Description:Widely considered the greatest contribution to the philosophy of science, Einstein’s theory of relativity has often been viewed as comprehensible only to highly trained scientists. This book, however, contains the great physicist’s own explanation of both the special and the general theories, written for readers interested in the theory but not conversant with the mathematical apparatus of theoretical physics. Presenting the ideas in their simplest, most intelligible form, this three-part volume outlines the special theory, the general theory, and in a final part, offers considerations on the universe as whole.
