Quarterly fundraising reporting is approaching. If you'd like Tom Suozzi to have a bad day, please consider chipping in $25 (or whatever you can afford!) to my campaign. A few reasons he deserves to have a bad day, or: Why I decided to stop writing angry emails and primary Tom Suozzi. 🧵

Sandra Wong, the great granddaughter of Wong Kim Ark, is preparing to march at the #NoKings Rally in San Francisco. Today is the 128th Anniversary of the SCOTUS decision affirming birthright citizenship.

Today is the 128th anniversary of the Supreme Court’s decision on birthright citizenship in U.S. v. Wong Ark Kim.

Tomorrow I will be at the No Kings event in Port Washington, NY. Hope to see some of you there! If you'd like to help collect signatures to make sure I'm on the ballot in June, I will be near the LIRR stop around 11, and will be in the area for a few hours after the event. #NoKings #PrimarySuozzi

We're reminding President Trump what it means to be born in the U.S.A. We're honored that the one and only Bruce Springsteen trusted us with use of his iconic anthem ahead of our landmark Supreme Court case, where we’re challenging President Trump’s attempt to overturn birthright citizenship.

Hate Congress? Invest in a new one! I am running against Tom Suozzi (D(?)-NY), who continues to vote for laws that accelerate our descent into fascism. I, on the other hand, dislike fascism and want you to have nice things. www.votewelch.com

Yesterday's Pi Week math club celebration: playing "Math or Mural?" while eating pizza and pie. Today's Pi Week math club celebration: tabling in the student center and giving out free pie while doing a Buffon's Needle demo and a gravity well demo. Our students are pretty great.

So a single day for pi isn't enough for my students. Yesterday they kicked off Pi Week with the ritual chalking of the quad with the digits of pi and liquid nitrogen ice cream (physics club collab). 😊

Hey #MathSky, did you know that Henri Lebesgue's father was a typesetter? Support this Lego idea for Lebesgue!

This #InternationalWomensDay, consider supporting the woman challenging @tomsuozzi.bsky.social (me). If elected, I will be the first woman to represent this district, and one of the very few mothers of young children in Congress. And unlike Tom, I support *all* women, including Trans women.

Happy International Women's Day to all the wonderful Maths women - cis and trans - here on Bluesky 😀 #MathsToday

Announcement: the Metro NY section of the MAA will be hosting its annual meeting at St. Thomas Aquinas College on 5/2! Abstract deadline 3/30, early reg 4/10. STAC is close to the NJ and Seaway sections, and we welcome our neighbors. We'll have shuttles from Metro North/NJ Transit. #MathSky

Today is St David’s Day: patron saint of Wales, of course, but also of vegetarians and poets. He was reputed to have helped introduce bees to Ireland. He is famously quoted as saying “Gwnewch y pethau bychain”, meaning “Do the little things”. Small changes and good choices matter, especially now.

I was a lot happier way back when every single day didn't sound like a new verse of "We Didn't Start The Fire"...

Dear My University Again, How nice; our Day of Giving is today. You say "if you’ve already given, thank you." I taught calculus for 2 hours straight starting at 8:00 a.m., gave a talk at a nearby school with your name on the title slide, & am about to work on a grant app. So: You're welcome. ~Me

So much this.

Let's try this again 👋 Hi Bluesky - I'm Massachusetts' Attorney General. You might know me from suing President Trump nearly 50 times, beating Uber and Lyft in court, or being the first woman of color elected to statewide office in MA. I officially left X today - help me find my MA people?

This is a great interview.

In 1942, over 125,000 people of Japanese ancestry were unjustly incarcerated in America's concentration camps and deprived of their civil rights and due process. Sadly, there is an absolute parallel between what happened then and what’s happening today to immigrant communities throughout the nation.

TIL that in Old English the goose/geese tooth/teeth foot/feet alternation for plural nouns also applied to "book", so singular boc became plural bec! I am charmed. Bring back beek!

You didn't react when there were proportionally less women on conferences, papers, panels, awards, media appearances and senior positions. Didn't use your elevated societal position to chase after misconduct allegations or hold iffy colleague accountable. For decades.

"I have questions about this interstellar travel form," the human said. "What should I put at 'Rose'?" "The star system you are traveling from," xFfy said. "I see. And at 'Violet'?" "The one you're traveling to." "Ah. Who translated this form?" "Our best poets, well versed in human poetry."

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?

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)?

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. 😉
