11.11.11 - Numberphile

[tiggyman93]

I was born on November 11th, 1993. That was a Thursday, my 11th birthday was on a Thursday. My 18th birthday was on 11/11/11. I have enough computer parts in my room right now to make 11 different computers... 0_0

[Timei]

My book Has an isbn with 13 digits, what's upwith that?

[MrObviouz1]

I'm guessing Skyrim's release day was a big deal in England

[ReznovRulz]

Is it all of the scratches and spots collectively or is it one dot/scratch that can't exceed an area of 4 mili? Also, will a crack, no matter how thin it is, will this scratch still make the disc impossible to read?

[SuperHalfBeat]

FUS ROH DAH!!!!!!!!

[951219bb]

Immortals the movie hit theaters that day.

[NickRele]

Another cool thing is that, in every multiple of 11, the middle numbers, are the sum of the original number multiplied, such as: 121, 11x11 1+1=2, 1-2-1, ty it, always works

[OneTrickGuitarist]

@NickRele

This only works for two digit numbers. There's a more complex form for larger numbers.

Skyrim? :o

[OoVANTUMoO]

we all love 11

[XxMikotsuxX]

That's 11-11-11, or if you in America, 11-11-11!

[irealydodominate]

11.11.11 history was changed with the release of the elder scrolls v skyrim

[MrCaptSlowe]

I was born on 11/11

[Showbigest]

skyrim release

[SlartyTHEChuck]

With the cd thing, what if you have two dots instead of just one? Can the equation somehow substitute and solve for two unknowns?

[OmgAKROMA111]

He said the result just has to be a multiple of eleven. It doesn't have to be 121. 242 is still a multiple of 11.

[OmgAKROMA111]

All 13-digit ISBNs start 978-. Just saying.

Also, binary systems don't have to be 0 and 1.

[trademark3334]

I got 242. You can divide by two to get 121 though. Maybe they're running out!!!

[P0150n3d]

@trademark3334 I got that too! I don't see your point though. you should only divide by 11 and get 22. That is right.

[jaques1950]

should be 'Doctors Who', my good sir

[911codepepsi]

Book : the moon is down ,didn't gt 121

[SergeantBalthazar]

@911codepepsi It doesn't need to get 121, just a multiple of 11.

[ztolkanek09]

Skyrim Release date?

[userbabs2018]

I prefer 11 doctor who's too

[TheMccinema]

KOnY 2012

[ABC1123581321ABC]

The most interesting part of the video to me is that he made it on 11.11.11 yet uploaded it on 11.8.11 here in the US, which I believe is 8.11.11 in the UK. That sounds like an episode for Dr Who.

[asiankev321]

Skyrim release date. :D

[superdiglett100]

James Joyce's Dubliners from Dover is 242.

[SilentC0LD]

All we need to know in life is that 1+1=3 if you don't use a condom.

[flPieman]

Vsauce sent me!

[metroid1479]

I prefer 11 doctor who's too

[iiRAZZERii]

WRONG Barcelona have 12 players including the ref

[st1cband]

i got 12!!!

[BTBWProd]

wait... a computer has a drill in it?

[0beastly0]

@BTBWProd I hope you're just kidding.

[Swatty1337]

ISBN is not an error correction code, just an error spotting code ;)

Im sure you know that, but you said it wrong in the video ^^

[davorunner]

@Swatty1337 He says Error Detection Code numerous times. He just says error correction probably by accident once or twice.

[LeadSunglasses]

I picked up a bunny suicides book and the last number was "X" :D

[svh002]

Skyrim :DD

[pmccarthy001]

Casting out your elevens is another use of 11... or was, at one time, I guess... I guess they don't teach that anymore.

[espnchris]

this video was uploaded 11-08-11 wtf

[Ultranist]

SKYRIM!!!!

[chattyw87]

Wanring: placing disks with holes in disk players may damage the disk player. Because the force produced from spinning an uneven mass isnt along the axis of the axel of the disk player.

[OutrageSC]

So guess wut we're gonna talk about today?

...wut

11!

[dude15111]

1 isn't a prime number... hahaha

[DaiannaGiselle]

OMG ELEVEN DOCTOR WHO! I'm in love with you hahaha xD

[Mrstiggy200]

my total came to 205 divide by 11=18.63636363636364

[1l0r1a3c]

@Mrstiggy200 your math was wrong, try again

[RazXVIII]

but if i even touch my xbox while its playing a game, it eats the disc...

[est101010]

Oh god, that penmanship.

[poleeed]

FUS RO DAH!

[punkisnotdead41]

Why do the people on this channel always say "not" instead of zero? (American here)

[DavidPlim]

@punkisnotdead41 Actually we say Nought (Noort) over here in England. Just sounds sexier I think.

[67morri67]

Docter who!!!! :D

[gamerseye171]

So, guess what we're going to talk about today?

What?

Me: TWELVE!

[gredangeo]

The only place that has to be perfect is the barcode in the middle. Got too big of scratches on that. Disc is destroyed. no matter how clean it is.

[canecky]

FUS RO DAH!

[fatwreckdsucks]

no matter where in the video you press pause, he is making a weird face.

[OMGxxJEWS]

Hello, anyways he said he made this video on 11.11.11.

yet under the thumbs up button it says "Uploaded by numberphile on Nov 8, 2011"

Ha caught cha!!!!

[theflubbybear]

@OMGxxJEWS I'll bet he can prove himself correct.

[RAWRxBlueDino1028]

time travel. obviously.

[XxDiNoSaruSxX]

@OMGxxJEWS he says that it was MADE on 11.11.11 doesn't mean he uploaded it on that day.

[ixcaliber]

@XxDiNoSaruSxX Well he didn't make it on that day either, unless he can travel backwards in time.

[XxDiNoSaruSxX]

@ixcaliber what if he's the next doctor who?

[iassen1]

@OMGxxJEWS seems like you never heard about time travel

[KARLO1ROCKS]

@OMGxxJEWS He said the video was made 11.11.11. he never said it was going to be uploaded that day...

[OneTrickGuitarist]

@KARLO1ROCKS So he went back in time.

[cc3493]

@OMGxxJEWS he could of still made it that day, just didnt upload it then. awks

Dovahkiin, Dovahkiin, nol lok zin los vahriin!

[grarg12345]

@Willyj1230 hell yeah dude!

[Ruudofzo]

What's the exact theory behind the 13-digit ISBN codes? I noticed most of my books have 13-digit ISBN codes and if I start with multiplying the first number bij 13, the second by 12 etc and if I add those numbers together and divide it by 10 it won't give me a multiple of 10

[Minjask6572]

i think the team would be happy to know that the book i used is The History of Mathematics by David M. Burton

[TheVJackV]

my check number is X

[Zoro4rk]

yo dawg, i heard you like the number 11.

[dondude69]

Why so many dislikes I wonder?

[MisterRedstone]

[TheTrueRandomness]

*super excited voice* Guess what we'll talk about today!

Brady: What?

*are-you-serious-voice* .... eleven...

[T0astCast]

FOReST

[GOVERMENT100]

can there be multiple holes and still work?

[geminwanzo]

that is my nephew's birthday :D

[awesomegawd]

@geminwanzo and my sister

[fossil98]

My book's ISBN ends with X as it's 10th digit

[Lepug101]

can he prove that 2+2=fish?

[roadkillrabbit69]

@Lepug101 More interestingly, can he prove that it doesn't!?

[851852093114208513]

@Lepug101 - If it did, I'm sure he could.

[SNAPquizgames]

@Lepug101 fish is 4 digits which 4=2+2 lol!

[gameplace123]

wow you somehow managed to make numbers boring

[Youdontknowtherainbo]

nice

[Mokijr]

What about 12.12.12?

[Kageshen]

@Mokijr That's not binary, lol.

[sn00py414]

damn i learned more here then in school......

[soaffb1337]

@stuzicams you can but it won't be a whole number

[IrksomeBigfoot8]

11 is my new favorite number, you can do anything with it!!!

[StuziCamis]

@IrksomeBigfoot8 you can't divide it by any integer other than 1 and 11

[IMakeOrWatchVideos]

so would 121 be a checksum?

[Jans13m]

Great video! Fascinating.

[BlackManSlim562]

This girl wanted me to ask her ou ton 11.11.11.

I didnt do it

[stjonal]

doctor who!!!

[house1098]

1 is not a prime number. For the fundamental theorem of arithmetic to hold true it was neglected as a prime number.

Love your videos though

[shadeslate]

A number between naught and 10? You guys don't say ZERO?

[FallenAngelZH]

How did I get here from Jon Lajoie?

[FireFightWrestling]

[BlockisticStudios]

why was this posted on november 8

[ginger0491]

@BlockisticStudios

thats becuase the uk has a different time zone, so to us it it was uploaded on the 8, but to them it was posted on the 11

[MrThegoldenballs]

@BlockisticStudios Time travel.

[xXGrizzOutXx]

@BlockisticStudios CoD MW3 came out.

[BlockisticStudios]

@xXGrizzOutXx

You responded to the wrong person.

[xXGrizzOutXx]

@BlockisticStudios No, no I did not...

[BlockisticStudios]

@xXGrizzOutXx

Yeah well

it's got nothing to do with the release date of this video

[xXGrizzOutXx]

@BlockisticStudios Then why is the top comment about Skyrim? Does that have anything to with it?

[BlockisticStudios]

@xXGrizzOutXx

Yes, because this video is about 11-11-11, not 11-8-11, even though it was released on that date. That wasn't intended. Seriously? I'm pretty sure I meant COD's release date had no direct connection with the release date of this video, even though they coincidentally appeared the same.

[Peaches1300]

@BlockisticStudios Nov. 8th is Klaine day. :)

[MrSkinnyBill]

@BlockisticStudios Good Point, but it was probably uploaded privately on the 8th and made public on the 11th :)

[BlockisticStudios]

@MrSkinnyBill

i guess??? i don't really see the point in doing that though

[2669Randy]

so you figured out how bar-coding works... cool?

[icicicles]

Ever look at the clock and it reads 11:11 or 1:11 and wonder why?

I know why.

[MrMeddyman]

11-11-11 Skyrim came out....Nothing else happened

[mxm2400]

@MrMeddyman

Minecraft was supposed to come out then.

[MrMeddyman]

@mxm2400 That too but it was already in beta for a year before then and I wasn't too amazed

[littlemann211]

@MrMeddyman it was national heavy metal day

[Ehal256]

Binary is just a way of representing numbers, so every day is a 'binary day'.

[XthebigXcheeseX]

Lol WTF? "On eleven, eleven, eleven. Or for Americans thats eleven, eleven, eleven"......hmmmm yea us Americans are just sooooo fucking different man

[carloldelpizzo]

@XthebigXcheeseX 11 Nov 2011 vs Nov 11 2011. Its a joke. i hope your comment is one as well.

[XthebigXcheeseX]

@carloldelpizzo Yea its a joke, but he pointed out a difference that wasent different at all? lol

[MrNiCK10111]

"guess what we're gonna talk about today"

[bpassmore639]

thats my moms B DAY

[cheer56781]

My birthday was 11-11-11 and my aunt had a baby on 11-11-11 and she was born in room 11 of the hospital and my house number is 1111. I guess 11 is my lucky number(:

[ilovevideogamedude]

MY BDAY YAAAAAAAY

[mycrapychannel99]

my house address's is 1111 lucky st and my cousins b day is on 11.11.11

[EymSmiley]

only thing special about 11-11-11 was Skyrim's release.

[luigitheracoon12]

11-11-11 at 11:11 and 11 seconds

[Nuroara]

the video is a lie...it was posted 11.8.11...

[scratch1237]

11-27 my b day, add up the digits you get 11 add those digits get 2 my first lucky number because every one has two lucky numbers. Then you add the digits of only the day of the the month so i would get 9 as my second lucky number. Add my lucky numbers up you get 11

[BloodArrow97]

Have you all forgotten the true reason that makes the date 11/11/11 a great day to be remembered throughout history? It is no amount of single achievements, nor binary coding, but it is a day of great celebrating. Celebrating of what is one of the greatest released pieces of technology of all time. This is the day for... SKYRIM! The other stuff is still pretty cool, though!

[ROLF1218]

Why is the "e" the only letter not capitalized in the stands?

[Crazyforlou]

I had a surgery on 11-11-11, and now here I am doing Chakra meditaions and being introduced to DNA change..... hmmm....I wonder what it all means....?
