Description
In Italy we invented pizza, gelato, among other things like perspective, complex numbers, non . Yes, Italy is not only fashion, design and awesome cars but also a land of great mathematicians. In particular, Non-Euclidean geometry was first discovered by Saccheri but it was so an amazing discovery at that time that nobody believed it make sense, even its creator. We were not ready yet.
Something like two hundred years later Eugenio Beltrami discovered the Pseudosphere and it was like saying to the world:
Hey, here it is a surface with negative curvature, it exists and it is real. It makes sense!
Consider that the Fifth postulate was more than two thousands years old, and that it is assumed as true by the human kind.
So a big step forward in geometry was the introduction of an hyperbolic plane model, first with the Beltrami model, than the beautiful Poincaré disk.
