If there are fewer coffee drinkers than there are cups of coffee, then at least one coffee drinker must have at least two cups of coffee. Have your cups from this educational mug - showing the famous Pigeonhole Principle in action. There are five pigeonholes, just enough for Euclid, Fermat, Euler, and Gauss - and for the Bernoullis (Johann, Jacob, and Daniel) to squeeze in too.
Dishwasher-safe and perfect for everyday use!
