Almost anyone can learn about the special theory of relativity from these lectures. I actually can't believe that I studied from a professor who teaches in the USA and in so simple way. I am grateful.

Thanks for helping me understand the Special Theory of Relativity, covered a lot of ground but repeated it so it really could sink in. Like your style and want to thank you for your assistance. Thanks

This course is the best place to learn the concepts of special relativity as a beginner. The instructor is awesome. Although he goes quite slow, it helps because the concepts in the latter part of the course are counter-intuitive and may need a bit of time to be understood. I would recommend this course to anyone who is interested in learning more about the principles of relativity. I hope to see a general relativity course taught by this professor soon!!!

A very thorough and complete explanation of the Special Relativity theory. Finally a really good pedagogical approach is used to explain to plain people like me concepts that are proven for more than a century but still a mystery for most. Having very important scientific concepts explained to our society can mitigate the terrible challenges we shall confront in the coming decades.
Thank you very much to Stanford University and specially to Dr Lagerstrom.

It is amazing to have access to such an interesting, well taught class through this free app. Prfessor Lagerstrom takes material that is often considered extremely difficult and explains it in such clear and concise terms that it can be understood by just about anyone. The required math is not much beyond basiic algebra and you can come away with a much deeper understanding of the way the universe works as well as a nice look at Einstein as a person.

This was a very enjoyable and revealing course, covering what at first may appear to be a somewhat impenetrable subject. But the step by step approach and sensible progression of topics made the subject matter easily understandable, and the obtaining of that understanding a joyful and insightful experience. It can't be easy to teach such a course to camera, so big thanks to Larry Randells Lagerstrom.... he definitely deserves a strong lager!!

This was not just a course, but an experience in learning. The professor took us through a journey of learning about a topic very difficult understand, and patiently led us through the learning experience with right amount of maths and excellent use of examples, quotes etc., to keep the interest alive all through. I wonder if some such course on General Theory of Relativity can be there, even if that is perhaps more mathematical.

This course is superb! The professor explains complicated concepts and mathematical equations in the simplest manner possible. I learned a ton!
Note: the course keeps mathematics at a minimum, so if you want a quantitative approach to the Special Theory of Relativity, this is not for you. However, even if you are looking for a quantitative approach, this course will enhance your conceptual understanding of Einstein's theory.

An amazingly clear overview of the matter. The professor takes it step-by-step, religiously. I succeeded the course, but now I think I want to do it again, taking more notes, doing all the homework (which I did none). Don't rush! It's fundamentally important for your understanding of the universe.
As a reading, I recommend "A Journey into Gravity and Spacetime", by John A. Wheeler. Perfect further reading for this course.

Until I took this thoughtful, extremely well organized course, I could not get my head around many of the weird concepts in Einstein's Special Theory of Relativity, no matter how much I read about it. Prof. Lagerstrom is to be congratulated for the very excellent, logical manner in which he has taught this course. I would highly recommend this course to anyone seeking a great mental challenge and scientific curiosity.

I seriously love this course. It gave me a lot of insight in the realistic world. I love the way it is explained, it could not have been better! Thank you so much! This is the first course I have ever done, and I think I will move on towards the General Theory of Relativity. So much thanks again! This course changed my life, positively. I'm more motivated than I ever was. You are doing a great job, I love it. -Remko

As a geologist engineer, this course showed me that no modern physics can be out of reach. We all can play with these ideas and get a solid understanding of them. Prof. Lagerstrom really made the most important points clear and I got a clear picture regarding the Special Theory of Relativity, among history of science and other stuff as well. Great, solid course of which I can only feel thankful to Prof. Lagerstrom.

Wonderful course that has opened so many doors of thought and knowledge. Thanks to the professor, Larry Randles Lagerstrom for his instruction and for bringing this amazing course of one of the greatest minds of all time to Coursera. My interest in physics has been piqued and i will continue to pursue a deeper understanding after this wonderful course. Thank you again to the professor and to the team at Coursera.

This is a very wonderful course. I really enjoyed it. The professor really shared the insight of having a struggle to understand will lead to an ennobling, enriched experience and how we can look at the big picture of what the universe is like and how this works. Understanding Einstein's Special Theory of Relativity really helped a lot (in context and some key concepts of space and time). Thank you professor.

The course is a beautiful marriage of history, humanity, and science. The pace is slow at first but picks up steadily. I never thought I would ever understand special relativity but thanks to Professor Lagerstrom's thorough explanations, I am now comfortable with the concept and see the world in a different light. I wish Professor Lagerstrom will eventually produce a similar course on general relativity.

Amazing introductory Course for Special Relativity. Might be a bit too basic at times w.r.t to maths but hey!, it never hurts to listen to things for a second time. Will definitely recommend to anyone looking to get into higher level physics. Being a High School student myself, I learned a lot and thoroughly enjoyed it. Thanks a lot to Stanford and Prof for making education freely available to all.

This course is engaging and interesting. The lecturer inspires you to learn and open your mind. The course itself can be hard in areas but if you stick with it, eventually you can work it out. There is a fair bit of algebra (which I never studied at school) but I still made it! I recommend this to anyone who wants to understand time and space and be drawn into the fantastic world of Einstein.

After reading almost a lifetime books about the works and accomplishments of Einstein (not being a graduated scientist but huge fan of the topic), it is amazing to follow this this course and explore this world in a whole new sight. Fantastic stuff brought by the best instructor by far. I think I will start all over again. A lot is much more obvious now, or is it? Triple A+ for Larry. Thank you.

I can't stress enough how good this course is. It's the best course i've ever taken in any subject. It's really impressive how much energy, thought, patience, care was put here. I'm deeply thankful for this. You guys made me so happy. Almost everything someone need to know about STR is here. And the teacher... maybe my favourite physics teacher ever. This guy is the golden standard of teaching.

A very thoroughly planned and executed course. It is obvious that the professor/Stanford spent a significant amount of time in determining the content/videos and the supporting quizzes and tests. Ideally suited for those with basic math skills up through algebra but not calculus. The inclusion of the motivating historical aspects is something that is not always covered in similar courses.

This is a greate course. Many thanks to all involved in providing such a very well elaborated course, modeling such a complex subject in a "simplified" version that is reachable by many people that would be disencouraged by maths and formulas intrinsic to the subject. Thanks also to Professor LArry by making the course even more entusiastic and attractive by given many examples along it.

This is the first course I ever finished on coursera! Thanks to Prof. Lagerstrom for making the course so easy and engaging for people with any level of maths and physics knowledge to follow and pick up. I've really enjoyed the whole journey and gained knowledge about this universe. It's definitely worth recommending to anyone who's interested to know more about the world around us.

Great course. The instructor goes slow and repeats important points for maximum retention. Key equations are rigorously derived (requiring only high school algebra) but are rarely required in the weekly quizzes. After completing this course I have a better understanding of special relativity and (thanks to the final week) better understand its relationship to general relativity.

Fascinating course and a material presented in a super approachable way. Many paradoxes thoroughly explained - for the first time for me everything from start to finish was crystal clear. Amazing how almost all of these interesting phenomena, including Lorentz transformation, can be derived simply by using pythagorean theorem and common sense. Can I have a second helping please!

Very well done. I learned a lot and I'm very pleased with the results I achieved. I learned to study with purpose and to be patient in my learning. I learned to listen intently and apply what I learned. Even old dogs can learn new tricks. I really enjoyed listening to Mr Lagerstrom's lectures. He is knowledgeable and interesting to listen to. He made the course easy to follow.

This course is outstanding. I have tried other self-learning STofR courses and never got past the preliminary steps. The professor is outstanding, the amount of effort to make Special Relativity concepts understandable at the high school algebra level must have been immense. Thanks for expending the effort.

Es un gran curso, el profesor tiene una gran experiencia haciendo clases y he aprendido mucho tomando el curso, ayuda que esté el texto en ingles de sus diálogos para traducirlo si hay alguna duda. El curso cumplió todas mis expectativas, felicito al equipo que diagramó y preparó este lindo curso para los amantes de la física y la astronomía. Un abrazo a todo el equipo.
