aliensalmon 27 Posted March 14 Report Share Posted March 14 3/14 or March 14 is Pi Day! (In Europe, 22 July, or 22/7, is Pi Approximation Day.)How many digits of Pi have you memorized? I have memorized 11 digits of pi in Base-Ten: 3.1415926535. I believe that's enough precision to estimate the circumference of a sphere the size of Earth (give or take a few molecules).
