I had the honor to deliver the Arnold Lecture 2024 on October 3, at Gonzaga University in Spokane, WA, USA. The talk was aimed at a general audience, and my topic was The magic of math: three-dimensional X-ray vision. Here are my talk slides: PDF 140MB.
I got excellent questions from the crowd, and this audience was extra skilled in solving my little tomographic mysteries. All in all, a very pleasant experience.
