Professor Gerard 't Hooft - Determinism all the way
We apologise that the audio quality was poor due to some instrument issues at the beginning of the video. The audio becomes clear from 0:24:30.
Title: Determinism all the way
—
Abstract:
Usually quantum mechanics is said to require an entirely nonclassical way of thinking about what it is that the theory describes. Bell's theorem and the CHSH inequalities seem to imply that there is no ontological or local description of fields or particles that can reproduce its equations, unless one assumes an absurd sort of conspiracy or "superdeterminism". I will show that this is not exactly true. If one boldly assumes that all physical equations are as classical as Newton's equations or those of Maxwell, and, in addition, while furthermore the variables are discrete, then one can reproduce exactly the probability distributions predicted by the Schrödinger equation. Non-commutativity is caused by hidden variables that move too fast to be precisely recorded.
This leaves us to explain why quantum mechanics generates so many apparent paradoxes. One must assume "Determinism all the way", and: "the conservation of ontology."

About the speaker: Professor Gerard 't Hooft is a Dutch theoretical physicist and professor at Utrecht University, the Netherlands. His research focusses on gauge theory, black holes, quantum gravity and fundamental aspects of quantum mechanics. His contributions to these fields include a proof that Yang-Mills non-Abelian gauge field theories are renormalizable, dimensional regularization and the holographic principle. He shared the 1999 Nobel Prize in Physics with his thesis advisor Martinus J. G. Veltman "for elucidating the quantum structure of electroweak interactions".
