Ok I've designed an LLM prompt to make Google AI just give you a list of links. It's longer than you might think because it kept ignoring the instructions. This is efficient. This is The Future™

Voir Saturne 🪐 depuis l’observatoire de la Sorbonne au beau milieu de Paris… et oui, c’est encore possible ! 🔭✨ Merci à @ParisSecret (compte Instagram) de mettre en lumière l’Observatoire de la Sorbonne et les activités de la #SAF. Voir le reel 👉🏻 www.instagram.com/reel/DYwKIbY...

Eh ben figure-toi que non ! C'est la carte qu'utilisait la NASA pour calculer la position des prises de vue de Mariner 4 en 1965 😅 www.planetary.org/space-images...

wordwank, n. a sport originating in the late '020s in which (traditionally) a baseline human and a large language model attempt to hold a fluid yet semantically empty conversation for as long as possible. one player wins when he maneuvers the other into asserting an empirical claim

🔭 Des astronomes pourraient avoir détecté le premier trou noir primordial, des petits trous noirs formés peu après le Big Bang et qui pourraient former la matière noire. Celui-ci pèserait environ 3 masses lunaires et aurait été détecté par micro-lentille gravitationnelle 😮 arxiv.org/abs/2605.19375

I love canals, so this made me want to do a tour of the midwest US and its half-finished canals - and a boat tour of the finished ones! You can join me on my tour here: mathstodon.xyz/@johncarlosb... A lot of people joined in!

Après une 1ère période de fonctionnement entre 2010 et 2013, puis une 2ème entre 2015 et 2018, le LHC au CERN clôt bientôt sa 3ème période d'exploitation (appelée RUN 3), couronnée par des performances remarquables, supérieure même à ce qui avait été initialement prévu. home.cern/accelerator-...

I’d forgotten this magnificent story about Roger Moore (which Facebook just reminded me of) so I’m reposting it here for the clicks

Someone has been paying attention.

A PhD student at Stanford noticed her classmates were asking Al to write their breakup texts. So she ran a study. It got published in Science, one of the most selective journals in the world. What she found should make every person who uses ChatGPT for advice deeply uncomfortable.

La version sans paywall de cet article (que l’auteur a placé dans le domaine public). gcaptain.com/drowning/

Well worth your time "For too long, the university has ignored the wisdom of the donor class and hired based on academic excellence. Regrettably, this has led to the underrepresentation of discredited viewpoints in elite higher education."

2/2 La célèbre règle du "équivalent humain = âge du chien x 7" est erronée. Dans cet article, l'étude des mécanismes moléculaires & épigénétiques du vieillissement chez le labrador donne plutôt la formule : Âge équivalent humain=16 x ln(âge du chien) + 31 www.sciencedirect.com/science/arti...

Le 23 mai 2005 éclate l'un des plus célèbres conflits éditoriaux de Wikipédia en français : la « guerre de l'endive et du chicon » 🙃. Par la suite, ce débat joua un rôle de repère dans la résolution d’autres conflits liés aux titres des articles ⚖️. fr.wikipedia.org/wiki/Wikip%C...

On peut le dire clairement maintenant : nous nous dirigeons vers l’un des événements thermiques les plus spectaculaires jamais observés en France tout mois confondus, totalement hors du champ statistique de ce qui a été connu jusqu’à présent en mai. C’est absolument délirant : 1/6

The Pont Neuf is the oldest bridge in #Paris - and now a temporary #mountain cave! Parisian artist #JR unveiled his new installation on May 21. It will be fully accessible for three weeks starting on June 6.

On the night of the 17th June there will be a super conjunction of the thin Waxing Crescent Moon and Venus. Will appear within a degree of each other. Sky will be a big bright for the Northern Hemisphere, but should be a fine sight in binoculars or naked eye. 🔭 🧪

Whatever intuitions you formed three years ago when you first heard of ChatGPT (and the people boosting it...), you really should be updating them. I'm but a humble physicist but I'd even say this story is the Deep Blue-Kasparov moment for mathematics

No more cat videos, THIS (thread) is what the internet was invented for. Finally.

This is impressive: it is a problem I had actually heard of. It looks like the solution approach is surprising to mathematicians. It was a general reasoning model rather than a specialized one: bitter lesson time. I think the stochastic parrot is now nuked from orbit. openai.com/index/model-...

Bearing in mind that within the last year I've had many people insist to me that these models can't do arithmetic.

Explain to me why airplane wifi is slower despite being closer to the cloud

Un osprey extrae del agua un pez pompano mas pesado que el mismo y asciende batiendo sus alas, uno de los ataques mas potentes del reino animal

I love this new paper about planets in AGN disks around supermassive black holes! arxiv.org/abs/2605.19241 Naturally, it also helps to motivate some of the crazy planetary systems I've built: planetplanet.net/2018/06/01/t...

It's an oversimplification on my part, but I like to think you could map the rise and fall of the internet to the shift from mainframes (something your employer owns) to personal computers (something you own) and then back to mainfr- sorry, I mean the cloud (i.e. something an oligarch owns).

If you use LLMs to do your data analysis, or if you listen to people who do, you should read this kucharski.substack.com/p/real-signa...

Ok I have this which appears to work but I don’t understand why the "fudge factor" is necessary (set it to 0 to see what happens without it) let alone why it has to be different on each axis (here +, - and 0). Problem with the Desmos solver/renderer? Anyone? www.desmos.com/3d/x0lqkfwqzr
