You are surrounded by space on all sides and immersed in time 24 hours a day, 7 days a week. But, do you really understand it? Is it really 4-dimensional or merely our perception of an 11-dimensional reality? Brian Greene, one of the world’s leading physicists, thinks that he knows and he explains it all to you. Using super-strings and M-theory, Greene tries to close the gap between quantum mechanics and Einstein’s general theory of relativity. Granted that probably is not very interesting for most people, but with wit and humor he is able to translate the mathematics and physics of the universe into analogies which are accessible by the layperson.
