A quantum observable is a measurable operator whose corresponding property of the state can be determined by some sequence of physical operations ("observation"), such as submitting the system to various electromagnetic fields and eventually reading a value. In systems governed by classical mechanics, any experimentally observable value can be shown to be given by a real-valued function on the set of all possible system states.

How do expected values of observables depend on the current state?
On pages 835/836 they define observables and the expected value of an observable corresponding to a hermitian linear operator $M$. …
