Summary

Jacob Barandes challenges a hidden assumption in quantum theory, linking classical probability to quantum mechanics through a so‑called mathematical accident. The episode explores how this view reshapes Bell’s theorem, the measurement problem, and offers a realist path forward for quantum physics.0:00 Introduction1:02 Non-locality & Local Realism13:58 Quantum Theory20:45 Copenhagen Interpretation28:11 Many Worlds Interpretation34:54 Creating Indivisible Stochastic Process50:59 Indivisible Stochastic Process1:01:46 Teaching Black Holes to Graduate Students1:04:59 Coordinate Systems in Space-Time1:06:58 Teaching Black Hole Coordinates1:10:11 Insights from Nima1:13:41 Nima's Course on Quantum Mechanics1:16:22 Quantum Foundations and Cosmology1:18:48 Transitioning to Quantum Gravity1:23:10 Philosophy's Role in Physics1:26:10 Leaving String Theory1:33:39 Interpretations of Quantum Mechanics1:37:02 Challenges of String Theory1:42:49 Quantum Field Theory Insights1:50:30 Foundations of Quantum Field Theory1:53:47 Particle Existence Between Measurements1:59:44 Speculations on Quantum Gravity2:01:41 Legacy and ContributionsSPONSORS:- I personally subscribe to The Economist.

0:00.0	I don't think it's coherent. I don't think that answers the questions of what's going on in quantum foundations.
0:06.6	Harvard's Jacob Barndes exposes the hidden assumption that has blinded us for nearly a century.
0:13.4	One day, while preparing to teach quantum mechanics, Jacob made a startling discovery.
0:18.4	Quantum theory and classical probability are separated by a single
0:22.7	unnoticed presumption, Markovianity. Drop it and the gap between them vanishes entirely.
0:30.2	Even more startling, this mathematical accident bypasses the so-called local realism constraint
0:36.9	of Bell's theorem and dissolves the measurement
0:39.9	problem. All without magic. This discussion ranges from black holes that rain to the mathematical
0:46.9	beauty of indivisible processes, culminating in a meditation on legacy, kindness, and why the next
0:53.8	revolution in physics demands philosophers
0:56.5	and physicists working as one.
1:01.0	Jacob, welcome back.
1:03.7	It's always a pleasure to talk with you, Kurt.
1:05.8	It's always a pleasure to have you, to host you. Thank you so much.
1:08.9	Lovely being here in Toronto. It's a lovely city.
1:11.3	And if you haven't been to Toronto, you should come visit. It's great.
1:14.6	Is Toronto real? Here, how about that? Is Toronto
1:17.6	non-locally real or locally real? Firstly, let's focus on this term real.
1:24.3	Has the 2022 Nobel Prize disproved so-called local realism?
1:30.4	If you read the press release from the 2022 Nobel Prize in Physics that was given to
1:37.4	Ossespe, Klauser, and Zylinger for their work testing experimentally violations of a generalized set of
1:48.6	equalities that began with the Bell inequality and evolved into things like the CHSH
