It is approximately 22/7 and is usually calculated to 3 digits, 3.14. With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal. Pi is an irrational number meaning it will continue infinitely without repeating. The symbol for pi, , was first used in 1737 by William Jones, but was popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737.

...and continuing updates Why "The story of pi reflects the most seminal, the most serious and sometimes the silliest aspects of mathematics. A surprising amount of the most important mathematics and a significant number of the most important mathematicians have contributed to its unfolding directly or otherwise. Pi is one of the few concepts in mathematics whose mention evokes a response of recognition and interest in those not concerned professionally with the subject. It has been a part of human culture and the educated imagination for more than twenty five hundred years. The computation of Pi is virtually the only topic from the most ancient stratum of mathematics that is still of serious interest to modern mathematical research. And to pursue this topic as it developed throughout the millennia is to follow a thread through the history of mathematics that winds through geometry, analysis and special functions, numerical analysis, algebra and number theory. It offers a subject which provides mathematicians with examples of many current mathematical techniques as well as a palpable sense of their historical development." The above passage is taken from the introduction to "Pi : A Source Book" by L. Berggren, J. Borwein and P. Borwein. It is a large collection of papers on pi and will appear with Springer-Verlag sometime in 1997. Much additional material is available in the 1986 Wiley volume

The Topic: Pi Easier - Pi sounds like pie and is equal to about 3.1416. In math, this is the ratio of the circumference of a circle to its diameter. In other words, pi is a number that equals the quotient of the circumference of a circle divided by its diameter. Many people celebrate pi by holding a Pi Day on March 14th or 3/14. Harder - The Greek letter pi represents the number by which the diameter of a circle must be multiplied to obtain the circumference. Pi is an irrational number. That is, it cannot be written as a simple fraction or as an exact decimal with a finite number of decimal places. However, you can increase the number of digits until you reach a number as near to pi as needed. Mathematicians with computers have calculated pi to millions of decimal places. Pi is used in several mathematical calculations. The circumference of a circle can be found by multiplying the diameter by pi (c = pi X d). The area of a circle is yielded by multiplying pi by the radius squared (A = pi X r-squared). Pi is also used to calculate the area of a circle, and the volume of sphere or a cone.

26. Darren Aronofsky Online: Pi Reviews, Multimedia, and more about the legendary indie film, pi! Directed by filmmaker, Darren Aronofsky. http://aronofksy.tripod.com/pi.html

News Interviews Biography Previous Films ... Home Chaos Theory Expanded. FILM: Pi (Released in 1998) STARRING : Sean Gullette, Mark Margolis, Ben Shenkman RATING: R Chaos theory, for those unfamiliar with the term, is based upon the little things that can cause big disruptions in our world. Take the butterfly effect for example; a butterfly flaps its wings somewhere in China and the wind that it stirs up may someday change weather patterns in New York. (Hey, it just might happen!) Time travel is one of the biggest mind bogglers in the our world today. Just going back could change the whole outcome of human history. Yeah, it's a lot to think about, and this film builds upon theories similar to these...more than the rest of the world may want. Darren Aronofsky is now an instant legend in indie-filmmaking for this film. It is incredibly original, smart, somewhat disturbing, and may stick in your mind like crazy glue. I have never seen a film that has so challenged my perception of reality since David Lynch's Eraserhead. (Viewers have often compared the two films for their similarities in mood and style.) Although, I was kind of thrown off by Eraserhead's metaphores that only Lynch understood, Pi had me gripped until the end. Gullete plays Max Cohen, a mathematical genius on the brink of a new discovery, and also on the edge of insanity. Everything around us is comprised of patterns, and Max is trying to find one in the largest productions of ordered chaos: the stock market. With the aid of his giant computer system, Euclid, he tries to find a pattern in stocks that are traded every second. After uploading a disk with a Hebrew alphabet, Euclid prints out a two hundred and sixteen digit number that may in fact be the very name of God (According The Torah). Hounded by a stock firm who will do anything to retrieve the code from him and his uncontrolable migraines, Max finds himself in a mess that may or may not end his life.

Some might define it as the ratio of a circle's circumference divided by its diameter. Others might think it's an irrational number that's impossible to know completely. Still others might think it's a mystical, transcendental, almighty number that will only finally be revealed when society as a whole puts on a bunch of purple felt jump suits and hitches a ride on a nearby comet.
