Скачать или смотреть Tim Maudlin: A Masterclass on General Relativity

Tim Maudlin is Professor of Philosophy at NYU and Founder and Director of the John Bell Institute for the Foundations of Physics. This is Tim’s seventh appearance on the show. He last appeared on episode 237 for a masterclass on Albert Einstein’s theory of special relativity, explaining it from the ground up and elucidating some common misconceptions. In this episode Tim returns for a discussion of another of Einstein’s major impacts on physics: his theory of general relativity. More particularly, Tim and Robinson discuss black holes, time, paradoxes of distance, Penrose diagrams, figures like Leonard Susskind and Richard Feynman, the curvature of space, and more. If you’re interested in the foundations of physics, then please check out the JBI, which is devoted to providing a home for research and education in this important area. Any donations are immensely helpful at this early stage in the institute’s life.
