*Math Encounters*: "Tag Deal: Discrete Chaos in a Deck of Cards"

**featuring Barry Cipra**

**Wednesday, January 12 ****at 4:00 pm ET (New York)**

**(online)**

Insanity, it's sometimes said, is doing the same thing over and over and expecting different results. Mathematics, it might be said, often involves doing the same thing over and over and actually achieving different results. Join freelance mathematics writer Barry Cipra for some mathematical insanity with Tag Deal, a game of unpredictable repetition.

Special introduction by Laura Helmuth, *Scientific American *Editor-in-Chief.
