Offering an insight into "Time" magazine's "Man of the Century", Albert Einstein, this text covers topics such as late-20th century research on Einstein's brain, the possible collaboration of his wife Mileva in his work, and the love letters that Einstein sent to an alleged Soviet spy. Einstein continues to be a global icon as we enter the new millennium, and this 2nd-edition text attempts to show us why. The revelation that he was, after all, a human being in his personal life rather than a secular "saint" has detracted neither from his fame nor from his great scientific achievements. Above all, Einstein is shown to be a loyal letter writer, keeping up a lively correspondence with those whom he loved and respected, and expressing an opinion on just about everything and everyone, including himself.
