Chapter VIII: Additional sources of reference

For those who want more information, the Internet offers a wide variety of documentary sources that can provide more data about the discoverers of non-Euclidean geometries as well as some of the conclusions come through these geometries are certainly (and unfortunately we are) not taught in any school of education (including, not even teach undergraduate mathematics career in a large number of universities).

Wikipedia is now becoming the largest source of an enormous amount of information both because it is an encyclopedia "online", accessible instantly, without having to pay for an expensive subscription use, and the fact that contributions are placed there from the world by people who knows what he is talking.
