Course Overview: https://youtu.be/xyF-MmGNxd0 The 20th century was known as the century of physics. In the past 120 years, concepts such as space, time, energy, entropy and particles were understood to much deeper levels. New paradigms of thinking such as relativity and quantum mechanics emerged. This course is the first course in the Understanding Modern Physics series, which covers an introduction to special relativity, general relativity and cosmology. We will find: (i) How space and time are relative to observers, and unified into a more fundamental construction of spacetime; (ii) Why the spacetime is not absolute, but rather curves in response to matter, and how gravity emerge as a result of such spacetime curvature; and (iii) What is the framework to understand the evolution of the whole universe, and how that is related to problems such as the origin of space and matter, and the fate of our universe. Who this is for: Physics students and science enthusiasts looking to advance their theoretical knowledge. Note: the videos with a (*) are optional. They provide complementary information but not in the learning objective or assignment questions. Feel free to choose to watch them or not.

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

Instructor did an excellent job of introducing new topics by asking rhetorical questions that highlight what is to be covered next.
SH
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!
SJ
It's an excellent introduction to the topics mentioned. The Special Relativity part is explained pretty well.
VD
course is great and quality of material is also good, yi wang - great professor, but i found it a bit difficult to get through his examples but that was my individual experience else, its good...
JB
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.
AS
Good course online , very understanding and fiurthered my knowledge
NA
We can develop a deeper insight in to the theory of Relativity.
DP
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
SA
everything you need to know about modern physics. start here
YR
It was undoubtedly a great experience that have enhansed me a lot and provided we with great knowledge
AG
Really fun and taught me so much 10/10 you will enjoy.

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

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.
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.

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.
