Abstract:

Pi is one of the most famous (and important) numbers in all of mathematics. It is defined in terms of circles, but we are never told what size circle to use. How do we know that we wonâ€™t get different values of pi if we draw circles of different sizes? In the real world, it turns out that if you draw circles big enough you will get different values for pi! In this interactive presentation we will discuss the historical definition of pi, draw lots of circles where we get different values for pi, run into real trouble when we imagine circles around black holes, and then (hopefully) restore all faith in the constancy of pi. Come celebrate pi day this March 14 with OSU math fanatic, Sarah Hagen. Absolutely no math background required. Pie will be served!
