“In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary living—in this system of fine and finer, where then is the substance of a thought?”
—Doris Lessing (b. 1919)
“It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom’s way of knowing about atoms.”
—George Wald (b. 1906)
