My animated maths video for this year* is about a mathematical model for traffic flow - and how to visualise the method of characteristics to solve PDEs.

As usual, I've entered it in the Summer of Math Exposition #SoME4, as that hopefully will generate some views and make these things worth my time.

*There may or may not be one next year. There certainly won't be another one this year.

Waves, not cars - modelling traffic as a fluid

I'm trying to watch some of the cool #some4 videos people have made (summer of math exposition)
About half have AI generated thumbnails.

Some videos *on* generative models say "oh, these generative models are like a creative artist" - Interesting idea. Counterpoint, go fuck yourself, fuck AI images, and fuck AI music.

I don't care if there's videos *about* AI. there is fun math there, despite the hype. But seeing business majors infect another one of my hobbies is really disheartening.

My entry for this year's Summer of Math Exposition #SoME4

The challenge this time was to create something that can be used "in the classroom" and it will be subsequently judged by teachers in this regard during peer-review.

Not sure how well the idea of "try to do induction exercises without induction" works for this, but we'll see.

Dutch organizations, individuals quit X on day of Trump's inauguration

Seventeen organizations and some 4,000 individuals are leaving the social media platform X, formerly known as Twitter, on Monday. They are joining #DetoX, an initiative by DeGoedeZaak and Stem op een Vrouw. With this action, the social organizations want to make a statement “against online hate, disinformation, and political interference.”
