Essay Abstract

What is more fundamental: geometry or physics? All classical physics before special relativity was based on the Euclidian geometry. In that sense one may conclude that geometry is more fundamental. However, great Riemann clearly understood that only our experience in physical world is the source of all our geometric constructions. Due to Einstein, the Maxwell electrodynamics lead to the pseudo-Euclidian geometry of the spacetime and the relativistic generalization of the Newton's law of gravity lead to pseudo-Riemannian spacetime structure. I will discuss here the following question: what is the fundamental geometry in quantum physics?

Dear Peter

Thanks for this effort. I struggled to understand your core argument, though your conclusions seemed reasonable. You may feel the same about mine...https://fqxi.org/community/forum/topic/3041 but may be able to further develop the geometry of my work and apply your understanding of symmetry to my model.

Best wishes

Dear Stephen, thanks for you comments!

I would like to know what were difficult to understand in my arguments?

Please be very concrete, since it is import for me!

I'm busy now, but I will read your essay ASAP.

Dear P. Leifer, fundamental should be simple and clear. So it is in quantum physics, you can declare, but not to find. The principle of identity of space and matter Descartes is simple, but not perceived by physicists because of their conservatism. Formulating principles of New Cartesian Physics, I made a number of discoveries that are outlined in his essay. Read it and try to understand. In this regard, I would like you to have closer contact.

Sincerely, Dizhechko Boris Semyonovich

Dear Peter Liefer,

I very much enjoyed your essay and agree with your postulates and many of your conclusions. Since, as you note, "we have lost the understanding of quantum theory", you picked a difficult topic.

One might ask whether a Cartesian coordinate frame with variable energy density can be equivalent to an "empty" void with variable geometry: regions of high energy density map into regions of higher curvature.

As you note, Einstein claimed Maxwell electrodynamics led to pseudo-Euclidian geometry of space-time, and "the connection with Minkowski space [is definitely needed] for agreement with experiments". But the experiments deal with relativistic particle physics and are inherently energy-based. You then note that "that initial assumption about Minkowski space-time structure […] was too simple."

Your conclusion is QFT and SM and their initial postulates may not be treated as fundamental. There is not enough detail in your essay for me to understand your QR (quantum relativity) but I will try to read your references.

My own essay contends that the "agreement with experiment" is based on relativistic particle physics and is an energy-time phenomenon, not a space-time phenomenon. I review the history of Einstein's analysis of Maxwell electrodynamics in the context of Hertzian electrodynamics which Einstein references in his 1905 paper. As this is relevant to the Minkowski formulation, it might be of some interest to you. I hope you will read my paper and comment on it.

My best regards,

Edwin Eugene Klingman

Dear Edwin, thanks a lot for you kind reply!

I try to understand (with big difficulties!) essentially new construction of the dynamical spacetime (DST) by pure quantum field means. Partly these efforts were already published but I would like to publish soon new more clear results.

Since I'm busy now I will read your article ASAP.

Sincerely yours,

Peter

Hi Professor Peter Leifer,

Very nicely said starting from… “Euclidian geometry, Riemann geometry, Maxwell electrodynamics to pseudo-Euclidian geometry of the spacetime and the relativistic generalization of the Newton's law of gravity lead to pseudo-Riemannian spacetime structure.” And the discussion of “what is the fundamental geometry in quantum physics?” wonderful...

Dear Mr. Gupta,

Thank you for very kind notes!

I agree with most of your ``No” like ``No singularities” but I think that attempt to reject

SR and GR is a crude mistake. I am sure that a new ``quantum geometry” should unavoidably contains the relativistic physics as a natural limit but nobody knows how to do it!

Best regards and wishes

Dear Dr. Leifer,

excellent essay. Our approach to the posed question of this contest are so different that I cannot even tell with certainty whether we would eventually agree. However, I find your conclusion very appropriate and agreeable. I will rate you high.

I hope you could find time to look through my essay

Best wishes,

Dear Mr. Flavio,

Thank you for very kind notes!

I think that K. Popper contribution in the modern philosophy is overestimated and it looks like a new religion of the scientific and quasi-scientific community.

Indeed, the famous principle of falsification is trivial. This principle being applied to the principle itself gives ``desirable” result – it is scientific since this may be falsified by an example of any physical (not mathematical!), biological or humanitarians doctrines - all these doctrines have limited area of the confirmation with experience and will be falsified early or later. The difference is hidden only in the area of their applicability and in the time of verification/falsification. Say, very silly statement may be disproved almost immediately, but smart theory like classical thermodynamics has a vast area of applicability up to now but in XX centaury the quantum theory was prolific for more deep understanding.

This principle is unpractical: nobody from scientists waiting for falsification of his prediction – this unavoidably will be more or less soon! (see the Einstein’s notes about the fate of physical theories). All our efforts are more or less perishable!

So, shortly speaking, all attempts in ``harassment of our consciousness” (Schrodinger) should be rejected! The main aim of the science is understanding. All different targets are secondary. As far as I understand you are young researcher. You have a time avoid the dangerous way of the formal following misty instructions.

Best regards and wishes

Peter

Peter,

Dynamical spacetime, geometry underlying the quantum. Exactly matches my idea of fundamental! High score.

I think you will find a lot to agree with in my essay, too.

Thanks for a great read.

Dear Mr. Terry Bollinger, thanks a lot for critical notes!

I accept your critics without any negative emotions. I know that what I would like to write as simple as possible almost never achievable. So, I may only to add some notes that probably will be helpful.

1. What I called Quantum Relativity (QR) is not some interpretation of QM. I assumed that QM is not fundamental and should be treated as some limit of more general quantum field theory (in my case over CP(N-1)).

2. Deformations of quantum states, I think it is a key element of the future theory. Some details may be found in the section 2.1 of my essay and in my articles.

3. I know that for most of readers of FQXi so detailed references are simply not needed. But may be for some readers it will be very useful. I would like to subscribe that reference on the nice article by Littlejohn and Reinsch [20] is absolutely needed for such kinds of readers since ``flexible quantum setup” in my theory akin to the gauge theory of classical deformable body nicely written in [20].

4. PDE’s mentioned above was already discussed in my articles [16,17,18]. Last time I found more logically simple construction of the DST and some modified equations come out. This matter will be published soon.

Sincerely your,

Peter

Hello Peter,

I like this essay very much and will vote so. In particular I like: "The main aim of the science is understanding. All different targets are secondary."

Also you commented: "I like the idea that there is some kind of geometric interpretation of quantum mechanics, and that through this interpretation some form of unification should be possible with the broader perspective of space time."

Do visit my essay "The Thing That is Space-Time". It postulates a different type of graviton and it fits with a traveling wave description.

Thanks for your essay,

Peter,

Glad I made it to your essay. It seems like me you've been focussed on quantum physics for a while. I found it a very nicely conceived and written article, and entirely agree; "QM is not fundamental and should be treated as some limit of more general quantum field theory.

Did you see my (top scored) 2015 Red/Green Sock Trick essay? That built on a compatible SR rationale which implied a Classical QM solution, which after 3yrs has clicked into place and is described in this years essay.

A full ontology is constructed, though not assuming 'singlet states' but from the different starting assumption of Maxwell's, and the Poincare Sphere's two momenta pairs in OAM. I hope you may get to it and comment. Measurement is considered as a momentum exchange mechanism with absorbing field electrons. Antiparalell (pair) polar axes and analysis of re-emission as a RELATIVE state ('same' or 'opposite') removes 'non-locality'.

Phase/hellicity of the 3 axis amplitudes.. Anyway, do read my essay, I'm sure you'll like it. A quick sequence intro in in my recent posts. Declan Traill's has the matching computer code and CHSH >2 plot with closed detection loophole.

Well done for yours, penciled in for a boost. Must talk more.

Best wishes

Dear Peter, thanks for your very kind letter.



I tried a few times to read you essays (2015,2017,2018) but I would like sincerely say that I cannot grasp your main idea and targets. Probably my poor English in non sufficient for your British (late Yuval Ne’enan wrote to me (1994) that my English is horrible). I think that it is the main obstacle for me. May I ask some simple questions in order to clarify your point of view?

1. What means the phrase ``compatible SR rationale which implied a Classical QM solution”?

2. What is you main target: to build modified QM or clarify QM at its status quo?

3. What means the phrase: ``full ontology is constructed, though not assuming 'singlet states' but from the different starting assumption of Maxwell's, and the Poincare Sphere's two momenta pairs in OAM”?

4. What is the difference between your `` full ontology” and, say, what we may read in QM textbook (Shiff, Dirac, etc.)?

Best regards,

Peter Leifer
