Thank you. That's a hard concept for most of us to get a handle on......especially those of us mathematically challenged.

I wish I could find the post. It was so interesting. Or that whole thread to be exact. There were some folks on there who worked at NASA. One retired and one current. (At Kennedy.) And a few real science people, math guys, and astronomers. And some very well versed space shuttle guys.
