Today I gave a talk entitled “Studying Topology Change with Topspin Networks” during the LOOP13 conference at the Perimeter Institute:
This is the entire session; I start around minute 43. The talk was in the wrong session and late in the conference, and was thus not too well attended. However, the discussion at the end was very nice, and despite me saying a few strange things (“topologically zero fundamental group”? Even worse, I said “homeomorphism” and meant “homomorphism”…that’s a kindergarten math mistake people).
In retrospect, do not let anyone tape you giving talks, ever.
