20200314 Pi Day
Pi Day March 14 3.14
Pi Day celebrates the pi symbol (π) and its importance to mathematics. The symbol is a Greek letter, and it is used in mathematics to represent the ratio of the circumference of a circle to its diameter. The first digits of this ratio are 3.14159, and the number continues infinitely without pattern. It has been calculated to over one trillion digits after the decimal point. Most calculations only need the first few digits. Even the spherical volume of the whole universe can be calculated by using just 39 digits after the decimal point. The symbol "π" was first used in 1706 by William Jones. It gained in popularity after being used by Swiss mathematician Leonhard Euler in 1737. The first large and official celebration of the day took place at the San Francisco Exploratorium in 1988. It was organized by Larry Shaw, a physicist at the Exploratorium. At the inaugural event, people marched around a circular space and ate fruit pies. In 2009, the U.S. House of Representatives passed a resolution supporting Pi Day.
How to Observe
Pi Day can be celebrated in a few ways:
Eat some pie—stop at a restaurant or bakery, or make your own.
Eat some pizza—some pizzerias offer discounts on Pi Day
Memorize as many digits of π as you can. You can start by learning the first 10,000 digits. Quiz yourself or challenge your friends to see who can learn the most.
Or, you can use the fractional representation of 22/7. That can work if your equation has fractions or multiples of 22 or 7 as some of the numbers.
Here, Private Investigator Sam Shoegum looks for Pi, but I think he's going to be surprised by a different kind of Pie!
