Pi Day Google Doodle: Here's How It Was Designed

On International Pi Day, Google creates formula using apple 'Pie'; watch how they did it

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. This year the Pi-Day completes 30 years. For instance, there are astounding formulae in which smaller and smaller numbers add up to pi and one of the earliest such infinite series to be discovered says that pi equals four times the sum 1 - 1⁄3 + 1⁄5 - 1⁄7 + 1⁄9 - 1⁄11 + ⋯. 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. For those who want to try their hand at creating a pie like Ansel's, all of the recipes and directions are available on Google's doodle site, but there's no guarantee it will come out looking as attractive as his. Mike Keith wrote a book "Not A Wake" entirely in Pilish.

It is a ratio between the perimeter of the circle and diameter of the same circle. The website also has a record of the problems from previous years. It is observed on this day as 3,1, and 4 are the first three significant digits of the value of Pi. A Babylonian tablet from between 1900 B.C. and 1680 B.C. calculates pi as 3.125, and the Rhind Mathematical Papyrus of 1650 B.C., a famous Egyptian mathematical document, lists a value of 3.1605. Ansel describes the process of cooking itself as a scientific process where one has to be precise, keep in mind volume and weight in a video to celebrate the Pi day. This involves the calculation of Martian earthquakes, the helium rain on Jupiter and the rotation rate of asteroids and even the solar eclipse.
