An excellent intro to advanced linear algebra by Teo Bancha. Goes right upto lie groups, random matrices and curved space-times.

sometimes physics gets so hard it makes me sob.

I genuinely wonder how many years it took for Wald to develop the level of understanding he has today.

RT @LimYenKheng: *reading a paper published in 1930*."As early as 1911".Bro that was just 19 years ago for you 😭. [R.C. Tolman, "On the wei….

Such a goated eqn. 🫡

What do y'all think about twistors?.

got my paper accepted in PhysRevD 🥳.

I had no idea that Lev Landau also independently derived the Raychaudhuri equation, what a guy 🫡.

RT @cosmicfibretion: No, your AI is not going to discover new physics. You have to go out and make precision measurements for that.

all these ai models don't even know basic perturbation theory dawg 😭.

"When I meet God, I am going to ask him two questions: Why relativity? And why turbulence? I really believe he will have an answer for the first.” . — Werner Heisenberg.

what's the deal with quantum reference frames?.

soft graviton theorem implies the existence of hard gravitons.

one reason why gravity is so different from other interactions is that it breeds singularities, it is remarkable that general relativity predicts its very own downfall.

RT @miniapeur:

this goes hard.

I think I will always love string theory, even if we fail to test its predictions in the future, simply because of its deep mathematical consistency. There is a "kick" in doing its math.
