Some videos of me

Two videos of me. The first has plenty of editing to cut out my prolific usage of "uh". It's a general description of topology, intended for inquisitive non-experts.

And here's what I sound like giving a research talk with lots of "uh"s. The only thing I really want to edit in this talk is I should have said "index 1" when I said "index 2" when describing Yoshikawa diagrams.
