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.

A photo of a large chalk drawing at the bottom of concrete steps. A pink lowercase pi appears inside a pie with yellow filling and an orange crust.

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.

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.

And this is one reason I stopped wearing jeans. It just isn't worth figuring out which size I am in the same brand and same style year to year.

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?

So do I, but that doesn't mean I can read a long literary novel between, say, September and November.

Anyhow! I adored Cloud Cuckoo Land by Anthony Doerr.

Any opinions on length? This is one of the ways my book club narrows down choices: shorter reads are for the academic year, longer reads are for the summer/winter breaks.

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.

Apparently while I was asleep, part of my brain came up with:

Textbooks are read
Analysis is pleasurable
Unless you bumble into
A set that's non-measurable.

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.

Roses are red
If uniform convergence is your quest
Try to bound all the terms
And use the Weierstrass M-test.

Roses are red
Violets are blue
I suspect that it's clear
I'm teaching Real Analysis 2.
