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 …

The limitations set by the uncertainty principle on the measurement of the curvature of space
are determined by passing a small test particle around a geodesic triangle. In measuring the …

Although there are some changes in method and in some places in the notation in this
paper, which make it differ somewhat from the two papers I and II recently published in these …

It is shown how it is possible, by means of geometry and the introduction of a principle of
measurement, founded by analogy with the theory of H. Weyl, to discover a unity existing …

FIRST draft of this book was published in 1921 as a mathematical supplement to the French
Edition of Space, Time and Gravitation. During the ensuing eighteen months I have pursued …

In a previous communication it was pointed out that the problem of the quantum equations
could be regarded as having developed into a search for a modification of the Riemannian …

Since this report belongs to the session on general relativity, I thought it would be
appropriate to focus on those contributions to quantum gravity which have come from the" …

The articles collected in this volume were written for a Colloquium on Fifty Years of Quantum
Mechanics which was held at the University Louis Pasteur of Strasbourg on May 2-4, 1974 …

~ N THE present article we give an account of certain of the fundamental.. ideas and
assumptions underlying the general relativity theory and proceed to a discussion of various …

It is the purpose of the present paper to develop a form of the theory of relativity whIch shall
