Walter Russell Mead (@wrmead) shares a fascinating dispatch on how fast the war in Ukraine is changing, and what it means for the US military: "The first time I went to Ukraine after the war, I went to this drone factory, and it really was remarkable because in real time they were starting to get results from the battlefield, and then they were adapting. But at that time it was very simplistic stuff. They were getting kids' toy trucks and re-engineering them into drones, ground drones that could put a landmine on a tank. I was back there a couple of months ago, and the advances are just unbel… Quoting @patrick_oshag My conversation with Walter Russell Mead (@wrmead).

News flash: OpenAI claims formal proof that Navier-Stokes solutions can blow up. They used 10,000 agents simultaneously, who sent 2.7 million messages and used ~130 billion output tokens. They will not claim the $1,000,000 Millennium Prize for this result. This prize is not going as expected. The first winner refused to take it, saying the math establishment is corrupt. The second possible winner is a team of 10,000 AIs whose human masters turned down the prize. 😆 https://openai.com/index/navier-stokes-solution/ (1/2) OpenAI Related

RE: https://mastodon.social/@tristanbuckmaster/117233413705701198 A remarkable achievement: Alpöge and Buckmaster have managed to push one of the major promising approaches towards constructing blowup solutions to fluid equations --- as developed by Cordoba and Martınez-Zoroa --- to establish finite time blowup for many key fluid equations, including 3D incompressible Euler, with a smooth forcing term. (Previous work by these authors on similar equations could obtain a smooth forcing term for the IPM equation, and a subcritical but not smooth regularity for other equations.)

The Polymath8b upper bound of 246 on the gap between consecutive primes that appear infinitely often, has held since 2014, but has finally been shaved down to 240 in this recent preprint of Julia Stadlmann: https://arxiv.org/abs/2608.31126 . Her paper is a remarkable effort in the spirit of the original Polymath8b argument, except now done by one mathematician (with the assistance of traditional numerical computation, but not modern AI tools). Ever since the seminal work of Goldston, Pintz, and Yildirim, the progress on this problem has proceeded by carefully designing a "sieve" of bounded in… Related

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

quote them on. A translation can be wrong in ways that matter,
especially about tone.
