Updates
  • - The pi searcher hardware has been upgraded to a new, energy-efficient "wimpy node" (our term for a low-power but not too fast server). The new server uses an Intel Atom D510 processor and has 2GB of memory. Fortunately, this is about 4x faster than the old server, so Pi searches should be that much more zippy and the entire server now uses only 25W, substantially reducing the energy footprint of the Pi Searcher. - It's not Pi day, but 01/01/10 has a nice numerical ring to it anyway. Fixed a few long-standing Pi searcher bugs if you searched off the end of our 200M digits. Happy 2010, everybody! - Happy tenth birthday to the Pi Searcher, and happy pi day 2006 to everybody! This year's pi day updates: 1) New, zippy fast index-based searching; 2) The Pi searcher pages are now fully XHTML and CSS-happy, with a new look; 3) We've added a page describing

Assuming pi is normal, we have the following probabilities:
probability of occurrence for character 5 or fewer chars is 6 chars is 7 chars is 8 chars is 9 chars is 10 chars is
probability of occurrence for hex 7 or fewer digits is 8 digits is 9 digits is 10 digits is 11 digits is 12 digits is
In 1996, NERSC Chief Technologist David H. Bailey , together with Canadian mathematicians Peter Borwein and Simon Plouffe, found a new formula for pi. This formula permits one to calculate the n-th binary or hexadecimal digits of pi, without having to calculate any of the preceding n-1 digits. This formula was discovered by a computer, using Bailey's implementation of Ferguson's PSLQ algorithm. More recently (2001), Bailey and colleague Richard Crandall of Reed College have shown that the existence of this new formula has significant implications for the age-old question: Are the digits of pi random?

What is pi ( )? Who first used pi? How do you find its value? What is it for? How many digits is it?
By definition, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it. For the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it. Here's pi to many more digits: 3.14159265358979323846. The area of a circle is pi times the square of the length of the radius, or "pi r squared": A = pi*r^2 A very brief history of pi
Pi is a very old number. We know that the Egyptians and the Babylonians knew about the existence of the constant ratio pi, although they didn't know its value nearly as well as we do today. They had figured out that it was a little bigger than 3; the Babylonians had an approximation of 3 1/8 (3.125), and the Egyptians had a somewhat worse approximation of 4*(8/9)^2 (about 3.160484), which is slightly less accurate and much harder to work with. For more, see A History of Pi by Petr Beckman (Dorset Press).

There is actually an infinite amount of information hidden in pi, so it must be possible to find any information in it if you just have enough time and computing power. For example, has anyone ever tried to let a computer treat the binary digits of pi as a piece of digitized sound? Maybe the voice of God is sampled into pi, or a piece of music, or just white noise. It would be disappointing to discover that pi is nothing more than just the ultimate white noise generator!

  • Pi Videos Pi is an extremely interesting number that is important to all sorts of mathematical calculations. Anytime you find yourself working with circles, arcs, pendulums (which swing through an arc), etc. you find pi popping up. We have run into pi when looking at gears spherical helium balloons and pendulum clocks . But you also find it in many unexpected places for reasons that seem to have nothing at all to do with circles. On one level pi is simple: It is the ratio of a circle's circumference divided by its diameter. This ratio, for any circle, is always the same - 3.14 or so. You can prove this to yourself with a circle, a piece of tape and a ruler. Look around your house and find something circular: a jar lid, a CD, a plate - whatever you can find that is circular, the bigger the better. Measure its diameter (the width across the center of circle) with the ruler. Now wrap a piece of tape around around the circle and cut or mark the tape so that it is exactly as long as the outer edge (the circumference) of the circle you are measuring. Measure the piece of tape. With a calculator divide the length of the tape by the diameter you measured for the circle. The answer you will get, if you have measured accurately, is always 3.14.

    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

    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.
