I find this course to be very confusing. It is too rushed and confusing. I've already completed similar course with Stanford University and intended to use this to consolidate my learning. Sadly, however, it has produced the opposite effect and I am now confused, where before I was clear. I'm thinking of unsubscribing.

The lecturer is obviously knowledgable but he does not sufficiently explain assigned variables and expound on the concepts so a begineer with no background can understand them. It appears he assumes that the student already has some experience with these concepts. Language at time also makes it difficult has his use on the english langauge vocabulary is at a basic level, making certain points confusing. He also moves too quickly on the equations for a begineer to keep up unless the begineer has prior knowledge.

It was a great experience,it was my first online course its help me in understandin physics principle in more details and help in my degree course

Good , but there are "high jumps" from start equations to final equations.

Some explanations are -to me- confuses, week 4 and 5

The online course "Understanding Modern Physics: Relativity and Cosmology" is an excellent resource for anyone interested in delving into the fascinating world of modern physics. The course provides a comprehensive overview of the fundamental concepts of relativity and cosmology, offering a detailed exploration of topics such as the theory of special relativity, the theory of general relativity, and the Big Bang theory. The content is presented in a clear and concise manner, making it accessible to both beginners and those with some background in physics. The course also includes interactive exercises and quizzes to reinforce learning, ensuring that students can grasp the material effectively. Overall, "Understanding Modern Physics: Relativity and Cosmology" is a highly informative and engaging online course that is sure to deepen your understanding of the intriguing field of modern physics.

I learned a lot from this basic introduction to Relativity and Cosmology. Prof. Wang gives very inspiring lectures with the right emphasis on key principles that help explain many non-intuitive aspects of these to concepts in modern physics. I am so inspired to continue with Prof. Wang's other courses on Coursera.

Thanks

Yi Wang does an excellent job of capturing the most important elements of the subject and demonstrating how they can be best understood. Well done!

Very interactive. The quizzes and assignments make you reflect and think deepera bout the material.

Some words are incomprehensible and is different from the captions. Also, please add more examples.

Learning from this course on modern physics was a great experience. The course was very interesting and motivating. It provided a lot of important information and content on modern physics. I feel very lucky that I learned from this course. The instructor of this course Yi Wang is an amazing teacher who made the course content very interesting and easy to learn.

Hello everyone, my name is Khusan Alibekov. I liked this course. In my view, this course is very well-constructed and designed course. I would like to study about more this thing and I want to new course about these things

Soy ingeniero de Caminos Canales y Puertos de España. Tengo 78 años por lo que me ha costado mucho el estudio de este curso, pero me ha gustado mucho. ¡¡¡ Seguiré con el siguiente!!!. El profesor de 10 . Muchas gracias

Were didactical and filled with interesting mid-video questions that make you reflect and really understand the theory being explained. Clearly a very experienced and respectable professor. Thanks Mr. Wang

Es un curso muy avanzado en terminos de conocer y tener buenos fundamentos de fisica moderna y Calculo.

Ayudaria para el habla hispana una mejor traduccion del español.

Por lo demas excelente.

This was a most interesting course. It clarified many points for me which I had picked up from previous readings..

The quality of the lectures was excellent.

Professor Wang not only explained the content but also the reasons behind relativity and cosmology. I gained a more intuitive understanding.

Instructor did an excellent job of introducing new topics by asking rhetorical questions that highlight what is to be covered next.

It was undoubtedly a great experience that have enhansed me a lot and provided we with great knowledge

Good course online , very understanding and fiurthered my knowledge

Very interesting and helpful to understand top of the physics!
