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.

PhysicsFM - Intermission - Quantum Metaphysics
4/3/2017
1:28:17
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
5/8/2015
1:05:41
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
2/7/2015
42:16
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.
PhysicsFM - Quantum Paradoxes 7 - Quantum Measurements - Jim Rantschler and Randy Morrison
22/4/2015
36:23
Randy 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.
PhysicsFM - Quantum Paradoxes 6 - Nonlocality and Causality - Randy Morrison and Jim Rantschler
25/3/2015
52:09
Jim and Randy discuss Aharonov and Rohrlich's suggestion that quantum mechanics should be formulated in terms of axioms based upon its physical peculiarities -- Nonlocality and Causality.
