This resource aims to break down the construct of time in both its scientific and societal functions. The narrative begins with early man and moves to discuss the rudimentary devices—water clocks and sun dials—used by ancient civilizations, but moves forward, exploring clock making and the innovations that came in the Renaissance. The theories and discoveries of great scientists are expounded here in an easy-to-understand manner. The book concludes with a discussion of time travel and the concepts behind wormholes and black holes. Interesting sidebars, color photographs, diagrams, and a timeline help to make what could otherwise be a very dense and complex topic, an engaging package sure to stimulate the reader's notions of the often illusive topic of time.
