Fermented (live) sauerkraut or the liquid from it. There is published research about it. Also, yum!

Similarly to defining other interactions ("Should I apologize for stepping on your foot?") it might help to switch from communicative intents to communicative impacts.

Patterns 451-500 — Visual Patterns

We now officially have 500 visual patterns! 🎉

Christophe from France just shared SIX wonderful building-brick patterns he discovered while playing with his daughter. 💕

It's all disturbing in so many ways: the scale of burning up resources instead of solving for human needs and dreams. That can't last in the long run because the resources are not renewable, but economics acts faster than ecology. Even the current messed-up economics won't sustain that grift. Yay?

An AI Addendum Last month, I chose to strip away all the hubris around AI and ask one simple question, one that oddly no one had really bothered to ask; how much revenue is needed to justify the current level of cap...

What a fun Fermi problem to read! For a while now, I've been looking forward to the time when economics and thermodynamics cut down the big silly AI and we can finally enjoy the more sustainable, reasonable, and humane AI. This mathy saga is validating my feelings. 😆 pracap.com/an-ai-addend...

She also taught us to band together, to always show up for one another's presentations at conferences, and to arrange, ahead of time, for someone friendly to be around our talks. We could think of good questions ahead of time, that sort of thing. "Me and what army? This!" A buddy system.

My academic advisor (a mom of 4 and a hero of women in academia) often said that if it's a shark situation, one quick bop on the nose might stop it. Figuratively speaking. I saw her at that, too, for example, with a warning tone, a glare, and a pointed pause, "Let me finish!!!" when interrupted.

Today’s #mathober is polyhedron. Which is your favorite? Why?

I will start my sketches later- any suggestions or takes on the prompt are welcome. What Pacific Northwest bird should be next?

ChatGPT 5 successfully painting 5 pears.

That one did better, though I like 4o better for my flow. It keeps the context stable for a bit longer.

A screenshot from ChatGPT with the prompt "Paint 15 apples" and an array of 4x4 apples.

I tried again right now. I wonder why the backgrounds and arrays are so consistent. I started a new thread with this prompt at the top.

A sad result over at Mastodon, really. What could be changed in the mathematical community in order to get a different outcome?

Children playing with mathematical objects like hyperbolic saddles, polyhedra, and paper airplanes.

An idea: Start by sharing your research topic with a five-year-old.

Can we welcome children and their families? The obvious reason: we need the next generation of math. A deeper reason: young kids are amazing sources of math connections and creativity, since their thinking is very divergent.

AIs can deal with formal math represented in formulas (that is, the math language), though never 100% reliably. They are spectacularly bad at any transfer between representations, such as writing a realistic scenario that models a formula or creating an image with a given number of objects.

With constant oversight 👀, I use AI in teaching to:
- proofread;
- search the web (RIP Google) and look up "What do you call that thing...?" and other fuzzy searches; you can prompt AI to avoid sources suspected of AI contamination; 😂
- that's it!
Language models work okay for these language tasks.

Beaded Archimedean Solids made of colourful beads on a grey background.

Beaded Archimedean Solids!!!

I had lots of fun over the past two weeks making these for the pigeonholes at the TMiP conference.

[Each n-regular graph has an n-colouring and there's a pair of colours on each one which form a Hamiltonian cycle.]

"Natural Math," literally. This is a great autumn activity for all ages. Don't expect perfect symmetry like this if toddlers are involved, but they'll enjoy it and learn a lot! #iTeachMath

A viable level of embodiment for early mathematics? I can't wait! 👍 #iTeachMath #MathSky

"There's no sense in being precise when you don't even know what you're talking about." [attr. to John von Neumann, mathematician, physicist, computer scientist]

That empty crib is a nice suspense-building touch, but the scene needs more tentacles for a wider audience appeal. 🐙 🤖 😱

"Modultown" will be out soon and then it will all make sense! 👍

That lightning bug one would make such a wonderful mail box cover.
