Hyperbolic geometry

Hyperbolic geometry (geometry of Lobachevsky) is the non-Euclidean geometry in which the parallel postulate is replaced. In David Hilbert's 1900 lecture before the International Congress of Mathematicians, he states that "We may therefore say that [hyperbolic geometry] is a geometry standing next to euclidean geometry."
