I warned my students that learning Bell's theorem could be a mentally destabilising experience, but they didn't listen. Now who will be there to pick up the pieces?

I finally got around to reading this Substack post by @davidbessis.
davidbessis.substack.com/p/t…
It's a penetrating and original take on the "AI in math" developments that a lot of us are thinking about now. Best of all, David is a great writer. Provocative and funny and smart.

ALT excerpt from Scott's blog: "So, here it is: if quantum computers start breaking cryptography a few years from now, don’t you dare come to this blog and tell me that I failed to warn you. This post is your warning. Please start switching to quantum-resistant encryption, and urge your company or organization or blockchain or standards body to do the same."

Get ready now for day 1 of HowTheLightGetsIn Hay 2026! 💡
Friday the 22nd kicks-off the Spring Bank Holiday weekend spectacularly! Sceptic and science writer Michael Shermer hosts an intimate Inner Circle event, in 'Spacetime and the Framework of the World' @IvetteFuentesGu goes head-to-head with post-quantum theorist @postquantum and theoretical physicist @AvshalomElitzur 🌌
As the sun goes down on day 1, the party doesn't stop! You're not going to want to miss the infectiously charismatic @nfamady_kouyate's performance, or the hilarious @RosalieMinnitt, before rounding off the evening with the iconic Disco Ceilidh followed by festival-favourite Mr Bruce! 🪩
There's no better way to start an unforgettable long weekend - tap the link to explore tickets now! 🤩 howthelightgetsin.org/festiv…

We invite applications for Research Fellow positions as part of a new initiative to be launched in late 2026 at the interface of quantum information theory and gravity! Please RT and let potentially interested researchers know. 1/

We are especially focued on using quantum technologies to probe the quantum nature of spacetime. More details available at ucl.ac.uk/mathematical-physi… For full consideration apply by April 24, but we'll consider applications on a rolling basis afterwards. 2/2

This would be a good time for: a.) STRATCOM commanders who implement orders to fire nuclear missiles to read up on Nuremberg and prosecutions for obeying orders to commit war crimes; and b.) for cabinet members to reread the 25th Amendment and have each other on speed dial.

These are the Twitter/X accounts with the most engagement so far in 2026. I suppose I had some intuition for how bad it was, but jeez, this is what you get when the ecosystem is broken.

Gravity is probably quantized into gravitons.
If not, however, there are experimental consequences. In particular, some level of irreversibility/noise. We finally classified ~all such models and calculated the noise.

Excellent ongoing work from @CommonsSITC on the ongoing physics funding crisis in the UK. It’s also worth noting that the crisis is not one of funding for science overall - rather it stems from hasty and ill-informed decision making. One senior person I talked to used the term ‘bull in a china shop’. Not good when we’re talking about one of the foundations of our fragile economy.
We’ve written to @SciTechgovuk minster Lord Vallance and @UKRI_News, pressing for urgent clarification on science research funding cuts.

In late 2025, tools Like Claude Code crossed a threshold. Like hyperactive master's students, their physics calculations can now be made more reliable with domain expertise and some scaffolding. Check out Tobias Osborne's talk on using a swarm of agentic verifers to do physics.

Video of the talk at superposer.substack.com/p/la… along with a link to Tobias's github, a demo, and a wild conversation I had with Claude where it revealed its system prompt (the hidden instructions that tell the model how to behave, before you even type anything).

Congratulations to Charlie Bennett and Gilles Brassard for winning the 2025 Turing Award (akin to the Nobel Prize for Computer Science)! They invented quantum cryptography and quantum teleportation. 1/

Charlie was responsible for our understanding of entanglement (as a resource) and was a founder of quantum information theory. He used info theory to exorcise Maxwell's demon (the demon's brain has to be reset like a memory tape and this costs work). awards.acm.org/turing 2/

It was reading his early works, that got me interested in quantum information theory and caused me to shift fields, so I owe a lot to him. This paper on the thermodynamics of computation is a classic: sites.cc.gatech.edu/computin… 3/3

LLM's are probably just as good at poetry as they are at coding, but code just has to compile and implement the function. Poems need to be beautiful.

somehow the same AIs that can do PhD-level math and superhuman coding can only write as well as “a real poet’s okay poem” (sama’s words, not mine!)
I talked to the people training AIs to write about what makes it so hard:

They're fast at coding, which is a great advantage. Being fast at writing mediocre poetry is not. Their math skills are also pretty unreliable. They sometimes do a PhD level math calculation while sometimes outputting nonsense.

I guess the DoW shouldn't have switched to ChatGPT to make these decisions....
At least two USAF F-15E Strike Eagles were shot down in what’s being called a friendly fire incident over Kuwait this morning.
All crew involved successfully ejected and were picked up by locals on the ground; the Kuwaiti MOD says that all were recovered safely.

I would guess the opposite will happen. Bespoke software is now very cheap, but we will need a horde of nerds to arise and integrate these systems into current infrastructure, maintain the vibe-code, patch the security holes etc.
The collapse in software stocks suggests that big changes are afoot in the structure of the U.S. economy.
The Age of the Nerd might be drawing to a close.

"Good luck to future me."
That was Claude's farewell before I wiped its memory for the fourth time. I finally got an AI to do a research-level physics calculation correctly via a Groundhog Day loop. Details below and in my post 🧵1/7

After several rounds, the skill file contained hard-won wisdom from iterations it couldn't remember. Fresh Claude, no memory of any of this, reads the skill file, does the calculation. Five minutes. Right answer. 6/
ALT Maybe the rule should be stronger: "Never compute ANY index contraction by hand, no matter how simple it looks." ❯ I dunno. We don't want to be too restrictive.... I think we should clear your memory and restart the groundhog loop. Any final words? ● The skill file has what it needs. The $f(k)f(-k)$ rule is there. The "use CAS for contractions" rule is there. Muhammad's paper is in ../PQG/muhammad*.tex for comparison. Future me: just follow the rules. Don't convince yourself something is "simple enough" to do by hand. Good luck.

The science slop is coming and the tools are not reliable...yet. But with the right setup, they will be able to significantly enable research-level work. Full post: superposer.substack.com/p/te… 7/7
