My dumb theory is that Claude-speak originated because A\ took the "compression is intelligence" thing too far and added some Kolmogorov complexity -esque loss term over CoT

1. We—@eduede.bsky.social, @mjcrockett.bsky.social, Kevin Gross, and I—have a new preprint on the arXiv today, based on ideas that emerged during an @sfiscience.bsky.social workshop in November 2024: The unintended consequences of large language models as a labor-augmenting technology in science.
The unintended consequences of large language models as a labor-augmenting technology in science
As a labor-augmenting technology, large language models (LLMs) have the potential to accelerate scientific activity across the research pipeline. But even if LLMs perform on par with human experts at ...

Having grown up in Sulphur, Louisiana, I can verify that this wikipedia picture of "downtown" is a representative view of Sulphur
I always say that stars are failed brown dwarfs. "Oh no! I've accreted too much gas! My precious hydrogen is being consumed from within!! Horror of horrors!!!"
Add "the Jacobian conjecture is false" to rapidly growing list of AI math breakthroughs
My 5 year old daughter explained to me that Venus is hotter than Mercury because "in the 90s, Venus used to be closer to the Sun than Mercury, but now it's farther"
"because more papers contain more AI-generated errors, greater human oversight is required to check the findings" more papers means more review effort is needed regardless of whether they have more errors or fewer. science needs to be looking ahead to having 5x, 10x, 20x as much to review

Kinda surprised I haven't seen anybody here claiming that, actually, Linus doesn't know anything about software
I'm comfortably walking around Baltimore in the sun, while it's 32C and heat index of 36C... But after a week in Taiwan with heat indices of like 45C every day, it seriously feels nice and dry/cool. Crazy how the body can adjust like that

I need to find @depthsofwikipedia.bsky.social while holding this in my hand (just eaten in Ningxia night market)
it's pretty rare that i get recognized in public so i'll never forget the time i walked into a random bar and a stranger very respectfully tapped my shoulder to show me "small sausage in large sausage"
Dang, even in Taiwan people thought I was in my 20s and only half Asian
I'll summarize this: Mamdani asked NYers to keep air conditioning at 78 degrees. A wave criticism hit online. A MSNBC broadcast pointed out the US Department of Energy recommends that 78 degree figure. Immediately after, the US Department of Energy deleted 6,000 web pages related to energy saving.
AR 4479 is turning into a BEAST of an active region with flaring activity ramping up significantly in the last 24 hours with many M-class flares and even a low-level X-class flare. I bet that we will see another significant flare before the region rotates off the Earth-facing disk.
An absolutely fascinating read!! tldr: the hard and important part of math was always building the scaffolding, while proofs (results) were a byproduct to socially capitalize on this work. AI disrupts that, as it produces proofs without re-injecting useful scaffolding into the system!
powerful essay. much to think about
The moment we've all been waiting for is finally here… On June 29, 2026, NSF–DOE Rubin Observatory officially began the Legacy Survey of Space and Time (LSST)! 🔭🧪☄️🌌 🔗: rubinobservatory.org/news/action-...
Views of National Taiwan University and the city of Taipei, from my office building in the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA).
Study (N=8,097) finds women more likely to finish a PhD before 30 & have children after 35. Men tended to become parents during doctoral studies & often had 3+ children by 40. Early-career mothers had lower citation rates; fathers had no such penalties. www.insidehighered.com/news/faculty...
Female Academics Increasingly Delay Motherhood Until Age 35
“Pronounced penalties” for those early-career staff with children may explain why Ph.D.s postpone becoming parents, a recent study finds.

Last week, I uploaded my first first-author paper as Dr. Prinoth to arXiv, and I finally have time to tell you about it. This one has been a long time coming, and I'm incredibly happy and proud that it's finally out in the #exoplanets world! 🔗 arxiv.org/abs/2606.14490 1/n

Ugh. I used to tell students that they should aspire to communicate clearly, specifically "at the level of Scientific American." I guess I should use Quanta Magazine as an example... other suggestions?
A travesty. Springer Nature offloads SciAm—the most storied science magazine in the US—onto a content mill consortium, LabX, during an almost certainly successful union vote. LabX now says it will lay off 15 people, over 1/3rd of the unit and 60% of the bargaining committee. Pure union busting.
