[00:00] It's two, then four, then eight, then it's sixteen. It's very nice. And before I go on with this particular pattern, there's a fun story about it. A little known fact. Do you guys know the song Hallelujah, the one popular from Shrek? [00:16] Yeah, okay. We all know the song. Lots of different artists have played it. The original artist was Leonard Cohen. He was the one who wrote the lyrics. Few people know, he actually went through many, many different iterations of what the song would be. [00:28] and ultimately ended up as this kind of biblical devastation of love. But one of the earlier versions was about this particular pattern in math. 100% true. Leonard Cohen was a low-key math buff. [00:43] And I thought it might be fun, just because I don't want the original version to get lost in the annals of history, to share with you guys what this would have sounded like. If history had turned out my way, if you didn't make it about love and religion and all of those great things. [01:01] So welcome to the stage yet again to accompany on keynote Matt Parker. Wonderful. And I know I'm no Leonard Cohen, but just imagine if you're watching Shrek and when they get to that pivotal moment [01:17] when you don't think love is going to hold, you've actually heard the proper original. Well I heard there was a sequence of chords [01:31] Splits the circle to one, two, then four And points seem to cut in powers of two Yeah, it was on like this With a fourth and a fifth [01:44] But something's up when you add a sixth And it falls to thirty-one I don't need foolin' I break forward I break forward I break forward Hallelujah Hallelujah Hallelujah Hallelujah Hallelujah [02:16] When your faith is strong you still need proof I guess I can lead to a goof, be general, but on the left is pi over two, yeah. [02:29] I think that's true for the next, which is fair, but like a girl who you've shown that it's half my hair. It's a subtle slip, but it's true that I'll pattern for you. [02:41] I'll pattern for you. I'll pattern for you. How they fool you, how they fool you [03:01] Now take a prime and write it in face four Just like you have before And the prime gives a new prime with this rule, yeah Or does it though, you'll eventually find new friends or not? [03:18] So simply design patterns, hold them, they're broken How they fool you, how they fool you [03:30] How they fool you, how they fool you How they fought and won And they fought and won [03:44] And they fought and won
