When I was a postdoc at Dartmouth, a librarian told us that he could arrange special collections visits for any class. "Calculus?" This was apparently a new question. He rocked it. Einstein's work (w/ Kemeny's corrections) back to old yearbooks back to a 1482 Euclid. Thank you, Jay! #MathSky

Hey #MathSky, can I get some applause? I just started my JMM slides file and remembered to name it jmm_2026.tex.

Why decline all these chances to defend feminism? Because to participate would be accepting the premise that our rights and humanity are up for debate in the first place. Once you’ve conceded that it’s reasonable to ask whether women’s equality was a mistake, you’ve already lost.

TOMORROW IS THE WINTER SOLSTICE AND Y'ALL KNOW WHAT THAT MEANS. It is time for the women (defined broadly) to hunt the Year King through the woods and tear him apart with their bare hands!

I walked through our art building on the way back from today's final, and my favorite class project is on display. The students are given the endpoint objects and have to sculpt them and three intermediate forms.

We've decided to solve the problem by changing the website: Women in Logic (WiL) Workshop 2026: womeninlogic.org/workshops/20...

36 years ago today, 14 women, most of whom were studying engineering, were killed by an anti-feminist gun man at École Polytechnique in Montreal. I was a young graduate student studying physics at the time and I will never forget. #MontrealMassacre #NeverForget 🧪 👩‍🔬 ⚛️ 🎢 #AcademicSky 🇨🇦

Dear My University, Thank you for suggesting that I should consider how to "choose [my] impact on Giving Tuesday." I am choosing to grade two classes' worth of quizzes tonight as well as a lot of reassessments. Oh, that isn't what you had in mind? Huh. ~Me

Happy December! Here's a little something about shapes: mathvoices.ams.org/featurecolum...
