Jungle Gym
A jungle gym (called a climbing frame in British English) is a piece of playground equipment made of many pieces of material, such as 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. 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 the Winnetka Historical Society where it was relocated from the 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 ...

Charles Howard Hinton
Charles Howard Hinton (1853 – 30 April 1907) was a British mathematician and writer of science fiction 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 England. 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 1886, he taught at Uppingham School in Rutland, where Howard Candler, a friend of Edwin Abbott Abbott's, also taught. Hinton also received his M.A. from Oxford in 1886. In 1880, Hinton married Mary Ellen Boole, daughter of Mary Everest Boole and George Boole, th ... [...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. * Seesaws. Seesaws are a long, narrow board supported by a single pivot point. * 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 f ...

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, Tree stump, 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 Woodchipper, 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 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Tribune
The ''Chicago Tribune'' is an American daily newspaper based in Chicago, Illinois, United States. Founded in 1847, it was formerly self-styled as the "World's Greatest Newspaper", a slogan from which its once integrated WGN (AM), WGN radio and WGN-TV, WGN television received their call letters. It is the most-read daily newspaper in the Chicago metropolitan area and the Great Lakes region, and the List of newspapers in the United States, sixth-largest newspaper by print circulation in the United States. In the 1850s, under Joseph Medill, the ''Chicago Tribune'' became closely associated with the Illinois politician Abraham Lincoln, and the then new Republican Party (United States), Republican Party's progressive wing. In the 20th century, under Medill's grandson 'Colonel' Robert R. McCormick, its reputation was that of a crusading newspaper with an outlook that promoted Conservatism in the United States, American conservatism and opposed the New Deal. Its reporting and commenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartesian Coordinates
In geometry, a Cartesian coordinate system (, ) in a plane is a coordinate system that specifies each point uniquely by a pair of real numbers called ''coordinates'', which are the signed distances to the point from two fixed perpendicular oriented lines, called '' coordinate lines'', ''coordinate axes'' or just ''axes'' (plural of ''axis'') of the system. The point where the axes meet is called the '' origin'' and has as coordinates. The axes directions represent an orthogonal basis. The combination of origin and basis forms a coordinate frame called the Cartesian frame. Similarly, the position of any point in three-dimensional space can be specified by three ''Cartesian coordinates'', which are the signed distances from the point to three mutually perpendicular planes. More generally, Cartesian coordinates specify the point in an -dimensional Euclidean space for any dimension . These coordinates are the signed distances from the point to mutually perpendicular fixed h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-dimensional Space
In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values ('' coordinates'') are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space. More general three-dimensional spaces are called '' 3-manifolds''. The term may also refer colloquially to a subset of space, a ''three-dimensional region'' (or 3D domain), a '' solid figure''. Technically, a tuple of 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 pair formed by a -dimensional Euclidean space and a Cartesian coordinate system. When , this space is called the three-dimensional Euclidean space (or simply "Euclidean space" when the context is clear). In classical physics, it serve ...
