David Mermin's new book is a gem. Requiring nothing more than a basic understanding of algebra, it provides the clearest and most insightful treatment of special relativity I've ever encountered. Students new to special relativity should learn it from this text; those already familiar with the subject should read this book to enhance their understanding and (of equal importance) to experience the craft of a master teacher.—Brian Greene, Columbia University"This book includes material that is intellectually innovative and comes as a surprise even to specialists in the field. Its uniqueness, its insights, and its wonderful style will likely make it a classic."—Richard Price, University of Utah"Well-written, chatty and engaging, this book will be accessible to scientists and non-scientists alike."—Robert Geroch, University of Chicago"The reader who works through this book carefully will have quite a good understanding of what special relativity is all about. It offers a fresh approach to the subject."—Michael Strauss, Princeton University
