Architect Richard Buckminster Fuller (1895-1983) invented various geometric structures based on triangles, called geodesic domes. In complete closed form as a polyhedron they are sometimes called "bucky balls". In 1990 chemists succeeded in making useful quantities of molecules in which 60 carbon atoms are arranged in such a structure. They are called "fullerenes", "buckminsterfullerenes" or "compound C60". See "Buckyball" Molecule - Hype or Hope?
