使问题从一种状态变化为另一种状态的手段称为操作符或算符。算符在单独存在时是没有什么意义。操作符可为走步、过程、规则、数学算子、运算符号或逻辑符号等。

So here I've written for the hydrogen atom that deceptively simple form of the Schrodinger equation, where we don't actually write out the Hamiltonian operator, but you remember that's a series of second derivatives, so we have a differential equation that were actually dealing with.
