Quantum physics is not mystifying. Its implications may be mind-bending, and not yet fully understood, but the theory is illuminating. It is the best explanation of reality we have. And no, God does not play dice with the universe. Spanning the history of quantum discoveries, from Einstein and Bohr to the present day, this is the essential guide to the most intriguing subject in science. Carroll debunks the myths that have grown up around quantum physics, resurrects and reinstates the Many-Worlds Interpretation, and presents a new path to solving the apparent conflict between quantum mechanics and gravity. A magisterial tour, Something Deeply Hidden encompasses the cosmological and everyday implications of quantum reality. And, finally, it all makes sense.
