In Relativity: The Special and the General Theory, Einstein describes the theories that made him famous, illuminating his case with numerous examples and a smattering of math. This book is not a casual read, but for those who appreciate his work without diving into the arcana of theoretical physics, it will prove a stimulating read. ?The present book is intended,? Einstein wrote in 1916, ?as far as possible, to give an exact insight into the theory of relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.?
