Here for the @amermathsoc.bsky.social sectional meeting in #StLouis. Awake because I'm on eastern time.

Would a micro pig be a micro purchase?

Oh, and the most useless was \tensor for \otimes

NCAlgebra @ncalgebra.bsky.social · 1d

Probably the most useful macro I've ever defined is \inv for ^{-1}

\cD

The little paper on the end of my tea bag string is missing. I can only surmise that I have somehow consumed it. Send help.

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.

Well, I got my 4 month math reviews reminder, so I guess that means I can delete my 2 month reminder. #mathsky

Krull versus global dimension in noetherian PI rings sounds like the title of a bad B-movie. #mathsky

Yesterday was a premier sports day, with #IU and the #Brewers both winning. Now we just need a #Packers win today to complete the trifecta.

If you're in #Louisville today, come check out the Louisville Book festival at the convention center and pick up a signed copy of #Mosaic by @lauragaddiswriter.bsky.social.

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.

Burning them is bad for the environment. Have you considered just eating them?

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.

Oh, so now my wife thinks we need to get our air ducts cleaned.

Picture from an ad of a red truck in front of a house advertising Duct Cleaning. At the bottom it says "Topless Service"

"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.
