Happy Pi Day to all!

Although one can certainly celebrate with an edible pie, here's information regarding this mathematical holiday courtesy of PiDay.com.

*Pi Day is celebrated on March 14th (3/14) around the world. Pi is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.*

*Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi's infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.*

*Pi is the ratio of a circle's circumference 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 circumference of a circle is the distance around.*

**History of Pi**

*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 (1 Kings 7:23), a circular pool is referred to as being 30 cubits around, and 10 cubits across. The mathematician Archimedes used polygons with many sides to approximate circles and determined that Pi was approximately 22/7. The symbol was first used in 1706 by William Jones. A '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 & patternless nature, it's a fun challenge to memorize, and to computationally calculate more and more digits.*

Happy Pi Day to all and to all a good day!
