Yuck a theoretical physicist ;-)
Why do you guys always have to calculate in dimensionless units *brrr*
Don't tell me I know, just hate to use them. :-)

Richard, you fail to see James point, sure you can go down to further
and further levels of explanations, but you would always end up at one
point where you can explain anymore, even if it would be the question
where do the scientific laws come from. This does certainly not prove
the existance of god, but it shows that science cannot answer the
ultimate question. And those questions have to be either answered by
philosophy or religion, or stay unanswered.

Cheers
Jochen
