Absolutely wonderful course. I am grateful to Mr. Lagerstrom for making haste slowly in his explanations during the lectures. Really helped to cement the concepts and the math into the mind. This course comes with my highest recommendation to anyone who is interested in learning about Special Relativity.

The course was challenging to me because of the math, but the examples and concepts were explained and reviewed so everything built on each other and made sense. Randles Lagerstrom was an engaging instructor. I enjoyed the brief tangents and asides, which gave proof to the narrow focus of this course.

Excellent course which explores every concept of the theory deeply. It is a very interesting experience to see the theory build up little by little from scratch.

The discussions forums are great with active mentors.

I highly recommend it to anyone interested in science and willing to take some time out!

An excellent and well presented course that patiently describes the Special theory and is easily understandable. Be prepared to concentrate and spend 6-8 hours per week to get full value from this. I think Larry is a very good instructor who makes the critical concepts very clear. Highly recommended.

F​or someone that has basic physics and maths background, this course really helped me understand more about Einstein and his work. Not too intimidating and not too easy either. Just the right amount of academic rigor for me to delve into other physics courses if I decide to. Thumbs up for Stanford!

Dr. Lagerstrom is outstanding in his methodical & structured presentation. The quizzes throughout the course and the additional supplementary questions are invaluable. The guidelines he gives at the beginning of the course hold in good stead for this course and for any others too. Excellent course.

This is one of best courses I have ever taken. Professor Lagerstrom did an outstanding job in this clear,consistent and careful introduction to what is arguably one of the most revolutionary theories of all time. I am taking the 5 stars and multiplying by a lorentz factor of 1.2 to achieve 6 stars!!

Dr. Lagerstrom has done a beautiful job in giving an in depth view of the matter in a very accessible fashion. A complex phenomenon is explained in all its detail in a very nice blend of geometry and elementary algebra, The problem sets and the quizzes make you think. I fully recommend this course.

This course is amazing!! Even a person without physics and mathematics background can understand it. Its also very help for physics undergrad students like myself. The professor explains every concept patiently and refreshes the concept before going to the next one. Every one must try this course!!

The methodology of the Professor to tech and explain this topic was amazing and helped me understand the concept which I otherwise would have never understood. I recommend this course for people from non-physics background but have keen interest in understanding the Special Theory of Relativity.

I had been trying to understand this concept from a long time and could never understood it.

This is the best course i had done and the Instructor Sir in awesome, just awesome.

I will let my daughter also take this course.

Would require a signed photo autograph of Larry Randles Lagerstrom , Please.

Great course, great teacher! It was really interesting to listen to everything during the course. If you want to learn about special theory of relativity and tired of stupid Youtube videos, that don't explain anything, follow this course. It takes 8 weeks, but it's 100% worth the time spent.

Its one of the perfect and easiest course for beginner there is hardly any math involved professor Larry did a amazing job teaching the special theory of relativity if you have an basic knowledge of algebra and prescriptive and observations in scientific terms you can understand this course

Dieser Kurs war für mich als Neueinsteigerin genau richtig. Es wurde sehr verständliches Englisch gesprochen und die Begleitmaterialien waren ausführlich und hilfreich. Im Forum wurde auf Fragen immer sofort ausführlich geantwortet. Mir hat der Kurs sehr gefallen und ich habe viel gelernt.

This is the most interesting topic I've ever learned in my life.Tons*C² of thanks to professor Lagerstrom who explained everything clearly and patiently and thanks to Stanford university too. I would so recommend this course to my fellow science enthusiasts and thanks to you too coursera.

This was an outstanding course! Professor Lagerstrom did an excellent job teaching the material in a way that was understandable. I absolutely loved this course. I have a much better understanding of Special Relativity and a desire to keep learning more about it. Highly recommended!

Very well designed course with good content and information. Also takes a methodical approach to teaching and is easy to follow and get a good understanding of the underlying concepts behind special theory of relativity with context around how it was conceived and developed by Einstein.

Great class. The professor is very careful, clear, and methodical. If you know basic algebra then you'll be able to understand everything that goes on in this course. The progression is nice and slow so that when you get to the "weird stuff" it all makes perfect sense. Highly recommend.

It's just amazing the way Professor Larry teaches. The best course I've taken so far. It clarifies many doubts regarding the Theory of Relativity. The course is very intense, there were many tests, but it was excellent, I learned a lot. I recommend it to the entire scientific community

We made haste slowly. :)

And, it helped absorb some concepts which I've read multiple times over and over but could never accept.

Despite having completed the course once, I keep revisiting the videos every now and then. It helps me further get the concepts as a part of my intuition.

Es un curso espectacular para los curiosos que estén dispuestos a hacer el esfuerzo que se requiere para entender. El profesor es claro y preciso y el curso es llevado de manera que se va acelerando suavemente hasta llegar al núcleo de la teoría. Muchas gracias! Lo disfruté mucho.

Very well built and easy to digest course, even for somebody who is very far from maths and physics in day-to-day reality. Special thank you for refresh on school maths needed for the course - very helpful. The course takes some time and thinking, but worth it. Absolutely recommend!

Great, approachable course of the high summits of the human mind. I am grateful that I had the chance to understand this (for now) - or merely to be in the position of asking educated questions - during my lifetime. Thank you, professor Lagerstrom, Stanford University and Coursera!

An excellent course! The professor's explanations are brilliant! And the exercises are well chosen and fit perfectly well the contents of the course. I cannot be happier with this course. Now I really feel I have a sound grasp of the Special Theory of Relativity and Einstein's life!

Great place to start the journey into the theory of relativity. Loved the Lectures, the Professor, the layout of the course. Being a Physics student this course seems to run a little slowly in the first few weeks but the detailed explanation of all the basic concepts was very good.
