Abstract
Classically, the evolution of a physical system is described by a unique trajectory in an appropriate phase space. Ehrenfest’s theorem suggests the possibility of similar description in terms of the expected values of the position and momentum observables. This connection between the classical and quantum descriptions is often useful but has a limited range of applicability in deducing the behaviour of physical systems. The source of the discrepancy is investigated providing an insight into the basic differences between the classical and quantum descriptions.
