"Humanity tends to think along straight lines in the things that we build and the way we often think. But rivers don't tend to follow this same linear form. In fact, rivers follow a meander pattern. Their flowing water in general tends to meander. This is true of streams of all sizes: everything from tiny rivulets on glacial ice to the Gulf Stream in the ocean. Of course, the Gulf Stream doesn't have a bed or banks, and yet it follows a meander pattern. What's interesting about this meander pattern is that it tends to have a geometry, which is a function of the width of the channel. What you see here in a tiny stream table follows a similar pattern by scale that larger rivers do."
