@Fil Albuquerque,
Thanks for trying to help, but your link only succeeds in twisting my already simple mind into more pretzels.

You see, I studied Accounting in college, and physics was way beyond my iq level. I can still remember, 2+2=4. A close friend of ours is a physicist, and he authored a book on the subject, and gave us a copy. It all looked like Greek to me! No comprende.
