Praise for the original edition: This work is full of interesting problems, arranged by subject and graded by difficulty. It is full of intellectual content, and it is much more than modern pedagogy. It is modern physics, much of it at the frontiers, done in modern ways. -John A. Wheeler, Princeton University When you first meet them, special and general relativity seem absurd and paradoxical. When you finally reach the point of understanding them, they make perfect sense, but the only way to get there is by solving problems. This classic text is an invaluable resource for students wanting to make this journey. -John Baez, University of California, Riverside This book is a classic and easily the best way for students learning general relativity to get experience doing problems. A wide variety of topics are covered and extensive solutions are given to the insightfully formulated exercises. This is a wonderful tool for becoming an expert in a beautiful subject. -Sean Carroll, author of Spacetime and Geometry: An Introduction to General Relativity
