Harvard mathematician Dan Freed on QFT through a mathematician's lens, 475 AI-written math papers, and math after AI
TOEwithCurt · x · 2026-11-12
A podcast conversation with Dan Freed, Harvard mathematician and director of its Center of Mathematical Sciences and Applications, explaining quantum field theory as a mathematician sees it — and what mathematics looks like after AI.
Topics include:
- Why with QFT "you never see the whole elephant";
- Why quantum mechanics is projective, and when an anomaly is a feature rather than a bug;
- The anecdote that Witten's Chern-Simons talk took shape overnight after a pub dinner with Atiyah and Segal;
- What makes dimension four so strange;
- The 475 AI-written math papers and whether mathematicians should mourn the old way of working;
- What Isadore Singer taught Dan about the freedom to err.
