Among the several different types of this mathematical property that are defined for surfaces are the normal and principal types. The Gaussian variety can indicate whether a tangent plane touches the surface or cuts through it. FTP, give the term that also corresponds to the property of 4-dimensional spacetime that Einstein used to account for gravity in his theory of general relativity.
