Today is March 14th. To most people, it is just an ordinary day...but to the geeky among us (like me), it's PI DAY (3/14)! (Coincidentally, it's also Albert Einstein's birthday!) Yes, this annual celebration was established twenty-two years ago at the Exploratorium science museum in San Francisco in honor of the never-ending number pi. Pi got its name from the Greek word for perimeter. Pi is an irrational number, meaning its value cannot be expressed as a fraction, and its decimal form is a never ending number that never repeats. Most of us know it is used in geometry, mathematics, science and engineering, and only know it to a few numbers: 3.14159265. The first person ever to find the 3.14 number for pi was Archimedes in 250 B.C. The farthest that pi has ever been expanded has been out to the five trillionth digit! In honor of Pi Day, we made a pizza pie with a pi symbol made out of pepperoni. Yum! Tasty pi!

And a Happy Pi Day to you too, Wyatt! I had absolutely NO idea that such a day even existed. The first music video is truly amazing. Thank you for sharing with those of us who are clueless! I loved your Pi Pie!
