Maxwellian Ratchets with Alex Jurgens
Jim talks with Alex Jurgens about Maxwellian ratchets, automata that are similar to Maxwell's Demon. They talk about their implications for information processing and entropy.http://frontiers.physicsfm.com/77

Undeciability and Theories of Everything with Claus Kiefer

Categorical Probability and the Measurement Problem
Jim talks with Nick Ormrod and V. Vilasini about their use of categorical probability theory to analyze the measurement problem. We discuss categorical probability theory, which allows them to abstract from particular mathematical formulations of quantum mechanics to more general ideas about states and measurements and observers than found in Hilbert space formulations. They use this to look at the various properties of quantum mechanics and how they relate to each other, in particular how relativity affects the measurement problem.Show Notes: http://frontiers.physicsfm.com/75

Stochastic Thermodynamics with David Wolpert
Jim talks with David Wolpert about the non-equilibrium behavior of computation, what it means for entropy, and how it relates to traditional thermodynamics.Show Notes: http://frontiers.physicsfm.com/74

Quantum Money with Jiahui Liu
Jim discusses quantum money with Jiahui Liu. Quantum money is a linchpin of quantum cryptography. The ability to create secure banknotes using quantum computers would allow even more secure methods of encryption for communications.

Born Rule and Gravity with Antony Valentini
Jim talks with Antony Valentini about the difficulties of interpretation of quantum mechanics in light of quantum gravity. In particular, Antony discusses the failure of the Born Rule due to the impossibility of normalization (the fact that probabilities must sum to 100%) at that scale, and therefore the need to interpret the wavefunction as something more than merely the knowledge of the observer about the system. They spend some time talking about the de Broglie-Bohm interpretation in light of quantum gravity.Show Notes: http://frontiers.physicsfm.com/72
Customer Reviews
Insightful and informative.
I absolutely enjoy all the insights and perspectives on this podcast I just wish the Ecco wasn’t so dominant on the recording of episode 71. With that said, I enjoy very much this podcast. Thank you. Look forward to see your growth.
The best!
This is *the* physics podcast. It deserves a much wider following.
Excellent Podcast
Very good breakdown of information. Really loved the chemistry between Jim and Randy. RIP Randy! Now you are back with the Universe!
