Happy Pi Day! Celebrating the Never-Ending Pi | #k12 #onlinelearning

Happy Pi Day! Sorry, it’s not pizza or fruit pie. Although, you can have a slice of those to celebrate. Today, we’re celebrating this kind of pi, π.

Physicist Larry Shaw created Pi Day in 1988, and it became an official national holiday in 2009. Shaw chose to celebrate pi on March 14 because of its first three digits, 3.14, and it also happens to be Albert Einstein’s birthday.

Pi is a mathematical constant—it’s the ratio of any circle’s circumference to its diameter. The first recorded discovery of pi dates back to 250 B.C. Greek mathematician Archimedes used a geometric approach to calculate the first few numbers of pi; he drew hexagons inside a circle until he reached a 96-sided polygon!

Pi is never-ending, but thanks to technology, we’ve been able to calculate more than 50 trillion digits after the decimal point. That’s a lot of pi! How many digits can you list?
