## Days of March

March 14, 2012 by orlandfreelibrary

March has something interesting every day it seems. Tomorrow is March 15th, the Roman “Ides of March” when Julius Caesar was assassinated by a conspiracy of men who did not want the Roman Republic ruled by an emperor. Two days later, on March 17th, is St. Patrick’s Day, when everyone is at least a wee bit Irish.

But today is the 14th of March, and that makes today a special day too. It is Pi Day, a day that celebrates the important number know as “pi.” Pi is a mathematical constant that represents the ratio between the circumference of a circle and its diameter. The value of pi is approximately equal to 3.14, so 3/14 is a fitting day to commemorate a number that is used in many calculations in math, engineering, and science.

A pi pie.

Pi Day was invented in 1988 by Larry Shaw, a physicist who worked at the Exploratorium in San Francisco. It is still celebrated at the Exploratorium with marching in a circle and eating (what else?) pie.

Not only that, but March 14th is also the birthday of scientist and all-around smart guy Albert Einstein. So say “Happy Birthday” to Einstein, do a little math, and have some pie!
