It has been very interesting and exciting to follow this course.

It was also challenging to complete it with a quite good comprehension of the subject. However there are some concepts I'll have to review trying a better understanding.

I have really enjoyed the way how professor Lagerstrom explains the concepts in a so plain manner.

Thank you for doing it so well.

Kind Regards.

This is a truly phenomenal class. As a high school student that has just learn very basic physic principle, it is totally understandable and not too difficult to grasp. This is a perfect introductory couse for the Theory of Relativity. The meterials are great and the proffesor is spectaculer at explaning some complex concepts. Highly recommend it.

Exceptionally good course.

This is the first course I paid for verified certificate and finished in 3 weeks instead of 6. It was almost like detective novel. I could not wait to see what happens next.

Dr Lagerstrom took his time explaining everything slowly.

I wish he will do a course on general theory of relativity too.

I congratulate Stanford University and Coursera for let students have this course for free. I congratulate instructor Randles for being an excellent professor. I am completely new in this topic but I have been engrossed in it due to the awesome explanations and material. Thanks.

The professor was simply excellent: well-organized and articulate. The quizzes test your knowledge of what is taught in the lectures. My only complaint was that the textbook that was suggested ("Spacetime Physics") is now out of print.

I am really pleased to have come across such a well constructed and presented course. It was challenging in many respects but the tutor was aware of that and found the right level of detail and complexity. Thank you.

Amazing course on Einstein and his theory STR, Larry is an amazing instructor. This course helps me to complete my research about STR. Thanks to Justin for answering my all questions

A good balance of qualitative and quantitative elements. Perfect for someone who is interested in the Special Theory of Relativity but did not get enough from introductory books.

The course covers the base of special theory of relativity, as well as historical background. The course is easy to follow. The assements are easy also. Really enjoyable course !

this course gave me more curiosity about einsten, (even though I haven't completed it yet :)) if you are interested in einstein and his theory, I suggest you take a look

If you have no idea of relativity and wanna get a good foundation this couse is perfect. Thanks, Coursera, Stanford and especially Professor Larry Randles Lagerstrom.

Each concept is lucidly explained with full context given behind each contest. Recommend everybody to give it a try!!

Es un curso largo y lento pero permite aprender los fundamentos de la teoria y retenerlos para siempre. Buen curso.

got to know a lot with concise and yet detailed explaination with simple requirements of mathematics and physics.

thanks a lot, all credits to Dr.Larry Randles Lagerstrom and Coursera team

Easy to comprehend for people with non-science background. Great course!

Interesting course. Professor is thorough and explained it brilliantly.

I just happen to think that Larry is a splendid lecturer, (as it were)

Great course - well structured, and expertly guided.

Amazing course teaches a lot about the universe.

The most complicated theory was made very easy.

it is a very interesting and unique chapter

I like the way the instructor explains.

wonderful!! more than as expected

Good place to learn
