| Textbook | Comparison to Ohanian | | :--- | :--- | | MTW (Misner, Thorne, Wheeler) | MTW is the bible of GR, but it is massive and overwhelming. Ohanian covers similar ground but is much more concise and organized linearly (Chapter 1 -> 2 -> 3), whereas MTW is non-linear. | | Bernard Schutz ("A First Course") | Schutz is gentler and better for self-study by beginners. Ohanian assumes a higher level of mathematical maturity and moves faster toward rigorous derivations. | | Sean Carroll ("Spacetime and Geometry") | Carroll focuses heavily on the modern differential geometry approach (Manifolds, Forms). Ohanian is more grounded in the traditional "Physics" style of argument. | | Steven Weinberg ("Gravitation and Cosmology") | Weinberg is famously rigorous and difficult. Ohanian is essentially a more accessible, pedagogically refined version of Weinberg's approach. |
The book does not begin with tensors. It begins with a paradox: the instantaneous action of Newton’s gravity versus the finite speed of light. Ohanian walks the reader through the equivalence principle using thought experiments involving elevators, rockets, and light beams. This section is lauded for its clarity in explaining why time must slow down in a gravitational field. ohanian gravitation and spacetime pdf
