THE COURSE WAS A DELIGHT! MR. LAGERSTROM WAS AN EXCELLENT INSTRUCTOR. IT WAS A REAL PLEASURE TO SIT IN ON HIS LECTURES EACH DAY AND LEARN A DIFFICULT SUBJECT. I WOULD RECOMMEND THIS COURSE TO ANYONE WITHOUT HESITATION. THANK YOU MR. LAGERSTROM FOR A TRULY WELL DONE COURSE.

Thank you very much to Professor Lagerstrom for sharing his knowledge publicly for the benefit of others. This is a fantastic course for learning the concepts of the special theory of relativity. Highly recommended if you are getting started or getting back into physics.

This course is organized very well, and useful handouts are provided. The lectures are very easy to follow clear despite the difficulties of the topic. An historical and Philosophical contest helps to understand better the arise and development of these beautiful theory.

A brilliant course presented with knowledge and passion by Prof. Lagerstrom. It is very easy with minimal dependence on Mathematics. It certainly has inspired me to follow on to learn more about the Special and General theories. Thank you for providing the list of texts.

This is so helpful for those who wanna understand our universe and who are not learning in college for that...it helped a lot for my curiosity. Thanks to sir Larry, he has put so much efforts to let us understand what is needed...again thank you Larry Sir and Coursera.

Excellent course. Prof. Lagerstrom provided detailed explanation regarding the special theory of relativity in a very simple and understanding manner. I hope to attend more courses from the good professor soon. Thank you for sharing your knowledge to us, sir. Kudos.

exceptional introductory course to review and revisit the basic fundamentals notions about the relative motion and Einsteins special relativity ,hats off to instructor for making it look simple and interesting carry on the noble cause of spreading knowledge. Thanks

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.

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.

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.

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.

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!

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.

Really great Course: though Professor Lagestrom explanations can sometimes feel being too long, he is always very clear. I really enjoyed this Course, and wish there would bea similar follow-up course on the topic of the General Theory of Relativity

A fantastic course by a fantastic teacher. Enthusiastic and interesting and most importantly clearly explaining the subject matter. I wouldn't hesitate to recommend this course to anyone and to take any other course run by Larry Randles Lagerstrom.

Very clear presentation of the Physics involved. Can be followed without mathematical background. As a suggested reading I would add "L'évolution des idées en Physique" from Einstein / Infeld"Let's go now for a lecture in general relativity!

Professor was very thorough in explaining the various aspects regarding the Special Theory of Relativity. The tests and problem sets were well related to what I learned in the videos, and helped me apply what I learned. A terrific course.

The content and quality of the course is amazing. I am very satisfied with the course director's knowledge, his ability to convey that knowledge and I now have a much better understanding of the Special Theory of Relativity. Five stars!

It's a brilliant course. Although I knew nothing about this topics, even as regard as basic Physics, I understood everything. There are simple explanations and a very didactic diagramming. This was an enriching and enjoyable experience.

Thanks for this course. And I am overwhelmed by the fact that you're giving away these course materials for free. Of course, I'll buy a few important courses for I'll be asked for a certificate. Anyways, thanks a lot team course era. :)

Great teacher. Clear message. Goes slowly though the material and highlights key concepts few times to make them stay. If someone does not want slow pace can always jump ahead as course structure is well organized and described.

O curso é excelente. O conteúdo é muito bem dividido de modo que o aprendizado é gradual e consistente. O professor é bom, consegue dar bons exemplos e contextualiza bem a matéria. O aspecto histórico é extremamente agradável.
