Armies wear uniforms for a reason. And not just because it makes the laundry easier. I am reminded of certain lilac blossoms on a certain Glorious 25th of May. How do you tell your comrades from your potential murderers? A carrot, a leek, a lilac sprig, a red knitted hat, a frog costume. Duh.

"We would have lost so much if we'd driven him away" is the justification. But we lost all those girls. We lost the women they would have become. We lost the work they would have done. Why was his future work so much more valuable than theirs?

#MathSky Important: 11:59 p.m. *Eastern time* on February 1!

First day of classes in person! It's good when 0) about a third of your 8:00 calc 1 class actively participates without over-the-top encouragement and 1) 7/8 of your real analysis 2 class sticks around to talk with each other after you finish gathering your things and erasing the board, right?

Please stop saying F*%# 🧊. We love 🧊 and ❄️. Instead, use more respectful language to relay your message, such as: “f%#^ those rascist, fascist, feeble minded, bootlicking f%ks who keep killing people and disappearing children.” On behalf of the land that sustains us, the more specific the better

How do we assign sizes to subsets of the natural numbers (ℕ)? Sylvia Wenmackers compares the answers given by six formalisms to gain a better understanding of the trade-offs that arise when dealing with such a vexing problem in mathematics👇 riviste.fupress.net/index.php/jp... #philsci #HPS #philmath

Lovely thread! I always chat with Girl Scouts when I buy cookies from them, and these are some great pointers. And if I buy from Brownies in person, I try to make sure they have to make change for me so we can work with numbers a bit. 😉

#MathSky It is now only 2 weeks until the AWM/MfA Essay Contest deadline! If a student knows someone with a gender that's underrepresented in a mathematical career who's willing to do an interview with them in the coming week, they should enter! Categories: Grades 6-8, Grades 9-12, & Undergraduate.

I buy my cookies from these kids every year -- and you can, too, no matter where you are in the US!

Happy #WorldLogicDay! Thanks to the folks at @swanseauni.bsky.social for welcoming us virtually to the Robert Recorde room -- John Tucker's talk was a great start to my day.

🚨CALL FOR PAPERS🚨 Women in Logic workshop July 24-25, 2026 Abstracts should be written in English (max 2 pages excluding references), and prepared using the Easychair style (easychair.org/publications...), and uploaded here: submissions.floc26.org/wil/paper/new by May 5, 2026.

So today seems like a good day to share my Scott Adams story. A couple of decades ago, I was writing my dissertation on algorithmic randomness. There was a Dilbert cartoon with a troll acting as a random number generator that I thought would be fun to include: 1/3

We are so excited this is happening! Ask me any questions, #TCSSky #MathSky! Also, we are looking for a couple more project leaders, so if you want to know more about what that involves, please get in touch.

AWM and 11 other mathematical societies participated in #MathSciOnTheHill on January 8, with 280 mathematicians from 47 states visiting Capitol Hill to advocate for federal support for the mathematical sciences! Thank you to everyone who participated! #AWM #Mathematics

I am so glad to have taken part in this!

Well, Hilton Honors membership cancelled. I went with "I am a woman who often travels alone, and if you let these agents stay in your hotels, I am not safe in your hotels."

Advances in Modal Logic Amsterdam, June 29 - July 3 events.illc.uva.nl/aiml2026/ Invited Speakers: Aybüke Özgün, Sara L. Uckelman, et al. Abstracts due: 20 Feb 2026

Reading "Blueprints" by Marcus du Sautoy, and while I am not a fan so far this did jump out at me: "Mathematics is far from being just a list of all the true statements we can discover about numbers. Mathematicians are storytellers [...] Not every story that it’s possible to tell is worth telling."

#MathSky It is now 3 weeks until the AWM/MfA Essay Contest deadline! Students can still find someone in a math career whose gender is underrepresented in math, interview them, and write an essay based on that interview! See below for contest rules:

#mathart #mathknitting #JMM2026 This year, the math art exhibition at the Joint Mathematics Meetings invited me to be a featured artist, giving me the chance to assemble this mini-retrospective of my knitted and beaded work. Links to the catalog entries are in the following posts. 🧶 #knitsky ☺️

We are #hiring! We are looking for a tenure-track Assistant Professor of Microbiology to join our Department in Fall 2026. Please share with your colleagues, mentees and friends! Deadline is January 15! hofstra.peopleadmin.com/postings/6543

At the Capitol for #MathSciOnTheHill!

#MathSky #JMM2026 It is 4 weeks until Feb. 1, better known as the AWM/MfA Essay Contest deadline! That's plenty of time for a student to interview a mathematician whose gender is underrepresented in math and write an essay about them. Contest rules below:

Starting out #JMM2026 with Maisha Moses from the YPP!

I hope you continue to be the thing that you are and want to be. I am a bear.

ACADEMIC ACHIEVEMENT UNLOCKED 🎓 I finished my master’s in strategic communication and wrapped a capstone on researchers experiences moving from Twitter/X to Bluesky. Thanks to all of #AcademicSky who participated. I would have loved more interviews. But even with a small sample, I learned a lot. 🧵

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

🙂‍↔️🫸 Calculus II exam 😎👉 Series finale

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...

Writing holiday cards while watching my real analysis students take their final. Comfort and joy to all of us in this room! #AcademicSky

Hofstra Biology is hiring (again!): a tenure-track position in microbiology. Come join our collegial and rapidly growing dept. Small class sizes, hands on learning and research, manageable teaching loads and real startup. Please reach out for more info!
