I recently returned from an extensive visit throughout China and was struck by how solar hot water heaters seemed to be atop virtually every building, most of which seem to be made by the same manufacturer. When I asked, I was told that they’re cheap and they work. Of course, there’s no backup source; in China, cloudy, cool days preclude any hot water at all. I came away with the feeling that we will see such simple solar hot water use like this spread throughout the world.

Ted:
You are right, quadratic is what I should have used. Thanks for pointing this out.
I changed the phrasing entirely and kept it simple.

“For instance, we learn that because the relationship between diameter and surface area is exponential for a circle”
I don’t think exponential is the word you’re looking for (it implies e^x). Perhaps quadratically?
