Do you know Pi?

Check out this Japanese man who makes recites pi to 100,000 digits, from memory. It only took him 16 hours to do so...

Re: Do you know Pi?

pi = 3.1415926...

355/113 = 3.1415929... This easily remembered fraction differs from the correct value of pi by less than 90 parts per billion; that's close enough for any engineering activity I've ever been directly involved with.

I've memorized the first 10 digits and that's all I ever plan to do.

Re: Do you know Pi?

I have to say; that's a pretty impressive feat...
...but think of the poor folks that had to sit there checking it for the world record...

And in the spirit of accuracy,
22/7 is close,
355/113 is very close,
but why not just remember the *equally* as easy formula,
4( (4arctan(1/5)) - (arctan(1/239)) ) ?

On second thought, the "355/113"'s get my vote.

but you still have to memorize 6 digits to get the fraction, and then you have to divide it out

to memorize to 90 parts per billion you only have to memorize 8 digits!

I have memorized Pi - I memorized the symbol - its the key on my calculator that looks like two TT 's run together, and thats all I need to know!

BTW, Akira Haraguchi has stepped over the line and caused an unforeseeable amount of grief for millions of men all over the world. I can hear it already

[wife] IF 60 year old Akira Haraguchi can remember Pi to 100,000 digits then why cant you remember my FOUR DIGIT BIRTHDAY! [/wife]

Re: Do you know Pi?

Yeah... I read about this in the news. My math teacher says that if we memorize like 50 or 100 he'll give us extra credit...what about 100,000? Hmm...

I had the same extra credit deal in my geometry class four years ago, where you can get extra credit if you memorize pi to 50 decimal spots. It's a shame all I can remember is 3.1415926535897932384626433832795028841 off the top of my head.

I think the box that you Pi people would think outside of has totally decomposed.

Re: Do you know Pi?

isnt there a program that lets you search for stuff like your birth day, phone number, or SSI number in PI, to see how far it you have to go to find the 1st instance of it?

now I wondering if (314) 159-2653 is someones phone number?
