This review is from: A Most Incomprehensible Thing: Notes Towards a Very Gentle Introduction to the Mathematics of Relativity (Paperback)
Really amazing approaching to introducing a complicated subject with equations and not just the general idea. Sections on non-Euclidean geometry a reasonable explanation of the concepts. Better to include references to some of the proofs like the Bianchi identity. Good explanation of the energy momentum tensor and the sections on cosmology quite easy to follow.
Overall a great first step on the basic equations and differential geometry to stimulate further reading. Should include some cross references to some of the more difficult proofs.
Great to read alongside Daniel Flesich's book on vectors and tensors, especially on the connection coefficients and the curvature tensor.
