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.

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

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

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.

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

Very interesting and helpful to understand top of the physics!

A very interesting course.

e​xcellent

Intriguing

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.
