Pour ceux qui comprennent le français, Yann LeCun a fait une leçon magistrale avec craie et tableau dans laquelle il décrit les algorithmes des grands modèles de langage (LLM) et des modèles du monde (world models) qui attirent maintenant son attention.

If, like me, you are not an AI expert but are curious about it, this interview with Joëlle Pineau is fun to watch and listen to.

L'informatique quantique diffère profondément de l'informatique classique. Tania Belabbas de l'Institut quantique - Université de Sherbrooke fait appel aux mathématiques pour nous expliquer le fameux qubit.

CBC Radio's science show 'Quirks & Quarks' celebrated its 50-year anniversary in a fun episode that invited experts to discuss the last 50 years of research in cosmology, genetics, climate, computers, agriculture and speculate on the next 50 years! 🧪

The Saxby Gale severely hit Atlantic Canada on October 4 & 5, 1869. On the 150th anniversary of this storm, @ryansnoddon.bsky.social wrote a nice summary of its evolution and impacts, including major flooding between Amherst and Sackville.

Le 17 août 2017 occupe une place spéciale dans la mémoire des astrophysiciens. En cette journée, les caractéristiques d'un événement d'ondes gravitationnelles ( #GW170817) suggèrent la première détection d'une fusion d'étoiles à neutrons.

How does oxygen get from the ocean surface layer to the ocean's intermediate depth and bottom waters? 🧪🌊

I wrote a brief overview of the processes involved and the key regions of ocean ventilation:

Map projections make compromises between accurately representing either area, angles, or distances. Tissot indicatrices (blue circles & ellipses) inform us visually about map distortions. Standard parallels here are at 50°N and 70°N for the Albers and Lambert projections. 🧪

Always interesting to see how successive El Niño events and La Niña events modulate the global warming time series. The 1997-1998, 2015-2016, 2018-2019 and 2023-2024 El Niño events are easily detectable as bumps in this graphic from @copernicusecmwf.bsky.social.

Weather apps on our smartphones appear kind of magic!

But formidable international observations, data exchange, and forecasting infrastructures are behind this "magic". 🧪

For Canada Day, I am proud to announce I migrated my website to a web hosting company owned and headquartered in #Canada: @whc.ca. I took advantage of the move to redesign my trilingual (English, French, Spanish) website using WordPress, a new skill for me. #CanadaDay

Absolutely! Breaking apart the operational teams that are creating and maintaining these extremely valuable data products can be done quickly. Rebuilding these teams later will take much longer. Such ideological budget cuts are part of the broader War on Science.

In early 2016, before #Trump won his first Republican presidential nomination, a prescient book by @shawnotto.bsky.social described three components of the war on #science.

1) Industrial
2) Religious/Ideological
3) Identity Politics

Here's my review of Otto's book

After subscribing to the #WashingtonPost for seven years, I cancelled my subscription.

For me what moved the needle beyond the "no repair zone" was #Bezos 's recent heavy-handed decision to control content in the Opinions columns. This caused another resignation today.
