101 — How Will AI Change Physics? (Ft. Yoni Kahn)
In 2023, Dan made a bet with physicist Yoni Kahn about whether AI would be able to pass a graduate-level quantum field theory course by 2026. Today on the show, they revisit their bet and discuss what AI is capable of in physics today, and how it might change the field moving forward. Support the show

100 - What is Light? A Journey from Ancient Philosophy to Quantum Physics
Modern physics tells us a lot about light; that it's both a wave and a particle, and that it sets the speed limit of the universe, for example. But how did we come to understand light in this way? In Dan's first solo episode, he takes us through theories of light through the ages, starting from the earliest accounts of ancient ideas and bringing us all the way to modern times. Let us know what you think about this new format! Support the show

96 - The Making of Particle Fever (Ft. David Kaplan)
In the years leading up to the Large Hadron Collider turning on, the physics community was buzzing with curiosity and excitement about what they were about to discover. These moments were captured in the documentary Particle Fever, created by the particle physicist David Kaplan. On today's episode, he recounts these historic years from the perspective of both physicist and filmmaker.
