If one wanted to, one could probably write a question about pursuit curves set in the "Weapons" universe

If you see this and think “augmented Tricsuit,” #YouMightBeAMathematician

It's worth a little more detail: Her teacher had them write a proof, then the next question said something like, "If you used more than 4 steps in the previous proof, could you write a proof using fewer steps than you did?" 😒 [1/4]

After receiving little more than groans and eye rolls when helping my 14yo daughter with her math homework over the years, I finally got it last night after talking her through a Geometry proof: "Why couldn't YOU be my math teacher?"

On of my geometry students just talked about the Angle Addition Prostitute and I think my day is over.

I'm just trying to write an email to my wife outlining our schedule for the next couple of weeks. It looks like I've got at least three different "checkers" telling me I'm doing it wrong. 😑

I asked ChatGPT a True/False question from Hammack's "Book of Proof," and it did something I hadn't seen it do before. It first said the statement was true, and then as it explained its "reasoning," it wound up convincing itself that the statement was false (which it is). #MathSky #iTeachMath

A certain polyhedron has 6 faces and 8 vertices. Must it have a hexagonal cross-section? #iTeachMath #math #WonderWithMe

Oooh, new mathematical quackery just dropped

Once every couple of weeks we get an email with the subject "PD Newsletter" making us aware of various PD opportunities available to us. But when I see it appear in my inbox, my first thought (if you could even call it that) is to respond, "PD Newsletter? What the f___ does THAT mean?" #iykyk

Consider a regular heptagon with side length 1 unit. Its diagonals have two distinct lengths. Prove that the sum of those two distinct lengths is equal to their product. #iTeachMath #MathSky

My Advanced Topics students are super into this whole "degrees of infinity" thing. They've spent most of two whole class periods wondering and brainstorming. I spent that time trying not to let my knowledge of "the answer" seep out too much in my attempts to help them prime their thinking.

My 14yo daughter asked me to check her work on a Geometry worksheet. It was some of the most boring and soulless drudgery I've seen. The "We sprinkled some random algebra into repetitive questions about the Angle Addition Postulate and the Segment Addition Postulate. Boom. Geometry" type.

TIL that the phrase "good doobie" came from Romper Room 😮

Beginner's luck? Connections Puzzle #837 🟨🟨🟨🟨 🟦🟦🟦🟦 🟩🟩🟩🟩 🟪🟪🟪🟪

Introduced Advanced Topics to 𝒫(ℝ²) today. Minds were appropriately blown. Including my own, when one student referred to the humans in the room as "elements of 𝒫(ℝ³)."

A student drew this portrait of me on her test today

Reminds me of the time my dad texted me "Just got shot" to let me know he'd just gotten his COVID shot 😑

Can't wait to get to this bit of Hammack's "Book of Proof" with Advanced Topics 🤯🤯🤯 #iTeachMath

Pretty wild that two-hit wonder The Escape Club’s two hits were “Wild Wild West” and “I’ll Be There.” Just… two completely different songs.

A colleague asked if she could decorate a room we both teach in. I said “Sure.” She made it clear I could veto anything she put up, but I was all, “Nah, whatever’s fine.” Until…

One minute I was prepping for classes. The next minute I found myself on the webpage of a Vermont falconer. I'm sure there was a linear path I followed to get from the former to the latter, but I'll be darned if I could tell you what it was. #ADHD

Any way I can school Canvas on how to properly vertically align its equations?

Soooooo if I were to remove a single star from an American flag, and THEN burn it, would I still get a year in jail? If so, how many stars and/or stripes would I have to remove before the answer would be “No”?

The entire 10-day forecast: Highs in the low 70s, dew points in the low 50s. I can’t remember ever having seen back-to-school weather this glorious before.

“But Officer, I was just trying to beat Waze’s ETA” probably won’t fly, huh

I had my 14yo daughter (M) and son (L) rate and “review” (if they so desired) a bunch of movies we’ve watched together

Plot twist: Turns out ALL of the disciplines and courses of study were "the humanities" all along

Astounding

I don't think insurance companies are eager to implement AI voice agents to "staff" their customer service lines, because they might wind up being inadvertently helpful

I can't believe I'm just figuring out now that the ASCII alphabets starting at A=65 and a=97 MAKES SENSE, because 65 = 01000001₂ 97 = 01100001₂ I've done a lot of (very simple) programming, and I've always had to look those numbers up because I could never remember them. 🤦

Your periodic reminder

🤔🤔🤔

Me: Hey Self, remember that stretch of a few weeks when we meditated for 10-15 minutes a day every day, and how it somewhat mollified your #ADHD symptoms, and how nice that felt? Me: Yeah. That was pretty cool. Me: Yeah. Me: *continues to never do it again* 😑😑😑

What in San Dimas is going on here

Another wondering-prompt I just gave myself: An infinite set of regular-pentagonal rooms, each connected to five others, one door on each side

How do I come up with "original" (as in, new-to-me) math problems? It always starts with wondering. Like: What if a set 𝑆 ∈ ℝ² had the property that if points A and B are in 𝑆, then so is the midpoint of segment AB? Then I just start wondering things about 𝑆. Curiosity is such a powerful engine.

Applies to many tasks, such as: - putting away groceries - folding and putting away clean laundry - cleaning the kitchen - cleaning pretty much any room in the house #ADHD

Square ABCD is to be folded once so that point A lies somewhere on segment BC, then unfolded, leaving a crease. That crease will divide the square into two pieces. What proportion of the square's area consists of points that are guaranteed to be on the same piece as A?

Here's 9 consecutive primes that end in a '1': 36539311 36539381 36539401 36539411 36539431 36539441 36539471 36539491 36539501 Are there arbitrarily long runs of consecutive primes that end in a '1'? #WonderWithMe #iTeachMath #MathSky #math #mathchat

Take the infinite sequence of primes, and reduce them all modulo some integer m>2. Are there runs of identical terms of arbitrary length in this new sequence? For example, is there a run of 100 consecutive primes that are all congruent to each other mod 67? My conjecture: 🤷‍♂️ Sure!

Rectangular piece of paper ABCD has a perimeter of 44 units. If you fold the rectangle once so that point A lands on the midpoint of BC, then the perimeter of the resulting polygon (considering only the exterior outline) is 39 units. How long is the crease? #iTeachMath #MathSky

don’t forget then beating yourself up for not being able to do something so simple #ADHD

Reached peak Gen X Dad this morning, driving my teenagers to day camp, blasting & jamming out to "Kyrie" by Mr. Mister, while said teenagers, resigned to their fate, sat silent and sullen in the back seat

Three math ed ideas that have stuck with me and guided me for years: Dan Meyer: If [math idea] is the aspirin, how do we create the headache? Francis Su #1: Whom do we allow to see the "secret menu" of math? Francis Su #2: Does your math class feel like domination, or freedom? (links below)

Is it possible to start with a polygon, fold it completely over a single crease, and have the new polygon that its outline forms have a perimeter greater than its original perimeter? #WonderWithMe #iTeachMath
