Formalising a well-cited 20-year old physics paper on the stability of the two Higgs doublet model in Lean invalidates the main theorem! "It ... raises the uncomfortable question of how many physics papers would not pass this higher level of scrutiny."

STFC funding for particle physics, nuclear physics, and astronomy—which falls under “curiosity-driven” science—to be reduced to 70% of its 2024–25 budget. This is how you cripple the UK’s scientific and economic future. www.science.org/content/arti...
Intriguing review by @ananyo.bsky.social of a recent history of maths www.nature.com/articles/d41...
The team behind 'The Man Who Knew Infinity' is reuniting to make a new film honouring Maryam Mirzakhani! Ken Ono and Manjul Bhargava (who collected his Fields Medal in the same year as Mirzakhani) are associate directors, Matt Brown writer/director! ❤️❤️❤️🎉 🎉 🎉

We interviewed maths prof Edward Frenkel in Faraday's old rooms on 12 Dec. The video's just out!
Highlights:
29:52 Why self-knowledge is key to avoiding malevolent AI
35:06 Will AI make mathematicians redundant?
56:41 The remarkable effectiveness of physics in maths

In one of the weirder "charity visits" I've ever done, we cracked out some maths last week! Bonus point/s if you know what's going on in these calcs*
Notice that the mathmos there are technically "charity workers", a dopey phrase sometimes used by journos to cover the vast diversity of this sector…
Four academics from different fields will explore how his ideas continue to shape contemporary thinking across physics, AI, economics, and sustainability. Followed by a reception with Hungarian delicacies and wine. It's free! Details and sign up here: www.eventbrite.co.uk/e/can-we-sur...
Seventy years after John von Neumann’s essay “Can We Survive Technology?”, the questions he posed feel more urgent than ever. On Thursday 4 December, I'm chairing an expert panel discussion at the Hungarian Embassy in London on what that essay means to us now. You're invited!
Folks! Amazon.com has done it again! Kindle edition of 'The Man from the Future' on sale for less than $5! That's 75% off. Want to find out what the fuss over John von Neumann is really about and what he actually did? You can now for $4.80!

The director of the London Institute for Mathematical Sciences and I interviewed one of the most restless and original talents in science last week⏤theoretical physicist and innovator Stephen Wolfram!
Watch out for the rapidfire round!

A video of the whole event is now on YouTube! youtube.com/watch?v=8SD9...
Stephen Wolfram is such a legend, I wasn't sure what to expect! But he was gracious and charming, as well as totally fascinating. He even enjoyed my mean rapidfire questions, which he had 90 secs each to answer!
"So Stephen, Is there a God?"
Will post video of the event soon!

...peculiarity of Bengali culture, I highly highly recommend Jhumpa Lahiri's 'The Namesake'. (In fact all of her books but this one relates to the whole familial nickname thing)
...it's still rare that I come across another Ananyo IRL. I've encountered some online and am LinkedIn buddies with another Ananyo Bhattacharya who keeps being asked whether he wrote The Man from the Future (he's got a PhD from MIT). My family call me by my nickname--'dahk nam'. On that...
LOL. I tell people to pronounce it ON-ON-OH. This is not how it is pronounced in West Bengal. However, since it's mostly non-Indians that say my name, it seemed almost like an affectation demanding it be pronounced in the Bengali manner (specially when growing up in the North)....
Of course! Let me know when you want to drop by!
Thanks Caroline! I’m not looking for another job (certainly not a temporary position). There’s younger hungrier writers out there. Alex! Come into the London institute for mathematical sciences with Alok and tim c one Friday! Drinks from 5pm every week.
Not quite everything. Just everything important 😜
Was Gödel's second incompleteness theorem really von Neumann's? Part I

Was Gödel's second incompleteness theorem really von Neumann's? Part II

Despite many arguing we shouldn’t care who exactly did what in science, people seem to care very much. Arguably science wouldn’t progress in its current state unless a scientist could establish priority for a discovery.
Second, there’s strong evidence that von Neumann had a proof of the second incompleteness theorem, which Gödel never proved. Moreover when von Neumann informed Gödel of this, Godel misled von Neumann to prevent him scooping him.
The research reveals, first, that von Neumann suggested to Gödel that he transform his first incompleteness theorem from a statement in logic to one in number theory—hugely amping up its significance.
I’ve removed paywalls from two substack posts on recently unearthed evidence of von Neumann’s contributions to Gödel’s Incompleteness theorems. This work was published after ‘The Man from the Future’ came out, so wasn’t in the book.

The 1943 paper which Andreessen correctly states describes the core tech underlying modern AI is McCulloch and Pitts's “A Logical Calculus of the ideas Imminent in Nervous Activity”, which I talk about in TMFTF.

Eavesdropping on von Neumann, Turing and Oppenheimer would be great fun though VN and Oppie “stalked each other like alley cats” at Princeton according to one contemporary.
VN WAS more interesting than Oppie. Obviously.

Thank you!
Explanatory maths/theoretical physics journalism is hard, important and underfunded. Wish the UK had a @simonsfoundation.org that backed proper, in-depth maths/theory communication with cold, hard cash.
