"[A] wonderful book that combines a facsimile of Einstein's original manuscript, an English translation and a rich annotation."---Bill Condie, Cosmos Magazine --- "Gutfreund and Renn dissect every page of the manuscript, explaining the meaning of each passage and describing Einstein's thought processes leading up to it. . . . The Road to Relativity is accessible and engaging."---Tom Siegfried, Science News --- "The Road to Relativity by Hanoch Gutfreund and Jürgen Renn reproduces the 45 handwritten--and hand-corrected--pages of Einstein's general theory, accompanied by extensive annotations on the science, its historical context and the implications for the future. The volume also includes a glossary of scientists and philosophers relevant to Einstein's work and some entertainingly lively illustrations--such as one of Einstein pouring coffee on a moving train to demonstrate that motion is relative--by Laurent Taudin."---Nancy Szokan, Washington Post --- "[Gutfreund and Renn] remind us of the charm a manuscript affords: rare glimpses into the working process of a great mind." --- "Any devotee of Einstein will relish the chance to parse this annotated facsimile of the physicist's original manuscript on general relativity. . . . [Gutfreund and Renn's] cogent descriptions and the accompanying illustrations and documents open a fascinating window onto Einstein's otherwise inaccessible opus."
