SLIDESHOW: Pi Celebration

Walsh Middle School educator Sarah Guernsey asked students, staff, and Framingham families to take selfies on March 14 to celebrate National Pi Day.

If possible, individuals were asked to capture the first 10 digits of Pi - 3.141592653 or mark March 14, 2015 at 9:26.53 a.m.

This mathematical number will not happen again in time for another 100 years.

Many of the photos submitted are included in this report. The photos were submitted to Patch by Walsh Middle.

In 2009, the U.S. House of Representatives declared March 14 (3.14) to be National Pi Day, to celebrate the importance of math, science, and education in our lives, while sparking interest in learning.

Pi is a mathematical constant, the ratio of a circle’s circumference to its diameter. Being an irrational number, π cannot be expressed exactly as a common fraction,so its decimal representation never ends and never settles into a permanent repeating pattern.
