Dr. arnold delivers a course that is both interesting and current. The topics that she chose for this class are not addressed in any other classes that I have taken. The work is challenging, but she makes it interesting. This is one of this classes that you do not mind attending, because you know you are going to learn something usefull in every class. The topics assigned are so interesting that you actually find yourself paying attention to the powerpoint presentations and films. One thing that she does is bring experts to a particular topic to give presentations and to give a human prospective to the subject. It is like washing the discovery channel !!!
