A first course in general relativity Book

Usually, physics/ math textbooks give me giant yawns, but this one is definitely exceptional, I enjoyed reading it a lot. thank god Bernard Schutz skips all that torturous index gymnastics of differential geometry and jumps straight into special and general relativity (where half of the quantities in diff geom happily die and leave us in peace). his introduction to tensor calculus is very helpful. lots of clear explanations, for example why mutual length contraction or time dilation is not a contradiction at all (this one has ALWAYS got me), or how Einstein followed his particular line of reasoning find analogy of Newton's gravity- no preferred coordinate system- local conservation of energy- special relativity in the locally inertial frame to develop the field equation. gets a bit more technical when it comes to black holes and neutron stars, but bearable. fascinating book!
