Ruled Surfaces in Architecture
Doubly ruled surfaces are the inspiration for curved hyperboloid structures that can be built with a latticework of straight elements, namely:
- Hyperbolic paraboloids, such as saddle roofs.
- Hyperboloids of one sheet, such as cooling towers and some trash bins.

Famous quotes containing the words ruled, surfaces and/or architecture:
“Rare is the virtue that’s not ruled by Fortune,
That stands unshaken even when Fortune flees.”
—Ovid (Publius Ovidius Naso)
“But ice-crunching and loud gum-chewing, together with drumming on tables, and whistling the same tune seventy times in succession, because they indicate an indifference on the part of the perpetrator to the rest of the world in general, are not only registered on the delicate surfaces of the brain but eat little holes in it until it finally collapses or blows up.”
—Robert Benchley (1889–1945)
“Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
—Ralph Waldo Emerson (1803–1882)
