The passage from the classical to the quantum mechanics is characterized by the
introduction of the Pl~ nck constant, which Mlows to measure linear momenta in units cm-1 …

First we define the terms velocity, energy, etc.(for example, for an electron) which remain
valid in quantum mechanics. It is shown that canonically conjugate quantities can be …

Gravitation is pictured as ((force, fiat space)> or as (~ no force, curved space~>. Should
quantum mechanics be presented as geometry of a suitable space, analogical reasoning …

In Einstein's theory of gravitation it is assumed that the geometry of space-time is
characterised by the following equation for the measurement of displacement:—ds 2= gmn …

We propose to attempt, in this note and others to follow, an approach to the program
advocated by W~ EL~ R in his (~ Frontiers of Time,) and other papers (1). We shall begin by …

The task of creating a quantum theory of gravity is compared with Einstein's creation of a
relativistic theory of gravity. The philosophical and physical foundations of this theory are …

This monograph is a sequel to my earlier work, General Relativity and Matter [1], which will
be referred to henceforth as GRM. The monograph, GRM, focuses on the full set of …

First we analyse the space-time structure of classical mechanics and quantum mechanics in
the framework of projective geometry. Dimensions are defined group-theoretically, and it is …

Classical gravitation, electromagnetism, charge, and mass are described in a preceding
article in terms of curved empty space and nothing more. In advance of the detailed …
