Pi day is a day to celebrate the mathematical importance of the discovery of pi. Pi is a mathematical constant which represents the ratio of a circle's circumference to its diameter, and is commonly approximated as 3.14.
Did you know:
- Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern.
- March 14 is Pi Day and in 1879 on this day, Albert Einstein was born.
- Lu Chao holds the record for knowing the most numbers in pi. He knows 67,890 numbers, which takes him 24 hours and 4 minutes to repeat.
- Pi cannot be expressed as a fraction, but is approximated as 22/7.
How you can celebrate:
1. Create a pi necklace: assign each number 1-10 to a bead color. Place the beads on the string in the order that the appear in the digits of pi.
2. Bake some delicious pies: What better way to celebrate a day named after pi than with its homophone, pie?! Find some of the best recipies for apple, pizza, chocolate oreo mousse, and many other delicious pies here!
3. Pie a friend or teacher: There's no sillier or more personal way to celebrate pi day than taking a pie to the face. Many organizations such as the Indiana University Physics Club have used the occasion as an opportunity to fundraise: simply set a fundraising goal and find someone who is willing to be pied if the goal is met.
4. Discuss the importance of pi and try to solve for pi: Using a circle, measure the circumference and diameter, and see if you are able to prove pi.
