To try to compress the universe in only a few lessons is incredibly hard so we can only say this is an introductory course. I hope other courses are developed to explore this subject more deeply.

Wonderful course! A brief introduction to cosmology but with plenty of material to cover. I recommend researching for papers additionally to the material, but you'll need more time than 4 weeks.

Excellent course for beginners. just one issue: the audio is very soft and is often hard to hear even in full volume. it would be appreciated if the audio could be increased a bit

Requires some knowledge of physics to do calculations. Concepts are well explained (with examples and graphics) so that anyone can understand the material otherwise.

Some of the problem calculations should be given in handouts, or listed as a prerequisite. Otherwise, great course.

Videos are taken from classes in the university and sometimes not really clear.
I have found few questions in the Quiz whose subject has not been covered in class.
The professor, during the class, too often asks questions to the audience and that does not give any benefit to the student here.
I honestly regret having applied to this course.

I have been interested in celestial bodies since I was 3-4 years old. Why are they there? Why were they formed? Why do these objects shine? My greatest desire was to become an astronomer. However, I could not become an astronomer. Of course, I'm very sorry. I will be 27 years old, I studied another specialty, but I still can not give up astronomy. I'm still reading, learning, interested. I feel happy with Astronomy and live with its love. I hope that one day I will become an astronomer. One day I will be able to study the information obtained by giant telescopes at the observatory.
I love science because it does not discriminate between people. Even if scientists from different nationalities meet at a conference and do not know each other's language, they will be able to understand each other with the help of a simple mathematical formula. This is the power of science. I know very little English, so I studied the course with subtitles. My physics is weak, but in general I understand Astronomy. This course repeated what I know. It taught me what I did not know. Caltech - Thank you. Thank you both for your progress in Astronomy and for organizing this course. Especially Pr. Thanks to S. George Djorgovsky.
P.S. Sorry for the mistakes in the text.

Without a doubt, what makes this course great is the instructor. He has a talent that most professional scientists do not, he can explain concepts in no nonsense, simple terms but still cover the key details. Similar to how someone like Feynman could do. In addition, I find his somewhat dry, sarcastic sense of humor very funny.
Regarding content, it seems like it's more of a basic astrophysics class than a vanilla astronomy class....i was a little surprised about the absence of coverage about the planets of our solar system . But, on the the flip side, the course does try to hit on all the basic physical concepts underlying the universe....from the big band onward!!!!

Professor Djorgovski was amazing and this course was very well presented . Though I came to the course from a Biology and medical background, the presentation was done in a fashion that has generated a great amount of interest in this field and I plan to pursue more courses in this field.

Excellent course! Got to learn a lot. It became a little difficult to grasp by the end but by studying again and reading the previous material I was able to understand the concept better and better. The professor is amazing. It was an overall wonderful course. Proud to have completed it.
