Pi Recited to 100,000 Digits

DiAmOnDirc writes "Akira Haraguchi, 60, needed more than 16 hours to recite the number to 100,000 decimal places, breaking his personal best of 83,431 digits set in 1995, his office said Wednesday. He made the attempt at a public hall in Kisarazu, just east of Tokyo. Haraguchi, a psychiatric counselor and business consultant in nearby Mobara city, took a break of about 5 minutes every one to two hours, going to the rest room and eating rice balls during the attempt, said Naoki Fujii, spokesman of Haraguchi's office. Fujii said all of Haraguchi's activities during the attempt, including his bathroom breaks, were videotaped for evidence that will later be sent for verification by the Guinness Book of Records."

    Technically, since Pi is infinitely long and never repeats, any finite series of digits must appear at some point.


    Sorry that's a non sequitur. There are series which are (a) infinitely long and (b) non-repetitive but which nevertheless do not contain any possible (finite) sequence of digits, just consider the series 1 0 11 0 111 0 1111 0 11111 - look no repetition Ma but the subsequence '1337' (for example) does not appear anywhere.
