Soooo basically, "Almost all numbers contain almost all numbers..."
+Mirage Uchiha Almost all numbers contain ink, toner or absence of light.
+Mirage Uchiha -No-, it's: almost all numbers contain any one chosen digit. :P Intuitively obvious if one realizes that the longer the numbers are, the more digits they contain, and the more chance for a random huge number to contain your chosen digit.
Bah, and yes, you're obviously right - when looked at it for more than five seconds I spent writing the comment - yes, almost all numbers contain any chosen number. Because infinity. :P
This doesnt make sense, i mean not what you said but what the video says.
How can there be 3 in all the numbers based on the result being 1? If the result is 1 does it mean that the numbers which do not contain 3 is 0? Thats impossible because the sum of number which contain 3 and which do not contain 3 is supposed to be 1.
LotusEater Not in all numbers - in almost all, as in - the larger the number, the higher the probability that it contains 3, and it tends to 1.
And it's the reverse - probability of a number not containing 3 tends to 0 as the number grows.
Tomasz Wota
LOL how can the number not containing 3 tend to 0? there are always more numbers not containing 3 than there are numbers containing 3.
Thats the whole point about the answer 1. That answer 1 is totally WRONG if the sum =1.
The combination of numbers 18492833949283792749192829323000023934823 is also in almost every integer. What a wonderful thing infinity is
This April fools joke got me too
+Sergio Cordova He's not wrong because infinity
infinity is wonderful OR mathematical profs are almost worthless.
Oh boy, you made my day!
That was the first thing come to my mind ;)
It sounds surprising at the beginning, but formulated the other way around it's more obvious: "the probability of any given number to NOT contain 3 goes toward zero".
ooooh yes, I was wondering how is it possible that the same thing applies to all numbers from 0-9, but this makes sense now haha, how come I didn't see that before
Now that you've rephrased it that way the whole thing is obvious. If you have a very large sequence of numbers (representing a big natural number), it would be quite surprising if there weren't a three there. As most natural numbers are really big ones, we can conclude the initial statement.
Except it doesn't, with the same logic the probability of any given number to NOT contain a 3 would be 1-(1/10)^n which tends towards 1 when n tends towards infinity. So with this logic, each number as a probability of 1 to contain AND to not contain a 3 when n goes towards infinity. But i think the whole point is the video was posted on the 1st of april.
@@debbiescott8520 Actually your logic does not hold. The probability of a large number not containing a 3 would be (9/10)^n, as each digit has a 9/10 chance of not being a 3. What you found is the probability of a number not containing only 3s, which does tend towards 1.
While the nature of the video may have been that it's a silly sort of thing to prove, the mathematics of the proof are accurate.
this video is literally "hmmm yes this floor here is made out of floor..."

Brown paper is so much better than a chalk board because you can save all your equations and then use it to wallpaper your bedroom. A chalk board just gets wiped off by some unknown entity like Mom or cleaning staff and then you have to do it all over again.

But all of the calculations are correct, it is indeed correct. That's just infinity in it's weirdness
The proof is propably mostly useless but not false
@@paulkonig9942 yes
It's not a joke. The proof is accurate, just useless as all 10 digits share that property, along with any finite combination of them (no idea about infinite combinations).

ohhhh it was April fools vid. That makes sense even tho it was still pretty legit.
1 and 4 are everywhere as well.

Seems intuitive. As the number of digits in your given number increases toward infinity, the probability that any specific numeral is left out approaches zero.
Precisely.
Almost all numbers have more than a sextillion digits.

the amount of comments taking this seriously and not realizing it's an april fools joke.. simultaneously painful and hilarious 😭😂

well that makes a lot more sense then 😐

This video could be also relationed to the biggest unsolved pi problem: if pi is a normal number that is if there is all numbers contained in the digits of pi in any base not just systems of base 10.
This was the best troll video I've seen in a long while. Thanks for making me laugh though!
In binary, all whole numbers contain the number 1 XD
Yeah, not just "almost" all but litterally all whole numbers (except 0) :P
hmm, what about 0 itself?
0 is a natural number though.
"grabs popcorn"
you can have 0 objects, yes.
Those are called positive integers. That´s a different category.
As a 999 addicted, I noticed something quite peculiar: the sum of all the digits (or digital root) of the numbers of 3 in each part always equals 1.
- 1 is self explanatory,
- 19 = 1+9 = 10 = 1+0 = 1
- 271 = 2+7+1 = 10 = 1+0 = 1
- 3439 = 3+4+3+9 = 19 = 1+9 = 10 = 1+0 = 1

correct title: "almost all numbers contain any given digit"
infinity breaks maths. again.
Math is crazy due to fact that all numbers contain digits that are 0,1,2,3,4,5,6,7,8,9 at the same timem
Dr James Grime, the gift that keeps giving !!
Meaning the same for all other natural numbers. But then again, it would mean that 100% of numbers contain all the digits, 1-9.

Not only is 3 in most numbers but it can also help with orders of magnitude & sometimes powers of ten

At 1:15, he said "It's not point one," and I thought "Yes it is point one!". I later realized that he was using the word "not" to mean 0, lol.
+bun bacheso actually it's "nought", a British English variant of "zero".

Fun fact: Here in Brazil we say "porra nenhuma" when we want to refer to something that is equal (or even very close) to 0!
This works with strings of digits as well. Almost all numbers contain a string of a trillion consecutive threes.
I thought this sounded a bit ridiculous, but then I realised when you start getting into larger and larger numbers, each number has a lot of digits. When you start tallying up numbers with 100 digits, what's the chance there'll be _no_ 3's? Very low. So most numbers with, say, 100 digits, will contain at least one of each number between 0 and 9.
You guys are Awesome.
And what about Half-Life?
You stole my idea!
Niiiiiiiiiiko Nope.mp2 episode 2
+Bill Kerman Thumbs up.
Nope.mp4
What about Banjo Threeie?
all digits are everywhere duuh
Just like the number 23. I can see it everywhere.
This works only because numbers overlap, for example numbers with 3, and 7 under 100, 37, 73, then multiply by 10 to get anything in that set.
For anyone who doesn't get it basically this works because at every multiple of ten there is another digit in that number.
Although of course, this can be generalised for other bases. :-)
I guess you'd say: if b is our base (e.g. 10 for decimal, 16 for hexdecimal), then (b↑n - (b-1)↑n) ÷ (b↑n)) tends towards 1 no matter the value of b, so in hexadecimal, almost all numbers contain a 3 (albeit a different set of numbers to that in decimal), and almost all numbers contain any one of the hexadecimal digits.
Cool fact, IMO: in binary (base 2), *all* positive integers contain a 1, not just *almost* all, although as you might guess, the number 0 does not contain a 1. However, almost all numbers contain a significant 0, just as in decimal.
Also, the first significant figure of any non-zero integer in binary is always a 1, as there are no other options besides zero and leading zeroes are not significant figures. This is made use of in the storage of floating point (binary) numbers in computing, where the leading zero of any number is not stored, to save space for one extra significant figure (in the 'significand').
BTW, a lot of interesting facts about numbers in decimal apply just as well in other bases (although sometimes for different sets of numbers), and it's amazing how different things can look through the eyes of a different base. The Hardy-Ramanujan number, 1729, doesn't look special in any way, unless you see it written in duodecimal or dozenal (base 12), under which it is written as 1001, at which point it becomes obvious that it's equal to 12 cubed plus one.
3 is almost everywhere.

It literally means:
I can think of infinite numbers that contain a three.
I can think of infinite numbers that don't contain a three.
Therefore, there are equal amounts.
But the numbers that have a three are somehow more than the numbers that don't.
Just cannot escape '3'. It is in math and how many of one thing I see when drunk.
It's rising toward 100% because of the lenght of number, and the higher probability that any digit in that number is 3 (or any other digit). Awesome video :)
If you think about it, there are infinite number of integers while there's only Ten digits to choose from. Those digits will be used often as the integer goes up.
I just love this so much. It's funny, how stupidly right this statement is!
It makes sense, the bigger numbers get the more numerical digits they share. 123,456,789 contains all the numerical digits in one number. It would be very rare for extremely large numbers not to have every numerical digit in them, just as it would be rare to have a string of 100 digits and not have every number in it.

Yeah, I think they went with 3 to grab our attention. You see, a lot of cultures have really strong, even mystical expectations for the number 3. It's my personal suspicion that this video was more of an exercise in playing with expectations, because, yes, obviously we can do this type of calculation for any single-digit number. :-D

This is the first Numberphile video I understood from start to finish...
The numbers mentioned in this video were: 1, 19, 271, and 3,439
The sum of the digits in each number equal 1. Example: 1 + 9 = 10; 1 + 0 = 1. Another example: 2 + 7 + 1 = 10; 1 + 0 = 1. One more example: 3 + 4 + 3 + 9 = 19; 1 + 9 = 10; 1 + 0 = 1.
What a coincidence xD
BuildMeASnowmanBiatch 3439/19=181, 1+8+1=10, 1+0=1

3439*271=931969, 9+3+1+9+6+9=37, 3+7=10, 1+0=1

Took me a little while but I got it. Was confused at first but it makes perfect sense if you remember that numbers get longer as you go higher. Longer numbers, more chance for your digit. Especially towards infinity.
