Bernard Vonnegut was a climate scientist who worked on cloud seeding in the same department as Irving Langmuir at GE. Langmuir first reported the upper ocean circulations that bear his name, and also inspired the character Felix Hoenikker in Cat's Cradle, written by Bernard's brother Kurt. 🧪🌊

A firehose of smoke over the Northeast this evening. Just dreadful.
This one was really fun to do. Lots of new ideas discovered in there!
New preprint looking at the question of how the interaction between fronts (~1 kilometer) and turbulence (~10s of meters) affects the exchange of properties between the ocean mixed-layer and interior. Work by Zhihua Zheng along with @baylorfk.bsky.social, Tomas Chor, and Jay Brett. 1/n
OpenAI's claim that this is a central conjecture in discrete geometry is not an exaggeration. This will I think be looked back on as the first time that AI solved a major mathematics problem (defined as a problem that all experts in some subfield had thought about). openai.com/index/model-...
An OpenAI model has disproved a central conjecture in discrete geometry
An OpenAI model solved the 80-year-old unit distance problem, disproving a major conjecture in discrete geometry and marking a milestone in AI-driven mathematics.

🌊 New paper alert! For the first time from space, two NASA missions enable us to observe plankton community composition alongside the physical processes that structure it. 🛰️ 🦠 🌀 Check it out from @tosoceanography.bsky.social: doi.org/10.5670/ocea...
A stunning visualization born from a collaboration with @manlius.bsky.social : 55,486 galaxies and 29,555 streamlines tracing how matter flows across our local universe, built on data from the CosmicFlows-4 project. Article in the first reply 👇
🌊 A team of researchers, including #URIGSO's @nickpizzooceans.bsky.social, has developed a new AI-powered way to study ocean currents. #GOFLOW uses thermal images from weather satellites already in orbit to map ocean surface currents in unprecedented detail, with no new hardware required. 🧪
Our recent paper on using thermal imagery from geostationary satellites to infer surface currents was published! We call the method GOFLOW 🧪🌊 www.nature.com/articles/s41...

#URIGSO postdoc Teresa Schwemmer is testing how limestone-treated seawater affects quahog larvae during their first 48 hours. The work connects to a field study in Winnapaug Pond, comparing juvenile growth near vs. farther from a golf course that applied limestone. 🌊 🦑 🧪 @jaimepalter.bsky.social

I'm only now learning about "vector meson dominance", a big idea put forth by Sakurai and others around 1960. Just as the pion comes in +, - and neutral forms and has spin 0, the rho meson comes in +, - and neutral forms and has spin 1 - so it's described by a "vector", like the photon. (1/n)

First runs in the internal wave channel we are constructing! You are seeing the density perturbations via the Schlieren method. The stratification doesn't go up to the free surface and you can see reflections of the internal waves off that interface and the bottom. 🌊
@baylorfk.bsky.social is not actually a fox. He's a Professor at @brown.edu whose research focuses on ocean physics and its role in the global climate system, and in particular, submesoscale turbulence, mixed-layer dynamics, and improving climate model accuracy through advanced parameterizations

Surface ocean processes impact structure deep into the ocean interior. In our perspective paper, @maratimes.bsky.social, grad student Katarina Merk, and I discuss using physical perspectives to interpret subsurface biogeochemical distributions and why we as a community should care! 🌊

In 1869, long before Einstein, the famous mathematician Sylvester announced that Clifford - the Clifford algebra guy - was studying whether space is curved! Clifford's mission to study this was almost thwarted by a shipwreck. But that didn't stop him! johncarlosbaez.wordpress.com/2026/01/10/s...
Sylvester and Clifford on Curved Space
Einstein realized that gravity is due to the curvature of spacetime, but let’s go back earlier: On the 18th of August 1869, the eminent mathematician Sylvester gave a speech arguing that geom…

On July 29, 2025 a Mw 8.8 earthquake off Kamchatka launched a Pacific-wide tsunami, right as the SWOT satellite flew south-to-north taking altimetry measurements of the wave train. In our new preprint, we pair SWOT with nearby DART buoys to capture the tsunami’s propagation and its source
🌊🧪 Go see Lulabel's talk at DFD if you want to learn more about how wind makes waves! An old question, yet one we still don't know the full answer to.

Here's a view by #Sentinel-2 of the Rhone river plume within the Gulf of Lion waters. Other the change in water colour, and the strong front between the two water masses, I love how there are more wind-induced whitecaps in the bluer waters, although I do not have a direct explanation about it... 🧐🌊
