Pi Day 2018

On the other, food lovers see the day as an excuse to bake pies, which is both ingenious and delicious-and lucrative for food brands like Genius Kitchen (see our recipe for Surprise Rainbow Pi Day Cake).

March 14, 2018, is Pi Day - that's pi, not pie - and on Wednesday, Google marks the 30th anniversary of the math-inspired holiday with a special Doodle.

Today is March 14th, otherwise know as National Pi Day!

Commemorating the day, Google has posted a doodle, which includes the more edible "Pie", baked by award-winning pastry chef, Dominique Ansel.

Google states that this year is the 30th year of celebrating Pi day, as it was first recognised by physicist Larry Shaw in 1988. If you were curious, the National Pi Day official website has expanded it to a million places.

The Massachusetts Institute of Technology (MIT) and the Princeton Universities have devised their own unique ways to celebtate the day.

Pi is a mathematical constant, meaning it isn't changed by the size of the numbers it's used to equate, and it is irrational, meaning it has an infinite number of digits that never repeat.

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.

The earliest proven use of a good approximation of the length of a circumference relative to the radius is 3+1/7 and it has been used at the construction of pyramids in Ancient Egypt.

Who has calculated the most digits of Pi?

Pi is a fundamental element of many mathematical fields, but most significantly Geometry.

Pi is also a source of inspiration for competitions, where participants have to recite as many decimals of the number as possible.
