Bluesky will trap academics in the same way Twitter/X did: blogs.lse.ac.uk/impactofsocial… 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.

"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

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/@ColinTheMathm…
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?
Wait ! What ?
While Toby Young is in the news, let’s remember the time when he added 2 and 2 together to get five (his calculation would suggest 1% IFR not 0.1%).
