#60 Exploring 'Mathlib' and the digitisation of mathematics: an interview with Professor Kevin Buzzard
In the latest episode of Living Proof, Dan Aspel speaks to Professor Kevin Buzzard of Imperial College London. Inspired by a lecture given by Thomas Hales at INI’s Big Proof (https://www.newton.ac.uk/event/bpr/) programme in 2017, Kevin has spent the past seven years working alongside fellow enthusiasts on the “Maths Library” project. In this conversation he explains the project in detail, touching on why the programming language of Lean was chosen, and how it interacts with his recent five-year grant to check the proof of Fermat’s Last Theorem.
If you have been inspired by Kevin’s story, make sure to visit the October 2024 INI research programme Big Specification (https://www.newton.ac.uk/event/bsp/), much of which will be available to watch via live stream on newton.ac.uk

54:48 - “I still wake up every morning thinking ‘I want to prove Fermat’s Last Theorem’”
