I was the black kid in school who'd skate and wrestle, who was really into outer space and botany and kung fu and hip-hop. I was into everything.

I'm a science guy. I'm a geek. I love geology and botany and marine science. I thought maybe I'd be a professional guide, or maybe even a park ranger, working for the Department of Fish and Game.

It is, I find, in zoology as it is in botany: all nature is so full, that that district produces the greatest variety which is the most examined.

The grounding in natural sciences which I obtained in the course of my medical studies, including preliminary examinations in botany, zoology, physics, and chemistry, was to become decisive in determining the trend of my literary work.

Without the name, any flower is still more or less a stranger to you. The name betrays its family, its relationship to other flowers, and gives the mind something tangible to grasp. It is very difficult for persons who have had no special training to learn the names of the flowers from the botany.

Just as the science and art of agriculture depend upon chemistry and botany, so the art of education depends upon physiology and psychology.
