Application to Quantum Mechanics

If Rotation does not depend explicitely on time, and the rotation operator is

R=1+J_{z}d\theta

,

then, $J_{z}$ does not depend explicitely on time. Why is it necessary to go through all the commutator computations? —Thurth (talk) 06:44, 24 March 2009 (UTC)[reply]

Conformal invariance

Is rotational invariance related to conformal invariance? Article doesn't say.
