Tree Structure

            Modern Physics 1 is structured like a tree with the more basic concepts located on the lower branches and the more advanced topics on the higher branches. Unlike the linear approach typical of most textbooks, the tree structure presents the information in a parallel format allowing you to explore each topic freely to whatever depth is desired.
            Because the more fundamental concepts are located on the trunk and lower branches of the tree, you can remain there to avoid complications, details, and rigor while learning the basic principles and reviewing the important material. As you gain familiarity, confidence, and experience you can proceed to higher and higher levels of knowledge. As you climb higher and higher into the tree you will acquire a better and better understanding and appreciation of the subject.
            If you are not seeking college credit for the course, you are free to explore any of the branches as far as you wish. Obviously, you do not need to explore every branch to every extreme unless your curiosity leads you to do so.
            In order to limit the amount of material in the course, the upper branches of the tree have been trimmed appropriately. If your interest in a particular subject lead you beyond the limit of the tree you will have to pursue the subject on your own. Either look up some of the references mentioned in the course or read a more advanced book on the subject.
            If you are taking the course for college credit, you also do not have to follow every branch to every extreme. Some of the branches are to provide background information, others are to explore interesting and optional applications of the subject, and others are to provide a more rigorous foundation for those who are interested in technical details, mathematical proofs, and/or theoretical limitations. The Syllabus for the course will tell you how far along which branches you must proceed in order to obtain credit for the course.
