Sidelights on Relativity (Illustrated Edition)

Two unabridged addresses summarizing aspects of Einstein's Special and General Theories of Relativity comprise this succinct volume. The first, Ether and Relativity, was delivered in 1920 and examines the properties demanded of the ether of space by the theory of relativity. Geometry and Experience, delivered the following year, describes the limits within which the Euclidean system can be held to be approximately true in relation to the concept of a finite universe. Written clearly and concisely, these lectures are a fascinating read for both scientist and layman. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Sidelights on Relativity

Excerpt from Sidelights on Relativity How does it come about that alongside of the idea of ponderable matter, which is derived by abstraction from everyday life, the physicists set the idea of existence of another kind of matter, the ether? The explanation is probably to be sought in those phenomena which have given rise to the theory of action at a distance, and in the properties of light which have led to the undulatory theory. Let us devote a little while to the consideration of these two subjects. Outside of physics we know nothing of action at a distance.
