100,000 Digits of Pi?

Published on Thursday, October 05, 2006 in , ,

Akira HaraguchiLast year, I mentioned Akira Haraguchi, who recited 83,431 digits of Pi from memory. He has just bested his own personal record, and may be the new world record holder for reciting the most memorized digits of Pi, if his claim is verified by Guinness World Records.

Akira Haraguchi has recited 100,000 digits of Pi from memory, and has submitted the video of his recitation to Guinness for verification. He started at 9 AM (Japan Time) on October 3rd, 2006. Passing his previous record of 83,431 digits at about 10:30 PM that night, he finished this amazing feat at 1:28 AM the following morning!

For those interested in memorizing Pi, you can start with the basics, and quickly learn 400 digits of Pi! 400 digits is, at this writing, enough to put you among the top 50 memorizers in the world, according to the Pi World Ranking List.

Do you want to set a record, but don't think you can beat 100,000 digits? Try going for a record in your city, state or country. For example, the North American Pi memorization and recitation record is “only” 10,980 digits.
