The Machine in the Ghost

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. Show Notes: http://papers.physicsfm.com/3

The Quantum Bookie

I talk about Quantum Bayesianism, the extension of the Bayesian interpretation of probability to quantum mechanics, through the work of Christopher Fuchs. Show Notes: http://papers.physicsfm.com/1

PhysicsFM - Intermission - Quantum Metaphysics

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.

PhysicsFM - Quantum Paradoxes 9 - Quantum Cats

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?

PhysicsFM - Quantum Paradoxes 8 - Measurement and Compensation

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.
