Ferrothorn for Vinelasher Kudzu!

But also don't get me started on "attendance points" or tracking attendance in the first place. Ugh

As someone who was forced to use Active Learning in grad school, it was hell for me too. Too many social cues to follow, too many unspoken/unwritten norms to break down. Now I'm having to learn how to lecture properly, since I was never mentored on how to do so properly during my training.

Exotic R^4s are my Roman Empire

Maine is the Ohio of New England, and I cannot be convinced otherwise.

three arrows down and to the left inside a circle, but the arrows are decorated as a weak equivalence, cofibration, and fibration

Homotopy theorists against fascism.

It's literally "just" calculus. Force isn't constant so the work isn't directly proportional to the weight being lifted.

Thank you!

Just submitted my first solo paper to the arXiv!

I had a teacher once say "Prepare your child for the road, not the road for your child." And its stuck with me for 20 years.

It's even worse when the invariant turns out to be equivalent to just some pile of linear algebra applied to some equivariant or twisted version of a Seifert form

I feel so seen

learning the material is my favorite cheating method

A lot of people have asked me how I created this Gastly using graphs, so here’s the link if you want to review it 🔗 www.desmos.com/calculator/3...

In the Godot Shaders Bible I explain how to transform all these functions into GDSL code ✨ jettelly.com/store/the-go...

Euclid is known as the "father of geometry" because he got a triangle pregnant

Friends of Stats: The U. of Nebraska-Lincoln Department of Statistics needs your help. The university's Chancellor submitted a FINAL proposal today for budget cuts (budgetprocess.unl.edu/final-budget...) that eliminates the department. 1/ #LNK #Nebraska #Huskers @amstatnews.bsky.social

Reminds me of a positive cone, so perhaps something along those lines?

Major website upgrade live! Lots of pretty things now. (And much less red!)

Jamovi for analysis, LibreOffice for organizing.

Recency bias. It's objectively not the worst set, but because it's a bad set that happened recently, people remember it.

Bridge trisections?! 👀 Or just cap diagrams?

We used a fork of AC at Nebraska and I LOVED it. OpenStax is a good supplement for those students who need a bit more structure in the text (or who need extra practice problems).

“I asked ChatGPT,” well I asked your mom and she said you’ve always been a disappointment

Given that the film came out in 1998, I'd say that Cillian modeled himself after the Antz

No, but there is one called Antz

I'm personally a fan of Pantz
