Prince of pi

Happy Pi Day! From Wikipedia:

Pi Day is a holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.

Pi Approximation Day is held on July 22 (or 22/7 in day/month date format), since the fraction 22⁄7 is a common approximation of π.

Larry Shaw created Pi Day in 1988. The holiday was celebrated at the San Francisco Exploratorium, where Shaw worked as a physicist, with staff and public marching around one of its circular spaces, then consuming fruit pies.

The Exploratorium in San Francisco has Pi Day 2012 programming in celebration of everyone’s favorite math constant.

    I’m partial to Tau day myself. Not for any philosophical or mathematical reason, but because Tau day results in even better discounts 😀
