Yep, garbage.
Please, read what I wrote more carefully. You have missed the point I made (and I dare to say, deliberately).
And, I don't need Lama to tell me what to do and how to do it.
In the course of my scientific education over the years I DID go through that (and many, many more) proofs - this is how math is supposed to be learned.
So, I don't have the BELIEF - I have KNOWLEDGE. And, as Craig said, if I forgot something, I can ALWAYS go through the process again.
Brian, I did advise you before, and I do it now, again: please study in more details the subject before you come up with statements like this...
This is science forum, where people can learn a lot.. if they really want to.
