Although early civilizations knew what light was and how to use it, the ancient Greeks and Romans were the first to try to find out how and why light worked as it did. Eventually, scientists realized that light is a form of radiation similar to radio waves and X-rays. This book traces the history of discoveries about light from ancient Greek theories to the development of quantum mechanics.
