TBH, the 23% for the US is a lot lower than I would have expected. The 3% for Germany is surprising, but I bet it's in line with the number of people in the US that have never left their own state.

50 minutes goes by very fast. I find that in 75-80 minutes I can usually lecture and give students a chance to practice for 10-15 minutes in groups. But it depends on how much content is in the course.

Book #15 of 2025: The Midnight Library by Matt Haig @matthaig.bsky.social. Interesting concept that explores the nature of regret and the different paths our life can take.

It's hard to take a paper seriously when 10 of the 12 references are self citations.

Book #14 of 2025: Breakfast of Champions by Kurt Vonnegut. Probably my third or fourth read of this book. I need to make a more regular habit of getting to the Granfalloon in Bloomington every year. Last time I went I caught a fantastic concert by the Flaming Lips.

"You will become good friends with C[x_1,...,x_n], and friendly acquaintances with F_p[x_1,...x_n]." And then there is H[x_1,...,x_n], which is like the weird noncommutative uncle that sometimes shows up to family gatherings.

Book cover made to look like classic children's book. Title is "Everything I don't like is WOKE: A book for basic dickheads." Cover shows a boy pointing to the engine of a car saying "This engine is woke."

James Dobson Is Dead, Was A Monster | Defector James Dobson was a nasty dude. He liked to beat children and dogs with a belt and to rain misery and punishment on the vulnerable; we know all of this about him because he said as much in public,โ€ฆ

Book #13 of 2025: We Were Eight Years in Power by Ta-Nehisi Coates. Such a fantastic writer. He lays out in full view the lingering effects of slavery today. Also be sure to check out his Black Panther run. #booksky

Screenshot of text. The relevant part is "Note we are using the convention that pq means p then q; be aware that some savage barbarians use the opposite convention." There is a footnote marker by "savage barbarians."

The footnote: "you know who you are"

Trying to understand a theorem led me back to one of my favorite bits of math writing. There are two ways to compose paths in a quiver and my confusion traced back to the fact that the authors were using function notation. #mathsky

BTE is still around. Saw them at Summerfest last year and there was quite the crowd.

I might be a bit of a fanboy though.

Book #12 of 2025: Girlfriend in a coma by Douglas Coupland. I think I missed the point. Also I've been slacking on summer reading. Too much #math. #booksky

Kind of over-the-moon about this. This was my third attempt at this (plus many other grant attempts that didn't work out). We need more grant opportunities like this to support mathematicians in the US. Thanks to @amermathsoc.bsky.social and @simonsfoundation.org! #mathsky #academicsky
