Happy Pi Day!

Pi Day is coming up this week. The date is 3/14 and happens every year. Some places even offer Pi Day deals. People celebrate it in various ways. Maybe they will make a pie with the pi symbol on top; perhaps they will go out for pizza pie; maybe even participate in pie throwing contests.

Pi Day was founded in 1988 by Larry Shaw, a physicist. Why 3/14? Well, duh – Pi is approximately 3.14159… It also happens that it is the birthday of Albert Einstein. Pi is a number that is used in calculating the circumference of a circle.
