I don't think anyone will notice.- I think my big divergent observation may not hold! Clarence Lam was the first to spot that the lead n out the front of the series can explain the increasing times without the series itself needing to diverge. I suspect there is still an argument to be made around the rate at which times go up outpacing n, but I’m not sure it’ll be super intuitive.-Let me know if you spot any other mistakes!Early morning filming and editing by Alex Genn-BashProps by Matt ParkerMusic by Howard CarterDesign by Simon Wright and Adam RobinsonEnglish subtitles by Max, Rob Macdonald, Eric Rodríguez and Matt ParkerMATT PARKER: Stand-up MathematicianWebsite: http://standupmaths.comUS book: penguinrandomhouse.com/books/610964/humble-pi-by-matt-parkerUK book: mathsgear.co.uk/collections/books/products/humble-pi-signed-paperback

Things like "=B4/B2" should have been "=B4/$B$2" so I could drag the formula down. We took that out in the interest of clarity.- Yes, at 13:20 I say "the divisor ceases to lose some of its strict meaning" which is the opposite of what I meant! the sentence needs but the one negative. Either of these would work: "the divisor loses some of its strict meaning" OR "the divisor ceases to have some of its strict meaning".- Sorry, at 16:47 column D is wrong. These are different numbers using 880 but the values over in E use the correct 930. It's just a display issue and does not change the results (despite being a bit confusing!). Spotted by a few people including Thomas Klemm and AverageJon.- People have mentioned that Theorem 2 (and the conclusion) from this 1974 paper by Balinski & Young has an Alabama-paradox-beating method. doi.org/10.1073/pnas.71.11.4602- Let me know if you spot anything else.Filming and editing by Alex Genn-BashAnimations by William Marler http://wmad.co.ukVoice work by Ben Moor and Destin Sandlin.

You can also help support and shape the videos I make! patreon.com/standupmathsCORRECTIONS- If you feel a sense of déjà vu: yes, the two sections at 16:13 and 16:45 cover the same content. I tried saying it two different ways and we accidentally left both in the edit. So, let's call that 'buy one get one free' sale on learning.- At 21:42 I say "geometric mean" instead of "arithmetic mean". And that is probably not the only time. These words have lost all meaning to me.- The Patreon credits stop early! Long story.

That’s not a joke; legit mistake. I’ve made a real uss of myself.- At 09:57 I say PAPAL averages 13.1cm "per journey" when I should have said "per letter". Consider this my confession.- At 3:40 I say "So the top 4 rows, now including the letters" but I meant “now including the digits". But what are digits if not fancy letters?

Good times. (At 29:29.) youtu.be/1wAaI_6b9JE?t=1769CORRECTIONS:- When talking about the Euler Characteristic of the torus at 16:29 I say the value of zero is "only on our friend the torus" which is technically wrong. In the moment I was just talking about the sphere and the torus but loads of other shapes have an Euler Characteristic of zero. Like the cylinder.- I'm undecided if the string method of thinking about holes at 17:04 was helpful. I could have talked about the dimension of the boundary manifold, but that felt like I was repeating the previous bit too much and wanted a different way to think about it. Not sure if this counts as a 'correction' per se, but I just needed to talk to someone about it.

Mistake first spotted by Andrew Foong but I'm going to claim it's some hidden message about the number 33.- I say k is a "positive integer" a bunch when it should be "non-negative integer" to include zero. Like at 06:30, 08:48 and 14:35 (thanks Martijn Oostrom!). The formal statement on-screen at 17:15 is the official correct version showing that n is positive but k is non-negative.- Robin Houston noticed that the on-screen text at 4:19 says Erdös instead of Erdős.
