Monkey Bar
A jungle gym (called a climbing frame in British English) is a piece of playground equipment made of many pieces of material, such as plumbing, metal pipes or ropes, on which participants can climb, hang, sit, and—in some configurations—slide. Monkey bars are a part of a jungle gym where a user, hanging in the air, swings between evenly spaced horizontal bars. In Australian English, the term "monkey bars" is sometimes used to refer to the entire jungle gym. History The first jungle gym was invented in 1920 and patented by lawyer Sebastian Hinton in Chicago. It was sold under the trademarked name Junglegym™. Hinton's second prototype "jungle gym" is still standing at Crow Island School in Winnetka, Illinois. The term "monkey bars" appears at least as far back as the 1930s, though Hinton's initial 1920 patent appeals to the "monkey instinct" in claiming the benefits of climbing as exercise and play for children, and his improvement patents later that year refer to monkeys sha ...

Charles Howard Hinton
Charles Howard Hinton (1853 – 30 April 1907) was a British mathematician and writer of science fiction Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel unive ... works titled ''Scientific Romances''. He was interested in n-dimensional space, higher dimensions, particularly the Four-dimensional space, fourth dimension. He is known for coining the word "tesseract" and for his work on methods of visualising the geometry of higher dimensions. Life Hinton's father, James Hinton (surgeon), James Hinton, was a surgeon and advocate of polygamy. Charles Hinton was born in the United Kingdom. His siblings included the costume designer Ada Nettleship (1856 – 1932). Hinton taught at Cheltenham College while he studied at Balliol College, Oxford, where he obtained his B.A. in 1877. From 1880 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachiation
Brachiation (from "brachium", Latin for "arm"), or arm swinging, is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. During brachiation, the body is alternately supported under each forelimb. This form of locomotion is the primary means of locomotion for the small gibbons and siamangs of southeast Asia. Gibbons in particular use brachiation for as much as 80% of their locomotor activities. Some New World monkeys, such as spider monkeys and muriquis, were initially classified as ''semibrachiators'' and move through the trees with a combination of leaping and brachiation. Some New World species also practice suspensory behaviors by using their prehensile tail, which acts as a fifth grasping hand. Evidence has shown that the extinct ape ''Proconsul'' from the Miocene of East Africa developed an early form of suspensory behaviour, and was therefore referred to as a ''probrachiator.''

Outdoor Playset
An outdoor playset is a structure erected outside for children to play on and around. Components Typical components of an outdoor playset include: * Towers. In a playset, a tower is a vertical structure with one or more decks placed at various levels. A deck is essentially a horizontal play surface contained within or attached to a tower. * Bridges. Towers may be connected to one another via fixed bridges or chain bridges for children to walk across. * Ladders. Rope ladders and fixed ladders are common accessories for playsets. * Sandboxes. A sandbox often accompanies an outdoor playset. * Slides. Playground slides may be covered or uncovered. * Swings. Swings are usually mounted on a free-standing swing set. * Monkey bars. Towers may be connected by monkey bars as well as bridges. Safety In July 2001, the U.S. Consumer Product Safety Commission (CPSC) reported that each year, more than 200,000 children are taken to hospital emergency rooms due to playground-related injuri ...

National Safety Council
The National Safety Council (NSC) is a 501(c)(3) nonprofit, public service organization promoting health and safety in the United States. Headquartered in Itasca, Illinois, NSC is a member organization, founded in 1913 and granted a congressional charter in 1953. Members include more than 55,000 businesses, labor organizations, schools, public agencies, private groups and individuals. The group focuses on areas where the greatest number of preventable injuries and deaths occur, including workplace safety, prescription medication abuse, teen driving, cell phone use while driving and safety in homes and communities. History In 1912, the first Cooperative Safety Congress was held in Milwaukee, Wisconsin. The event was sponsored by the Association of Iron and Steel Electrical Engineers (a predecessor of the Association for Iron and Steel Technology). The approximately 200 attendees, representing industry and government, resolved to “organize and create a permanent body for th ...

Woodchips
Woodchips are small- to medium-sized pieces of wood formed by cutting or chipping larger pieces of wood such as trees, branches, logging residues, stumps, roots, and wood waste. Woodchips may be used as a biomass solid fuel and are raw material for producing wood pulp. They may also be used as an organic mulch in gardening, landscaping, and ecosystem restoration; in bioreactors for denitrification; and as a substrate for mushroom cultivation. The process of making woodchips is called wood chipping and is done using a wood chipper. The types of woodchips formed following chipping is dependent on the type of wood chipper used and the material from which they are made. Woodchip varieties include: forest chips (from forested areas), wood residue chips (from untreated wood residues, recycled wood and off-cuts), sawing residue chips (from sawmill residues), and short rotation forestry chips (from energy crops). Raw materials The raw materials of woodchips can be pulpwood, waste wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartesian Coordinates
A Cartesian coordinate system (, ) in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length. Each reference coordinate line is called a ''coordinate axis'' or just ''axis'' (plural ''axes'') of the system, and the point where they meet is its ''origin'', at ordered pair . The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin. One can use the same principle to specify the position of any point in three-dimensional space by three Cartesian coordinates, its signed distances to three mutually perpendicular planes (or, equivalently, by its perpendicular projection onto three mutually perpendicular lines). In general, ''n'' Cartesian coordinates (an element of real ''n''-space) specify the point in an ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-dimensional Space
Three-dimensional space (also: 3D space, 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called ''parameters'') are required to determine the position (geometry), position of an element (i.e., Point (mathematics), point). This is the informal meaning of the term dimension. In mathematics, a tuple of Real number, numbers can be understood as the Cartesian coordinates of a location in a -dimensional Euclidean space. The set of these -tuples is commonly denoted \R^n, and can be identified to the -dimensional Euclidean space. When , this space is called three-dimensional Euclidean space (or simply Euclidean space when the context is clear). It serves as a model of the physical universe (when relativity theory is not considered), in which all known matter exists. While this space remains the most compelling and useful way to model the world as it is experienced, it is only one example of a large variety of spaces in three dimensions called ...

British English
British English (BrE, en-GB, or BE) is, according to Lexico, Oxford Dictionaries, "English language, English as used in Great Britain, as distinct from that used elsewhere". More narrowly, it can refer specifically to the English language in England, or, more broadly, to the collective dialects of English throughout the British Isles taken as a single umbrella variety, for instance additionally incorporating Scottish English, Welsh English, and Ulster English, Northern Irish English. Tom McArthur (linguist), Tom McArthur in the ''Oxford Guide to World English'' acknowledges that British English shares "all the ambiguities and tensions [with] the word 'British people, British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity". Variations exist in formal (both written and spoken) English in the United Kingdom. For example, the adjective ''wee'' is almost exclusively used in parts of Scotland, North E ...
