Just finished reading "EINSTEIN" by Walter Isaacson this past weekend, and I thoroughly enjoyed it. I was thinking that it would be difficult to really capture the spirit of the actual person, since his great achievements in Physics would cloud objectivity. To even describe his discoveries in layman's terms would be a daunting task, but Isaacson did an excellent job. Instead of the dry textbook type of biography this book read like an adventure. And the best part, in the end I even liked and respected Einstein more for his humanity.
