Dror Bar-Natan: What Knots Reveal About Quantum Field Theory

Dror Bar‑Natan explores the deep connections between knot theory and quantum field theory, discusses insights from Ed Witten and Eric Weinstein, and reflects on the nature of mathematical research and teaching. He also shares personal routines, thoughts on creativity, and the philosophical implications of mathematics.- 00:00:00 - Introduction- 00:03:29 - Quantum Field Theory and Knot Theory- 00:10:19 - Another QFT / Knot Theory connection or analogy- 00:20:46 - Knot Theory and Gravity + Bar‑Natan's PhD on Chern‑Simons- 00:24:08 - Homology and Cohomology- 00:32:54 - Dror's average day / routines / laziness- 00:35:23 - What is "work" for a Professor?
