Pi is a mathematical constant whose value is the ratio between the circumference and the diameter of any circle in a Euclidean space, and the symbol of Pi (π) was first proposed in 1706 by the mathematician William Jones.
Pi is an irrational number that extends to infinity, but is approximately equal to 3.14 (hence celebrated on the 14th day of the third month) or 22/7. From 2009 to 2012, she was an award-winning syndicated columnist for a number of daily newspapers from NY to Texas.

This year Google made a decision to mark the 30th occurrence of this event with a nod to "the number's delicious sounding name". If you ask an engineer, he'll say "Pi?" Today's Google Doodle has been baked and built by award-winning pastry chef and creator of the Cronut - Dominique Ansel who pays homage to the well-rounded mathematical constant by representing the pi formula (circumference divided by diameter) using pie.
How Many Numbers Are in Pi?
Pi can be calculated by hand. Although it involves a fair amount of deftness and accuracy, it is possible. The website also has a record of the problems from previous years.
March 14 is celebrated as Pi Day when the date lines up in the numbers of the famous constant.
Wednesday marks the 30th anniversary of Pi Day's creation and celebration as a holiday, and it's also coincidentally physicist Albert Einstein's birthday. The challenge, which was created by the Education Office of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, is now in its fifth year.
