Pi Day celebrates the mathematical constant 3.14, the ratio of a circle’s circumference to its diameter.
So why celebrate a number? Well, it’s a pretty amazing one. Pi has been known for thousands of years, with references dating to ancient Egypt and within the Old Testament of the Bible. The decimal expansion of pi never repeats; it goes on forever. Pi is also one of the first known irrational numbers. Neat stuff.
Pi Day, not only a day to learn more about the history and application of this number, is used also as an opportunity to raise awareness in, and exploration of mathematics. The day has even earned Congressional recognition.
So in the spirit of embracing my “irrational” side, I present the a “rap battle” between Sir Isaac Newton and Bill Nye the Science Guy with a cameo appearance from astrophysicist Neil deGrasse Tyson. (Check out one of his tweets from earlier today.)
This shows that presentations and videos don’t have to be stodgy to capture the imagination to embrace math (and science, too). Enjoy!
