Cloud

In meteorology, a cloud is an aerosol comprising a visible mass of liquid droplets or frozen crystals made of water or various chemicals. The droplets or particles are suspended in the atmosphere above the surface of a planetary body. On Earth clouds are formed by the saturation of air in the homosphere when air cools or gains water vapor.

Cloud types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin names due to the universal adaptation of Luke Howard's nomenclature. It was formally proposed in December 1802 and published for the first time the following year. It became the basis of a modern international system that classifies these tropospheric aerosols into several physical forms which can be found at various altitude levels or étages.

Andy Warhol

Andy Warhol (/ˈwɔːrhɒl/; born Andrew Warhola; August 6, 1928 – February 22, 1987) was an American artist who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertisement that flourished by the 1960s. After a successful career as a commercial illustrator, Warhol became a renowned and sometimes controversial artist. The Andy Warhol Museum in his native city, Pittsburgh, Pennsylvania, holds an extensive permanent collection of art and archives. It is the largest museum in the United States dedicated to a single artist.

Warhol's art used many types of media, including hand drawing, painting, printmaking, photography, silk screening, sculpture, film, and music. He was also a pioneer in computer-generated art using Amiga computers that were introduced in 1984, two years before his death. He founded Interview magazine and was the author of numerous books, including The Philosophy of Andy Warhol and Popism: The Warhol Sixties. He managed and produced The Velvet Underground, a rock band which had a strong influence on the evolution of punk rock music. He is also notable as a gay man who lived openly as such before the gay liberation movement. His studio, The Factory, was a well known gathering place that brought together distinguished intellectuals, drag queens, playwrights, Bohemian street people, Hollywood celebrities, and wealthy patrons.
