What fresh hell is this

My 15yo son manages to get pizza sauce on every new article of clothing the first time he wears it. Even if we haven't eaten pizza. Somehow he still makes it happen.

Going to try to discover some log rules in Alg II Honors today #iTeachMath

My kids introduced me to this and I will never forgive them for it

Kitchen hack: Use a poker chip set—heavy, but low center of gravity—to press tofu

A "making of" my #mathart post from yesterday

🙄

Just checking in on my Janus account. This is what I see (minus personal specifics): the Contrarian fund living up to its name

One minute you're puzzling over a simple probability question, the next minute you're unironically typing out an expression that looks like this

Hyperbolic surfaces spotted at the Andrew Gn exhibit at the Peabody Essex Museum

Okay this one is a beast #math #mathchat #maths #mathschat #probability #iTeachMath #MathSky

Here's a fun Geometry quickie: A particular polygon has only two distinct interior angle measures: 165° and 166°. How many sides does it have? #iTeachMath

Me figuring out how to make Canvas API calls from Google Sheets

I vibe-coded a web app that allows you to walk around on the surface of a gyroid. It's just as disorienting as you'd expect. velvety-arithmetic-0a8353.netlify.app

It's kind of a running gag in our house about how boring my Facebook posts were before we had kids, but this one kind of takes the cake

MAA MathFest is in Boston this year! I've never been, and always wanted to. A significantly reduced registration rate for K-12 teachers? And I might be able to bring one of my kids as a "guest"? This may be my opportunity! Anyone else I know planning on attending? maa.org/event/mathfe...

Three words/phrases you never want to hear from your plumber when you're describing your problem over the phone: "absolute nightmare," "worst-case scenario," and "jackhammer"

One superpower #math gives me is the ability to picture an interesting object in my head, spark up #Mathematica, and within a few minutes figure out how to make it "real." It's intoxicating! (code in ALT)

Just arrived 😍😍😍

After a few weeks of repeated discussion and revision, here is where the Axiom (& Theorem) List for ℤ that my Advanced Topics class has been generating from scratch—with some prodding and guardrails provided by me—currently stands. (Proofs of the Theorems are located elsewhere.) #MathSky #iTeachMath

Why are the emails that require the meagerest of replies—"All set!" "Thank you!" "Great! See you then!"—sometimes the hardest to get myself to write?!? Makes no sense. Stupid #ADHD brain...

Student 1: I don’t get this. Student 2: Oh! Let me show you a trick my tutor showed me. Me: 😑🤐 S1: *shows S2* S2: OMG, that is so EASY! Mr. Enlow, why didn’t you teach us this?!? Me: 😑😑😑😑😑

Please stop teaching the "X method" for factoring. And please de-stigmatize "guess-check-revise." Yes, it's slower. But it yields SO much more actual learning and understanding than blindly following an algorithm does. #iTeachMath #MathSky

🤔🤔🤔

An update to my ring project. This was not easy to achieve! #mathart #3DPrinting #Mathematica #MeshLab

Now that Shapeways has apparently risen from its ashes (with the help of @thangs3d.bsky.social ), I'm trying to design an interesting ring. Copies of this one nestle inside each other nicely. #3DPrinting #Mathematica #MeshLab

Finally got around to this. I’ve only read the Introduction so far, but it is so good. I want to force everyone in the world to read it (and decide for themselves whether to continue). I’ll have to settle for “everyone in my household.” 😁 @jsellenberg.bsky.social

Cool! The circles in an Apollonian Gasket can all have an equation of the form (n|x|-a)² + (n|y|-b)² = 1, where n is a positive integer, and a & b are non-negative integers < n. www.desmos.com/calculator/6... #MathSky #iTeachMath

Three mutually tangent spheres with radii 1, 2, and 3 units are centered, respectively, at (0,0,0), (3,0,0), and (0,4,0). There are only two planes tangent to all three spheres, and they intersect in a line in the x-y plane. Find an equation (in x&y) for that line. #MathSky #iTeachMath #math #maths

Last day of classes. Second-to-last class of the day. Algebra II Honors. A student says, "Why did I bother coming to school today? All I've done, in multiple classes, is watch 'Elf'!" 🤨 (Said student was somehow NOT happy that we were "actually doing math" today. 🤷‍♂️) #iTeachMath

Yep! Thanks to @joeldavidhamkins.bsky.social www.infinitelymore.xyz/p/monkey-mad...

Given our ability to program clouds of drones, it can't be too long before we get self-rearranging desks in our classrooms Pre-program a few arrangements, then just push a button and wait 60 seconds, and boom

Fibonacci Voronoi-ing in #MeshLab (with assistance from #Mathematica, of course)

For today’s Advanced Topics test I wrote my own @joeldavidhamkins.bsky.social -style question 😁 #iteachmath #MathSky

"I’m honored, obviously, to get to be one of the people that gets to choose which movies get made, and which ones don’t. That’s huge. And I got into all this because I love movies! But… now I have this fear… that my job is to ruin them." -- Matt Remick (Seth Rogen), "The Studio" Man do I feel that.

I got tired of my Alg II Honors students asking me when their tests would be graded, so I created a Google Sheet that simulates a "Progress Bar." And I don't have to update it manually; I tied it to a separate Sheet where I log their scores on individual questions, so it updates as I fill it out 🤓

Get you a Department Head who recognizes when a meeting can be an email and cancels the former accordingly 🥰

My second OEIS sequence has been approved! oeis.org/A390274

Y'all, I made an example problem in Geometry class this morning that had a 67° angle in it, and the most I got was smirks. I think we're finally on the other side of it.

TFW you search for an answer to a very niche technical question and your primary result is someone else asking the same question on some message board, ten years ago, with zero responses

The latest iteration of this Fibonacci spiral #mathgif uses closed BSplineCurves instead of polygons. There is this odd behavior I'm observing away from the center that reminds me of soap bubbles combining. I can't decide how I feel about it. #Mathematica #mathart

“It took me four years to paint like Raphael, but a lifetime to paint like a child.” — Pablo Picasso I've seen this quote before, but it's hitting me particularly hard today. There's something here relevant to math education (and I bet @mathgarden.bsky.social has already written about it 😉).

Just a little coding diversion before doing some schoolwork #mathart #Mathematica

After getting the mail, my wife calls to me from another room, “Your Victoria’s Secret catalog came.” “Huh?!?” Baffled, I go and find her. At which point she hands me the L. L. Bean Holiday Catalog. It’s good to be gotten.

Not today, Satan

Every time I reflexively hit ⌘S to save my work in a Google Doc or Google Sheet, I picture the Google gods somewhere chuckling to themselves and enjoying my preciousness

I have a conjecture!

*starts writing a Trimester-I comment for an Advanced Topics student* *talks about the great work this student did on an open problem* *starts wondering things about the problem* *sparks up #Mathematica* *an hour passes with no writing taking place* 😑😑😑 #iTeachMath #ADHD #MathSky
