But where they are relative to one another is always governed by this two to one ratio.

We'll probably come back to it, but a two-to-one ratio, that ends up being an octave in music.

So this note, if you count the vibrations of the string, they're twice the speed of this note.

And that's crazy because long before we were able to count the vibrations of the string that rapidly, you can just hear that that's an octave.

So that means somehow our brains do something like computing...

the relationship of the number of vibrations of one sound to another.

Mm-hmm.

So that's an octave relationship.

It's also, if you're just playing a drum beat, it's crazy, but those three moons, it's a simple, like, four-on-the-floor drum beat.

Mm-hmm.

So if you're a hi-hat going... And that's your... That's EO, the inner planet.

And then we'll put the snare drum on the third beat.

That's a four on the floor beat, but that is basically that relationship in terms of a drumbeat of what you see in those moons.

It means that ratio of like one to two to four is something that governs their movement.

It's so precise that when scientists in the 17th century were trying to solve the problem of how to keep time when you're at sea, the longitude problem, one of the main ways they were trying to do it is by...

being able to observe the moons of Jupiter because it's such a precise clock.

I mean, if you go to church every day, or sorry, every Sunday, and nobody claps, then you're not going to learn to clap.

You're not going to learn where to clap.

If you go to church every Sunday where everybody's clapping on the songs all the time and it's participatory...

then that's just going to be partly what to do.
