By the end of this conference, Einstein had lost a battle and our understanding of the world changed forever. Quantum mechanics, in a nutshell, is the physics of the very small,” says John Gribben, author of In Search of Schrodinger’s Cat. “Anything as small as an atom, or smaller than that, works in the rules of quantum physics.”
