The content is really good. The quality of the content is excellent. The instructor's pedagogical skills are excellent as well.

The only criticism I have is with the length of the videos. I feel they could be shortened. Other than that, one of the best introductory courses for Special Relativity.

I think very highly of the course, and the professor, with one quibble: The professor had some difficulty talking in full sentences, which I found frustrating and annoying. Nonetheless, I enjoyed the experience, and believe that my understanding of Einstein's theories is certainly improved.

Not much of mathematical inclination. But the Prof. is really of high standard and he makes sure that you understand everything by the end of any topic as he will run by each topic more than once. Its an introductory course but induces a great amount of interest to learn more!

Very good introductory course, clear and well designed, with a nice emphasis on the key concepts of the special theory of relativity. The mathematical background required is very light, hence the quantitative analysis of various examples and situations is limited.

A brilliant course. I got everything I wanted to out of it by the end, but one thing I would say is that it started off a little slow, particularly in weeks 2 and 3. All things considered, a great way to build a better understanding of special relativity.

The course was interesting but I dis not know I had to pay $49 to obtain a certificate of completion. I pay $50 a month to take courses on Coursera I was unaware I had to pay an additional $49 for this course. Hence the 4 start rating instead of 5.

one of the best courses that I have taken so far from Coursera (and I took a lot). Easy, step by step mathematically, engaging in particular in discussion forums, Definitely recommended to anyone who has the least interest in theoretical physics!

The course gives you a good qualitative understantding of special relativity as well as the historical context in which Einstein came up with the theory. The course is easy to engage with, even if you don't have much physics knowledge.

Love the course as its a interesting insight into the world of physics.

What i dont think was effective was the multiple choice quizzes as you could just glide through them without applying the knowledge you learned in any new way.

Very in-depth course. Really liked the prof's approach of understanding everything from first principles. But there was a tendency towards over-explanation and long-windedness in the video lectures. Giving it 4 stars.

Very in Depth for if it is your first time learning. If you have already read about General and Special Relativity it doesn't tell you very much more than what you already know. Either way it is a great course.

I disliked really slow speed of formulas derivation, simple operations like cancelling out terms are done in multiple steps. Like for children that only starting study mathematics. Otherwise great course!

Than You so much this course has really influenced my life at such great heights

It has also made me give more recognition to our Bible Family for all their great accomplishments.

Felt a bit like I was being talked down to at the beginning as he tried to tell me how to study and take the course. Got much better after he just started to teach us concepts.

I loved the course. I gained a lot from this. Want to learn more mathematics and wish could learn General theory from the same team. Thank you soo much. Great work.

Quite hard work - the topic is not intuitive, and the questions teem with the possibility of going wrong - badly wrong.

Effort is required, and is paid-back.

It's a good course to start understanding Relativistic Physics. Nothing rigorous though.

The lectures are amazingly easy to understand. Overall liked it.

I think a chapter on momentum and energy conservation would be interesting, I liked the examples and the treatment of the paradoxes, very good course.

a very thorough introduction to special relativity, as a layman, I have gained immense insight & basic understanding. Thanks prof Lagerstrom!!!!

The course was really good. But the discussion forum was not pleasant. Due to the unruly behaviour of this person named Thomas Lahn

Mr Lagerstrom has explained a difficult topic in a very understandable way. He is a true teacher, not just a lecturer. Thank you.

Nice course with very clear explanations! Too bad that I had to wait for week 4 to really start the core of special relativity

Excellent Prof , Excellent Resources. My only drawback is that prof is a bit excessive repetitive, rest everything is fine.

A very interesting course simplified to an under graduate level. it helps in understanding relativity in perspective.

It helped me getting insight of modern physics and understanding EInstein's way of thinking to resplve problems.
