March 14, when written as 3/14, represents the first three digits of pi. It is the ratio of the circumference of a circle to its diameter. To celebrate the world's most famous mathematical constant, enthusiasts around the world embrace their inner nerdiness. They celebrate Pi Day. 

The date also happens to be Einstein's birthday. It inspires a variety of events every year. Last year was the ultimate Pi Day, as adding the year to the date notation, 3/14/15, encompassed even more digits in the sequence. We won't get this much pi again for 100 years.
 
Just why are people crazy about pi? The number is 3 followed by an endless string of random numbers after the decimal point. It is irrational. That means it cannot be expressed through the division of two whole numbers. It is also a transcendental number. That means that it isn't the root of any algebraic number. This irrational and transcendental nature appeals to people. Perhaps it is because pi's continuous flow of digits reflects the unending circle it helps to trace.
 
Pi has held an almost mystical quality to humans throughout time. Its unspoken presence can be felt in the circular ruins of Stonehenge, in the vaulted ceilings of domed Roman temples and in the celestial spheres of Plato and Ptolemy. It has inspired centuries of mathematical puzzles and some of humanity's most iconic artwork. 

People spend years of their lives attempting to memorize its digits. Contests are held to see who knows the most numbers after the decimal. Some people write "piaku."  Those are poems in which the number of letters in each word represents subsequent digits of pi. Other people create complex works of art. They are inspired by the randomness of pi. The list goes on and on, like pi itself.
 
How are you celebrating Pi Day?

    Pie day wouldn't be on the same day because three point two equals to 3\20 so it would be on March 20th.

    If Pi=3.2 then it would be useless to remember and there probably wouldn't be a Pi day because it does not continue with an unknown sequence. If there still was pi day then it wouldn't be on einstein's birthday

    If pie was equal to 3.2, then the celebration date would be different. Instead of march 14 it would be march 2.

    If Pi= 3.2 then there probably wouldn't be a Pi Day because 3.2 does not have a unknown sequence and there would be no point in remembering that digit, also if If there still was Pi Day then it would be on March 2nd, and not on Einstein's Birthday.

    In this article it talks about the celebration of Pi Day. Mentioned in the article is also that it is Einstein's birthday causing an eventful day overall. People get very creative when it comes to celebrating pi. Why do people like the number pi so much is also explained. This is because the number pi cannot be so called expressed through the division of two numbers. Also that it isn't the root for any algebraic number. People spend years in attempt to memorize the numbers of pi. All of this involves civic engagement by getting the public involved in celebrating Pi Day. People are engaged because pi day is in everyone's lives. For example on Pi Day, McDonald's gives you a free apple pie and they sell an abundant of them.

    If pie was 3.2,then the day for pie would be the 2nd,not the 14th.

      It would actually be on the 21st because if you look at the pi numbers 1 is after `4 so if it was 3.2 it would be 3.21 so it would be on the 21st

    We celebrate pi day on March 14th because pi is 3.14. Pi is the ratio of the circumference of a circle to its diameter. I use pi in this formula C=pi x d. It is fun to celebrate pi day.

    If pi =3.2 pie day would be on march 2 and not march 14 and last year would still be the greatest pie day ever.

      It would actually be 3.21 because one comes after the 14 so I would be on the 21st of March.
