Pi Day Celebrated Across The Nation

Pi Day is the celebration of the ratio of a circle’s circumference to it diameter (3.14), which fittingly takes place on March 14.

The irrational number that’s celebrated, while shortened to 3.14, could go on indefinitely without a repeating pattern of integers, according to PiDay.org. The math holiday, established not too long ago in 1988, has become a favorite for foodies as well as math lovers. On the 25th Pi Day, just like on the first that was founded by Larry Shaw (pictured above) in San Francisco, people celebrated with pies.

Some people chose pizza pies, while others chose dessert pies – regardless, food played a large part. At Caltech, the students were treated to a variety of fruit pies just before 2 a.m., reported The Los Angeles Times. Maragaret Lee, a Caltech student, took her celebration a step further in honoring the number. Along with a few other students, she created a paper chain where each color represented a number. The chain ended up at 15,000 digits of pi – a lot, but far less than the ten trillion digits mathematicians have calculated.

First Slice Pie Café in Chicago gave out free slices of pie at 3:14 p.m., and Your Pie’s franchises in the Southeast United States sold pizza pies for $3.14, according to Time. In Milwaukee, there was a 3.14-mile bike ride that followed a pie feast. There’s also this, which is pretty mind-blowing.

So why is pi called pi? In 1706, Welsh mathematician William Jones dubbed it thus because pi is the first letter in the Greek word for perimeter – perimitros.
