"Pi Day" has been recognized for many years now; however, for 2015, "Pi Day" will have a special significance on 3/14/15 with the date (and time) representing the first 10 digits of π ...
History of Pi:
Pi makes the world go round. By measuring circular objects, it has always turned out that a circle is a little more than 3 times its width around. In the Old Testament of the Bible (I Kings 7:23), a circular pool is referred to as being 30 cubits around and 10 cubits across. Pi is the ratio of a circle's circumference (distrance around) to its diameter. Pi is a constant number, meaning that, for all circles of any size, Pi will be the same. The diameter of a circle is the distance from edge to edge, measuring straight through the center. The mathematician Archimedes used polygons with many sides to approximate circles and determined that Pi was approximately 22/7. The symbol (Greek letter "π") was first used in 1706 by William Jones. The letter "p" was chosen for "perimeter" of circles, and the use of π became popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737. In recent years, Pi has been calculated to over one trillion digits past its decimal. Only 39 digits past the decimal are needed to accurately calculate the spherical volume of our entire universe, but because of Pi's infinite and patternless nature, it is a fun challenge to memorize, and to calculate by computer more and more digits.
We already know that Pi can calculate the volume of a circle, but what other uses does Pi have?
Pi can be used to calculate the volume of tanks, cross-sectional areas of crop circles, volume of liquid through a pipe, or even used as a computer program to gather operating data from different computer systems, i.e. DCS systems.
Area of a circle:
A = π r2 ("A = Pi Are Squared")
This formula is the origin of the joke "Pies aren't square; they're round!"
Circumference of a circle:
C = 2 π r
Or, how many remember the value of π (Pi)? Not 3, or 22/7 (as a fraction), or even3.14. How about to ten places?
π = 3.141592653
