WebQuantum mechanically, all four quantities are operators. Since the product of two operators is an operator, and the diﬁerence of operators is another operator, we expect the components of angular momentum to be operators. In other words, quantum mechanically L x = YP z ¡ZP y; L y = ZP x ¡XP z; L z = XP y ¡YP x: These are the components.
