This one was really fun to do. Lots of new ideas discovered in there!

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-...

So cool! 🧪

🌊 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...

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

🌿🌊 #WorldWetlandsDay A recent #URIGSO-led study analyzed 23,000+ sediment samples and found a key gap in a common method for measuring carbon in salt marshes. Addressing this gap is essential for understanding marsh resilience and for guiding blue carbon strategies. ➡️ Read more: buff.ly/T2ubRtp

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...

And the paper is out! Great to work with my good friend @rocangel.bsky.social who led the way. www.seismosoc.org/news/tsunami...

🌊🧪 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... 🧐🌊

Most people know how to draw an ellipse by pinning two ends of a string to a board and sweeping a pencil around inside the string, keeping it taut. But what about the 3D equivalent? Start with an ellipse and a hyperbola in orthogonal planes, with each curve’s vertices being the other’s foci.

I took a class on analog electronics (using Horowitz and Hill, of course) at UCSB from Martinis as an undergraduate and I remember him as an enthusiastic teacher who always had time to answer questions.

Hey fluids friends, we're recruiting in my department this year!

It's great that @johncarlosbaez.bsky.social is on bluesky -- I've learned a ton from him about math and physics over the years. 🧪🔭

In the 1960s and 70s, Syukuro Manabe pioneered ways to model Earth’s atmosphere. In 2021, he received the Nobel Prize in Physics for this work, which is often cited as foundational to modern climate science.

If you happen to be interested in ocean mixing variability, stratified turbulence, or the fate of shoaling nonlinear internal waves on the inner shelf, our recent study has just appeared in JPO: journals.ametsoc.org/view/journal.... Fun to work on this with @alexisonfluids.bsky.social & crew! 🌊🌊🌊

Fun new paper at #SIGGRAPH2025: What if instead of two 6-sided dice, you could roll a single "funky-shaped" die that gives the same statistics (e.g, 7 is twice as likely as 4 or 10). Or make fair dice in any shape—e.g., dragons rather than cubes? That's exactly what we do! 1/n

We have two articles (both by first-time scientific authors) in GRL! First up, led by PhD student Lulabel Ruiz Seitz, we find a simple interaction between lateral stirring and biology that has implications for modeling and observing cross-shore fluxes. agupubs.onlinelibrary.wiley.com/doi/full/10....

We often use discretization to approximate continuous laws of physics, but it also goes the other way: You can use continuous equations to approximate the behavior of discrete systems! Here we'll see how electrical circuits can be modeled using the Laplace equation Δφ=0. [1/n]

Greg Wagner and I just published a paper (link.springer.com/article/10.1...) on wave momentum. It is well known that waves packets in deep water have no momentum, yet it takes momentum to generate them in the first place. Where does that initial momentum go?
