Already climbing the bestseller lists-and garnering rave reviewsâ€”this "little masterpiece" sheds brilliant light on the equation that changed the world. Bodanis begins by devoting chapters to each of the equation's letters and symbols, introducing the science and scientists forming the backdrop to Einstein's discoveryâ€”from Ole Roemer's revelation that the speed of light could be measured to Michael Faraday's pioneering work on energy fields. Having demystified the equation, Bodanis explains its science and brings it to life historically, making clear the astonishing array of discoveries and consequences it made possible. It would prove to be a beacon throughout the twentieth century, important to Ernest Rutherford, who discovered the structure of the atom, Enrico Fermi, who probed the nucleus, and Lise Meitner, who finally understood how atoms could be split wide open. And it has come to inform our daily lives, governing everything from the atomic bomb to a television's cathode-ray tube to the carbon dating of prehistoric paintings.
