... The amplitude for a given path ~r(t) is of the form e h̄ S[~r] , where S[~r] is the action functional for the trajectory.† The action functional assigns a number to each path ~r(t) connecting ~r1 to ~r2 . The specific way in which the action assigns numbers to paths depends upon the physics (degrees ...

Galileo stated that if friction were entirely absent, a ball moving horizontally would move forever at the same speed ...
