I was not trying to impress you. It was my last resort to make you think. I am not sure I'll bother explaining anything to you ever again.
Don't feel that way! This board needs more thinker makerer people (where would we be without college graduate "even C students can become Preznit" Dubya Bush). (Gotta love the guy...he is even better than Dan Quaile.)
Honestly, your posts and thinking are great!!! You and Guiness are just splitting hairs, that is all. I loved the analogies and examples, just so ya know.
All of the asymptote talk got me thinking of an example that my high school chemistry teacher used (20 years ago, mind you). If you have a dump truck full of sand and you add or subtract a teaspoon, is anyone going to care? Will it make a difference on any scale that you can put the truck on? If the teaspoon of sand was put on your lunch, would you notice?
The last one is mine, just to accentuate Relativity. Albert Einstin defined relativity like this:
"Put your hand on a hot stove for a minute, it seems like an hour. Sit with a pretty girl for an hour, it seems like a minute. That's Relativity."
I don't remember exactly how Kelly Bundy defined it, but you really don't want to know...
