The Proof in the Code: The Mathematicians

Johan Commelin, Kevin Buzzard, and Alex Kontorovich join Kevin Hartnett, author of The Proof in the Code, to discuss what it means to formalize mathematics in Lean, from large collaborative projects to the day-to-day experience of working alongside a machine that checks every step. Together they consider how computer verification is changing the way mathematicians collaborate, build trust, and decide what counts as proof.
