though i have read lots of popular physics before, nothing ever explained lorentz contraction and time dliation like dr lagerstrom! really helpful new understanding.

Great course, a little hard to follow at times. The lectures where excellent and very informative.

WOULD DEFINITLEY TAKE ANOTHER COURSE GIVEN BY THIS PROFESSOR!!!!!

Excellent from start to end. Maths level required is very basic and still possible to understand only with words a lot of things that would seem complicated before!

Provided a very beautiful insight into non-intuitive concepts and the struggle to understand the marvelous structure of reality was indeed an ennobling experience!

Me ha servido mucho.

He comprendido de que se trata cuando hablamos de Relatividad Especial

De como llegamos a las paradojas y como salimos de ellas

Gracias Profesor

IT WAS A WONDERFUL COURSE. THANKS TO CALIFORNIA UNIVERSITY AND THE PROFESSOR DR. LARRY LAGERSTROM FOR DELIVERING THE COURSE IN A VERY SYSTEMATIC AND JOYFUL MANNER.

Great course for whoever wants to understand the theory of relativity in a simple way thanks to the great course structure and explanations from Prof Lagerstrom.

Una excelente manera de aprender por primera vez la teoría de la Relatividad, me parece que cualquier amante de la ciencia, del conocimiento lo debería realizar.

A wonderful course that will enable literally anyone, even without any sort of mathematical background to grasp the idea behind the Special Theory of Relativity.

This course is excellent. I want to know and learn about Einstein's special theory of relativety. This course tech me everything about it. Sir Thank you so much.

Great course!

Mr. Lagerstrom thank you very much for giving us your insight about Special Theory of relativity and more generally for your learning initiative !

A great course for beginners. While it does not cover a large number of topics, the ones it does, it tries to do slowly, thoroughly and with clarity of thought.

Very methodical & lucid way of explaining the concepts. Understanding of Special Theory of Relativity made relatively easy, pun intended! Thank you Professor...

It was a great experience to learn such fascinating things in such a beautiful way, I believe it increased my eagerness even more towards this beautiful topic.

Fully Packed with knowledge !!. Best Course for First year students in physics and general people who are interested in physics and with no background in math.

Very formative for those without mathematic knowledge. It addresses the key concepts of special relativity at a very reasonable and undemanding pace. Thanks!

It is a great course for anyone who wants not only to learn the theory but to understand it and how it's creator Albert Einstein came to these discoveries.

Best course to understand the basis of the Special Theory of Relativity, mainly for such guys who mean to understand this theory only by using mathematics.

A superb course that goes into an excellent amount of detail on the Special Theory of a Relativity, with well paced and engaging lessons and problem sets.

Very pedagogic course on a fascinating subject that is not well understood by non-physicists, even though it is considered as scientific general knowledge

Thoroughly planned and thought-out course. excellent presentation, no technical issues; has a strong impact on the mind. wonderful course in all respects.

An invigorating course that provides foundational understanding of the core concepts and theories in physics and Einstein's ingenuity. Highly recommended.

Excellent mid-level course with the right amount of math. Instructor was highly knowledgeable and presented the material in a very understandable manner.

Excellent, thanks to Coursera, for allowing me to do the course, it's nice, it helped me and I learned new skills, I was nurtured from the course, thanks

It is one of the best course on this topic I followed. The presenter is a very good pedagogic and speak a very pleasant English for non native listeners.
