Have a happy Pi day. 22 over 7. Or 3.141592…. ? I’m not sure. An important mathematical concept that most people represent with a slice of Pie. Pi is the 16th letter of the Greek Alphabet. Pi is an infinite and irrational number I think? One episode of Star Trek had an out of control computer set to calculate the figure and was defeated because it was an impossible task. I just did a doodle based on the letter. Not exactly exciting sorry x
