Artist's Impression
An artist's impression, artist's conception, artist's interpretation, or artist's rendition is the representation of an object or a scene created by an artist when no other accurate representation is available. It could be an image, a sound, a video or a model. Artist's impressions are often created to represent concepts and objects that cannot be seen by the naked eye; that are very big, very small, in the past, in the future, fictional, or otherwise abstract. For example, in architecture, artists' impressions are used to showcase the design of planned buildings and associated landscape. Artists' impressions are particularly prominent in space art. Artist's depictions of prehistoric life are known as paleoart. See also *Architectural rendering *Concept art Concept art is a form of visual art used to convey an idea for use in film, video games, animation, comic books, television shows, or other media before it is put into the final product. The term was used by the Walt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobias Mayer
Tobias Mayer (17 February 172320 February 1762) was a German astronomer famous for his studies of the Moon. He was born at Marbach, in Württemberg, and brought up at Esslingen in poor circumstances. A self-taught mathematician, he earned a living by teaching mathematics while still a youth. He had already published two original geometrical works when, in 1746, he entered J. B. Homann's cartographic establishment at Nuremberg. Here he introduced many improvements in mapmaking, and gained a scientific reputation which led (in 1751) to his election to the chair of economy and mathematics at the University of Göttingen. In 1754 he became superintendent of the observatory, where he worked until his death in 1762. He has been credited with developing an early form of regression analysis in 1750, though 50 years earlier Isaac Newton had used similar methods. Career Mayer's first important astronomical work was a careful investigation of the libration of the Moon (''Kosmographisc ...

Province Of Pennsylvania
The Province of Pennsylvania, also known as the Pennsylvania Colony, was a British North American colony founded by William Penn, who received the land through a grant from Charles II of England in 1681. The name Pennsylvania was derived from Latin, meaning "Penn's Woods", a reference to William Penn's father Admiral Sir William Penn. History European settlement The Province of Pennsylvania was one of two major Restoration colonies in colonial-era British America. A plan for government of the colony of Pennsylvania was heavily influenced by the ideas and utopian aspirations of English political scientist James Harrington. The proprietary colony's charter remained in the Penn family until the Penns were ousted in 1776 during the American Revolutionary War, and the Commonwealth of Pennsylvania was established as one of the original thirteen states. In June 1776, the Lower counties on the Delaware, a separate colony within the Province of Pennsylvania, broke away from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Plan Of The West Line Or Parallel Of Latitude - WDL
A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is '' a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, '' a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest known ancestor of A is ''aleph''—the first letter of the Phoenician ...

Cape Of Good Hope
The Cape of Good Hope ( ) is a rocky headland on the Atlantic Ocean, Atlantic coast of the Cape Peninsula in South Africa. A List of common misconceptions#Geography, common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic Ocean, Atlantic and Indian Ocean, Indian oceans. In fact, the southernmost point of Africa is Cape Agulhas about to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about east of the Cape of Good Hope). When following the western side of the African coastline from the equator, however, the Cape of Good Hope marks the point where a ship begins to travel more eastward than southward. Thus, the first modern rounding of the cape in 1487 by Portuguese discoveries, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Man-of-war
In Royal Navy jargon, a man-of-war (also man-o'-war, or simply man) was a powerful warship or frigate of the 16th to the 19th century, that was frequently used in Europe. Although the term never acquired a specific meaning, it was usually reserved for a sailing ship armed with cannon. The rating system of the Royal Navy classified men-of-war into six "rates", a "first-rate" having the greatest armament, and a "sixth-rate" the least. Description The man-of-war was developed in Portugal in the early 15th century from earlier roundships with the addition of a second mast to form the carrack. The 16th century saw the carrack evolve into the galleon and then the ship of the line A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactics in the Age of Sail, naval tactic known as the line of battl .... The evolution of the term has been given thus: Th ...

Cockfield, County Durham
Cockfield is a village on the edge of Teesdale, County Durham, England. It is situated 8 miles to the south-west of Bishop Auckland, north-west of Darlington and south-west of Newcastle upon Tyne. Remains found on Cockfield Fell suggest there was a settlement in the area during the Iron Age. The parish church, dedicated to St Mary the Virgin, probably dates from the late 12th century. Coal mining began in the area in the medieval period. When the South West Durham coalfield was opened in the 19th and 20th centuries the population of the village grew significantly.

Transit Of Venus
A transit of Venus takes place when Venus passes directly between the Sun and the Earth (or any other superior planet), becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus is visible as a small black circle moving across the face of the Sun. Transits of Venus reoccur periodically. A pair of transits takes place eight years apart in December (Gregorian calendar) followed by a gap of 121.5 years, before another pair occurs eight years apart in June, followed by another gap, of 105.5 years. The dates advance by about two days per 243-year cycle. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities. The last pairs of transits occurred on 8 June 2004 and 5–6 June 2012. The next pair of transits will occur on 10–11 December 2117 and 8 December 2125. Transits of Venus were in the past used to determine the size of the Solar System. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
