Meet Pi Day founder Larry Shaw, and join hosts Ron Hipschman and Lori Lambertson to find out what’s so special about pi—the irrational number that results from dividing the circumference of a circle by its diameter. Learn the history of pi and how pi is calculated, be entertained by pi limericks, and see a cool pi demo. Pie.
