This course is very comprehensive and well prepared material for understanding the Special Theory of Relativity. Larry (the instructor) is very expert and has broad knowledge in explaining the course.

Hats off to the professor for being able to explain such mind-boggling concepts about the very nature of existence in an entertaining and intuitive way. One of my favorite courses on Coursera by far!

Amazing course, but the videos can be shorter as same concepts are explained more than once.

It is a very good course that is well organized and explained. The instructor was extremely great; he uses a lot of examples and thought experiments to help us imagine the situation. Although relativity is such a hard topic to learn for many people, the approach of instruction in this course makes it interesting and easy to be comprehended. After the course, you will find that you have learnt a great amount of knowledge about the topic and you can go into discussions about relativity related issues, even that you don't feel stressed during the course by the enormous amount of materials. Moreover, this course is suitable for anyone interested in the topic, even without much knowledge in physics before, because the course explains everything even the basic concepts.
I learnt A LOT from this course, and it encouraged me to love the topic, get excited about online learning and go even deeper in relativity study.

A brilliant course presented with knowledge and passion by Prof. Lagerstrom. It is very easy with minimal dependence on Mathematics. It certainly has inspired me to follow on to learn more about the Special and General theories. Thank you for providing the list of texts.

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/

The struggle to understand the marvellous structure of reality is an ennobling experience. The course is more engaging than a movie, I literally mean that. Professor Larry takes you on a roller coaster ride. I bet you would love the ride.
P.s. Don't be afraid of maths. Professor Larry has taken care of that part. It's only simple algebra.

Amazing，thanks very much for your professional and responsible in teaching.
I am always having the curiosity about Einstein,so i hope maybe someday you can give us the curriculum on his general theory of relativity.
Thanks again for all the courses i've learned from your teaching.

Excellent course! The instructor speaks slow, so I adjusted the speed to 1.25x. But that is his motto: Festina Lente. And to be honoust it is a very abstract course, so that some items were told two or three times, makes even the hardest parts understandable.

This fascinating course presented by a historian of science covers not just the basics of special relativity but the historical context as well. The lecturer starts off each week with some Einstein quotes and goes to great depths to explain the basic concepts at a level that is accessible to students with minimal experience of maths and physics. The concepts are firmly drilled in with plenty of optional quizzes after each mini-topic, and a summary video at the end of each week. The lectures are long but anyone short on time has the option to go straight to the weekly summary/quiz, and/or play videos at up to 2x speed (especially in weeks 2 and 3).
The main highlight for me was the explanation of the famous Twins Paradox and other related paradoxes which are resolved by understanding frames of reference and the relativity of simultaneity. Another bonus was an explanation of the bending of light by gravity through a simple thought experiment involving an accelerated elevator.
Some important topics not covered in the course, or only hinted at, are: treatment of accelerated reference frames (required to derive the relativistic rocket equations), relativistic momentum and kinetic energy (required to calculate the rocket fuel required) and relativistic energy (used to derive Einstein's mass-energy equivalence formula).
Overall I highly recommend the course to anyone with the time and inclination.

I never thought that studying Theory of Relativity could be so easy-All thanks to Larry for making the course so easy, conceptual at the same time interesting.
Looking forward for your course on General theory of Relativity.

This course was amazing, and I'm sad to see it go. It was interesting and full of new things that I have yet to learn and hopefully go more in-depth into during my university studies. I hope more people are informed about this course and I also hope that I still have access to the video lectures for future reference. Thank you for the experience!

Excellent course which presents the special theory of relativity in a very clear and accessible manner and also explains well the scientific, technological and biographical context of this discovery. I warmly recommend this course. Congratulations and thanks to Larry Lagerstrom

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.
