As The Crow Flies
__NOTOC__ The expression ''as the crow flies'' is an idiom for the most direct path between two points, rather similar to "in a beeline". This meaning is attested from the early 19th century, and appeared in Charles Dickens's 1838 novel ''Oliver Twist'': Crows do conspicuously fly alone across open country, but neither crows nor bees (as in "beeline") fly in particularly straight lines.Villazon, Luis.“Do crows actually fly in a straight line?” BBC Focus (August 30, 2017). While crows do not swoop in the air like swallows or starlings, they often circle above their nests. One suggested origin of the term is that before modern navigational methods were introduced, cages of crows were kept upon ships and a bird would be released from the crow's nest when required to assist navigation, in the hope that it would fly directly towards land. However, the earliest recorded uses of the term are not nautical in nature, and the crow's nest of a ship is thought to derive from its shap ...

Crow In Flight
A crow is a bird of the genus ''Corvus'', or more broadly a synonym for all of ''Corvus''. Crows are generally black in colour. The word "crow" is used as part of the common name of many species. The related term " raven" is not pinned scientifically to any certain trait, but is rather a general grouping for larger ''Corvus spp.'' Species * ''Corvus albus'' – pied crow (Central African coasts to southern Africa) * ''Corvus bennetti'' – little crow (Australia) * ''Corvus brachyrhynchos'' – American crow (United States, southern Canada, northern Mexico) * ''Corvus capensis'' – Cape crow or Cape rook (Eastern and southern Africa) * ''Corvus cornix'' – hooded crow (Northern and Eastern Europe and Northern Africa and Middle East) * ''Corvus corone'' – carrion crow (Europe and eastern Asia) *''Corvus culminatus'' – Indian jungle crow (South Asia) * ''Corvus edithae'' – Somali crow or dwarf raven (eastern Africa) * ''Corvus enca'' – slender-billed crow (Malaysia, ...

Idiom
An idiom is a phrase or expression that typically presents a figurative, non-literal meaning attached to the phrase; but some phrases become figurative idioms while retaining the literal meaning of the phrase. Categorized as formulaic language, an idiom's figurative meaning is different from the literal meaning. Idioms occur frequently in all languages; in English alone there are an estimated twenty-five million idiomatic expressions. Derivations Many idiomatic expressions were meant literally in their original use, but sometimes the attribution of the literal meaning changed and the phrase itself grew away from its original roots—typically leading to a folk etymology. For instance, the phrase "spill the beans" (meaning to reveal a secret) is first attested in 1919, but has been said to originate from an ancient method of voting by depositing beans in jars, which could be spilled, prematurely revealing the results. Other idioms are deliberately figurative. For example, " br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beeline
A bee line is an idiom for the shortest route or a straight line between two points (see "as the crow flies"): bee line, bee-line, or beeline may also refer to: Brands and enterprises * Beeline (brand), a telecommunications brand by VimpelCom Ltd. used in Russia, other post-Soviet states, Laos, Cambodia and Vietnam * Beeline (software company) for companies to manage temporary staff * Beeline reader for adding colors to text to speed reading transitions from one line to the next Transportation * Bee Line Buzz Company, a former bus operator in Greater Manchester, United Kingdom * Bee Line Expressway, an earlier name of Florida State Road 528 east of Orlando in the United States * Bee Line Railroad, a railway in western Indiana, United States; serving Warren County and Benton County * BEE-LINE, Brussels Airlines callsign * Bee-Line Bus System of Westchester County, New York, United States * Beeline, or Okmulgee Beeline, the section of U.S. Route 75 from Tulsa to Okmulgee, Ok ...

Charles Dickens
Charles John Huffam Dickens (; 7 February 1812 – 9 June 1870) was an English writer and social critic. He created some of the world's best-known fictional characters and is regarded by many as the greatest novelist of the Victorian era.. His works enjoyed unprecedented popularity during his lifetime and, by the 20th century, critics and scholars had recognised him as a literary genius. His novels and short stories are widely read today. Born in Portsmouth, Dickens left school at the age of 12 to work in a boot-blacking factory when his father was incarcerated in a debtors' prison. After three years he returned to school, before he began his literary career as a journalist. Dickens edited a weekly journal for 20 years, wrote 15 novels, five novellas, hundreds of short stories and non-fiction articles, lectured and performed readings extensively, was an indefatigable letter writer, and campaigned vigorously for children's rights, for education, and for other social ...

Oliver Twist
''Oliver Twist; or, The Parish Boy's Progress'', Charles Dickens's second novel, was published as a serial from 1837 to 1839, and as a three-volume book in 1838. Born in a workhouse, the orphan Oliver Twist is bound into apprenticeship with an undertaker. After escaping, Oliver travels to London, where he meets the " Artful Dodger", a member of a gang of juvenile pickpockets led by the elderly criminal Fagin. ''Oliver Twist'' unromantically portrays the sordid lives of criminals, and exposes the cruel treatment of the many orphans in London in the mid-19th century. The alternative title, ''The Parish Boy's Progress'', alludes to Bunyan's '' The Pilgrim's Progress'', as well as the 18th-century caricature series by painter William Hogarth, '' A Rake's Progress'' and '' A Harlot's Progress''. In an early example of the social novel, Dickens satirises child labour, domestic violence, the recruitment of children as criminals, and the presence of street children. The novel ma ...

Swallow
The swallows, martins, and saw-wings, or Hirundinidae, are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term "swallow" is used colloquially in Europe as a synonym for the barn swallow. Around 90 species of Hirundinidae are known, divided into 19 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are nonmigratory. This family comprises two subfamilies: Pseudochelidoninae (the river martins of the genus ''Pseudochelidon'') and Hirundininae (all other swallows, martins, and saw-wings). In the Old World, the name "martin" tends to be used for the squarer-tailed species, and the name "swallow" for the more fork ...

Starling
Starlings are small to medium-sized passerine birds in the family Sturnidae. The Sturnidae are named for the genus '' Sturnus'', which in turn comes from the Latin word for starling, ''sturnus''. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species. The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common. Starlings have strong feet, their flight is strong and direct, and they are very gregarious. Their preferred ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crow's Nest
A crow's nest is a structure in the upper part of the main mast of a ship or a structure that is used as a lookout point. On ships, this position ensured the widest field of view for lookouts to spot approaching hazards, other ships, or land by using the naked eye or optical devices such as telescopes or binoculars. It should not be confused with the top, the platform in the upper part of each lower mast of a square-rigged sailing ship. According to William Scoresby Jr., the crow's nest was invented in the 19th century by his father, William Scoresby Sr., a whaler and also an Arctic explorer. However, Scoresby Sr. may simply have made an improvement on existing designs. Crow's nests appear in Egyptian reliefs as early as 1200 BC and on eighth to seventh century BC representations of Phoenician, Etruscan, and Boiotian ships. The crow’s nest disappears completely from depictions of ships after the seventh century, although the relationship between a raised vantage poin ...

Distance
Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). Since spatial cognition is a rich source of conceptual metaphors in human thought, the term is also frequently used metaphorically to mean a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between strings of text) or a degree of separation (as exemplified by distance between people in a social network). Most such notions of distance, both physical and metaphorical, are formalized in mathematics using the notion of a metric space. In the social sciences, distance can refer to a qualitative measurement of separation, such as social distance or psychological distance.

Geodesic
In geometry, a geodesic () is a curve representing in some sense the shortest path ( arc) between two points in a surface, or more generally in a Riemannian manifold. The term also has meaning in any differentiable manifold with a connection. It is a generalization of the notion of a " straight line". The noun '' geodesic'' and the adjective '' geodetic'' come from ''geodesy'', the science of measuring the size and shape of Earth, though many of the underlying principles can be applied to any ellipsoidal geometry. In the original sense, a geodesic was the shortest route between two points on the Earth's surface. For a spherical Earth, it is a segment of a great circle (see also great-circle distance). The term has since been generalized to more abstract mathematical spaces; for example, in graph theory, one might consider a geodesic between two vertices/nodes of a graph. In a Riemannian manifold or submanifold, geodesics are characterised by the property of having ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great-circle Distance
The great-circle distance, orthodromic distance, or spherical distance is the distance along a great circle. It is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior). The distance between two points in Euclidean space is the length of a straight line between them, but on the sphere there are no straight lines. In spaces with curvature, straight lines are replaced by geodesics. Geodesics on the sphere are circles on the sphere whose centers coincide with the center of the sphere, and are called 'great circles'. The determination of the great-circle distance is part of the more general problem of great-circle navigation, which also computes the azimuths at the end points and intermediate way-points. Through any two points on a sphere that are not antipodal points (directly opposite each other), there is a unique great circle. The two points separate the grea ...
