Nice book for undergraduates and very up to date in many aspects. Schwarzschild is nicely developed for a bachelor level in Sciences.<br>I would recommend this as the first book on the subject, followed by Carroll’s notes, McMahon, MTW, Lightman-0Price-Teukolsky..., Wald and Hawking and Ellis, in this order.<br>Thorne and Blandford at hand for the development of the physics underlaying the energy momentum tensor as well as the compiled info for the state of the art in experimental on Gravitation.
