Episode notes

My halfway informed feeling is that Bomi mechanics looks quite natural in the non-relativistic regime. And it's a little bit more of a challenge to see how we should just do quantum field theory in that picture. Standard quantum field theory has been plagued by mathematical problems and run away singularities, numbers you try to calculate, and they all come out infinity. It's not as if it's all conceptual lightness and clarity in the so-called standard picture.

Last year's Nobel Prize for experimental tests of Bell's Theorem was the first Nobel in the foundations of quantum mechanics since Max Born in 1954. Quantum foundations is enjoying a bit of a resurgence, inspired in part by improving quantum technology but also by a realization that understanding quantum mechanics might help with other problems in physics (and be important in its own right). Tim Maudlin is a leading philosopher of physics and also a skeptic of the Everett interpretation. We discuss the logic behind hidden-variable approaches such as Bohmian mechanics, and also the broader question of the importance of the foundations of physics.
