It amazes me that people think of 'do-gooder' as an insult, that always blows my mind -- Kevin Bacon

I don't know if @RoyalMail will see this, or if they will response but I just got a: "Package was not available when we called." You never called. We were in We were watching the front door You never called. You take our money, and then lie.

Gracias @jamestanton y @ColinTheMathmo por la demostración experimental, en un maravilloso evento de cierre, del primer principio de la matemática: tras una pregunta lo suficientemente sencilla se encuentra el placer y el descubrimiento de una sucesión infinita. #EduCaixaMAPS

Bluesky will trap academics in the same way Twitter/X did: blogs.lse.ac.uk/impactofsoci… Dr Mark Carrigan is a Senior Lecturer in Education at the University of Manchester. Are any of my followers on BlueSky? Will you post this there?

This is a moment to remind people that Twitter can read your so-called "Private Messages". PMs with certain links in them are being blocked. Elon and friends have access to your DMs. Remember that.

(🚨) MAJOR BREAKING NEWS: ELON MUSK ADMITS SECRET MASS CENSORSHIP OF HIS CRITICS ON TWITTER Everything he said about what he planned to do with Twitter was a lie. No MAGA can possibly stand by him after this. He betrayed the one principle he said he had. newrepublic.com/post/189770/…

"The web dev of the future will be an underpaid generalist who pokes at chatbot output until it runs without error, pokes at a copilot until it generates tests that pass with some coverage, and ships code that nobody understands and can’t be fixed if something goes wrong."

I've recently been talking a bit about how difficult it is to carefully check even well-written mathematics. I want to try to explain something about this by telling the story of some errors in the literature that (in part) led to the two papers below. 1/n

Good thread. If you follow me (because of maths) and not @littmath, 1/ read the thread, and 2/ give serious thought to following him.

I don't know what they've done, but it's nearly impossible to paste things into the edit window here ... it gets completely screwed. So I *was* going to post a link to the next video in the #G4G15 series, but it's a nightmare. The announcement is here: mathstodon.xyz/@ColinTheMath…

Is there a simple way to see that for a non-constant polynomial with coefficients in R that the complex roots come in conjugate pairs? In other words, if p(z)=0 the p(w)=0, where w is the complex conjugate of z. Ideas? How accessible can this be for secondary school students?
