# Surfaces

A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space.A surface of revolution is a surface in Euclidean space created by rotating a curve (the generatrix) around an axis of rotation.Examples of surfaces of revolution generated by a straight line are cylindrical and conical surfaces depending on whether or not the line is parallel to the axis.In mathematics, surfaces of class VII are non-algebraic complex surfaces studied by (Kodaira 1964, 1968) that have Kodaira dimension −∞ and first Betti number 1. Minimal surfaces of class VII (those withIn algebraic geometry, a surface of general type is an algebraic surface with Kodaira dimension 2. Because of Chow’s theorem any compact complex manifold of dimension 2 and with Kodaira dimension 2 will actually be an algebraic surface, and in some sense most surfaces are in this class.Surfaces of a Broken Marching Band is Ezekiel Honig’s fifth album, released October 27, 2008 by Anticipate Recordings.Surface-supplied diving is diving using equipment supplied with breathing gas using a diver’s umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell.Surface supplied diving skills are the skills and procedures required for the safe operation and use of surface-supplied diving equipment.
