"The style is very clear and concise, and the treatment is authoritative throughout." — ChoiceRelativity remains a topic of crucial interest for scientists grappling with its implications for physics, astronomy, cosmology, and other disciplines. Laymen, too, are fascinated by relativity theory, which overturned the classical order of Newtonian physics and postulated ideas about space and time that often seem to contradict common sense.The present work is a very clear, concise, and authoritative exposition of both the special and general theories of relativity. Intended for nonscientific readers with a knowledge of high school math, the book offers illuminating coverage of such topics as the speed of light, simultaneity, time distortion of space and mass, journeys to the stars, dimension and hyperspace, the theory of general relativity, anomalies in space, and the structure and evolution of the universe.Readers with an inquisitive bent for cosmic affairs will enjoy this mind-stretching journey into the mysteries and majesty of the physical universe, where they'll share the author's explanations and speculations about why the speed of light is the speed of time, whether it may be possible to travel backward in time, how black holes are formed, how it is possible that space is curved, and much more. For anyone curious about the nature of the universe and how relativity theory continues to help scientists unlock its secrets, this accessible popular treatment is an invaluable companion and guide. - from Amzon
