This post is really for math geeks only. If you aren't ready to play with a little calculus and a little probability, don't bother watching the video. Today is π Day, March 14th. March is, of course, the third month and Pi or π is a number that starts with 3.14. Thus the silly pretense for sharing a cool video about numbers.
As someone pointed out in the YouTube comments, the length of this is 2π. Geeky!
π = τ/2
ReplyDeleteτ = 6.283.. a far more elegant number.
Tau day is June 28.
