Extractions: Recently on MathTrek: The Limits of Mathematics 2/21/98 The Counterfeit Coin 2/14/98 Nine Primes in a Row 2/7/98 February Pick a Digit, Any Digit One of the most amazing mathematical results of the last few years was the discovery of a surprisingly simple formula for computing digits of the number pi. Unlike previously known methods, this one allows you to calculate isolated digitswithout computing and keeping track of all the preceding numbers. "No one had previously even conjectured that such a digit-extraction algorithm for pi was possible," says Steven Finch of MathSoft, Inc. in Cambridge, Mass. The only catch is that the formula works for hexadecimal (base 16) or binary digits but not for decimal digits. Thus, it's possible to determine that the 40 billionth binary digit of pi is 1, followed by 00100100001110. . . . However, there's no way to convert these numbers into decimal form without knowing all the binary digits that come before the given string. In hexadecimal form, the number pi is written as 3.243F6A8885A308D313198A2E0. . . , where the letters stand in for the hexadecimal equivalent of the base-10 numbers 10 (A), 11 (B), 12 (C), 13 (D), 14 (E), and 15 (F). It's straightforward to convert a hexadecimal expression into binary form but not into decimal form.

Extractions: Ivars Peterson's MathTrek March 2, 1998 One of the most amazing mathematical results of the last few years was the discovery of a surprisingly simple formula for computing digits of the number pi. Unlike previously known methods, this one allows you to calculate isolated digits - - without computing and keeping track of all the preceding numbers. No one had previously even conjectured that such a digit-extraction algorithm for pi was possible, says Steven Finch of MathSoft, Inc., in Cambridge, Mass. The only catch is that the formula works for hexadecimal (base 16) or binary digits but not for decimal digits.

It's straightforward to convert a hexadecimal expression into binary form but not into decimal form. The novel scheme for computing individual hexadecimal digits of pi was found by David H. Bailey of the NASA Ames Research Center in Mountain View, Calif., Peter B. Borwein of Simon Fraser University in Burnaby, British Columbia, and Simon M. Plouffe, now at the University of Quebec in Montreal.

Extractions: Ivars Peterson's MathLand November 11, 1996 You happen upon the number 1.6180339887. It looks vaguely familiar, but you can't quite place it. How can you find out whether this particular number is special in some way, perhaps as the output of a specific formula or the value of a familiar mathematical function? If you have the kind of phenomenal insight and prodigious memory that mathematician Karl Friedrich Gauss (1777-1855) had at his disposal to work out such problems, you might be able to figure it out on your own. Otherwise, you could consult the Inverse Symbolic Calculator, which is somewhat like a spell checker for numbers. You can find it on the World Wide Web at http://www.cecm.sfu.ca/projects/ISC/ISCmain.html . You enter the number in the blank space provided, click on "run," and await the answer. In this case, the database search produces a page of formulas and functions that could generate 1.6180339887 (rounded off). The most intriguing possibility is the expression (1 + sqrt(5))/2, which represents the golden ratio of Greek architecture and design. The Inverse Symbolic Calculator (ISC) is an ongoing project of the Center for Experimental and Constructive Mathematics at Simon Fraser University in British Columbia. The work is largely that of Simon Plouffe, with help from a variety of collaborators, including the brothers Peter and Jonathan Borwein.
