Thanks for helping me understand the Special Theory of Relativity, covered a lot of ground but repeated it so it really could sink in. Like your style and want to thank you for your assistance. Thanks

I enjoyed every bit of the course and cannot stress how much I appreciate the work that went into this. I especially like the lecturer; Larry Randles Lagerstrom, and how he was able to execute such perfect teaching as well as sticking true to the the saying 'festina lente'. This course has managed to drive my curiosity and engage me thoroughly. In fact, time went by so fast during the course that I wonder if the effects of special relativity somehow managed to play a part in it. I started the course with the hopes of learning something new but it wasn't the outcome I loved the most it was the struggle and the journey to get there. Big props to the University of Stanford for making this a free course. I rate this a 5/5

Great course! Well structured, builds up prerequisite concepts nicely, and ties it all together well. Dr. Lagerstrom looks at the ideas from different perspectives: conceptually, diagramatically with space-time diagrams and quantitatively with Lorentz' transformation. The multiple representations supplement each other and reinforce our understanding. In the end, I was able to finally get a good grasp of the basic ideas of special theory of relativity, which was a lifetime goal for me. And wrap my head around the "paradoxes" that are its consequences. These paradoxes made no sense to me in the past, but they did during this course, and it was a joyful experience. Just glad I found the course and completed it.

Great experience! I watched dozens of videos regarding special relativity but failed to understand. This course led you step by step with patience and you will have your big bang in the week 3rd. If you can pass week 3rd, you will probably grab the course successfully. My confusion is about the speed limit of light and the concept of relative speed. I raised my questions probably over a dozen rounds and Mr.Larry always give me help with 24 hours. What a great help. My suggestion to the course is : Please add a little bit more about relative speed. Can relative speed exceed C? Because such concept is crucial in my view to go through WEEK 3rd. A/w, great experience and Solute to THE TEAM. Thank

Literally the BEST course I've ever taken online! Perfectly structured, very detailed, very accurate and informative. I am a dozen steps closer to my dream of getting properly educated in the field of physics and the realm of exact sciences about the Universe. I enormously admire Prof. Lagerstrom as he's obviously put a lot of effort in preparing all necessary materials, making it all vivid and human with the help of quotes, stories and remarks about Einstein, always making sure the students understand the material and receive and remember it logically structured. Prof. Lagerstrom seems extremely charismatic and engaging to me, I regret this is the only course of his on Coursera. Thank you so much!

Thank You Professor Lagerstrom, the course is outstanding. I loved the way the course was taught, everything was linked to real life situations and easy to follow. At first I felt that the course was going a little slow but then I realised that a solid foundation is absolutely necessary in order for future understanding. If you skip too much of the first part you might lose some insight and not capture the fundamental ideas. I strongly recommend this course, specially for those who aren't too sophisticated with maths, since this course does not rely on mathematical derivations, but rather on diagrams, thought experiments and logical reasoning. It is definitely worth of 5 out of 5 stars.

The tutor is excellent, the pace of the course is good, the material is sufficient and everything proceeds logically and succinctly. Lots of interesting ideas and context. Understanding Special Relativity, objective met.
I was surprised to learn that the idea follows from some simple premises and so anyone with an interest can follow along qualitatively to appreciate the idea. Math ability is not essential but a modest ability I suggest would help to follow along. For anyone who wants more, and has the time, there is plenty of optional extra study material to work through.
I will return to the course in a few months and review the material as there is a lot to take in.

I thoroughly enjoyed this course. The video lectures are excellent with the material presented clearly. The pace of the course is just about right - the content is delivered fairly slowly and deliberately which is understandable given the thought-inducing nature of the concepts presented, especially for those unfamiliar with Einstein's theories. It's been a while since I've done any mathematics during my higher education days when and was very happy to rediscover some of this and to find the level needed not overly difficult.
Thanks to StanfordU/Coursera for offering the course, and to Larry for a great learning experience!

An excellent educational experience. This course is designed for people with an interest In the topic with the main prerequisite being a familiarity with high school algebra. it is a wonderful exploration of Einstein's Special Theory of Relativity that will leave you with a general understanding of the underlying concepts and their implications. Larry Langerstom's teaching style is well suited for the material presented, especially for non physicists and engineers. He takes his time explaining key concepts and this allows the student to grasp the foundational material necessary to better understand Einstein's Theory.

Clear and detailed introduction to the Special Theory of Relativity, including deriving the basic formulae involved on the topic, and advanced work made optional but available for most weeks' topics. The basic introductory analogies are simple to follow along but stunning in their implications, such as the famous light clocks not only in Alice and Bob's frames of reference but also in an elevator to touch upon the General Theory of Relativity at the end. After being a physics and relativity geek all my life, this course actually crystallized relativity and I finally understand precisely the strange effects of the theory.

Thank you Prof. Larry Lagerstrom! This course has been a great experience. Having a background in Banking & Finance, I was not sure to have the proper skills to go through such a complicated topic, which has always fascinated me. The structure of the course is perfect, the explanations are very clear. I appreciated introduction, summaries and handouts, quotes and real life examples. I also find it very effective that the teacher writes on a whiteboard instead than using slides. I would really suggest everyone to take this course. It helps understand, as was mentioned in the course, "the marvellous structure of reality".

A really excellent course - some difficult concepts ( for me at least) covered with great clarity. It's been many years since I sat in a maths class but Dr Randles Lagerstrom explained each step very clearly . A very good basic couse for anyone wanting to have a deeper understanding of the interesting and strange effects of relativity. Well organised and a lot of effort and time put into making it so enjoyable. It challenges sufficiently to make it interesting and just enough to stop you giving up! Made me want to go further... the course finished too soon - I wanted to learn more!

This course was my first course on Coursera. It was an amazing course whereby I came to know the underlying principles of the Special Theory of Relativity and understood the nature of Einstein's genius. Professor Larry is perhaps one of the most influential teachers I have come across. His way of teaching is excellent and proficient. This course has not only developed my foundations in the understanding of physics but has also made a profound impact on me. There is no better way to put in words what I have learnt in this course than requoting Einstein's quotation, "Festina Lente".

Excellent class on the Special Theory. The instruction was clear and methodical which made for a good understanding of Einstein's theory. Enjoyed the quotes of the week by Einstein. The phrase "leading clocks lag" is forever stuck in my head and I can recall the Lorentz transformation as well. The analysis of the Twin Paradox 3 ways was especially good, but this came later in the course so that the required tools could be taught first. Included a brief dip into the General Theory. Highly recommended if you have a desire to get an in-depth understanding of the Special Theory.

I had just completed my Indian Grade 12 exams and decided that since Special Relativity was something I wanted to learn about, I should go ahead and do it. I chose this course and have no regrets whatsoever. Prof. Larry explains everything in the simplest way possible and avoids complicated mathematics wherever unnecessary. After finishing this course, I have a very good idea of how Special Relativity actually works and it will immensely benefit me given I am planning to major in physics in college. Anyone who is even remotely interested in doing this course, just go for it.

Having no physics background other than self-taught, I have to say I was thrilled by this course. It was just the right level, focusing on concepts and being walked through some very consumable math (algebra level). Just the right level of challenge, with support in the forum when questions arise.
The instructor is awesome! Methodical and very cognizant of the fact this is a course for beginners. He walks you through everything step by step.
I highly recommend this course to anyone interested in gaining a more firm understanding of what the Special Theory is all about.

Amazing course. At first when reading the courses description I thought it would mainly be about Einstein's history. But I gave it a shot. Other than the first week which gave me an introduction to Einstein's life, the next 6 weeks were about his special theory of relativity. The explanations were understandable and the way in which the course was organized was impeccable. One thing I loved about this course is that Professor Larry, would give us an outline of each of his lectures. This made it extremely easy to take down notes and better understand what he was teaching.

I found this course very stimulating in terms of thought experiments and conceptual understanding—a good deal of brain rewiring was necessary! Though I wished the quantitative approach was pushed a little farther (e.g., using matrices for the Lorentz transformations, and getting into Maxwell's equations when it came to the invariance of the speed of light), it was not a prime goal of this course to rely heavily on "advanced" mathematics. Thus, I still think it deserves five stars; I definitely recommend it as an introduction to the special theory relativity! :)

Great introduction course. The teaching skills of Prof. Lagerstrom are really great. I studied a long time ago relativity (special and general) and this refreshing course was in some ways better than the one I had at the University. It does not require any high mathematical skills. I particularly appreciate the historical surrounding of the theory clearly highlighting how ideas and theories grow (not at all as usually explained in school). I do hope Prof Lagerstrom will pursue his teaching with general relativity and/or maybe a course on quantum mechanics.

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.
