But math is a different discipline and why I quoted 'accepted' instead of 'truth'. >> After all a premise is a premise.

Well, this is usenet. Just because someone can type doesn't mean they are here for anything else but to 'play the man'. All it takes is for their high school teacher to miss represent 'laws of physics' and they think they know it all. DanB.

Why are you using them?
