Is there a sequence of digits not in \pi?

Don't be one of those retards stating fi is in pi and pi is in fi.

No (what even is that?), I mean take an arbitrary length sequence of random numbers, say "4430791". The question is: is any such sequence in the decimal expansion of pi? If true, then pi is like the Library of Babel for numbers.

It has not been proved that the "randomness" of [math]\pi[/math] digits remains true "forever" (it could become periodic at some point, for example)
It is likely that it really is uniformly random, tho. And then, it could contain every sequence of numbers you can think of. Provided you know an infinite number of its digits, which seems absurd anyway.

I think it's an open problem. If it were true it wouldn't make pi that special though, since there would be infinitely many other irrational numbers with the same property.

Pi is a universe number so yeah...
Even better it's a normal number so we know that the distribution is some kind of randomness.

>Even better it's a normal number so we know that the distribution is some kind of randomness.
>it is a normal number
We do not know that, faggot.
It might it seem like it is normal, but we do not really know.
Stop spewing shit.

Memorized from middle school. Not once has it been useful.

For a finite string of real numbers its "likely" but I don't know if its verifiable. You would have to know all of pi before you could say what it does or does not contain, right? Theres no handy index like library of Babel as far as I know.
So yes, you could theoretically comb through pi and find everyone who was ever born's birthday and death day, but so what, how do you communicate that information? "Dude calculate pi to the ultra-mega pentagoogolplex digit and it says 80085!"
No way to sort the wheat from the chaff so to speak.
In Sagan's novel "Contact" the Ayy's tell Ellie that the didn't build the wormhole network, or the contact protocol, they and other races found it much like earth had, and eventually inherited the operation and maintenace of them. It's revealed that the advanced races of the galaxy are trying to "grow more universe." they also tell her that there are other signals and messages burried in the fabric of the universe. And that if you take certain transcendental numbers in different bases and follow them out to the nth digit there are ciphers and criptic messages that even the advanced ayy's can figure out completely.
In order to keep her happy and quiet after the mission "fails" is telescope time, and a bank of super computers sifting through transcendental numbers in various bases. The book ends with one of the computer's alarms going off.

It is suspected but not known that pi is normal en.wikipedia.org/wiki/Normal_number

I hate how people on here still do not know what this is called.

This is called a "normal" number. It's not yet known if pi is normal. Tests have shown that square roots of 2,3,5...8,10...15 *may* be normal.

Underrated post

3,141592 is all I know but never had I ever have to use it
My calculator knows better

I know up to 20 digits but it's completely useless. If I'm doing math on paper I'll just use pi symbol or 3.1416 if in need a decimal approximation. If I've got access to the calculator then there's absolutely zero need to memorize any digits of pi.

Memorized some 300 or so digits when I was ~12, have not used them to this day.

3.1415926535897 because that's about where my old TI-86 stopped and also I'm a bit of a dick but not that much.

I wanna say there's like 2558 or a 355 or somesuch just a bit further in but naturally I couldn't be fucked.

winner

Bout tree fiddeen

The sequence of digits is periodic at some point iff the number is rational, so pi's sequence is not periodic

I guess we have a winner

i just use 3.1416

>2.718281828
this is as far as i know

That one is actually kind of interesting and worth knowing just that far, due to the repeating 1828.

I used to know Φ that far as well, let me see. 1.618...033...75-something? hm.

Pi = sqrt(g)

easy.

one two skip a few 99 a hundred

I downloaded 100 million digits of π to search for my telephone number, and it isn't there.

Check my phone numbered pie digits!

Consider the first 144 decimal digits of π (which does not count the leading integer part of 3):

3.

14159 26535 89793 23846 26433 83279 50288 41971 69399 37510
58209 74944 59230 78164 06286 20899 86280 34825 34211 70679
82148 08651 32823 06647 09384 46095 50582 23172 5359

Careful review of this data and a tedious addition will show that these first-gross digits, a mildly amusing benchmark, sum precisely to 666, the so-called number of the beast (if one accepts the historical number and not the recently-discovered alternate 616 of philology). Moreover, suppose that you have access to a good piece of software which can usefully calculate and manipulate the digits of π. Then it becomes possible to construct an algorithm, which in turn can be expressed as a properly mathematical formula, and feed this formula to the software to confirm the above.

What we want to do is to isolate the decimal digits of pi up through such-and-such a point, and sum them. Describing a procedure:
The first digit can be isolated as follows: take π, multiply by 10, subtract 30 (the original integer part) and take the floor. This is 1. Store 1. Partial sum: 1.
The second digit can be isolated as follows: take π, multiply by 100, subtract 310, and take the floor. This is 4. Store 4. Partial sum: 5.
Once more, for flavor: take π, multiply by 1000, subtract 3140, and take the floor. This is (a different) 1. Store 1. Partial sum: 6.
Whither the 30, the 310, the 3140? These are, respectively: 10 times the floor of π, 10 times the floor of 10π, and 10 times the floor of 100π.
At this juncture it is now possible to express the formula, or finite series, which is to be fed to the software:

[eqn]\sum\limits_{k=1}^{144} \bigg\lfloor 10^k \pi - 10 \lfloor 10^{k-1} \pi \rfloor \bigg\rfloor = \; \; ? [/eqn]

Sure enough, this can be fed into Wolframalpha, and is quite tractable to that instrument. The expected result is returned.

22/7

A corny reference to the film, π: there, the True Name of God is described by Jews as being a 216-digit number (in base ten, presumably); 216, of course, has the factorization 6x6x6. (The actual number is reported inconsistently at certain spots in the flick).

Actually performing the tedium by hand: take 66, and subtract 22 (the sum of those last four digits), to get 644. It must be shown that the 28 remaining regular blocks-of-five sum to 644. Re-arrangement as partial sums will always yield in each case something less than 46, which makes for a very regular grid, corresponding to the above:

20 21 36 23 18 29 23 22 36 16
24 28 19 26 22 28 24 22 11 29
23 20 18 23 24 24 20 25

Surveying this crap shows that exactly 21 terms have a leading digit of two, while among the remaining 7 terms, there are 2 leading digits of 3, and 5 leading digits of 1. 644 - (420+60+50) = 644 - 530 = 114. What remains to be shown is that the 28 trailing digits sum to 114 (zeroes are thrown out):

1 6 3 8 9 3 2 6 6
4 8 9 6 2 8 4 2 1 9
3 8 3 4 4 5

Surveying this crap one last time, a simple and fast thing seems to be to break the graphic now displayed into three blocks: 35, 49 and 30. Whoop-dee-doo, it's 114, chartered accountancy is the life for me.
