bike 1:11 [2] 22.43 km (3 / km) +194m 3 / km
Out on my new old bike, Specialized Epic. Seems pretty nice, just the right-hand gear changer doesn't always want to work...
Hit the absolute apex of my mathematical career today. Amongst the audience, professors, a Faddeev, a Fields medallist, in a packed seminar room; speaking, another Fm. One question from the speaker. I answer, correctly. Oh the glory!
The masterful talk went from quantum mechanics to braid theory via quantum field theory, von Neumann algebras, sub-factors, conformal field theory, Block spin renormalisation and more. Whatever that means. The question, somewhere in the middle: what is $4\cos^2(\pi/3)$?
