Surely in theoretical physics, the most common use of
>is in a ket (eg.|ψ>).Crocodile want to eat cactus ?
That cactus is the devil!
Crocodile needs eat cactus to see window
wow that's a big difference (I have no idea what you are talking about)
I think 〉 means a very hungry (or at least large mouthed) crocodile, and > is just a normal one.
smiles and nods, smiles and nods...
No? Not everyone's doing work on quantum systems. Far from it. Most people do not need to use Dirac notation.
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.
