Comment: The class seems to be a relatively easy class, but it can also be incredibly boring. Professor Salter is enthusiastic on the topic, but sometimes drones on. Three hour lectures are also a bore. Basically all you have to do is read the reader to do the homework, and come in for the last class to take the final. The final was incredibly hard, and most students didn't finish. If you're not interested in the subject, don't waste your time with this class!
