Generations have grown up knowing that the equation E=mc2 changed the shape of our world, but never understanding what it actually means and why it was so significant. Here, Bodanis writes the "biography" of this great discovery and turns a seemingly impenetrable theory into a dramatic and accessible human achievement. Bodanis begins by introducing the science and scientists forming the backdrop to Einstein's discovery. Having demystified the equation, he explains its science and brings it to life; making clear the astonishing array of discoveries and consequences it made possible and its impact on our daily lives. At last, the masses can understand that Einstein did nothing less than open the door to the inner structure of the universe.
