Quantum physics is not mystifying.

The implications are mind-bending, and not yet fully understood, but this revolutionary theory is truly illuminating. It stands as the best explanation of the fundamental nature of our world.

'An authoritative and beautifully written account of the quest to understand quantum theory and the origin of space and time.' Professor Brian Cox

Spanning the history of quantum discoveries, from Einstein and Bohr to the present day, Something Deeply Hidden is the essential guide to the most intriguing subject in science. Acclaimed physicist and writer Sean Carroll debunks the myths, resurrects and reinstates the Many-Worlds interpretation, and presents a new path towards solving the apparent conflict between quantum mechanics and Einstein's theory of general relativity. In doing so, he fills a gap in the science that has existed for almost a century.

A magisterial tour, Something Deeply Hidden encompasses the cosmological and everyday implications of quantum reality and multiple universes. And - finally - it all makes sense.

'Carroll takes us by the hand and with a benign smile and a chatty style, leads us to a place where... at every instant an almost infinite number of copies of you are splitting off to live alternative lives... a wild conceptual ride.' The Sunday Times, BOOKS OF THE YEAR

'Like all great writers, Carroll has the remarkable ability of putting the reader utterly at ease with his lucid and addictive prose. He leads you so gently and comfortably into his quantum world that you quickly forget you are being given access to the most profound ideas about the nature of reality.' Jim Al-Khalili

'Sean Carroll's immensely enjoyable Something Deeply Hidden brings readers face-to-face with the fundamental quantum weirdness of the universe - or should I say universes? And by the end, you may catch yourself finding quantum weirdness not all that weird.' Jordan Ellenberg
