Last travel related thing. I have a friend who is about to get their fourth citizenship (among them US, all of them there are legit reasons for having gotten). Made me realize that the set of sets of compatible citizenships form a simplicial complex (some are not compatible with others).

I would’ve done EE (and then probably ended up in software anyways) if I could do it over. I’ve always found hardware things interesting and EE people seem to be consistently be among the smartest that I know

Now I know about the Baker-Gill-Solovay theorem. I vaguely knew that relativization was a barrier to a whole class of proofs but never really knew what it specifically meant pages.cs.wisc.edu/~jyc/02-810n...

I'm only through the first lecture but I was reminded of the Picard-Lindeloff theorem: en.wikipedia.org/wiki/Picard%... and this is the first time I've heard of the Euler-Maruyama method (for numerically integrating SDEs)

Not sure how common the “math is sexy” type shirt is (could be very common) but ND math did these soon after I graduated and I liked it enough to buy one. It’s faded, so I’d like to get another like it someday. (meant to reply to this post days ago then got distracted)

wild start to the season
apnews.com
Week 1 gets its signature moment when No. 16 Michigan beats Western Michigan on disputed finish
And to think, Kyle Whittingham said he wanted to put an end to all the drama around Michigan. Nobody could have scripted a more dramatic finish to the former Utah coach’s Michigan debut.
