Relatively Speaking

The discovery of relativity is one of the major accomplishments of the physical sciences, and also one of the least understood. In this book the author introduces non-scientists to relativity as well as some of its applications in cosmology and the study of black holes.

This book is based upon a series of lectures delivered during the past decade to nontechnical audiences at Harvard University. As in the lectures, Eric Chaisson aims here to share the fundamentals of relativity theory, as well as some of its cosmological and black-hole applications, with anyone having an abiding curiosity about the nature of our world.
