Ed is correct. In fact Davy at first suggested "alumium" before switching to "aluminum". Anyway, nice to meet you too.

SciPost is a decade old! 🎉

Looking back, we feel immense gratitude for your engagement and support, without which none of this would have been possible.

You are our authors, Fellows, referees, readers, advisors, and sponsors: our everything.

We hope you're ready for more; we certainly are.

The best framing I've heard is to distinguish the AI system from the virtual assistant character. The (fictional) assistant that the AI-generated text depicts suggested/encouraged etc., in the same way any fictional character can, the AI itself didn't.

Jamming is a really cool "what if?", making use of some surprising loopholes. It was fun learning about this. For those who want to know more, I've got a "bonus info" blog post on the way.

A Window on Absolutely Everything It's often said that in quantum physics, everything that can happen will happen. One way this comes up is in something called a path integral, used to calculate the probabilities of quantum events. If you want to find what happens to a particle traveling from point A to point B, you have to add up a contribution for every path, no matter how windy, that goes between A and B.

Everything that can happen will happen. Thus, we can learn something about everything.

What AI Physicists Are Missing and What They Aren’t I've seen a couple more thoughtful takes on use of LLMs for physics lately. This blog post by Minas Karamis is particularly nice. He points out something that I've said a version of: an AI that must be supervised like a student isn't very useful, because the main point of student projects isn't the paper at the end: it's training the student.

Some more thoughts on "AI Physicists":

Sabine Hossenfelder pointed out that the original press release mentions electromagnetism, but not specifically magnetometry, and speculated they might actually be referring to an IR camera.

I've definitely had copyeditors check references for JHEP, and I think also for various APS journals. JHEP uses Springer.

I had the impression they did, just after acceptance. I've had a bunch of questions from copyeditors about what citations correspond to, and I'm guessing they're not doing it all by hand.

ArXiv to Leave Cornell Yes, I'm late to the party on this one. A few weeks ago, arXiv.org announced that it will be leaving Cornell, the university that currently manages it, and establishing its own nonprofit. arXiv is a crucial part of the infrastructure for physics, mathematics, computer science, and a few related fields. Researchers post papers to arXiv as what are called "preprints" before the papers are submitted to a journal.

Old news, with my thoughts on it:

Physicists of Bluesky! I'm writing a piece for @quantamagazine.bsky.social
: "What is Mass?" a collection of different perspectives on mass in physics, in the vein of Natalie Wolchover's "What is a Particle?" piece a few years back. If you've got a cool perspective to share, send me a message!

Trust Is a Tree Scientists trust what they think they can verify. In principle, you can work your way through the proof of every mathematical theorem. With enough money and time, you could replicate every experiment. For every expert opinion, you could dig through the literature and find how it was justified. And while a scientist can't actually do that for every field, they might be able to for the ones they care about most.

Scientists trust what they can verify. Journalists have to trust differently.

The Twitter of Physics The paper I talked about last week was frustratingly short. That's not because the authors were trying to hide anything, or because they were lazy. It's just that these days, that's how the game is played. Twitter started out with a fun gimmick: all posts had to be under 140 characters. The restriction inspired some great comedy, trying to pack as much humor as possible into a bite-sized format.

If you see a physics paper crammed into six pages of two-column text, here's why:

As in, if a bunch of evolutionary biologists chat at lunch about how dumb the latest Colossal press release is, I'd expect the molecular biologists on the other side of the department to eventually pick up on that and have a similar opinion. If not, I'm guessing biology is more siloed than physics.

Went back to Twitter to check something and @deontologistics.bsky.social reminded me of this meme, I genuinely think the best meme to ever be produced by Philosophy Twitter.

I'm curious how, despite that reputation, Colossal manages to hire those scientists. This isn't meant to be a "gotcha", it's something I'm genuinely wondering. Do they pay way above industry average? Are recruits mostly true believers? Are they getting by on weaker talent?

About the OpenAI Amplitudes Paper, but Not as Much as You’d Like I've had a bit more time to dig in to the paper I mentioned last week, where OpenAI collaborated with amplitudes researchers, using one of their internal models to find and prove a simplified version of a particle physics formula. I figured I'd say a bit about my own impressions from reading the paper and OpenAI's press release. …

A few people have asked me about this paper. This is a long piece, but probably not all you were looking for.

I've been reminded more than once recently of something I think should be part of a start-of-career scientist's training: If you find yourself in disagreement with another school of thought, your job is not to write papers showing why the adherents of that school are all benighted fools. Rather...

Practice, Don’t Memorize, Understand Justifications, Not Stories Teaching is one of those things that's always controversial. There seems to be a constant tug of war between two approaches. In one, thought of as old-fashioned and practical, students are expected to work hard, study to memorize facts and formulas, and end up with an impressive ability to reproduce the knowledge of the past. In the other, presented as more modern or more permissive, students aren't supposed to memorize, but to understand, to get intuition for how things work, and are expected to end up more creative and analytical, able to come up with new ideas and understand things in ways their predecessors could not.

In which everyone is wrong about teaching:

For a while, I've been meaning to ask you how war in D&D settings ought to work when they have access to scrying and teleportation. I guess we're finding out.

Hypothesis: If AI Is Bad at Originality, It’s a Documentation Problem Recently, a few people have asked me about this paper. A couple weeks back, OpenAI announced a collaboration with a group of amplitudes researchers, physicists who study the types of calculations people do to make predictions at particle colliders. The amplitudes folks had identified an interesting loophole, finding a calculation that many would have expected to be zero actually gave a nonzero answer.

Could we mechanize scientific creativity? Not with these papers!

Pointy at one end - the painful sharp end when you first start reading it - and rounded at the other - the pleasant end when you've learned the material and are wanting to review it or look up precise details.

That raises an interesting question: according to your intuition, should Bourbaki textbooks be pointy or rounded?
