With competing ideas of how to interpret the meaning of quantum mechanics, physics is in crisis. Can an ancient concept known as the One, rescue physics. From Bohr's Copenhagen interpretation to the Many Worlds theory put forward by Hugh Everett, to the seemingly intractable problem of quantum gravity the challenges facing physics threaten to tear down the very foundation of the science.

In an attempt to save physics from itself, Heinrich Päs has written a compelling book, The One, that offers a solution rooted in the concept that everything we see in the universe, including ourselves, emerges from the One and surprisingly the One itself is made up of everything that we see. How is this possible? Päs proposes that quantum mechanics can show us the way to the answer once we accept that the universe is one.
