Work Step by Step
Strictly speaking, the correspondence principle was proposed for the overlap between quantum physics and classical physics, so it doesn't apply to macroscopic events. However, we can extend its applicability, and broaden the definition. In any field of knowledge, it is logical that two theories should give matching results in the region where their domains overlap. For example, if theory A predicts how males will behave in a given situation, and theory B predicts how any human will behave in a given situation, the theories should correspond when applied to a group of males. This is discussed on page 611.
