http://web.mit.edu/hyperbook/Patrikalakis-Maekawa-Cho/node186.html In Tractatus de configurationibus qualitatum et motuum, the 14th-century philosopher and mathematician Nicole Oresme introduces the concept of curvature as a measure of departure from straightness; for circles he has the curvature as being inversely proportional to the radius; and he attempts to extend this idea to other curves as a continuously varying magnitude. The curvature of a differentiable curve was originally defined through osculating circles. In this set…

NettetSmooth surfaces, umbilics, lines of curvatures... 5 1.3 Paper overview In section 2, the Monge form of a surface is recalled. Second order properties —umbilics and lines of curvature— are presented in section 3. The classification of contact points between the surface and spheres is presented in section 4.
