Despite the fact that our lives are powered by electricity to an astonishing degree, most of us have little or no understanding of how or why it works. Instead, we rely on a blurry notion that it flows--like water--through wires to turn on our appliances. In Electric Universe, David Bodanis fools readers, by keeping them entertained and intrigued, into learning the science behind electricity. He does this by telling a series of stories, starting with how a backwoods American really invented the telegraph and how Samuel Morse stole the credit for it. From there, he works through the lives of Alexander Graham Bell, Thomas Edison, Michael Faraday, and other pioneers. He shows how their experiments affected their lives--never more poignantly than with the tragic story of Alan Turing, whose early work designing computers wasn't enough to prevent him from being driven to suicide. It's surprisingly easy to identify with some of these brilliant scientists, because Bodanis relates their failures as well as their successes. In the end, although we may continue using words such as "current" to describe the "flow" of electrons, Bodanis makes certain that we see electrical energy for what it really is, at a subatomic, quantum level. Even so, there's not a single boring bit in the book. Electric Universe is an excellent scientific history, one that reveals both the progress of knowledge and the strange science of the wiggling electrons that run our lives.
