Almost moved to see these students, who, back in January, were just CVs among a thousand applying to the COFUND #DeMythif.AI program at @univparissaclay.bsky.social (with @dataiainstitute.bsky.social ).
A beautiful start to their PhD journey on AI, uncertainty, and science!

The new #DeMythif.AI promotion is starting today. It is such a pleasure to meet the 16 students of the program in @univparissaclay.bsky.social and @dataiainstitute.bsky.social !

Ah so, thanks to LLM’s, arXiv is becoming a postprint server
Another casualty of the LLM revolution.
In "arXiv’s CS category, review articles and position papers must now be accepted at a journal or a conference and complete successful peer review."

#289 and #290 France lifers in 15'!
So a White-winged Black Tern had been reported for a week on Lake Saint-Quentin-en-Yvelines near Paris.
I drive there, en route I get a note "Near the eastern dam!", I park there, set up the scope and there it is, spectacular black and white pattern!

As an associated editor for EPJC, CSBS before, I always search for referees with private emails, and only then I formalise the invite on the official platform.
Last time, an editor was complaining I was not doing anything because he was not seeing any activity on the platform...

My bank notified me of a suspicious charge on my card. Turns out it was fraud. Had to block it and order a new one.
The merchant? HIGGSFIELD.inc 🤨
Coincidence, I think not!

Je demande à #ChatGPT de me réécrire des paragraphes en anglais.
Ensuite, #grammarly (activé par défaut dans ma console latex) me propose de réécrire des phrases de ChatGPT ("for clarity").
Eh ben c'est nettement mieux.
Peut-être je devrais directement indiquer à ChatGPT d'écrire comme Grammarly

I was intrigued at a seminar where the lecturer quoted in english:
Laplace "Nature laughs at the difficulties of integration"
A good one, but never heard it in French, while I see it is quite popular in the English-speaking academy
It turns out this quote was entirely made up in the fifties! 🧵

Studying the #Higgs boson at the #LHC isn’t about probing some obscure particle; it’s about studying the vacuum that is here, there, and everywhere—now, since the beginning of time and forever, whatever ever is.

Could a Quantum Bubble End the Universe?
A freak particle physics process could wipe out all galaxies and life—but it’s wildly unlikely

Male Wagler's pit viper at Bukit Timah Summit.
The size of my hand. Not obvious in the image, but it was precariously perched on a twig at 1m off the ground.
A guy passing by told me to look for it because it had been around there for weeks, thanks to him.
