"Four Tales of Impossibility"

"Nothing is impossible!" It is comforting to believe this greeting card sentiment; it is the American dream. Yet there are impossible things, and it is possible to prove that they are so. In this talk we will look at some of the most famous impossibility theorems—the so-called "problems of antiquity." The ancient Greek geometers and future generations of mathematicians tried and failed to square circles, trisect angles, double cubes, and construct regular polygons using only a compass and straightedge. It took two thousand years to prove conclusively that all four of these are mathematically impossible.

"On Pennies, McNuggets, Polynomials, and How to Help the Government Save Money"

In the 80's, McDonald's restaurants used to sell boxes containing 6, 9 or 20 chicken McNuggets. It was impossible to purchase exactly four or ten nuggets. What other exact numbers of nuggets were impossible to buy? The solution to this question is related to a classical problem in the frontier of number theory and discrete mathematics known as the Diophantine Frobenius Problem.

In this talk we discuss how this famous problem connects the apparently random string of words in the title. Along the way, we will learn about some of its history, applications and generalizations. As an example, we show that it can be used to help the American government not only to save $52.9 million yearly but to also turn a modest profit.
