Quantum mechanics and path integrals
... Returning to the path integral (1.1), applying the basic idea of the method of steepest descent, one would expect that for small h̄, the dominant contribution to the path integral will come from functions x(t) such that δS/δx = 0, and other contributions should be, comparatively, exponentially suppr ...

... The total force on all the particles is a sum of the total external force on the body and the sum of internal forces between particles—but these internal forces come in equal and opposite pairs, from Newton’s Third Law, and therefore add to zero. The bottom line, then, is that the rate of change of ...
