The Problems of Physics, Reconsidered

Open Agenda 2021

The Problems of Physics, Reconsidered is based on an in-depth filmed conversation between Howard Burton and Physics Nobel Laureate Tony Leggett. The basis of this conversation is Tony Leggett’s book The Problems of Physics and further explores the insightful plain-speaking itemization that he developed of the physics landscape according to four basic categories—the very small (particle physics), the very large (cosmology), the very complex (condensed matter physics) and the very unclear (foundations of quantum theory)—while providing a thoughtful follow-up analysis from a contemporary perspective to assess how much progress we’ve made and which mysteries remain or have come on the scene since the book was published.

Howard Burton is the founder of the Ideas Roadshow and host of the Ideas Roadshow Podcast. He can be reached at
