Today is Pi Day, an unofficial day of recognition honoring the mathematical constant Pi, the ratio of a circle’s circumference to its diameter — and you don’t need to be a mathematician to take part. The ratio Pi is an irrational number, which will continue infinitely without repeating, and has been calculated to over one trillion digits. Pi Day is celebrated worldwide every year on March 14 since 3, 1, and 4 are the first three digits of Pi. How exactly does one celebrate Pi Day? Eat some cherry pie, drink some $3.14 beer, and then maybe sit down for a minute and try to wrap your head around how this trillion-digit ratio dictates our entire mathematical universe.
