It was wonderful experience to know the special theory of relativity from Larry, who has presented the course in very simple way to understand. Thanks a lot to Larry for providing such a good session.
Almost anyone can learn about the special theory of relativity from these lectures. I actually can't believe that I studied from a professor who teaches in the USA and in so simple way. I am grateful.

The course is a beautiful marriage of history, humanity, and science. The pace is slow at first but picks up steadily. I never thought I would ever understand special relativity but thanks to Professor Lagerstrom's thorough explanations, I am now comfortable with the concept and see the world in a different light. I wish Professor Lagerstrom will eventually produce a similar course on general relativity.

Dr Lagerstrom is a fantastic instructor and makes the most fearful physics seem ordinary. The course layout was perfect along with the pace. Also, Dr Lagerstrom made the concepts detailed with the right amount of math. I didnt believe I could understand Einstein without all the math. I enjoyed this opportunity to get a deeper understanding of one law of the universe and am eager to learn more.

Es el primer curso que encuentro con un nivel muy adecuado, va más allá de lo que siempre se dice sobre relatividad pero no es tan complejo como ser solo comprensible por especialistas o matemáticos.
It is the first course that I find with a very adequate level, it goes beyond what is always said about relativity but it is not so complex as to be only understandable by specialists or mathematicians.

Amazing introductory Course for Special Relativity. Might be a bit too basic at times w.r.t to maths but hey!, it never hurts to listen to things for a second time. Will definitely recommend to anyone looking to get into higher level physics. Being a High School student myself, I learned a lot and thoroughly enjoyed it. Thanks a lot to Stanford and Prof for making education freely available to all.

This course is engaging and interesting. The lecturer inspires you to learn and open your mind. The course itself can be hard in areas but if you stick with it, eventually you can work it out. There is a fair bit of algebra (which I never studied at school) but I still made it! I recommend this to anyone who wants to understand time and space and be drawn into the fantastic world of Einstein.

After reading almost a lifetime books about the works and accomplishments of Einstein (not being a graduated scientist but huge fan of the topic), it is amazing to follow this this course and explore this world in a whole new sight. Fantastic stuff brought by the best instructor by far. I think I will start all over again. A lot is much more obvious now, or is it? Triple A+ for Larry. Thank you.

I can't stress enough how good this course is. It's the best course i've ever taken in any subject. It's really impressive how much energy, thought, patience, care was put here. I'm deeply thankful for this. You guys made me so happy. Almost everything someone need to know about STR is here. And the teacher... maybe my favourite physics teacher ever. This guy is the golden standard of teaching.

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.
por Vijay S•
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.
por Helen C•
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.
por Ken H•
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!

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.
por RONALD D P•
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.
por Frank B•
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.

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.
por Sheshagiri K M R•
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!
por Om G•
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!
por Rusi R•
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 ... :")
por Amit M•
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.
por Catherine W•
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.
