To every observable in classical mechanics there corresponds a linear, Hermitian operator in quantum mechanics. We have in part already discussed this postulate in chapter 22, albeit we didn’t call it as such. This postulate is necessary if we require the expectation value of an operator \(\hat{A}\) to be real, as it should be.
