The History of Non-Euclidean Geometry - A Most Terrible Possibility - Extra History - #4

In the early 19th century, people started to wonder if the Fifth Postulate couldn't be proven at all--meaning that it could be right, but it could also be wrong. Bolyai, Lobachevsky, and Riemann started exploring hyperbolic geometry and other strange realms... Support us on Patreon! http:/
