DELIVERING far more than the title promises, Hoeppe’s book describes an intellectual quest that began with the ancients. He details our growing understanding of the sky’s light, and the insights and experiments that brought it about.

A well-illustrated, rewarding read that answers one of the most frequently asked questions addressed to Â鶹´«Ã½‘s The Last Word.
