Calling my #astrophotography chums in the Americas: will you be staying up late tonight with your telescopes trained on the Einstein Crater? Impact: 02:34 EDT; 4 tonnes of Space-X metal (15m x 4m diameter) travelling 5400mph Expected: 50km high plume containing ~1Mkg of debris 😲🔭

"Will I be able to see the crash?" Probably not, but that doesn't mean friends in the Americas shouldn't try (daylight for those in Europe): look to the eastern limb of the Einstein crater. The @eso.org VLT will observe it & NASA’s Lunar Reconnaissance Orbiter is taking before and after images! 🔭🧪🛰️

Writing a book is so weird because before it’s released there are half a dozen REALLY IMPORTANT DEADLINES for drafts & edits and each completely consumes you & is impossible to explain. “I just spent 72 hours locked in a room doing my copy edit review; I forgot what the sky looks like” “…congrats?”

Bluesky is a "liberal bubble" because fascist chuds can't get traction without algorithmic assistance and because people here trained themselves to block "debate me" trybois the instant they roll up

Bluesky's new CEO Toni Schneider on the platform's reputation for being a liberal bubble: "Yes, we definitely want that to change. It is already changing. It certainly wasn’t designed to attract one specific group of people."

I think we can say this is the spiritual opposite of Biden’s loan forgiveness program, which targeted public service degrees for debt relief. I don’t think he needs much defending, but the way people blamed him for SCOTUS and the GOP stonewalling debt relief was a real low point in our politics.

President Trump is banning students majoring in degrees that don’t make enough money from taking out college loans. Degrees for social work, art, religious studies, teaching aides, and music will be hit the hardest. trib.al/aaAEu6v

I'm on Day 3 of my doing-nothing-but-copy-edit-review writing-cave work period to finalize my second book and I'm fixing up little bits of tone and wording and the absolute best I can do to describe how I know if a sentence needs to get fixed is when it makes my brain itchy. Language is weird, man.

I’ve seen a lot of my colleagues’ interactions with Claude working on research problems & it would be easier for me to accept it as a serious scientific tool if it didn’t end every single response with the LLM equivalent of “you want fries with that?” — constantly trying to goad you into asking more

In light of the “good faith questions” discourse I just wanted to re-up @reveleth.com’s fascinating podcast about the complex (and frequently appalling) history and present of policing sexual biology in women’s sports.

Hello new people! My latest project was a 10+ year labor of love and it would mean the world to me if you checked it out. www.tested-podcast.com It’s a narrative, deep, complex and suspenseful story of gender, sports, science, and “fairness.”

Today's copy edit dilemma: a plum pudding is, to a modern American reader, not a pudding. Also it does not contain plums. But if I tried to call it a fruitcake I would most assuredly be haunted by the ghost of J. J. Thomson.

Same with gender-affirming care for kids. Good-faith concern would be, "gee we should be making sure kids are appropriately assessed before receiving care and don't end up regretting it," realizing the numbers are tiny, kids are assessed and regret rates are miniscule and then dropping it.

Good-faith concern on this issue would be going, "hmm, professional sports leagues should probably have some standards in place to ensure trans competitors aren't getting an unfair advantage," googling for 5 minutes, realizing every sports league already has those standards and dropping it.

i don't believe anyone has "good-faith" concerns about trans women in sports in 2026. there's been too much time to hear the actual evidence, the actual people affected, and the role the debate plays in attempts to purge trans people from American life. anybody picking that side has made a choice

It's a point I've been trying to make for a long time: there is no good way to meet even 10% of current demand for animal products. They trash the living world, whichever way you do it. If you want to reduce your impact, switch to a plant-based diet. www.theguardian.com/environment/...

Organic eggs have worse impact on climate than eggs from caged chickens

Adopting organic free-range model in UK could lead to greenhouse emissions equivalent to 2,316,000 tonnes of CO2, study suggests
