US Thanksgiving really is a great time to visit Paris. I have twice - 2012 and 2022. Cheeseburgers and whiskey with an ER doc and his auto mechanic pal 2011, five course cooked up/purchased in my AirBnB 2022.

These dining options look like fun too though.

Lots more to consider, like just stop using Meta but why leave if I can stay and grind its gears.

Very happy with this set of videos. Even if you don't need a beginner python tutorial you may find the presentation methods used of interest. I am able to read the code they are explaining - on my phone.

Filing this under: man, I love graded rings
Illustration on engineering paper of a kitty in a little outfit holding the monomial 7x^2 and looking quizzically at some boxes labeled A0, A1,A2,A3. There are a couple of monomials laying to the side and it reads ‘sorting my monomials into little boxes’

My 6yo asked me this morning:

"If 0 + 0 = 1, would 8 times 0 be 4?"

I wrote a blog post about it.

New geometrical drawing of mine, colored with watercolors.

Spins in quantum mechanics and stereographic projection. "Where does this weird factor 1/2 come from"

#SciArt #MathArt #PhysicsArt

Inspired by Roger Penrose! My 2021 blog post about the math: elkement.art/2021/10/26/s...
Summary in ALT!
Geometrical construction colored with watercolors and annotated with mathematical formulae: Spin in quantum mechanics related to stereographic projection. By elkement 2025. The spin is built from an up and a down component. If you visualize it as an arrow pointing in a certain direction, you can project down the point where the spin punctures the sphere. The image point In the equatorial plane can be interpreted as the ratio of the "amounts" of up and down component (This is not exact terminology.) Playing with the geometry, half of the inclination angle theta of the original arrow shows up again when looking at the projection in the plane. This factor one half is what a lot of weirdness of spins can be traced back to (like: "You need two full rotations to get back to the original state").

Well now, would you look at that?

A massive study of NEARLY 300,000 people in the United States found that receiving an updated 2024-2025 mRNA COVID-19 vaccine REDUCED people’s risk of severe disease AND death in ALL age groups, REGARDLESS of immunity from prior infection or vaccination.

Do you take your work home with you? It's kinda hard to avoid if you are a mathematician. The maths just follows you wherever you go.

You all know that I think the world of Mr Perlstein's magisterial 4 Vol. history of American conservatism which as a whole describes, well, how America got this way. Excited to see he's making the project explicit. Here he is on the late VP Cheney:
