Calc may refer to:
Calculus is the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under and between curves); these two branches are related to each other by the fundamental theorem of calculus. Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit. Generally, modern calculus is considered to have been developed in the 17th century by Isaac Newton and Gottfried Leibniz. Today, calculus has widespread uses in science, engineering and economics and can solve many problems that algebra alone cannot.
Calculus is a part of modern mathematics education. A course in calculus is a gateway to other, more advanced courses in mathematics devoted to the study of functions and limits, broadly called mathematical analysis. Calculus has historically been called "the calculus of infinitesimals", or "infinitesimal calculus". The word "calculus" comes from Latin (calculus) and refers to a small stone used for counting. More generally, calculus (plural calculi) refers to any method or system of calculation guided by the symbolic manipulation of expressions. Some examples of other well-known calculi are propositional calculus, calculus of variations, lambda calculus, and process calculus.
The National Association of Local Councils (NALC) is an association of approximately 9,000 independently elected community, parish and town councils in England. The Head Office of the organisation is at 109 Great Russell Street in Bloomsbury, central London.
The main duties of the NALC include lobbying national government on behalf of its members, and their electorates. The association also provides support, advice and training for member councils, as well as holding an annual conference. The NALC also offers advice and technical guidance to individuals or groups who plan to create new councils for unrepresented communities or areas.
All member councils are represented on one of 38 local county associations of the NALC. It is the county associations who coordinate most of the support offered by the NALC to its members. Every county association then elects one representative from their members, who then sits on the associations National Council. It is the National Council that is largely responsible for representing members to national government.
Old vine (French: vieilles vignes, German: alte Reben), a common description on wine labels, indicates that a wine is the product of grape vines that are notably old. There is a general belief that older vines, when properly handled, will give a better wine. There is no legal or generally agreed definition for old.
Grape vines can grow for over 120 years. After about 20 years vines start to produce smaller crops, and average yields decrease, leading to more concentrated, intense wines. Diseases such as "dead arm" can also afflict old vines, in some cases further concentrating the juice. "Old vines" might apply to an entire estate, or it might mean only a certain parcel planted before others. In the U.S., the most common use is on Zinfandel, because in California vineyards up to 125 years old are still bearing small amounts of prized Zinfandel fruit.
In a place where wine production is longstanding, it often means a wine whose vines are thirty to forty years old. Some wine makers insist the vines should be older than this. In newly established wine regions, twenty years might be old. The definition is further complicated by the fact that certain varieties simply do not have economically viable yields when they get truly ancient.
"Old" is a song recorded by American heavy metal band Machine Head. It was released as a single in two different versions. The title track is taken off of the 1994 album Burn My Eyes. It is the fourth track featured on the band's live album Hellalive, and the ninth track featured on the band's second live album Machine Fucking Head Live.
Old is the third studio album by American hip hop recording artist Danny Brown. The album was released on October 8, 2013, under Fool's Gold Records, and distributed by Alternative Distribution Alliance. The album is Brown's first project to be officially sold through music outlets and digital retailers, whereas his previous projects were self-released for free and made available online.
The album includes production from American, British and Canadian record producers such as A-Trak, BadBadNotGood, Frank Dukes, Oh No, Paul White, Rustie and SKYWLKR, among others. The album also features guest appearances from fellow artists such as Freddie Gibbs, ASAP Rocky, Schoolboy Q, Ab-Soul, Scrufizzer, Charli XCX and Purity Ring.
The album was supported by three singles, "Dip", "25 Bucks" and "Smokin & Drinkin". Upon its release, Old received widespread acclaim from critics. The album debuted at number 17 on the US Billboard 200, selling 15,000 copies in the first week.
Enemy or foe is an individual or a group that is seen as forcefully adverse or threatening. The concept of an enemy has been observed to be "basic for both individuals and communities". The term "enemy" serves the social function of designating a particular entity as a threat, thereby invoking an intense emotional response to that entity. The state of being or having an enemy is enmity, foehood or foeship.
As for the etymology the term enemy is derived from Latin language for 'bad friend' (Latin: inimicus). "Enemy" is a strong word, and "emotions associated with the enemy would include anger, hatred, frustration, envy, jealousy, fear, distrust, and possibly grudging respect". As a political concept, an enemy is likely to be met with hate, violence, battle and war. The opposite of an enemy is a friend or ally. Because the term "the enemy" is a bit bellicose and militaristic to use in polite society, informal substitutes are more often used. Often the substituted terms become pejoratives in the context that they are used. In any case, the designation of an "enemy" exists solely to denote the status of a particular group of people as a threat, and to propagate this designation within the local context. Substituted terms for an enemy often go further to meaningfully identify a known group as an enemy, and to pejoratively frame that identification. A government may seek to represent a person or group as a threat to the public good by designating that person or group to be a public enemy.
