Observing Pi Day

Donna and Drew invited us for cherry pie (and ice cream) on Pi Day

Pi Day is an annual celebration of the mathematical constant π. Pi Day is observed on March 14 (3.14) since 3, 1, and 4 are the first three significant figures of π . Pi Day, as we know it these days, was founded in 1988 by Larry Shaw, an employee of the San Francisco science museum, the Exploratorium.

Pi is actually an irrational number (a decimal with no end and no repeating pattern) that is most often approximated with the decimal 3.14  (often represented by the lower-case Greek letter π), one of the most well-known mathematical constants, is the ratio of a circle’s circumference to its diameter; so for any circle, the distance around the edge is a little more than three times the distance across.

Here's an interesting article about the math, science and pies of Pi Day:
