Currently in a physics project with lengthy perturbation theory calculations: Claude Fable correcting the mistakes that Claude Opus made a couple of weeks ago (including the classic trap of an error in the numerical 'verification' that accidentally had masked the error in the calculation that […]

Ich bin drauf hingewiesen worden, dass ich auch auf Deutsch ein #AMA machen sollte. Daher: wenn ihr schon immer eine Frage an eine Astrophysikerin habt stellen wollen, die nächsten 24 Stunden sind eure Chance. Mein eigener Forschungsschwerpunkt ist beobachtende Hochenergieastrophysik, inbes […]

@FMarquardtGroup 100% agreed. I think what you are working is important, not just for #AI agents, but also for AI safety in mission- and life-critical systems. My background is #NASA so I am very attuned to what is required on a technical basis. Later, while working on commercial #autonomous […]

Sneak preview: We have not yet announced this publicly in a big way, but you can have a first look at "Safe Lab Agents". Run AI agents safely inside a sandbox and let them interact with your experiment. Easy setup, plus automatic electronic lab notebook […] [Original post on fediscience.org]

Short discussion with @FMarquardtGroup about how both fediscience and mathstodon instances are cool and we hope it will be a worthwhile platform for many of us to exchange about science! A lot of good science reported so far at IEEE #quantum control in […] [Original post on mathstodon.xyz]

Well done. The #ACL removed ("desk rejected") over 100 accepted papers from the #ACL2026 program and proceedings that contained citations to non-existing literature: "The inclusion of these non-existent references is a clear violation of the ACL Policy on Publication Ethics." Some authors may […]

I have a bit of time on my hands, so let's do another 24h round of #AskAnAstrophysicist, but this time it's a thematic one. ⭐ What do you want to ask an astrophysicist about stars? ⭐ (I am a professional astrophysicist, part of whose work concerns itself with high mass stars & their winds and […]

[rambling grumpy thoughts] This ramble is really to commiserate with everyone who's tired of fighting whatever your fight is. Because, holy shit, there's so much awful stuff to fight right now. Keep fighting. Thank you.

A scary quick calculation: there are 10,375 Starlink satellites in orbit https://planet4589.org/space/con/conlist.html, all coming down within 5 years. That's an *average* of 5 or 6 a day for the next 5 years. And the v2's are bigger than the v1's. v2's are (conservatively) 1000kg and […]

Aww ... So someone who heard my outreach talk (likely at the @clubdiscordia last Thursday) chatted with someone else and suddenly I have an email in my inbox from someone teaching at an art/design school about using some of my illustration as examples in their course. 🥰 I love chance and things […]

I also got a few nice aurora photos last night before it totally clouded up!

I was today years old when I learned that scientists from the 17th century had their own form of "preprints" to lay claim to ideas before they got them officially published. Galileo wrote in a letter to Kepler "Haec immatura a me iam frustra leguntur o.y.", in English "These are now too young […]

Sending peace.

Upside to 2am barn checks for the #BabyGoatCountdown: there were full-sky auroras! (It *finally* wasn't cloudy, yay)

Update. "How France’s #Mistral Built A $14 Billion AI Empire By Not Being American." https://www.forbes.com/sites/iainmartin/2026/04/16/how-frances-mistral-built-a-14-billion-ai-empire-by-not-being-american/ #AI #DataSovereignty #France #OpenSource #USPol #USPolitics

How France’s Mistral Built A $14 Billion AI Empire By Not Being American

Paris-based Mistral wanted to develop a top-tier AI model to rival OpenAI and Anthropic. That didn’t work out. But it turns out lots of folks don’t care if the AI is bleeding edge – as long as it wasn’t made in America or China.
