GRAVITY

Galileo, the first to examine closely the process of free and restricted fall, Newton, originator of a universal force, and Einstein, who proposed that gravity is no more than the curvature of the four-dimensional space-time continuum. Most of the book is focused on Newton s ideas, with a concluding chapter on post-Einsteinian speculations concerning the relationship between gravity and other physical phenomena. This remarkably reader-friendly volume is graced with the author s own drawings, both technical and fanciful.
