Paul Zeitz End of Semester Colloquium: A Revamp of the Second Meanest Math Question in the 20th Century
  • Abstract: In 1999, a couple of mean-spirited math contest creators came up with a problem designed to trip up everyone. But it has a really fun solution that combines geometry, probability, combinatorics, and science fiction.

Title: Cardano and the cubic 

Abstract: You all know the quadratic formula for the solutions to a quadratic equation. What you may not know is that there is a formula for the solutions to a cubic equation (and also for a quartic equation), due to the Italian mathematicians Tartaglia, Cardano, and Ferraro. I will talk about these formulas, as well as the amazing human story of professional jealousy and intrigue. We will also learn how and why mathematicians became comfortable with 'imaginary' numbers.
