THE FOOTBALL is in the @sciam.bsky.social best-of books list! @dodecalemma.bsky.social calls it "a fascinating mathematical and physical microhistory of soccer balls... World Cup match balls in particular." Thanks, Emma R Hasson (love your bsky handle) and SciAm! press.princeton.edu/books/hardco...

An article I cowrote with Andy Schultz and David McCune providing some highlights from a research project that analyzed various voting systems. theconversation.com/ranked-choic...

Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪

Good morning! Day 4 of the Sandwich Guy’s trial. He is finally wearing a suit (the rest of the week’s evidence suggests he seems to prefer pullovers in cooler weather). The jury has a note for the judge.

Great to see people looking ahead to building back better @princetonupress.bsky.social

NEW: Common Crawl, the massive archiver of the web, has gotten cozy with AI companies and is providing paywalled articles for training data. They’re also lying to publishers who have asked for material to be removed. “The robots are people too,” CC’s exec director told us when we asked about this.

Day 3 of the “no more than 2” day trial of Sandwich Guy. The prosecution intends to rest; the defense hasn’t decided yet. Dispute over jury instructions continues, a few morsels (sorry) to follow.

Back for Day 2 of Sandwich Guy’s trial. In government opening statement: “This case is about the fact that you can’t go around throwing stuff at people when you’re mad.”

On this, National Sandwich Day, keep up with voir dire for DC sandwich guy with @ryanjreilly.com

And now we breathe

Two books I've been waiting for!

Amazon is helping fund a $300 million build of a ballroom for the White House. Independent bookstores are donating to food banks and organizations that help with food insecurity. They are not the same.

Eagerly awaiting my Prop 50 flyer from the Christmas Adventurers.

"Big Tent" Algebraic Geometry. Your ring isn't Noetherian? This book still cares about you.

In the early days of quantum chemistry, before we had computers to calculate the shapes of electron orbitals, one man invented a mechanical machine that simulated their shapes. My latest column for @chemistryworld.com www.chemistryworld.com/opinion/the-...

Since it resonated with the audience, I’ll recap my main argument against AGI here. ‘General intelligence’ is like phlogiston, or the aether. It’s an outmoded scientific concept that does not refer to anything real. Any explanatory work it did can be done better by a richer scientific frame. 1/3

Except that. That's a bad lifeboat.

“When you get a suspicious book, “you look it up to see what else the [author] has written. And you see there's 30 things, and none of them have any reviews, and they were all written in the last two years,” DeMeester-Lane says.”

I haven't read the whole list(!), but saw some excellent math books for unbelievably friendly prices...

Brilliant piece

A personal highlight from the Electric Dreams show at the @tatemodern was Mary Martin's Permutation of Six, 1966 This work repeats and arranges six shapes using generative number patterns.

Inspired by Fred Rogers, @nature.com asked readers to help us 'find the helpers' amid the crisis in American science. What emerged were inspiring stories of researchers, legal experts, data hounds and government scientists who are fighting the dismantling of the US research enterprise. 🧪🧵1/6

Been going through the $1.5 billion Anthropic settlement. First, the settlement is for $3,000 per work for 500,000 works. Despite what this NYTimes article states, it is not for 500,000 authors. @nmamatas.bsky.social pointed this out and I confirmed it. 1/ www.nytimes.com/2025/09/05/t...

Billionaire Larry Ellison helped land top QB Bryce Underwood for Michigan, his wife’s alma mater. Now he’s investing hundreds of millions at Oxford University — and tapped former UM president Santa Ono to lead an institute there. www.wsj.com/business/lar...

"A recurring flaw in AI alarmism is that it treats intelligence as a property of individual minds, rather than recognizing that this capacity is distributed across our civilization and culture" (Maciej Cegłowski, quoted by Becker p112). He calls out the lone genius myth prevalent in US, too.

My calculus teacher would write out a proof on the board, look at us, and ask "Do you believe it?" When we gaped at him in uncomprehending horror, he would sit right down and maybe cry a little. He was very, very old, and Italian. He would say "You are horrible people," and prove it another way.

I urge everyone outraged at this letter to demand that their congressional representatives vote for a ban on gerrymandering at the national level.

Gotta love economists. This is from a paper about researcher views on open peer review:
