You know what, it's not that complex.... it was never that complex...... humans are missing something very basic, elemental, kinda stupid thing I guess. Humans need another stupid.

a novel perspective on the subject by a master of the subject -- the course itself needs more attention though; transcripts are messy and tests have typos

Caltech needs to add few more videos other than the class hour recordings plus detail resources for the assignment which can be matched with it.

Excellent course, although the math was a bit overwhelming. I however achieved my goal of gaining a broader understanding of the universe.

At first, I was skeptical and it took me a lot of time (and I hated it), but then I speedran the 5 last weeks in 3 days and I liked it.

In general it's fine, but I'd like to see more questions with calculations, such tasks help better understand the topic

This is the third or fourth time I've reviewed this course but it still keeps asking me to

Great course, contents are very accurate and comprehensive, explained in a simple manner.

Course with deep notions. Prononciation can be difficult to understand.

Very knowledgeable instructor. A wealth of information in this course.

Exceptional for an intro course to astronomy,cosmology,astrophysics

good course. good content

speed it up to 1.5 - 2 x speed

I have really appreciated this course.

I found this course very interesting.

great course for physics enthusiasts

covers a lot of ground in short time

Great Content! Very recommendable.

Requires more reading matterials

It is good for biggners

Very nice!! Thank you!!

good course

There are number of positive things about this course but...

I'm only going to say about thing I don't like about this course;

1. Slide presentation; yeah it's now a norm but in slide presentation large amount of information flashed in your screen which is hard to track; there are some adventages of slide presentation but I prefer blackboard.

2. Derivation are not shown and that might be the reason you find it boring after some weeks and I'm not satisfied with the knowledge I am getting without derivation.

This course was very informative, but know that you definitely need to have some prior knowledge in physics. As a high school sophomore, I hadn't taken any prior physics classes and the class was extremely difficult. While I was ultimately able to complete the course and get a certificate, each week took much longer than advertised and it was very challenging. However, this class taught me about many interesting aspects of astronomy.

Very useful and interesting course. It gives scientific answers to a lot of questions. The only drawback is that it does not offer a certificate and I believe that this is very important because it is the only one that gives this type of information about the universe.

Awesome course! Intensive learning. I recommend a few studies of astronomy before take it.

There are some issues with the feedback of others proffesors
