    A Japanese mental health counsellor broke the record for reciting pi from memory in a marathon session from Friday to early Saturday morning.


    Newspaper pictures showed Akira Haraguchi, 59, screwing up his face with concentration as he recited pi, the ratio of the circumference of a circle to its diameter, to 83,431 decimal places.


    Starting at 9 a.m. on Friday, Haraguchi, from Chiba, near Tokyo, lost his place around noon. He quickly restarted, completing his feat of recall in the early hours of Saturday, media reports said.


    Haraguchi hopes to be listed in the Guinness Book of World Records, replacing the current record-holder, also Japanese, who recited pi to 42,195 decimal places as a student, Kyodo news agency said.

    Yep he recited pi, and you recited the article from:

    Or just copied and pasted it :rolleyes:
    well just as an opinion he recited pi to 83,431 decimal places, which is an odd number, so why didn't he just recite another digit to make an even number - 83,432 d.p! :p:

    the very last digit would be '0' in base X where 'X' is an irrational number.. but of course they don't have any last number

    I think the 'last digits' are more likely to add to make 'i'

    Hehe, I like that! The last digits don't exist, they're merely imaginary, as good as i.
