Tensor analysis is backbone of General theory of relativity... But it is a difficult mathematical concept. How can i know more about tensor analysis not in just a pure mathematical way?
General relativity and Quantum theory are two pillars of physics... The unified theory concept trying to combine 4 basic forces of nature. I don't know what is the actual conflict between gravitational force and other 3 forces?
Hi I couldn't go through all posts but this is what I feel Real Newton vs Einstein,
