Idle Theory: Least Action Principles Principle is indeed one of the greatest generalizations in all physical science, although not fully appreciated until the advent of quantum mechanics in the present century. Maupertuis arrived at this principle from a feeling that the very perfection of the...A brief review of the mathematics and physics involved in the principle of least action.
