## Unscramble the Blue Letters

And other mathematicians did the same sort of thing. A Swedish mathematician, von Koch, decided that instead of suiatnrtbcg lines, he would add them. And so he came up with this biuuafetl curve. And there's no particular reason why we have to start with this seed shape; we can use any seed shpae we like. And I'll rearrange this and I'll stick this somewhere — down there, OK — and now upon iteration, that seed shape sort of unfolds into a very different looking structure. So these all have the ptoerpry of self-similarity: the part looks like the whole. It's the same pattern at many different scales.

And other mathematicians did the same sort of thing. A Swedish mathematician, von Koch, decided that instead of **___________** lines, he would add them. And so he came up with this **_________** curve. And there's no particular reason why we have to start with this seed shape; we can use any seed **_____** we like. And I'll rearrange this and I'll stick this somewhere — down there, OK — and now upon iteration, that seed shape sort of unfolds into a very different looking structure. So these all have the **________** of self-similarity: the part looks like the whole. It's the same pattern at many different scales.

## Original Text

And other mathematicians did the same sort of thing. A Swedish mathematician, von Koch, decided that instead of subtracting lines, he would add them. And so he came up with this beautiful curve. And there's no particular reason why we have to start with this seed shape; we can use any seed shape we like. And I'll rearrange this and I'll stick this somewhere — down there, OK — and now upon iteration, that seed shape sort of unfolds into a very different looking structure. So these all have the property of self-similarity: the part looks like the whole. It's the same pattern at many different scales.
