The Meaning of Relativity
by Albert Einstein
Publisher: Princeton University Press 1922
Number of pages: 134
A condensed unified presentation intended for one who has already gone through a standard text and digested the mechanics of tensor theory and the physical basis of relativity. Einstein's little book then serves as an excellent tying-together of loose ends and as a broad survey of the subject.

We may consider Geometry as a first attempt at a study of the outside world. It may be considered as a system which reflects our experiences with features of the outside world, namely features connected with the displacements of rigid bodies.

This little book gives a remarkably readable and intelligible account of the theory of relativity. The author is presenting his material without presupposing more than elementary algebra and the elements of plane geometry.

This is a textbook on theories of special and general relativity. It is assumed that the reader has an understanding of mathematics through calculus and partial differential equations. The relevant tensor calculus is presented throughout as needed.
This book examines the evolution of the principle of relativity in its classical, special, and general incarnations, with the aim of showing how it has repeatedly inspired advances in our understanding of the physical world.
