Brilliant blog post by @3blue1brown.com on "motivated explanations". Lots here to think about for mathematicians (and judging by some papers in quantum info that I read, physicists have a lot to learn here too...) terrytao.wordpress.com/2026/09/18/i...

One month since we submitted this to arXiv. Just counted how many spam emails I received after this came out that invited me to speak at fake conferences or submit the manuscript to bogus pay-to-win journals. The number was 45. And still rising...

Really really sucks that the "Millennium problem solved" headline has to be overshadowed by this ugly drama behind it. Everyone involved should be extensively interviewed to get to the bottom of this...

New preprint! Continuing on our work of describing quantum measurements as a dynamical, unitary process, here we apply these principles to numerical simulations of a more realistic many-body system -- a lattice of hopping particles arxiv.org/abs/2608.11319

Just had a scary moment where someone had guessed the master password I use for my password manager. It's fine now, they still needed a code from my email address so they couldn't get actual access (and I've now reset the password), but still concerning! I thought I'd set a strong password!

Whatever intuitions you formed three years ago when you first heard of ChatGPT (and the people boosting it...), you really should be updating them. I'm but a humble physicist but I'd even say this story is the Deep Blue-Kasparov moment for mathematics

New SciShow! This one was wild to write. I changed my mind on what the story was even about multiple times. What even is a unit? A constant of nature? A law of physics? I thought I knew before writing this script, now I'm not so sure! Find out for yourself here: youtu.be/ONSW0a6ihKI?...

Bit of a physicist pilgrimage in Budapest today. Wild fact: Wigner, von Neumann, Teller, and Szilard... all giants of 20th C. physics, all major players in the Manhattan project, all Jews born in the same Budapest district... the first three even went to the same school at about the same time

Yeah I've basically become radicalised on this recently. Pretty much of the opinion that Everything Bad in the World can be explained by The Bad Black Rectangle and short-form video specifically. Ban social media for under 14s, and over 14s too tbh

Despite working at the Atominstitut for over three years, before this week I'd never seen the reactor while it was in operation. Because the power and radiation output is so low, I reckon this must be as close as it's possible to get to Cherenkov radiation almost anywhere in the world

Great piece. I do scicomm and I'm fine "just" telling fun science stories to the science-enthusiast public... But I know many scicommers want their work to positively impact the world, and there are definitely many bad ideas floating around about how to achieve that. Glad someone's talking about it

This is really good from @seamas.bsky.social
Moreover, such arguments mean engaging with this question in purely vulgar terms, to deploy a miser's algebra in assessing points on a balance sheet, and the returns on investment they imply. At the risk of losing my reputation as a dead-eyed cynic whose heart has been calloused by the evils of the world, I do hold within myself an optimism about space travel that supersedes matters of cost and capital. I think there is value - moral, philosophical, intellectual value - in exploring the one universe in which we find ourselves, and to so as deeply as we can. To gaze at distant stars from Earth, and gaze back home from as close to those stars as
we can get.
