Instrumental Temperature Record
The instrumental temperature record provides the temperature of Earth's climate system from the historical network of in situ measurements of surface air temperatures and ocean surface temperatures. Data are collected at thousands of meteorological stations, buoys and ships around the globe. The longest-running temperature record is the Central England temperature data series, which starts in 1659. The longest-running quasi-global record starts in 1850. In recent decades, more extensive sampling of ocean temperatures at various depths allows estimates of ocean heat content, but these samples do not form part of the global surface temperature datasets.

Configuration Space
In classical mechanics, the parameters that define the configuration of a system are called generalized coordinates, and the space defined by these coordinates is called the configuration space of the physical system. It is often the case that these parameters satisfy mathematical constraints, such that the set of actual configurations of the system is a manifold in the space of generalized coordinates. This manifold is called the configuration manifold of the system. Notice that this is a notion of "unrestricted" configuration space, i.e. in which different point particles may occupy the same position. In mathematics, in particular in topology, a notion of "restricted" configuration space is mostly used, in which the diagonals, representing "colliding" particles, are removed.

Flat Panel Display
Flat-panel displays are electronic viewing technologies used to enable people to see content (still images, moving images, text, or other visual material) in a range of entertainment, consumer electronics, personal computer, and mobile devices, and many types of medical, transportation and industrial equipment. They are far lighter and thinner than traditional cathode ray tube (CRT) television sets and video displays and are usually less than 10 centimetres (3.9 in) thick. Flat-panel displays can be divided into two display device categories: volatile and static. Volatile displays require that pixels be periodically electronically refreshed to retain their state (e.g., liquid-crystal displays (LCD)). A volatile display only shows an image when it has battery or AC mains power. Static flat-panel displays rely on materials whose color states are bistable (e.g., e-book reader tablets from Sony), and as such, flat-panel displays retain the text or images on the screen even when the power is off. As of 2016, flat-panel displays have almost completely replaced old CRT displays. In many 2010-era applications, specifically small portable devices such as laptops, mobile phones, smartphones, digital cameras, camcorders, point-and-shoot cameras, and pocket video cameras, any display disadvantages of flat-panels (as compared with CRTs) are made up for by portability advantages (thinness and lightweightness). Most 2010s-era flat-panel displays use LCD and/or LED technologies. Most LCD screens are back-lit as color filters are used to display colors. Flat-panel displays are thin and lightweight and provide better linearity and they are capable of higher resolution than typical consumer-grade TVs from earlier eras. The highest resolution for consumer-grade CRT TVs was 1080i; in contrast, many flat-panels can display 1080p or even 4K resolution. As of 2016, some devices that use flat-panels, such as tablet computers, smartphones and, less commonly, laptops, use touchscreens, a feature that enables users to select onscreen icons or trigger actions (e.g., playing a digital video) by touching the screen. Many touchscreen-enabled devices can display a virtual QWERTY or numeric keyboard on the screen, to enable the user to type words or numbers. A multifunctional monitor (MFM) is a flat-panel display that has additional video inputs (more than a typical LCD monitor) and is designed to be used with a variety of external video sources, such as VGA input, HDMI input from a VHS VCR or video game console and, in some cases, a USB input or card reader for viewing digital photos). In many instances, an MFM also includes a TV tuner, making it similar to a LCD TV that offers computer connectivity.

Third World Socialism
Third World socialism was a variant of socialism proponed by Kwame Nkrumah, Modibo Keïta, Ahmed Sékou Touré, Fidel Castro, Julius Nyerere, Salah al-Din al-Bitar, Michel Aflaq, Gamal Abdel Nasser, Juan Perón, Jawaharlal Nehru, Sukarno, David Ben-Gurion, Muammar Gaddafi, Zulfikar Ali Bhutto, Buddhadasa, Walter Lini and other such socialist leaders of the Third World who saw a non-Soviet version of socialism as the answer to a strong and developed nation. It could be argued that the new "turn to the left" leadership in Latin America (see socialism of the 21st century), with its anti-Americanism, connection with less developed Eastern Europe, sense of undeveloped countries/developing countries unity and pro-Arabism/pro-Islamism, is a new kind of Third World socialism. It may be described as an ideologically specific form of Third-Worldism and it is made up of African socialism, Arab socialism, Nasserism, Peronism, Nehruism, Labor Zionism, Islamic socialism,[Note 1] Buddhist socialism and Melanesian socialism.

Panama Papers (Africa)
The Panama Papers are 11.5 million leaked documents that detail financial and attorney–client information for more than 214,488 offshore entities. The documents, some dating back to the 1970s, were created by, and taken from, Panamanian law firm and corporate service provider Mossack Fonseca, and were leaked in 2015 by an anonymous source. This page details related allegations, reactions, and investigations, in Africa. Former South African president Thabo Mbeki, head of the African Union's panel on illicit financial flows, on April 9 called the leak "most welcome" and called on African nations to investigate the citizens of their nations who appear in the papers. His panel's 2015 report found that Africa loses $50 billion a year due to tax evasion and other illicit practices and its 50-year losses top a trillion dollars. Furthermore, he said, the Seychelles, an African nation, is the fourth most mentioned tax haven in the documents.

Levellers
The Levellers were a political movement during the English Civil War (1642–1651) committed to popular sovereignty, extended suffrage, equality before the law and religious tolerance. The hallmark of Leveller thought was its populism, as shown by its emphasis on equal natural rights, and their practice of reaching the public through pamphlets, petitions and vocal appeals to the crowd. The Levellers came to prominence at the end of the First English Civil War (1642–46) and were most influential before the start of the Second Civil War (1648–49). Leveller views and support were found in the populace of the City of London and in some regiments in the New Model Army. Their ideas were presented in their manifesto "Agreement of the People". In contrast to the Diggers, the Levellers opposed common ownership, except in cases of mutual agreement of the property owners. The Levellers were not a political party in the modern sense of the term. They were organised at the national level, with offices in a number of London inns and taverns such as The Rosemary Branch in Islington, which got its name from the sprigs of rosemary that Levellers wore in their hats as a sign of identification. From July 1648 to September 1649, they published a newspaper, The Moderate, and were pioneers in the use of petitions and pamphleteering to political ends. They identified themselves by sea-green ribbons worn on their clothing. After Pride's Purge and the execution of Charles I, power lay in the hands of the Grandees in the Army (and to a lesser extent with the Rump Parliament). The Levellers, along with all other opposition groups, were marginalised by those in power and their influence waned. By 1650, they were no longer a serious threat to the established order.

Mobile Local Search
Mobile local search is a technology that lets people search for local things using mobile equipment such as mobile phones, PDAs, and other mobile devices. Mobile local search satisfies the need to offer a mobile subscriber spontaneous access to near-position services and information such as businesses, products, events, restaurant, movie theatre or other local information. Mobile local search is the search and discovery of persons, places, and things within an identifiable space defined by distinct parameters. These parameters are evolving. Today they include social networks, individuals, cities, neighborhoods, landmarks, and actions that are relevant to the searcher's past, current, and future location. These parameters provide structure to vertically deep and horizontally broad data categories that can stand-alone or are combined to comprise searchable directories. Mobile local search is usually based on organized directories accessed through specialized search tools, rather than the web, although mobile local search often provides links to mobile (WAP) web sites. It is also an application of a location-based service.

Works of Mercy
Works of mercy (sometimes known as acts of mercy) are practices considered meritorious in Christian ethics. The practice is popular in the Catholic Church as an act of both penance and charity. In addition, the Methodist church teaches that the works of mercy are a means of grace which lead to holiness and aid in sanctification. The works of mercy have been traditionally divided into two categories, each with seven elements: Pope John Paul II issued a papal encyclical "Dives in misericordia" on 30 November 1980 declaring that "Jesus Christ taught that man not only receives and experiences the mercy of God, but that he is also called 'to practice mercy' towards others." Another notable devotion associated with the works of mercy is the Divine Mercy, which derives from apparitions of Jesus Christ to Saint Faustina Kowalska.

Multiple Document Interface
A multiple document interface (MDI) is a graphical user interface in which multiple windows reside under a single parent window. Such systems often allow child windows to embed other windows inside them as well, creating complex nested hierarchies. This contrasts with single document interfaces (SDI) where all windows are independent of each other.
