A lot of time and trouble has been invested into this course, and that can clearly be seen. There was a huge group of professionals, and each of them gave a lecture on their specialty, such as the beginning of the universe, a lecture on geology, flowers, animals, climate change etc. So, this course really covers everything. I've enrolled it because I though it would be more astronomy-based, but this was just the first lecture. However, I'm glad I've stayed, because I've brushed up some of my knowledge from biology, chemistry, and geology, and I've learned a great amount of new interesting facts. Some teaching styles were better than the others, but that is reasonable, since there's a dozen of people working on the teaching part of the course. The forums were quite alive, and they featured questions for that week's instructor. All in all, a huge recommendation for this course, and a great bravo! for the University of Copenhagen.
