Darts (other)
Darts is a competitive sport in which two or more players bare-handedly throw small sharp-pointed projectiles known as darts at a round target known as a dartboard. Points can be scored by hitting specific marked areas of the board, though unlike in sports such as archery, these areas are distributed all across the board and do not follow a principle of points increasing toward the board's bullseye. Though a number of similar games using various boards and rules exist, the term "darts" usually now refers to a standardised game involving a specific board design and set of rules. Darts is both a professional throwing sport and a traditional pub game. Darts is commonly played in the British Isles, and recreationally enjoyed around the world. History In 1908, darts was declared to be a game of skill and was thus allowed to be played in pubs.

Professional Darts Corporation
The Professional Darts Corporation (PDC) is a professional darts organisation in the United Kingdom, established in 1992 when a group of leading players split from the British Darts Organisation (BDO) to form what was initially called the World Darts Council (WDC). Sports promoter Eddie Hearn is the PDC chairman. The PDC developed and holds several competitions, including the annual PDC World Darts Championship, the World Matchplay (darts), World Matchplay, World Grand Prix (darts), World Grand Prix, UK Open, Premier League Darts, Premier League, and Grand Slam of Darts, Grand Slam. It also runs its own Darts world rankings, world rankings based on players' performances. History Darts had experienced a boom in the 1980s. A number of tournaments were televised on BBC and ITV (TV network), ITV, which allowed the top players to make a full-time living from the sport and turn professional. However, darts steadily dropped from television schedules and by 1989 the only remaining t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throwing Sport
Throwing sports, or throwing games, are physical, human competitions where the outcome is measured by a player's ability to throw an object. The two primary forms are throwing for distance and throwing at a given target or range. The four most prominent throwing for distance sports are in track and field: shot put, discus, javelin, and the hammer throw. Target-based sports have two main genres: bowling and darts, each of which have a great number of variations. History Throwing sports have a long history. Modern track and field comes from a lineage of activities that dates to the Ancient Olympic Games. Artwork from Ancient Greece, in the form of friezes, pottery and statues, attests to the prominence of such sports in the society's physical culture. Bowling games have similarly ancient roots. Games based on throwing stone balls in Ancient Egypt date to 5000 BCE, and a form of bocce is documented in Ancient Rome. The game of catch (throwing and catching an object between pla ...

Cork (material)
Cork is an impermeable buoyant material. It is the phellem layer of bark tissue which is harvested for commercial use primarily from '' Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell. Cork composition varies depending on geographic origin, climate and soil conditions, genetic origin, tree dimensions, age (virgin or reproduction), and growth conditions. However, in general, cork is made up of suberin (average of about 40%), lignin (22%), polysaccharid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sisal
Sisal (, ; ''Agave sisalana'') is a species of flowering plant native to southern Mexico, but widely cultivated and naturalized in many other countries. It yields a stiff fibre used in making rope and various other products. The sisal fiber is traditionally used for rope and twine, and has many other uses, including paper, cloth, footwear, hats, bags, carpets, geotextiles, and dartboards. It is also used as fiber reinforcements for composite fiberglass, rubber, and concrete products. It can also be fermented and distilled to make mezcal. Sisal has an uncertain native origin, but is thought to have originated in the Mexican state of Chiapas. Sisal plants have a lifespan of 7–10 years, producing 200–250 usable leaves containing fibers used in various applications. Sisal is a tropical and subtropical plant, thriving in temperatures above and sunshine. Historically, sisal was used by the Aztecs and Maya for fabric and paper. It spread to other parts of the world in the 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave Americana
''Agave americana'', commonly known as the century plant, maguey, or American aloe, is a flowering plant species belonging to the family Asparagaceae. It is native to Mexico and the United States, specifically Texas. This plant is widely cultivated worldwide for its ornamental value and has become naturalized in various regions, including Southern California, the West Indies, South America, the Mediterranean Basin, Africa, the Canary Islands, India, China, Thailand, and Australia. Despite being called "American aloe" in common parlance, ''Agave americana'' is not a member of the same family as ''Aloe'', although it falls under the same order, Asparagales. Description The common name "century plant" stems from its monocarpic nature of flowering only once at the end of its long life. After flowering, the plant dies but produces adventitious shoots from the base, allowing its growth to continue. Although it is called the century plant, it typically lives only 10 to 30 years. ...

Mathematics Today
Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of abstract objects that consist of either abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to prove properties of objects, a ''proof'' consisting of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crux Mathematicorum
''Crux Mathematicorum'' is a scientific journal of mathematics published by the Canadian Mathematical Society. It contains mathematical problems for secondary school and undergraduate students. Its editor-in-chief is Kseniya Garaschuk. The journal was established in 1975, under the name ''Eureka'', by the Carleton-Ottawa Mathematics Association, with Léo Sauvé as its first editor-in-chief An editor-in-chief (EIC), also known as lead editor or chief editor, is a publication's editorial leader who has final responsibility for its operations and policies. The editor-in-chief heads all departments of the organization and is held accoun .... It took the name ''Crux Mathematicorum'' with its fourth volume, in 1978, to avoid confusion with another journal '' Eureka'' published by the Cambridge University Mathematical Society. The Canadian Mathematical Society took over the journal in 1985, and soon afterwards G.W. (Bill) Sands became its new editor. Bruce L. R. Shawyer took over as e ...

Journal Of The Royal Statistical Society
The ''Journal of the Royal Statistical Society'' is a peer-reviewed scientific journal of statistics. It comprises three series and is published by Oxford University Press for the Royal Statistical Society. History The Statistical Society of London was founded in 1834, but would not begin producing a journal for four years. From 1834 to 1837, members of the society would read the results of their studies to the other members, and some details were recorded in the proceedings. The first study reported to the society in 1834 was a simple survey of the occupations of people in Manchester, England. Conducted by going door-to-door and inquiring, the study revealed that the most common profession was mill-hands, followed closely by weavers. When founded, the membership of the Statistical Society of London overlapped almost completely with the statistical section of the British Association for the Advancement of Science. In 1837 a volume of ''Transactions of the Statistical Society ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factorial
In mathematics, the factorial of a non-negative denoted is the Product (mathematics), product of all positive integers less than or equal The factorial also equals the product of n with the next smaller factorial: \begin n! &= n \times (n-1) \times (n-2) \times (n-3) \times \cdots \times 3 \times 2 \times 1 \\ &= n\times(n-1)!\\ \end For example, 5! = 5\times 4! = 5 \times 4 \times 3 \times 2 \times 1 = 120. The value of 0! is 1, according to the convention for an empty product. Factorials have been discovered in several ancient cultures, notably in Indian mathematics in the canonical works of Jain literature, and by Jewish mystics in the Talmudic book ''Sefer Yetzirah''. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, where its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there In mathematical analysis, factorials are used in power series for the ex ...

Archery Butt
A butt is an archery shooting field, with mounds of earth used for the targets. The name originally referred to the targets themselves, but over time came to mean the platforms that held the targets as well. For instance '' Othello,'' V, ii, 267 mentions "Here is my journey's end, here is my butt". In medieval times, it was compulsory for all yeomen in England to learn archery; see for example An Act concerning shooting in Long Bows, passed in the third year of Henry VIII's reign. Several English towns have districts called "The Butts", but they may not always take their names from archery. The Middle English word "butt" referred to an abutting strip of land, and is often associated with medieval field systems. An example is Newington Butts in south London where contrary to popular belief, the 1955 ''Survey of London'' published by London County Council could find no historical reference to archery butts. It concluded that the name probably derived from the triangle of land bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Bar, Railway Inn, Spofforth, North Yorkshire (1st August 2015) 015
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the ''Öffentlichkeit'' or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, and suffered more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder. Etymology and definitions The name "public" originates with the Latin '' publicus'' (also '' poplicus''), from ''populus'', to the English word ' populace', and in general denotes some mass population ("the ...
