Thank you so much for taking the time to do this. The knowledge I have gained is something that I will treasure and will propel me to keep studying and trying to understand our wonderful universe.

I enjoyed this course very much. Professor Larry Randles Lagerstrom made a difficult subject easy to understand. Especially for a fellow who at 85 has forgotten a lot of what he learned in college.

THANK YOU SO MUCH PROFESSOR FOR PUTTING THE CONCEPTS IN A SIMPLE AND ORGANIZED WAY. THE COURSE IS A REAL EYE OPENER FOR A SCIENCE ENTHUSIAST! LOOKING FORWARD TO JOIN YOUR NEW COURSES AND CONTENTS.

This course is really wonderful. You will get some basic ideas related to Einstein's theories. If you are keen to know about Einstein, it's going to be your perfect start. Really excellent course.

I really enjoyed this course. Very concise, clear yet teaches a lot of mind-challenging concepts. I am so happy that I clicked the bottom to register this course. Also, big thank to the professor.

Wonderful course on STR. Mr. Larry explained the complicated things in a very easy way using lots of diagrams. I was motivated throughout the course because he kept me on track so I lost nothing.

Excellent course. The instructor did a wonderful job, using a white board and simple props. He made it interesting and made these complex principles understandable. I enjoyed the experience.

It is an excellent course. Just the right thing for a person who truly wants to understand the basics of the Special Theory of Relativity. The teaching style of the instructor is also amazing.

This is one of the most wonderful course that I have ever found on Coursera. The course take a simple and realistic approach to explain the concepts evolved in Special theory of Relativity.

It was a good introductory course for the special theory of relativity. But being from an engineering background i wished it was a bit more quantitative but an excellent course nonetheless.

This course was truly amazing and everything here was taught in a way that students can easily understand. I earnestly request Larry, sir to compile a course on general theory of relativity

Outstanding course, by far the best MOOC available. I really enjoyed listening to prof. Lagerstrom lectures and his clear explanations of a subject which is not so obvious to understand.

Easily one of the most informative courses of my life. Of course the information given was not new, but the details and L. R. Lagerstrom were really cool. I get what I expected and more/

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.

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.

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.
