I'm on a minimalism kick and was reminded of these. They're interactive music theory demos, but from math; I knew nothing about this and learned what I know now from you folks here. Anyway, I really enjoyed making these. No instructionas, figure it out :)

An Abundance of Katherines*
The Game Theory of Baby Naming

'Cornell University†

Abstract
In this paper, we study the highly competitive arena of baby naming. Through making several Extremely Reasonable Assumptions (namely, that parents are myopic, perfectly knowledgeable agents who pick a name based solely on its "uniqueness"), we create a model which is not only tractable and clean, but also perfectly captures the real world. We then extend our investigation with numerical experiments, as well as analysis of large language model tools. We conclude by discussing avenues for future research.

We should talk more about what a travesty the bibliography of OpenAI is 16 measly citations for a 165-page paper, of which 5 are just the problem statement. Only 7 are from this century. They failed to cite the method they used. And the guy whom they offered single-authorship & the Millennium Prize

If you're still struggling to understand what's happening with the Brooklyn Democratic Party coup, I highly recommend this article. I found no inaccuracies in it (which is rare, since this is a complex, confusing system and few reporters get every detail right) and it paints a pretty vivid picture.

If Columbia and NYU are now private fortresses that the community can’t access, they should pay property taxes. Actually they should have been doing that anyway, but the jig is so up.

did bluesky hear about Miss Teen Indiana’s Garfield costume
A young woman in a Garfield inspired outfit with a Garfield headdressThe young woman from the first photo is holding a lasagna that says “lasagna my love language”missinteenusa Tonight, Indiana is going Garfield!
My state costume celebrates one of Indiana's most iconic creations-Garfield, created by fellow Hoosier Jim Davis.
Born in Marion and raised in Fairmount, Davis turned an orange cat with a big personality into a character recognized and loved around the world.
But this costume represents more than a famous Hoosier.
The hand-painted comic panels on my skirt share messages inspired by my initiative, Captivating Confidence:
"Our differences are what make us beautiful."
"If we don't have love, we have nothing."
"Outer beauty attracts, but inner beauty captivates."
To me, true confidence is found in embracing what makes each of us different and recognizing that our greatest beauty comes from within. I am so excited to bring a little Hoosier humor, creativity and confidence to the Miss Teen USA stage tonight!
This one-of-a-kind costume was inspired by my vision and brought to life by Indianapolis-based costume designer, Jess West. @jesswestcostumes

Very sad to report that Dolly Parton, one of the greatest Country singers, and far beyond, EVER, has just passed away. This is a true loss for millions of people. There has never been anyone like her, and never will. In her honor, I am lowering the American flag throughout the United States for a one week period beginning tonight at 6:00PM. Rest in Peace, Dolly! The World loves you. President DONALD J. TRUMP

I just went to a combinatorics conference where two of the plenary talks were about AI. I was not impressed by the content. I was impressed by the funding that seems to be going into this stuff though! I guess it is useful for certain things - counterexamples, lit review, whatever. Go for it I guess

An unexpectedly keenly fought contest was for the seasonal cupcake championship. Obviously I'm mostly going to show you the stuff that made me smile, but there's some serious talent lurking in Lincolnshire.
The first prize cupcakes, with the same field shown across the four seasons. The 3d effect of the icing is slightly messing with my head, to be honest.

Mathematician Levent Alpöge found a counterexample to the Jacobi conjecture using Claude Fable! This conjecture claims that if F: ℂⁿ→ℂⁿ is a polynomial map whose Jacobian is invertible at each point, F has a polynomial inverse. Open since 1939. But no more! (1/n)

This video clip of a swan landing on a lake is best enjoyed with AUDIO ON. Mute swans (Cygnus olor) are among the heaviest flying birds & require a long runway, which means we get the majestic approach, a few furious moments of webbed feet slapping on water, then the majestic splashdown.

Erling Haaland and the rest of the Norwegian men's team are paid the same as the women's team. In 2017, they took a voluntary pay cut to allow the women's pay to be increased. The move came from the players' union, not management.

fixed your headline
A hit song on the Billboard 100 charts is termed *$k$-good* if it is _ever_ in a weekly top-$k$, and *$k$-immediate* if it _debuts_ in the top-$k$.


An artist is *$(n,k)$-Olivian* if their $n$ first $k$-good hits are all also $k$-immediate.

*Headline 1.* Olivia Rodrigo is the first $(10,10)$-Olivian woman.
