Jim goes on a diatribe about infinities and the multiverse.
-
In this episode, I discuss a paper talking about the relationship between physical entropy and information-theoretic entropy in the context of quantum communication.

This week, I talk about the fate of the universe in Bohmian Cosmology. Specifically, how Torres, Fabris, and Piattella use the de Broglie-Bohm interpretation of quantum mechanics to modify the Wheeler-De Witt equation in the an accelerating universe.

I talk about a paper by John Archibald Wheeler, "Information, Physics, Quantum: The Search for Links."

I talk about Quantum Bayesianism, the extension of the Bayesian interpretation of probability to quantum mechanics, through the work of Christopher Fuchs.

Jim and Randy discuss the ways in which we interpret the wavefunction, quantum indeterminancy, and other strange things that happen in quantum mechanics -- going through nine classes of interpretation and what they mean about the underlying reasons for quantum mechanical behavior.
-
Randy and Jim discuss the implications of Schroedinger's Cat. In light of the measurement problem, in light of the collapse of the wave function, how can you understand what is happening to a quantum mechanical system?
-
Jim and Randy discuss how "compensation forces" allow measurements of non-canonical variables without the difficulties discovered in the previous episode. They also discuss why some very important concepts of classical physics -- velocity and the electric field -- are not canonical.
-
Randy and Jim discuss modular variables and how looking at an infinite number of slits in a diffraction grating can better elucidate the process of quantum interference than the two-slit experiment.
-
Jim and Randy talk about two paradoxes that help describe the Aharonov-Bohm effect. This requires an excursion into the gauge invariance of the vector potential of electrodynamics -- and how that gauge has real effects in quantum theory, even though it did not in classical physics.
