It encompasses a large cast of characters who interact with all facets of the history of mankind. The anecdotes presented here describe a few of the events that took place in man's search for the nature of light -- a search which included drama, adventure, humor, political and religious entanglements, pestilence, and the many foibles of men."" The resulting compilation is sure to motivate readers in their own explorations of this age-old question.
