Bill,
You must remember the Slide Rule? I immediately thought of that as I read your post. The length of the slide rule is life. It is full of unsolven formulas and mysteries. The slide rule has a clear piece of plastic that one moves over it. That cleat plastic "window" has a thin black line inscribed in it.
When the pieces of that mathematical wonder are lined-up in the desired position, this is where you will find your answer. The rule is lifem the clear plastic is a window to "near" times, and the hairline is NOW, and that is where the answer lies. Look anyplace else and one is lost in the universe.
