What this thread doesn't mention: the English language contains the numerals lakh and crore for a significant percentage of its native speakers. en.wikipedia.org/wiki/Indian_...

Hot take: The English language is not base ten. It's base thousand. Sure, we write numbers using the Hindu-Arabic digits 0 through 9, but the way our language is structured groups numbers in powers of a thousand. If anything, we're sub-base ten. (1/5)

Holding class discussions on readings is HARD. English teachers, how do y'all even do it? I'm honestly struggling. 😕

Student: “Babylonian numerals are kinda confusing… 60 is such a weird and unintuitive base.” Me: “Yeah I know right? Oh hey by the way, what time does this class end?” Student: “At 11:30.” Me: *waits* Multiple students: “…OHHHHHHHHHH” #MathSky

Today's lesson in COR 314! Students learned how to count in Iñupiaq and write numbers using the Kaktovik numerals (as well as convert between base ten and base twenty). 🧮 Lots of discussion about how the way we're used to thinking isn't the only way to do things! 🙂

Anyone else moving to more in-class assessments this semester due to AI concerns and not particularly thrilled about it, but not feeling like they have much of another choice? 😕

Me: After I graduate I’m gonna write my own textbook! And start a new video series! And program a game! And go to the gym! And cook more often! And… Also me: I dun wanna get up it’s not noon yet

Anyone have ideas for games (especially combinatorial ones) that inherently involve taxicab geometry? Not just games that happen to take place on a square lattice but where taxicab distance is actually an important part of playing the game?

Who’s going to be at #MAAthfest next week? Let’s meet up!

My dissertation is officially uploaded, so I finally feel like I can say I have my PhD! 🥳 scholarworks.gsu.edu/entities/pub... It's been exhausting going to school while working full time at Oglethorpe... But looking forward to doing my own projects again, like video-making and textbook-writing!

Happy #PiDay! To celebrate, here's my favorite representation of π: as a position in the combinatorial game of Stacks.

Something seems off about the Euler characteristic of this hush puppy.

Apparently this is now what I do for fun when I need a break from work. 😂

Happy (20 + 25)² :D

This year's deviled eggs for #NewYearsEve! Left: Garlic deviled eggs (using toum!) Right: Ramen deviled eggs (made like onsen eggs but hard boiled)

NAILED IT

About to take my final for Abstract Algebra (group and field theory). If this goes well it will be the *last* final I ever have to take. LET’S GO! 😎

Presented without comment: The Thermograph of "oof".

Optimist: The cup is half full. Pessimist: The cup is half empty. Combinatorial game theorist: The cup is a win for Left, because she can take it to the zero cup. If Right moves, he will take it to the one cup.

Here's an entry for #GoodLunch!

Question for #MathSky! Does anyone teach a Business Calculus course? If so, do you have any good projects? I'm slated to teach it next semester and would love to do at least one project. We do differential, some integral, and some multivariable (partial derivatives & Lagrange multipliers.)

Forget Myers-Briggs. Forget star signs. I want to know where you stand on the value of 0⁰, the continuity of 1/x, and whether 0 ∈ ℕ. youtu.be/rBz5k2T7p4A?...

Thanks to everyone who provided graphs! Added a few new ones I really liked, and they led to great discussion. A lot of students were surprised that these graphs actually made it to production of anything ... I told them that's why math teachers will always have a job. 😂

Hey #MathSky — what are your favorite misleading graphs? I’m teaching my lesson on bad statistics tomorrow. I’ve got a bunch of graphs I use consistently, but I’d love some new ones for my collection.

tfw you're really bad at a game but you refuse to give up

#TodayInMaths we showed how Bayes' Theorem is the math(s) behind both poker bluffing and medical tests! We also talked about the implications of false positives AND false negatives, the importance of non-stigmatizing language, and further application to law. Next week — Texas hold'em!

So like ... can we start using #TodayInMath or are we required to use the British spelling

2012: “join Twitter? just so I can learn what some moron had for lunch?” 2024: “I’ve joined Bluesky to follow the ‘Good Lunch’ Feed. People post their lunch and others reply good lunch when it’s a good lunch”

I have some interesting updates on the SOMAP if you are interested in Soma Cube stuff.

I need to start interacting here more regularly, but I’m terrible at coming up with what to post… …so until I come up with something better, I’m going to start occasionally posting some of the bizarre and lovable diagrams from Winning Ways. Who’s game?

Math teachers — what do you do when students won't take advantage of opportunities to revise their work? I've given detailed feedback and repeatedly tried to make the message extremely explicit that they get *full credit*, but it's disheartening that it seems to go in one ear and out the other. 😕

Today's discussion for COR 314: The modern implications of probability and statistics, in particular focusing on algorithmic bias and AI. youtu.be/gV0_raKR2UQ?... Anyone else have other suggested readings or videos on this topic for future semesters? Always looking to build a bank of articles.

Another really good one! So glad to see familiar faces I used to follow on Twitter.

Mega useful set of accounts to follow for anyone new to BlueSky and wants to connect with mathematicians!

Do any of y'all use live polling software in the classroom? I've been using Mentimeter this semester for Statistics, and it's been okay, but I feel like there has to be something better. Preferably something with good PowerPoint integration (and without breaking the bank). Any recommendations?

Algebraists don't say "I love you", they say "Gal(K:F) ≅ Gal(E:F) / Gal(E:K)", and I just think that's really beautiful

Opening BlueSky and seeing math talk and math folks has been so refreshing. 🐵

I’m doing the lords work by reposting math memes on bluesky while we wait for everyone in math twitter to migrate to bluesky

"Combinatorial Game Theory" is insane because it appears to be one of the most legitimately dangerous drugs with the potential to gigafry your brain but is exclusively taken by math nerds who unironically want to "just have fun with numbers" and basically get oneshotted by it

Hey everyone, I'm still here. I've been busy as hell with my PhD program (it's the last year!), and I haven't had the energy to do much on social media. But I think this election is the impetus I've needed to finally make the jump to Bluesky for real. I may not be active yet, but I hope to be soon.

Just taught an entire 105-minute online Statistics lesson like this. 😂 The mouth even moves. Best impulse buy at Spirit Halloween ever. 🐺

A really handy use case for #ChatGPT as an educator: coming up with problem scenarios. I am *terribly* slow and uncreative at coming up with these, so ChatGPT has been an absolute godsend when it comes to generating practice problems for my Elementary Statistics class.

This is a reminder that a tightly timed, pencil-and-paper, individual exam with no resources is in NO WAY what mathematics is actually like.
