MachineDesign.com: Do You Know What Pi Is?
Yasumasa Kanada at Tokyo University set a world s record for the number of decimalplaces to which p has been calculated, establishing it to 1.24 trillion

Extractions: by Ronald Khol, Editor No, the headline is not a question asking whether or not you know to more decimal places than 3.14159. My query concerns whether you know how is used in a mathematical sense. Of what utility is it? My reason for asking is that a team of academics led by Prof. Yasumasa Kanada at Tokyo University set a world's record for the number of decimal places to which has been calculated, establishing it to 1.24 trillion places. Now let's look at the opening paragraph of an article about the event written for the Associated Press. The article begins with: "To most people, it's a funny-looking Greek letter that has something to do with circles. To Professor Yasumasa Kanada, however, pi is an obsession." Good grief! So the Associated Press feels that most people think is just a funny-looking Greek letter having something to do with circles. I couldn't believe the general public is so uninformed about math, and I thought the comment was just another example of dumb-and-dumber reporting in the mass media. So I did an informal survey, asking several people if they knew how is used in mathematics.

Extractions: THE SIZE OF PI The most decimal places to which Pi has been calculated is 206,158,430,000. Professor Yasumasa Kanada of the University of Tokyo and Dr Daisuke Takahashi made the calculation by running two different programs in 1999. The number Pi (22/7) is one of the most important numbers in mathematics. Whenever circles are involved in any calculation, Pi is a critical number. Pi is what mathematicians call an irrational number, it has an infinite number of digits after its decimal point, which follow no repeating pattern. Because of this lack of a pattern, many people have become fascinated by calculating Pi to more and more accurate values. The latest value, by Yasumasa Kanada is 3.141 followed by 206,158,430,000 more digits! The fact that Pi is a constant has been known since prehistory. In the Bible, it is stated approximately as being equal to 3. Pi is always equal to half the circumference of a circle, divided by its radius.

Extractions: Over hundreds of years mathematicians have found dozens of presentations and armies of formulas to compute the value of Ludolph's number. Regardless of this fact any new record in p calculation demonstrates the randomness of the digit series. Frequency analysis of these results didn't point out any order in these sequences.

Extractions: 4:00 pm, Monday, November 27, 1995, 4169 Beckman Institute ABSTRACT: About five years ago I had calculated pi to 1 billion decimal places using the HITAC S-820/80 supercomputer. This year, I have calculated pi to 3.2 billion and 4.2 billion decimal places by late June and August, respectively, using the HITAC S-3800/480. The main algorithm used for the calculation was based on the AGM algorithm which was suggested by Salamin and Brent in 1976. For verification, I used a fourth order algorithm which was developed in the early 1980's by Jonathan and Peter Borwein. In order to generate more than 1 billion decimal places of pi, supercomputers, fast Fourier transforms for "big-number arithmetic" and the challenge of competition were all crucial. In my talk, I will include a discussion of how I successfully implemented the algorithms, and my future plans for a new record.
