My first degree came years before my second. I had wanted to be a physicist, but I flunked calculus.

So when I got out of the military, I went back to school in biology, and earned a biology degree at the University of Texas, and then did some graduate work in it.

There is simple ignorance, not knowing, and willful ignorance that refuses to know, that covers the light of knowledge with the dark blanket of bias.

I love biomedical science, I love astronomy, and you can't really do much with those in a fantasy setting.

I can become very emotional about math, although I'm not that good at it.

My personal feeling about science fiction is that it's always in some way connected to the real world, to our everyday world.

Most eyes have more than one color, but usually they're related. Blue eyes may have two shades of blue, or blue and gray, or blue and green, or even a fleck or two of brown. Most people don't notice that. When I first went to get my state ID card, the form asked for eye color. I tried to write in all the colors in my own eyes, but the space wasnt big enough. They told me to put 'brown'. I put 'brown', but that is not the only color in my eyes. It is just the color that people see because they do not really look atr other people's eyes.
