What do you think "integrate" means?

Just so's you know, I did write:
*" And for some reason, the path taken by the object through space will integrate
this difference across the distance between any two points "*

But never doubt the capacity of some group of experts, when challenged to make
sense of themselves, to congeal around some picky point of language. And yes,
this is me, saying that.(};-)]
And why do we keep calling it by it/s cult name, rather than calling it what it
is? The difference between the energy of a moving object conveyed by its
velocity and that conveyed by its position in a field. If you want jargon, why
not just call it Ev-Ep.
And yet, nobody tackles the basic question. Why on earth would E in the v-Ep
be something that every moving object in the universe tries to accomplish.

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.

Frank,
Thanks SO MUCH for forwarding this to me. To any other defrocked
english majors on Friam, who have listened to these guys blather on about
LaGrangians for all these years, I highly, HIGHLY recommend the video. Pretty
short, AND, you might possibly, conceivably understand Steve Guerin when you
get to the end. Yeah. Really.
Nick
