Pomm and Timmer

James "Pomm" Pommersheim and Tim "Timmer" Marks are the original and current instructors of Number Theory. Since the early 90's, they have brought joy and laughter into the hearts of many CTYers. Their teaching style is known as the Diophantine method. They teach the class through a series of skits in which famous mathematicians illustrate examples of their discoveries. Their involvement with CTY goes back to the 80's, when they were students at St. Mary's. Today, Timmer is a part of Staff American Pie tradition as during the line "And while Lenin read a book on Marx" the staff all say "Tim Marks!" Pomm and Timmer, along with Tortoise and Dr. Ted, have also reached their fame outside of Number Theory with their famous Barbershop Quartet, an act they've put on at the Staff Talent Show up to and including 2005, Dr. Ted's last year. The most impressive thing about them however, is how many shirts they have from Number Theory classes past. They wear a different one nearly every day of the session.

The two, the only, Pomm and Timmer!
