Efforts to Ground Physics in Math Are Opening the Secrets of Time
Now, three mathematicians have finally provided such a result. Their work not only represents a major advance in Hilbert’s program, but also taps into questions about the irreversible nature of time. “It’s a beautiful work,” said Gregory Falkovich, a physicist at the Weizmann Institute of Science. “A tour de force.” Under the Mesoscope Consider a gas whose particles are very spread out. There are many ways a physicist might model it. At a microscopic level, the gas is composed of individual
