Physics Frontiers
Randy and I have started up a companion podcast, Physics Frontiers, with shorter discussions of topics in physics. Check it out! Show notes at the Physics Frontiers website.
G4V: The Gravitational 4Vector Formulation of Gravity
Straight from PhysicsFMRandy Morrison and Jim Rantschler discuss topics in physics.
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 4vector form, with the usual gravitational potential in the temporal component).
Notes:
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.
