It is important to attend the lectures and read the readings. To help structure your thoughts, we will use the wiki for discussing the lectures and readings. You are '''required''' create to substantative comments on each lecture in the course. One or two sentences are not enough. You need to add one or two paragraphs. These comments should be added to the slides for that lecture. These comments need to be entered within one week of the lecture. Look at the comments from other students before you enter your comment. You are not allowed to reenter the same information. Your information must add to the information already there. Some example of good comments: * Often the slides sketch out a derivation. Include a full derivastion of a formula on the slide. * An clarification of the slide, adding detail that was presented in class. * Record questions asked during class, as well as what ''you'' think is a good answer to the question. Expand upon the answer given in class. * Additional material from the readings that relate to a slide. * General discussion. Is something confuding to you? You are also allowed to answer questions posed by others in the class.
