Maudlin is in a class of his own - for elucidation.

The issue with superdeterminism is that it can never be experimentally verified (by definition). Therefore it is viewed by many (myself included) as a more of a “cop out” than a legitimate scientific theory.

got to love the clarity and step by step explanation of maudlins lecturing. important ideas!

Really good

Can't recommend highly enough

He should have called his paper _For Whom The Bell Tolls_

The problem here is too many words not enough equations. Talk about the equations not what other ppl say about equations you're not currently looking at. The primary issue here is that when talking about equations the ALL of the details are very important.

Any computer simulation of quantum mechanics needs to make use of a random number generator (stating the obvious?) but modification of the Schroedinger equation is prohibited, whether the modification be explicit or implicit. Does this bring our enquiries to a quick end? No, because there is a nonlocal degree of freedom to be exploited, as hinted at by Bell's Theorem. I propose tachyonic Brownian motion which is orthogonal to the Schroedinger equation, which is an oscillation in the other way to travel faster than light. I am sure that there are other ideas. Please let's hear them. Surely somebody like me, an amateur, doesn't have this subject all to himself !

I’m an amateur now, but I did a PhD on the computer simulation of the Navier-Stokes equations using Alexandre Chorin’s model of vorticity in Brownian motion. This requires a random number generator and it is pretty obvious to ask questions about doing something similar for quantum mechanics. One difference is that there is no viscosity term that can be added to the Schroedinger equation. We need to think of something new.

Good - check out slides available at website referenced in conference website above.

this is an excellent talk. best short explanation of Bell and to the actual problems concerning causality and locality confronting quantum theory. talks like this make me think more bachelors degrees should simply be replaced with philosophy/history of science.

love for Maudlin.
Because he pushed the Hammer on the nail.
However the world seems non local entangled as a system, if we live in one of the dual CPT symmetric copy multiverses, which are full symmetric. Called the 12x Raspberry multiverse of Q.FFF theory. Non local EPR RELATED.

I feel so non-local when I listen to Bell clarifications.. I find I get some great non local effects in my photography when I use three polarizing filters. Why are quantum physicists such horrible photographers? You need to know how to manipulate the photons or you will wash out as a photographer.

Maudlin knocks the heads of physics theorists together!

24:41 - So what the paper argues is that if you have events A and B, A cannot be thought of as disturbing or influencing B if B is outside of A's future light cone.

There is a way around Bell's theorem, and it's superdeterminism. If one assumes that experimentalists are not free to choose the measurement they make, Bell's inequalities don't apply anymore.
