What is the measurement being performed?. https://en.wikipedia.org/wiki/Geiger_counter First line uses word measure. So is not the Geiger counter (who's radioactive decay detection event triggers the detonator) counted as an observer? Sorry, it seems like a bunch of nonsense to me. I guess I am not...

Must remember to double proof read before logging out! Here is a slightly reworded version of above post: Suppose there is, instead of a cat inside Schrodinger's box notionally perfectly shielding contents from external environment, a high explosive charge. Instead of a radioactive source triggerin...

That is the title of a recent short essay by David Mermin in the latest Physics Today magazine. https://physicstoday.scitation.org/doi/full/10.1063/PT.3.5027 I agree with him about that. I posted the following on Gill's Google group with the subject line, "LOL! Some day you guys will figure it ...

Well, here is a doozy for you! The correlations works for 2 particles with 7D vectors!




I guess this is just regular 7-spheres.
.

I was able to simplify the 7-sphere 2 particle version a bit. https://sciphysicsfoundations.com/sims/7-sphere2P3.png https://sciphysicsfoundations.com/sims/7-sphere2P4.png At the end you can see a typical interaction between detector A and particle spin, Ls1. We have a scalar, 6 bivectors, and a pse...

Here is the 7-Sphere 2 particle version with no hidden variable. https://sciphysicsfoundations.com/sims/7-sphere2P1.png https://sciphysicsfoundations.com/sims/7-sphere2P2.png Now there are 5 different local models with no hidden variables that give the quantum mechanical predictions! The Bell fanati...

I think it is OK to have just one of the spin vectors reversing the product order since they are all linked together.


.

Yes, it works 3D2D with the spin vectors 3D and detectors 2D. I took out the cross correlations to concentrate on the main correlation. https://sciphysicsfoundations.com/sims/7-sphere1.png https://sciphysicsfoundations.com/sims/7-sphere2.png https://sciphysicsfoundations.com/sims/7-sphere3.png And w...

Here are the files for the 7-sphere simulation no hidden variables. Large files. https://sciphysicsfoundations.com/sims/joyGA_7-sphere4Pabcd-noHV.pdf https://sciphysicsfoundations.com/sims/joyGA_7-sphere4Pabcd-noHV.nb I'm using the "y" component of the singlet spin vectors to toggle the or...

. Looks fine to me. Feel free to update the Mathematica Notebook archive if the link or DOI is not changed by updating. Yes, "rooted in 3-sphere topology" is more accurate than "rooted in geometric algebra." GA is just a convenient tool. Actually to be more correct, all quantum ...

Just came across these linked articles of respectively May and April this year https://www.eurekalert.org/news-releases/952396 https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.4.023075 (open access) The novelty as explained at end of abstract there is '...the recently introduced...

I did some improvements to the Notebook Archive file. I got rid of the Qcoordinates thing and put in the limits on the A and B functions. If it looks OK, I will try to update the Mathematica Notebook Archive. https://sciphysicsfoundations.com/sims/joy_archive1.png https://sciphysicsfoundations.com/s...

. This paper is now on the arXiv: https://doi.org/10.48550/arXiv.2205.11372. In it, I review the past 15 years of my work, spelling out local, realistic, and deterministic foundations of quantum correlations, without resorting to superdeterminism, retrocausality, or any other conspiracy loophole. T...

Here is the same thing but using the Quaternion Package that is built into Mathematica. It is faster than using the Clifford package. Note that I got rid of the silly "Qcoordinates" thing John Reed had devised. Conversion to quaternions is done more correctly now. https://sciphysicsfoundat...

The new reverse order scenario works for the local QM prediction simulation also. https://sciphysicsfoundations.com/sims/qm-local7.png https://sciphysicsfoundations.com/sims/qm-local8.png https://sciphysicsfoundations.com/sims/qm-local9.png Still no hidden variable! Yep, Bell's junk physics theory i...

Here is an alternative simple GA simulation. I realized last night that we don't really know if particle 1 goes to A or B. Likewise for particle 2 so, I have switched the spin representation in the reverse order to show that it doesn't matter. And this simulation is using the direction of the "...

Joy, you define your measurement outcomes in (13) and (19). This involves limits: limits as s _1 converges to mu_1 a , and as s _2 converges to mu_2 b . But mu_1 and mu_2 are not fixed, in fact they are defined in terms of s _1 and s _2, see (11): mu_1 = sign( a . s _1) and mu_2 = sign( s _2 . b ) ...

This also works with Ls1_k_4 > 0 which is the "z" component of the singlet spin vector. I think I will be using that. IOW, the left or right handedness of the product is randomly determined by the orientation of the singlet vector instead of independently by lambda = +/-1. Let's say that t...
