270 - Tim Maudlin & Jacob Barandes: The Indivisible Approach to Quantum Theory

Description

Tim Maudlin is Professor of Philosophy at NYU and Founder and Director of the John Bell Institute for the Foundations of Physics. 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, Tim, and Jacob discuss Jacob’s novel approach to quantum mechanics, which he calls the “Indivisible Approach”. More particularly, they discuss the problems at the core of quantum mechanics, the ontology of the theory, causality and quantum phenomena, probability, and more.
