This book invites the reader to understand our Universe, not just marvel at it.

Best-selling, accessible physics-first introduction to GR uses minimal new mathematics and begins with the essential physical applications.

Any necessary mathematical tools are user friendly provided, either directly in the text or in the appendices. This book is an introduction to the theories of Special and General Relativity.

A comprehensive review of the testing and research conducted on Einstein's theory of general relativity.

Based on graduate school lectures in contemporary relativity and gravitational physics, this book gives a complete and unified picture of the present status of theoretical and observational properties of astrophysical black holes.

This book introduces the general theory of relativity and includes applications to cosmology. The book provides a thorough introduction to tensor calculus and curved manifolds.

The first was practical to bring together and assess the wealth of data provided over the previous decade while realizing that newer data would come in even as the book was being printed.
