Backscratcher
A backscratcher (occasionally known as a scratch-back) is a tool used for relieving an itch in an area that cannot easily be reached just by one's own hands, typically the back. Composition and variation They are generally long, slender, rod-shaped, tools good for scratching one's back, with a knob on one end for holding and a rake-like device, sometimes in the form of a human hand, on the other end to perform the actual scratching. Many others are shaped like horse hooves, claws, or are retractable, to reach further down the back. Though a backscratcher could feasibly be fashioned from most materials, most modern backscratchers are made of plastic, though examples can be found made of wood, whalebone, tortoiseshell, horn, cane, bamboo, ivory, baleen and in some cases in history, narwhal tusks, due to the status afforded by relieving itches with a supposed unicorn horn (an example of conspicuous consumption). Backscratchers vary in length between 12 and 24 ins. (30–60&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baleen
Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales. Depending on the species, a baleen plate can be long, and weigh up to . Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness. Baleen plates are broader at the gumline (base). The plates have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinese Inventions
China has been the source of many innovations, scientific discoveries and inventions. This includes the ''Four Great Inventions'': papermaking, the compass, gunpowder, and printing (both woodblock and movable type). The list below contains these and other inventions in ancient and modern China attested by archaeological or historical evidence, excluding prehistoric inventions of Neolithic and early Bronze Age China. The historical region now known as China experienced a history involving mechanics, hydraulics and mathematics applied to horology, metallurgy, astronomy, agriculture, engineering, music theory, craftsmanship, naval architecture and warfare. Use of the plow during the Neolithic period Longshan culture (c. 3000–c. 2000 BC) allowed for high agricultural production yields and rise of Chinese civilization during the Shang Dynasty (c. 1600–c. 1050 BC). Later inventions such as the multiple-tube seed drill and the heavy moldboard iron plow enabled Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Chambers (journalist)
Robert Chambers (; 10 July 1802 – 17 March 1871) was a Scottish publisher, geologist, evolutionary thinker, author and journal editor who, like his elder brother and business partner William Chambers, was highly influential in mid-19th-century scientific and political circles. Chambers was an early phrenologist in the Edinburgh Phrenological Society. He was also the anonymous author of ''Vestiges of the Natural History of Creation'', which was so controversial that his authorship was not acknowledged until after his death. Early life Chambers was born in Peebles in the Scottish Borders 10 July 1802 to Jean Gibson (''c''. 1781–1843) and James Chambers, a cotton manufacturer. He was their second son of six children. The town had changed little in centuries. The town had old and new parts, each consisting of little more than a single street. Peebles was mainly inhabited by weavers and labourers living in thatched cottages. His father, James Chambers, made his living as a co ...

Chambers Book Of Days
''Chambers Book of Days'' (''The Book of Days: A Miscellany of Popular Antiquities in Connection with the Calendar, Including Anecdote, Biography, & History, Curiosities of Literature and Oddities of Human Life and Character'') was written by the Scottish author Robert Chambers and first published in 1864. A new version of ''Chambers Book of Days'' was published by Chambers Harrap in 2004. ''The Book of Days'' (1864) ''The Book of Days'' was Robert Chambers' last publication, and perhaps his most elaborate. It was a huge collection of short, largely factual pieces which today would generally be bracketed as "trivia" but very interesting trivia. The formula has been much repeated. It is supposed that his excessive labour in connection with this book hastened his death. It was published in two large volumes, each over 840 pages long, and, for its day, was well-illustrated with engraved drawings linked to the articles. Its full title is ''The Book of Days: A Miscellany of Popula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiricahua
Chiricahua ( ) is a band of Apache Native Americans. Based in the Southern Plains and Southwestern United States, the Chiricahua (Tsokanende ) are related to other Apache groups: Ndendahe (Mogollon, Carrizaleño), Tchihende (Mimbreño), Sehende (Mescalero), Lipan, Salinero, Plains, and Western Apache. Chiricahua historically shared a common area, language, customs, and intertwined family relations with their fellow Apaches. At the time of European contact, they had a territory of 15 million acres (61,000 km2) in Southwestern New Mexico and Southeastern Arizona in the United States and in Northern Sonora and Chihuahua in Mexico. Today Chiricahua are enrolled in three federally recognized tribes in the United States: the Fort Sill Apache Tribe, located near Apache, Oklahoma, with a small reservation outside Deming, New Mexico; the Mescalero Apache Tribe of the Mescalero Reservation near Ruidoso, New Mexico; and the San Carlos Apache Tribe in southeastern Arizona.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or ...

Claw
A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws. A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and grooming, in those and other species. Similar appendages that are flat and do not come to a sharp point are called nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named spurs. Tetrapods In tetrapods, claws are made of keratin and consist of two layers. The unguis is the harder external layer, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inuit
Inuit (; iu, ᐃᓄᐃᑦ 'the people', singular: Inuk, , dual: Inuuk, ) are a group of culturally similar indigenous peoples inhabiting the Arctic and subarctic regions of Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, and Alaska. Inuit languages are part of the Eskimo–Aleut languages, also known as Inuit-Yupik-Unangan, and also as Eskaleut. Inuit Sign Language is a critically endangered language isolate used in Nunavut. Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, Nunatsiavut and NunatuKavut in Labrador, and in various parts of the Northwest Territories, particularly around the Arctic Ocean, in the Inuvialuit Settlement Region. With the exception of NunatuKavut, these areas are known, primarily by Inuit Tapiriit Kanatami, as Inuit Nunangat. In Canada, sections 25 and 35 of the Constitution Act of 1982 classify Inuit as a distinctive group of Aboriginal Canadians wh ...
