Native American Inventions And Innovations
This is an alphabetic list of Pre-columbian achievements in science and technology made by the Indigenous peoples of the Americas during the 15,000 years that they have inhabited the Americas. A * Abacus – The Aztec and Maya peoples, Maya of Mesoamerica performed arithmetic operations using an abacus. It served as a more accurate and faster alternative to a written solution or relying on memory. Archaeologists have recorded the Mesoamerican abacus, or Abacus#Native America, Nepohualtzintzin, as being present in Mesoamerica from at least between 900 and 1000 CE. * Abstract art – Abstract art was used by nearly all societies of North America, North and South America. Members of European art world believed tribal art was "primitive" until the 1890s when it served as inspiration for the modern American abstract art movement. See also Visual arts by indigenous peoples of the Americas. * Adobe – Adobe was used by the peoples from South America, Mesoamerica, and up to Southwes ...

Pre-columbian
In the history of the Americas, the pre-Columbian era spans from the original settlement of North and South America in the Upper Paleolithic period through European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures. Many pre-Columbian civilizations were marked by permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European colonies (c. late 16th–early 17th centuries), and are known only through archaeological investigations and oral history. Other civilizations were contemporary with the colonial period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own ...

Coca
Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine. The plant is grown as a cash crop in the Argentine Northwest, Bolivia, Alto Rio Negro Territory in Brazil, Colombia, Venezuela, Ecuador, and Peru, even in areas where its cultivation is unlawful. There are some reports that the plant is being cultivated in the south of Mexico, by using seeds imported from South America, as an alternative to smuggling its recreational product cocaine. It also plays a role in many traditional Amazonian and Andean cultures as well as the Sierra Nevada de Santa Marta in northern Colombia. The cocaine alkaloid content of dry ''Erythroxylum coca'' var. ''coca'' leaves was measured ranging from 0.23% to 0.96%. Coca-Cola used coca leaf extract in its products from 1885 until about 1903, when it began using decocainized leaf extract. Extraction of cocaine from coca requires severa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anesthetics
An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general anesthetics, which result in a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness. A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesiology, but others are used commonly in various fields of healthcare. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. Anesthetics are distinct from analgesics, which block only sensation of painful stimuli. Local anesthetics Local anesthetic agents prevent the transmission of nerve impulses without c ...

Iroquois
The Iroquois ( or ), officially the Haudenosaunee ( meaning "people of the longhouse"), are an Iroquoian-speaking confederacy of First Nations peoples in northeast North America/ Turtle Island. They were known during the colonial years to the French as the Iroquois League, and later as the Iroquois Confederacy. The English called them the Five Nations, comprising the Mohawk, Oneida, Onondaga, Cayuga, and Seneca (listed geographically from east to west). After 1722, the Iroquoian-speaking Tuscarora people from the southeast were accepted into the confederacy, which became known as the Six Nations. The Confederacy came about as a result of the Great Law of Peace, said to have been composed by Deganawidah the Great Peacemaker, Hiawatha, and Jigonsaseh the Mother of Nations. For nearly 200 years, the Six Nations/Haudenosaunee Confederacy were a powerful factor in North American colonial policy, with some scholars arguing for the concept of the Middle Ground, in that Eu ...

American Football
American football (referred to simply as football in the United States and Canada), also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the Glossary of American football#drive, drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins. American foot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenlandic Inuit
Greenlanders ( kl, Kalaallit / Tunumiit / Inughuit; da, Grønlændere) are people identified with Greenland or the indigenous people, the Greenlandic Inuit (''Grønlansk Inuit''; Kalaallit, Inughuit, and Tunumiit). This connection may be residential, legal, historical, or cultural. For most Greenlanders, many of these connections exist and are collectively the source of their being ''Greenlandic''. However, the term can in different contexts be delimited more precisely in different ways: as the inhabitants of Greenland, as nationals of Greenland or more broadly as persons who feel a cultural affiliation in a broad sense to Greenland. More controversial is a more recent use of the word in the sense persons of Greenlandic origin, i.e. persons whose parents were born in Greenland. The indigenous people of Greenland, or the Greenlandic Inuit, have ''indigenous status'' in the Kingdom of Denmark. Nationals of Greenland are citizens of Denmark and are overseas countries and ...

Ammassalik Wooden Maps
Ammassalik wooden maps are carved, tactile maps of the Greenlandic coastlines. In the 1880s, Gustav Holm led an expedition to the Ammassalik coast of eastern Greenland, where he met several Tunumiit, or Eastern Greenland Inuit communities, who had had no prior direct contact with Europeans. He returned to Denmark with a set of three-dimensional wooden maps of the coast around , carved by a native of Umivik named Kunit. History Kunit approached Holm on February 8, 1885, and sold the maps representing the coast from Sermiligak to Kangerdlugsuatsiak. Kunit returned on March 21 with another piece representing the peninsula between Sermiligak and Kangerdluarsikajik. Upon Holm's return, the maps were deposited along with the rest of the collection at the National Museum of Denmark in Copenhagen. As of 1948 the maps were still in Copenhagen; copies were deposited in the Musée d'Ethnographie du Trocadéro in Paris. At some point the maps were transferred to the Greenland National Muse ...

Andean Civilizations
The Andean civilizations were complex societies of many cultures and peoples mainly developed in the river valleys of the coastal deserts of Peru. They stretched from the Andes of southern Colombia southward down the Andes to Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of Peru is the oldest known civilization in the Americas, dating back to 3200 BCE. Despite severe environmental challenges, the Andean civilizations domesticated a wide variety of crops, some of which became of worldwide importance. The Andean civilizations were also noteworthy for monumental architecture, textile weaving, and many unique characteristics of the societies they created. Less than a century prior to the arrival of the Spanish conquerors, the Incas, from their homeland centered on the city of Cusco, united most of the Andean cultures into one single empire that ...

Alpaca
The alpaca (''Lama pacos'') is a species of South American camelid mammal. It is similar to, and often confused with, the llama. However, alpacas are often noticeably smaller than llamas. The two animals are closely related and can successfully crossbreed. Both species are believed to have been domesticated from their wild relatives, the vicuña and guanaco. There are two breeds of alpaca: the Suri alpaca and the Huacaya alpaca. Alpacas are kept in herds that graze on the level heights of the Andes of Southern Peru, Western Bolivia, Ecuador, and Northern Chile at an altitude of above sea level. Alpacas are considerably smaller than llamas, and unlike llamas, they were not bred to be working animals, but were bred specifically for their fiber. Alpaca fiber is used for making knitted and woven items, similar to sheep's wool. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles, and ponchos, in South America, as well as sweaters, soc ...

Almanacs
An almanac (also spelled ''almanack'' and ''almanach'') is an annual publication listing a set of current information about one or multiple subjects. It includes information like weather forecasts, farmers' planting dates, tide tables, and other tabular data often arranged according to the calendar. Celestial figures and various statistics are found in almanacs, such as the rising and setting times of the Sun and Moon, dates of eclipses, hours of high and low tides, and religious festivals. The set of events noted in an almanac may be tailored for a specific group of readers, such as farmers, sailors, or astronomers. Etymology The etymology of the word is disputed. The earliest documented use of the word in any language is in Latin in 1267 by Roger Bacon, where it meant a set of tables detailing movements of heavenly bodies including the Moon. It has been suggested that the word ''almanac'' derives from a Greek word meaning ''calendar''. However, that word appears o ...

Alcohol By Volume
Alcohol by volume (abbreviated as ABV, abv, or alc/vol) is a standard measure of how much alcohol (ethanol) is contained in a given volume of an alcoholic beverage (expressed as a volume percent). It is defined as the number of millilitres (mL) of pure ethanol present in of solution at . The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at , which is . The ABV standard is used worldwide. The International Organization of Legal Metrology has ethanol (data page)#Properties of aqueous ethanol solutions, tables of density of water–ethanol mixtures at different concentrations and temperatures. In some countries, e.g. France, alcohol by volume is often referred to as degrees Gay-Lussac (after the French chemist Joseph Louis Gay-Lussac), although there is a slight difference since the Gay-Lussac convention uses the International Standard Atmosphere value for temperature, .
