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."

    Um, I'm not a math major, but since when is 83,431 > 84,390, which is double the amount of 42,195? You don't even need a calculator to figure that one out. But as far as the accomplishment goes: That's a simply amazing feat, I applaud Haraguchi greatly, How do you memorize a number that deep, I can barely remember what I had for breakfast.

This value u is the irrationality measure of x. For u=1, x is rational, (mathworld isn't quite clear about u between 1 and 2...) for u greater than 2, x is transcendental.

If you know an 80,000 digit number sequence, all sorts of sequences are going to be immediately familiar. "That's a lot like 592307816," you say of someone's last name. Why does the last name remind you of that sequence? It's hard to say, but it does, and that helps you remember the name.

In my schooldays, too, we were forced to memorize bunch of stuff that turned out to be useless (pi was not one of them though :). Coming up with a mnemonic is kinda part of culture.

For example, 3.14 1592 6535 8979 3238 4626 each of four digit groups seems to have some kind of pattern, except the first one, no?

      Not true. Memorizing the digits of Pi involves learning a specific mnemonic system optimized for long strings of digits. A typical system involves first memorizing "pegs" for each number from 01 to 99. E.g. 12 = chicken, 45 = Darth Vader. So once you've learned the "pegs", instead of memorizing the string "1245" you imagine Darth Vader eating chicken wings. There are lots of variants; this person probably knows a peg for each number from 001 to 999, and also has some kind of "pathing" technique to remember the ordering (e.g. remember a familiar path from home to work and place the pegs alongside it).
