The Doodle, pictured above, spells out "Google" using pie ingredients, but also signifies the formula used for arriving at the number pi: circumference (pie crust) divided by diameter (pie dough) equals (apple cores) pi (pie). Shaw died previous year, but Pi Day is still celebrated by lovers of mathematics around the world. As for the actual first calculation of 3.14, that's largely attributed to Archimedes, the Greek mathematician and astronomer who lived in the third century B.C.
Memorizing Pi has been something that has fascinated people and there have been straight records for the same with the record for the most digits of pi being memorized by Rajveer Meena of Vellore, India, who recited 70,000 decimal places of pi on March 21, 2015, according to The Guinness Book Of World Records.
Google asked Cronut inventor Dominique Ansell to create the doodle for Pi Day which was first recognised by physicist Larry Shaw. 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).
As we celebrate again in 2018, here are some Pi Day facts you should know.
In geometry, "Pi" plays an important constant in finding out the area of a circle. It's an annual celebration of the mathematical constant, π. The Greek letter π (pi) represents the ratio between a circle's circumference and its diameter, which is the same for every circle. In layman's terms, 3.14 is only the beginning and the number goes on for infinity. The Pilish dialect was invented, in which the numbers of letters in successive words matched the digits of pi. Currently, Pi has more than 13 trillion known decimals.
