Right?

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 Trent?

And the whole, whole world is listening.

Yeah, OK.

We all know the song.

Lots of different artists have played it.

The original artist was Leonard Cohen.

He was the one to write the lyrics.

Few people know, he actually went through many, many different iterations of what the song would be.

And ultimately, it ended up as this biblical devastation of love.

But one of the earlier versions was about this particular pattern in math.

It's true. 100% true.

Leonard Cohen was a low-key math buff.

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 the right way, if he didn't make it about love and religion and all of those great things.

So I could welcome to the stage yet again, to accompany on keynote, Matt Parker, this wonderful.

And I know I'm no Leonard Cohen, but just imagine if you're watching track and when they get to that pivotal moment when you know that love is going to hold, you would actually hear the proper original. ["LOVE IS LIKE A CIRCLE"] Well, I heard there was a sequence of chords that splits the circle to one, two, then four, and points seem to come in powers of two, yeah.

It goes on like this, with a fourth and a fifth, but something's up when you add a sixth.

It falls to 31.

Patterns fool you.

I'll make you believe.

I'll make you believe.

I'll make you believe.

I'll make you believe.

Yeah.

When your faith is strong, you still need proof.

Trust can lead to a tooth.

Each integral, up on the left, is pi over two, yeah.

I think that's true for the next, which is fair.

But like a girl, we've shown that it's off by a hair.

It's a sudden slip, but it's true, yeah.

Patterns fool you.

Patterns fool you.

I'll make you believe.

I'll make you believe.

I'll make you believe.

Yeah.

Now, take a prime and write it into a score, just like you had before.

Each prime gives a new prime with this rule, yeah.

Or does it, though, eventually find new primes are not so simply designed?

Patterns hold, then they're broken.

How they fool you.

How they fool you.

How they fool you.

How they fool you.

How they fool you.

That's it.

I'm just guitaring.

Thank you very much, everybody.
