Well 39 places would allow you to calculate universe-size calculations to the width of a hydrogen atom. Its about 43 to get it down to hydrogen nucleus width, and after that it becomes somewhat pointless.

Oh, and I can do 72 off the top of my head.

Oh yeah?? I bet you can't manage those calculations in your head I dare you!!
Why do you remember it to up to 72? Were you bored out of your head or something...
I remember I pressed with my ti85
0
Ans+1=1
=2
=3
....
up to =100 000+
I was really bored then...

*in theory you could

I was competing with one of my friends. He got to 120 places when I was on 100, but after some time he can only remember about 40 now, and I'm stuck with the curse of 72

I have done calculations where we needed it to about 10 or 12 (I have forgotten exactly how much) for some precision particle physics stuff, but that is as far as I have gone.

Maybe the Rainman could. Well actually Hoffmans character wasn't the rainman, well you know, the movie...

The most calculated by hand ever was around 700 decimal and the last few hundreds were wrong
Of course a few millions decimals is routine calculation on a home computer..
In physical examples, you seldom need more than a few decimals as was pointed out.
In math, its used as a sum of many series, and many other things, so its decimal writing is useless.

I've read about a guy (Source : Reader's Digest in the mid-90's) who can say 40 000 digits from the top of his head. A japanese, world-record holder.

I can say more than 40,000 digits from the top of my head... what does this have to do with pi?

My best is: 3


This thread is lame.

I think Sir Penguin should win. Great quote from a great book, masterfully presented.

That's how I memorized pi. Two summers ago, I went to a summer program at the local college and there was someone there who had memorized 30 decimal places of pi. I knew 15 places, so I challenged him to a competition: whoever could memorize more decimal places by the end of the summer would win. He got to 60, I got to 100 by the end of the summer. I was bored in the fall, so I kept going, and eventually got to 200, but I forgot some of them, so I can recite about 160 now.
