This course is well laid out and planned. The professor goes through step by step and makes it very easy to understand a very difficult and non-intuitive subject. The qualitative explanations are excellent in giving a sense of what the equations mean.

All in all, an excellent course. Thank you very much for making this available.

Incredible. Now I can say to have learned the basics of relativity. A step by step approach with some math guided me through the field. Before the course I was simply aware of the major points of the theory accepting its conclusion bona fide. Now I got it. Thanks a lot professor. There is a reason why you teach at Stanford

Excelente habilidad para la docencia mezclando el contexto histórico de uno de los más grandes avances de la ciencia moderna con las bases matemáticas y físicas necesarias para comprender la Teoría de la Relatividad Especial, de una manera didáctica y para todo público, no sólo para personas entendidas en física avanzada.

Thank you Professor, your lecture is very interesting, and it is quite helpful to learn physics with a little history. I found that there are some mistakes in the subtitle, but it is not significant and I think I can understand it according to the context. Really impressive course, I hope I can see you in other courses.

The course was varied and motivating in its structure. Professor Larry Lagerstrom is an outstanding personality. It was a very enriching experience.

Excellent course. I feel I gained some insight into the core concepts of special relativity. I took to heart the "festina lente" ethos exposed early in the course by the instructor. Larry Lagerstrom is a fantastic teacher, he has the ability to explain often complex material in a way to that makes it understandable.

I thoroughly enjoyed the course and it was informative and we'll presented. I think I will miss listening about time. For me its been much therapeutic. It challenges my brain to even visualize these concepts and hence I can spend as much time studying it. The presenter knows his stuff and like his simplicity.

An outstanding course, it was what I was looking for to get a good understanding of the topic.

Really good course progression, well explained concepts. I am definitely happy and "1000%" satisfied with this amazing course, Professor Lagerstrom is simply amazing and he definitely deserves a strong acclamation!!

It was incredibly interesting and enjoyable experience,the course instructor was fabulous and i could understand many mind baffling information with a surprising ease.I am looking forward for stanford university's course on the general theory of relativity and i hope that it is taught by the same professor.

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.

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!

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!!

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.

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.

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.

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.

One of the best courses i have ever taken it uses simple everyday language,also it is great for those who want to take a quantitative approach to the whole concept of relativity.This course also features one of the best if not the best professor of physics that ever taught to me .

Larry is the best-I highly recommend! I loved this course and really enjoyed exploring these concepts. It is very well put together in a way that gives you time to ponder and try to truly understand the theory before getting to the "cool stuff." I will miss this weekly adventure!
