Again, there are patterns that I'd love to prove. Makes me want to take a number theory class some day.

The most interesting bit for me, though, was in Set III. If we doubled our height, and stayed the same proportions, we'd double in all 3 dimensions, and weigh 8 times as much. But our skin would only have about 4 times as much area. I think we'd need to sweat 8 times as much, and would have trouble doing it. This relationship is why a bug can walk on water, or on the ceiling, because it's got more surface compared to its volume. Here's a wonderful essay on the effects of size, and a blog post on size and metabolism.

That's all for this one.
