ABSTRACT
Many important quantum observables, e.g., angular momentum, have their origin in corresponding classical observables. Postulate 26.1(OV) does not tell us how to find the operators to describe these observables. We can tackle this problem by formulating a process of quantisation to establish the operators for the corresponding quantum observables. Before we can formulate a quantisation process we must choose an appropriate description of classical observables. This is done in the following section.
