Analogy between electrodynamics and gravitation
Abstract
A derivation of field equations of general relativity is given, proceeding from direct physical motivations, among which an outstanding role is played by the analogy between electrodynamics and gravitation. In this way, a scalar field, coupled to the same gravitational sources and having an arbitrary weight, is inserted as well.
