What would you say if someone asked you what was pi? Would you respond: “A tasty treat,” as most would? Well, to most mathematicians pi is an amazing treat.

Pi is actually the circumference of any circle divided by the diameter. The circle can be as large as planet Earth itself but it will always be simplified to 22/7; a mathematical constant! If pi is converted to decimal form, one will find that the numbers after the decimal point never end and never repeat themselves in the same fashion if grouped by four.

The Latin name of the Greek letter π is pi. The earliest known textually evidenced approximations of pi date from around 1900 BC. They are found in the Egyptian Rhind Papyrus 256/81 ≈ 3.160 and on Babylonian tablets 25/8 = 3.125, both within 1 percent of the true value. Until the second millennium AD, estimations of π were accurate to less than 10 decimal places. Pi is perhaps the most common ground between mathematicians and non-mathematicians.

Many schools around the world observe Pi Day (March 14, from 3.14). Several colleges cheer at the Georgia Institute of Technology and the Massachusetts Institute of Technology include "3.14159!" On November 7, 2005, musician Kate Bush released the album Aerial. The album contains the song "Pi" whose lyrics consist principally of Bush singing the digits of π to music, beginning with "3.14" So as most might agree, it is seen that pi is an amazing number. So here’s a challenge; I know pi to a thousand places, do you?
