The quantum world is not made up of objects. - Nick Herbert

Physicists cannot explain atoms to their children, not because we are ignorant but because we know too much.

Quantum physics emerged from the Stone Age with an embarrassment of riches - three quantum theories, each claiming to explain the world. As it turned out, all three were right.

The entire visible universe, what Bishop Berkley called "the mighty frame of the world," rests ultimately on a strange quantum kind of being no more substantial than a promise.
