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!

As a rule of thumb, you can conclude that when Ted Cruz and FoxNews take up a cause, the issue is NOT how and when algebra should be taught in school. ๐Ÿ™„ It's a weapon in the MAGA Republicans' assault on Women and Woke. (For the record, I support both W's. ๐Ÿ™‚)

I've been involved with the Internet continuously pretty much since its earliest ancestor ARPANET days at UCLA ARPANET site #1.

I can assure you that the ARPANET and the Internet into which it evolved were NOT designed to provide a means for a handful of powerful AI firms to suck the world dry without permission or compensation of information en masse, that has mostly been put online for free as a public service, all to enrich the coffers and stockholders of those firms, while giving only lip service (if that) to ethical considerations, and giving the sites from which they slurp data the finger, while laughing all the way to the bank.

Yes I realize I am creating a bubble by blocking fascists, nazis, racists, misogynists, white supremacists, maga, trumpists, assholes, and idiots. However in my defense it is a bubble without fascists, nazis, racists, misogynists, white supremacists, maga, trumpists, assholes, and idiots.

@Ulrich_the_Elder Simpler to refer to that bubble as the Democratic Party. Not totally accurate, but close ๐Ÿ˜

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

KeithDevlin,
@KeithDevlin@fediscience.org avatar

@SmartmanApps Actually, my main point was that the arrival of modern mathematics at the start of the 20th Century changed the entire game, and eliminated the need for all those old calculating rules, with arithmetic becoming essentially a subdomain of algebra, based on axiomatically-defined modern numbers.

"Algebra Rules rules", if you like ๐Ÿ™‚

[I was on the MSEB in 2001 when they published "Adding It Up" to accelerate the change.]

I just found out X/Twitter unilaterally "verified" my old and dormant account there ("because you're an influential user"), now making me look like I'm an idiot who's voluntarily paying Musk eight bucks or whatever it is a month.

Breaking Away & American Flyers introduced cycling to the American mainstream in the 1980s every bit as much as the successes of LeMond, Hampsten, Phinney, et al.

Iโ€™m flummoxed. Just saw on my inactive Twitter account (which still has 112k followers) that the blue tick is back. The Musk team had taken it away when anyone could begin to buy one. And thereโ€™s a notice my account is being reviewed because I purchased a subscription โ€œon another device.โ€ I did not, however, buy a subscription. ๐Ÿ™„

Maybe it's because I'm a naturalized U.S. citizen, but when people threaten to withhold their vote in protest I can't help but wonder what the actual fuck they think they're accomplishing by a) demoting themselves into non-citizen status and b) announcing their asinine decision

Interesting article. But any dog owner will tell you that dogs absolutely recognize the word "biscuit", forcing owners to adopt baroque circumlocutions when they actually want one with their tea.

Viola Fletcher, at 109, is the oldest known living survivor of the massacre. Last year, she co-authored a book with her grandson about it. One night, she was sleeping in a comfortable home in a vibrant community. The next day, it was gone. She still has painful memories every day. https://www.stlamerican.com/black_history/don-t-let-them-bury-my-story/article_463c7b94-eb8c-11ee-8166-7750624a2f48.html

Elon Musk wants us to believe our future is on Mars, but will settling another planet really be as easy as he makes it seem?

On #TechWontSaveUs, I spoke to @ZachWeinersmith about the challenges that will keep us from building space settlements for a very long time.

@parismarx @ZachWeinersmith Many years ago I spent an evening sitting at a bar table with Elon Musk, Peter Thiel, and a few others. The latter was clearly widely read and very, very sharp. Musk came across as shallow and transparently unaware of his ignorance. I guarantee that Thiel remembers who I am and Musk hasn't a clue. Which suits me just fine.

SMH. I know the MAGA Right have a fear of successful women, but the 11-member California State Board of Education voted UNANIMOUSLY for the new Math Framework (which is VERY similar to the OECD's new framework) so thinking one female professor called the shots is absurd

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
