+Gaussian curvature measures the intrinsic bending of a surface at a point, revealing how much it deviates from a flat plane without reference to external space. It is the product of the two [principal curvatures](/wiki/principal_curvature) and, by Gauss's remarkable [Theorema Egregium](/wiki/theorema_egregium), can be determined purely from measurements within the surface itself. This fundamental property makes it a cornerstone of surface analysis in mathematics.
