3 very different races tomorrow: 1. Tadej Pogacar trying to win his missing cycling monument at Paris-Roubaix: www.paris-roubaix.fr/en 2. Hungarians trying to get rid of their strong-man authoritarian: www.theguardian.com/world/2026/a... 3. Me trying to run 10 miles cherryblossom.org/pre-race/eve...

Makes me a little sad that both Banksy and Bitcoin founder Satoshi Nakamoto have been (probably?) identified. I think I preferred haunting mystery. www.nytimes.com/2026/04/08/b... www.reuters.com/investigates...

Hey #FIFA - how's that Peace Prize looking now that the recipient has bombed a country for a month and threaded to wipe an civilization off the map?

Ahead of the SCOTUS arguments about birthright citizenship: when I was born (in Wisconsin) my father was not yet a citizen - just like John Roberts' grandfather. What's your immigration story?

Just a reminder that TPSE Math has stats about the proportion of college grads getting math and math/stat degrees - not just nationally, but for every institution (averaged over a four year period). Super interesting to see the variation across states/institutions. www.tpsemath.org/math-vs-math...

I'll be out there at my local NoKings protest. Who else?

BREAKING: There are now 3,267 #NoKings protests now on the map for THIS SATURDAY March 28. Find yours at NoKings.org.

I'm definitely late to his party: they identified Banksy? That makes me kind of sad. The mystery added to the experience of the brilliant art - at least for me. www.reuters.com/investigates...

Funding your opponents? Sounds more like "losing" than "winning."

It's been a while since I biked down to catch the sunset - this time from Historically St Mary's City.

Wonderfully touching, thoughtful, poignant view of the reckless unserious leadership that has gotten us into this war. If you haven't taken the 3 minutes to watch this, you should. www.youtube.com/watch?v=G-9i...

Happy Pi Day!

In 2025, leading mathematicians met in secret to test a new AI model. Its proofs sounded like those of a real mathematician presenting a complex argument. But were we giving it more credit than it deserved? Are we at risk of accepting proofs we can’t understand? 1/10

Every one of us tax-paying Americans paid to send a tomahawk missile into an elementary school killing ~100 kids. Let that sink in.

Maybe you can go home again. (Watertown SD.)

I'm against this illegal war.

Super excited about the new @joinmaa.bsky.social leadership!

As a child of the 80's I object!

Masterful Troll, TCM.

新年快乐! Happy New Year!

I'm generally impressed with NYTimes readers - great comments, impressive stats in games, etc. But this question really just asks you to divide 1980 by 360 – and only 36% got it right. What do you think. Most people didn't know how to interpret 1980? Couldn't/didn't do the division right?

It's true that the "grrrrrr" sound I made isn't a very good example of what I was going for... #BeeMoan

I don’t really know what I expect in posting this, but maybe some people see it and can learn from it. I’ll call it “lessons from an unwilling immigration attorney.” 1/

"In Vibe-Teaching™, faculty are no longer required to read the AI-generated slop that students themselves have not paused to read. " Hilarious satire about what teaching in a time of AI might become. (Also: excited that a friend got a piece into @mcsweeneys.net!)

Skating commentary: "He rotates at over 300 rpms. That's faster then they sprint at the Tour de France." What does that even mean? Can we compare one person's height to another's weight? #Olympics #CommentaryFail

Could we please start calling them what they are: concentration camps? (They aren't death camps...yet.)

It's clear that one of the richest men in the world is valuing disinformation over information. Not good for democracy.

#DefundICE Just spent 2 minutes leaving messages for both of my Senators asking that they vote against upcoming appropriations bills that include any money for the force terrorizing American citizens in Minnesota. Find your Senator and call today! www.senate.gov/senators/sen...

I have a (disturbing?) love of bad weather runs. Yesterday it was 24 degrees and raining for my 4+ mile jaunt on trails at Historically St Mary's City. So. Much. Ice.

A movie about the first woman Fields medalist? Yes please!

Some thoughts on Martin Luther King today, informed by the way I learned history as a kid and the truth of how history is made I've learned in this job - and from the honor of having been able to serve with and meet many of the foot soldiers who worked along side MLK:

NEW An initially-secret report for Customs and Border Patrol in 2013 found: In many vehicle shooting cases, the “driver was attempting to flee from the agents who intentionally put themselves into the exit path of the vehicle, thereby … creating justification for the use of deadly force.” 🧵

Anyone else pick up a nast bug at #JMM in DC? The glue is currently kicking my ass.

Not a fan of strongman autocrats who usurp power from legal institutions. That applies to both Maduro and Trump. Happy to see the former deposed. Not happy with the murderous, illegal way it went down.

So much elementary celestial mechanics in one (massive, complicated) image!

To those who celebrate some arbitrary direction eminating from the sun that the Earth periodically passes... ..Happy New Year! 🎆🎉🍾

WTF? I don't think of gunnel as a very obscure word...

Sure would be a shame if we all made the 60 Minutes video go viral...

The UCSD report making the rounds (Atlantic, WSJ, Bloomberg) echoes what lots of math profs are saying: many students are arriving at college with placement tests suggesting significant gaps in basic math content. What's going on? What are the underlying causes? 1/2

Sporting my gear ahead of the @wisconsinbadgers.bsky.social vball final four vball match up (9pm ET). (My alma mater vs my dad's, Kentucky.) #GoBadgers!

A mathematician's take on the current healthcare debate: The point of insurance is to spread out risk. Lots of us contribute but only a few incur high costs which get covered. The ACA does that. Health savings accounts don't. How is that not the end of the argument?
