A reminder that LLMs are fundamentally the wrong class of model for many applications. Often, a better choice is a simple database, an FAQ, or just good notes. If you want interactive personalized learning, good luck to you... just don't use an LLM as a computation engine.

Last day with precalc. Yearbook signatures, puzzles, math games from Ben Orlin, and fractal tiles portraits of me.

Hey everyone, nbd, but I've been exclusively invited by NCTM. Bet you're jealous.

I was devastated to not find any of Vi Hart's videos on youtube. I'm sure because of harassment, what a terrible place youtube can be. BUT found their Vimeo channel: vimeo.com/vihart Phew. BTW, share these videos with your students, they haven't seen any of them and they are truly wonderful.

I'm concerned that chatGPT is spitting out incorrect information. Who can I sue?

Because of AI, is homework dead? For most math classes? (there is discussion of this on Mr Barton's most recent podcast www.mrbartonmaths.com/blog?ppplaye...)

And here it is: The #MathArt starter pack: go.bsky.app/CiKwTsg. Do you have a person from the #MathArt community here on Bsky who is missing? Please let me know, I'll gladly add them.

Wow: after 15 years, YouTube has taken down the original 'Rick Roll' video due to a "licensing issue," likely due to the acquisition of Astley's record lable. The metadata remains, but if you click through it goes to 'video not found': www.youtube.com/watch?v=dQw4...

Just to get some people fired up today (in case you're one of the ten thousand people who are hearing this for the first time xkcd.com/1053/) 5! = 1*2*3*4*5 = 120 5!! =/= 120! 5!! = 1*3*5 = 15. so 5! > 5!!. Sad.
