Course goals for Physics 9B Every good course should have a lasting impact. It should change the way you see the world and change the way you think. You must be prepared to think and to learn to think in new ways. This requires work, time, and practice. The material is new to you; expect to be confused a lot of the time. Confusion is good. If you are not confused some of the time, you probably are not thinking enough. Then with more thinking, understanding improves. The goals for the course include learning some specific physics topics: waves, optics, thermodynamics, statistical mechanics, and fluids. In waves and optics, a common theme is the way that waves add via the superposition principle. This leads to many fascinating phenomena including interference, diffraction, and beats. The sections on thermodynamics and statistical mechanics end with the deep concepts of entropy and the Second Law of Thermodynamics. You will see that the Second Law is fundamentally a probabilistic statement that becomes a virtual certainty for macroscopic systems. In learning about these topics, you will get a deeper understanding of how the physical world works. While this is satisfying in itself, it is also the foundation for more advanced and specialized courses in science and engineering. But there are also more general goals for this course that transcend the particular subjects covered. Develop improved problem solving skills: Translate a verbal or written statement of a problem into a mathematical representation. Select appropriate tools to use. Follow through with an argument or calculation. Improve written communication skill: Learn to make a clear, complete, and logical presentation. Learn that facts are only the raw material of learning. Improved understanding and higher levels of thinking are the larger goals. These do not come from memorization. Improve thinking skills: Problem solving. Analytical ability. Critical thinking: is an argument that is presented correct? Synthesis: combine ideas to solve a problem. Independent thinking: Figure out how to solve a problem and develop an understanding of it yourself rather than copying methods you are told. Creativity: Figure out your own unique way to solve a problem.
