Indeed, Catalanproved in 1842 that the helicoid and the plane were the only ruled minimal surfaces. [1] See more The helicoid, also known as helical surface, after the plane and the catenoid, is the third minimal surface to be known. See more It was described by Euler in 1774 and by Jean Baptiste Meusnier in 1776. Its name derives from its similarity to the helix: for every See more • Generalized helicoid • Dini's surface • Right conoid See more • "Helicoid", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • WebGL-based Interactive 3D Helicoid See more The helicoid and the catenoid are locally isometric surfaces; see Catenoid#Helicoid transformation.
