Bailey and Jonathan Browein explore whether pi’s digits are statistically random. Powerful modern computers can help mathematicians answer questions that still linger about the number using analytics software. While the numbers never repeat in pi, Bailey and Browein go searching for patterns.

Listen to some Pi music

Math and music go well together, so there are a number of pi-related music videos. Some are good, some are not so great. We liked this one, where Michael Blake uses various instruments to “play” the number pi. He’s assigned different notes to the numerals and plays the notes in the order of pi. Technically, that could be the song that never ends…

Defend Pi!

Pi lovers, take notice: On this day to celebrate pi, there are some haters out there. Some math enthusiasts have undertaken a movement to use tau instead of pi in mathematical equations. Tau equals 2 pi, which some argue is a more logical way to measure a circle. For an explanation, watch the above video. And if you do defect to Tau instead of pi, we’ll help you celebrate Tau Day too (6/28).

Get ready for next year

While Pi Day is an official national holiday, as ordained by the U.S. Congress in 2009, next year’s Pi Day on March 14, 2015 will be extra special because the date (3/14/15) has the first five digits of pi, not just the first three like most other pi days. So, enjoy today, but get ready for a big celebration next year.
