The Machine in the Ghost
24:18This 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
PhysicsFM - Intermission - Quantum Metaphysics
1:28:17Jim 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 8 - Measurement and Compensation
42:15Jim 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.
PhysicsFM - Quantum Paradoxes 7 - Quantum Measurements - Jim Rantschler and Randy Morrison
36:23Randy and Jim talk about measurements of quantum systems, specifically in terms of a paradox involving the measurement of the velocity. This includes a long discussion of the von Neumann model of quantum mechanics.
