Booked! Author The Clockwork Rocket - Greg Egan

"It was only in 1996 that I finally came across Gravitation by Charles Misner, Kip Thorne and John Wheeler. Published in 1973, this 1279-page masterpiece takes all the time it needs to prepare the reader for the subject, spelling out the beautiful geometric principles that underly Einstein’s conception of gravity. In general relativity, the way lengths and angles are measured varies from place to place and time to time, so there needs to be an underlying framework in which these concepts can be defined without simply taking them for granted. That framework is known as differential geometry, and once you learn its concepts and tools, black holes, the expanding universe, and other counterintuitive features of modern science finally become comprehensible. This book gives you the mathematics you need, defined with care, but backs it all the way with physical intuition. I only wish I’d read it twenty years earlier."
