To model the climate we need equations, using trad physics, that are so computationally expensive they require large data centers like DOE traditionally builds for even small scale modeling. AI can help provide accurate proxies for those equations with lower cost. Giving us better predictions.

I dunno. Maybe it's just me. But I think that if I were in charge of naming the part of atmospheric and oceanic modeling that solved the full equations of fluid motion, especially involving climate change modeling that predicted everything is gonna get hotter, I wouldn't name it "MOLOCH."

"Inside this DAG is another DAG curled up really small!"
As a physicist I once sat through an entire seminar thinking a "disease model" was a bunch of equations, only to realise in the final slide that it was an actual mouse!

Today in #QM1 we went back to being like a real physics class: solving differential equations. In particular, the Schrödinger equation for the simple harmonic oscillator. Some tricks get it into a form where some heroic 19th-century mathematician surely solved it, but we're doing it ourselves.

I‘m so grateful to the advance readers like @ruha9.bsky.social who spent time with my book and understood the work I hoped it would do. The principled creative work that Ruha does is an incredible model 🖖🏽

Et demain ? Et si notre Big Bang n’était qu’un récit, le plus moderne à ce jour, du mythe des origines ? Chaque culture, de la Chine au Mexique, a cherché à dire l’origine du monde avec ses mots. Nos équations prolongent ces mythes : elles traduisent la même quête humaine du sens et du commencement

According to the equations that govern black holes, the larger one of these cosmic behemoths is the lower its average density – given that the universe contains a lot of relatively empty space, could the whole cosmos be a black hole?
Is the universe really one big black hole?

Sometimes being a demographer makes me too pedantic even for myself. Sorry for my emails/papers/equations/things I say, everybody. Not sure there's any way around it.

PSA: if you're writing a numerical simulation paper, please add the initial and boundary conditions as clear separate equations or at least bullet point sentences. It is incredibly hard to decipher them if they're written in vague language inside a paragraph somewhere.

I love teaching the foundational papers, but this one has made me a bit insane on revisiting it in depth. Cholera cases are "mu", but then lagged cases are "chol", but there's also a case index "I" that is never defined in the paper or supplement; CHL is in fact "chlorophyll" and NOT cholera somehow

The reason the speed of light shows up in so many random physics equations (e.g. E=mc2) is because it's not just "the speed light travels at" or "the maximum speed possible", it is a constant value describing the relationship between two dimensional quantities - that of space and that of time.

My physics professor had a prop for every concept on the syllabus.
Understanding motion equations is a hell of a lot easier if you see them demonstrated in front of you.
If Dr. Keller wasn't the best professor I ever had, he was in the top two.

Even if and when such technology exists, we should not at all be surprised to pay crewed combatant prices for uncrewed systems. Ultimately, the value meatbags bring to operational equations in naval warfare remain somewhat underappreciated. We do not crew ships to enjoy a cruise.

Robin Wilson's second talk on the equations that make mathematics stars the man whose work was studied in universities and schools for over 2000 years. Apparently Lewis Carroll for one was miffed when alternatives were used.
