The Einstein Theory of Relativity

Theory of Relativity from the perspective of a scientist contemporary of Einstein's. It is easy to read, and is intended for an audience who has only basic scientific knowledge. It doesn't cover the theory in great detail; the goal is to help people understand the basic meaning of the theory and how it was validated by experiment. Since it was written 90 years ago, some of the science in the book has changed (ie. the cosmic aether) which adds a quaint feeling to the book.
