Matthew Hartings is a chemistry professor at American University, and will most likely go down in history for coming up with the absolute best way to teach chemistry concepts to non-college types: using his dogs.

Matthew's hobby is actually training Paige and Dexter, and what better way to make complex ideas like chemical bonds easy to understand than by combining both of his passions? These two would make any college course seem less intimidating, and even better, they're probably easy to bribe with nothing but a pack of Snausages. [Matthew Hartings via BoingBoing]
