@KeithDevlin@fediscience.org

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!

Much of the Internet "debate" about algebra seems to stem from lack of awareness of what the subject is (versus the arithmetic method it was long ago) https://tinyurl.com/2p9myzt5

R.I.P. Daniel Kahneman. You had a massive influence on many of us, and we will forever be in your debt. https://behavioralpolicy.princeton.edu/news/DanielKahneman

In response to repeated requests, (which I co-founded) now provides schools with access to teacher-specified collections of our math-learning puzzles. The Web-version of the full, adaptive game is still available, as the "Family" option. https://brainquake.com

Voting in yesterday's Senate race shows how California is now two very different political entities with a clear dividing line

"A majority of voters think the economy is in poor condition". WTF? The level of sheer ignorance beggars belief. We lead the world in recovery from the pandemic, by a large margin!

Algebra ain't what you think it is. New post in my Mathematics Outreach Project blog, where I look at those recurring Internet debates where people get different answers to a simple arithmetic problem, such as "8 ÷ 2(2 + 2)". https://sumop.org/blog/

The late afternoon sun yesterday really brought out some of the beauty of downtown San Francisco, prompting me to make a slight detour through Yerba Buena Gardens. We are fortunate that Red State Americans think we live in a dystopian cesspit, so they stay the hell away 1/2

Niklaus Wirth, the computer pioneer who created the language Pascal (which was my language of choice for many years after graduating from Fortran, Algol, and Basic) has just died. He was a giant https://en.wikipedia.org/wiki/Niklaus_Wirth

Bummer. Seems the supply of genuine English cheddar in the US has finally dried up. NONE in my local stores. Irish and Australian (prevalent) are good, as are some American cheddars, but to my taste not the same. Another fail

Shout out to @automattic, the folks behind , etc., for providing great customer service.

I've been making modifications to profkeithdevlin.org and my 90s era expertise with unix, html, etc. is hopeless in the css world (which I guess is the online media equivalent to my beloved, but now rusty, LaTeX).

now struggle with the stuff they helped create ☹️

I don't know the fine details of this report, but I suspect that most doctoral dissertations include some language found elsewhere. The PhD is typically an academic's first "published" work, and most of us necessarily rely on our supervisor for guidance and approval. https://www.nytimes.com/2023/12/20/us/harvard-claudine-gay-plagiarism.html

Harvard makes the right decision for any university to make in this circumstance. Of course context matters; in any utterance. Stefanik herself used the word "genocide"; should she be canceled? https://www.theguardian.com/education/2023/dec/12/harvard-board-backs-president-antisemitism-row

Sloane's list of Integer Sequences turned 50 this year. And modern Set Theory (including the Continuum Hypothesis) turned 150 a few days ago. The December "Devlin's Angle" post for the Math Assoc. of America pays due homage to both https://mathvalues.squarespace.com/masterblog/category/Devlin%27s+Angle

Presumably some shit. One gate agent at CPH checking every passport in great detail. So late getting all on board we lost our landing slot at LHR. Still sitting on the tarnac in CPH an hour after we should have left and no info on when we will take off.

Arrived in Odense, Denmark yesterday. Where regular gasoline costs $8.20 per gallon. American gripes about the "high" cost of gas look crazy to Europeans #gas #gasprices
