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.

The name shuttlecock is frequently shortened to shuttle. The "shuttle" part of the name was probably derived from its back-and-forth motion during the game, resembling the shuttle of a loom; the "cock" part of the name was probably derived from the resemblance of the feathers to those on a cockerel.

The "Shuttlecock" also used in traditional Chinese sports called "TiJianZi" by Chinese spelling, or "Shuttlecock kicking" in English. There is a lot of kinds and sizes of shuttlecock in the sports. The shuttlecock by size 14-15x14-15x14-15cm of weight 24-25 grams is called "Middle Shuttlecock", usually used in "Chinese JJJ" game. It's a most popular shuttlecock kicking game with 90cm height middle net and using inner lines of badminton court, which invented by Mr. John Du in May of 2009. Chinese JJJ uses Soccer's shooting goal techniques in the game, making the shuttlecock sports much closer to Soccer Sports which is the first time happened in the history.

Feathered vs. synthetic shuttlecocks

The cost of good quality feathers is similar to that of good quality plastics, but plastics are far more durable, typically lasting many matches without any impairment to their flight. For this reason, many clubs prefer to play with plastics.

The playing characteristics of plastics and feathers are substantially different. Plastics fly more slowly on initial impact, but slow down less towards the end of their flight. Feather shuttles may come off the strings at speeds in excess of 320 km/h (200 mph) but slow down faster as they drop. For this reason, the feather shuttle makes the game seem faster, but also allows more time to play strokes.

Most experienced and skillful players greatly prefer feathers, and serious tournaments or leagues are always played using feather shuttlecocks. Experienced players generally prefer the "feel" of feathered shuttlecocks, and assert that they are better able to control the flight of feathers than of plastics. Because feather shuttles fly more quickly off the racquet face they also tend to cause less shoulder impact and injury. In Asia, where feather shuttlecocks are more affordable than in Europe and North America, plastic shuttlecocks are hardly used at all. All senior international tournaments use only feather shuttlecocks of the highest quality.. Also as opposed to feathers that self correct and drop straight down on the clear shot, plastic never quite returns to a straight drop falling more on a diagonal.

A settler is a person who has migrated to an area and established permanent residence there, often to colonize the area. Settlers are generally people who take up residence on land and cultivate it, as opposed to nomads. Settlers are sometimes termed "colonists" or "colonials" and—in the United States -- "pioneers".

Terminology

Historical usage

In almost every real historical case, settlers live on land which previously belonged to long-established peoples, known as indigenous people (often called "natives", "Aborigines" or, in the Americas, "Indians"). This land is usually settled against the wishes of the indigenes, and then controlled, defended and expanded by force, or it is bought or leased from indigenous people on terms highly favourable to the settlers, sometimes under a treaty (e.g. the Treaty of Waitangi in New Zealand). In some cases (such as Australia), the legal ownership of some lands is contested much later by indigenous people, who seek or claim traditional usage, land rights, native title and related forms of ownership or partial control.

The word "settler" was not originally usually used in relation to unfree labour immigrants, such as slaves (e.g. in the United States), indentured labourers (such as in Colonial America), or convicts (such as in New York, 1674–1775; Australia 1788-1868).

In the figurative usage a "person who goes first or does something first", also applies to the American English use of "pioneer" to refer to a settler, a person who has migrated to a less occupied area and established permanent residence there, often to colonize the area, first recorded in English in 1605. In United States history it refers to those people who helped to settle new lands.

In this usage, pioneers are usually among the first to an area, whereas settlers can arrive after first settlement and join others in the process of human settlement. This correlates with the work of military pioneers who were tasked with construction of camps before the rest of the troops would arrive at the designated camp site.

More recently descendants of these immigrants may argue that they have as much right to use the word "settler" as the descendants of free immigrants.

settlers in the Caucasus region, circa 1910]] In Imperial Russia, the government invited Russians or foreign nationals to settle in sparsely populated lands. These settlers were called "colonists". See, e.g., articles Slavo-Serbia, Volga German, Volhynia, Russians in Kazakhstan.

Although they are often thought of as traveling by sea — the dominant form of travel in the early modern era — significant waves of settlement could also use long overland routes, such as the Great Trek by the Boer-Afrikaners in South Africa, or the Oregon Trail in the United States.

Anthropological usage

Modern usage

In the Middle East, Israeli settlers are Jews who live in areas captured during the Six-Day war and claimed by Palestinians and Syria. Some historians and scientists maintain that Palestinians are descended mostly from Arab settlers in Palestine, after the Caliphate conquered the area in the 7th century. However, both Israelis and Palestinians claim partial descent from peoples who lived in the region in prehistoric times (see: History of ancient Israel and Judah, Ancestry of the Palestinians).

Other usages

Causes of emigration

The reasons for the emigration of settlers vary, but often they include the following factors and incentives: the desire to start a new and better life in a foreign land, personal financial hardship, social, cultural, ethnic, or religious persecution (e.g. the Pilgrims, Mormons and Zionists), political oppression, and government incentive policies aimed at encouraging foreign settlement.

The colony concerned is sometimes controlled by the government of a settler's home country, and emigration is sometimes approved by an imperial government.
