I want to study Einsteins General Theory of Relativity, but before i start reading about it can anyone of you recommend some good books about Curved Geometry? since i will need it to understand the first part.
What are some good books for learning general relativity?
I have studied some of Einstein's Theory of General Relativity, and I understand that it states that gravity isn't a force but rather the effects of objects curving space-time. If this is true, then why are we instructed in middle school that it is a force?
