It's a brilliant course. Although I knew nothing about this topics, even as regard as basic Physics, I understood everything. There are simple explanations and a very didactic diagramming. This was an enriching and enjoyable experience.

Thanks for this course. And I am overwhelmed by the fact that you're giving away these course materials for free. Of course, I'll buy a few important courses for I'll be asked for a certificate. Anyways, thanks a lot team course era. :)

One of the best courses I have ever seen. With only little knowledge in physics and math, it is possible to follow the course until the end. A lot of the theory is visualized in pictures and graphs to make it even better to understand.

Larry was a brilliant teacher and explained everything very clearly. He took the necessary time on each aspect of the course and made sure that the 'foundations' were laid to properly understand Einstein's Special Theory of Relativity.

A very clear and well thought-out presentation of a tricky subject. At 75 I feared my speed of comprehension wouldn't be up to it. Thanks to Larry for helping me get up to speed and for making the experience so unexpectedly enjoyable!

I have never ever had a better course than this. As a person with a little background in physical scineces, I am capable of asking important questions about the universe. Thank you Prof. Lagerstrom for your unforgettable contribution.

I got a more in-depth understanding of how special relativity acutally works and I was able to completely clear the major doubts that i had about the various pseudo paradoxes that arised out of this theory such as the twins paradox.

This was my first course on Coursera and I'm very satisfied. The journey through Einstein's world of relativity was very interesting. Thanks to Coursera and professor Larry Lagerstrom for making the course enjoyable and special.

The course was really a dream come true for me, I have got a big idea of Einstein's great works. I just loved the way, the course was formulated. I wish to be a theoretical physicist one day!!

Thank You for this wonderful course

This course is really good for the very beginners who have started studying physics. The way it has been presented is a very easy and lucid one. Although I would have like the optional problems to have much more harder problems.

Great teacher. Clear message. Goes slowly though the material and highlights key concepts few times to make them stay. If someone does not want slow pace can always jump ahead as course structure is well organized and described.

Amazing. Thank you so much. Mr Larry Randles Lagerstrom is the best teacher ever. I am not a physicist, but the subject of special relativity has always interested me, and no one has presented it in such a clear way. Thank you.

O curso é excelente. O conteúdo é muito bem dividido de modo que o aprendizado é gradual e consistente. O professor é bom, consegue dar bons exemplos e contextualiza bem a matéria. O aspecto histórico é extremamente agradável.

I thoroughly enjoyed this course and couldn’t recommend it enough. The lecturer is terrific at explaining complex topics and his Festina Lente approach was highly suitable for teaching this subject matter at a beginner level.

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.

An excellent and thought provoking course. This is the second time I have taken this course after a gap of a few years I passed the first time comfortably but so interesting was it that I did it again just for pleasure.

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.
