Come with me for a ride. I'm going to start with a summary of where I am and what I am doing on each "track" of study.
Starting with Physics, I started a new track in particle mechanics before I had quite finished the last one. Right new, I'm reviewing my methods of describing position, and I've now finished the older track with a paragraph or so on quantum mechanics. I'm also working in Electromagnetism, specifically electrostatics, and I started a review of subatomic physics and took notes on the types of subatomic particle.
In chemistry, I'm taking a closer look at the elements. I may have mentioned that Hydrogen has a unique place and gets more attention than many others. In describing chemical change, it's important to look, not only at what substances are present, but how much. In local astronomy, I'm reviewing information on the sun. In Earth science, I've finished a section describing major landforms. In biology, I'm reviewing the major kinds of body organisms and systems in the Anatomy and physiology section, and on a separate track, I'm focusing a little more on concepts of biological communities.
In studies of the human body, I've been looking at muscle systems. There are too many of these for me to concentrate on memorizing all of them just yet; I'm considering only the major groups, with more details to come later. In psychology, I've finished a section on sensation. For individuals, I've done a skeleton outline of things to consider in studying the apostle Paul.
In the area of Anthropology, I'm starting another track with studies of social psychology. I should probable rename this, because on closer examination of the area I called presentation, I found that I need an area that includes the particularly social applications of psychology in general. On the other track in Anthropology, I'm dealing with Africa.
