For beginners studying General Relativity (GR), Hartle's book is recommended as it presents physics concepts before introducing tensors, making it accessible for those with a solid foundation in calculus. It's essential to have a good understanding of Special Relativity (SR) before diving into GR. Other notable texts include Schutz and Ohanian for advanced undergraduates, Carroll and Misner, Thorne, and Wheeler (MTW) for senior or first-year graduate students, and Wald as a comprehensive graduate-level text. Most GR textbooks introduce necessary mathematical concepts, including tensor calculus, throughout the material. For those interested in cosmology, Cheng's book is a shorter alternative to Hartle, though it lacks detailed coverage of black holes. When choosing between Dirac's and Schutz's texts, Schutz is advised as Dirac's work is not suited for beginners. Engaging with exercises is crucial for effective learning in this field.
