You can also include economics, as well as physics.
Terence Tao: The math behind today’s LLMs is actually simple. Training and running them mostly uses linear algebra, matrix multiplication, and a bit of calculus, material an undergraduate can handle. We understand how to build and operate these models. The real mystery is why they work so well on some tasks and fail on others, and why we cannot predict that in advance. We lack good rules for forecasting performance across tasks, so progress is largely empirical. A key reason is the nature of real-world data. Pure noise is well understood, perfectly structured data is well understood, but natural text sits in between, partly structured and partly random. Mathematics for that middle regime is thin, similar to how physics struggles at meso-scales between atoms and continua. Because of this gap, we can describe the mechanisms but cannot yet explain capability jumps or give reliable task-level predictions. That mismatch, simple machinery versus hard-to-predict behavior, is the core puzzle. ---- Video from Prof @Briankeating YT Channel (Link in comment)

First clip from DreamWorks' ‘FORGOTTEN ISLAND’. The film follows 2 best friends trapped in a mystical world but their only way of escape is to erase all their memories of each other. In theaters on September 25.

Here's my best attempt at explaining what I think this open letter is really about. It's not just the math elites protecting their status. Imagine a tribe of monkeys who can see a dense grove of fruit trees at the center of the jungle. They all want to go there, but the jungle is dense and dangerous and there's no path. They offer a prize to any brave monkey explorer who can retrieve a particular kind of golden fruit that only grows at the absolute center of the grove. Officially, the goal is to get the fruit. But that's not really what the tribe cares about. What they actually want is for someone to discover a path through the grove. Once a path exists, everyone can follow it and share in the prized fruits. One day a strange bird appears. It flies directly over the trees and easily picks up the golden fruit, dropping it neatly at the monkeys' feet. By the rules of the prize, the bird has done what was asked of it. But the monkeys are dissatisfied. The task required no bravery from the bird, and more importantly, there's still no path to the grove. I think this captures some of the discomfort mathematicians have with AI. A correct proof is nominally the prize, but much of the value lies in the path to the proof: the concepts, techniques, and understanding that the proof creates. Human solvers create these naturally so there was no need to make them part of the prize. AI solvers don't. Even worse, they destroy the value of the prize which demotivates the human solvers and leaves the field impoverished.
BREAKING: Terence Tao and 24 other Fields Medalists just signed a letter telling AI companies they're destroying mathematics >headlines: AI solves famous math problems >25 greatest mathematicians respond today >"we are witnessing a general threat to intellectual work" >ai labs are treating math problems like a benchmark you can brute force >“solutions are announced in a rush, leaving no time for a proper writeup and citing relevant previous work of others" >they're talking about openai >"this raises severe attribution and plagiarism questions" >they're definitely talking about openai >openai offered to put math professor name on navier-stokes proof >condition: abandon his coauthor bc he works at anthropic >"the most precious resources of our profession are students and ideas" >for the labs the most precious resource is GPUs A Severe Misalignment of AI in Mathematics

A new oddball antitrust case: grocers are suing NYC over Mamdani's grocery stores. They say their low prices constitute predatory pricing. The odds of this case winning are about as high as Trump becoming the next mayor of NYC. The funniest part is where the plaintiffs say it's anticompetitive because the government can sustain low prices indefinitely without ever "recouping" their losses through monopoly prices. In other words, the alleged anticompetitive harm is that prices will be low forever. Not a promising theory of harm!

Grocery margins are low is a frequently rehashed point to argue against Mamdani’s public grocery stores. Grocery is indeed a low margin business. But its median return on invested capital is above that for all firms, so it is NOT a low profitability business. Let me explain. 🧵

How to address global imbalances? What are its proximate causes and what are not? What about sectoral imbalances? Solutions? Our report on global imbalances handed in yesterday to President @EmmanuelMacron for the G7, written with @helene_rey, Axel Weber and Chon-En Bai.

New in @AEA_Journals' American Economic Review: migration doesn't hollow out the home economy — it builds it up. More than 75% of the long-run income gains from migration are domestic. The home economy itself grows. Here's what we found: 🧵

I cannot speak to what is a 'legally' sound application of Section 122, however I can make the following economic points as there is much confusion about persistent US trade deficits and a balance of payment crisis. The difference is similar to suffering from chronically high cholesterol versus having a heart attack. US trade deficits are large and need to be brought down. Reducing US fiscal deficits is important. At the same time, there is no doubt in the US ability to pay the world and therefore no crisis. There is high cholesterol but not a heart attack. In the early 1970s the US did have a heart attack. That was when the dollar was pegged to gold and other countries were pegged to the dollar. The US was in real risk of running out of gold to make its payments which then led to the collapse of Bretton Woods. The difference between persistent trade deficits and a BoP crisis is not semantics. The policy actions required to address them are not the same. A 150 day tariff cannot reduce persistent trade deficits and the US is not having a heart attack.

woah, I've now read Google and DOJ's proposed remedies for Google's 3rd antitrust defeat (adtech). I threaded Friday's hearing but this full doc is nothing short of beautiful. Best stuff may be missed so hear me out. This is a huge deal - 10yrs, "lifeblood of the Internet." /1

This is an incredibly important paper that I think all professors TAs, curriculum designers, EdTech developers working on AI tutoring tools, educational policy makers, academic administrators and et al. should read it

Finally, I'd be remiss if I didn't mention Signet in Manilla. They're a multi-brand store, not necessarily a maker, but they have such great taste in both casualwear and tailoring. If I was in Manilla, I would make a beeline to their store and buy whatever they recommended.

My thought exactly
Doctors should stop prescribing antibiotics to treat bacterial infections. All the existing evidence showing health benefits has serious shortcomings, and the data show that antiobiotics massively increase mortality. (Read to the end before commenting)
