I have completed the training and I got the course is very interesting and very important topics and titles discussed. I got the course is very important for my future study and career.

Great course!

Thanks to Professor Lagerstrom for his patient and clear way of teaching and explaining things. Looking forward for a course on General Theory of Relativity tought buy him.

Very enjoyable. Some aspects are mind bending but the math is relatively simple algebra. The pace of the lectures is quite slow and the concepts built up gradually. Highly recommended.

I absolutely loved this course. With the most traditional white board, Larry presented the course content with hand writing and drawings in a very clear and easy to understand manner.

This was my first course and I must say that this was great! There was never one point where I did not have a lack of interest in the topic. I only wish that there was more to learn!

Simple and very elaborative. Enjoyed the Professors comments throughout the class. History plus concepts gave a good understanding of the theory and the background from which it came.

Extremely good course, which not only teaches the basic fundamentals of Einstein and his theories. But the biggest takeaway of the course is that it develops a scientific temperament.

An exceptional course. Covers all the basic things necessary to understand the special theory of relativity. It was well taught and will be interesting for anyone who enjoys physics.

This is one of the best online courses one can find online. The explanations were illustrative and detailed but not to the extent of making one bored. It was a fun, exciting journey.

It was very helpful.language used was simple . Professor Larry provided with wonderful deep insights. A truly enriching experience . Helped me a lot as an undergrad physics student.

wonderful subject taught by a brilliant teacher that makes even the most complicated of topics, easy to understand while keeping the classes engaging. A very encouraging professor!

This course has been absolutely amazing. The instructor was absolutely fantastic and it has given me so much to think about and so much excitement towards learning more. Thank you!

I really enjoyed learning about how light and frames of reference can affect time and length, and what consequences these results have. It was a well outlined and explained course.

Very well put together course, recommended to everyone who want to understand the basic relativistic concepts. Thank you professor L. R. Lagerstrom for doing such a wonderful job.

Thank you for your effort and the clarity with which you explain these topics that help us understand a great theory and the life of a genius scientist, Einstein.

An excellent courses with all material presented in a very thoughtful and systematic way. Practice problem sets are a very important addition to the course material. Well done!!!

Larry Lagerstrom did an outstanding job in presenting much counter-intuitive material. The course flowed nicely and I feel that I have a reasonable grasp of Special Relativity.

This course is really made me understand the Special Theory of Relativity, does not matter if your physic level is not that much good, with this course you only need so basics.

teacher is good course is also good i loved it.i wanted to buy a certificate but i have not enough money to buy...anywhere thanks for enroll free thank you so,much............

It is a great course, it helped me a lot in understaing Einstein's thoughts. The didatics of professor Larry is excelent. For sure, this course definitively expanded my mind.

Professor Lagerstrom did a wonderful job building a foundation in order to make this very complicated theory understandable. The course was well worth the effort. Thank you

I have been interested in relativity for years and thought that I understood it (in a general sense) pretty well - this course gave me new insights and is highly recommended.

Very clear and very well designed. I found it very easy to understand and useful to get an idea about general relativity.

Thank you very much, I enjoyed the course very much.

A tantalizing topic, a fantastic teacher...what could be better. Truly a well structured, superbly presented course and teacher. Highly recommended for the so inclined....

Outstanding course. I cannot say enough about the course design and instruction in building the foundation - piece by piece - for thorough understanding. Highly recommended.
