This book, written for the general reader, explores the fundamental issues concerning the nature of time and space, and quantum mechanics. It shows how physics and philosophy work together to answer some of the deepest questions ever asked about the world.

"Huggett's writing style is clear and accessible, the examples are plentiful and helpful, and the overall narrative structure of the book is successful, with each chapter leading to the next." --American Journal of Physics

Selling point: shows by example (and by explaining key ideas for the layman) how to think philosophically about physics Selling point: explains the dialogue between physics and philosophy; works through problems to show how each can influence the other
