Summary

Nicolas Gisin (University of Geneva) argues time is NOT an illusion while defending quantum free will They discuss quantum chance, superdeterminism, and Gisin’s views on quantum gravity and the logical foundations of physics.0:00 Introduction3:38 Gisin's "Quantum Chance" book is a friendly introduction to QM6:36 Consciousness is outside today's physics and may always be7:48 Indeterminacy is necessary but not sufficient for free will9:37 Free will is necessary for "rationality" to exist10:40 Free will comes FIRST in the "logical order"21:39 What does mathematics have to say about free will and consciousness?27:18 Intuitionism vs Constructionism28:22 Classical physics is NOT deterministic34:27 Does he agree with Stephen Wolfram that it's computation underlying physics?36:06 Time is "thick" like molasses40:21 Intuitionist mathematics and law of excluded middle42:57 Graham Priest's paraconsistent logic and other forms of logic49:32 A new understanding of time is needed for Quantum Gravity52:55 Discrete spacetime?

0:00.0	This is a desultory interview in keeping with the theme of the indeterminate and unfolding nature of time.
0:06.0	For those who were intrigued by Lou Alessando's comments on the blurred notion of the present,
0:11.0	i.e. his metaphor of the cigarette that burns unevenly, Nicholas Jisson's concept of thick time is the closest I've heard to a rigorous account of it.
0:20.0	Nicholas Jissen is a professor at the University of Geneva working on the foundations of quantum mechanics and quantum information,
0:27.6	both experimentally and theoretically.
0:29.6	In this episode, we talk about the existence of free will, the indeterminacy of reality, and the unreality of the real numbers. Nicholas is one of the world-renowned
0:39.4	experts in quantum theory, and we're extremely grateful that his first podcast appearance is on the
0:45.1	Theories of Everything channel. Thank you, Professor. Click on the timestamp in the description
0:49.2	if you'd like to skip this intro. My name is Kurtzai Mungle. I'm a Torontoian filmmaker,
0:54.0	with a background in
0:55.3	mathematical physics dedicated to the explication of the variegated terrain of theories of everything.
1:01.1	From a theoretical physics perspective, but as well as analyzing consciousness and seeing
1:06.1	its potential connection to fundamental reality, whatever that is. Essentially, this channel
1:10.7	is dedicated to exploring the undarived nature of reality, whatever that is. Essentially, this channel is dedicated to exploring
1:12.0	the undarived nature of reality, the constitutional laws that govern it, provided those laws
1:17.0	exist at all, and are even knowable to us. If you enjoy witnessing and engaging with others on the
1:21.7	topics of psychology, consciousness, physics, etc., the channel's themes, then do consider
1:27.1	going to the Discord and the
1:28.3	subreddit, which are linked in the description. There's also a link to the Patreon. That is
1:32.7	patreon.com slash Kurchai Mungle. If you'd like to support this podcast, as the patrons and the sponsors
1:38.5	are the only reasons that I'm able to have podcasts of this quality and this depth, given that I can
1:43.9	do this now full-time
