Pi Day! March 14! The first time i heard those words, I said, “Come Again! You must mean Pie Day! How can they celebrate Pi Day?”. Actually, it turns out to be Pi Day! I began to wonder what they would do on a day dedicated to the Greek alphabet or the number Pi. I even wondered if they would eat lots of Pies on the day. Surprisingly, I was half right. They do do that. They even run around in circles. Literally!! For those like me, who had no idea what this day is all about, here is some info on Pie day! Oops!! Sorry! Its Pi Day! Pardon my typing error. Its cause of my partiality towards Fruit Pies than the mathematical Pi. I hated trigonometry and mensuration. Period!! I was miserable at that! Darn! I even hate being reminded about that! Well, Back to Pi Day!
Pi Day is to commemorate the mathematical constant Pi. Why March 14? Simply because, March 14 in MM/DD format is 03/14 or 3/14. 3, 1 and 4 are the most significant digits in Pi. Om March 12 2009, the United States House of Representatives supported the designation of Pi Day as March 14.
Larry Shaw, a physicist, was the creator of Pi Day in 1989 and it was celebrated at the San Francisco Exploratorium where he worked. It was celebrated with staff and public marching around one the Exploratorium’s circular spaces and eating fruit pies.
Pi represents the relationship between a circle’s diameter and its circumference. The Greek Letter Pi, was first adopted for the number as an abbreviation of the Greek word for Perimeter by William Jones in 1706. The constant is also known as Archimedes‘ Constant who was the person who provided an approximation for the number. The usage of Pi became popular after it was adopted by the mathematician Leonard Euler.
Pi is an irrational number. That is, it cannot be written as a fraction of two integers. Pi is also a transcendental number. That is, there is no polynomial with rational coefficients for which Pi is a root.
In 2015, Pi Day will be represented as 3/14/15. That is, 3.1415. Five digits of Pi. The other related celebration day is Pi Approximation Day. It is celebrated on July 22, 7/22 or 22/7, which is the approximation of Pi; 22/7. This date is also referred to as European Pi Appreciation Day. The reason is that the Europeans place the day before the month.
The value of Pi is:
Here is an excerpt from a poem by Nobel Laureate Wislawa Szymborska,
The caravan of digits that is pi
does not stop at the edge of the page,
but runs off the table and into the air,
over the wall, a leaf, a bird’s nest, the clouds, straight into the sky,
through all the bloatedness and bottomlessness.
Oh how short, all but mouse-like is the comet’s tail!
