Happy Pi day

Today is march 14, also known as Pi-day. Some people thinks it is the most irrational day of the year! Interestingly, it is also Albert Einstein's Birthday.

A brief math refresher: Pi, a simple concept, the relationship between a circle's circumference and diameter: Multiply the diameter by pi — 3.14159, to use a crude approximation that would make many of the people in this story blanch — and you get the circumference.
It is is about a curious group of people with an almost religious zeal for a mind-numbing string of numbers. Actually one number, made up of a chain that is known — so far — to be more than one trillion digits long. They are the acolytes of the church of pi.

When I read the stories about "Pi-day" fans, I am so glad that I am not a Pi-fan :
