Pie, of course! Before you head out for Spring Break, stop by the Sciences Library to get your free apple pie bites on Friday, March 14 for the celebration.
Think back to your high school geometry class; Pi is the ratio of the circumference of a circle to its diameter. Pi is approximately 3.14159, but has been calculated to over two trillion digits, it goes on infinitely without repeating or becoming a pattern. Science would not exist without Pi. Mathematics, statistics, engineering, geography, geology, computer science, etc. all rely on Pi.
