Warped Passages is a book about extra dimensions. Incredibly readable - and illustrated throughout - it allows the general reader to understand the questions that scientists are dealing with at the frontiers of research today. Lisa Randall gives an introduction to developments in early twentieth century physics, particle physics and string theory, including branes, and addresses current debates about relativity, quantum mechanics and gravity. She allows the reader to understand the kind of problems that extra dimensions might solve. And the kind of speculation that is needed to even imagine them. She also illustrates the questions that are still left wide open.
