"In May, solar topped coal nationwide for the first time. In California, solar is fast displacing natural gas."
California has invested heavily in solar and batteries and it is displacing fossil fuels quickly.
Interesting to see solar top coal-based energy production nationwide in May.

If you are a member of the NRA, or know someone who is, I’d particularly encourage you to demand to know why they aren’t leaping to decry the fact that the Trump admin today charged people with a crime for merely •discussing• legal carrying to a protest.
Not because the NRA will have some kind of rational “OMG” moment about it — they’re fashy through and through — but rather because this is one of the many fault lines on the right, and it’s our job to pry those fault lines open.
Then he blows the whistle early, on a Congo throw in the attacking half. 🙄
Bravo to DR Congo. I had Portugal as having an outside chance of making it to the finals. Maybe they will, but they have work to do. And I’m asking questions of Martinez, same as the Euros, of why he feels obligated to play Ronaldo so much. He WAS a great player, and IS still capable or producing a brilliant moment, but those moments are fewer and fewer. Other, better, options exist.

Shear alignment and tensorial Taylor--Aris dispersion of Brownian rods in a circular tube

Abstract: Brownian rods disperse in pressure-driven flow through a coupling between axial shear, anisotropic translational diffusion and Jeffery--Brownian rotation. Classical tube Taylor--Aris theory treats transverse mixing as a scalar process, and existing passive-rod reductions have mainly addressed planar geometries. A circular tube adds two ingredients: the shear strength varies with radius and freely rotating rods sample a three-dimensional orientation space. We formulate a tensorial Taylor--Aris theory for dilute axisymmetric rods in Poiseuille flow by solving the local steady orientation Fokker--Planck problem and using its second moments to close a conservative axisymmetric transport equation. The long-wave reduction shows how each part of the diffusion tensor enters the one-dimensional limit. The radial diffusivity sets the invariant cross-sectional measure and the cell problem for the leading Taylor coefficient; the radial--axial component produces an inverse-P{\'e}clet correction to the migration speed; the axial component gives the direct diffusivity. The central mechanism is the streamwise alignment generated in high-shear annular layers. Alignment reduces radial diffusivity there, shifts the long-time sampling of the velocity profile toward slower streamlines, and amplifies the radial cell response. In strong shear this raises the Taylor coefficient by about \(23\%\) for aspect ratio \(p=1000\) and by about \(30\%\) in the infinitely slender limit, approaching the fully aligned bound. Direct simulations of the full tensorial equation validate the asymptotic coefficients. The same radial mixing operator also gives a Sturm--Liouville spectral model that tracks finite-time relaxation from different radial injections to the long-time Taylor regime.

I'm not even the first person to say things along this line either:
"Another motivation for reducing the steel intensity of modern society is to limit the consequences of geopolitical conflicts. The more steel we produce for peaceful purposes, the more steel becomes available for war and destruction. Remarkably, the production of military equipment is absent from modern steel statistics, and if mentioned, its share is very low. However, in times of war, steelmaking facilities switch to producing steel for military purposes. The steel industry can thus be converted into a weapons industry at any moment, and there is now a lot more steel production capacity available than there has ever been in history."

Oh, and that article also shows the math that proves that there is no way to move to EVs without absolutely blowing through the carbon budget. You have to switch to bikes and trains. There's literally no other way to keep an even close to habitable planet.
Echt bizar @vvdonline.bsky.social sluit in Lelystad gewoon een akkoord met FvD en PVV, het normaliseren van extreemrechts.
