NUMBERPHILE

[Ollervo]

Completely unnecessary, but absolutely awesome!!

[marcoinfante]

Now, that's what I call a Milestone

[ChrisZerhusen]

The most fascinating thing about this to me is how long the piece of paper had to be given how small the printing was.  I guess I didn't really have a good concept of how big 1 million is.  Maybe I have a better one now.

[WarrenBlackHacks]

This should be printed out in concrete somewhere.

A lot of people would like to find special dates somewhere in PI and take a picture of it.

I would.

[jacoblatham]

It's a 1. In case you were 1dering.

[adammullarkey]

2:25 To be fair, they did technically manage to memorise the next 0 digits of Pi...

[philipjohansson]

Is nobody else commenting on the fact that we've now seen CGP Grey on camera, yet don't know which one he is?

[nitrodavid]

This video only Confirms my assertion that Matt Parker is the closest thing we have to The Doctor.

[rainjar]

You've officially joined the Mile Pi Club!

Happy Pi Day!

[stewarthills]

What is it with numberphile and that brown paper!?

[SpaceBurgerLP]

and on a rainy day.. some guys decided to lay down a roll of brown paper

[jonathanmoore]

So CGP Grey is one of the crew ... but I see no stick figures anywhere ... mind blown

[CleanShavenPuffin]

totally not just playing I Spy CGP Grey in this video

[pep]

I can tell you *all* the digits of pi in 1 minute....
All I have to do is tell you the first number, then wait 30 seconds, then tell you the second number, and wait half that time. I tell you the third number, and wait half THAT time until I say the next number, I keep doing this until 1 minute is up, and viola! I have listed all the digits of pi!






Thats right, I watch Vsauce

[EngineeringNS]

The video is 6:28 long... half of 6.28 = pi... HALF LIFE CONFIRMED!

[zachwiseman]

The next time CGP Grey is at an event like this could you please make sure he's wearing a Waldo shirt?

[Eclpsed]

The longest sequence of digits without a two-digit sequence not appearing (before a million) happens at about 82, 000 where there is a run of 1385 digits without "88".

[AlanKey]

According to Britney Gallivan's Paper Folding Theorem, this mile long strip could be folded in half only *12* times.
 
Length of paper required for n foldings in half:
L = (pi*t)/6  (2^n + 4)(2^n - 1)
where t is paper thickness (assumed to be 0.1mm)

[tealtopaz]

You know what makes this even better? That the video is 2π (tau) minutes long!

[dianeocello]

Brady.... Hats off to you

You have done more for math than Euclid.
