You are correct. One side effect is that your credit card number is within the digits of pi, so we can all buy new Macs and charge them to you! I just ordered mine that way. Thanks!Jesus said:

pi is one of the most commonly used "secret numbers" (lock combinations, PIN, etc.).
hehe we all think we're so smart.....
raise a virtual hand who used it at least once (i did)

Jesus, that's one hell of a profound concept!
Seriously, I found that a very interesting perspective on this subject, thanks for that. This story really does blow my mind... It really, truly does not seem humanly possible! Surely there is some limit to the human mind?
(Well, actually, I guess there is.... 83,431 to be exact!)

think of a system to convert digits to letters/symbols (any will do).
by that system, the entire and precise content of this thread is exactly replicated somewhere in pi, including the NEXT post!

Hey, you're right!
Seriously, it is true that any finite sequence, encoded into digits, will occur in pi. More precisely, you can show that the chances of such a sequence NOT occurring in pi is arbitrarily small for a suitably large number of digits, under the assumption that digits of pi can have no permanently repeating patterns and are therefore "random". And in math terms showing that the probability is arbitrarily small equates to certainty.
Two pi facts:
1. The seven digits of pi starting at digit number 10,241,771 are 1573596, which happens to be the number of this post.
2. In a paper titled "On The Rapid Computation of Various Polylogarithmic Constants" in the Volume 66 Number 218 (1997) issue of Mathematics of Computation, David Bailey, Peter Borwein, and Simon Plouffe presented an algorithm for computing digits of certain polylogarithmic constants, including pi and log 2, without having to first compute the preceding digits. Using it, the quadrillionth binary digit of pi was computed. But I don't have a copy of the article so I can't tell you if it came out to a zero or a one! I'll guess zero.

This was a surprising result at the time - the slight snag for those of us who normally use base 10 is that this algorithm only works in bases that are a power of 2, (binary, octal, hex etc). In base 10 you still have to work out all the preceding digits.
i think this is the deepest macrumors thread ever, it has turned from an old Japanese guy reciting Pi into discussing the nature of infinite numbers. next, start a thread discussing Phi and the implementation of the fibonacci sequence in carbon based life and cosmic formations. let the philosophy begin.

So what did he say after the last number...
"screw it, I forget the rest"
Seriously, could he be generating the numbers by calculating them in his head instead of memorizing them? Not that 22/7 would work but it just seems almost easier than memorizing 83,000+ digits.

83,431 digits, wow.
The only part I know of pi is 3.14, and thats only because 314 is one of the 2 area codes in St. Louis and my cell phone number's area code

All you need to do is memorize an 83,432-word series of sentences where the number of letters in each word tells you the next digit of pi. Then you don't need to remember digits, only paragraphs of text, and you'll have the new world record!

In the decimal expansion of pi, the digits from position 176,452 thru position 176,457 are as follows:

They look kinda familiar, don't they?Reminds me of a Simpson's quote:
Apu: I can recite pi to 40 000 places. The last digit is 1.
Homer: Mmm... pie.
Maybe Akira just recited the eighty three thousand four hundred and thirty first digit and scrapped the rest.

As I put it earlier "How I wish I could calculate pi" where how has 3 letters, I has 1, wish has 4 etc. giving pi to 6decimal places, more than enough for most people.
Of course you could just guess pi to 6decimal places, the odds of getting it right would be 4,782,969 to 1 which is better than trying to guess the 7lotto numbers at around 14,000,000 to 1.
It's also interesting to note that starting as early as decimal place 762, you get 6 consecutive 9s. Whoever found that the first time probably thought that pi was going to be a rational number after all, only then to find that place 768 is an 8.
