A **cubic surface** is a projective variety studied in algebraic geometry. It is an algebraic surface in three-dimensional projective space defined by a single quaternary cubic polynomial which is homogeneous of degree 3 (hence, cubic). Cubic surfaces are del Pezzo surfaces.

### Famous quotes containing the words surface and/or cubic:

“Brave men are all vertebrates; they have their softness on the *surface* and their toughness in the middle.”

—Gilbert Keith Chesterton (1874–1936)

“One of the great natural phenomena is the way in which a tube of toothpaste suddenly empties itself when it hears that you are planning a trip, so that when you come to pack it is just a twisted shell of its former self, with not even a *cubic* millimeter left to be squeezed out.”

—Robert Benchley (1889–1945)
