An excellent courses with all material presented in a very thoughtful and systematic way. Practice problem sets are a very important addition to the course material. Well done!!!

Larry Lagerstrom did an outstanding job in presenting much counter-intuitive material. The course flowed nicely and I feel that I have a reasonable grasp of Special Relativity.

This course is really made me understand the Special Theory of Relativity, does not matter if your physic level is not that much good, with this course you only need so basics.

teacher is good course is also good i loved it.i wanted to buy a certificate but i have not enough money to buy...anywhere thanks for enroll free thank you so,much............

It is a great course, it helped me a lot in understaing Einstein's thoughts. The didatics of professor Larry is excelent. For sure, this course definitively expanded my mind.

Professor Lagerstrom did a wonderful job building a foundation in order to make this very complicated theory understandable. The course was well worth the effort. Thank you

I have been interested in relativity for years and thought that I understood it (in a general sense) pretty well - this course gave me new insights and is highly recommended.

Thank you so much to the brilliant instructor who explains my favourite topics scientifically. No words are enough to thank you, sir. I learnt a lot. Thanks to the Coursera.

Very clear and very well designed. I found it very easy to understand and useful to get an idea about general relativity.

Thank you very much, I enjoyed the course very much.

A tantalizing topic, a fantastic teacher...what could be better. Truly a well structured, superbly presented course and teacher. Highly recommended for the so inclined....

Outstanding course. I cannot say enough about the course design and instruction in building the foundation - piece by piece - for thorough understanding. Highly recommended.

This has been the most professionally made course I have taken to date. Larry Randles Lagerstrom's attention to detail and clarity in his teaching was unmatched, thank you!

It was a truly amazing and informative course. The extent to which it widens one's knowledge and intuition towards any approach in physics is admirable. Highly recommended.

The course was fantastic. It helped ma a lot to learn about special theory of relativity. The way of teaching was easy and good. Thanks for providing the great opportunity.

Very good instructor, knowledgeable, coherent, understandable, enthusiastic; course well organized, well paced; interesting subject; I learned a lot and enjoyed experience.

I am a second-year undergrad student. This is a well organized introductory course and I really enjoyed learning something new. Will definitely recommend it to a friend. :)

An excellent course for those who want to have a basic understanding of the special theory of relativity without the scary math that one usually associates with the theory.

So very glad to have taken this course. Professor Lagerstom was an excellent lecturer, making this challenging subject understandable and interesting. Thank you so much.

It was an amazing Course. I really enjoyed the Course and understood the concepts of the Theory of relativity. The weeks were really well-thought and add up to each other.

Fantastic course! Really encouraged me to go study Physics at University. Really well explained and completely sparked me enthusiasm. So thought provoking and interesting!

Overall, I thought the course content was very interesting and I really enjoyed learning more about Einstein and theories about time dilation and other related materials.

Awesome course and professor did good job of explaining. Might have to use youtube or outside sources to help grasp some of the topics but great course and learned a lot

Amazing course that makes your mind opened for imagination in a magic Einsteinal world with a great instructor who simpliphy every tiny information.thanks alot Dr. Larry

Really interesting course, Prof L Lagerstrom is extremely good at teaching the concepts in a comprehensive way ; I hope that he will give more courses in the future ! :)

Very good, easy to follow course. Concepts like time slowing down and things becoming shorter at high velocities are no longer a mysterie to me after taking this course.
