Light and Dark

With more than 100 diagrams, graphs, and figures, the subjects discussed include the history of artificial lighting, eclipse cycles, glasses that go dark in sunlight, rainbows, chiaroscuro art, bioluminescence, the clock setting at the South Pole, zebra stripe patterns, lighthouses, color perception, the harvest moon, and how information and speech can be conveyed by light from the sun or from a laser. The book examines many familiar phenomena, such as the variations in the duration of twilight through the year and the ability of human vision to misinterpret patterns of lines under certain conditions.
