I had the notion that my studies of history are going much too slowly to be useful. I want to start making a commercial product. Given that smart phones are becoming so common and useful and applications are becoming so common, I want to go back to the low-level science end and begin programming scientific applications in what I will be calling the Sapience Learning Laboratory.
When I did a search on Android development, the first thing that came up was Udacity. This has numerous free courses that I can used to update and improve my various skills.
As I work through the knowledge base, there is a great deal of emphasis on physics. Many topics use this, at least indirectly. The most basic, elementary topic is particle mechanics. In order to work with particle mechanics, I need the concepts of time and space. I am taking a purely mathematical approach. Although space in reality seems to be infinite, unbounded, and continuous, for practical, computational purposes, I am dealing with small, discrete, bounded spaces. As I enlarge these in the process of development, they will begin to approximate reality. There are linear or one dimensional spaces, planar or two-dimensional spaces, and solid or three-dimensional spaces. I am also including time as if it were a space. This should get me started.
