Scotty,

What you "think" or "are sure of", in no way proves a fact. Bob gives  
us something really interesting to think about. A rough skin may make  
a plane go faster! Remember when we found out that a blunt nose on a  
submarine made it go faster? No one would have guessed. More new  
discoveries are made by accident then by over confidence.

I asked a professor once, if there were an experiment proving that  
electrons exhibited a gravitational force. The professor laughed.  
Trying to use proof by intimidation. It didn't work. To this day it  
has never been proven that electrons exhibit a gravitational force.  
There is a problem with General Relativity and this train of thought.  
If anyone would like to discuss it, please give me a call.

Back to Bob's point. Does anyone else have figures on rough skin vs  
smooth?

Sincerely,
Lorn
