Ohanian writes with a distinct voice that prioritizes over mathematical abstraction. While many GR texts start with the heavy machinery of differential geometry (manifolds, tensors, differential forms) before touching physics, Ohanian introduces mathematical tools only as they are needed to solve physical problems.
