How Things Work

[There's pentagons in my bokeh! (because the aperture is formed by the diaphragm which is composed of [so I've learned] five overlapping leaves and for some crazy reason, when light passes through it, somehow [but how?? Something is missing here] pentagons are made in the highlights in the unfocused areas)]

Leaves. And Pentagons.



it's a little-known fact that I took two plant biology classes on my way to a degree in economics. I loved the first one, and took the second without the highly recommended prerequisites because I just couldn't get enough of plant biology. These little diagrams of the cross-sections of leaves make me smile almost as much as the leaves themselves. As the chlorophyll degrades, it becomes colorless, and then you can see all the yellows and oranges, which were there all along. The reds and purples are made separately and appear at certain times in the tree's development...
