The Gravity of Math: How Geometry Rules the Universe

One of the preeminent mathematicians of the past half century shows how physics and math were combined to give us the theory of gravity and the dizzying array of ideas and insights that has come from it In 1915, Albert Einstein published his field equations of general relativity, which transformed our conception of gravity. Rather than being a mysterious force that pulls objects together, gravity, Einstein proclaimed, is merely a consequence of the curvature of space and time. Gravity, in other words, springs from geometry itself. In The Gravity of Math, the writer Steve Nadis and mathematician Shing-Tung Yau show how Einstein formulated his revolutionary theory, building upon the prior work of Bernhard Riemann, with help from Marcel Grossmann, David Hilbert, Tullio Levi-Civita, and other mathematicians. The book explains how the implications of Einstein's theory have been, and continue to be, uncovered by mathematicians to help us understand phenomena like black holes, gravitational waves, and the Big Bang. The story of gravity also sheds light on one of the most profound questions of science: Why do our best descriptions of the physical world reduce to mathematical statements? Whatever the answer, one thing is clear: gravity shapes the universe on the largest scales with a reach that is seemingly boundless. So, too, is the reach of mathematics, which can carry us to the edge of infinity and back.
