bigger success, and I wish to congratulate the organizers.
There are so many essays, but unfortunately there is so little time to read them. I submitted the essay in a peaceful period, but it is unfair to the latest entries, which are so crowded, and definitely there's not enough time for them to get the deserved attention, and for their authors to give their attention to other essays.
That's why I would make a suggestion: why not giving us more time to read and discuss the essays? It is obvious that there is not enough time, even for the earlier entries. After all, we don't expect the next edition to happen right now, so extending the time with several months won't hurt. If you can extend the time until the next essay contest, we will have more time to read, with less pressure, and the assessment would be more correct. Maybe it would be not fair to change the rules at this time, but you can send to each contestant an email and give us a possibility to vote for this proposal.
Best regards,
Cristi Stoica

Dear Brendan Foster,
I noticed a week or so ago that my number of comments went from 203 to 201 and this morning I note that the number went from 224 to 222.
I have not asked that any comments be removed, and, because I and my guests have written many interesting comments, I do not want them removed. Can you tell me what's going on here? There were, to my knowledge no insults or incorrect statements of fact that would justify even the consideration of such removal, and I do not think it should be possible for others to remove arguments that they do not like. Is there any way to track such removals, and have them restored. I know that you are already under a tremendous workload, but I believe this is a significant problem. Believing these comments are 'permanent' I have not been backing them up, and many comments take quite a bit of thought and effort. For someone to erase these, for whatever reason, is not right.
Thanks for your consideration.

Brendan Foster: Much humble appreciation for the current exposure and its potential for a meaningful scientific hearing. I have sought 10 years for a fair hearing. It looks like I have the only essay containing description of original experiment to back its theory and conclusions. This is what separates physics from philosophy. However, my position is surely hard to take, and I expect arguments crying that my work was not peer reviewed, or something. Well, lets do a good job. I am willing to demonstrate the Unquantum effect anywhere. My portable gamma splitter now works and my portable alpha splitter is ready to test. I can bring them both to a FQXI San Francisco Bay area office or site of a contest sponsor.
An up-front recognition of this demonstration idea could make this contest a meaningful newsworthy win for everyone involved.

The latest
FQXi twitter physics article:[quote]Wang said the new field equations also lead to a modified Newtonian gravitational force formula, which shows that dark matter plays a more important role in a galactic scale at about 1,000 to 100,000 light years, but is less important in the larger scale, where dark energy will be significant (more than 10 million light years).[end quote]
Very interesting article and concept. I think they are on the right course. It fits with the idea of non-Newtonian matter being created at the centre of stars and spread to the planets via supernovae events and comet impacts imo. This fits with the scale limitations mentioned . Someone tell Mr Wang for me please!
Newton would have assumed that stars created non-Newtonian matter at their cores due to their spin rate and super high gravity field. Older stars would therefore have more of this extra force on the plane of rotation. This fits with the spiral galaxy rotation curves which have a central bulge of young stars and an outer disk of older stars which rotate faster than expected(!). Is the Main Seqeunce of Star Classification missing the onset of creation of non-Newtonian matter? I think it is. The evidence fits like a glove imo.

It's a good essay competition, thanks for setting it up. However there is a negative side. While I have had many good discussion with some participants, I have to say that I am disappointed by the aggressive, rude, and sometimes downright insulting note of some of the comments I have received on my thread. I have only flagged one as truly objectionable, but quite a few more have been pretty unpleasant. It is quiet a deterrent to taking part in these discussions.
Is this just an aspect of the general unpleasantness of the blogosphere, or is it more a reflection of the arrogance and condescending attitude of some theoretical physicists?
I think it would be improved a bit if you refused to accept anonymous posts or pseudonyms. Then those who are really rude are at least identified and cannot hide behind a shield of anonymity.

Dear Professor Ellis,
May I offer my two cents on the issues you have raised?
You ask:
"Is this just an aspect of the general unpleasantness of the blogosphere, or is it more a reflection of the arrogance and condescending attitude of some theoretical physicists?"
I would say both.
Blogosphere is a public forum, and as such it offers democratic freedom to all walks of life---from gentlemen to criminals. Sadly, what you have experienced is only a fraction of what I have experienced in the past year or two.
Moreover, theoretical physicists do not have a great reputation in this matter. As they say, a few bad apples can spoil the whole basket, and that is what you have been experiencing.
In an open Internet forum like this there are also other issues such as trolling etc., which psychologists are only just beginning to understand. These are aspects of bad human behaviour usually suppressed outside the cyberspace.
The issue of anonymity is a technical issue, and I will let the FQXi admin sort that one out.
Best wishes,
Joy Christian

Hello George -- Thank you for the input. I do apologize to you and all our essay entrants and forum users, for negative experiences like this. The participation of the authors and FQXi Members makes this contest unique, so we need to find ways to make the forum aspect enjoyable and worthwhile as the contest grows.
You have hit on a point that we need to think carefully about. We want to somehow balance the system's "democratic" openness as Joy says, with the need to have a sensible, meaningful, useful discussion. Your idea of non-anonymity is most likely a good step. Maybe only allowing comments from other entrants and Members? .
Ultimately, there will likely have to be a higher level of moderator oversight. For the time being, you [and all the other users] can feel free to flag posts as inappropriate. The messages go through a second stage of review before deletion, so this process actually helps us get a feel for what forum users consider acceptable.

Georgina Parry replied on Sep. 19, 2012 @ 01:26 GMT
Dear Brendan,
I think it would be a pity to limit comments to entrants and members only, as I would really value comments from the wider population too. Any one interested enough to take a look at what is going on in the FQXi contest, who is not a competitor, is probably an interesting person. I would really like to speak to those members of the public that have voted on my essay, if they are not just other competitors really. I feel I must be being misunderstood. I value the opportunity to speak to anyone about the reasoning behind its structure, the use of the framework for analysis of the problem that was set and the positive, forward thinking (rather than confrontational and pessimistic) nature of the whole essay.
I have really valued the openness and gentle moderation of FQXi over a number of years. It is unfortunate that it has been abused but I have also learned from hearing people speaking their minds. Non of us are compelled to speak. We can ignore unpleasant comments or personalities if we choose and we can flag comments that we think are offensive or inappropriate- that's enough, together with a watchful eye to see that all is well and an occasional comment. I do want the reassurance that there is someone there in the background who does care what goes on. There is a difference between a light touch and complete indifference.
I don't think it is necessary to make people give their true identities. It does limit freedom of speech. I am never anonymous because I don't have a professional reputation to uphold but other might who could not speak their minds for fear of the repercussions. While I think you are right to remind people to be respectful It would be a pity if all comments were nothing but platitudes and ubiquitous praise for everything written. I don't want a pat on the back and a "well done Dear" but honesty, even if I don't like it, which I can address by explaining what I have done and why.

FQXi Administrator Brendan Foster replied on Sep. 19, 2012 @ 18:57 GMT
Hi Georgina -- I agree now, limiting the commenters is probably not a good idea. It would also be impossible in practice for us to enforce a rule requiring real names.
Although I would say that, on the question of openness of discussion, anonymity does seem to give some people the impression of a license to be obnoxious or aggressive. And too much of those sorts of comments can also inhibit others from speaking freely. (but then, some people don't need anonymity to be rude.)
I don't know the best answer, but I think it is important for all of our site users to understand that these forums ARE moderated, and in fact have a relatively high level of it.

Brendon,
Would there be a way to better separate the flag and reply buttons? Occasionally I follow this on my phone and have it decide I'm touching the flag button, rather than the reply button. I've canceled them on the check page, but it would be nice if they were not so close together.
Also on the blog pages, there is a list of recent comments posted to the contest entry pages. Rather than just list previous contests in that space on entry pages, for those of us who are time challenged, it would be nice to have that feature on the left side of all contest entry pages as well.

No you may not. Whenever I find an argument of mine relevant, e.g. in a reply to Giovanni Amelino-Camelia, I must be free to use it, even if I have already used this argument countless times elsewhere. By secretly deleting it you bias the contest in favor of your friends.

I am upset for the insulting comments to Ellis.
It is difficult in internet to identify a person (alias in facebook, relay emails, etc), and it is difficult (and irritating loss of time) a secure access in a closed blog; until now I see a little number of offensive comment in fqxi weekly blogs (I am sure that the community members are innocent), and interesting comment in each field of the knowledge.
I think that the only possibility in an open blog is delete immediately the comment that are considered offensive by an entrant, or a blog author, or the administrator: if you give a delay time (some hours) between the author (or entrants, or administrator) reading and publication, then the spammer have not the possibility to be read by the community: sometime the people say worlds should not be remembered.

Hi John -- good suggestions. There's certainly plenty of room on the essay page sidebar, given the length of the list.
Domenico -- a delay is also an interesting idea. We don't currently review every post--but I wonder if an automatic delay alone would cut the thrill of appearing online, and slow the rate of hotheaded posting. Someone must have studied this already somewhere.

For an example of the huge arrogance of parts of the the theoretical physics community, look at the postings on my thread by a troll who uses the label "There is nothing new under the sun". He dismisses out of hand Roger Penrose and Sean Carroll, as well as Denis Noble - an FRS who is a world authority on the physiology of the heart.
Extraordinary how these guys can't see what a bad light they throw on the theoretical physics community. Presumably it's their professors who are leading them astray by giving them bad examples indeed he makes that explicit in his postings. They don't have any openness to ideas that come from outside the silo of their own speciality and they don't display good old fashioned courtesy.
Theoretical physics deserves better.

FQXi is the sole arbiter and enforcer of these guidelines.
This self-referential statement means that as acting forum administrator, I make the final call as to what is offensive or inflammatory. Unfortunately, there is no rhetoricological calculation to decide every case, so I make subjective decisions based on input I receive from various sources. These sources include complaints from forum users, both on the forum and in email; another source is my own experience in seminars, conference rooms, and other professional settings.

And next, just a clarification/reminder of how the voting works.
The main point is: The pool of finalists is chosen by the results of COMMUNITY ratings, and not the PUBLIC ratings.
The Public ratings are more or less "for fun". Anyone can place a public rating.
The Community ratings determine the finalists, and also affect the final winners. Only contest entrants and FQXi Members can place community ratings. The Community ratings are not currently shown, in part to add a hint of suspense. You can, however, view the current order of rankings by sorting the list of essays by community rating, in the list of sort options at the top of the page of essays.
If you are an entrant, and you have been placing Public votes---Stop! Place Community votes, not Public votes.
If anyone has questions, please let me know.

Constantinos Ragazas wrote on Sep. 19, 2012 @ 02:06 GMT
Brandon,
May I humbly suggest the list of finalists be selected as a percentage of the total number of essays? Rather than a fixed number of 35. Thus, this number will automatically adjust depending on the total number of essays. If we were to take, for example, the same percent of final essay in the last contest and apply this to the current contest, the number of finalists would be 54. The top 20% I think would be a fair number.
This is especially important in the current contest with 271 essay over many variety of topics by both physicists and non-physicists. Otherwise, the “professional entries” will dominate the final list and these will likely be limited to the same topics of interest. So in fairness and in scope, I think using percent is better.
I am thoroughly enjoying this contest. Great intellectual stimulation! Thanks!

Hi Constantinos -- thanks for the suggestion. At this stage in the contest, though, we can't make changes to the official, legally approved rules, which includes the numbers of finalists, the end dates, etc. It is something we will consider for the next time though. Especially if we expect the contest to grow even more, we may need to make various adjustments to the "infrastructure".

I understand! Will 'community rank ties' be treated the same as in the last contest? That is, all tied essays in the community ranking be treated equally the same?

FQXi Administrator Brendan Foster replied on Sep. 20, 2012 @ 14:46 GMT
Yes, essays with equal scores are in equal place.
err, I'm not sure if what I just wrote makes sense so what I mean is --- as it says in the rules, ratings are only calculated to the first decimal place. If two essays both have an average rating of 9.4, for example, then they occupy the same "place" in the ranking.
Now in fact, when we say "top 35" essays are the finalists, we still allow for a tie at 35th place, which means there may actually be MORE than 35 essays in the final pool. For instance, if the 35th essay has a score of 5.0, and there are 5 more essays that also have 5.0, then we include all those essays in the final pool.

Hi Brendon, I too would appreciate some clarification on that point. Last year there was a tie at 34th place and all of those essays went through to final judging making more than 35 essays. A question was asked and answer given clarifying that that was the case. I assumed therefore that as it was the top 35 essays going forward according to the rules and an extra number had already been included because of the tie, 35th place, my essay, did not go through to the final judging. Which was a disappointing outcome as I had high hopes of being a finalist because my essay had held a higher position prior to the end of the contest. Was that what happened last year and will happen again or is it all essays ranked up to and including 35 that will go through?

Hi all -- I see what you are asking now, and the answer is No, we don't do that. What we do is, first take the top 35 entries. We then look at the 35th entry, and if there are additional entries with the same rating as that one, we also take those additional entries. We only consider a tie at that spot, at the cut-off.

Hi Brendan,
This is my understanding -IE not the top 35 SCORES but the top 35 essays in NUMBER, as there may be ties before getting to 35th SCORE. Each of those are counted individually towards the total of 35 essays in NUMBER, plus any tied with NUMBER 35. Correct?

I'm sad to discover that the essay I posted, which I so far still believe to be a worthwhile, mathematically curious essay, has generated almost no discussion to speak of, and that apparently it is community-rated middling to low. Certainly I consider my material to be experimental, and it would not surprise me if there are errors either trivial or serious within it, but it seems very much not worthwhile to have posted it in this venue, where there has been one moment of praise but no criticism.
I guess I'm just kvetching that the current system seems to me not to work well for my essay, but perhaps one option might be that instead of a single community rating, the community in a future essay contest might be invited to make multiple assessments, "mathematically curious/interesting", "philosophically curious/interesting", "accessible", or whatever other aspects FQXi would like to see represented in an essay. Although I looked at all the abstracts and looked at and rated some papers as they appeared, and I've looked again at any of the top community rated essays that I hadn't previously noticed, at this point I can't bear to take the time to trawl through all the papers to find whatever I might have missed. I suppose that means that someone else, whose comments on my essay I might welcome, will likely also not find mine.
The change to not showing the number of and the levels of community ratings seems to me to be a dangerous loss to the feedback process that underlies improvement in science. How about generating graphs for each essay that show the distributions of the community and public ratings that it has received? More data and openness has very different consequences for a community than secrecy and ownership, albeit not always better and albeit more data and openness will always be embarrassing for some individuals.
Although this is at least implicitly critical, it comes with my best wishes,
Peter Morgan.

Hello Peter -- as the contest continues to grow, it could very well be useful (and fun) to introduce additional categories like you suggest. One downside that comes to mind is, Community raters generally don't have the time or inclination to sift through all the essays. Asking for multiple ratings categories will add a tiny bit of mental energy expense that might suppress the amount of voting even more. I wonder if it would be productive to have entrants decide themselves when entering, what category they would want to enter.

Thanks for your reply, Brendan. Another category that I would like to see would be "Novelty(1-10)". A brainstorming session would throw up something like "I can use this idea(1-10)", which to me is the highest praise there is.
After sifting through whatever might be generated, I'd see it as a line or list of four or five community categories, which anyone could fill in or not, as well as an overall community rating. No loss if no-one fills in any, but it provides telling metadata both to FQXi and to the community if some categories get more play than others or if a paper gets low novelty and high accessibility, or in whatever other combinations. Such categories allows the community to praise good aspects of a paper without marking it down where it is weak, by just not entering a rating for novelty, say. I suppose that ordering would be possible by any of the rating categories.
I'd hope that no-one would community rate an essay without reading it and thinking at least for a moment. Once one has a feel for the categories, rating in those one thinks relevant to an essay shouldn't take long. It's not cost-free to implement such things, of course, because it takes design and programming to implement anything new, but without new ideas of some kind the FQXi essay contests will presumably stagnate.
Sad that "Fun" is not something I'd say about research. It takes something like compulsion or obsession, and a putting aside of at least some worldliness, to keep at this stuff for decades with only a little positive response and a possibility or probability that no-one understands anything of what one writes or finds it interesting, useful, or worthwhile. That said, perhaps there should be "Fun(1-10)". Selection of essays to be considered by the judges could include some number that rate highly in each of the categories.
I guess my conception of this was not as I read yours to be, that essays would be entered into different categories. I think a significant part of the essay contest should be that the community decides what an author has written, which may be different from the way an author wants to be taken. Hopefully an author can accept that they have written something that was taken by the community in a way that they did not intend.
Anyway, I expect FQXi have plenty of ideas for improving the contest without me going on at excessive length. Hopefully some ideas will work well and the ones that don't will not be too destructive.

Georgina Parry replied on Sep. 24, 2012 @ 21:35 GMT
Peter has made a very good suggestion to consider for future contests. I would find it easier to vote for aspects of an essay such as relevance (or answering the question), accessibility, lack of errors, novelty, etc. rather than just giving one overall score. Currently the different merits and shortcomings of an essay need to be weighed up to give one final score. That, for me, is the difficult part. It hard to decide what an essay should be fairly awarded. For example should an essay that falls severely outside of the guidelines be marked high or low if it is very well written and fulfils other aspects of the guidance that was given?
It might also discourage the awarding of a score on the basis of a hasty first impression from a quick glance, or reading of the abstract or biography of the author, or tactical voting. Cumulative scores for the different aspects could be collected and then there could be awards for each aspect as well as for those essays scoring top overall in all of the categories. How an essay has performed in the different categories would be useful for authors, who could use that information to evaluate how their work has been received and could then use it as guidance for future writing.

Hi Brendan,
I'm sorry to say that I have apparently fixated a little on the structure of this contest, so that I was struck when the recommender system run by Elsevier, ScienceDirect, recommended to me this morning an article in Physics Reports,
"Recommender Systems", which I found an interesting read, and, I think, pertinent to the FQXi essay contests.
What FQXi is running here seems loosely to follow the pattern of a recommender system (there is a whole essay written by each member of the community that could be used as a starting point for generating recommendations, and the winner could be said to be a most recommended essay), so perhaps you might think about consulting a recommender system expert.
At the most elementary level, as a starting point that would be refined by actual recommendations, insofar as I use all of the words quantum, field, and renormalization in my essay, for example, I would perhaps be more interested to look at any other essay that also uses those three words, or at any essay that shares some number of words (or, following Google Ngram, multi-word sequences; but, not, perhaps, has, is, and of). Google Ngram is not ultimately the most illuminating approach to intellectual history, but it is one way of finding a starting point.

Hi all -- thanks again for the comments. I do like the sound of a novelty rating--I have to admit there are a few essays that I have read and thought, not a first prize essay but what a neat idea. I'll check out the recommender link.
And actually, if you look at the contest rules, at the top, it mentions that the expert panel will be instructed to give a 2/3 weight to Interest, and a 1/3 weight to Relevance when making their ratings. Although of course there are subtleties like, if an essay is totally off the contest topic (i.e. not at all relevant), than how interesting is it in the context of the contest?

"I'd hope that no-one would community rate an essay without reading it and thinking at least for a moment."
I'm pretty sure that most essays will end up being rated without being properly read (or not being rated at all for that reason, which amounts to getting a negative rating). Even if the essay is read, people will tend to judge it based on whether or not they agree with the views of the author (if it fits in with their way of thinking), and not based on the official criteria.
If you don't get far in this contest, you can always submit the essay to a journal or just out it on arXiv. I did that with my essay for the 2008 Nature of Time contest,
see here. It got the attention of a New Scientist editor and it appeared in that magazine.

This is a super important event, and one for all time.

With your second question here, the Community ratings are not visible at this time. The person leaving the rating would not see a change in the community rating, because they cannot see the community rating at all. If the Public rating changed, it is presumably because a public rating was also placed during the same period.

I don't know about rating manipulation, but the sociological factors definitely have far greater impact on the rating of an essay compared to its actual quality.
For example, if you are willing to sell your essay by pretending to be interested in other people's essays and make some seemingly intelligent but perfunctory comments on many essays while not forgetting to be nice, then the rating of your own essay will almost certainly go up by a huge margin. Try it and see it for yourself. It is all about who has more energy to do the door-to-door soliciting.
More disturbingly, if you have more friends among the FQXi members and among the participants, then the rating of your essay will be much higher much quickly, and it would stay higher regardless of the quality and contents of your essay. All you then have to do is make some right kind of intelligent sounding noises every once in a while. On the other hand, if you are a genius nobody with a bright idea, then this contest is not for you.
This is almost certainly an interesting sociological exercise than a physics contest. It is an exercise for and about a certain community, not for and about physics.

Instead of community rating there should have been a community refereeing system, as is costumary at conferences. Participants who have some academic experience (say published more than 3 papers in peer reviewed journals) could be assigned 4 essays which they have to evaluate based on the criteria. Then every essays gets a few reports. The experts then look at all the referee reports and assign a preliminary rating to the essays based on these reports only. The essays then get sorted based on this preliminary rating, the top 35 essays are then evaluated again, but now based on a reading of the essays themselves.
The other essays also get assigned a final rating, but this is then based on the referee reports and the contents of the essay. If one or more of the referee report suggests that the essay is very interesting, then the expert may want to read the essay in detail, otherwise the expert will take a quick look only. Essays that didn't score high due to one or two bad referee reports will then get read and evaluated just like the top essays, while the essays that only have negative referee reports only get looked at quickly.
This way, all the essays will have been read and evaluated rigorously based on the criteria without that being too much of a burden on the community.

Dear Pentcho, All,
I think all we can do is try to be impartial and hope that others are too. I really hope that my essay will be ranked according to its merit but, like others I am sure, I am concerned that it will not be fully appreciated at a quick glance and not at all if it is not read. I now wish I had chosen an eye catching title!
I am not sure whether it is grasped that; the method of systematic thinking that is presented is also being used to address the essay question and beyond. It is offering a solution not highlighting problems and talking about problem solving only. I have not made the essay about the explanatory framework because we were advised not to use the contest as an excuse to just discuss our "pet theories" but to present something new.
I regret that I can not read all of the essays but I have and continue to try to look at a wide variety of essays, choosing to spend more time on those that I am able to comprehend (without too great effort on my part) or find interesting for other reasons. That includes those of people I have previously spoken to on line and people I have never before encountered, Members and non members, physicists and non physicists, high, middle and low in the current rankings. I have begun to vote for the essays even though it is hard to give them one overall mark as they all have their good and not so good characteristics.
Whether I am being fair or not worries me though I am probably over thinking what is required. I think all we are doing as a community is saying to the judges this is probably worth looking at or this is probably not. If an essay does not have enough votes for the community to have made that judgement of it, it would be good if it were given an evaluation by some members to see if it ought really to be a keeper, or not. That might happen after community voting ends.

"On the other hand, if you are a genius nobody with a bright idea, then this contest is not for you.
This is almost certainly an interesting sociological exercise than a physics contest. It is an exercise for and about a certain community, not for and about physics." (anonymous, 3 posts above this)
The problem, basically, is that a peer review system does not work, it just propagates existing ideas.
I do not know the solution, but it is truth that we are seeking, not maintaining current dogmatic beliefs.
Really, all essays need to be read by a panel of judges from a diversity of fields, and rated with reasons for their rating. But this is not practical in our busy world!
This is a very big problem for the advancement of human knowledge ...

This is not cool at all. I was in the first 10 positions at the community rating, and in few minutes I found myself 50 positions below. Being the final days of the competition, and judging by the previous positions, I think that I got many ratings already. How many simultaneous ratings of 1 could I receive in several minutes, to outweigh so much the votes I already had?

Hi George,
it's probably just because more people are starting to vote as the time in which votes can be placed is coming to an end soon. It was a bit of a roller coaster ride at the end of last years contest too.
I regret that I haven't been able to read all of the essays but it isn't something I have felt capable of attempting.I think the whole point of having community voting is because it isn't reasonable to expect any one or just a small number of people to thoroughly consider all of the essays. The voting part of the contest is important. There are a very large number of entrants and if they -all vote- on at least some of the essays that they have read then there will be more fairness, as each essay is likely to have been voted on by more people.
Your essay has been very buoyant throughout the contest and you have done a remarkable job of responding diligently to comments on your thread as well as commenting on others. I would be extremely surprised if you were not a finalist after such sustained popularity of your essay. So hold tight and enjoy the ride.

Dear Joy,
Positions change when people vote. When there are few votes positions can change a lot, as the new vote has a large influence on the average score. When there are more votes the change in position becomes less as the latest vote is just a small part of the new average score. The big fluctuations probably reflect that there has not been much voting going on until recently. That's all I think is going on.
Balance comes from lots of people voting and the position is then more indicative of the communities overall opinion.

Georgina Parry replied on Oct. 5, 2012 @ 09:36 GMT
Some differences of opinion on the essays is to be expected. Which might lead to wide fluctuations when numbers of votes are low. There is a problem though if people are not using their votes to give an essay a ranking that reflects their opinion of it, based on the various judging criteria but attempt to alter the current level of essays by over or undervaluing them.
It is fairer to give them a reasoned points value irrespective of current position and let overall community voting balance out where the essays end up. There was some concern within the community about the voting last year but Brendan did say, in a post about this contest, that the community had done a good job of selecting the essays last year.

Christi is right, there's definitely serious dishonest trolling going on with collusion and mass 1's being dished out. Mine dropped over 100 places from 3rd to 107th overnight! There is no way that can possibly be from honest voting. You must have the means to find out who it is doing this.
Certainly no essay in the top 40 will honestly deserve a 1 or 2 score from anyone. Perhaps any such obvious dishonest tactical votes should be discounted to ensure non-manipulated results and to save the good name of the contest.

I can't comment on the deleted comments as I hadn't read them, but it can't be denied there's a case for that provision, as there is for removing the effects of trolling. You have 'pushed the limit' frequently, though I personally saw nothing I'd think censurable.

Many of you have noticed some surprisingly large changes in the Community rankings in the past few days. In fact, we have discovered an oddity in the voting records. It appears that some entrants are able to vote multiple times for single essays, despite our system safeguards to only allow one vote per essay, per entrant. The multiple votes cause big changes in the rankings, and another big jolt occurs when we clear out the bad votes. We are currently looking into the cause of the multiple votes.
Fortunately, we have complete records of every rating, including who has placed them, so we can quickly locate and remove doubles, if any more occur. Later this morning we will have to do another cleaning, and we will check again when the voting closes this evening. If there is any other sort of technical issue, accidental or malicious, that leads to invalid voting, we always have this ability to check the records.
I apologize on behalf of FQXi and our tech crew for the mishap. I want to assure everyone that the non-multiple ratings remain intact, and the overall rankings will be based on the correct votes. If any of you believe you may have managed to vote twice for an essay inadvertently, please let me know at foster@fqxi.org. Your details can help us better understand the source of the problem.

My hope of the goodwill, "sportsmanship" and honesty of the community has been damaged.I think the perpetrator/s should be disqualified from winning this contest, excluded from any further contests as cheats, or at the least be denied any voting privilege.
There may have been a technical error which allowed unlimited voting but it was the competitor/s who chose to abuse the opportunity rather than just flag it up as a problem to the FQXi staff. Not only is it dishonest but has caused distress to honest competitors helplessly watching their essay's position rise and fall wildly.I too saw my essay fall 100 places and felt hurt by thinking it -so- greatly undervalued or disliked by the community.

Dear all,
Something I've noticed, in addition to the recent volatility, is that the mean community score seems to be distressingly low. Every time I rate an essay below the top 100 it seems to jump 20-30 places, and I have not given many 10's, though I've given a lot of 6's and 7's. I am glad to hear that the recent ratings chaos is due to a glitch rather than deliberate manipulation, but I do wish more people would follow the contest guidelines that request a "supportive atmosphere of scientific conversation rather than a judgmental atmosphere of critical scoring and evaluation."
Most people have put a lot of sincere effort into their work, and it threatens the whole nature of the contest if a large percentage of the contributors are playing "gotcha," either with comments or with ratings. Participation isn't a right, and we'd all be nowhere if FQXi and the sponsors took their ball and went home. It's amazing how some folks behave when afforded anonymity. Anyway, I'm probably preaching to the choir here, because most of the recent comments are by people who have made a major constructive and encouraging contribution on many threads. Take care,

I managed to obtain a copy of an email sent from a member of the FQXi Technical Support (his identity will be disclosed if needed) that confirms that some authors were allowed unlimited voting of essays. This must explain why some people dropped 50-100 positions in about 15 minutes, when all were in the top ranking during one or more weeks.
The email has date of the day 3 and says "This problem was temporary, and has been corrected." Well, it seems that the problem was not corrected.
At the same time, I have seen a pair of essays suddenly ascending lots of positions up to the first positions (about more than 200 positions for the 1-page essay mentioned by Peter) in the same time span.
Moreover, I have also noticed that my public rating and that of people around me has dropped by someone giving us a "1".

I hope mine should be corrected also - independent of the result (up or down).
It is a serious problem in my opinion when the ranking chances aren't equal. So much work, hopes and words have been invested from everybody to make this contest a good and fruitfull contest.
I hope the technicians can fix the problem in the program's source code of those people who are "allowed" to vote one essay multiple times and then the multiple votings are erased and the correct result is executed.

Dear all,
By the way, on an amusing note, I have watched my pathetic "public rating" of 4.9 accumulate and hence know that it consists of something like four 10's, a 9, 7, 6, 3, 2, and six 1's (this may not be exact, but it is close). Most of the 1's have been accompanied by a drop in community rating, so this implies certain participants have been childishly bombing others with low community ratings, logging out, and then giving a public rating of "1" as well. If you look at the public ratings overall, most of them are awful except for those with a very large number of ratings, likely from friends. I suppose this is just human nature, but it augurs badly for our ability to ever escape this planet without blowing ourselves up. Take care,

I suggest that after the community ratings are established tonight, in the interests of eliminating any possibility of contest score-fixing, the community scoring made by each reviewer should be made public. AFAIK, no where in the rules does it state that the scoring is or should be anonymous, so this may be a way to root out any problems.

Hi all
we have Brendon's word that they can see multiple voting and sort it out, so the final ratings are correct. Thanks for fixing it, Brendon; presumably the technical glitch will be fixed next time.
There remain two serious problems.
The first is the people who took part in the vote manipulation and multiple voting. Brendon knows who they are. They should simply be excluded from any further participation in any FQXI event. This kind of behaviour should have consequences. These people are not imbued with the spirit Georgina hopes for.
Second is the problem of unacceptable postings. I have been subjected to some serious hate mail and some very unpleasant posts. What is needed is a facility that automatically excludes an individual from making any further postings on a particular thread once they have had three postings on that thread deleted by the owner, with the deletions being verified by the administrator (the latter of course being needed so that one can't delete stuff just because it is critical).
Critical comments regarding technical issues are fine; simple trashing is not. Hate posting should exclude one from the entire competition.
Apart from that it's been a great competition, with some good essays and some great discussions. Thanks for organising it!

This reminds me of the first FQXi contest, when my essay was on #1-2 at equality with Rovelli's, leading with 7 points, when the next had 4, at the time when the votes were scheduled to close (Dec. 15). I was the only non-member in the top 10, but the end was delayed to gather more votes, and I ended up without any award. I attach a picture taken the next day after the vote was supposed to close.

The nature of both reality and the judging is difficult to pin down. As George observes, the nature of the whole can be hard to deduce from the observable parts.

Cristi,
I don't think that there's any conspiracy to elevate club members or to restrict outsiders. It's that the structure of the contest, for better or worse, permits an overwhelming number of unqualified people to make irrational judgments.
For instance, in the last hours, some participant told me that he rated my essay a '10' on the basis of having read the abstract and a one-sentence conclusion -- with an implied message that I do the same for him. I expect that many more than that rated me on the low side for similar irrational reasons.
That's not the fault of the contest organizers. It's endemic to any contest that has open voting by people of diverse levels, and extremes, of knowledge. The process evens out for well known scientists, because the added factor of being known usually works in their favor; i.e., unknowledgeable raters will tend to err on the side of popular opinion -- though this can be a 2-edged sword for well known but unpopular scientists.
You'll notice that in the group immediately following the cutoff point (which includes you and me), there are usually a high number of ratings -- in the 30's -- while there are a significant number of essays above the cut with a low number of ratings, and some barely above the minimum 10 (in fact, one is an illegal 8, which I expect will be corrected) -- but with sufficient scores. This strongly indicates either irrational voting, or tactical voting by some with no chance in the contest, attempting to "vote down" the competitors they do not favor rather than "voting up" by rational judgment -- and probably a combination of the two.
Science is a rationalist enterprise, while open essay contests don't necessarily work that way. I see no resolution until or unless FQXi tightens its entry requirements, to blunt the effect of irrational judgments. I see no cure for petty jealousy, however, in any conceivable system.

Tom, what I said was about the huge changes that took place AFTER the voting closed and the results were displayed. For me, were erased three votes averaging at 9, which moved me from 23 to 44. I am not the only one, and I presume this is not the most dramatic change. Just compare the results at 00:01 with those at this time. You are talking about a different issue :)

Cristi,
It's the same issue. Just because the voting closes doesn't mean the count is correct until audited. I expect the system audit (duplicate votes) produced the errors, as Brendan said. Those errors can downgrade as well as elevate.

Hello everyone -- Unfortunately, we have had another technical issue that meant people were still able to place votes after the official deadline. Many of you have noticed motion in the rankings after midnight, and this was the cause.
We have now successfully shut down the voting. We will need now to remove all the votes placed after the deadline. So, I am very sorry, but the results displayed on screen are not the final results. I expect we will have the correct, final results displayed later today.
I apologize again for the confusion. For the time being, I am going to once again hide the community ratings, until we have them corrected. I want to emphasize again that we have the full records of the correct, valid ratings placed up until the deadline. All we need to do at this point is have the post-deadline ratings removed.

Brendan, you posted a wrong "final ratings". In my previous comment, I attached an mht file containing the community rating page, as it was at 0:01. To see it, download it on the computer and open with IE or other browser. In this page it is a totally different order, for example I am at #23, as I was also before midnight. On the new one, three votes of about 9 points were removed from my votes, and I dropped on #38. I attach again a screenshot took at 0:01. How is it possible that at 0:01 there was an order, and now you come with a totally different one, and say that this is what it was at midnight?

I think my complain deserves a resolution. I gave you plenty of evidence already, although it was your job to ensure the contest. 5 essays were removed artificially from the list of finalists, and no explanation compatible with the evidence is given so far.

We can think of this as physics, where pressure/scalar is converted to flow/vector.
Both content and mechanism play a part and while we many be focused on content, the influences of the mechanism cannot be overlooked.
The larger and long term issue is whether the premise of this contest and FQXi, questioning foundational assumptions, as opposed to extending the current paradigm ever further into the realm of untestability, gains traction in the physics community.

Despite our technical issues, I can now report that the official results are set. If you will count down 35 spots, you will find that we have a tie at the cut-off (4.3) so that we will have 36 finalists. This year was bigger by far than any previous year, so we will give a lot of thought on how to evolve as the contest grows. Congratulations to the finalists, and thank you to everyone who has taken part in the contest.

The comment by anonymous at Sep. 30, 2012 @ 06:29 GMT is right on the money. I believe the sociological factors, presumably allowed to creep into and contaminate this contest in order to keep the participants engaged, to a real extent hurt the essay contest's original purpose, to identify those novel ideas that can have a real impact on the field.
FQXi should get rid of this voting system altogether. Some time ago, I read that somebody called it a "popularity contest", and at the time I wanted to disagree, but now I find that this is an accurate description.

Concerning deletion of votes. The following complaint is on this page (Sep. 10, 2012 @ 18:36 GMT). It explains everything:
"Dear Brendan Foster, I noticed a week or so ago that my number of comments went from 203 to 201 and this morning I note that the number went from 224 to 222. I have not asked that any comments be removed, and, because I and my guests have written many interesting comments, I do not want them removed. Can you tell me what's going on here? There were, to my knowledge no insults or incorrect statements of fact that would justify even the consideration of such removal, and I do not think it should be possible for others to remove arguments that they do not like. Is there any way to track such removals, and have them restored. I know that you are already under a tremendous workload, but I believe this is a significant problem. Believing these comments are 'permanent' I have not been backing them up, and many comments take quite a bit of thought and effort. For someone to erase these, for whatever reason, is not right. Thanks for your consideration. Edwin Eugene Klingman"

Hi Brendan,
When things go wrong, I always look for incompetence before enemy action. I believe your web team is seriously incompetent. The first hint was when new entries went straight to the top of the community voting. This was a hint of things to come.
My thought is that the contest logic is faulty and was taken advantage of by some contestants intentionally and not intentionally.
If these problems are not incompetence and are actually enemy action, the problem is most likely a member of the web team who has an ax to grind with FQXi. This is more likely than an outside hack.
In my humble opinion.
And I believe you can handle it.
It is still a great contest (and a wonderful bazaar).

I think this is a very good suggestion, so long as non of them are involved in any way with the vote tampering. It will have been heartbreaking especially for those who had thought they were finalists but then had their essay drop out of the list after the deadline. Though it may not have been the fault of the organisers I think they could offer to make matters better by including those few essays. In recognition of the particular stress put upon those competitors and the sense of injustice or personal hurt they must feel.

I believe Tom is wrong. If an essay is accepted, then the author is "qualified" and can vote, period. With 300 authors, obviously there will be voting that does not meet everyone's approval. That's inevitable. By deciding to open the gates wide, FQXi intentionally let's a broad spectrum of authors participate. Some have very good ideas. While this affects the scoring, we still end up with the 'best' ideas floating to the top. The arbitrary cutoff of 35 means that some good ideas don't make it, but on the whole I think it works. [Although I still have some uncertainty about how things moved as they did after midnite.]
Another comment of interest: Anonymous on Sep 30, 2012 @ 06:29 wrote: "I don't know about rating manipulation, but the sociological factors definitely have far greater impact on the rating of an essay compared to its actual quality. -- For example, if you are willing to sell your essay by pretending to be interested in other people's essays and make some seemingly intelligent but perfunctory comments on many essays while not forgetting to be nice, then the rating of your own essay will almost certainly go up by a huge margin. Try it and see it for yourself. It is all about who has more energy to do the door-to-door soliciting."
Yes, there are definitely sociological factors at work. In at least two cases, when I argued with other authors in a comment, my community rating fell almost immediately by a large amount. I do not know, but I assume there is a correlation here. This, as far as I am concerned, is an excellent reason to keep votes secret. Otherwise human nature will yield retaliation, and everyone will defensively give everyone 10's.
As for the "pretending to be interested in other people's essays and make some seemingly intelligent but perfunctory comments on many essays" that is a cynical remark that was made last year by a number of losers, some of whom have appeared over the years to have little interest in any but their own ideas, and seem incapable of understanding that some others have a real interest in ideas. I personally look for points of agreement and disagreement between my essay and others and try to remark on both of these points. If that increases the likelihood that the author will be interested in my essay, so be it. Otherwise it may simply depend on the marketing of a catchy title to attract their interest.
Anonymous is right that "It is all about who has more energy to do [such]". It does take energy to study others' essays and make relevant comments. In fact I spent so much time working on my comments to Ken Wharton and Sara Walker and a few other essays that I never got to post them before the contest ended. The fact some don't have the energy, some don't have the time, and some don't have the interest, is simply a fact of life. There were almost 3000 highly dense pages of material in this contest and it is unreasonable to expect anonymous judges to read all of this. The current scheme of letting the community self-qualify the finalists is probably as good as it gets. In fact, looking at the top twenty essays in the community ranking, it's hard to argue that the result is totally flawed!
Finally, as there are no hard and fast guidelines for voting, I tend to score highly the important ideas and to give low scores to ideas that I think are simply wrong, regardless of the literary quality of the writing. I do not want popular but [in my opinion] wrong ideas to make it to the top. In many cases I can't decide and often don't vote for or against these essays. This is not a "writing" contest from my perspective. It is about physics ideas and should be judged as such.

You wrote: "we still end up with the 'best' ideas floating to the top."
Mass one-rating, as is the case in this contest, makes this absolutely impossible. An essay at the bottom of the rating list, e.g. Ronald L Bennett's one, could be much more valuable than Benjamin Dribus' top triviality. In addition, there has been mass deletion of unwanted comments and votes.

Edwin,
I think that anonymous person you quote has given an accurate description of this essay contest. Perhaps you really are that naive that you couldn't imagine that his comment has any relation to what is really going on, or it may be that you haven't actually tried to look at the evidence.
Just go to the fora of the low rated essays, and look at the comments given by some of top rated essay authors, especially when they are really close to the deadline. The description I heard someone give some time ago of that this essay is a "popularity contest" seems exquisitely accurate.
But, don't let me tell you what to believe, do make an effort and look at the evidence for yourself.
And for the record, I'm not in the top 36, but even if I were my opinion would be unchanged. In fact, before this essay contest even got started I had sent Max Tegmark an email on an unrelated matter but also included the suggestion not to make voting a feature of these contests. I think it is a horrible idea that seriously compromises its intended purpose.

Dear Pentcho and Armin,

I am not happy with the results of voting for 300 million Americans, either, but we have a 'one man, one vote' system, flawed as it is. Last night a number of students on a University campus were asked "Was it fair that Obama couldn't use his Teleprompter in the debate?" and about twenty said no, it wasn't fair!!!
Those ignorant voters affect the laws under which I live. The FQXi votes simply affect which papers the judges will look at. For example the judges will look at my paper, since I went from #21 at close of voting to #37 and ended up #32. But since I challenge Bell's theorem and 'collapse of the wave function', it is [I think] almost a foregone conclusion that I will not be a final winner, since this is accepted dogma.
Nevertheless, I believe FQXi provides a unique and valuable forum and one that allows us to present our ideas and exchange comments and questions. There is a contingent that seems to resent the exchange although some who have complained about this certainly seemed to participate in it while they were winning.
If one wishes to simply submit a paper and then forget it, then I suggest that one submits to peer reviewed journals and avoid the commentary.
I was #2 last year and was still ignored by the judges and I don't expect to do any better this year as #32, but I will still participate in the next contest. The feedback I get is valuable to me and helps me evolve my ideas. If I had to wait for perfect voting rules or perfect people to vote, I wouldn't get out of bed in the morning.
Not all of the essays I graded highly got into the finals and some in the finals I graded very low. But the voting is over and I thank those who voted for me. I would not have complained if I did not make the cut, but I would have been very unhappy if I made it and then got bounced out by after the fact changes. I think there are some rightfully unhappy campers here.

Edwin,
Alright, I am going to go paragraph by paragraph through your response because I am honestly unable to connect it to the problem that was pointed out to which your statement purports to be a response.
Your response begins with an attempt to draw a connection to the US voting system, the relevance of which to the issue at hand escapes me completely. The US voting system has nothing to do with this essay contest, it does not obligate the organizers to institute a voting system, and furthermore it is about politics whereas this contest purports to be about science. If I were uncharitable, I might think that you are trying to divert attention.
The second paragraph states the obvious about the impact of the voting results , along with your opinion about how your essay will be evaluated. What you say may or may not be true, but it is in principle falsifiable, namely if you do receive an award, but again, I fail to see the relevance to the problem at hand.
The next couple paragraphs are about the value of FQXi to out-of mainstream researchers and we are in complete agreement.
Is it better that this essay contest exists than if it didn't? Absolutely!
Does FQXi provide a "unique and valuable forum and one that allows us to present our ideas and exchange comments and questions"? Without a doubt. For example, although I strongly disagree with the local realist position, I laud the support they have given to some of its supporters, such as publishing Joy Christian's book.
But is any of this relevant to the problem being pointed out? I don't see it.
Your last couple of paragraphs describe your personal experiences in past essay contests including only one comment that I see as remotely relevant, the one implying that the current system cannot be improved because "If I had to wait for perfect voting rules or perfect people to vote, I wouldn't get out of bed in the morning." That one comment seems to be based on the fallacy that you need a voting mechanism in order to have an essay contest that effectively carries out its intended purpose.
Let me state the problem very clearly, and if you do decide give a response, please make it relevant.
The problem is: allowing authors to vote on each others essays contaminates this contest so that it is no longer about physics but about popularity. The popularity is either due to already existing name recognition, or due to pre-existing friendship with other authors, or due to tit-for-tat score exchange, or via rearend-kissing.
I agree that several of the essays in the top 35 are very strong and probably deserve to be top-ranked, but if the 35 essays had been picked just at random, you would have also have a good chance of finding some very strong essays in that mix, so that doesn't justify having the current voting system.
There are other mechanisms that could be used to evaluate the essays, depending on how many judges are available, but the current system is a very poor solution.

Dear Armin,
I don't think my response was as irrelevant as you seem to but let me address this specifically: "There are other mechanisms that could be used to evaluate the essays, depending on how many judges are available, but the current system is a very poor solution."
If you have specific mechanisms in mind, please state them.
I do not like your "how many judges are available" idea. The judges will almost certainly be picked from academia, where people have to toe the line or face the consequences. Even though these judges would be anonymous to us, they would be known to the FQXi selectors and probably to each other so we would still have the sociological issues at work, only less transparent. It also somewhat smacks of 'arguing from authority'. I think we end up seeing the overwhelming influence of academia in every contest. I don't wish to see more. I believe W F Buckley said he'd rather be governed by the first 400 people in the Boston phone book than by the Harvard faculty, and so would I.
If you have a voting and judging method that is free of bias, free of self-interest, and free of human foible, while at the same time capable of actually performing an evaluative function that is fault-free when judging attempts to break free of dogmatic assumption, then feel free to propose it. I will be happy to consider it, as, I'm sure, will all others here. I have yet to hear such proposals. I DO NOT favor going to judges, no matter how many, who are part and parcel of the institutional system. I'd rather take my chances with my fellow authors, all of whom are imperfect. At least there is a *chance* that thinking outside the box will be rewarded.
You yourself admit that "I agree that several of the essays in the top 35 are very strong and probably deserve to be top-ranked", but you go on to point out that "if the 35 essays had been picked just at random, you would have also have a good chance of finding some very strong essays in that mix, so that doesn't justify having the current voting system." Yes, "some", but I think we have a better result that just some. I think we have 'many' strong essays picked, almost certainly more-so than a random selection. I think you overstate the case.
So what's your idea. I repeat that I would not have complained if I did not make the cut, but I would have been very unhappy if I made it and then got bounced out by after the fact changes, as some did, and as I temporarily did.

Edwin,
My "available judges" comment was simply a concession to the practical constraints that may accompany any such effort.
Ok, my suggestion is as follows:
1. At minimum, if an author voting absolutely is decided to be in place, do not allow people to see the community ranking. The fact that the rankings are evident immediately introduces an extraneous consideration in rating that has nothing to do with the merits of the essay. Also, if someone in the forum of an author discloses that they gave a high rating, this should be reportable and grounds for some kind of repercussion.
2. Much more desirable in my view would be not have an author voting system in place at all. If you are concerned about academics influenced by institutional bias, then the more suitable judges might be retired physicists who are still actively following research developments. You could also have researchers at teaching institutions who are not subject to the same pressures on research topics.
In any event, I have the impression that the bias of academics active in research looms large in your mind. To some extent that may be true true, nobody is free from bias, but I think that your judgment of physicist's integrity in evaluating the arguments may be overly negative. While there are undoubtedly some dogmatists out there, I believe there are also many physicists who are willing to change their views on a particular issue if they are given a really convincing argument (And I am saying this as someone who has more than his share of ideas that contradict mainstream trends). Conversely, I think many of the people who propose out of mainstream ideas display the hallmarks of dogmatism, so this is really a two-way street.
All in all, the fact that the authors have more at stake than a panel of non-participating judges is a significant factor in my view that overrides these concerns.
You state:"If you have a voting and judging method that is free of bias, free of self-interest, and free of human foible, while at the same time capable of actually performing an evaluative function that is fault-free when judging attempts to break free of dogmatic assumption, then feel free to propose it."
Please Edwin, you know better than to propose such a blatantly obvious false dichotomy. The desirable alternative to the current system is not a perfect system, just one that is more objective. And I honestly do not think it is difficult to find one, because the current system is poor.
On your comment about me overstating the comparability with random essay selection, yes I concede that there is probably a positive correlation better than random between the top rated essays and the truly best ones. But is it the best way to identify the best essays ?
As stated before, I do not believe so and this is an opinion I held even before the contest began.

Just a thought: on a traditional grading scale, anything below a 6.0 to 6.3 would be considered an F, "fail". Interesting to observe that not a single essay managed to go above that, and that only 5 out of 270 essays managed to score above 5.0.
So much for the credibility of the votes. FQXi might have as well picked 35 essays at random.

I think it is unfair to turn Brendan and other organizers into scapegoats, while from the start there were obvious alliances forming among a certain group of contestants, just like in a TV game of Survivor. Some were so bold as to post their intent openly, addressed in the same form on a number of threads. Others fished around throwing more or less clear hints. And Mr. Danoyan openly confesses above, "I know that 10 people have rated me 10."
Why, Mr. Danoyan, how do you know that? Was the same expected from you in return? Did you oblige?
I find it astonishing that the same persons now act the offended party. And then of course there was a group of noisy, flamboyant schmoozers.. This contest was more of a social game than sharing of ideas. But this is only the reflection on "who won" and "how". Still, many essays at the top are very good. But agree that many are just iterations of old platitudes, some written in more entertaining style than others, and some are real sleepers without a word of original content.
It was a very interesting experience for me. I am not disappointed at all and hope the forum stays open for a while, so that I could continue discussion and get feedback.
Thank you Brendan! It must have been hard having to deal with all these manipulations and then be blamed by the very people behind it.

Dear M.V,
You made an astute observation about Yuri Danoyan, one of the ways in which he tried to manipulate the voting was to spam me (and presumably other authors) more than once with personal emails with links to his essay.
I assume that it was not Brendan's decision to have voting system in place, and if that is correct, I agree with your comments that the current eruption of frustration is unfair to him.
But somebody came up with this voting system, and it would be great if this matter was up for serious reconsideration.
I am glad that you enjoyed the experience and hope that you will decide to enter the next round, hopefully without the voting feature.

The system was designed by civilized people for civilized people. It is not the system's fault that some participants were paranoid types seeing conspiracies against them everywhere and so they felt that they had to band as a group and support each other with high ratings while bombing what they considered the establishment. I saw such a plan posted openly on several threads. The question is, how the author so approached should react? Inform organizers? Ignore the solicitors? Act evasively? Hint a promise and hope they will go away?
This is a difficult problem.
There were clearly alliances of two types, one primitive, the other one complex. Both were plainly visible. Perhaps there is a solution for the first type, but I doubt anything can be done about the other.

Dear M.V.,
Yes, of course we are civilized, but that doesn't mean that competitive urges etc. will not compel taking advantage of the system whenever it is possible.
When you say "I doubt anything can be done about the other", clearly discarding the author voting system would be one thing that can be done about it.
I mentioned elsewhere the problems author voting brings about, such as inhibiting honest discussion and feedback, encouraging people to manipulate votes, excess spamming of fora etc. so in light of these problems I wonder why you think that it is a good idea to be able to vote as an author on other essays? If you want to provide feedback on an essay, why is it not adequate just to write a comment? What is a value to being able to assign a number to the essay of a co-author with the knowledge that they can do the same to yours?

M. V. Vasilyeva replied on Oct. 7, 2012 @ 02:37 GMT
Armin, yes you are right. But then how is it a contest? Who and how is to judge? It is unreasonable to make some judges to read 270 essays. I barely read maybe 40+ and rated ~35. It's too much of a task.
In the past contests, only community members had the vote and the rest could only vote publicly. This deals with the first, simple problem, but does not solve the second.
Maybe, if the voting was hidden until the very end, that would at least take off some pressure. But the schmoozing will still remain. That's part of being human. Some do it very well, others not. But you can't avoid that.
How do you propose the top essays should be selected? By whom?

Karl Coryat wrote on Oct. 6, 2012 @ 23:22 GMT
Nobody has mentioned this, but I see a problem with the 1-10 rating scale. It allows entrants who give, say, 1's and 10's to outweigh those who would honestly rate the same essays a 4 and a 6. In other words, ratings-exaggerators automatically self-select to have a greater effect on the competition than honest raters. This is a serious flaw. A 1-3 rating scale instead, or perhaps a thumbs-up/thumbs-down model, would at least level the playing field in that respect.
I also don't see what prevents a person from submitting one or more nonsense essays under false names, thereby getting to rate their own real essay dishonestly and in a way that isn't traceable. I would bet that this happened at least once in this contest and probably previous ones as well.
So, I'd like to see a higher standard for entry qualification. A 6- or 12-hour delay in the community ratings might be helpful as well. If FQXi really wanted to tighten up the contest, it could weigh the ratings entered by members and previous essay finalists three times that of ordinary entrants, and weigh those of the judges three times greater still. If members and previous finalists have a greater influence on the rankings, I believe the final rankings would be much more true.
This is a great competition, but we need to tighten up the ship!

Dear All: please read and respond.
Every one of us---including Brendan and the others at FQXi, I'm sure!---has seen that there is a deep flaw in the voting scheme. It was obvious to everyone during the past few days that a number of people were scoring 1s to bring down others' average community rating. I'm sure none of us had imagined the full extent to which this was happening, so that only a handful out of the many excellent essays in this contest made it above 5.0 in average community rating. I'd like to propose a change to the voting scheme that I think would largely mitigate this serious issue:---
In future contests, community ratings could rather accumulate as running totals, and those with the highest scores in the end should move on to the list of finalists. At that point, averages could be calculated and the rating of finalist essays by disinterested expert judges could proceed as it will for this contest.
This system would promote community involvement, as well as entering one's essay into the contest as early as possible (although, look at the number of votes Ben Dribus got, who entered his essay on Aug 20 but then got really involved!). But it would also mean that if someone didn't like you, or thought their essay was better than yours (and I think just about everyone here thought their own essay was really the best one, as Hoang Cao Hai pointed out to all of us a couple of weeks ago), and therefore wanted to see your essay fall below theirs in the community ratings, the worst they could do to you is *not cast any vote for your essay*. In contrast, months ago I had someone come on my site making very rude remarks and eventually say that he had made it his mission to subvert any other essay that had anything to do with cosmology, since that was the topic of his essay and he felt that he had all the answers (ergo, in his mind, everyone else's essay that dealt with cosmology was junk). I'd rather he didn't score my essay at all, but I'm sure I got a 1 then, and I'm sure many essays got 1s throughout the contest for similar reasons. (By the way, I've been thinking for a while that it would have been better to wait until the end to enter my essay, so that this would be less likely to occur, because no subverter could stay on top of all 270 entries).
In this system, I'd be more apt to finish reading all the way through an essay I wasn't finding particularly enlightening, and cast a vote giving my honest opinion of it, since that would actually be a nice thing to do for someone, as any score would add to their running total. In contrast, during this contest I often decided to quit reading and abstain from casting a low vote, because I felt like casting low votes in this contest was a very mean thing to do, and I value my time too much to waste it simply being mean!
I'd really like as many people to respond to this post as possible, whether you like the idea or not, and in the latter case it would be great if you'd please state reasons. If we can generate enough discussion and come to some agreement about what would be best structure for these contests, I'm sure the FQXi would be happy to implement a fairer rating strategy for future contests.
Thanks for your consideration. And FQXi: thank you so much for giving me the opportunity to enter my essay into this contest and share my ideas with so many people. For many of us, this means such a great deal.

Hi Daryl,
Armin made a specific proposal above [Oct 6, 2012 @ 23:50]:
"1. At minimum, if an author voting absolutely is decided to be in place, do not allow people to see the community ranking. The fact that the rankings are evident immediately introduces an extraneous consideration in rating that has nothing to do with the merits of the essay. Also, if someone in the forum of an author discloses that they gave a high rating, this should be reportable and grounds for some kind of repercussion."
I think that if the scores were not displayed it would go a long way toward alleviating some of the incentives at work and would tend to shift the focus to the quality of the essay rather than relative rankings.
If the votes were hidden, I'm not sure which calculational scheme is best, yours or the current one.

Hi Daryl,
I think it is good that you are trying to come up with a constructive alternative, but I believe your proposition has a serious flaw.
If the ratings are based on running totals, by which I assume you mean just the total point value accumulated regardless of the number of voters who contribute to it, then those whose essays are voted on by the largest number of people automatically have an advantage.
For example, an essay that receives eleven 1's would then be ahead of an essay that receives a single 10. I think that is even worse than the current system.
If by "running total" you meant total points divided by the number of voters, then I cannot see how it is different from the current system.
Anyway, in my view the author voting feature should be totally gotten rid of. Then :
1) people would be more comfortable stating their honest opinions in the fora of other authors, they would feel more free to criticize the ideas of others without the consideration of possible retaliation, and that would ultimately facilitate a more productive exchange of ideas
2) the votes would be less likely to be influenced by friendship, lobbying or "celebrity" status (although I concede that the judges may not be immune to these types of bias either)
3) The fora would be less spammed with people who try to curry favor and lobby for their essays

I would have to agree that Daryl's idea is more agreeable than what is currently used. I also disagree with any type of repercussions since one of the aspects of this contest is to hopefully bring together disparate individuals who may be able to develop a like minded consensus. In other words, I would rank someone else's essay highly if I thought it pertained to the same problem I was espousing, and I see no problem letting them and other readers know that. I would like to be able to discuss their essay freely without worrying that perhaps I had crossed some arbitrary boundary.

What other value does it add to the discussion other than that it creates implicitly the proposition of a "deal"?

For instance, I think I remember someone writing that on Chris Kennedy's site awhile back, and I thought it was very genuine and a nice thing to have said. But as a smart person, wouldn't Chris infer, and possibly return the favour, just as he may if someone said "I gave you 10"? You might then think that words like "score" could be monitored, but then you get into liberty concerns, and FQXi might reasonably think that Google would have nothing to do with them.
Ed:
In a way (in an ideal world, apart from human nature) I agree; but mostly I have to admit that I found the "community rating" option both fun and useful---I wouldn't want to give it up. Of course it would have been somewhat disheartening when it became obvious that no one could hope to reach Ben, but it still would have been exciting in the same way to watch my own ranking flux locally, though less drastically.
With regard to Armin's remark that those who get rated the most move on even though they may not get 10s (yes, I do mean just add up all the scores; don't average them) I must reiterate that Ben managed to get way more votes than anyone else, even though he posted Aug 20---proof that everyone's got a chance to get the number of votes: if your essay's worth a 10 then it will quickly catch one worth 1 that's been getting ten times the votes. With regard to the concern about celebrity votes: I guess that's a price we've got to pay if we want to play with the big boys; that's one of the beautiful things about FQXi that we've all appreciated. I'd like to point out, though, in contrast, that e.g. Lee Smolin didn't enter an essay. There are good reasons for these guys to not enter an essay as well, and I think George Ellis has proven that, although he also proved to be up to the task.
Anyway, those are a lot of thoughts for now. Thanks to all who have commented so far. I think that ultimately we do need to find a way around the down-voting issue that doesn't take all the fun out of the contest.

Hi Daryl,
Thank you for your answers. I think under your proposition, the success in the contest becomes even more a matter of door to door soliciting, so I still do not think it is a good idea. Being able to persuade lots of people to vote for your essay to me should be unrelated to the merits of your work.
As for the repercussion issue, keep in mind, I strongly favor getting rid of the author voting feature, which would render this issue moot anyway.
Author voting sure has lots of benefits: It gives you a sense of control over the outcome of the contest, you can input your opinion quantitatively about the quality of other essays, it is exciting to see the essays move up and down the rankings and it is especially nice to hear lots of people complimenting your work and how brilliant your ideas are.
Unfortunately none of these are related to what this contest is supposed to be about: Identifying new ideas which can really deepen our understanding about nature. In fact, it actively undermines it. Honestly, would you tell someone they misunderstood something in their essay if you knew they could penalize you for it?
I guess our desire to be validated in many cases supersedes the search for truth.

Again, I don't think your anecdotes really address the issue that author voting poses a conflict of interest problem and tends to inhibit honest criticism in general.
You said: "I repeat: in the system I propose, the worst someone can do for your chances of getting to the finals is to not vote at all."
No, they can do worse by not voting for your essay and voting for other people's essays. I believe whatever system you propose, under author voting people will find a way to try to manipulate it to their advantage. Why not just get rid of this sociological baggage? Why is author voting so important to people?

Dear Armin:
"Again, I don't think your anecdotes really address the issue that author voting poses a conflict of interest problem and tends to inhibit honest criticism in general."
Actually I don't think I'm an anomaly. My anecdotes were supposed to show that many of us stated our critical opinions of the opinions of others. Eckard repeatedly remarked on this forum that he wouldn't compromise in stating his critical opinion, even if that meant more 1s. And his essay did make the list of finalists as well.
Also, you and I have disagreed on what might constitute a "better" system than the one that we had in this particular competition, but I'm glad to have your opinion and I find that I like you.
So I think that the word "general" should at most be replaced with "in some cases" in your above statement.
With regard to your final paragraph, I think community engagement is a good thing, because we're all trying to get our ideas heard, and I think community voting promotes that. If there wasn't community rating in this competition, I imagine a much smaller number of people would have read my essay, and in my opinion the ability to expose our ideas in a place where they will be considered is the most important aspect of this competition.
Best, Daryl

Hello Daryl 'n all,
I'd say the only drawback to adding, rather than averaging the community ratings, is that some essays would get more ratings than others, as Armin pointed out. All voting systems probably have drawbacks, and trying to fix that one might be the best of the alternatives. Some system of sending essays to authors to rate randomly might help improve it.
Best wishes, Jonathan
(PS. Or perhaps some combination of summing and averaging that is not known exactly to the voters, but which brings in the advantages of both.)

I favor keeping the voting system as it is. I favor keeping the rankings public.

Dear Brendan,
This is a great contest and FQXi should be credited for creating this public square where many diverse ideas can be exchanged. What makes FQXi so unique is its open and uncensored policy on posts and essays. The many important benefits from this policy far outweigh the few abuses. So we shouldn't seek to change things too much.
But here is a simple suggestion I feel will eliminate most of the voting irregularities many have complained about. Simply, while the community rating is going on, disable the 'community ranking' option. It's difficult to 'make deals' when you don't know who's up and who's down.

Thank you Constantinos for reminding us what is good about this particular contest.I agree with you that FQXi provides a great web site and the competition is another marvellous opportunity to present and talk about various physics ideas. In most other contests entries are submitted and nothing more is heard of them until winners are announced. Nothing is learned of the essays, or ideas in them, that are not presented as the winners.
For all its faults at least in this contest we can see the other entries and consider the ideas and presentation of them for ourselves. It also gives the opportunity to meet others who find our ideas interesting or have interesting ideas of their own and have enjoyable and maybe even fruitful conversations. I would really like the social aspect of the contest to somehow survive even if community voting is superseded.
Perhaps each week of the contest just 10 or 20 essays could be presented to the community, who can then discuss and vote on those particular ones. So on until all of the essays have been given the same amount of time for consideration by the community. Maybe community voting should be replaced too and only the ability to see and comment retained. Would it be possible to get on board a large panel of volunteers, from various universities, who are undergraduate and postgraduate students but not competitors in the contest? Their opinions, as well as those of interested but not competing FQXi members, could then be taken into account. IE scrapping author voting entirely.

Hi Georgina,
As in the last several posts I have vociferously criticized the author voting feature of this contest, let me to counterbalance those comments by stating explicitly that I completely agree with the point you made about this being "a marvelous opportunity to present and talk about various physics ideas" and that this is far better than what happens at most other contests.
I believe though that this exchange could be even better-possibly far better-if it was not hampered by the worry (or just even the fleeting thought) that any comment that might be negatively construed could result in one's essay suffering a drop in rating.
To me, the author voting feature is like a Trojan Horse. Yes, it stimulates additional engagement, but not the kind you really want in a scientific debate. It is nice to receive compliments, positive comments and so on, but how much do they really help you improve your ideas and grow, as opposed to a comment that points out a mistake?
If there was a an idea that was sure to inhibit this kind of feedback, author voting is it.

I also disagree with your assessment of the author voting system. As you are aware, in what I've proposed another author's vote---even a 1!---can only help someone get through to the list of finalists. So although peer assessment is flawed in the current system, it's not absolutely flawed.

The fact that you were able to have a "disagreement of sizable magnitude" with another person without it affecting the essay rating does nothing to refute the fact that author voting tends to inhibit honest criticism unless you can show that this statement is not true in general. Given what we know about human nature, I don't think you can.
I think most people are in favor of author voting for various emotional reasons, but it is in reality counterproductive if what you are trying to do is science.

You've gotten around the one major flaw I saw with the system I proposed: when the finalists seem finalised, someone might then cast a 1 to some top-rated essays in order to hurt their average in the final voting. I seems very conniving, but let's not underestimate the lengths that some will go to. If everyone gets a limited number of votes, perhaps determined from the total number, then the hope could be that they'd use them wisely.
Thanks!

Armin,
Just now saw your reply.
The counter to being able to tell someone exactly what score you gave their essay is that there must be a line drawn somewhere on what is appropriate and what is not. I would rather there be no line what so ever, then to have others start arguing about semantics of what someone posted and whether it was collusion. What you are proposing is a subjective evaluation on someone's intended meaning, and in my view would lead to many more difficulties than solutions. There are apparently very passionate arguments at the moment about final position within the contest. I have no idea of the merit of anyone's arguments, but also adding after the fact subjective evaluations of the postings on someone's essays would not seem to serve this contest.

Thank you Brendan and the fqxi staff for patiently putting up with all the problems generated during this year's contest. It was fun and instructive nevertheless with many fine essays, most (?) from new contributors.
I like Constantinos' positive comments and his idea that community ratings should not be visible until all voting is finished. But that will give undue importance to Public rating - so I think that should be scrapped altogether. I think Georgina's suggestion of only offering 10 or 20 essays at a time for voting suffers from the fact that one has to follow all these postings week by week, otherwise many essays will be unfairly missed. But I like Georgina's suggestion to:
"get on board a large panel of volunteers, from various universities, who are undergraduate and postgraduate students but not competitors in the contest?"- but why not professors as well?
Finally I agree with Armin's comments about community voting - but up to a point. I wonder if it would be useful to limit each contestant to a limited number of votes - perhaps 3, that can only be given at the end of the contest?

Hi Vladimir,
In this contest, my personal experience has been that, it has not been possible to review all of the essays - despite considerable effort. There are just too many and life goes on beyond the competition. So that situation wouldn't alter if just a selection of essays was presented each week.It wouldn't matter if all essays were not looked at by everyone, so long as a sufficient number of reviewers looked at them on any particular week.
It might be possible to have different categories each week, such as essays about relativity, essays about reductionism , essays considering the role of information and so on and then ones that don't fit easily into any other category. Reviewers could then choose to look at a number of topics that they are most interested in and in which they have more knowledgeable and possibly expertise.
You wrote in reply to my earlier suggestion "get on board a large panel of volunteers, from various universities, who are undergraduate and postgraduate students but not competitors in the contest?"- but why not professors as well?
It would be great if professors would want to be involved too. I just thought they might have less reason for wanting to be involved. A student might quite like to say on their CV that they have been on the independent essay selection panel for the FQXi contest in their spare time. They would probably be very happy with just a little FQXi button badge in return, I would have been as a student.

Vladimir F. Tamari replied on Oct. 8, 2012 @ 03:33 GMT
Hi Georgina
You are right - it is impossible to review them all - I read and rated about 80 essays.
Putting categories to essay may have advantages for allowing reviewers to choose which essay to read - according to your scheme. This however carries two problems - many essays cannot be easily categorized as they touch on many subjects, or perhaps 'new' subjects.
The other more serious problem in my view is that a reviewer who is a recognized expert in, say, Special Relativity, will have set views, and would not look kindly on essays that challenge SR. This would defeat the whole purpose of fqxi to break new ground.
I wonder what will next year's contest be about, and which of our rating suggestions, if any, will be adopted?
Another item to mention here is that it was not clear to me what the ground rules for promoting essays one believes worthy of such favor. I sent a group message recommending essays by authors I had introduced to the contest,but a friend told me that was frowned upon, so I stopped doing that.
Cheers
Vladimir

Hi Vladimir,
you are right about the possible (maybe unintentional) bias; however that happens whether the essays are categorised, or left as one muddled collection; leaving the selection of what to read / when entirely up to the reviewer. Another solution though might be to have different categories for different styles of writing rather than subject, that are shown to the community at different times. I think parts of the whole category would be best as too much of any one style might be difficult to cope with, and not be representative of the contest as a whole.)
Some feedback from the organisers to the community on what they thought was good about the contest and what they liked about the general conduct of the community would be good (I think that generally there was a great deal of good discussion and respect for other people's opinions). Despite the problems FQXi has still been fantastic hosting a competition of this size, where all of the essays were available and could be commented upon. That worked very well, at least for me. There was no trouble seeing any of the papers or being able to comment throughout the whole contest.A number of people have commented on their threads that they are not bothered about votes but are only in the contest to show and discuss their work.
I really think it important to concentrate on the positives rather than let the activity of a few spoilsports or cheats detract from such a brilliant and unique event. If there was other conduct the organisers did not like, other than voting irregularity, perhaps that could be highlighted as unwanted in the guidelines for the next contest.

As I wrote a few days ago above, there shouldn't be any voting at all. It's not that difficult to set up a refereeing system that isn't too much of a burden on the community here, I made a suggestion for that. That has the benefit that all essays end up being judged according to the relevant criteria, and the best ones will get an extra review by the expert judges.

What did Churchill say? Democracy is the worst form of government, except for all the others.
I have to agree with Yuri, that the technical workings left something to be desired.
The politicalization of voting has occurred in all the contests. I don't see any way to really separate it from voting for those with similar ideas, even if it seems like vote trading. Blocs happen.
Georgina had an interesting idea, further up the thread, about having different categories. What they might be might depend on what the next subject is. Have a couple of positive categories, like most focused on the subject, most original, then have an "ignoble," nuttiest idea category. That might relieve some of the attitude voting. Another might be a comprehensible/incomprehensible scale category.
Another idea might be to not make only those at the top of the list eligible for the finals and let the judges just use the community votes as suggestions. Then there won't be as much cutthroat competition to make the finals, but to make one's abstract as clear, convincing and interesting as possible.

To all:
Since some people have asked me for an alternative suggestion to author voting, let me mention as an example one procedure that I can think of here. This is not entirely an original idea, it is inspired by the procedure used to grade Advanced Placement essays.
One could assemble a group of preliminary judges, each of whom is assigned to a manageable number of essays. Each essay would be guaranteed to be rated by two preliminary judges, and if the ratings of the judges (given without the knowledge the other judge's rating) differ from each other by more than a certain amount, it would be read and rated in addition by a third preliminary judge. It would probably help to make the process more efficient if the rating scale was less differentiated, e.g. 1-4 or 1-3. Each group of preliminary judges would then submit the top essays in their group (the finalists) to the group of final judges who select the winners from the finalists.
As a concrete example, if one considers 30 essays a "manageable number" then for 270 essays this procedure would require somewhere between 18 (2 ratings/essay) to 27 (3 ratings/essay) preliminary judges. I have no idea whether it is within the ability of FQXi to assemble this number of judges, but it does not strike me as outlandish.
So here is a constructive suggestion in addition to my criticism.

Armin,
but who will pay for those judges work? I doubt there will be volunteers. It's a hard work.
The need to solicit ratings is not as bad, as you paint it, because it forces one to get involved with others in a positive way.
I think Daryl's idea is good. Also what John and Georgina suggested, categories of ratings, is a good idea and it would work with another type of a system from Daryl's.
Luckily, it is not up to us to make those hard decisions.

Well, peer review for journals for example is unpaid. Again, I have no idea how many judges can be realistically assembled and how many essays one can reasonably ask each person to rate. I used the 30 number based on the assumption that all the final 35 essays will be read by all the judges, and if that is correct, it would mean that they would consider that, at least, a manageable number. Having this sort of information available instead of having to guess would permit devising a system that fits within the given constraints.
But in any event, I tried to make the argument against author voting in the various posts above, and I believe the case is very strong, but you are of course correct, it is up to FQXi to make the call in future contests.
All the best,

This contest shows very good intentions of the sponsors, and at least of some of the organizers. It also gave the possibility to have interesting conversations about interesting ideas.
The problem of the human nature which is easily tempted to use the rating system in one's favor, and not to really rate the essays, was present in previous editions, and nothing was done to be fixed. One simple idea would be to have three groups, A, B, C, each with its own set of prizes, and A votes for B, B votes for C, C votes for A. This excludes the need to give bad ratings to others to promote oneself. It excludes or at least makes much more difficult the alliances, because you vote for someone who doesn't vote for you. Anyway, there are simple ways to make the things work, if wanted.
There are then the technical problems. It seems that some contestants found how to use the backdoors of the system, and cast multiple votes. If the programmers forgot to add a condition that the vote is unique per contestant per essay, this should apply to everyone. But only some people received this superpower. I think transparency is important, and detailed explanations should be provided. And who are those contestants who abused the system?

Sorry, the above was me, I thought I was logged in.
Let's stretch the benefit of the doubt, be nice guys and declare that the above mentioned problems were honest mistakes.
But what happens when Brendan gives us a list which he claims represent the status of the votes at midnight, and someone presents screenshots and saved pages right before and right after midnight, with a totally different situation? The pages I saved at midnight are in clear contradiction with Brendan's official and final statements. How is it possible that the evidence I presented simply be ignored?
Scientists should be guided by evidence, and their explanations should not contradict evidence, and to be falsifiable.
The system used in this contest is totally non-transparent, they give you no tool to falsify it. If they would want, they could change the votes as they want, and their explanation that hackers made you see the wrong votes would explain any change they may do.
And, when presented with evidence contradicting Brendan's official statement, the evidence is simply ignored. While we can understand honest mistakes, and unpredicted social dynamics at votes etc, ignoring evidence is more than this.

Dear all,
i thought about Armin's proposal with the judges. I think this would be again problematic, because as it is the human nature, one soon will doubt the ability of the own judges to have objectively judged the own essay (and presumably also other essays). *WE* must do this, if we want our claims and assumptions to be taken serious. How this could work, i will outline in the following:
My own idea is, that we as a community have to solve the problem - with the help of some new voting system. My idea for this as follows:
As civilized people, we must be forced by the system to behave as civilized people. This could be established by attaching at every posted essay a *commenting-AND-voting*-box for every essay contestant in the contest.
Before and essay deserves a "thumb-up" from the community (just a thumb-up as a flag that the essay should be under the 35 finalists and should be read by the judges and judged), at least 35 contestants must comment in their box, why they think the essay should be under the 35 finalists and then mark their "thumb-up" box.
I see two main advantages for this procedure:
First, one has to explain, to the essay contestant in question, why one thinks this essay should be under the finalists (or not). Second, for obviously trash-essays, no serious contestant would leave a comment in the box and highlighten the "thumb-up"-box.
Second, it would give a certain degree of TRANSPARENCE and would allow the contestants to more focus on arguments than on scores and placements.
For this to work, fqXi surely must assure that "trash-authors", "fake-authors" and such can't enter the contest. There should simply be a better control for the quality and integrity of an entry.
If this would be done, the community can more concentrate on discussing, if and why a certrain essay has deserved to come into the final group. If one or two votes for establishing the "thumb-up"-sign for a certain essay lacks, there would be more discussions on the issue of the content wether that essay should be a finalist or not.
Surely this all would partialy need a new implementation for the websites' voting system, but i think it can be done within some months and would be possibly also be of interest to the sponsors and fqxi itself - we must remember there is a huge amount of money involved in this contest!
We also must remember that we must act here as scientists and rational people which can argument their lines of reasoning for judging an essay, if we want to be taken serious. For that, we must solve our problems here in the group of those who are seriously interested in the advancement of new ideas, interpretations, insights, discoveries and so on. What could be more exciting?
I think if my combination of "thumbs-up"-voting and before that neccessarily leaving explaining comments for that decision could be realized, this would be as transparent on the group-dynamical level as it would be on the technical level.
Best wishes,
Stefan

Typically, in elections vote counts are not announced until the election is closed. In the US, TV stations can't even announce projections until the polls close. It is feared that partial results will affect later votes. This becomes even more worrisome if many of the votes are later invalidated as happened in this contest. I certainly would support keeping the ongoing rankings of the community voting secret until the voting is closed.

2. Is the voting for FQXi members mandatory or voluntary in the first round?
If it is voluntary, how to save balance between numbers of professionals and amateurs?
3. Lot of essays does not correspond to the criteria of relevant.
Among leaders of contest I see philosophical essays absolutely not common with topic of contest.

Dear All,
First of all I thank FQXi for the opportunity to share your ideas with other interested people, it is a unique way forme to be able to express myself.
This is the second contest forme, and as in the first I only rated the essays that I fully understood and thought that they deserved to be read by others, of course my rating does not influence that but it gives a little boost for the writer also.
Furthermore I did not give any low ratings, I think I am not the one to condemn anyone, if I don't agree with a proposal I say so in a post and await reaction.
I do not understand people who just give a 1 rating without leaving a post that they do not agree with the content of the essay, let them discuss first and perhaps then but anyway. (or make the ratings visible with the names, so that the author has defense)
If authors couls have this attitude it would be a lot easier also for FQXi, if they cannot we might need a new way of judging , I foresee in the next year even more participants, and then it becomes more and more difficult.
But I enjoyed reading all the new ideas.

I think that is possible the damage reduction of coalition between authors requiring a minimum number of vote for each author (for example greater of 20), so that each coalition is loser in the great number of votes.
I think that in the real world, in each - close or open - competition there are ever persons that trick, and I am sure that the majority of FQXi authors are knowledge lovers, without any intention to distort the competition.
This contest is a moment of reflection, idea exchange, partecipation; only a person win, and this don't change the life of a person.

Hi Folks,
I think this has been a great contest, but I am sorry that some folks were hurt by anomalies or voting blocs. I think the way that is handled could be improved. I tried to be ethical in my voting, but it is a demanding task! I knew I could not read 269 papers, but before I rated a single essay, I read at least 50 to get a sense of the relative quality. Then I deliberately sought to rate essays at every level of quality, from worst to best - attempting to rate all the papers I'd read, and read quite a few more - all during the final week. I gave no 10s, but I used every other number at least once, with most ratings in the 4 to 7 range.
I did not engage in any punitive or reward voting, but attempted to evaluate essays for both quality of ideas and presentation, with the highest grades going to those who fulfilled both aims exceptionally well. But I would have to say it requires a lot of effort to be absolutely fair with essay evaluation. Sometimes it requires considerable research or study! I felt it was my duty to make that effort, and I took time off to make sure I could get the job done in a timely manner, and still be fair. Some people do not have the time or freedom to do that, but I think we all owe it to each other to try to rate each other fairly.
Perhaps the best suggestion is that no rankings are posted until the following day, so we only see the final tally. That would defeat a lot of voting strategies designed to boost selected scores by trashing others.
All the Best,
Jonathan

AndyM wrote on Oct. 9, 2012 @ 07:05 GMT
I have a simple scheme for future contests. Each contestant gets to pick a limited number of essays, say 3 that they feel are the best. Each essay chosen by the contestant gets one point. Perhaps commenting on why that essay was chosen should be included, to help others understand the value of a chosen essay. The 35 (or whatever number) essays with the most points would qualify for the next round.
In this scenario, there would be no down voting anyone's essays. The limited number of points that each individual could award would inhibit collusion to some extent.
There would still be a popularity contest, but perhaps FQXI members' votes could count more (say each vote would be equal to three votes of others) in order to allow for a professional skew.
As a non-contestant, I have enjoyed reading the essays, but feel bad for the contestants whose essays were in the top 35 at some point, but then fell out of contention. Many were deserving of consideration.

Brendan,
Authors ranking essays is a unique and valuable feature of fqxi contests. We should not change it or limit it. The problem is, imho, authors may not always know what essays are “best”. Hard to judge this over such broad and often technical topics. Rather, I suggest authors rank essays according to which essays they think “merit” further consideration and want to support. But “average rank” may not be the best and most effective way of determining such final group. “Averaging” often leads to wild and extreme swings in ranking, 'vengeance voting' by bringing the average down, vote trading and other abuses. An essay ranked in the top 35 can drop to below 100 with one extreme low ranking if the number of votes is small. And the other way around. We've seen this happen repeatedly in this contest. Further, the “average” does not account for the number of people that took the time and effort to read and rank an essay. Essays that make the final cut with just a few votes may not “merit” further consideration as much as an essay that gets many votes but has lower average, with extremes of high and low ratings.
Here is what I would like to see.
1)The 'community ranking' order be disabled during the period of community voting.
2)Community ranking be based on the “sum” of points an essay earns rather than the “average”. That way all ratings can only positively add to the total and the worst anyone can do is simply not rate an essay.

Constantinos - I agree to keeping the voting results secret until the voting period is over. However using the sum of votes as a criterion will only increase the pitch of all-out 'vote-for-me' campaigns that mar the discussions of the physics itself on many pages. At one time, seeing the practice was rampant, I started sending such electioneering messages on behalf of new essayists I had introduced to the contest, but stopped when a friend noted that that may be frowned upon.

Constantinos:
I agree with this. I proposed using a sum rather than an average in a post above, and quite a few people agreed that would be a better system than an average, as it would disable people's ability to vote *against* others' essays, which we all saw happen with the 1s flying about on the last day. I like the idea of the community ranking being based purely on how much *for* an essay other people were.
I've argued here that I found the "community rating" order both exciting and useful; but after some discussion and thinking I agree that it should be disabled in the future. That will also be exciting.
Ms Vasilyeva made what I considered another excellent suggestion above, which I see AndyM has now proposed as well and many have agreed with: limit the number of votes that anyone can cast---say to 30 or 40, judging from the number that were cast in this contest, but maybe only 20---enough that people are going to be sure to use each vote wisely.
I think it would be great if FQXi would organise a questionnaire for all contestants to fill out, giving options such as these for us to vote on, and take these opinions into consideration for the next contest.

Dear Administrators,
I suggest you checking how the ratings evolved during the last day essays could be rated. If you look to essays that were top ranked on the day before and see how their ratings evolved during the last day, you will see and abrupt change on all ratings, a change that makes no sense, a statistical error.
You have chosen a rating system that is very simple but can be strongly affected by people’s bad intentions. For this system to work you must introduce techniques for filtering these “statistical errors” or choose another rating system.
My essay was in 20th -15th place during the last days and it was in 15th about Friday at midday. When the rating were finished, it was about 50th !!
Do you believe this fall is justified? Do you think it is fair?
It happened not only with me, but with many others. So I question you all: do you think the top ranked essays are really the top ranked ones?
That will be the worst wrong assumption of this contest. The very foundations of this contest went down on the last voting day…

Dear All,
There are many good and thoughtful ideas here. FQXi cannot be expected to foresee and prevent every possible variety of bad behavior, but I think that the constructive suggestions offered here for possible improvements are helpful.
Armin’s major concern seems to be the scientific integrity of the contest, and of course he’s right that author voting introduces a large sociological element. An author with an idea whose scientific value is many times that of all other entries combined, but who is unknown to the other participants and FQXi members and who does not interact very much, will have no chance of advancing. Three or four of my 10’s were in the bottom half of the rankings.
However, the scientific ideas themselves are only part of the equation, as the guidelines for the contest make clear. Another major aspect is discussion and communication of these ideas. The authors are asked to submit essays that are “original and creative, technically correct and rigorously argued, well and clearly written, and accessible,” and they are “strongly encouraged to cultivate a supportive atmosphere of scientific conversation rather than a judgmental atmosphere of critical scoring and evaluation.” I don’t think it’s supposed to be like refereeing a journal article, which might be 70% equations and of which only 100 people in the world can understand more than the title. My understanding is that it’s explicitly against the intent of the contest to go around shooting down others’ ideas. That is part of the reason why the low final values of the average ratings annoy me a little. Wilhelmus expressed this too. Well-developed, meticulously presented ideas of potentially fundamental importance rated 4.2 out of 10? Really?
In any case, the sociological aspect seems somewhat self-limiting. Schmoozing on others’ threads can only get one so far. The authors here are not fools, especially when it comes to their own ideas. They can tell if you have made an honest effort to understand their work. The best way to induce others to consider your ideas is to consider theirs first; you might even learn something! I read most of the essays more than once; I didn't manage to discuss them all with the authors, but I learned a great deal. Although I appreciate Yuri’s remark about the reluctance of some of the authors to engage, I think that active participation confers an adequate advantage naturally. However, FQXi knows that eliminating author voting would eliminate one of the major motivations for interaction. Armin believes, quite rightly, that this interaction is a bit constrained because people are afraid to step on others’ toes, but understanding others’ ideas cannot be faked. This provides an incentive to learn, which in my view is the best thing about the contest.
I’m reluctant to propose anything about the specifics of the voting, since I’ve only been here a couple of months and no one likes an opinionated neophyte. However, I like a lot of the ideas that have been offered by others. I agree with the majority that author voting should be retained, but modified. I agree with Daryl that the ratings should be summed, rather than averaged. I agree with Constantinos and Jonathan that the community rankings should be hidden, to remove the incentive to bomb high-ranked essays and the stigma of being far down the list. This also goes along with Joseph’s remark about the influence of partial results. I agree with Domenico that the minimum necessary number of votes should be increased, since this encourages interaction and accessibility. I agree with Vladimir that the public ratings should be scrapped; I believe these were used almost solely to inflate or to bomb. I think maybe there should be a 24-hour period between the close of voting and the announcement of results to make sure everything is straightened out and to prevent the disappointment of seeing essays drop below the cutoff. If AndyM’s idea of limiting the number of votes is employed, I’d suggest opening voting only after all entries are submitted, to prevent votes being “used up” too early. I agree with Stefan that above all we must try to be civilized! Take care,
Ben

Ben :
I fully agree with you and would like to add :
An essay has to be accepted by FQXi, so in my opinion FQXi does not admit essays that are not in line with their directives. The first essay last year that was accepted for publishing gave me already a "great" feeling.
So if people are giving 1's as rating they deny the first selection of FQXi.

Greetings everyone -- there are so many comments, I unfortunately can't reply to them all. Let me focus on three things.
First of all, I just want to say thank you again to all of the participants. And also thanks to everybody who took an interest, came to the website to read essays and possibly leave comments. This was the largest contest by far. We obviously have some growing pains to work through, but I hope everyone will be back to make the next contest another intriguing, exciting, and educational event.

Second...I see that several people are still understandably confused about final shifts in rankings around the end of the voting period. Let me summarize again what happened.
First off, though, I have to point out that even when only legal, fair voting occurs, there will be large shifts in the rankings towards the cut-off. This is due to the large number of voters rushing to put in their rankings before the deadline. I haven't counted the numbers, but considering that over half of the essay entries arrived within 24 hours of the entry deadline, I assume something similar occurs with the voting.
Having said that, we had an issue with invalid, duplicated votes. Fortunately, it was easy to spot these votes in the records and to remove them. Unfortunately, we did not have time to find the hole in the system, and invalid votes continued to appear up until voting closed. We therefore had to periodically recheck the records and clean out invalid votes.
On the last day of voting, we did several of these cleanings. In particular, we cleaned out the invalid votes just after midnight, after voting had officially closed.
We then had to do another, final cleaning later that day. This was due to another technical oddity, which enabled voters to place votes after the deadline. People did place votes, so we had to go back and purge these late votes before declaring the results final.
Every time we cleaned out the invalid votes, there were sudden shifts in the ratings. As a result, people may have noticed sudden shifts during the last day of voting, a sudden shift immediately after voting closed, and another sudden shift the following morning.
The large shifts in rankings, then, were due to a combination of the expected shifts due to lots of last minute votes and the sudden shifts due to cleaning out invalid votes.

The final rating is invalid, Brendan Foster, even if your story is the true one. Voting should be repeated - it will take a day or two.

Brendan Foster,
You will have to prove that these three votes were invalid. Your silence shows otherwise - they were valid but someone else, not Stoica, was chosen to be a finalist.

Hi Brendan,
thank you for explaining. It was perturbing to see that the positions were still altering long after the deadline. It has been suggested elsewhere in this thread that in future there should be a delay between end of voting and final list presentation.I think that's a really good idea. To avoid unnecessary stress to the participants, it might be good to remove the list entirely in that interim period. When last minute votes are added on and invalid votes are removed, after the deadline but before the final list appears.

Pentcho, Cristinel,
A screenshot is not evidence. I can take a screenshot today and say you that was taken Friday at midnight.

Anonymous,
I'm answering now because I was traveling, as I wrote on my thread.
I showed the evidence I have, and this is what I saw. Not only screenshots, but also files. There are some timestamps in the files too. Why don't you show the evidence YOU have? They can easily be checked by FQXi, with their database. Brendan said that someone rated me extra times, so he removed from my votes three tens. Why he doesn't say who did it? Also, how comes that the same hackers used extra votes to downvote me with 50 positions two days earlier? Why did they give me ones, and then tens? And why did not he remove those extra downvotes, as he claimed will do? After he claimed that everything is OK, I was still down, and I climbed slowly to the 9nt place, then in few hours to 13, and in few minutes to 23. Then, in one minute after midnight, three votes of 9 or 10 were removed from me. not added, removed.
Obviously there were big problems at this contest, which don't prove transparency, ability in managing such a project, or fairness.
If they are fair, they should release the data they have. They can make public the database, and they can remove the names of the voters to protect their anonymity. But they should say who are those who voted repeatedly and who voted after closing.
I presented my evidence. FQXi proved to me indubitably, for the second time, how fair this contest is. I saw at the first contest, but I continued to come because of the nice and smart people I found here. I apologize to them that I will no longer accompany them at the future contests organized by FQXi.

Cristi,
My evidence is that screenshots and files pulled from your computer are not evidence. There was no hackers (read Brendan's posts), but a bug in the software allowed some people to vote multiple times. If a friend of yours gave you three votes of 9 or 10, why do you think that the votes would not be removed? Are you special?
I agree with Pentcho, "your thoughts would be entirely different if you were still #23". Everything was ok for you (you wrote "OK") when you believed that you were a finalist. Now you make bold claims about something that supposedly happened years ago. You do not give any evidence, but you write "I continued to come because of the nice and smart people I found here. I apologize to them that I will no longer accompany them at the future contests organized by FQXi." If you are being sincere, you would admit that the nice and smart people will continue being here in future contests.

Who could be the silly friend giving three votes after midnight, thereby exposing him/herself as an obvious cheat? Why is Brendan Foster silent?

Sorry I was mistaken: the three votes were REMOVED after midnight but given before that time. Still my point is valid: only an extremely silly "friend" would give three votes of 9 or 10 to Cristi.

Anonymous,
Cristinel has good reason to feel disappointed, unfairly treated and hurt. I don't think he should be criticised or made to feel bad about that. Although it would be nice for Cristinel and others who feel unfairly treated to have special consideration I think, upon reflection, FQXi have made the right decision to stick by the rules they set out at the beginning. As to change them at the end of the contest would send out the wrong message i.e. 'what we tell you is not necessarily what we are going to do and we can change it however we want according to what happens'. That would be bad for confidence in future contests.
Any blame for the disappointment and hurt felt because of the unfair manipulation of voting, and putting that damage right, rests with FQXi members or community who chose to vote outside of the spirit of a fair contest.Those who took advantage of software problems just to cause trouble, or bring the FQXi contest into disrepute, or to unfairly penalise or benefit certain essays to their own or other' advantage. Rather than just bringing the problem immediately to the attention of the FQXi admin. Those people who continued to vote after the deadline knowing that those votes were invalid and should not count in the rankings. Anyone else, contest participants or not, manipulating the rankings by hacking if such a thing happened.
It seems unlikely to me that any of that unscrupulous behaviour was orchestrated by the FQXI contest organisers. They have instead worked hard to counteract the disruption and unfair manipulation of the voting and should be thanked for that.

This is unlikely. Multiple voting or voting after midnight is too dangerous - I cannot imagine a sane person, even the most dishonest one, risking his/her reputation in this way.

Penctcho,
I have enough experience of human nature to know that people do not always do the right thing and some will take advantage of any opportunities that present themselves, even if doing so is unfair or unkind to others. The prisons would be empty and there would be a lot less heartbreak in the world if everyone always did the right thing. Life is not fair and there comes a time when each of us has to realise that and get over it.
