Help, #MathSky community: Trying to get a handle on how different techniques of integration are covered at different types of institutions. Take 2 minutes (I swear) and fill out this quick survey: forms.gle/hk9nfSwwme82...

$Different techniques of integration, including integration by parts, trig substitution, trig integrals, and partial fractions.$

If you haven't played with pretext.plus in a while, we just spruced up the editor. It's looking pretty good even on mobile!

Screenshot of my intro to Topology book on pretext plus taken on an Android device. Design elements akin to Google Docs in the menu bar and VS Code for a sidebar hopefully provide an improved user experience.

It's come along enough to share... An Algebra Game (the start thereof, at least), like the Natural Number Game! adam.math.hhu.de#/g/CRGibbons... Play it, critique it, join the development team (which is... just me)! It's meant to go along with a "rings first" semester of abstract algebra

Damn, my kid is old enough to be doing math that I have opinions about (teacher says multiplication is groups×members and not members×groups and also rows are groups but columns are not) 🤬

The Emma Frost x Miss Piggy comic has hit the internet and it's so, so, so much more magnificent than I ever could have hoped for

Emma Frost: "Emma Frost, darling. I'm a telepath. May I read your mind to ascertain if you're telling the truth?"

Miss Piggy: "But of course, darling I am an open book, a tell-all memoir."

Emma Frost telepathically witnessing the entirety of Miss Piggy's life.

Wolverine: "Frost? She legit?"
Emma Frost: "She's..She's... She's everything. And I would die for her."

#MathSky #MTBoS FYI: I am working on my _Abstract Algebra, Actively!_ manuscript and testing out the final rearrangement of material with my current students this semester. I thought I'd share the course (as I short-hand it for the semester) as a prelude to the book: pub.pretext.plus/o/1e65c5f6-2...

Lol they burned through almost double the budget of the American Institute of Mathematics's five year award on this. www.nsf.gov/awardsearch/... The more you think about it, the more of an L this is for "AI Solves Math": call me back when you compare with giving humans the same amount of resources.

Teaching topology in 2026. 🚀

A screenshot of Lurch.Clontz.org. A partial proof of the fact that the discrete topology is a topology is partially validated by Ken Monk's Lurch javascript app (but saving to the cloud on this very new, almost certainly bugged web app I've put up).

I don't know what makes me a better dad: this, or the fact that her favorite game to play in the car is to take my "Undertale/Deltarune Bangers" Spotify playlist and see who can "name that tune" quicker. (yes Petal Dance / Aqua are her favorite)

😍 8yo came home today shared the "math game" she made up: pick x,y, then compute x+y,abs(x-y), and repeat. So obviously I demonstrated writing a computer program to implement her game, and demonstrated the Collatz conjecture. Her reaction: sing "LAAA" as if a light had shone down from heaven. 😆
