Marble Games
A marble is a small spherical object often made from glass, clay, steel, plastic, or agate. These toys can be used for a variety of games called marbles, as well being placed in marble runs or races, or created as a form of art. They are often collected, both for nostalgia and for their aesthetic colors. Sizes may vary, but usually range from about in diameter. In the north of England the game and objects are called "taws", with larger taws being called "bottle washers", named after the use of a marble in Codd-neck bottles, which were often collected for play. Games History In the early twentieth century, small balls of stone from about 2500 BCE, identified by archaeologists as marbles, were found by excavation near Mohenjo-daro, in a site associated with the Indus Valley civilization. In modern India the game is called "kanche". Marbles are often mentioned in Roman literature, as in Ovid's poem "Nux" (which mentions playing the game with walnuts), and there are many examp ...

Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO3) or Dolomite (mineral), dolomite (CaMg(CO3)2) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not Foliation (geology), foliated (Layered intrusion, layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The extraction of marble is performed by quarrying. Marble production is dominated by four countries: China, Italy, India and Spain, which account for almost half of world production of marble and decorative stone. Because of its high hardness and strong wear resistance, and because it will not be deformed by temperature, marble is often used in Marble sculpture, sculpture and construction. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Countries
The Low Countries (; ), historically also known as the Netherlands (), is a coastal lowland region in Northwestern Europe forming the lower Drainage basin, basin of the Rhine–Meuse–Scheldt delta and consisting today of the three modern "Benelux" countries: Belgium, Luxembourg, and the Netherlands (, which is singular). Geographically and historically, the area can also include parts of France (such as Nord (French department), Nord and Pas-de-Calais) and the Germany, German regions of East Frisia, Geldern, Guelders and Cleves. During the Middle Ages, the Low Countries were divided into numerous semi-independent principalities. Historically, the regions without access to the sea linked themselves politically and economically to those with access to form various unions of ports and hinterland, stretching inland as far as parts of the German Rhineland. Because of this, nowadays not only physically low-altitude areas, but also some hilly or elevated regions are considered part of ...

Mass Production
Mass production, also known as mass production, series production, series manufacture, or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. The term ''mass production'' was popularized by a 1926 article in the ''Encyclopædia Britannica'' supplement that was written based on correspondence with Ford Motor Company. ''The New York Times'' used the term in the title of an article that appeared before the publication of the ''Britannica'' article. The idea of mass production is applied to many kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to clothing, textiles, parts and assemblies of parts ( household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
