We have made a world where you barely own anything! At very best you’re leasing it from a hopefully benevolent faceless entity! Read a book!

I haven’t read the article about the Brown professor. Did they get suitable approval to release grade information about the entire class? What’s the ethics here? A class is not by default a case study.

Hi mutuals! I'm seeking a writing buddy (on zoom or discord or whatever that's not a Meta product) for a couple hours a week. I can't seem to self-motivate but knowing that you are *also* trying to write is helpful. (I have a book deadline that's too far away for adrenaline or panic to help...)

Oh hey, it’s some new art! Here is: Rigid & Non-rigid transformations

Might be naive of me, but I didn’t think there was another option.

@chanda.blacksky.app explains how Sankofa, the idea of going back and getting what we’ve forgotten, connects to cosmology, Black history, and the origins of the universe.

Le Guin on the idea that there is a secret to getting good at writing.

This is such a delightful opening paragraph for a paper.

#Onthisday in 1852, in the Corinthian Hall of Rochester, NY, Frederick Douglass gave his famous speech now known as "What to the Slave Is the 4th of July?". The fact that it was given on the fifth and not the fourth was significant: publicdomainreview.org/collection/f... #otd

Re-upping this thread on Thomas Paine since he seems to have entered the Bluesky chat on this July 4.

I love America because I had chicken laab for lunch and I’m having beer and fish tacos for dinner.

“The message that I always bring when I have a chance is that, when the text that comes out of one of these systems makes sense, it’s because we are making sense of it. This is also in the stochastic parrots paper.”

This paper has been a REALLY long time coming. It's about a course I taught for many years called Tools of Inquiry, in which I try to teach students to ask and explore their own mathematical questions, including with technology. It's a little like an introduction to research experience at scale!

A 24x24 section of a decomposition of the infinite knight's graph into four 2-factors. The vertices are where eight "strands" meet at a point. If you zoom in, you'll see that each vertex has two yellow strands, two blue strands, two black strands, and two red strands.

All that textual analysis, and the fundamental question is never asked: under my rule, could you have chattel slavery? Get the fuck out. You cannot have an eternally replenishing population that never gets rights under the 14th amendment. That's the point.

Thinking today of all the restaurants near me that have good shrimp dishes.

🚨 you are closer to this xmas than last xmas. 🎄🎁

I have lived in an exceptionally diverse neighborhood for most of my adult life now, and can’t help but think the “loneliness epidemic” might find a cure in investing in good third places

Excellent resource from @hannahnpbowman.com exploring a theological basis for abolition. christiansforabolition.org/wp-content/u... #prisonabolition #restorativejustice #Quakers

8yo (a lefty, like me) is learning from @hannahnpbowman.com about the lefty power in the story of Ehud in Judges. She is giggling constantly.

I started a blog! First post: what topologists find in high dimensions akivaweinberger.wordpress.com/2026/06/24/e...

Dr. Simmons presents a modest proposal for updating academic job interviews.

When you ask chat or Claude or Gemini, I don't want you to think about WHAT you are using. I want you to think about WHO. brookshire-team-trash.beehiiv.com/p/who-you-ar...

As someone whose motto is “resist simple narratives”, I appreciate Hank Green’s frank answer to this question—the issue is complex. (As he admits, he is not an expert, but he is one of the more well-informed among us non-experts.) youtu.be/H_c6MWk7PQc (Also this video is from last December.)

What do mathematicians do? How do they make new mathematical discoveries? Why does that matter for K-12 math education? If you are a math teacher and you are curious about these questions, join in on "21st century mathematics" in July! Free, online, and flexible. www.youtube.com/watch?v=5UIx...

Situational awareness for your Monday. How’s the air out there? During the latest LAFD update, crews said they’re making headway and expect knockdown soon. Chief Jaime Moore said “two more days, possibly three” for smoke. AQMD’s particle pollution advisory extended another day, into Tuesday

According to my wife, my most dad-coded recent activity was just last week, when I cleaned the car before we went out on a day trip with a friend.

Post one (1) photo of a painting that you took with your very own hands.

This week in culture: we finished watching The Good Place and listened to the soundtrack of SIX about fifteen times.

Why does Bono never take his glasses off? He still hasn’t found what he’s looking for.

Math folks, do you love this or hate it: work on a calculation on and off for several months, get an approach that seems ok but is a bit ugly and difficult to prove, then find a more elegant approach that should have been obvious from the beginning and wrap the whole thing up in a couple of days?

Here's one strategy that can help improve your mental math

This whole thread up & down is important and insightful. I want to add one linguistic point here:

How do you make the city of L.A. a little less broken? Or, dare we say it, well-functioning? Read more about Wednesday’s City Charter fight in today’s newsletter. lamaterial.com/p/can-l-a-be...

Frog put the cookies in a box. “There,” he said. “Now we will not eat any more cookies.” “But we can open the box,” said Toad. “That is true,” said Frog.

Update: was not so hard to do this differentiation (thank you Leibniz integral rule) but I also found a much simpler way that gets around it and gives a good enough estimate.

this is what they want to take from us

Mister Rogers’ Neighborhood is now officially on YouTube. Current.org reports "up to 10 new full episodes added to the channel monthly, ideally based on a theme or holiday." There were 896 episodes filmed. Plus compilations. www.youtube.com/@MisterRoger...

Update: we finished season 3 this afternoon. Summer break is great. (Parents were working while the TV was on, but we were all together in the living room.)

Also, for those who missed it when it came out, an essay on "Raiders" and why it's so great, and, yes, how it has aged over the years: whatever.scalzi.com/2025/12/13/t...

I see the news is just Mad Libs now.

I'm going to have to differentiate this double integral, aren't I

I'm trying to make sense of it, this Quanta piece from a few years ago is helpful for the "unfolding the billiard path" piece: www.quantamagazine.org/the-mysterio...
