Akira Haraguchi, 60, needed more than 16 hours to recite the number to 100,000 decimal places, breaking his personal best of 83,431 digits set in 1995
All I have to say is this guy has a lot of free time on his hands.
I just wish I had his memory! ;)
I've known pi to 12 digits since I was a kid. I was looking at my calculator (which showed only 10 digits) then realized I could see two more if I subtracted 3.1 and multiplied by 100.
The number's been stuck in my head ever since - it comes in handy about once every five years.
I also know my drivers license number by heart and that's 15 digits. That's pretty much a wasted brain cell.
100,000?!? - he must have made a song out of it...
A case of irrational politicians making a number rational.
