The Emergence of Classical Physics
Quantum physics is nothing like classical physics and it is probably not an exaggeration to say that we just get used to quantum physics — without really understanding it — as we learn more about it! There are several conceptual and technical problems involved in taking the classical limit of a quantum mechanical description. We will not worry too much about the conceptual issues — interesting though they are — but will instead concentrate on one technical issue in this chapter.
