In an ideal world, an action this drastic would make T&F seriously reconsider its relationship with the journals it manages. But, I'm afraid that they will just find a new group of editors and carry on like nothing happened.

Sent out my very first editorial request to a referee today, and then Karma struck and I ended up with a request to referee an article for a different journal.

People calling Philip Rivers grandpa and he's a year younger than me. To be fair, he's an actual grandpa, which is crazy. My little one still has kid YouTube.

Quiver down-up algebras
We present a generalization of down-up algebras, originally defined by Benkart and Roby. These quiver down-up algebras arise as quotients of the double of the extended Dynkin quiver of type $A$. Under...

Book #17 of 2025: The Candy House by Jennifer Egan. I thought this would be a bit more black-mirror-esque. Still a great read.

AI is coming for us all.
AI Overview (from Google): 300 words is approximately one page, single-spaced, or about one-third of a page, double-spaced, depending on formatting and font size. Written out, it takes about two minutes to speak at an average pace.

DSM to ORD was delayed, so I'd miss my 6pm to DAY. Got booked on an 8pm ORD to DAY, which was canceled 15 minutes later. Booked for next day 8am to DAY. That was canceled shortly after I got to ORD and then booked a 6pm next day. An agent this morning got me on an 11am that wasn't an option before.

Trying to teach my students good notation then the book goes and uses B for a basis AND B for the matrix whose columns are the vectors in B. #mathsky

Doing mandatory grant training through Workday. Any purchase under $10,000 is a "micro purchase" and a "small purchase" is between $10,000 and $250,000. Considering the size of my grant, I don't think most of this presentation applies to me.

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 #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.
