Re: [FRIAM] Watch "The Most Important Idea in Physics: The Principle of Least Action - Ask a Spaceman!" on YouTube
So the difference is at a positive max when the ball hits the ground and at a negative maximum when the ball reaches its highest altitude? So how am I to understand positive and negative?vectors? Instantaneious Action is at a minimum when the two terms are equal? I have no intuitive sense of what is going on here. But thanks for trying, Frank.

Re: [FRIAM] Watch "The Most Important Idea in Physics: The Principle of Least Action - Ask a Spaceman!" on YouTube
Hi Frank and all, Ok, so the Action of an object is the diffrence between its kinetic and its potential energy. (Have I got the grammar right?) Since mass appears in both terms, the Action is the mass of the object times the difference between half it's squared velocity and it's height off the surface. So, a mass can have two kinds of energy, that imputed to it because of its motion, and that imputed to it because of its position [with respect to other objects, specifically the earth, in this case]. And for some reason, the path taken by the object through space will integrate this difference accross the distance between any two points. Ok, do I have that right? Or is this just another example of the dangers of teaching defrocked english majors a teensy bit of physics? Now, we are still in the realm of classical physics. So, there is still a chance that non-mathematical intuitions might apply, right? Does anyone on the list have an intuition for why the difference between the energy of motion and the energy of position should be what guides all motion in the universe?

Frank, Thanks SO MUCH for forwarding this to me.
