Nearly 90 students, faculty, staff and visitors enjoyed hearing two talks as part of North Central’s Inaugural Pi Mu Epsilon Prime Time Mathematics Colloquium on May 25. The first talk, titled “The Mathematics of Google,” was presented by Shaun Cox, software engineer with Google. Following his talk, students and faculty were initiated into the Pi Mu Epsilon Honor Society.

The second talk of the day, “The Mathematical Theory of Knots,” was presented by four North Central College students: Donglun Liu ’13, majoring in mathematics, economics and actuarial science; Steven Mackey ’13, majoring in political science; Tyler Schroeder ’13, majoring in mathematics; and Kyle Thomas ’13, majoring in computer science. They presented results of their ongoing research with Neil R. Nicholson, assistant professor of mathematics.

With North Central College officially becoming a Pi Mu Epsilon National Mathematics Honor Society chapter on Honors Day on May 17, this talk was the first in an ongoing series of mathematics-related talks.
