Look at the video length: 3.141
+God is fake bro LOL obviously not with me
Yup
+Aggad Coincidence? I think not.
Their main video is 6.28 (6.28 = 2 pi)
The pie with pies video is 3.14
The pie with pies directors slice is 6.28
Coincidence I think not
Should've called guinness and told them you had like "Most digets of pi on one piece of paper" so that someone has to check every single digit
Michael Van Camp ya lol
It wouldn't be too much in that case since it's only 1 line per page.
They still have a second roll to redo it with.
Lol it would be funny if they made one single person check them all. They would have to work multiple days. Instead of giving multiple people sections to work.
@@the_original_Bilb_Ono Indeed it's around 288 man hours (11.57 days for one person) to verify a million digits assuming one could sustain 1 digit/sec and I can't imagine it being much higher than that if one was actually checking properly.
"flight delayed" - "why??" - "bunch of guys on the airstrip playing with a mile long paper that has pi printed on it"

This was million times more interesting than the main video.
trulez and only five times longer!
Numberphile Thanks for the behind the scenes look Brady. I for one really appreciate these extra videos.
Numberphile I like the longer videos. I understand the reasons for the shorter ones, but once in a while you should do some longer ones as well. Maybe on the Deep Sky Videos channel?
Avi Tech The topic of Numberphile doesn't have much to do with Deep Sky though.
Yes I know, but Deep Sky is an astronomy channel and has nothing to do with the "raw" math we find here, or pi. See what I mean?
18:55 "If you have a polynomial with coefficients that behave themselves, you're never gonna get pi out as an answer."
- Matt Parker's definition of a transcendental number
Gotta say, that’s a real Parker Square of a definition.
Haha, behave themselves is such a rigorous definition
_you're never gonna get pi out as an_ *_answer_*
@@blipmachine What's a parker square?
Yeah, terrible. Hopefully everyone interested will look it up in Wikipedia…
how awesom is it that the first digit is 3, the 'halfwaypoint' (no. 500'000) is 2, and the 1'000'000-th digit is 1
guess the 1,500,000th might be 0.
and 2,000,000th is -1 or what
Christianz probably 9
I just checked. The 2 millionth digit IS 9, but sadly the 1,500,000th digit isn't 0. It's 5.
Also, I'm pretty sure when counting digits of pi, you'd start with the first decimal place, which would be a 1 instead of a 3. Bummer.
"That the great thing about pi, It doesn't change while its raining" -Matt Parker 2014
"If only we had a mathematical constant to calculate it" Matt you are awesome!
pls tell us the timecode of phrase
20:37
wait....is it pi
It's tau
not this again
That was the best spent 31 minutes and 41 seconds of my life.
Also, 3141 is the first 4 digits of pi!
Gairhoth indeed!
Come on now, I'm sure "some" of your life have been more exciting than this, :) But I know what you mean, I loved this video too!
then your life wasnt that exciting to this point in my honest opinion :P
But wouldn't you round it to 3.142 🤔
When they are stretching out a mile of pi, I would gather that just using a piece of it without rounding would be fully acceptable, especially as Matt is taking chunks of pi for words. :)
when you realise you've watched a half hour video about some guys printing pi out on a big roll of paper and actually fount it all entertaining :D
Why wouldn’t it be entertaining?
??
If only youtube would give me the opportunity to "ultra-like" a video. You put enourmous effort into this project. The execution, commentary, planning, filming and background of this is just stunning. Thank you so much. All of you, the filming team, the "known faces", the printers, the unseen people in the background of the printing company, the airport responsibles and all the important people I didn't even see or mention. Wow! Respect! And thanks again!
That's what adding it to favourites is for! You can also share it with your friends and have them like it for multiple likes! c:
Streunekater ultra like equivalent is a donation I guess
Thank you! It was a really fun project in the daily chore of serious customer projects. For us that get "nerdy" about the job at times, pushing the limits of what can be done.
Alts: I am above the law
But then the normal like would become useless.
Don't miss the montage from 28:25
What was the song playing during the montage? :)
August Stapput
Taurude - Pistorm
August Stapput I don't know but you can use soundhound to find out!
***** I've tried it there, no luck unfortunately :(
***** Hmm... what do you mean? :)
Only Matt Parker could make me watch an entire half hour video on pi. Great video, and a great idea.
I couldn't believe how excited he was!
??
I know that I am 5 years late, but this is the exact reason Numberphile is the best - the passion never wavers. You are the role model who shaped my love for not only maths, but learning. Please, always stay so passionate, you change so many lives for the better. Apologies for being so emotional, but that montage truly took me down a memory lane, and I'm so grateful for the support I had from Numberphile. :) Thank you!
28:52 CPG Grey revealed.
Wait really?
Now pi on brown paper is not only the logo of this CZcams channel but also one of your greatest achievements, Brady! Congratulations and thanks for this great subscriber special! :)
Zardo Schneckmag ha - thanks
*****
The ambiguity was - of course - on purpose! :)
Numberphile I would have been more impressed if you got a mile-long _pie_, but congrats! :P
While you were still in Denmark, you should have also made them do gamma, e, phi, and 1/3 to a million digits.
@@numberphile I found a better fraction for pie then 22/7 it is 195/25
The music in the ending montage really made that sheet of paper look oddly majestic.
cdplayer2397 thanks for watching the end - it's my favourite bit!
Numberphile
What is the ending song?
I love it !
Numberphile
How much did the Mile of Pi weigh?
Numberphile also did a pi song, generated from pi digits, I wonder if I can still find it...
I wonder if anyone realised. The length of this video is 31.41 (10 x pi) and the length of the actual mile of pi video is 6.28 (2 x pi)
***** I saw it was just pi up to 3 decimal digits. (3.141)
Just adding to this, 6.28 has a name :D Tau
mind blown
:D
And the montage starts in 28:26, (9pi)
11:18 "We needed to keep the video short," he says on the over-30 minute-long followup video.
And yet my printer cannot print black digits without magenta ink...
Mine can. It's actually an HP one, too.
@@Karreth r/wooosh
@@nahyanislam6742 r/ihavereddit
Cool. Now print out Graham's Number.
Okay, that may be tough. How about printing out how many observable universes you'd need to convert every atom of into ink in order to print out Graham's Number?
That number would still be too massive to print even if every digit of that could be expressed in each Planck volume in a googolplex observable universes!
Robbie Dart No problem. Just do that in a dozenal system. (sorry i couldn't resist)
Considering one (ours) observable universe is infinite, only need one.
rdizzy1 The observable universe isn't infinite, it's 93 billion lightyears in diameter.
It's only that large right this second though. It continues to grow without a proven end in sight,aka infinite.
12:37 "Here at Numberphile, we're answering all the questions that no one has every asked"
When Numberphile reaches two million subscribers, they should do two miles of Tau
+MrAlen61 it is impossible for any channel to get 1 billion subscribers now matter how popular they are.
+Audible Magician Because how can Numberphile have 1 billion subs when the Earth only has 7 people?
Well if 1 in 7 people subbed that couldn't be possible. Not everyone has internet access.Not everyone has a CZcams channel. And not everyone is interested in mathematics
reread my comment. the meems
I'm just reading these comments thinking, how is everyone so serious about this? Its so trivilal
None of those dudes looks like I had imagined CGP Grey.
I'm not going to guess. He will just remain the faceless man he is for me. :)
CGP Grey? what does he have to do with Numberphile.
master3243 He was in the credits...
master3243 the credits of the shorter video says he's part of the runway team.
master3243 CGP Grey does a podcast with Brady, so he's not directly associated with Numberphile, but he's most definitely associated with Brady Haran.
(just in case you didn't know...)
He will be out at rocket city for Random acts of Intelligence :D
I'm usually not one to be critical of people, but I don't find it possible that ANYONE, much less 51 people (as of now) could dislike this video. Absolutely amazing work. I truly wish I could have been there!
***** ha - thanks
I, on the other hand, am surprised it hasn't recieved more righteous hate. It's clearly just another shameful piece of punditry for that false idol pi, where as our true mathematical messiah Tau is nowhere to be found! #tauday #halfwaythere #piisalie

Meggy McKechnie You win ALL the things for that one!! HAHAH
2 minutes for this video are enough
This entire video plays like a professional documentary.
A Pile.
I just scrolled for this.
wait.. waiiiit CGP Grey was on the runway?! Wish we coulda heard from him too!
"Numberphile - Answering all the questions that no-one ever asked." - Matt Parker, 2014
Watching this at 3:14am. Got to love not being able to sleep.
"it's a 1 in case you're wondering" 😂😂😂😂
Now when you get 2,000,000 subscribers, you're gonna have to print out 2,000,000 digits of Tau! :D
Keiji Ikari let's cross that bridge if we come to it!
Numberphile
*When* you come to it! ;)
NOT TAU
Keiji Ikari No, e....
over 1.9 Mio subscribers you are already close
awesome project! Thanks for doing this! love the videos. I was a math major back in the day... but don't do anything with math in my career. love watching stuff like this.
Not sure why but this is one of my all time favorite numberphile videos. There's just something so plainly poetic about it. A mile of Pi in the sky?
This was so beautiful! As some others say here, it shows the power of a million :)
Congratulations on the million subscribers.
Runway Crew: CGP Grey. So Grey was there for this too. Neat.
My 3-year old, whose favorite video of yours is the one about choosing a toilet, asked if your rolls of white and brown paper were toilet paper or paper towels. Congratulations on a million subscribers! This engineer-turned-mom gets her number fix here.
Now I want a T-shirt that says "Hey look! three 7's" and shows that part of pi that has three sevens.
So true.
So true
Luckily, there's multiple, even a place with 4 and 80008 shortly after!
There's a beauty to the brown paper rolls arriving wrapped in brown paper.
Congratulations! I've been watching your videos for years, and I've always been impressed with the your ability to explain difficult subjects, and make them entertaining as well.
BMBirdsong thank you
I watched this while I was eating pie.
Jonathan Nelson what kind?
Lemon merengue. My second favorite after key lime.
Jonathan Nelson I watched it with my dog Pi
Jonathan Nelson, Reverse the text 3.14 = P1.E
Now I want to make pie and watch this again
Stunning! Amazing! Beautiful! This was not just epic, was historic! And congratulations for the millions subscribers, you guys deserve it. Greetings from Brazil.
Oh wow! That musical bit at the end nearly made me tear up.
Awesome job everyone! That looked like quite the endeavor, but it was so cool!
Tau forever!!
Since Tau is 2 times Pi you should print a million digits of tau when you reach 2 million subscribers! -> (a Mile of Tau)
2 miles, or at least 2 kilometers!
A mile of e!
gsurfer04
2.7 miles of e!
Firstly Congratulations on reaching 1 Million, secondly what a great idea (I had only seen this on a computer screen before and almost blew Microsoft Office trying to copy and paste it)
One of the most amazing videos of Numberphile. Thank you for the experience.
Classic Numberphile... Thanks so much - and wonderful music at the end!
Awesome video! This video should have been one or two seconds longer for making it 31:42.
I subscribed to the channel yesterday - and today such a video: "What a nonsense!" was my first guess - but actually I was very impressed in the end and watched every second of the video. Rly nice work! :)
PunktKommaNull that's great to hear
I had the same reaction, and I would guess many others did not watch the video, because of their initial reaction. Clearly, the project took much effort and problem-solving skills and left a sense of real accomplishment. With similar printing, how many digits would need to be printed to completely wrap the entire Earth in paper? How many digits to print paper from Leicestershire to the Sun? :-)
***** at 1:35 conversions between number of digits and lenghtscale are shown. 1km of printing displays 1 million/1,69=591,716 digits. So 40,000 km displays about 24 billions digits, and 150 millions km displays around 90,000 billions digits. Now your turn : What will be the radius of the roller of paper in both cases? Better : Assuming thickness t and length L of paper, and starting radius Rs, what is the expression for the radius of rolled paper R = R(L, t, Rs)?
*****
And as a even more exciting bonus, what is the error in that expression, if we truncate PI after the number of digits that is printed on the paper of length L, viz. e=e(L)=R(real pi)-R(truncated pi), and what need to be the length of paper (in billion light years) so that the error is 1 cm? And if each digit were a)1 planck length wide b) 0.1nm, what length of paper is needed to "print" the first 1 BILLION digits of pi?
I can't wait until we pass Pi million subscribers.
I love ALL Numberphile videos, but this is actually my favorite!
Really good job ;)
It was interesting to hear all of the Pi trivia. I was impressed that it took so little ink to print all those digits.
Very interesting video. and congratulations on 1 Million subscribers!
This is the greatest 1 million subscriber special ever
This channel is one of the most interesting channel on the internet. I can't believe how much I enjoy your show! Not only Numberphile, but Computerphile and SixtySymbols ( I think I'm missing one ). Thanks for all your work Brady, and also the speakers.
"Luckily I brought some bags of sand"
Mile of tau (2pi) for 2 million?
Thank you to everyone involved in this. It was riveting.
28:25 If you watch starting at this part it looks like the kind of video you'd play if they all died.
Am i the only on who wish they'd made the video 1 second longer?
Patrick Hansen minute*
emile_b_owner why minute? then it'd be 3240
If it was 1 second longer, it'd be 3141 ;)
no it wouldnt ;3
I still don't get how 31+1=/= 32...
Patrick Hansen It was, youtube cuts 1 second which makes it look like it wasn't... but the video should be 3.141
Brady you magnificent beast! Thank you so much for uploading this. I wanna say it made my day. Easily it did that. My week? Probably so. Probably the best CZcams I've had all month. I was glued to the screen. Sure, sure the 'main' video was also good. But, for me, that little viddy was the trailer and this is the feature. You gotta love Matt Parker, he's a witty chap. And Brady, just astounding that you put all this together. It's so gutsy and so huge. You showed us something truly awesome. I've been a big big fan since ive found Numberphile a year or so ago, and an even bigger one now. Thanks again, cheers.
Watching this nice and recordholding film of pi, makes me think that you and your whole production crew deserved a piece of pie for your 1 millionth video. Gratz
When you see a lot of channels with a million subs, or a ton of videos with millions of views you tend to forget how truly amazing that number is. Good video.
I would have expected CGP Grey to shred the paper.
From now on, the airline industry will no longer use yards/meters for MRL (Minimum Runway Length) stats. Instead we'll see, "A 747 at wax weight, 25% fuel with flaps at 40 has an MRL of 880,000 dop (digits of pi, natch!)
You've outdone yourself with these videos Brady, both the main video & the making of were treats to watch! and the work you put in to get this all together is awesome. Thanks for the awesome videos and well done on 1 million subs! =D
Great stuff Brady. Thanks for making such amazing content.
Oooh, the Top Gear Top Track!
*Test Track. but yeah.:D
Indeed!
:O
gambon is there?
No, this is Bruntingthorpe, Leicestershire (7:48), the Top Gear Test Track is at Dunsfold, Surrey.
CGP grey is one of the runway Crew!
Thanks for making this
12:38 so... here on numberphile we‘re answering all the questions, that noone‘s ever asked😂👌🏻👏🏼
I start to think that "CGP Grey" was just added to the credits to fuck with everyone lol
One more thing for Brady mausoleum... a roll o paper with one million digits of pi. I wanna hear what Grey as to say about it...
i mean he was in it so i think he didnt mind much
The montage was just beautiful.
I have to say, this is the best video I have seen!!! Good job!
I wander if CGP gray was fillmed during the day and then cut out
The thought occurs to me, if nobody has bought this after all these years, you could setup a second spool to attach the other end to and have it as a rotating reference.
This is just so delightful
13:25 - "...you can turn words into letters." You don't need numbers for that!
Great job tho, it's surprisingly satisfying watching this video for the 10th time now
there are things humans are probably never gonna know for certain, one being the reason behind the sequence of Pi another being why there were such unhappy/troubled people to downvote this video
They probably also downvote puppy and kitten videos.
Now print grahan's number
they dont know all digits
robin van Sint Annaland just joking...
+robin van Sint Annaland They don't know all digits of Pi either.
there wouldn't be enough atom in the world
Ya know, this is a great video. I'm glad I came back to see it again after a few years. It's aged very well. Your presentation style in it is fantastic, and I really enjoyed the whole experience.
I think this was the first video I watched from Numberphile, and the first video I watched with Matt Parker.... fun times!
One question. Which one is cgpgrey ? Is it the drone ? I see no other robot...
where's cgp grey in the vid?
If someone were to tell me that I'm "One in a million" I would say "Yeah I know, and you need to see Brady's video about a mile of PI, because I'm represented there somewhere and one of the million"
This is a brilliant video. The concept and execution was magnificent! Happy One Million Brady! Here's to another to come!,
This is so beautiful that it has brought me to tears.
Matt: Pi is a normal number. Me: ummmm you sure mate?
A Wild Turtle it's not normal, it's moisture invariant.
On the thing with words in Pi... Should have used base 26
I'd have thought those two guys hammering the paper into that contraption was somebody from Numberphile's dad. That is such a dad little touch.
Excellent work! This was highly enjoyable.
CGP Gray was on the unrolling team!
Do we have footage of him?
Which one is cgp grey Numberphile ?
I'm just noticing that numberphile is getting beautifully close to 3.14 million subscribers...
So good. Love watching every few years 🎂
Where can I do a offer for the roll?
lynxloco I might have some news via my mail list at at later date: eepurl.com/YdjL9
Numberphile I can do $4. its a bit more than pi
Krisna Siv hahaha
Numberphile You should sell it for 3,1415 something(Million, thousand, hundred)
Kinda disappointed that this wasn't one second longer in order to be 3141 (like 3.14159) but your original 6.28 minute video made up for it. Great video though!
Jonathan Lockwood Topping it is 31.41 on my index - CZcams does funny things with timings
The best video ever I watched...!!!! Congratulations Numberphile for such a Superb World Record..!! And an awesome video too..!! Thank you so much.!
awesome video Brady. better than the actual video, itself! lol. keep em coming! Matt had me laughing the entire time!
