How math helps us solve the universe's deepest mysteries. You must be able to test any physical theory in the real world. To most physicists, this is obvious. But since the 1980s, experimental physics has yielded vanishingly little insight into the fundamental physics of the universe. Meanwhile, some physicists have begun to probe the universe not with proton beams, but with pure math. They're less concerned with testable theories than with the drive to explain nature with mathematical beauty. This approach is often pilloried by traditional scientists, who point out that such approaches have yet to make a correct prediction about the real world. But in The Universe Speaks in Numbers, Graham Farmelo offers a gripping tour of the history of math-based physics and explores why it may be the key to the next big breakthrough in our understanding of the nature of reality
