An AI ChatBot solves a long standing Erdős problem. New "Devlin's Angle" post for the MAA. https://maa.org/math-values/ai-solves-an-80-year-old-erdos-problem/
I'm looking forward to my Farewell Lecture at Southern Denmark University on 2 June, but sad that my five-year Visiting Professorship is coming to an end. I've enjoyed my annual stays in Odense - a few weeks in a civilized country not at w…

Intriguing perspective on MAGA from "The Last Republican", former GOP Congressman and impressive American patriot Adam Kinzinger https://open.substack.com/pub/adamkinzinger/p/the-humiliation-is-the-point?utm_campaign=post&utm_medium=email
This is why Adam Kinzinger is called "The Last Republican". All the others sold out to anti-American bigotry and hate https://open.substack.com/pub/adamkinzinger/p/you-gave-him-your-faith-and-now-hes?utm_campaign=post&utm_medium=email
And still the Republican Party in Congress worships him and stands (in silence) behind everything he does. Watch how they vote; that's where their beliefs lie.

About
Mathematician (Emeritus Stanford), author (inc. many for a general audience), and avid cyclist. For many years "The Math Guy" on NPR. Co-founder of the ed tech company BrainQuake. I write an edited monthly blog for the Math. Assoc. of America called "Devlin's Angle", often (not always) about #mathed. The ranking site AcademicInfluence.com ranks me No.1 of the world's "Ten Most Influential Mathematicians 2000-2020". [https://tinyurl.com/w6p2bx5s] Being active on sites like this probably helped!
