Google asked Cronut inventor Dominique Ansell to create the doodle for Pi Day. He pays homage to the mathematical constant by representing the pi formula (circumference divided by diameter) using an actual pie. Incidentally, in 2009, the United States House of Representatives had voted in favour of designating today as Pi day.
Today, March 14, is no typical Wednesday - it's Pi Day - and Google is celebrating the occasion with a special Doodle and pie recipe, courtesy of one of the world's most renowned pastry chefs.
"As an irrational and transcendental number, it will continue infinitely without repetition or pattern".
Pi, which represents the ratio of a circle's circumference to its diameter, is an important part of the foundation of mathematics. 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. If you ask an engineer, he'll say "Pi?" Mike Keith wrote a book "Not A Wake" entirely in Pilish. 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.
Pi does not belong in the category of normal numbers, at least it is believed so by Mathematicians. Observers often celebrate the day with a slice of their favorite pie.
March 14 is celebrated as Pi Day when the date lines up in the numbers of the famous constant. 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. The topics this year include calculations for Martian earthquakes, helium rain on Jupiter, and the rotation rate of the first interstellar visitor ever discovered, asteroid 'Oumuamua.
