Which one do you prefer? Tau or Pi?
"In what might be one of the nerdiest debates of all time, mathematicians are divided about the use of Pi (which starts 3.14) over Tau (which starts 6.28) in geometry. The ongoing debate about Pi vs. Tau is colored by the popularity of Pi, which has its own “day” celebrated on 3/14, most often with the consumption of pies. But while Tau might not have any baked goods to offer, today (6/28) is its turn in the spotlight."
