Good and clear explanations. At the end it became more difficult since filosophie was involved which for me opened my ey. Some 'slides' are old fashioned.

Sometimes the videos are poorly edited, and the semi relevant videos last for much too long, but I learned a lot and it's a reallly good course!

Loved the course, Dr. Chris Impey is perspicuous in his lectures. Wish I had taken coursera classes when I was a student when I had more time.

Very nice. Something to improve: mix quizes with videos and not all videos first and then the quizes
