121 - Julian Barbour: Thermodynamics, Boltzmann Brains, and a New Theory of Time

Julian Barbour is a physicist working in the foundations of physics and quantum gravity, with a special interest in time and the history of science. In this episode, Julian and Robinson discuss thermodynamics and the arrows of time, including a new theory of time developed by Julian and his collaborators, which is laid out in his book, The Janus Point: A New Theory of Time. If you’re interested in the foundations of physics—which you absolutely should be—then please check out the John Bell Institute (Julian is an Honorary Fellow at the JBI), which is devoted to providing a home for research and education in this important area. At this early stage any donations are immensely helpful.
