There are two scientific theories that, taken together, explain the entire universe. The first, which describes the force of gravity, is widely known- Einstein’s General Theory of Relativity. But the theory that explains everything else-the Standard Model of Elementary Particles-is virtually unknown among the general public.In The Theory of Almost Everything, Robert 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 twentieth century. Rich with accessible analogies and lucid prose, The Theory of Almost Everything celebrates a heretofore unsung achievement in human knowledge-and reveals the sublime structure that underlies the world as we know it.
