On March 14, NASA will join schools, students and science centers across the U.S. as they celebrate one of the most well known and beloved numbers: pi. Used throughout the STEM world – especially for space exploration! – pi is the number that results from dividing the circumference of any circle by its diameter. Pi can be and often is rounded to 3.14 (even though its decimals never end), which is why 3/14 has been designated National Pi Day.
