However, there is a cult classic that sits comfortably between the rigorous mathematics of Wald and the conversational tone of Schutz. That book is . ohanian gravitation and spacetime pdf
However, while the PDF is convenient, consider supporting the authors. The print edition is a masterpiece of science communication. If you are a student on a budget, use your university’s interlibrary loan or purchase a used older edition (the 1st or 2nd edition are still fundamentally correct for classical GR). | Textbook | Difficulty | Math Level |
Find a legitimate copy—physical or digital—and work through it patiently. The path to understanding Einstein is long, but Ohanian is one of the best guides you will find.

Introduction: The Search for the Right Textbook
Ultimately, Ohanian’s Gravitation and Spacetime will not make you a string theorist overnight, but it will give you the strongest possible foundation in how mass tells space how to curve, and how space tells mass how to move.
