Surely in theoretical physics, the most common use of > is in a ket (eg. |ψ>).

No? Not everyone's doing work on quantum systems. Far from it. Most people do not need to use Dirac notation.

[–] [email protected] 3 points 3 months ago

I guess not. Its just that when I hear 'theoretical physics' I immediately think of particle physics (and related fields). I have this idea that in most branches of physics people just say the topic, eg. astronomy, material sciences, or whatever; and don't usually specify whether they are doing theoretical work or experimental/empirical work. But in particle physics ... my impression is that people are more likely to specify. Anyway, that's just my own bias I guess.

arguably, it's |ψ〉, which is not the same as >

[–] [email protected] 7 points 3 months ago (2 children)

wow that's a big difference (I have no idea what you are talking about)

It is just a notation for linear algebra and linear operators on complex vector spaces together with their dual space both in the finite-dimensional and infinite-dimensional case. Really quite simple stuff actually...

smiles and nods, smiles and nods...

I think 〉 means a very hungry (or at least large mouthed) crocodile, and > is just a normal one.

Crocodile want to eat cactus ?

Crocodile needs eat cactus to see window
