September 1997 News The decimal number system was introduced to Europe nearly 800 years ago and is a vast improvement on the previous system of Roman numerals (see " The life and numbers of Fibonacci " elsewhere in this issue). But good though it is, the decimal number system cannot represent all numbers exactly. Although sums like 4 divided by 33 result in values with an infinite number of digits to the right of the decimal point, they always have repeating patterns. We can use special dots placed above the digits to show this.

    Extractions: pi, in mathematics, the ratio of the circumference of a CIRCLE to its diameter; its symbol is p. The ratio is the same for all circles and is approximately 3.1416. The NUMBER p is irrational and transcendental. An early value was the Greek approximation 3 1/7; by the mid-20th cent. a computer had calculated p to 100,000 decimal places. The formula shown below allows one- if one wishes-to find the billionth digit of pi without first computing the preceding 999,999,999 digits. In other words

    Extractions: THE ASSOCIATED PRESS TOKYO 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. Kanada and a team of researchers set a new world record by calculating the value of pi to 1.24 trillion places, project team member Makoto Kudo said yesterday. The previous record, set by Kanada in 1999, was 206.158 billion places. Figuring out pi to much more than about 1,000 decimal places serves little purpose in math or engineering, but researchers say it helps push computing power to a new level and can test the accuracy of supercomputers. "It's an enormous feat of computing not only for the sheer volume, but it's an advance in the technique he's using," said David Bailey, the chief technologist at the National Energy Research Scientific Computing Center at the Lawrence Berkeley National Laboratory in California.

    Extractions: http://www.experimentalmath.info This is a plot of all roots of polynomials with coefficients 1 or -1 up to degree 18. Coloration is by sensitivity of the polynomials to slight variation around the values of the zeros. The color scale represents a normalized sensitivity to the range of values; red is insensitive to violet which is strongly sensitive. The bands, quite clearly visible in the plot, are unexplained.

Bailey of the Lawerence Berkeley National Lab in the USA; and (for vol. 2) Dr. Roland Girgensohn of the Technical University of Munich in Germany. In a review published in Math Reviews, mathematician John H. Mason writes, "Let me cut to the chase: every mathematics library requires a copy of this book (and its companion volume)" Review .
