I really enjoyed the quality and pace of this course. The weekly pace was reasonable for someone like me taking this course out of personal interest and doing so after work in the evening. The quality of the video courses was excellent but I understand that this is tied to the individual quality of the professor. Support materials (notes and problem sets) were very helpful to complement the videos. I like the structure of the course and the tool itself which I ran conveniently from my tablet. Overall great experience and looking forward to my next course.

Such an amazing course with an exceptional teacher!! I was mind blown with the way such a complicated topic was handled and taught. Einstein is properly explained and his topic of relativity is explained even better. This course has given proper respect to Einstein and has respected his views and thoughts.

The moment I hear 'Einstein', I get Mr. Larry's face onto my mind, that's how amazing and wonderful he as well as this course is. I get the feeling of learning more from him, be it any topic.

Thanks a lot for this fantastic and meticulous experience!!!!

feels great, to know about such a renowned personality like Einstein. feeling like i came closer to Einstein and his work, but more than that it i feel closer and connected to the universe. this all has become possible only because of professor Lary Lagerstrom's unique teaching skills and presentation of subjects. myself being from science background found it very easy to get hold of what is actually going, but i'm 100% positive that any person from any background can understand and successfully complete this course. thank you professor.

Before the course I had practically no knowledge on the Special Theory of Relativity and I had just the math from highschool. Now, two months later, I believe I was able to follow everything (Professor Lagerstrom is clear and careful - he takes the time needed to explain things whitout rushing, but also without becoming monotonous); I certainly learned a lot of intriguing stuff and I feel motivated to continue to study Einstein's Special Theory, to work on my math skills and to build the necessary to learn more about the General Theory.

Fabulous course. Concepts were explained in rigorous detail and hand-outs and lecture presentations were impeccable. The professor makes sure no stone is unturned in this lecture series and provides insightful analysis into the theory.

Things to improve: I would suggest a shorter course for students like myself who have previous mathematical experience. Additionally it would have been nice to get a printed certificate- after paying £38.

However these things aside- a detailed well-thought through course, ANYONE can complete. 5 stars.

Larry Lagerstrom is excellent. He speaks clearly -- and repeats concepts. He is very experienced at this, applying models to illustrate points, understanding where the student might have difficulty, and going over points to make sure we have got the idea. I realized quite early that if I did not understand the concepts of this course, it would certainly not be his fault.

I enjoyed this course. It got me to think in a different way -- stretched my brain in addition to increasing my knowledge about the specific subject.

Professor Lagerstrom does a superb job of presenting Einstein's special theory of relativity. There is a good balance of history, high school level mathematics and thought experimentation. I have been studying Einstein's special theory of relativity, mostly by reading books, for over 60 years and this course solidified the theory in my mind. I actually have two good friends named Alice and Bob, who are unrelated to the course heroine and hero. The real heroes in the course are Professors Einstein and Lagerstrom.

Studying the course has been a great and wonderful experience. The course has provided me with a great knowledge of physics. I always wanted to learn about Einstein and the theory of relativity. This course has made me learn many things about Einstein and relativity. The course was detailed oriented and very inspiring. The course instructor Larry Randles Lagerstrom taught in an inspiringly effective way. It is great that he provided guidance for further reading to learn more about Einstein and relativity theory.

Nothing but excellent. Methodic, simple, clear. Professor looks also as a calm and eloquent person with a broader knowledge of historical events. He added some flavor to the lectures, giving interesting historical points and thoughts supported with Einstein's and other quotations from that time. Historical context just enabled easier understanding and memorizing of the matter and was dosed just not to move the focus from the main goal. I can only wish that the next courses I'll attend, will be on the same level.

I found this course t be very interesting, informative, and laid out in a simple and instructive manner that anyone could comprehend the material. I, myself, have been out of formal school for many years and had zero problem getting into the material with some enthusiasm. Professor Langerstrom did a fantastic job in presenting this course in a plain and simple format that wasn't to overwhelming to the beginner novice like myself. Outstanding job! Highly recommend this course. Thank you Professor Langerstrom.

Really lovely course! I studied mathematical physics at edinburgh and we of course covered special relativity. I believe it was 2 lectures! Sort of heres the lorentz transformation and heres some calculus and some problems...there ya go. I was utterly disappointed. Now i feel i have learnt something! I took the course as I have moved flats to now live approximately 50 metres away from Einsteins flat in Bern, and i realized despite having studied physics i knew almost nothing about einstein! Many many thanks!

Excellent course and Mr. Lagerstrom is an excellent professor. The course is designed for the layperson, but I'd say some general ideas of physics/math is needed. Not that it is heavy in math or anything like that, but it helps. It took me a few months to finish it because of work related stuff, but now that I have the certificate, it feels like quite an accomplishment. Thank you, Mr. Lagerstrom for the patience and great explanations, and also thanks to the whole team behind the course. Good job!

Excellent course, covering a basic fundamental understanding of special relativity and the historical context within which Einstein made his discovery. The math required to understand the concepts are also straightforward high/secondary school level math. I took this as a refresher, having took a class back in undergrad college on the same subject and it helped me recall the core concepts of the subject. Recommended as an excellent introduction for anyone interested in physical science in general

Extremely interesting course. It is challenging but Dr. Lagerstrom's pledge to "make haste slowly" benefits students and covers the material thoroughly. The material is presented from a variety of viewpoints, which should make the concepts clear for everyone. The amount of data covered is impressive. It illustrates the degree to which Einstein had command of his subject matter. I will likely never use the information presented in this course but I'm really glad I took the journey to acquire it.

Thank you so much, I thoroughly enjoyed this course. Larry is brilliant. All the mathematics were just right for me and the historical considerations perfect for a short course. I shall continue to read through my personal 'Einstein' library. Oh and Larry I loved your 'Young Einstein' book. I am now looking for another similar style of course.

My certificate is framed and up on the wall in the kitchen. I would have liked the title of the course to have been much bigger and bolder. Thanks again.

I really thoroughly enjoyed this course. I felt that Professor Lagerstrom is an excellent teacher who made the complex much easier to understand. I particularly liked the “class notes” and his philosophy of Festina lente - make haste slowly.

In college many years ago this whole subject was too mind bending for me to approach so my education when I other directions. It is nice that so many years later I could revisit that challenge a gain a better understanding. Thank you so much for that.

Awesome experience! The complex theory is presented and taught by Professor through so many video-lectures with examples and explaining so nicely that I was engrossed totally and completed successfully in advance. There are quizzes at the end of each section - this helped me to understand the subject thoroughly. This is my best experience in online learning. Knowledge on the subject, efforts, and presentation by respected Professor is highly commendable, My whole-hearted regards to him!

Professor Lagerstrom takes it slow to approach the theory, making it available to anyone with very basic math skills. While the equations are important, building the mental model around the strange world is way more essential to comprehending the special theory of relativity, and that is where this course shines. Professor Lagerstrom will look at the same problem in many different angles, cross referencing between them constantly, making sure the fundamentals of the theory sinks in.

Maybe the most satisfying course I have ever taken. Dr. Lagerstrom developed the material in such a methodical and linear way that when I hit a point that I was having difficulty with, I could find the point where my understanding had broken and focus on the misunderstood issue. Also, something that was missing from my years of studying mathematics were the motivations that led to new concepts. Perhaps his interest in the history of science is coming through here. Thank you!

Oddly, given subject matter, this is a very old school course - professor lecturing before a white board. Yet it works! I finally understand the Special Theory of Relativity and am convinced that time dilation and length contraction are real. Course is well paced. Outlines provided for taking notes for each session are very helpful. Quizzes and tests are appropriate. Highly recommend to anyone who has ever wondered if on might actually travel to another galaxy and return alive.

Professor Lagerstrom presented Einstein's Special Theory of Relativity in a "simplicity beyond complexity" kind of way. His examples to demonstrate the principles were outstanding in reinforcing the learning experience. The historical context and Einstein's quotations throughout the course added much appreciated entertainment to the challenging content. Professor Lagerstrom's humility and care for his students were so encouraging. Thanks so much, Professor Lagerstrom!

This is truly one of the more interesting (and fun) courses at Coursera. The presenter takes the student step by step through the intricacies of understanding the special theory of relativity such that, even with a very limited background in math and physics, you will be able to appreciate the impact this theory had on scientific thinking back when it was published and how it, and its 'big brother, the general theory of relativity, shape scientific endeavors presently.

The wonderful presentation of the origin and comprehensive concepts of this special theory of relativity with good examples and problems by Professor Larry Langstrom, is beyond and excellent and would rate the best by a physics professor. I would love to attend the general theory of relativity course if run(?), by him in the future, kindly inform. I rate this course 5 stars if that's the limit of stars one needs to put for an appreciation/rating.

The teacher is excelent. The structure of the course is very good. This has been one of the best teacher I ve had in all my life. He knows very well the theory, quite understandable his explanations, he has a very good managing of the board, he made me payed atention to all he said. In the next future I would like to participate in other course he teaches, related with physics (surely he will be very prepared and do it in a very extraordinary way, like this one).

This course is the best place to learn the concepts of special relativity as a beginner. The instructor is awesome. Although he goes quite slow, it helps because the concepts in the latter part of the course are counter-intuitive and may need a bit of time to be understood. I would recommend this course to anyone who is interested in learning more about the principles of relativity. I hope to see a general relativity course taught by this professor soon!!!
