High near-surface nitrogen-fixation rates that promoted the recent growth of the Great Atlantic Sargassum Belt were tied to greater upwelling of phosphorus from the equatorial Atlantic, according to c...

So much new stuff from SWOT that should be in there, but we will have to write the papers first. Here is a teaser from chapter 5. And if you are wondering what is H_L=5 km,T > 18 s, well that is "some" wave height.

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.

You might have heard that the elliptical orbits of a planet around a star under Newtonian gravity have a kind of *four*-dimensional symmetry. There is a lot of beautiful mathematics behind the ideas that make this notion precise, but here is a simple way to get a handle on the underlying symmetry.

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 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]
