I recommend everyone with even the slightest interest in the world or the need to understand things like time zones, seasons, flight paths etc. to get a globe, even just a small one. You just can't understand a non-Euclidean space by looking at projections and 3D globes on screens don't seem to cut it either.

In fact, manifolds[0] are defined in terms of local coordinate charts. :-) [0]: https://en.m.wikipedia.org/wiki/Manifold https://en.m.wikipedia.org/wiki/Manifold
