It’s a thing that I’ve always thought that people over-complicate. It’s just there, the small side with the small number the big side with the big number…
For a while, I’ve seen “<” and “>” as a slanted “=”, which is to say, these numbers are not equal, and the larger side is the larger number and the smaller side is the smaller number.
Works for me, IDK.
But shouldn’t it be 8 < 1 because the eight is heavier and squeezes the bars of the = together?
No, since it’s bigger it stretches the lines apart :)
“How do you know if someone is doing a phd in physics?”
Didn’t know so many people had trouble with this. To me they’re as different as b and d. Never had to think about it
Open end is big space (bigger number). Closed end is smaller space (smaller number).
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.
arguably, it’s |ψ〉, which is not the same as >
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.
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…
