Happy Pi day folks! Math teachers, students and scientists are celebrating Pi Day today.
Pi is a Greek letter and the symbol used for the ratio of the circumference of a circle to its diameter. It is a number with no end that starts with the digits 3.14159. It has been carried out by more than a trillion digits so far, as determined by computers, but will continue infinitely without repeating.
PiDay.org states that it is celebrated on March 14 because of the first three digits of the number, 3.14. In celebration and from a musician’s perspective, here is GIZMODO’s video of what Pi would sound like if musical notes were translated into numbers.
