Further opportunities to interact

[gill1109]

I'm so glad that Fred has managed to keep this forum going. I just wanted to mention two other opportunities for interactions:

QM foundations & nature of time seminar
"relaxed discussions about the foundations of physics"
Every other Thursday 17:00-19:00 Central Europe Time
Organiser: Jarek Duda, Krakow, Poland
http://th.if.uj.edu.pl/~dudaj/QMFNoT
Two weeks from now, the speaker will be Marian Kupcszynski (Quebec), author of many papers supporting local realism, on account of contextuality. The talks take up to one hour, discussion usually lasts at least another hour. Platform: Zoom.

Bell inequalities and quantum foundations
Founded (and "owned") by Alexandre de Castro. It has two "managers" - Alexandre and myself. We (the managers) "manage" as little as possible. Recently there was very little traffic. Some new members with new ideas would be welcome.
https://groups.google.com/g/bell_quantum_foundations

Undoubtedly there are many more such venues!

In general, there is no point contributing on a forum that is hidden from the public. It's fine to require authentication to participate but it makes no sense to hide the content from the public like the latter.

Yep, it is definitely pretty silly to have a private forum of some kind unless you are going to attack the US Capitol Building or something worse.

Well.......... For the Bell fanatics there is a lot they would like to keep hidden from the public.

I will ask the owner/founder what they think about making it public. And the members. Thanks for the suggestion.

Many of the forum members are Bell opponents. Possibly the majority!

Good. It is really ridiculous to have it private unless you can't figure out a way to block spammers. I know that Google is not very good at that.

Jarek Duda posted this to several groups:

We are reactivating the QM Foundations and Nature of Time seminar - focused on discussion, hoping to have talks every two weeks Thursdays or Fridays at 17 Warsaw time (CEST).
Please contact us if wanting to give a talk, or maybe having some organizational suggestions.
The current link and list of talks are in the webpage: http://th.if.uj.edu.pl/~dudaj/QMFNoT also https://researchseminars.org/seminar/QMFNoT

This Thursday 25 November at 17:00 CEST/Warsaw time we have talk:

Speaker: Marian Kupczyński (UQO)

Title: Quantum nonlocality: how does nature do it?

Abstract: Local realistic and stochastic hidden variable models define experimental protocols, which are inconsistent with experimental protocols used in real Bell Tests. Therefore, it is not surprising that they fail to describe correctly the experimental data. In 2009 Nicholas Gisin claimed in Science, that quantum correlations come from outside the space-time due to the quantum magic. Since we do not believe in magic, we propose a locally causal explanation of these correlations. Neither super-determinism nor retro- causality is needed, nor is experimenter’s freedom of choice (EFO) compromised. In our contextual model, setting dependent variables describing measuring instruments are correctly introduced. Outcomes are predetermined both by instrument variables and variables describing incoming correlated signals at the moment of the measurement. There does not exist a joint probability distribution of variables describing all the possible settings, thus Bell inequalities may not be derived. In this talk, based on the articles listed below, we also explain in detail why the assumption called free choice-no conspiracy-measurement independence has nothing to do with EFO and should be rather called noncontextuality assumption. The violation of Bell inequalities neither implies the nonlocality of Nature nor the violation of EFO. It only confirms the contextuality of some observables in quantum domain and that outcomes are not predetermined before the experiment is done.

@gill1109 Looks like a very good waste of time. But thanks for posting anyways.

You might get more traffic there, if you stopped posting so much nonsense on that Google group.

And still no Bell Fanatics from there came over here and posted as guests even. The cowards don't really believe in what they are spewing is all I can figure.

Jarek Duda’s Krakow seminar:

current link and list of talks are in the webpage: http://th.if.uj.edu.pl/~dudaj/QMFNoT also https://researchseminars.org/seminar/QMFNoT

This Thursday 9 December at 17:00 CEST/Warsaw time we have talk:

Speaker: Valeriy Sbitnev (Berkeley)

Title: Quaternion algebra on 4D superfluid quantum space-time. Gravitomagnetic equations and something else

Abstract: Gravitomagnetic equations result from applying quaternionic differential operators to the energy–momentum tensor. These equations are similar to the Maxwell’s EM equations. Both sets of the equations are isomorphic after changing orientation of either the gravitomagnetic orbital force or the magnetic induction. The gravitomagnetic equations turn out to be parent equations generating the following set of equations: (a) the vorticity equation giving solutions of vortices with nonzero vortex cores and with infinite lifetime; (b) the Hamilton–Jacobi equation loaded by the quantum potential. This equation in pair with the continuity equation leads to getting the Schrödinger equation describing a state of the superfluid quantum medium (a modern version of the old ether); (c) gravitomagnetic wave equations loaded by forces acting on the outer space. These waves obey to the Planck’s law of radiation.

"Quaternions are a natural framework of 4D space-time, where the unit element relates to time, and three others relate to 3D space."
Not quite right! As I said in another thread, quaternions are representations of rotation or spin. I suspect these people are not on a good path.

It's just one person: Valeriy Sbitnev. You may be right.

Meantime, you have had some responses to your posts in the Google Group. I don't know if you are still following emails from the group.

No thanks. Google groups are really lame. Plus there is way too much nonsense from morons and idiots over there. The Bell fanatics over there are afraid to come to this forum to strut their wrong stuff. Cowards!
