about the significance of commutivity

ShadeTreePhys

can anyone put this into a practical use or just formulas for the sake of formulas? just trying to figure out peoples interest in this if not to develop new ideas or fix what is broken.

Two dimensions? Which dimension are you leaving out? Does it matter?
Hi ShadeTreePhys. I'm just trying to understand quantum mechanics, with no practical application in mind. I'm not trying to develop new ideas, and I don't assume that anything about QM is broken.

totaly cool. i love seeking the know just to know. qm by it's self is not broken. the ref was to the lack of compatibility with the classical.

Common! Look at the operators. If we leave out the z dimension then Lz is the only one of the three operators that makes any sense. It uses x and y and their derivatives, and describes rotations in the x,y plane.

Oh, OK. I thought you were using spherical coordinates.
