Geometry and Astronomy: Pre-Einstein Speculations of Non-Euclidean Space
by Helge Kragh
Publisher: arXiv 2012
Number of pages: 76
The recognition that physical space (or space-time) is curved is a product of the general theory of relativity, such as dramatically shown by the 1919 solar eclipse measurements. However, the mathematical possibility of non-Euclidean geometries was recognized by Gauss more than a century earlier, and during the nineteenth century mathematicians developed the pioneering ideas of Gauss, Lobachevsky, Bolyai and Riemann into an elaborate branch of generalized geometry.

The Radiation Laboratory in Berkeley, California, was the birthplace of particle accelerators, radioisotopes, and modern big science. This volume is a saga of physics and finance in the Great Depression, when a new kind of science was born.

This volume represents an effort in the direction of the biographical history of electricity. The controlling idea in its preparation was to provide brief yet reasonably complete sketches of the lives of the great pioneer workers in electricity.
Contents: Multiverse; Many-worlds interpretation; Novikov self-consistency principle; Wormhole; Faster-than-light; Chronology protection conjecture; Philosophy of space and time; Eternalism; Determinism; Free will; Time travel in fiction; etc.
