Smart glass is the name given to a class of materials and devices that can be switched between a transparent state and a state which is opaque, translucent, reflective, or retro-reflective. The switching is done by applying a voltage to the material, or by performing some simple mechanical operation. Windows, skylights, etc., that are made of smart glass can be used to adjust indoor lighting, compensating for changes of the brightness of the light outdoors and of the required brightness indoors.

Famous quotes containing the words smart and/or glass:
“The majority of persons choose their wives with as little prudence as they eat. They see a trull with nothing else to recommend her but a pair of thighs and choice hunkers, and so smart to void their seed that they marry her at once. They imagine they can live in marvelous contentment with handsome feet and ambrosial buttocks. Most men are accredited fools shortly after they leave the womb.”
—Edward Dahlberg (1900–1977)
“Thales claimed that everything was water. He also put wine into water to sterilize it. Did he really believe he was putting water into water to sterilize it? Parmenides, like most Greeks, knew that wine was not water. But while lifting a glass of wine to his lips, he denied that motion was possible. Did he really believe that the glass was not moving when he lifted it?”
—Avrum Stroll (b. 1921)
