Just once I wanted a task that required all the joy I had. Day after day I had noticed that if I waited long enough, my strong unexpressed joy would dwindle and dissipate inside me, like a fire subsiding . . . . Just this once I wanted to let it rip.
Annie DillardAll the green in the planted world consists of these whole, rounded chloroplasts wending their ways in water. If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring's center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its exact place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish's tail.
