The book explains why a lot of important mathematical concepts such as Gaussian curvature and Riemannian manifolds manifest themselves in general relativity. A lot of the things we take for granted just do not hold true in the world of black holes. I particularly liked the description of how chaos arises from small perturbations in initial conditions and how this manifests itself in terms of the overall motions of planetary bodies and the dynamics of systems. Furthermore, it is notable how astronomers used the deviation from what they expected as a way of finding Neptune and eventually Pluto, although the latter in a sense was a mistaken find.

Overall, this was an interesting read and put a lot of mathematics into perspective. I enjoyed it very much and would highly recommend it.
