Randy talks to Jim about gravitoelectromagnetism. Based on the similarity between Newtonian gravity and electrostatics, there should be a second gravitational field,the gravitomagnetic field. What are the implications of the existence of such a field, and how large are those effects?
Jim talks to Randy about the pilot wave interpretation of quantum mechanics, which separates the particle and wave behavior of a non-relativistic quantum particle into that of a particle moving in and exciting a quantum mechanical medium.
Randy talks to Jim about Carver Mead's G4V, a formulation of gravitation combining the equivalence of inertial and gravitational mass with a vector potential formulation of gravitation (a 4-vector form, with the usual gravitational potential in the temporal component).
Carver Mead's Lecture that we discuss in this episode.
Carver Mead's book Collective Electrodynamics: Quantum Foundations of Electromagnetism, which is an interesting argument for the fundamentality of the vector potential in electrodynamics.
Clifford Will's Theory and Experiment in Gravitational Physics, which discusses the theories of gravitation still considered viable at the time of its publication and the ways in which they are tested. This book is also referenced in the discussion.
