Thanks for helping me understand the Special Theory of Relativity, covered a lot of ground but repeated it so it really could sink in. Like your style and want to thank you for your assistance. Thanks

This is an excellent course for everyone who is interested in Einstein's special theory of relativity. All concepts about the theory are presented in a simple and intuitive way, therefore anyone with basic math knowledge will understand it easily.
Also, professor Larry Lagerstrom is a very charismatics person, and his talent for teaching other people made this course an amazing experience.

This is a greate course. Many thanks to all involved in providing such a very well elaborated course, modeling such a complex subject in a "simplified" version that is reachable by many people that would be disencouraged by maths and formulas intrinsic to the subject. Thanks also to Professor LArry by making the course even more entusiastic and attractive by given many examples along it.

I really loved this course. I reached my goal of (at least believing myself :-) that I now have a basic understanding of the special theory of relativity, even quantitatively at some level. Required level of math proved to be rather limited, and for me not a problem at all. Really enjoyed whatching the videos because of the relaxed way in which they are presented by the professor!

The course is very well designed for someone with little or no knowledge of the subject matter. The only quibble I had was with respect to the time spent on the very basics of the maths and what I felt was somewhat repetitive nature of some of the points made, if adjusted for that one could lop off several hours from the course length and might actually encourage more participation.

This is the first course I ever finished on coursera! Thanks to Prof. Lagerstrom for making the course so easy and engaging for people with any level of maths and physics knowledge to follow and pick up. I've really enjoyed the whole journey and gained knowledge about this universe. It's definitely worth recommending to anyone who's interested to know more about the world around us.

Great course. The instructor goes slow and repeats important points for maximum retention. Key equations are rigorously derived (requiring only high school algebra) but are rarely required in the weekly quizzes. After completing this course I have a better understanding of special relativity and (thanks to the final week) better understand its relationship to general relativity.

Fascinating course and a material presented in a super approachable way. Many paradoxes thoroughly explained - for the first time for me everything from start to finish was crystal clear. Amazing how almost all of these interesting phenomena, including Lorentz transformation, can be derived simply by using pythagorean theorem and common sense. Can I have a second helping please!

Excellent course. Well-designed and very well presened. Developed for amateur astronomers like me who want the frame of information,without going to university. Prof is excellent! Excellent lecturer, beautiful sense of humor and very descriptive. He issued a lot of effort in preparing and presenting the course, which is top quality.
Thank you for everything.

I have always wanted to understand the basics of the Special Theory of Relativity but when trying to read about it found that I did not have the appropriate post high school background in math and physics to understand the theory. Professor Lagerstrom presented the information in a cogent manner that enabled me to grasp both the theory's underlying principles and its beauty.

Very well done. I learned a lot and I'm very pleased with the results I achieved. I learned to study with purpose and to be patient in my learning. I learned to listen intently and apply what I learned. Even old dogs can learn new tricks. I really enjoyed listening to Mr Lagerstrom's lectures. He is knowledgeable and interesting to listen to. He made the course easy to follow.

This course is outstanding. I have tried other self-learning STofR courses and never got past the preliminary steps. The professor is outstanding, the amount of effort to make Special Relativity concepts understandable at the high school algebra level must have been immense. Thanks for expending the effort.

Es un gran curso, el profesor tiene una gran experiencia haciendo clases y he aprendido mucho tomando el curso, ayuda que esté el texto en ingles de sus diálogos para traducirlo si hay alguna duda. El curso cumplió todas mis expectativas, felicito al equipo que diagramó y preparó este lindo curso para los amantes de la física y la astronomía. Un abrazo a todo el equipo.

just amazing, got no words to describe how beautifully this course was taught. Anone with having little to no physics background can learn from this course. The way Larry Randeles taught , made me understand each concepts deep into my bones.In the end , i just want to express my gratitude towards Larry , thank u larry for making this course understandable for anyone.

This is a wonderful path to embark on for those who wish to have a different perspective on the natural laws. It provides a robust platform for pursing more advanced journeys and enhance their ability to analyse and contemplate. The course material is really good and is definitely recommended for people who wish to step out of their boundaries and grasp more of life.

For foreigners, the subtitles are very useful. Sometimes they are not correct and students could have correct them if there would be some tool to propose corrections as it is sometimes the case for the correction of OCR for old newspaper.
I have learned a lot with this course and would like to thank you for providing this material to all the students in the world.

I must say that it is a great course. It moves along nicely (though at times a bit fast); the context has been laid out well and there is enough of summarizing and 'looking back' before moving forward. This course is an ideal beginning for anyone who wants to deep dive into relativity at a later stage! My thanks to Coursera and special thanks to Prof. Lagerstrom!

As a student hoping to study Physics in University, this course offered a fantastic and simple to follow explanation for concepts that are often portrayed as impossible to understand by mainstream media. Props to Professor Lagerstrom and the rest of the team in developing a course that even a person with a passing interest in physics can follow comprehensively!

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 ... :")

A well-paced introduction to theory of relativity. The instructor offers a historical angle to the developments, an especially useful perspective for students, beyond the intuition-bending clutter of mathematical derivations. I highly recommend this over other courses on this subject to students of all disciplines, especially those of engineering disciplines.

The professor is a joy to listen to and wish he had more courses on here. While I couldn't follow a couple of times, the benefits of taking a course that goes far beyond our daily experiences is astronomical. I would absolutely recommend this to anyone with even the slightest interest in engaging a more hands on approach to the Special Theory or Relativity.

A complex and challenging topic was presented with great clarity. Some of the early lectures seemed rather slow and laboured, especially if one has some scientific or mathematical training, but getting a clear understanding of the 'basic' topics allowed the more challenging aspects of the course to be cleary understood. Thank you for an excellent course.

An excellent introduction to a fascinating subject. Each individual lecture is short and focused so the amount of new material introduced can always be understood and absorbed by an engaged student. Once key concepts are introduced, they are regularly reinforced in subsequent lectures. Highly recommended for anyone interested in exploring this subject.

This was an excellent course which covered the material extremely well and expalined all the concepts clearly. The maths is simple but sound and easy to understand. The Instructer taught this course like a thriller, after every lecture . .I would say to my self . .just 1 more and then I will take a break, and then it ended and I was sad, it was over.

The introduction on how to follow the course is crucial in the successful understanding of Einstein's Theory. I thought how Einstein came out with theory of relativity was beyond my ability to comprehend. But the the step by step approach by by Dr Lagerstrom makes the whole theory simple to understand. Thank you very much. I really enjoy this course.
