Pi: Celebrating the Irrational
March 14, 2015 § Leave a comment
National Pi Day: Celebrating the irrational. (Or is it magical?)
Pi (π), the 16th letter of the Greek alphabet, represents the most widely known mathematical constant ~ the ratio of the circumference of a circle to its diameter, which is approximately 3.14159 (which also explains why Pi Day is celebrated on 3/14).
No matter how large or small a circle is, pi will always work out to the same number. Pi is an irrational number, in that it goes on forever ~ and as such, there is no exact value, because the number has no end.
A bit of a mind bend, really.
Some mathematicians and math fans compete to calculate pi to as many digits as possible. The Guinness World Record for reciting the most digits of pi belongs to Lu Chao of China, who has recited pi to more than 67,000 decimal places. (I’d rather play scrabble, but to each their own.)
And honestly, I’m truly glad there are people with more math-oriented brains, so mine doesn’t have to be ~ and I can focus on the irrational and magical properties of words and art.
