Physicist Haisch thinks "Let there be light" isn't just a randomly chosen phrase for the Creation. Indeed, he believes that in the mysteries of light rest clues to the deepest mysteries of the universe, something he calls God, though he doesn't mean by that word the personification that some believers prefer. A scientist who has worked in astrophysics and theoretical physics, Haisch has retained his wonder at the universe from childhood, as he describes in the affecting memoir with which the book begins. Many scientists find no tension between their profession and the profession of belief in divinity, but Haisch goes one step further by attempting to find a scientific explanation for the phenomenon generally called God. Light, that familiar but utterly mysterious force, is the key to such an understanding. Readable and engaging, Haisch will be embraced by those concerned with finding ways of reconciling science and religion. Patricia Monaghan
