It’s Pi Day, the day we celebrate the mathematical constant π. This day was chosen since today’s date expressed numerically (in US format) matches the number’s first digits, 3.14. Pi represents the ratio of a circle’s circumference to its diameter. It can be used to compute the area and circumference of a circle, such as the crop patterns we"re looking at here in Colorado. (Who said math wasn"t useful in the real world?) Many towns, schools, and museums mark the day with festivities based around mathematics and, of course, serving pie. We can’t think of a more delicious way to study geometry.
