Thank you to Dr. Randles for teaching us this excellent course, for preparing all the lessons in a simple manner, he makes us see the theory easy. And thank you for teaching us not only the scientist, but also the human person through Einstein quotes.

Try to become not a person of success, but try rather to become a person of value

great course. clear lectures which elucidate the concepts.

Excellent introduction to the Special Theory of Relativity: steady pace, lucid explanations and thorough comprehension.

This course provides a clear and accessible introduction to a theory that can otherwise be difficult to grasp.

Fully Packed with knowledge !!. Best Course for First year students in physics and general people who are interested in physics and with no background in math.

This course has been very enriching in terms of personal knowledge, thank you! My goal was to learn, regardless of its practical usefulness

Superb teaching.

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/

A enjoyable and well laid out course, mathematics level: high school, some rigorous algebraic proofs though not essential to pass.

Very well paced, with very clear explanations and interesting insights.

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.

Amazing . time is suspect

i love this

Exceptional

This course is really brilliant, Professor Lagerstrom ( I hope I have spelt the name correctly ) really knows the subject, a superb lecturer.

This course was truly an excellent way to learn about Einstein's Special Theory of Relativity. The content covered most of the main aspects of Special Relativity, and the instructor did a top notch job of explaining how the various aspects of the theory are derived and many implications of the Theory. The maths involved in this course is no more than high-school level algebra with a few tricks, and as such the course should be within most people's reach with a bit of effort. Mind you, the concepts themselves are somewhat counter-intuitive, so be prepared to think a lot about the implications. However, all that being said, I highly recommend this course! It is a very well presented and accessible way to start to grasp Einstein's most profound work in his "miracle year" of 1905.

A great exercise in thinking.

Simple, objective, informative. Amazing course, thanks Coursera !

Brilliant. Fantastic teacher. And I'm not good at maths at all but I came away with quite a respectable understanding of the underlying notions of Special Relativity which is exactly what I was looking for.

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.

Very interesting, very well explained.

Top, easy to understand

100% recommend for anyone who enjoys the fun implications of higher-level math!

Excellent course. Prof. Lagerstrom provided detailed explanation regarding the special theory of relativity in a very simple and understanding manner. I hope to attend more courses from the good professor soon. Thank you for sharing your knowledge to us, sir. Kudos.

Very well put together course, recommended to everyone who want to understand the basic relativistic concepts. Thank you professor L. R. Lagerstrom for doing such a wonderful job.
