Oh, hey, it’s @uwmadisonmath.bsky.social’s @jsellenberg.bsky.social getting elected to AAAS!

Well, well, well... the deadline for compliance with the new Title II accessibility guidelines has been extended by a year (or two, depending on the size of your organization)

Blue Hour View from the Citadella In honor of Hungary 🇭🇺 voting to stand for freedom and democracy yesterday, here’s a shot from my recent trip. Pentax K-3 iii smc Pentax-DA 18–270mm at 88mm stitched to a panorama in Lightroom Classic

Spent five nights in Budapest during Spring Break, leaving on April 2nd. Hungary is a wonderful country, and as a mathematician, I have had more opportunities than most Americans to get to know Hungarians. (My academic brother is Hungarian and my office neighbor at UW is as well.)

I always forget that I share a birthday with Sam Alito until social media reminds me. @maddow.bsky.social is also in the April Fool’s Day baby club, too, which I appreciate more.

had a dream where i was taking a math final. on page 2 was a problem i immediately recognized as an "x choose y" problem @mitchkeller.phd

That last sentence! (Read the whole piece, please.)

This is undoubtedly the home of the Math Department at Bee State University.

Always read Chris’s reporting, but today make sure you make it to the end for the courthouse mystery!

This semester I'm teaching combinatorics. I'm using my own open-source text (appliedcombinatorics.org) I have lost count of how many times I've taught combinatorics, and yet most semesters, I discover something new along the way. Thought I'd thread a little discussion of what I came across today 1/9

Dr. Camille McKayle has been named the next Executive Director of the MAA, effective September 1, 2026. A mathematician and experienced STEM leader, she brings deep commitment to mathematics education and the mathematical community. Read more: https://bit.ly/4kUylOU

We in @uwmadisonmath.bsky.social are excited to launch a new MS in Applied & Computational Math this fall. The program offers modern training in applied & computational math and data‑focused quantitative skills, designed for students with strong math or quantitative backgrounds. Please share widely!

Okay, this is quite outstanding from Bedford Council.

Two @uwmadisonmath.bsky.social colleagues on this list!

I just saw a bunch of the credulous reporting on this new conflicts check system, and, my god, it's so embarrassing. Please, read and subscribe to Law Dork for independent legal journalism. Save yourself from the bullshit.

Yes, Mister Bunny’s performance was obviously political. But I think everything short of gargling a meth addicted klansman’s truck nuts comes across as an implicit denunciation of the president nowadays.

I took my time with this one — almost as much time as Jones took after arguments to write her opinion backing Trump — because I think it’s a very important, alarming ruling. So, yes, I hope folks do read this. www.lawdork.com/p/fifth-circ...

House Minority Leader Hakeem Jeffries (D-N.Y.) on Thursday said House Democrats will demand that CBP be banned from squaring the circle, trisecting angles with straightedge and compass.

🤦‍♂️ Sadly, there were 44 comments before mine, and I was the first to point out that this is nonsense.

This sure seems more like the tyranny the Constitution is supposed to protect against than forgiving student loans.

Sure would be nice if Georgia Tech undid all their hasty complying in advance that destroyed the Women’s Resource Center, LGBTQIA Resource Center, Office of Minority Education, etc. etc. etc.

A few months ago, ICE hired me I didn't sign and submit any paperwork. I almost certainly failed the drug test. I'm real outspoken about my opposition to the Trump administration, and I am extremely googlable And yet, there it was, in plain English. "Welcome to ICE!" My latest for Slate

Or conferences organized by international professional societies

Festive baking! Dessert after Christmas dinner tonight was @americastestkitchen.com Mini Peanut-Praline Chocolate Pies. Three fun techniques: mini pie shells baked on inverted muffin tin, hard caramel + peanut butter in food processor for praline, and namelaka (~ganache with gelatin).

Sign you had a bunch of awesome students this semester: a third of them were hanging out in the lobby after the final talking about the questions and then just wanted to keep chatting with you for like half an hour. (Only 5 stayed that long, but that’s still nearly 20% of the class.)

Student: "This is so much easier than what ChatGPT told me." Student a few min later, looking at Test I: "Wait, so is what I wrote here based on what I learned from ChatGPT correct?" Me: "Seems you 'learned' that material then in same way ChatGPT 'learns' things. But now you really understand!"

Hate week

Embarrassing last three games for Georgia Tech. Thank goodness for my NDSU Bison, who are one of two FCS teams to finish the regular season undefeated. #1 seed and home field advantage for the playoffs to be confirmed tomorrow afternoon!

GOOD MORNING WE HAVE ONLY ONE OBJECTIVE TODAY: WIN GET TO CAMPUS. FIGHT. WIN. DRINK. don’t get naked you’ll be arrested but DRINK MORE don’t get more naked we’re still not sure what that actually means whatever ITS GAMEDAY AT SOLD OUT BOBBY DODD LETS GOOOOO

Breaking News: Mayor-elect Zohran Mamdani is going to require all New York elementary school students to learn Arabic numerals. The madrasa indoctrination is starting very early. (This post is a test.)

Yesterday there was discussion of campus curriculum management tools as nemeses. Today I was one of four participants in a 75-minute meeting about the guts of our degree audit system. They can only update audit encodings in VMs because the software runs on Windows XP. Some backend code is COBOL.

Last night, the Northern Lights showed their true colors over campus and bathed the sky in Badger red. We’re still in awe. Photos by Paige Valley and Xiaomeng Shen | UW–Madison

This needs more attention: Zohran SPLIT the straights with Cuomo. ALL of his margin was from LGBTQ+ voters. Every Dem who ever said “we should abandon the transes” needs this shoved down their fucking throat with a ramrod.

We are fond of saying in @uwmadisonmath.bsky.social that “Learning support is for everyone!” We hire advanced undergrads to tutor as course assistants for most major-level courses, and many of our course assistants for the early tier of major courses get help from CAs for the more advanced courses!

Alabama tortured a man to death tonight. The “pro-life” Catholic majority on SCOTUS let a state murder a man by suffocation tonight. The death penalty is deeply immoral, no matter how it is administered. AL knew this would be torture & reporting suggests it was worse than J. Sotomayor described.

In July, I planned to spend this weekend in Chicago because I wanted to attend Open House Chicago and see Sarah Millican. I booked a tower room at Pendry Chicago in the iconic Carbide and Carbon Building. It was lovely weekend, and I’m glad that I was able to manage my Charlottesville 2017 PTSD

nothing bad ever happens to the Georgia Bulldogs football program

if you ever score a touchdown against Georgia the SEC will make sure you did not

Our flock is growing, thank you to everyone who has gifted to us so far! There is still plenty of time left to give a gift to the math department and get your flamingo; the link to give is in our bio! #uwmadison #flocktober #fillthehill #mathematics

Today is the 109th anniversary of one wild day in football

We are thrilled to announce that our NEW Large Language Model will be released on 11.18.25.

GEORGIA TECH WINS

Congrats to @uwmadison.bsky.social @uwmadisonmath.bsky.social professor Betsy Stovall!

SET WRECK TO MAXIMUM RAMBLE

Gotta say that Madison’s flag looks pretty cool and the professional vexillologists agree! (This version is only 7 years old, but it’s a light modification of a 1960s original design.)

🤦‍♂️ Guess I’ve got a new example for when I teach graph theory in my combinatorics class this fall, @magnacartergt.bsky.social

The death penalty is immoral in all circumstances. That republicans seem to have turned executions into a fetish is something I am at a loss for words to describe.
