The Scoop on Pi:
 * By definition, pi is the ratio of the circumference of a circle to its diameter.
 * Pi is a nonrepeating, nonterminating decimal.
 * Pi com​es from the Greek language.
 * That the ratio of the circumference to the diameter of a circle is constant (namely, pi) has been recognized for as long as we have written records. A ratio of 3:1 appears in the following biblical verse:

// "And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about." //
 * Pi is used in the equation that finds the circumference of a circle, (C= pi x d or C=pi x 2r), and in the "famous five" equation connecting the five most important numbers in mathematics: 0, 1, e, pi, and i.
 * You also use pi to find the area of a circle.(A=3.14r²)
 * Pi has been calculated differently through the ages. Click on the above link to "Chronology of Computation of Pi" to see the different ways pi has been calculated.
 * In April of 2009, pi was calculated to **2,576,980,377,524** decimal places.

FYpi: > [|Pi, the movie]
 * Pi day is March 14.
 * The United States House of Representatives recognized March 14, 2009 as National Pi Day.
 * In the movie "pi," which is rated R so I haven't seen it, a mathematician goes crazy trying to find a mathematical equation to beat the stock market.
