Look around you. The reflection of your face in a window tells you that the universe is orchestrated by chance. The iron in a spot of blood on your finger tells you that somewhere out in space there is furnace at a temperature of 4.5 billion degrees. Your TV tells you that the universe had a beginning. In fact, your very existence tells you that this may not be the only universe but merely one among an infinity of others, stacked like the pages of a never-ending book. Marcus Chown, author of ''Quantum Theory Cannot Hurt You'', takes familiar features of the world we know and shows how they can be used to explain profound truths about the ultimate nature of reality. His new book will change the way you see the world: with Chown as your guide, cutting-edge science is made clear and meaningful by a falling leaf, or a rose, or a starry night sky.
