I appreciate your input and the effort to help me understand, but I don't.
Sorry, wish I could be of more help
You and some others seem to, or you're not letting not understanding bother you.
You call yourself the Average Clod, but I think you must be a professor of physics...
Why thank you Tom, but I'm a very ordinary old man, only a couple of physics courses to recall

As I had mentioned, I can't see how math is needed here
