Darts Venues
Darts or dart-throwing is a competitive sport in which two or more players bare-handedly throw small sharp-pointed missiles 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 towards the centre of the board. 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 shooting sport and a traditional pub game. Darts is commonly played in the United Kingdom and the Republic of Ireland, and recreationally enjoyed around the world. History Dartboard The original target in the game is likely to have been a section of a tree trunk, its circular shape and concentric rings giving rise to the standard dartboard patte ...

World Darts Federation
The World Darts Federation (WDF) is a sport governing body and (along with the PDC) a tournament organiser for the game of darts. It was formed in 1974 by representatives of the original fourteen founding members. Membership is open to the national organizing body for darts in all nations. The WDF encourages the promotion of the sport of darts among and between those bodies, in an effort to gain international recognition for darts as a major sport. The WDF is a full member of Global Association of International Sports Federations, which is the governing body for international sports federations. The WDF stages a world championship (called the WDF World Cup), as well as continental championships such as the WDF Americas Cup, the WDF Asia-Pacific Cup and the WDF Europe Cup. The country that is first in the overall leader board (overall best result in the two events, singles, pairs, teams) becomes the world champion. Winners of any of the events can also call themselves the offi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pub Game
A pub game is one which is traditionally played inside or outside a pub or bar. Most pub games date back many years and are rooted in village culture. Many derive from older outdoor sports. Pub games can be loosely grouped into throwing games, dice games, card games, board games, cue and ball games, bat and ball games, coin pushing/throwing games, and drinking games. History In his book, ''Beer and Skittles'', Richard Boston claims that the first regulation concerning national control of pubs was about pub games; Henry VII's statute of 1495 restricted the playing of "indoor games which were distracting Tudor pubmen from archery". Many of pub games owe their origins to older outdoor sports, adapted and transformed over time for indoor play, either for convenience, or to allow publicans to maintain their teams during the off-season. Gaming activities associated with pubs included card games such as cribbage, throwing games such as darts, physical sports such as cricket ...

Cork (material)
Cork is an impermeable buoyant material, the phellem layer of bark tissue that 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%), polysaccharides (cellulose an ... [...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 term sisal may refer either to the plant's common name or the fibre, depending on the context. The sisal fibre 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 fibre reinforcements for composite fibreglass, rubber, and concrete products. Taxonomy The native origin of ''Agave sisalana'' is uncertain. Traditionally, it was deemed to be a native of the Yucatán Peninsula, but no records exist of botanical collections from there. They were originally shipped from the Spanish colonial port of Sisal in Yucatán (thus the name). The Yucatán plantations now cultivate henequen (''Agave fourcroydes''). H.S. Gentry hypothesized a Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave Americana
''Agave americana'', common names century plant, maguey, or American aloe, is a species of flowering plant in the family Asparagaceae, native to Mexico and the United States in Texas. It is cultivated worldwide as an ornamental plant, and has been naturalized in many regions, including parts of the West Indies, South America, Mediterranean Basin, Africa, Canary Islands, India, China, Thailand, and Australia. Despite the common name "American aloe", it is not in the same family as aloe, though it is in the same order, Asparagales. Description Although it is called the century plant, it typically lives only 10 to 30 years. It has a spread around with gray-green leaves of long, each with a prickly margin and a heavy spike at the tip that can pierce deeply. Near the end of its life, the plant sends up a tall, branched stalk, laden with yellow blossoms, that may reach a total height up to . Its common name derives from its semelparous nature of flowering only once at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics TODAY
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of t ...

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. 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 editor in 1996. In 1997 it merged with another journal founded in 1988, ''Mathematical Mayhem'', to become ''Crux Mathematicorum with Mathematical Mayhem''. Jim Totten became editor in 2003, and Václav (Vazz) Linek replaced him in 2008. Ross Honsberger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Wiley 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 of London'' were w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factorial
In mathematics, the factorial of a non-negative denoted is the 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 exponential functi ...

Archery Butts
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 Newington Butts is a former hamlet, now an area of the London Borough of Southwark, that gives its name to a segment of the A3 road running south-west from the Elephant and Castle junction. The road continues as Kennington Park Road leadi ... [...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 p ...
