Great course, highly recommended. Very engaging instructor (at 1.25x speed at least), fascinating topic covered in-depth.

I really enjoyed the organization and structure - the quizzes were effective, and the handouts were a great way to keep my thoughts organized.

This is the course for everyone who is interested in understanding the theory of relativity. It breaks down a relatively complicated concept into suitable chunk sizes, such that people without much physic or math foundation can still pick the knowledge up easily.

I enjoyed a lot the course, knowing very little about relativity, this course explains me in a very gently manner the principles of special relativity, it is an excelent choice for beginners who wants to learn and for people with background who wants to remember.

Great Course for those who want to study the basics of special theory of relativity qualitatively, without scratching their heads too much. Math involved is of higher secondary school level and shouldn't be a problem for people with a non mathematical background.

Ennobling experience as Einstein said in one of his quotes. Thank you Professor for making things so simple and interesting. I was struggling to understand these key concepts of relativity from a long time. Would definitely join other courses similar to this one.

The course explains the Einstein theories in common words and language. Of course there is limited mathematics to make you feel convinced of the correctness of "Special Relativity". I enjoyed the lessons and course by a terrific teacher and professor. Thank you.

Outstanding course. Many difficult concepts were elegantly and well explained by Prof Lagerstrom. I am glad that I took this course and learnt this important reality of our physical world that so few understand even though the knowledge is over 100 years old.

Grateful for the opportunity to access an extraordinary online University course. Larry make easy, simple and inspirational every little step taken towards Einstein's mind, theories and talent . Fresh air for an already one century old insights. Thanks indeed.

The course deals with one most exciting theories in the world of science and having taken it, I can say that it is molded so as to imbibe curiosity in the minds of the most basic man with the least exposure to science. Great job by Professor Larry and Stanford.

Thank you Larry Randles Lagerstrom for the exceptional course delivery. You made it look simple, interesting and fascinating. I enjoyed every second of it.

For sure I would like to explore it further and I will use the materials recommended. Excellent course.

This was very good course and very helpful in increasing deep understanding about relativity although i have read relativity in my graduation and postgraduation already but the way it was taught here was remarkable

Thanks for providing such great content 😊

This is an amazing course. It could have used some graphics or animations, but the math and diagrams done on the whiteboard were really nicely done. I came to actually understand the Special Theory of Relativity. You need to know some algebra to get this.

Excellent course! The instructor speaks slow, so I adjusted the speed to 1.25x. But that is his motto: Festina Lente. And to be honoust it is a very abstract course, so that some items were told two or three times, makes even the hardest parts understandable.

Well, this course requires as many time as you need to remember all the details about the Einstein's Theory, otherwise you'll learn so many about our nature even if you master, I think you can emphasize some things as well. Don't forget, all is invariant. :D

Very thorough approach to the special theory of relativity. I can now understand how Einstein ended up to this theory. Doing the exercises helps a lot in memorizing and understanding the concepts. This course enlighten the ideas behind the formulas. Thanks.

I have always wanted to understand how relativity works and how did Einstein go about developing this theory and this course provided a brilliant opportunity and the professor delivered this a manner that allowed me to understand the process and the theory.

A great course!! I have learned a lot and finally understood the main concepts of relativity. It would be great if a course of general relativity could follow this one. (Although it would be probably very difficult to mantain a basic, intuitive approach)

Great introduction to Special Relativity! Good for beginners. The math is highly simplified to an intuitive level, which gives great confidence to people (like me) who don't know calculus (yet) and thus do not (for now) understand the original 1905 paper.

The Professor is great, truly the best, thank You so much. I am a tourist guide of a Tour called " Einstein in Prague" (1911-1912). Thanks to this knowledge I will be able to explain a lot of interesting principles and paradoxes to my groups. THANK YOU.

Es un curso excelente. El profesor es un docente con conocimientos y mucha experiencia.

Su doctorado en Historia de la Física da un contexto único, a aquellos momentos importantes en la trayectoria cientifica de Einstein. Agradezco mucho los aprendizajes.

A superb introduction into Special Relativity. A great way to assimilate in full the fundamental concepts before diving into a more technical/mathematical approach... if you really need it. I'm very pleased having decided to take it. Thank you very much!

This is an excellent course even for those of us who have some understanding of these concepts. The instructor is extremely knowledgeable and reinforces these ideas in a clear and concise manner.

I found it to be very thorough and interesting. Thank you!

Dr. Lagerstrom's presentations were detailed, clear, and very understandable. His whiteboard work was very good. The presentations on were neat, clear and very readable.

In my opinion, the course was a top notch introduction to Einstein and relativity.

It is a great course for all Physics Enthusiasts and also for someone who wants to know about Einstein. Prof. Lagerstrom is a wonderful teacher who helps you to imagine every single thought experiment in a very intuitive way. Thanks to Prof. Lagerstrom.

I like this course and i learn something new and very weird things about universe. I also thankful to Prof. Larry Lagerstrom, and Stanford University to provide such valuable knowledge and also thankful to coursera to provide such platform for learning.
