Patreon: https://bit.ly/3v8OhY7 Tim Maudlin is Professor of Philosophy at NYU and Founder and Director of the John Bell Institute for the Foundations of Physics. Sheldon Goldstein is Distinguished Professor of Mathematics at Rutgers University, where he researches mathematical physics, the foundations of quantum mechanics, and Bohmian Mechanics. He is also Board Member of the John Bell Institute for the Foundations of Physics, and this is his second appearance on the show. In episode 170, he and Robinson discussed Bohmian Mechanics. On the other hand, this is Tim’s fifth appearance on the show. Tim was also a guest on episode 46 (laws of nature, space, and free will), episode 67 with David Albert (the foundations of quantum mechanics), episode 115 with Craig Callender (the philosophy of time), and episode 142 on Bell’s inequality and the philosophy of science. In this episode, Robinson, Tim, and Shelly discuss the Copenhagen interpretation of quantum mechanics, the Many-Worlds theory, spontaneous collapse theories, Bohmian mechanics, and emergent relativity.

Michael and the Levin Lab work at the intersection of biology, artificial life, bioengineering, synthetic morphology, and cognitive science. Michael also appeared on the show in episode #151, which was all about synthetic life and collective intelligence. In this episode, Michael and Robinson discuss the nature of cognition, working with Daniel Dennett, how cognition can be realized by different structures and materials, how to define robots, a new class of robot called the Anthrobot, and whether or not we have moral obligations to biological robots.
