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!

The course was fantastic. I have struggled for years to understand the Special Theory of Relativity and I finally have a good grasp of the theory. The course is not difficult for anyone with at least a fundamental grasp of algebra and should be no problem with more math in their background. I would really like to see a course on the General Theory of Relativity taught by Professor Langerstrom. The lectures were clear and well documented and the short quizzes at the end of each subsection of the class materials really helped to make understanding the material presented easy to comprehend. I'd also love to see a book written by Dr. Langerstrom based on the course. I have a couple around home and they aren't as clear as the material presented in this course.

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, thank you. Just a suggestion for the movie with matter-antimatter fuel comparison to the center of the galaxy , when speaking of 38 kg antimatter, just for comparison perhaps we can convert this to truckloads of coal ... this way people will realize better how much energy it goes to producing 1 gram of antimatter, not even to mention 38 kg ... :")

Oddly, given subject matter, this is a very old school course - professor lecturing before a white board. Yet it works! I finally understand the Special Theory of Relativity and am convinced that time dilation and length contraction are real. Course is well paced. Outlines provided for taking notes for each session are very helpful. Quizzes and tests are appropriate. Highly recommend to anyone who has ever wondered if on might actually travel to another galaxy and return alive.

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

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.

It is a great course for anyone who wants not only to learn the theory but to understand it and how it's creator Albert Einstein came to these discoveries.

Very good, easy to follow course. Concepts like time slowing down and things becoming shorter at high velocities are no longer a mysterie to me after taking this course.
