Tau Day or Pi Day?

I have just be exposed to the new revolution of Tau. Apparently people believe that Pi is way to confusing when it comes to the unit circle since a whole circle represents 2pi. So Michael Hartl decided to change this and use the Greek letter Tau to represent half of Pi, so one turn around the unit circle is now 1 Tau. I think this would be a fun video to show my students, especially since one of my classes is learning the unit circle, to show them a new perspective on the subject. Even though this new Tau notation is not at all accepted on standardized tests or in college classes, it is an interesting topic to bring up and shows that math can be creative and logical at the same time.
