Math Encounters: "Cracking the Code: How Math Was Used to Decrypt Drivers License Numbers" with Joe Gallian (4:00 pm)

Sometimes, things done just for the sake of curiosity can have interesting applications.  Join Joe Gallian, Professor of Mathematics at the University of Minnesota Duluth, as he shares his story of breaking the codes for drivers license numbers in several states, just for the fun of it, and how he made use of an important problem-solving technique to do so.

Special introduction by mathematician Bob Beals.
