Subject: Re: Calculus

I once heard a speaker at a conference explain calculus this way. He said
that if you are watching a movie, and stop the projector (videotape for you
younger folks), you could look at the frames separately. Look at two that are
consecutive (side by side) and it is difficult to notice any differences in
them. You know there are differences. However, they are so small you cannot
easily see them. Now look at two other frames of the movie, but this time
choose two that are 10 to 20 frames apart. Is it easier to see the
changes from one frame to the other? Now look at the first frame of the
movie, and the last one. They are vastly different, are not they? Although it
was difficult to see the changes when you were looking at the two consecutive
frames, there were changes occurring. That is what calculus does. It looks at
change, and expresses it with numbers and equations.
