This is maybe a good first thing to read if you've never heard of the Fourier Transform before, but it makes it sound a great deal more arbitrary and random than it actually is. It might set your understanding back by giving you the illusion that you understand things you don't actually understand, and that would be a shame, because some of those things are more beautiful than a sunrise or a hummingbird.

It would be very sad to lose those treasures by passing them by because you thought you already had them. As the song says:

> When you're young, you're always looking

> On the far side of the hill;

> You might miss the fairest flower

> Standing by your side very still.

And the flowers of Fourier analysis are as fair as the fairest flowers in this universe, or any universe.
