Before and Beyond Thomas Levenson Lecture: “The Brief Life and Exciting Times of Vulcan — the Planet that Wasn’t There” Thursday, March 10, 7 p.m. Thomas Levenson, professor of science writing at Massachusetts Institute of Technology, discusses and signs copies of his book “The Hunt for Vulcan ... And How Albert Einstein Destroyed a Planet, Discovered Relativity, and Deciphered the Universe.” The planet Vulcan first appeared in our solar system in 1859 as the only sensible explanation for Mercury’s misbehavior. It disappeared for good in 1915, banished from reality by Albert Einstein’s general theory of relativity. In between, its story is one of perfectly sound science, vaulting ambition and persistent self-deception, adding up to a cautionary tale about how science actually works. Community Room
