Nós conseguimos mobilizar o Brasil ainda a tempo de evitar o retrocesso gigantesco do bolsonarismo (novamente). Não foi cedo o suficiente pra evitar o que aconteceu no Congresso e no Senado, mas mostrou uma coisa: dá pra lutar, dá pra ter esperança. #Lula #Science #Left

I've recently learned that some (all?) US institutions are de-incentivizing collaborations with researchers from China and Russia.... It seems that one is not entirely free to collaborate with researchers from these countries. If one wants, this demands an institutional verification procedure...

30 U.S. Universities Under Scrutiny Over Research Ties with China, Russia and Iran

The Pentagon has ordered 30 U.S. universities, including Harvard and New York University, to review their financial and research ties

Here is an interesting one from Henry Wilton: "There is a long list of mathematical structures and norms that OpenAI seems to be intent on damaging. By refusing to name the authors of their papers, they imply that mathematics is no longer a human endeavour. " (1/4)

“Many of us are grappling with OpenAI’s announcement on 6 October. We feel that it is useful to have an updating snapshot of the community’s gut feeling.”

"(...) it feels like we’ve been working on an archeological dig for 4 years, gradually discovering more and more of a really cool-looking dinosaur skeleton, and then a trillion-dollar company showed up and just blasted the whole thing with TNT, handed us the whole skeleton, and walked away."

The QIP conference deadline will make this week the one with the largest number of submissions for quantum physics arXiv in the whole year. Already today the number of submitted manuscripts was massive. Should quant-ph be subdivided?

"Across academia, incentive structures have long rewarded productivity over understanding, and generative AI now makes productivity easy to manufacture." Clearly *incentive structures* need to change, especially in underdeveloped countries terrytao.wordpress.com/2026/09/27/c...

Being a human who writes, reads, and reviews papers (with AI *assistance* but a lot of attention) in an era where people just use AI for reading, writing, and reviewing everything sucks a lot.

If I understand this, two mathematicians (one at Anthropic) combined a great deal of human effort with LLM input to come close to a famous problem, showing that the Navier-Stokes equations of fluid mechanics developed singularities. But someone from OpenAI might have peeked at their ChatGPT logs...

Dancing very very VERY close to saying “OpenAI stole our almost-complete proof of Navier-Stokes from internal access to our ChatGPT sessions because they were desperate to scoop Anthropic” which is absolutely 100% a believable thing OpenAI would do right now cims.nyu.edu/~tristanb/st...

GPT-1 was released in 2018 and it has now 8 years old. Should it receive the Fields Medal for its problem-solving skills in mathematics, given that it might have just solved one of the biggest of all?

We now have specific architecture plans for fault-tolerant quantum computers. Finally we can ask to within an order of magnitude: how much time will a megaquop take? Assume 10^-6 logical error rate and 1 shot. Basically a Hello World worthy of actually running on a QPU. What's the lower bound?

Don Zagier wrote: “There are two facts about the distribution of prime numbers of which I hope to convince you so overwhelmingly that they will be permanently engraved in your hearts. The first is that they are the most arbitrary and ornery objects studied by mathematicians..." (1/n)

These limitations are determined by the degrees of freedom that support the knowledge of the subject, the ready state, and whether it wants to learn about the past or future state of the object. They give rise to rich landscape of epistemic horizons. E.g., for prediction:

there should be a complexity class for problems where LLM proofs are harder to verify than solve directly

Looking forward to be attending the Superconducting Qubits & Algorithms (SQA) 2026 conference in Gothenburg, Sweden from August 25 to 28. I will be giving an invited keynote talk on the opening evening and present new work on #quantum error correction from our lab.
