QUESTION: If you had the opportunity to travel back in time to 1915 and sit with Albert Einstein for three hours—with the opportunity to bring him three books, magazines, photos or manuscripts published within the last 15 years—what books would you bring to him that you feel may give him a headstart on a few of his own theories?
One winner will be chosen on Halloween and the winning answer will be announced here on the Dr. Kaku's Universe blog.
If you don't wish to receive the four magazines listed (Wired, Discover, Inc. and Popular Science) -- You may also have the option to choose a SINGLE subscription to one of the magazines below.
