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

    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. 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.

    266 - Annaka Harris: The Fundamentality of Consciousness

    Annaka Harris is the New York Times bestselling author of CONSCIOUS: A Brief Guide to the Fundamental Mystery of the Mind and writer and producer of the audio documentary series, LIGHTS ON. Her work has appeared in The New York Times, Nautilus Magazine, the Journal of Consciousness Studies, and IAI Magazine. She is also an editor and consultant for science writers, specializing in neuroscience and physics. In this episode, Robinson and Annaka discuss panpsychism and the case that consciousness is fundamental. More particularly, they talk about complexity and emergence, the relationship between consciousness and physics, and artificial intelligence.

    265 - Jacob Barandes: A New Foundation for Quantum Mechanics

    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.
