A Really Big Piece of Pi
Akira Haraguchi has recited the first 100,000 decimal digits of pi from memory, according to today's Japan Times. Took him sixteen hours. This is impressive (or insane, depending on your point of view). I've heard of a ten-year-old who memorized the Koran, and people who have memorized the entire Bible (an astonishing feat), but those have structure. 100,000 random numbers, man. I can't even talk that long without going hoarse, and I like to talk.
Haraguchi hopes his feat will be listed in the Guinness Book of World Records. The current listing is 42,195 digits; last year Haraguchi went 83,431, but that one hasn't made the book yet.
