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 hereβs the link if you want to review it π www.desmos.com/calculator/3...

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?! π 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).

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

Building sage from scratch feels like arcane wizardry and I'm not here for it. I just wanted snappy and kbmag to be working together and here I am
Update: (all public info), he was a freshman at my school, now he's somewhere else. At least UCM was mentionable π
