Essay AbstractThose wanting to realign science with our democratic and ethical ideals often challenge the view that physics has some unique status among the sciences, rejecting the claim that it is fundamental. The thought is that the privileging of certain theories as fundamental grants them a status that then allows them a free pass to funding, even in the absence of inductive support. I argue that properly construed, the claim that physics, or some part of physics, occupies a fundamental status is both theoretically reasonable and ethically defensible. However, a plausible understanding of the fundamentality of physics must move beyond interpretations of fundamentality as a kind of explanatory completeness. No present physical theory explains everything, nor is there a good argument to support the claim that any future physical theory will. Nonetheless, there is a significant kind of explanatory power we can claim even for our current physical theories, and this yields the sense in which they are fundamental. This notion I propose of fundamentality as explanatory maximality underwrites two compelling arguments for the continued support and development of research projects in physics, demonstrating that the claim that physics constitutes a fundamental science should be an important element of a vision for twenty-first century science.

In my view, we should answer this call to ensure our view of science and science
policy lines up with our values.1 And this involves recognizing that our views on the
question of whether one theory or another is fundamental may be used to motivate
policies concerning the allocation of resources. The claim that a certain theory or branch
of science is fundamental has a kind of power. But properly construed, the claim that
physics, or some part of physics, occupies a privileged status, thus earning the honorific
‘fundamental’ is both theoretically reasonable and ethically defensible, or so I will argue
here. So we shouldn’t shy away from making the claim that at least certain parts of
physics do constitute a fundamental
I.e. I see this in your essay and I ask if it is commensurate with a protocol of data analysis as you visualize it?
You can view my essay at December 21, and I would welcome your observations as to purported ethical issues there as well!!

Dear Andrew,
Thank you for reading my paper.
Did you have in mind a kind of data analysis that might be incompatible with the framework for discussing fundamentality I propose there?

Dear Alyssa Ney,
Many participants in these contests are retired professionals, physicists and otherwise. In view of the nature of FQXi since its founding, politics of the establishment versus 'outsiders' is baked into the cake.
Those participants such as yourself, still employed in Academia, are exposed to a whole different order of politics, which the rest of us have little contact with. Thank you for exposing us to this aspect of 'fundamental'.
I agree that 'explanatory completeness' is almost certainly the grounds on which the war should be fought, both in FQXi and in Academia. I also agree with your emphasis on 'near' physics, as opposed to "
truly fundamental theories [that] are merely idealized or several millennia away." You then wisely shift the burden from '
explanatory completeness' to '
explanatory maximality'. If this could somehow be quantified, it would probably serve FQXi well also, but the act of quantifying it would almost certainly generate another political war.
For an example of a war that's been fought for over a century, I invite you to read my essay.
Thanks for an enlightening read,
Edwin Eugene Klingman

Dear Edwin,
Thanks so much for reading my essay.
That's a great point that my proposed move from completeness to maximality introduces questions that would not otherwise be raised. But given that no (as you put it, near) theory is complete, if we are going to assess theories for fundamentality, then these are questions we ought to address. There seems to me nothing wrong with there being multiple criteria of explanatory power our best theories may meet, but we should have a clear means of justifying those we claim to underwrite the importance of continued support for physics.

Dear Professor Ney,
Thank you for your beautiful essay, which I very much enjoyed reading!
I wanted to add a couple of remarks relating to how governments view funding for fundamental physics research, especially in the Indian context. I think physicists will agree that the turn-around time from a great physics discovery to its possible applications (if any) to technology is quite long. On the scale of many decades, if not a century or two. This is true for Newton's mechanics, as well as Maxwell's electrodynamics, and even for quantum theory. Since governments want immediate feedback/benefit, say on the scale of five to ten years, we physicists have a hard time convincing them of the relevance of fundamental research. This is particularly true for a developing country like India, where the government desires its fundamental researchers to do that research which contributes to nation-building.
Also, and this is hard to grapple with, when dealing with governments, fundamental research is driven by curiosity, and its long-term impact benefits all of mankind, not one particular nation state. The concept of nation states runs contrary to basic research, with the former being self-limiting, and the latter global. Governments might be all too ready to borrow technology from other nations, and let the bright people of those countries do basic research, and ask its own smart folks to focus on immediate benefits for one's own country men and women. If every government took that attitude, no fundamental research would get done. Some governments might treat curiosity driven research as a luxurious past-time! An ideal world for research would be a one-world government, a utopia!
I had a couple of minor quibbles :-) While dark matter particles have not been found, nor are there any theoretical candidates, I would not use this as an example to say that hence physics cannot explain everything :-) As we know, the observations show non-Keplerian / flat galaxy rotation curves: these could be explained by postulating dark matter, or by modifying Newton's law of gravitation, as for instance in MOND. I would say the problem is very much open, and is a fascinating one for current research, but I am certain one day physics will have an explanation for it.
On a futuristic note, I am not sure if causality will survive in a quantum theory of gravity. Time, as we know it in present day quantum mechanics, is a problematic concept. It is classical, and as such classical entities should not have any place in a satisfactory formulation of quantum theory. Various arguments suggest that trying to put together quantum and gravity takes away the causal nature of events.
Thanks once again, for a brilliant thought-provoking essay.

Dear Tejinder,
Thank you for reading my essay and for these wonderfully rich comments.
First I want to say that I was not trying to suggest that physics will not be able to explain dark matter. I believe that it will. I used dark matter to illustrate a case in which we are led to the postulation of a new kind of entity different than others that are well-understood. It's true that those preferring MOND would not view the situation this way, but the other mainstream proposals for dark matter do take it as a kind of nonbaryonic matter.
The points you bring up about the motivations nations have for funding physics research are well-taken. This is exactly why I think we need to do a better, more perspicuous job of stating the importance of basic research in physics beyond mere satisfaction of curiosity. Your comments make it clear that it is important to pursue arguments that are not merely clear and compelling, but also that will appeal to individual nations rather than only society as a whole, at least given current structures of funding. This is something I will think about more.

Heinrich Luediger wrote on Jan. 30, 2018 @ 11:07 GMT
Dear Alyssa,
thanks for an encompassing postmodern view of science and physics in general. The shift from laws and causation to models and explanations in the early 20th century was the first of many truth-deflationary steps taken in the sciences which eventually led to the plain denial of theory (e.g. by R. Rorty) in favor of plain pragmatic temporalism, i.e. experimentalism. And today even the conservation laws of physics are no longer regarded as sacrosanct by some. That is, truth-deflation removes constraints and thus allows the introduction of ‘values’ into what once was a rigid, self-contained science. Although I entirely disagree with ideas of physicalism (the world isn’t vertical, but horizontal), your proposal of ‘explanatory maximality’ is another truth-deflationary step suited to align physics to the unbound creativity of the social sciences.
Heinrich

Dear Heinrich,
Thank you for reading my paper.
I don't view my project as taking another step toward deflation, but rather as trying to move the pendulum back a bit in the other direction. While we must recognize the truth in late twentieth-century critiques of reductionism, such as the fact that there are no explanatorily complete physical laws, there is an important sense in which physics does occupy a special status among the sciences. We simply need to state this sense in an accurate way.
That said, there is room in this position for, as you put it, the unbounded creativity of the social sciences. I try to address this in another paper of mine "Physicalism, Not Scientism" I have available on philpapers.org. It is coming out later this year in an Oxford volume on Scientism.

Alyssa,
Physics studies our experience of the universe, but the universe is not made of experience. It is made of real stuff. This is a reversal of the objective - subjective points of view. All that we think is objective we make up ourselves as experience. The object of this experience (underlying reality) is in fact what is real (objective = object).
As far as the OBJECT is concerned, “substance” and “cause” or what the universe is made of and what motivates its spontaneous evolution is out of reach of physics, by definition, and out of metaphysics menu, by ... ignorance, choice, .... (take your pick).
Best of luck,
Marcel,

Dear Professor Alyssa Ney,
FQXI is clearly seeking to find out if there is a fundamental REALITY.
Reliable evidence exists that proves that the surface of the earth was formed millions of years before man and his utterly complex finite informational systems ever appeared on that surface. It logically follows that Nature must have permanently devised the only single physical construct of earth allowable.
All objects, be they solid, liquid, or vaporous have always had a visible surface. This is because the real Universe must consist only of one single unified VISIBLE infinite surface occurring eternally in one single infinite dimension that am always illuminated mostly by finite non-surface light.
Only the truth can set you free.

Hello Alyssa,
You wrote: "No present physical theory explains everything, nor is there a good argument to support the claim that any future physical theory will".
You may be interested in the explicit "falsification" of this statement, containing both the "theory" in question and its "good argument", in
my essay here and references therein (see also
my web page). I am not trying to impose anything, but the provably complete, mathematically rigorous and multiply verified theory I propose provides essential reinforcement for your conclusions. I also like the spirit of realism and logical sense in your approach.

Dear Alyssa Ney,
thank you for your interesting essay, you offer some goods points to think about!
I was wondering how you dismiss the possibility of emergent properties that physics can't explain: do you suppose that it doesn't matter as long as physics has "the greatest degree of scope, accuracy, and precision of all theories that have so far been formulated?"
Moreover, couldn't this definition be circular, since "scope, accuracy, and precision" are parameters that perfectly suits physics? We could (for example, it's not my opinion) tell that religion X has maximality because it has "the greatest degree of comfort, simplicity and holyness of all theories that have so far been formulated".
all the best,

Dear Francesco,
Thanks for reading my essay and for these questions.
I don't dismiss the possibility of emergent properties in this paper. My only discussion of emergence in this essay is to warn against conflating emergence with reduction.
As for whether my interpretation of what it means to say physics is fundamental is circular... The focus on scope, accuracy, and precision, as opposed to comfort, simplicity, and holiness, comes from my interest in providing a sense of fundamentality that can underwrite the arguments for support of physics. A theory that is comfortable, simple, and holy may have benefits for some purposes, but I don't see how these characteristics would translate to making that theory more useful for developing new technologies.

Just letting you know that I am making a start on reading of your essay, and hope that you might also take a glance over mine please? I look forward to the sharing of thoughtful opinion. Congratulations on your essay rating as it stands, and best of luck for the contest conclusion.
My essay is titled
“Darwinian Universal Fundamental Origin”. It stands as a novel test for whether a natural organisational principle can serve a rationale, for emergence of complex systems of physics and cosmology. I will be interested to have my effort judged on both the basis of prospect and of novelty.

tml
I request you to please have a look at my essay also, and give some of your esteemed criticism for your information……..
Dynamic Universe Model says that the energy in the form of electromagnetic radiation passing grazingly near any gravitating mass changes its in frequency and finally will convert into neutrinos (mass). We all know that there is no experiment or quest in this direction. Energy conversion happens from mass to energy with the famous E=mC2, the other side of this conversion was not thought off. This is a new fundamental prediction by Dynamic Universe Model, a foundational quest in the area of Astrophysics and Cosmology.
In accordance with Dynamic Universe Model frequency shift happens on both the sides of spectrum when any electromagnetic radiation passes grazingly near gravitating mass. With this new verification, we will open a new frontier that will unlock a way for formation of the basis for continual Nucleosynthesis (continuous formation of elements) in our Universe. Amount of frequency shift will depend on relative velocity difference. All the papers of author can be downloaded from “http://vaksdynamicuniversemodel.blogspot.in/ ”

Alyssa,
Your students in “Understanding Scientific Change” may be inclined to support research in physics and cosmology if they see a very real parallel between what may be the last signals from technically advanced beings millions of light years distant and the size and distribution of planets in our own solar system. I am not aware of any proposed research project asking for government funds to analyze “Gamma Ray Burst Light Curves” with the thought in mind that the multiple peaks in many GRBs may correlate with the mass and distance between planets in distant planetary systems. The students and “hypothetical” funding agencies should know that the length of a gamma ray signal corresponds to the size of the source. That is, a gamma ray pulse from a “Hydrogen Bomb” is very short. But the pulse from a small planet converting to energy would be on the order of the time of a light pulse traveling the diameter of the planet. And it is easy to see that many Gamma Ray Burst Light Curves match with a light speed shock wave radiating across a hypothetical star/planet system. Would WE want to know that self annihilation by “gamma ray photon torpedo” was common in the Universe or would WE collectively prefer to “see what happens?”
That said. It would be nice if more people realized basic research results in unexpected value in many ways.

Dear Alyssa
If you are looking for another essay to read and rate in the final days of the contest, will you consider mine please? I read all essays from those who comment on my page, and if I cant rate an essay highly, then I don’t rate them at all. Infact I haven’t issued a rating lower that ten. So you have nothing to lose by having me read your essay, and everything to gain.
Beyond my essay’s introduction, I place a microscope on the subjects of universal complexity and natural forces. I do so within context that clock operation is driven by Quantum Mechanical forces (atomic and photonic), while clocks also serve measure of General Relativity’s effects (spacetime, time dilation). In this respect clocks can be said to possess a split personality, giving them the distinction that they are simultaneously a study in QM, while GR is a study of clocks. The situation stands whereby we have two fundamental theories of the world, but just one world. And we have a singular device which serves study of both those fundamental theories. Two fundamental theories, but one device? Please join me and my essay in questioning this circumstance?
My essay goes on to identify natural forces in their universal roles, how they motivate the building of and maintaining complex universal structures and processes. When we look at how star fusion processes sit within a “narrow range of sensitivity” that stars are neither led to explode nor collapse under gravity. We think how lucky we are that the universe is just so. We can also count our lucky stars that the fusion process that marks the birth of a star, also leads to an eruption of photons from its surface. And again, how lucky we are! for if they didn’t then gas accumulation wouldn’t be halted and the star would again be led to collapse.
Could a natural organisation principle have been responsible for fine tuning universal systems? Faced with how lucky we appear to have been, shouldn’t we consider this possibility?
For our luck surely didnt run out there, for these photons stream down on earth, liquifying oceans which drive geochemical processes that we “life” are reliant upon. The Earth is made up of elements that possess the chemical potentials that life is entirely dependent upon. Those chemical potentials are not expressed in the absence of water solvency. So again, how amazingly fortunate we are that these chemical potentials exist in the first instance, and additionally within an environment of abundant water solvency such as Earth, able to express these potentials.
My essay is attempt of something audacious. It questions the fundamental nature of the interaction between space and matter Guv = Tuv, and hypothesizes the equality between space curvature and atomic forces is due to common process. Space gives up a potential in exchange for atomic forces in a conversion process, which drives atomic activity. And furthermore, that Baryons only exist because this energy potential of space exists and is available for exploitation. Baryon characteristics and behaviours, complexity of structure and process might then be explained in terms of being evolved and optimised for this purpose and existence. Removing need for so many layers of extraordinary luck to eventuate our own existence. It attempts an interpretation of the above mentioned stellar processes within these terms, but also extends much further. It shines a light on molecular structure that binds matter together, as potentially being an evolved agency that enhances rigidity and therefor persistence of universal system. We then turn a questioning mind towards Earths unlikely geochemical processes, (for which we living things owe so much) and look at its central theme and propensity for molecular rock forming processes. The existence of chemical potentials and their diverse range of molecular bond formation activities? The abundance of water solvent on Earth, for which many geochemical rock forming processes could not be expressed without? The question of a watery Earth? is then implicated as being part of an evolved system that arose for purpose and reason, alongside the same reason and purpose that molecular bonds and chemistry processes arose.
By identifying atomic forces as having their origin in space, we have identified how they perpetually act, and deliver work products. Forces drive clocks and clock activity is shown by GR to dilate. My essay details the principle of force dilation and applies it to a universal mystery. My essay raises the possibility, that nature in possession of a natural energy potential, will spontaneously generate a circumstance of Darwinian emergence. It did so on Earth, and perhaps it did so within a wider scope. We learnt how biology generates intricate structure and complexity, and now we learn how it might explain for intricate structure and complexity within universal physical systems.
To steal a phrase from my essay “A world product of evolved optimization”.
Best of luck for the conclusion of the contest

Fundamental physics, real physics, has helped other disciplines as chemistry, biology, or medicine. Many tools developed for particle physics have no applications on medical diagnose of diseases.
"Physics thus enjoys a form of constitutive explanatory completeness: all entities are either physical or have a complete constitutive explanation in terms of the entities of physics". No. This is confounding the substrate with the discipline. All matter is made of elementary particles but this doesn't imply all is reduced to physics. Physicists as Weinberg studying elementary particles in an accelerator are making approximations don't apply to particles inside a living cell. As a consequence properties of a cell aren't described by the formalisms developed by physicists as Weinberg. It is also worth to mention
emergent properties. A given collection of particles forming a macromolecule, a living organisms, or a social group have a set of properties that don't exist on the inferior levels. So an physicist can be studying particles during centuries without discovering those emergent properties that only exist on the more complex levels.
"Fires, heart attacks, and mass rallies all require the influx of oxygen". Sure, but the failire here is on believing that "oxygen" means the same in all instances when it doesn't. In atomic physics oxygen can be represented as a sphere, because an isolated atom is spherical. Oxygen in the watter molecule is radically different. Attached is a 3D draw of an oxygen atom in a H20. The atom boundary has been obtained by QTAIM computations. So one can study atomic oxygen and know nothing about the properties of oxygen in a molecule of water.
"And all effects, when the demand for explanation is traced out far enough into the past, find nothing other than explanation in terms of early physical features of the universe". But this is assuming a deterministic conception of Universe.
"The Einstein field equations hold for classical, i.e. nonquantum systems, the Klein-Gordon equation for free, i.e. non-interacting quantum fields, and t here is neither a general equation holding for all relativistic quantum systems nor for all types of free particles, let alone particles that interact; nor is there a patchwork of principles we might stitch together to cover all regimes." This is an excellent summary of current mainstream physics.
"A natural response to these points about the current explanatory incompleteness of physics is that when it is claimed that physics is complete, it is not being claimed that any current physical theory is able to explain everything, but rather only that some future physical theory we can expect to reach on e day will have the resources to provide a complete class of both causal and constitutive explanations". And stuff such as emergent properties will guarantee that any theory developed by physicists cannot describe the properties of chemical, biological or any other kind of high-level structured matter.
