Relativity: The Special and General Theory

Albert EinsteinÂ's classic guide to the theory of relativity—with insights from todayÂ's leading experts

This new edition of Relativity—the first updated version in over fifty years—includes a wealth of original material written by some of todayÂ's foremost scientific authorities. Bestselling author and physicist Roger Penrose puts EinsteinÂ's work in historical context and details major developments in relativity theory over subsequent years. Relativity expert Robert Geroch provides commentary on key aspects of the special and general theories; and historian David Cassidy explores the profound impact of EinsteinÂ's ideas on our culture at large. Now, over ninety years after its first publication, this definitive edition brings a classic text into the new millennium. BACKCOVER: “The additions to the original text give considerable insight and are a valuable addition, particularly for anyone approaching the subject for the first time.”
—Choice

“ItÂ's as though you are sitting in his classroom, watching [Einstein] alternate between gesticulating and chalking equations onto the blackboard.”
—The Washington Post Book World
