Google Doodle: It’s Pi Day
Posted on 14. Mar, 2010 by dimaks in News, Web
Today’s Google Doodle is on Pi Day – virtually the birthday of our mysterious mathematical variable Pi, which goes by the symbol Ï€ with rounded off value of 3.14 or sometimes 3.1416.
Pi Day and Pi Approximation Day are two holidays held to celebrate the mathematical constant π (pi) (in the mm/dd date notation: 3/14); since 3, 1 and 4 are the first three digits of π. March 14 is also the birthday of Albert Einstein and the two events are sometimes celebrated together.
Pi Approximation Day is observed on July 22, because of Archimedes’ popular approximation of Ï€ being 22/7. However, this may be considered misleading, as all cited dates are “approximation days” (as Ï€ is an irrational number) and 22/7 is actually a closer approximation of Ï€ than 3.14. Typically, March 14 is more popular for countries using the month/day format (22/7 being an impossible date in this format), and the 22nd of July is more popular for countries using the day/month format (since 3/14 and 31/4 are impossible dates in this format).
Honestly, I never knew that there is such a thing as Pi day until I bumped into Google Doodle today. I thought that π is a mere constant in our mathematical formulas.
By the way, Larry Shaw founded the Pi Day. Shaw is now a retired physicist at the Exploratorium in San Francisco, CA.
