Thank you to Dr. Randles for teaching us this excellent course, for preparing all the lessons in a simple manner, he makes us see the theory easy. And thank you for teaching us not only the scientist, but also the human person through Einstein quotes.

Great course. Easy to follow and to understand. Also a great compliment to the professor for explaining the material in a clear and easy to follow manner. I have now a clear understanding of the underlying concepts of the special theory of relativity. I would really like to see a similar course on the general theory of relativity.

This course is well laid out and planned. The professor goes through step by step and makes it very easy to understand a very difficult and non-intuitive subject. The qualitative explanations are excellent in giving a sense of what the equations mean.

All in all, an excellent course. Thank you very much for making this available.

Fantastic course!!! Congratulations to the professor for his wonderful content and personal form of delivery.

While I came to the course having reviewed various other resources over the years (books and videos), I

found the course consolidated my learnings and also resolved many questions I had. Thanks too to the mentors.

A very good and extensive course giving you a solid introduction to the special theory of relativity. As a high school student I found that it started out quite slow with a bit too much on history in the first week in my opinion. It gets really interesting after the second or third week, especially for someone who loves maths.

A very intuitive course which starts from the ground basics and builds an understanding on how to jog one's brains to imagine in-depth thought experiments which help us in understanding the amazingness of our universe. Very well taught by Professor Lagerstrom who explains in a very simple manner for everyone's understanding.

Incredible. Now I can say to have learned the basics of relativity. A step by step approach with some math guided me through the field. Before the course I was simply aware of the major points of the theory accepting its conclusion bona fide. Now I got it. Thanks a lot professor. There is a reason why you teach at Stanford

Excellent course. No advanced knowledge of physics or mathematics is needed. The professor is extremely pedagogic and nice to listen to. The drawback is however a very low speed in the videos, which I beleive is good for many and of course for learning, but is a little irritating for those who have more previous knowledge.

Such a great course with a superb instructor! The pacing of the course, in my opinion, was perfect. We certainly made haste, but we made haste slowly. Things were explained in a way, that the greater understanding of the math and "philosophy" behind it came together in a beautiful manner. So happy with taking this course!

Excelente habilidad para la docencia mezclando el contexto histórico de uno de los más grandes avances de la ciencia moderna con las bases matemáticas y físicas necesarias para comprender la Teoría de la Relatividad Especial, de una manera didáctica y para todo público, no sólo para personas entendidas en física avanzada.

The course very interesting. Because it doesn't require any detailed knowledge of physics or mathematics, the material is easy to grasp. The concepts are explained very clearly and well. Anyone with the average background of high school level physics or mathematics can complete the course without any major difficulties.

Thank you Professor, your lecture is very interesting, and it is quite helpful to learn physics with a little history. I found that there are some mistakes in the subtitle, but it is not significant and I think I can understand it according to the context. Really impressive course, I hope I can see you in other courses.

“One should not pursue goals that are easily achieved. One must develop an instinct for what one can just barely achieve through one’s greatest efforts.”

The course was varied and motivating in its structure. Professor Larry Lagerstrom is an outstanding personality. It was a very enriching experience.

Excellent course. I feel I gained some insight into the core concepts of special relativity. I took to heart the "festina lente" ethos exposed early in the course by the instructor. Larry Lagerstrom is a fantastic teacher, he has the ability to explain often complex material in a way to that makes it understandable.

The best course on Einstein's Special Theory of Relativity. The instructor is very patient and provide detailed explanation. Even if you don't have any math and physics background, you would be able to understand more than 90% of the course material. Suitable for anyone who want to really understand the topics.

The teacher was incredible. Thank you! I'm young and had minimal experience with Einstein's work prior and now I can credit myself with fully understanding special relativity. I hope to do general relativity eventually but perhaps when I'm old enough to go to university as it seems quite advanced. Thanks again:)

This course offers an excellent and intuitive entry to the special theory of relativity. In my eyes, it is suited for everyone being fascinated by space-time and the "weirdness" of our universe and at the same time wants to dig a little deeper into the physical and mathematical framework of special relativity.

I don't have a very good English, but I can say that I understood it more or less, my teacher explained it very well and it made me very excited. And I just want to say thank you Coursera for offering us the best professors at the best universities in the world. It would be nice if it was in Turkish though :)

Excellent course. Despite a solid background in chemistry and maths, I have never covered Special Relativity formally. I could never remember which clocks ran faster or which twin aged more. Now I know! Course suited to anyone with a minimum of maths and a modicum of curiosity. Onwards to General Relativity.

I thoroughly enjoyed the course and it was informative and we'll presented. I think I will miss listening about time. For me its been much therapeutic. It challenges my brain to even visualize these concepts and hence I can spend as much time studying it. The presenter knows his stuff and like his simplicity.

An outstanding course, it was what I was looking for to get a good understanding of the topic.

Really good course progression, well explained concepts. I am definitely happy and "1000%" satisfied with this amazing course, Professor Lagerstrom is simply amazing and he definitely deserves a strong acclamation!!

It was incredibly interesting and enjoyable experience,the course instructor was fabulous and i could understand many mind baffling information with a surprising ease.I am looking forward for stanford university's course on the general theory of relativity and i hope that it is taught by the same professor.

A fun and engaging class! The instructor starts small and then builds each lesson on top of the last to make the material easy to understand and digest. Very little math involved, and he gives you the few formulas you need so only a basic understanding of algebra is needed. I'm so happy I took this class!

El curso es excelente. y de acuerdo a lo necesario para comprender la teoría sin ser un especialista.

Espero que en un futuro cercano completen el conocimiento ofreciendo un nuevo curso sobre la teoría general de la relatividad, para completar el aporte de Einstein a la ciencia y su desarrollo profundo.

Great Course. I wish there would me more courses like this in other topics like general theory of relativity. Discussion forum is very active. Mentors are available to clarify any topics. Videos are a bit slow though, but you can always fast forward. I am grateful to the course instructor of this course.
