Physics Biggest Quantum Heretic | Jonathan Oppenheim

Welcome to Theories of Everything's "Rethinking the Foundations of the Physics: What is Unification?" series featuring Jonathan Oppenheim. Jonathan Oppenheim is a renowned theoretical physicist and professor at University College London (UCL), known for his groundbreaking research in quantum information theory, quantum gravity, and the relationship between quantum mechanics and thermodynamics. Jonathan holds a Ph.D. from the University of Cambridge and is recognized for his contributions to the fields of quantum foundations and quantum computation. https://www.ucl.ac.uk/oppenheim/ SPONSOR (The Economist): As a listener of TOE, you can now enjoy full digital access to The Economist.

Om Podcasten

Exploring theoretical physics, consciousness, Ai, and God in a technically rigorous manner. If you'd like to support this endeavor, then please visit the Patreon ( https://patreon.com/curtjaimungal ). Thank you for your charitable and kindhearted support. My name's Curt Jaimungal, a Torontonian with a degree in mathematical physics from the University of Toronto and I analyze various Theories of Everything from this analytic perspective, though more and more opening up to alternative approaches. The separating factor of TOE from other podcasts is its focus on depth even at the risk of limiting the audience due to how much detail we delve into subjects. Paralleling the intensity found in academic discourse, we're increasingly embracing a spectrum of unconventional ideas to conduct research during this podcast, rather than merely conveying existing information.
