A boomerang is a thrown tool, typically constructed as a flat aerofoil, that is designed to spin about an axis perpendicular to the direction of its flight.
A returning boomerang is designed to circle back to the thrower.
Boomerangs are used as a weapon for hunting purposes, usually by tribes. It is also used for sports or for entertainment purposes.
A boomerang is usually thought of as a wooden device cut from a tree trunk, although historically boomerang-like devices have also been made from bones. Modern boomerangs used for sport are often made from carbon fiber-reinforced plastics or other high-tech materials. Boomerangs come in many shapes and sizes depending on their geographic or tribal origins and intended function.
An important distinction should be made between returning boomerangs and non-returning boomerangs. Returning boomerangs actually do fly and are examples of the earliest heavier than air man made flight. A returning boomerang has two or more airfoil wings arranged so that the spinning creates unbalanced aerodynamic forces that curve its path so that it travels in an elliptical path and returns to its point of origin when thrown correctly. While a throwing stick can also be shaped overall like a returning boomerang, it is designed to travel as straight as possible so that it can be aimed and thrown with great force to bring down game. Its surfaces therefore are symmetrical and not uneven like the airfoils which give the returning boomerang its characteristic curved flight.
Latin America (Spanish: América Latina or Latinoamérica; Portuguese: América Latina; French: Amérique latine) is a region of the Americas where Romance languages (i.e., those derived from Latin) – particularly Spanish and Portuguese, and variably French – are primarily spoken. Latin America has an area of approximately 21,069,500 km² (7,880,000 sq mi), almost 3.9% of the Earth's surface or 14.1% of its land surface area. As of 2010, its population was estimated at more than 590 million and its combined GDP at 5.16 trillion United States dollars (6.27 trillion at PPP). The Latin American expected economic growth rate is at about 5.7% for 2010 and 4% in 2011. According to Phelan (1968, p. 296), the term "Latin America" was baptized in 1861 in La revue des races Latines, a magazine 'dedicated to the cause of Pan-Latinism'.
Latin America can be subdivided into several subregions based on geography, politics, demographics and culture. The basic geographical subregions are North America, Central America, the Caribbean and South America; the latter contains further politico-geographical subdivisions such as the Southern Cone and the Andean states. It may be subdivided on linguistic grounds into Hispanic America and Portuguese America.
Latin ( /ˈlætɪn/; Latin: lingua latīna; IPA: [laˈtiːna]) is an Italic language originally spoken in Latium and Ancient Rome. It, along with most European languages, is a descendant of the ancient Proto-Indo-European language. It originated in the Italian peninsula. Although it is considered a dead language, many students, scholars and members of the Christian clergy speak it fluently, and it is still taught in some primary and secondary and many post-secondary educational institutions around the world: in particular, there has been some revival of interest in American schools. Latin is still used in the creation of new words in modern languages of many different families, including English, and in biological taxonomy. Latin and its daughter Romance languages are the only surviving languages of the Italic language family. Other languages of the Italic branch are attested in the inscriptions of early Italy, but were assimilated to Latin during the Roman Republic.
