Shuttlecock
A shuttlecock (also called a birdie or shuttle) is a high-drag projectile used in the sport of badminton. It has an open conical shape formed by feathers or plastic (or a synthetic alternative) embedded into a rounded cork (or rubber) base. The shuttlecock's shape makes it extremely aerodynamically stable. Regardless of initial orientation, it will turn to fly cork first, and remain in the cork-first orientation. Origins The object resembles a hawk's lure, used from ancient times in the training of hunting birds. It is frequently shortened to shuttle. The "shuttle" part of the name is derived from its back-and-forth motion during the game, resembling the shuttle of a 14th-century loom, while the "cock" part of the name is derived from the resemblance of the feathers to those on a rooster. Specifications A regulation standard shuttlecock weighs around . It has 16 feathers with each feather in length, and the diameter of the cork is . The diameter of the circle that the feat ...

Jianzi
Jianzi (), tī jianzi (踢毽子), tī jian (踢毽) or jianqiú (毽球), is a traditional Chinese national sport in which players aim to keep a heavily weighted shuttlecock in the air by using their bodies, apart from the hands, unlike in similar games Peteca and Indiaca. The primary source of jianzi is a Chinese ancient game called '' Cuju'' of the Han dynasty 2,000 years ago. Jianzi's competitive sport types are played on a badminton court using inner or outer lines in different types of jianzi's competitive sports, respectively. It can also be played artistically, among a circle of players in a street or park, with the objective to keep the shuttle 'up' and show off skills. In Vietnam, it is known as ''đá cầu'' and is the national sport. In the Philippines, it is known as ''sipa'' and was also the national sport until it was replaced by arnis in December 2009. In recent years, the game has gained a formal following in around the globe. In English, both the sport and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Badminton
Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" (with one player per side) and "doubles" (with two players per side). Badminton is often played as a casual outdoor activity in a yard or on a beach; formal games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the racquet and landing it within the opposing side's half of the court. Each side may only strike the shuttlecock once before it passes over the net. Play ends once the shuttlecock has struck the floor or if a fault has been called by the umpire, service judge, or (in their absence) the opposing side. The shuttlecock is a feathered or (in informal matches) plastic projectile which flies differently from the balls used in many other sports. In particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly. Sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battledore And Shuttlecock
Battledore and shuttlecock, or jeu de volant, is an early sport related to modern badminton. The game is played by two or more people using small rackets (battledores), made of parchment or rows of gut stretched across wooden frames, and shuttlecocks, made of a base of some light material, such as cork, with trimmed feathers fixed around the top. The object is for players to bat the shuttlecock from one to the other as many times as possible without allowing it to fall to the ground. History Games with a shuttlecock are attested to as early as 2,000 years ago, and have been popular in India, China, Japan, and Siam. Various traditional shuttlecock games have been played by North American indigenous peoples, including the Kwakiutl, Pima, Salish, and Zuni; they are often played with a feathered shuttle made of corn husk or twigs and sometimes a wooden battledore.Tara Prindle"Cornhusk Shuttlecock Game" NativeTech.org.

Aerodynamic
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for ...

Lure (falconry)
A lure is an object used in falconry, usually made of leather with a pair of bird wings or feathers attached. It is often an effigy of a prey species or preferred quarry. A falconer swings the lure round and round on a cord for the falcon Falcons () are birds of prey in the genus ''Falco'', which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene. Adult falcons ... to chase for exercise. There are at least three types of lure-flying. Short line, long line and pole luring. A lure also may be used as an object to call the falcon, hawk or eagle to return.

Shuttle (weaving)
A shuttle is a tool designed to neatly and compactly store a holder that carries the thread of the weft yarn while weaving with a loom. Shuttles are thrown or passed back and forth through the shed, between the yarn threads of the warp in order to weave in the weft. The simplest shuttles, known as "stick shuttles", are made from a flat, narrow piece of wood with notches on the ends to hold the weft yarn. More complicated shuttles incorporate bobbins or pirns. In the United States, shuttles are often made of wood from the flowering dogwood, because it is hard, resists splintering, and can be polished to a very smooth finish. In the United Kingdom shuttles were usually made of boxwood, cornel, or persimmon. Flying shuttle Shuttles were originally passed back and forth by hand. However, John Kay invented a loom in 1733 that incorporated a flying shuttle. This shuttle could be thrown through the warp, which allowed much wider cloth to be woven much more quickly and made the develo ...

Loom
A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same. Etymology and usage The word "loom" derives from the Old English ''geloma'', formed from ''ge-'' (perfective prefix) and ''loma'', a root of unknown origin; the whole word ''geloma'' meant a utensil, tool, or machine of any kind. In 1404 "lome" was used to mean a machine to enable weaving thread into cloth. By 1838 "loom" had gained the additional meaning of a machine for interlacing thread. Weaving Weaving is done by intersecting the longitudinal threads, the warp, i.e. "that which is thrown across", with the transverse threads, the weft, i.e. "that which is woven". The major components of the loom are the warp beam, heddles, harnesses or shafts (as few as two, four is common, sixteen not unheard of), s ...

Rooster
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature.
