Happy Pi Day!
Today, March 14th, is Pi Day. I hope you have heard of Pi Day. If you have not, please feel embarrassed by your junior high education. Pi Day celebrates the number 3.14 because March is 3 and the day is 14. 3/14 or 3.14. Pi is actually a number that deals mostly with circles. Pi, 3.14, is the number you get if you divide a circle's circumference by it's diameter. I'm not exactly a mathematician but the previous statement is what the internet told me. Most importantly, Pi is an irrational number which means it never ever ends. While we use 3.14 as a rounded number, Pi actually continues for infinite digits. Here is what 50 digits worth of Pi looks like:
Yeah, I think I'll stick with 3.14. So in honor of Pi Day, here is some Pi Trivia:
-Albert Einstein was born on Pi Day in 1879.
-In 2008 a mysterious crop circle encoded the first 10 digits of Pi.
-The Great Pyramid at Giza seems to approximate Pi. The vertical height of the pyramid has the same relationship to the perimeter of its base as the radius of a circle has to its circumference.
-In 1995, Hiroyoki Gotu memorized 42,195 places of pi and is considered the current Pi champion.
-The first six digits of Pi (314159) appear in order at least six times among the first 10 million decimal places of Pi.
-Many mathematicians claim that it is more correct to say that a circle has an infinite number of corners than to view a circle as being cornerless.
-A Web site titled “The Pi-Search Page” finds a person’s birthday and other well known numbers in the digits of pi.
So there you have it. Happy Pi Day!
