Every time I hear "10 sigma" event...
BREAKING: Brazil's -19.8% stock market crash on Monday was one of the rarest market events in the last two decades, according to our analysis.
Brazil's EWZ ETF plunged -19.8% on October 26th, marking an 8.4 standard deviation move.
For context, the ETF's average daily move over the last 20 years has been just +0.04%, with a standard deviation of 2.36%.
Under a normal distribution, the probability of a decline this extreme is approximately 1 in 58 quadrillion.
In other words, this event should be virtually impossible under conventional statistical models.
What just happened in Brazil was *almost* impossible.

It's 2026. Your lab throws the biggest Halloween party to celebrate the Death of Mathematics. PIs are wasted in the coffee room, Phds and postdocs dance around a bonfire from obsolete preprints, even Reviewer 2 is having fun
And then the DJ (Fields medal) throws this banger 🎉

My mathematician daughter was browsing in a used bookstore this weekend ... and found this:

Mathematicians complained so much that they got UBI.
there’s a lesson in here
We want to support the mathematics community in turning progress in AI into deeper human understanding and new discoveries. To support that goal, we are contributing $5 million to a new Simons Foundation initiative to help mathematicians examine, understand, and build on results produced by AI, including the results we recently published.
The funding, managed and awarded by the @SimonsFdn will support workshops, conferences, and special programs. We will also provide access to our models and computing resources to Simons Foundation-supported researchers.

Fucking brutal
Thanks to Terry Tao for featuring me on his blog!

people are starting to realize.
there *are* no moats left. the only true moat in existence was intelligence, and now that's out of the equation.

Effective Mathematics: instead of thinking about math directly, you go work in finance or something, make a bunch of money, and then spend that on tokens, asking the AI to solve some unsolved math problems

This is Tristan's perspective on the whole Euler / Navier - Stokes OpenAI issue (he is not in twitter, but he is OK sharing this)

10 remarks on AI and math that can be true all at once:
1. The recent progress is stunning and exciting.
2. The Quasi-Riemann Hypothesis is arguably Fields-medal level.
3. Mathematics is being transformed and there is no way back.
4. OpenAI doesn't give a fuck about the future of mathematics.
5. Half-baked unreadable preprints claiming major results can effectively stall mathematical progress.
6. Some mathematicians are responding with naive, overly defensive comments.
7. The social-media wankers framing this as "OpenAI tramples gatekeeping" have no experience of mathematical research.
8. The product of mathematics is clarity and understanding. Not theorems, by themselves.
9. Mathematics is a critical infrastructure of human cognition. The human need for understanding isn't obsolete and it can't be offloaded to machines.
10. We haven't "solved" mathematics and we won't get there before the Sun burns out.

a while ago I made a bunch of unhinged requests to Amazon's shopping AI about things like "the best conceal carry holster for my dog" and I'm pleased to announce it's paid off

The meme has been proven by peer reviewed research 🤣🤣🤣
Remember JD Vance on the left? "They seem to hate the citizens of their own country and care more about people outside their own borders."
"Just google ordo amoris," he told @RoryStewartUK.
Well, google this new PNAS study: 743,402 people across 121 societies. Conclusion: those who are unkind to outsiders also tend to be unkind to their own. And those who are kind to outsiders are also kinder to their own.
Turns out decent people are just decent people, and assholes are just assholes 💡

Usually exploration can continue after a proof is found. People study it, simplify it, teach it, try its ideas elsewhere.
That takes time and hard work. If we celebrate only the solved problem, we risk overlooking the work that makes its solution useful to other mathematicians.
I would welcome AI that helps us uncover more of the map, including some places we hadn't thought to look.
That is what I hear in this concern by mathematicians : a wish to preserve the understanding that mathematical work creates.
Reaching the city matters. So does what we learn about the world on the way.
