POWERPOINT FILES
Following are copies of the Powerpoint files for material discussed during my lectures. These are in the latest version of Powerpoint. If they do not work on your computer, try using them at the library or one of the on-campus computer labs.
These files are not intended to fully summarize or to outline the reading assignments. They are mostly a way to organize lectures and make sure I do not forget to talk about an important topic. They should not replace studying or be used in place of the textbook.
Sometimes files are revised right before class. In that case, I will post a copy of the revised file as quickly as possible after class.
