There are two scientific theories which, taken together, explain the entire universe. The first, which describes the force of gravity, is widely known: Einstein's Theory of Relativity. But the theory that explains everything else - the Standard Model of Elementary Particles - is virtually unknown among the general public. Here, Oerter shows how what were once thought to be separate forces of nature were combined into a single theory by some of the most brilliant minds of the 20th century. Rich and accessible prose makes this a truly readable book.
