Plato associated the tetrahedron with fire. I made it ice. 🧊🔥

The simplest Platonic solid: just 4 triangles, each one's corners chasing each other inward, then letting go.

A quiet one for Sunday.

I guess that's the question -- should I save it up for when it's wood stove season again, or just pitch it? (And do we accumulate more junk mail / printouts than the wood stove can eat on its own? maybe.)

Oh, yeah, I wasn’t going to burn the campaign mailers (although it’s tempting). I meant more like paper stuff.

@leahwrenn.bsky.socialOct 11, 2026, 7:26 PM

Is it better to burn my junk mail or to put it in the landfill? Assume that I do not have access to effective paper recycling and that I don't burn when we're under a burn ban.

It looks like the AK Judicial Council recommends a Yes vote for all the judges in my district, the 4th judicial district, but they recommended a NO vote for two of the judges (Kelly Lawson and Martin Fallon) in the 3rd Judicial District (!!). Check your voter's pamphlet, y'all!

I put Dynata and Clear Insights on my personal "do not respond to them" list after the fourth or fifth survey where they were like "It's been reported that Mary Peltola eats babies. Are you more likely or less likely to vote for her? Is that strongly more likely?"

I just don’t get how ANY polls are possibly reliable in Alaska right now, because no one’s answering their phone. Or if they are, they’re not answering surveys. Because they’re mostly “surveys”.

@leahwrenn.bsky.socialOct 11, 2026, 5:27 PM

Ha, we’re getting so many sketchy “public opinion firms” calling. I want to answer the legit ones, so I still answer my phone, but mostly they’re sketch. This one, first he said “survey of Alaska”, then that he had a number I could call, but when said I was going to look it up he hung up.

An alternative take is that it has become so normalised that, when contrasted with what the big AI companies are doing, people think that their use isn’t something that really counts. You don’t acknowledge something that’s mundane, only something unusual.

This is the last week to submit your art for the exhibition to be held as part of the upcoming Joint Mathematics Meetings. Take advantage of this opportunity to share your work with over 5000 attendees this January in Chicago. You’ll need to submit by the 15th at gallery.bridgesmathart.org.

The mushrooms are up here in Southeast Alaska. Going out and looking for them and taking pictures is sooo fun and a great way to get away from the news.

I see the Wonderful pistachios people are leaning into using the robot.

Was talking w some colleagues the other day and we came to the conclusion that, at this point, AI-generated Lean code adds almost zero to our confidence that the stated results are correct and correctly proved. (We already knew it added zero to our understanding.)

Trying a different color palette (palette 76 from the book “A Dictionary of Color Combinations Vol 2”) on my favorite decomposition of the infinite knight’s graph into four 2-factors.

Beautiful night from Maine looking north on this live cam, I mean check out the big dipper here--stunning! Unfortunately, the auroral arc has only retreated here over the past couple hours as Bz has been slammed north.

I’m so aggravated by these students who are…communicating…that there’s a (23_4) configuration (great!) but were not clear about/didn’t mention their AI use. I have to infer it because there’s some lean code in one of the GitHubs and the other result is on GitHub, apparently due to a HS student.
