Charles Moore.Who better than an expert mathematician to help celebrate the 14th day of the third month of the year, unofficially known as Pi Day for the numeric expression it shares with the the ratio of the circumference of any circle to the diameter of that circle: 3.14.

Recorded using a Looking Glass studio set up, Charles Moore, chair of the Department of Mathematics and Statistics, provides a brief overview of the scientific significance of pi. The video was shared broadly on WSU’s social media channels on Pi Day.

“Pi is both troublesome and mysterious,” Moore explains. “A circle is something very simple and beautiful, yet the number pi is not.”
