236 - David Albert: A Masterclass on Time’s Arrow

David Albert is the Frederick E. Woodbridge Professor of Philosophy at Columbia University, director of the Philosophical Foundations of Physics program at Columbia, and a faculty member of the John Bell Institute for the Foundations of Physics. This is David’s ninth appearance on Robinson’s Podcast. He last appeared on episode 221 to discuss the measurement problem of quantum mechanics. In this episode, David gives a pedagogical and introductory overview of the problem of time’s arrow, which is one of the most enduring of all physical and philosophical puzzles. David’s most recent book is A Guess at the Riddle (2023). 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.
