Jacob Barandes is Senior Preceptor in Physics at Harvard University, where he works widely across the philosophy of physics, with focuses on the foundations of quantum mechanics, the philosophy of spacetime, and the metaphysics of laws. In this episode, Robinson and Jacob focus on the foundations of quantum mechanics. They discuss the importance of history and philosophy in the same, its connections to mathematics, many of the biggest puzzles in quantum physics, and Jacob’s new approach to the foundations, which he refers to as the “Indivisibility” approach.

Robinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University, where he is also a JD candidate in the Law School.

Lee Cronin is Regius Chair of Chemistry at the University of Glasgow. Among his many pursuits are the digitization of chemistry, the discovery of alien life, and the creation of artificial life. In this episode, Robinson and Lee focus on astrobiology, the chemistry of life as we know it, and the controversies surrounding artificial intelligence.

Sara Imari Walker is Professor in the School of Earth and Space Exploration at Arizona State University, where she is Deputy Director of the Beyond Center. Sara is an astrobiologist and theoretical physicist, with research interests in the origins of life, artificial life, life and detection on other worlds. In this episode, Robinson and Sara discuss the physics that makes life possible. More particularly, they discuss assembly theory, the growing field of astrobiology, the difficulties of defining life, and where we are most likely to find aliens. Sara’s latest book is Life as No One Knows It: The Physics of Life’s Emergence (Riverhead Books, 2024).
