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.

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.
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 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.
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.
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.
