Using slides bring more interest into the lectures. My only criticism is that he keeps mentioning things such as global warming, ozone depletion, etc. as facts set in stone, when in reality they are just theories. Very interesting course. Half notes are great - without them, it would be impossible to follow. Great slides, etc.
Textbook covers too much material.
I liked the slides and videos. It helped to be able to see things rather than just hear descriptions. Kent has made everything easy to understand. Also the half notes make the lectures much easier. It is really impressive how Kirkby gets to know the names of many of his students.
