Dear Polygon Creators,

The difference between knowledge and a hunch is how well it’s explained. Often, we look at things and know what it is, but what we’re really doing is quickly recognizing the properties that make it what it is. Learning isn’t about knowing what a thing is. Learning is about observing, investigating, and explaining the properties that make it that thing.

So before you call something a square, stand on a little better authority and say, “It’s a square because it has 4 equidistant sides that all meet at 90 degree angles.” A square isn’t something that we draw on paper: it’s the idea of those properties. And ideas lead us to imagine things that were previously unimaginable.

Sincerely,

Mr. H
