Grr...Math, yuck.  I'm glad to say that I have not had a math class in years.  No, Dr. Sauron was a Constitutional History/Ethnic History and Studies professor.  The reason why I dropped his class was not so much because of his disturbing and morbid weirdness, but rather to prevent myself from doing three research papers in one semester.  That's something I would prefer not to have to try.  Even though I probably will at some point.  
Hmm...looks like Saruman, walks with a long staff...  
I'd say that if he speaks to strange round black objects that he has tucked away in his office, and is served by little goblin-like creatures that run around tearing down trees and breeding bigger goblin-like creatures he's probably the guy.      
 
  
I'd recommend giving him a new recipe for whipping up a new batch of Uruk-hai.  He might give you an A in the class.
