The largest nurses' union is calling for the abolition of ICE and pledges to work to vote out any official who votes to fund them.
We're horrified & outraged: Immigration agents have once again committed cold-blooded murder of a public observer who posed no threat to them.
This time, they've executed a fellow nurse, Alex Pretti. We demand justice and accountability. Abolish ICE, now! https://bit.ly/4big77u

I have no patience for the people that are above it all and have the mental clarity to comment on some meta aspect or big picture as if the grief of the daily happenings cannot impact them. They are simply bankrupt of the soul.

If you are heading into the weekend and want to think about cool things, try these series questions! (They are not novel, so you may have seen them already, sorry!)
I wrote about two of my favorite infinite series problems to give to students. They're fun to do and have some cool things to think about and that's become increasingly important to me.

Thread 2:
A way to see a stochastic differential equation is the equation below representing how X evolves in time. dW is a "stochastic increment" -- it is introducing "randomness". But a LOT changes because of that, and it is the reason the below representation is not actually a good one! (1/n)

Working on writing up a lab book/project for a project-based stats class. Anyone have good (real, kind of clean, large) data sets? It's for business majors, so it's good if it's kind of based in that area. Needs to be robust enough for students to be able to propose different research questions.

What would you all want to learn about tomorrow in a math thread? Oja’s Rule (lot of linear algebra/basic dynamical systems, I just learned a proof abt it in a class I’d go through) or “What is a Stochastic Differential Equation”?

When you say "every day carry", you're talking about a metal credit card case, a flashlight, and a cool knife. I'm talking about a rOtring 600, Expo markers, and Propranolol. We are not the same. 😤

Oooh right, the fascists just don't know about the right to record, yah, that makes sense, once they know about this we're good. And the reason that they are embodying violent racism and homophobia of the state is because they haven't been properly trained to de-escalate, right.

Other aspects:

-training all law officers and agents, on Americans’ right to record any interactions.

Missing from the library vs buying discourse is that borrowing from the library and pirating online do not belong in the same category for a whole host of reasons. Authors are saying "I love that people can access my book and read it" and that doesn't mean "please steal it from me"

Had to pause in the middle of this while the semester started but I finished this today and it's incredible. Lots of really great payoffs and a fun perspective on Terraforming as well as...say, sentience and self. As expected with an @aptshadow.bsky.social book, lots of bugs (and plant) weirdness!
