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.Julian’s Website: http://platonia.com/index.htmlThe Janus Point: https://a.co/d/4NVOGqqA History of Thermodynamics: http://platonia.com/A_History_of_Thermodynamics.pdfQuantum without Quantum:  https://arxiv.org/abs/2305.13335The John Bell Institute: https://www.johnbellinstitute.orgOUTLINERobinson’s Website: http://robinsonerhardt.comRobinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.
