Placeholder Name
Placeholder names are intentionally overly generic and ambiguous terms referring to things, places, or people, the names of which or of whom do not actually exist; are temporarily forgotten, or are unimportant; or in order to avoid stigmatization, or because they are unknowable or unpredictable given the context of their discussion; or to deliberately expunge direct use of the name. Placeholder names for people are often terms referring to an average person or a predicted persona of a typical user. Linguistic role These placeholders typically function grammatically as nouns and can be used for people (e.g. '' John Doe, Jane Doe''), objects (e.g. '' widget''), locations ("Main Street"), or places (e.g. ''Anytown, USA''). They share a property with pronouns because their referents must be supplied by context; but, unlike a pronoun, they may be used with no referent—the important part of the communication is not the thing nominally referred to by the placeholder, but ...

Cotton Gin
A cotton gin—meaning "cotton engine"—is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.. Reprinted by McGraw-Hill, New York and London, 1926 (); and by Lindsay Publications, Inc., Bradley, Illinois, (). The separated seeds may be used to grow more cotton or to produce cottonseed oil. Handheld roller gins had been used in the Indian subcontinent since at earliest 500 and then in other regions. The Indian worm gear, worm-gear roller gin was invented sometime around the 16th century and has, according to Lakwete, remained virtually unchanged up to the present time. A modern mechanical cotton gin was created by English-American inventor Eli Whitney in 1793 and patented in 1794. Whitney's gin used a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously removed the loose cotton lint to prevent jams. It revolutionized the cotton indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

X-ray
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 Nanometre, nanometers to 10 Picometre, picometers, corresponding to frequency, frequencies in the range of 30 Hertz, petahertz to 30 Hertz, exahertz ( to ) and photon energies in the range of 100 electronvolt, eV to 100 keV, respectively. X-rays were discovered in 1895 in science, 1895 by the German scientist Wilhelm Röntgen, Wilhelm Conrad Röntgen, who named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medical diagnostics (e.g., checking for Bo ...

Blackacre
Blackacre, Whiteacre, Greenacre, Brownacre, and variations are the placeholder names used for fictitious estate (law), estates in land. The names are used by professors of law in common law jurisdictions, particularly in the area of real property and occasionally in contracts, to discuss the rights of various parties to a piece of land. A typical law school or bar exam question on real property might say: Where more than one estate is needed to demonstrate a pointperhaps relating to a dispute over boundaries, easements or riparian rightsa second estate will usually be called Whiteacre, a third, Greenacre, and a fourth, Brownacre. Origin Jesse Dukeminier, author of one of the leading series of textbooks on property, traces the use of Blackacre and Whiteacre for this purpose to a 1628 treatise by Sir Edward Coke. Dukeminier suggests that the term might originate with references to colors associated with certain agriculture, crops ("peas and beans are black, cereal, corn and potat ...

Widget (economics)
The word ''widget'' is a placeholder name for an object or, more specifically, a mechanical or other manufactured device. It is an ''abstract unit of production''. The ''Oxford English Dictionary'' defines it as "An indefinite name for a gadget or mechanical contrivance, esp. a small manufactured item" and dates this use back to 1931. It states that the origin is "perhaps U.S." and for etymology suggests that it may be a variant of ''gadget''. The term also appears earlier in George S. Kaufman and Moss Hart's 1924 play '' Beggar on Horseback''. General Motors Corporation sponsored a short film in 1939, "Round and Round", which features widgets throughout. Usage When discussing a hypothetical situation, the term is used to represent any type of personal property, with the corresponding term Blackacre used to represent any type of real property. In such use, the widget or Blackacre has whatever characteristics are relevant to the scenario. So, if the object being discussed nee ...

Cookware And Bakeware
Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware. There is a great variety of cookware and bakeware in shape, material, and inside surface. Some materials conduct heat well; some retain heat well. Some surfaces are non-stick; some require seasoning. Some pots and their lids have handles or knobs made of low thermal conductance materials such as bakelite, plastic or wood, which make them easy to pick up without oven gloves. A good cooking pot design has an "overcook edge" which is what the lid lies on. The lid has a dripping edge that prevents condensation fluid from dripping off when handling the lid (taking it off and holding it 45°) or putting it down. History The history of cooking vessels before the development of pottery is minimal due to the limited arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tool
A tool is an Physical object, object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many Tool use by animals, animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as Rock (geology), stone, bone, and wood, were used for the preparation of food, hunting, the manufacture of weapons, and the working of materials to produce clothing and useful Cultural artifact, artifacts and crafts such as pottery, along with the construction of housing, businesses, infrastructure, and transportation. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as Working animal, animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution markin ...

Cultural Artifact
A cultural artifact, or cultural artefact (see American and British English spelling differences), is a term used in the social sciences, particularly anthropology, ethnology and sociology for anything created by humans which gives information about the culture of its creator and users. ''Artifact'' is the spelling in North American English; ''artefact'' is usually preferred elsewhere. Cultural artifact is a more generic term and should be considered with two words of similar, but narrower, nuance: it can include objects recovered from archaeological sites, i.e. archaeological artifacts, but can also include objects of modern or early-modern society, or social artifacts. For example, in an anthropological context, a 17th-century lathe, a piece of faience, or a television Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Tele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
