Course content (General course outline) This is a basic list of the main topics included in the course. There are additional concepts, lecture topics and material that will be included. This is a central set of topics that will be studied. The list does not exactly match the chronology or sequence that will be followed in class. The actual sequence will be slightly different because I want to follow the flow of text chapters. I want to minimize hopping around the text.
