Title: Interesting if somewhat lightweight
Product review: I picked this one up at the science writing seminar a couple of months ago. It is an attempt to cover an elusive but scientific topic, light, in all its concepts and permutations. He goes from classical notions of light (the Greeks thought invisible rays from our eyes made things visible) to the modern, quantum theory of light. He covers the creation of light, from torches and candles to gas lights to electric to lasers. He touches briefly on why things have colors (too brief for my taste, actually - I would have liked to learn more). He shows how light has been depicted in art, with examples from sources as diverse as Edward Hopper, Vincent van Gogh, and M. C. Escher. It makes for an interesting if somewhat lightweight overview - well worth reading and well-written.
