83,431 Recited Digits of Pi

i_like_spam writes "59-year-old Akira Haraguchi of Japan recently broke the world record for the recited number of digits of Pi. Haraguchi-san recited an amazing 83,431 digits of Pi during a 13-hour overnight stretch. This almost doubles the previous record of 42,195 digits by fellow Japanese Hiroyuki Goto. Though it is not yet updated to reflect the new record, the Pi-World-Ranking-List has the rules for participation and breaks down the ranking by world, continent, and country. Links to world rankings for memorized digits of E and Sqrt(2) are also given."

    A 59-year-old Japanese psychiatric counselor set a world record of sorts Sunday by reciting "pi," or the ratio of the circumference of a circle to its diameter, to 83,431 digits.

    Good, now she can counsel herself on having more exciting things to do than learning and reciting the digits of a number anyone of us can look up.

    Understandable. Had you been a *physics* major you would have noticed that he recited pi at a *faster* rate than the previous guy and thus the metric of the frame of reference gets *dilated*, giving just a bit over the aformentioned factor of 2.
