Chimney

A chimney is a structure which provides ventilation for hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney, effect. The space inside a chimney is called a flue. Chimneys may be found in buildings, steam locomotives and ships. In the United States, the term smokestack (colloquially, stack) is also used when referring to locomotive chimneys or ship chimneys, and the term funnel can also be used.

The height of a chimney influences its ability to transfer flue gases to the external environment via stack effect. Additionally, the dispersion of pollutants at higher altitudes can reduce their impact on the immediate surroundings. In the case of chemically aggressive output, a sufficiently tall chimney can allow for partial or complete self-neutralization of airborne chemicals before they reach ground level. The dispersion of pollutants over a greater area can reduce their concentrations and facilitate compliance with regulatory limits.

Stack (geology)

A stack or seastack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. They are formed when part of a headland is eroded by hydraulic action, which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, forming free-standing stacks and even a small island. Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Stacks can provide important nesting locations for seabirds, and many are popular for rock climbing.

Isolated steep-sided, rocky oceanic islets, typically of volcanic origin, are also loosely called "stacks" or "volcanic stacks".

Formation

Stacks typically form in horizontally-bedded sedimentary or volcanic rocks, particularly on limestone cliffs. These rock types' medium hardness means medium resistance to abrasive and attritive erosion. A more resistant layer may form a capstone. (Cliffs with weaker rock—such as clay—tend to slump and erode too quickly to form stacks, while harder rocks such as granite erode in different ways.)

Landscape (band)

Landscape was an English Synthpop band, best known for the 1981 hits "Einstein A Go-Go" and "Norman Bates." Formed in London in 1974, the band toured constantly during the mid-to-late-1970s, playing rock, punk, and jazz venues and releasing two instrumental EPs on its own Event Horizon label. The group began experimenting with computer-programmed music and electronic drums in the late 1970s and early 1980s, making records in the emerging genre of synthpop.

Formation

Landscape was composed of Richard James Burgess (vocals, drums), Christopher Heaton (keyboards), Andy Pask (bass), Peter Thoms (trombone, keyboards), and John Walters (keyboards, woodwinds). The band built a following through live performances and touring before releasing their debut album Landscape in 1980. Their next album in 1981, From the Tea-Rooms of Mars...to the Hell-Holes of Uranus led to the Top Five U.K. hit "Einstein A-Go-Go." Their third album in 1982, Manhattan Boogie-Woogie was well received as a dance album. After release of this album, Heaton and Thoms left the band.

Landscape painting

Landscape painting, also known as landscape art, is the depiction in art of landscapes – natural scenery such as mountains, valleys, trees, rivers, and forests, especially where the main subject is a wide view – with its elements arranged into a coherent composition. In other works landscape backgrounds for figures can still form an important part of the work. Sky is almost always included in the view, and weather is often an element of the composition. Detailed landscapes as a distinct subject are not found in all artistic traditions, and develop when there is already a sophisticated tradition of representing other subjects. The two main traditions spring from Western painting and Chinese art, going back well over a thousand years in both cases. The recognition of a spiritual element in landscape art is present from its beginnings in East Asian art, drawing on Daoism and other philosophical traditions, but in the West only becomes explicit with Romanticism.

Landscape (horse)

Landscape (1813–1834) was a British Thoroughbred racehorse and broodmare who won the classic Oaks Stakes at Epsom Downs Racecourse in 1816. The filly's entire racing career consisted of one run in 1815 followed by three races in the space of thirteen days in June 1816. After winning the Oaks on her second racecourse appearance, she finished first and second in races at Ascot. Already pregnant at the time of her classic success, Landscape was retired from racing after Ascot and produced her first foal in the following spring.

Background

Landscape was a bay mare bred by her owner General John Leveson Gower who had won the Oaks with Maid of Orleans in 1809. Her sire, Rubens was a successful racehorse, who at the time of Landscape's conception was covering mares at Wheeler's Farm near Wokingham in Berkshire at a fee of 15 guineas. He sired two other classic winning fillies in Pastille, who won the 2000 Guineas and Oaks in 1816 and Whizgig, who won the 1000 Guineas in the same year. Rubens was champion sire in 1815, 1821 and 1822. Landscape's dam Housemaid (also known as Iris) produced several other good winners including Raphael, who finished second to Whisker in the 1815 Epsom Derby and Rainbow, who became a successful stallion in France.
