Japan Times: Chiba man couldn't settle for just piece of pi
Akira Haraguchi says he was never a genius in school. But at 59, the Chiba man recited pi -- the ratio of the circumference of a circle to its diameter -- from memory to 83,431 decimal places...Haraguchi began to memorize pi by "translating" the figures into Japanese words in accordance with the figures' pronunciation in the language, he said. On a daily basis, Haraguchi memorized translated words. As the chain became longer, he tried to memorize them in the way that they form sentences. As the number of sentences became large, he tried to memorize them as if they form a story. "Don't try too hard. Enjoy it," Haraguchi said. "If you do it out of a sense of obligation, you will surely fail."
