thank you, Professor! it has been great learning all this from you. i enjoyed the journey. it was marvelous and creative and helped me reflect upon a lot of things i was once curious about as a child and as i was growing up.

I never thought that studying Theory of Relativity could be so easy-All thanks to Larry for making the course so easy, conceptual at the same time interesting.

Looking forward for your course on General theory of Relativity.

I'm a senior engineer, my job is about power electronic. I have always been interested on the Eistein's thought and I thank Coursera and Stanford University for the opportunity to discover the Special Theory of Relativity.

Great course for thoughtful minds .

Awesome lectures from gifted professor.

Great understanding of Einstein and Special theory of relativity .

Mind blowing facts, time dilation and length contraction .

And the weird paradoxes

The instructor of this is excellent and provides very good insights into the topic which is very difficult for topics like these, which is totally against our intuition. Everyone should take this course in their lifetime.

Very well Taught & Explained by Prof. Larry Lagerstrom. Thank you a lot for this effort to everyone including the Professor, the University & Coursera for such convenient & Flexible method of teaching such complex ideas.

I think this the best course for beginners who want to learn special relativity qualitatively. This course contains least mathematics. But, then also, you can learn concepts of relativity very easily without mathematics.

Excellent combination of physics and history of physics and I loved following the lectures given by Larry in his somewhat slow, but very throughout way that really made me to understand the special theory of relativity.

Prof. Lagerstorm is probably the best professor one could wish for, I am 13 and yet was able to understand in depth. His references, and explanation is so simple that it made such complex concepts easily understandable.

Really nice course, the teacher explains well and his clear. Mathematic aspects are not too difficult to understand. I really enjoyed this course and have a much better understanding of the special Theory of Relativity.

I am very happy with this course. I am a physicist and I learned too much, I think the best way to learn a theory is in a historical context. I recommend this course. I expect you open the course on general relativity.

The course was perfect in every way...I'm in 9th grade and I could understand the concept clearly all thanks to the Professor's teaching and the guidance of the mentors who cleared all the doubts!

Thank you once again!

I h​ighly recommend this course to anyone wanting to understand the ideas behind special relativity without being bombarded with maths. I wish my lecturers at university were half as good as Larry Randles Lagerstrom.

This course really explained well "The Special Theory Of Relativity". In addition to that you can also learn that how theories develop step by step, measurement. Also I got know a lot of things about Albert Einstein.

The way the course is given, clear and slow paced, makes it easy to understand the topic for someone who hasn't done math for a long time. Which was good for me since I did the course for fun and not career related.

This was a great course and Larry Lagerstrom is a wonderful teacher. I would thoroughly recommend this course to anyone interested in Einstein's Special Theory and I'm hoping that Larry will do more physics courses.

The way topics are presented is so fluid (and for the general public) that it is impossible not to follow the roadmap and conclude the course with few but very sound concepts about the special theory of relativity.

Thanks to the professor

Larry Randles Lagerstrom for this high quality course. I had exciting moments during class. It is hoped that one day humanity will become a stellar civilization ... Again thank you very much

This is one of the best course I have a taken in a while. Thank you to the Prof to make this learning experience one of the best so far, Can't imagine anyone else explaining the same material which such clarity!!!

This course helped me understanding many concepts of The Special Theory of Relativity. I recommend it particularly to high school students. Thank you very much to the teacher and all that contributed for that job.

Thanks for keeping it simple. There was a lot of head scratching; but the professor kept going over the issues with great examples. One of the best instructors I have had in 5 years of online courses.

Thanks

Great class! My favorite part was the first 3 chapters regarding Einstein's background history. I don't have much of a science background so I did get a little lost later on in the course, but I still enjoyed it!

THANK YOU PROFESSOR for your efforts, your presentation made me want to study all the physics now, I'm not finished with the course yet but I couldn't wait to thank you Coursera team, this website is a blessing !

This course is superrbbb... It gives you the best and easiest explanation for Special Relativity... also the professor's teaching method is amazing

It gave me a good kickstart in my dream to pursue astrophysics!!

Excellent course. I particularly appreciated the step by step approach with frequent stops to go back and patiently review points which may not have been easy to digest. Prof Langstrom is the perfect instructor.
