I didn't have time to take the high school physics course, "earth and space science", nor have I had the opportunity to take earth science or astronomy in college, so what I know about these subjects I've picked up in independent study and reading. As I grew up in Arizona and lived in Utah, and had opportunities to see the various landforms that fascinate geologists (such as the Grand Canyon, Monument Valley, Zion National Park, Petrified Forest, etc.), I've always been mildly curious about how these things formed. And I've always liked chemistry. It's only in the last few years that I've taken the trouble to dig into the chemistry of rocks and minerals.

In physics, I've made progress from considering rigid body mechanics into non-rigid mechanics, and from magnetism into optics. In Earth science, I'm moving from minerals to rocks. In psychology, I've moved from early consideration of what I call mentation into behavior. I refreshed my memories of Gutenberg, Columbus, and Newton. I have moved from early consideration of literature to a closer look at graphics, and from occupations into sports and games.
