One of my other favorite parts of ARML: when Bill brings his coffee and shares it with a bunch of us on Saturday morning 🙂

Off to day 1 of #ARML2025! We had a light prep day yesterday (because our site coordinator did so much ahead of time!). Starting this morning with unloading all the stuff we'll need for the rest of the weekend.

Before I get to Reno, time for an adventure. I've got a 4 hour layover in Vegas, so I'm headed out to my favorite sushi restaurant for lunch. And because this is a very Jet Lag: The Game move, I've dressed appropriately.

This weekend, over 1500 enthusiastic high school students from around the country and beyond will come together at five different locations for the annual American Regions Math League competition. This was always one of the highlights of my year as a student, and since then I've been fortunate...

I just saw a good example of what I was talking about with chatgpt being a crackpot generating machine. A guy had started Wheeler's Spacetime Physics, and had a problem on page 2. Wheeler expressed a square root as a power of 1/2. √a = a^1/2. This is basic algebra, not physics.

Incidentally, I'm *so* happy that @stlartsupply.bsky.social is my local art store.

Went out into Forest Park today to try to sketch some of the tornado damage. Photos really don't capture how deeply unsettling it is seeing the landscape go from basically normal to obliterated in the span of a couple of city blocks. Maybe art can do a little better. #STL #tornado #art

Found this in the street after today's #tornado. Had to have been carried at least a mile. #stl #stlwx

Just want to add to that in no way do I blame the security guards for any of this. They're doing the best they can with an annoying and thankless job. Please be nice to them. This is all on Metrolink, a series of utterly baffling decisions to the detriment of the public and the benefit of no one.

The new pope has a BS in mathematics from Villanova, which explains how he was so successful at becoming the largest cardinal.

Drinking a toast in memory of our friend Phoebe, who ran the wine shop down the street from us in #RogersPark. With a glass of wine on Amtrak, of course.

Having a great time at Milwaukee @play.pokemon.com regionals! I didn't do too well in the main event, but I'm having fun sketching people's plushies! (Thanks to folks from @girlpowertcg.bsky.social for some of the models!)
