The fundamental equation of wave mechanics and the metrics of space

Abstract

The relativity theory of Weyl and Eddington is an extension of what may be described as the geometric principle of relativity to the metrics of space. This extension permits the inclusion of electromagnetic phenomena into a system of geometry and metrics so that we have a consistent and fundamental scheme for the description of gravitational and electromagnetic phenomena. Recently considerable light has been thrown on the relation between classical and quantum theory by the work of de Broglie, Schroedinger and others.
