"Transcendental Moment: Computers savor a sliver of pi," by Peter G. Brown. The Sciences, January/February 1998, page 10.
Calculating pi out to enormous numbers of digits is a sport pursued by number crunchers the world over. "But what if," the author asks, "for some nefarious or merely impenetrable reason, you just have a yen to know, say, the one-billionth digit of pi?" This brief piece describes recent efforts to address this problem.
