# Thread: Man Recites Pi to 100,000 Places

1. ## Man Recites Pi to 100,000 Places

A Japanese mental health counselor recited pi to 100,000 decimal places from memory on Wednesday, setting what he claims to be a new world record.

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, his office said Wednesday. He made the attempt at a public hall in Kisarazu, just east of Tokyo.

Pi is a physical constant defined as the ratio of a circle's circumference to its diameter.

It is usually written out to a maximum of three decimal places, as 3.141, in math textbooks. But the number, which has fascinated scientists for centuries, has no theoretical limit to the number of decimal places it can be written to. It is a constant that appears in the proofs of many equations defining the universe.

"What I am aiming at is not just memorizing figures, I am thrilled by seeking a story in pi," Haraguchi said.

2. He's a mental health counselor and this is his claim to fame?

Dood needs a new hobby.

3. Gheesh and I thought I was wasting time on CC!

That's 1001 digits including the 3, damn.

5. Come on Josh, can't you do one more?

6. Actually, I could goto 32 million, just didn't want to overwhelm anyone.

7. And with that, the Asian sterotype just increased twofold....

8. Read that this morning and my thought is he's doing the math in his head as he goes, not that hard. I can't fathom the idea of remembering that many numbers, period.

9. That guy had wayyyy too much free time.

10. any purpose here? this is why we have computers....

it's theory that counts. number crunching is...well, just that.
