Rosetta (spacecraft)
–
Rosetta was a space probe built by the European Space Agency launched on 2 March 2004. Along with Philae, its lander module, Rosetta performed a study of comet 67P/Churyumov–Gerasimenko. During its journey to the comet, the spacecraft flew by Mars and it was launched as the third cornerstone mission of the ESAs Horizon 2000 programme, after SOHO / Cluster and XMM-Newton. On 6 August 2014, the reached the comet and performed a series of manoeuvres to eventually orbit the comet at distances of 30 to 10 kilometres. On 12 November, its lander module Philae performed the first successful landing on a comet, communications with Philae were briefly restored in June and July 2015, but due to diminishing solar power, Rosettas communications module with the lander was turned off on 27 July 2016. On 30 September 2016, the Rosetta spacecraft ended its mission by hard-landing on the comet in its Maat region, the probe is named after the Rosetta Stone, a stele of Egyptian origin featuring a decree in three scripts. The lander is named after the Philae obelisk, which bears a bilingual Greek and it was one of ESAs Horizon 2000 cornerstone missions. The spacecraft consisted of the Rosetta orbiter, which featured 12 instruments, the Rosetta mission orbited Comet Churyumov–Gerasimenko for 17 months and was designed to complete the most detailed study of a comet ever attempted. The spacecraft was controlled from the European Space Operations Centre, in Darmstadt and it has been estimated that in the decade preceding 2014, some 2,000 people assisted in the mission in some capacity. In 2007, Rosetta made a Mars gravity assist on its way to Comet Churyumov–Gerasimenko, the spacecraft also performed two asteroid flybys. The craft completed its flyby of asteroid 2867 Šteins in September 2008, later, on 20 January 2014, Rosetta was taken out of a 31-month hibernation mode as it approached Comet Churyumov–Gerasimenko. Rosettas Philae lander successfully made the first soft landing on a comet nucleus when it touched down on Comet Churyumov–Gerasimenko on 12 November 2014. On 5 September 2016, ESA announced that the lander was discovered by the narrow-angle camera aboard Rosetta as the made a low,2.7 km pass over the comet. The lander sits on its side wedged into a crevice of the comet. During the 1986 approach of Halleys Comet, international space probes were sent to explore the comet, after the probes returned valuable scientific information, it became obvious that follow-ons were needed that would shed more light on cometary composition and answer new questions. Both ESA and NASA started cooperatively developing new probes, the NASA project was the Comet Rendezvous Asteroid Flyby mission. The ESA project was the follow-on Comet Nucleus Sample Return mission, both missions were to share the Mariner Mark II spacecraft design, thus minimising costs. In 1992, after NASA cancelled CRAF due to budgetary limitations, after the spacecraft launch, Gerhard Schwehm was named mission manager, he retired in March 2014

Rosetta Stone
–
The Rosetta Stone is a granodiorite stele, found in 1799, inscribed with three versions of a decree issued at Memphis, Egypt in 196 BC during the Ptolemaic dynasty on behalf of King Ptolemy V. The top and middle texts are in Ancient Egyptian using hieroglyphic script and Demotic script, respectively, as the decree is the same in all three versions, the Rosetta Stone proved to be the key to deciphering Egyptian hieroglyphs. The stone, carved in black granodiorite during the Hellenistic period, is believed to have originally been displayed within a temple, possibly at nearby Sais. It was probably moved during the early Christian or medieval period and it was rediscovered there in July 1799 by a French soldier named Pierre-François Bouchard during the Napoleonic campaign in Egypt. Lithographic copies and plaster casts began circulating among European museums and scholars, meanwhile, British troops defeated the French in Egypt in 1801, and the original stone came into British possession under the Capitulation of Alexandria and was transported to London. It has been on display at the British Museum almost continuously since 1802. It is the object in the British Museum. Study of the decree was already under way when the first full translation of the Greek text appeared in 1803, the Rosetta Stone is, therefore, no longer unique, but it was the essential key to modern understanding of Ancient Egyptian literature and civilisation. The term Rosetta Stone is now used in contexts as the name for the essential clue to a new field of knowledge. The Rosetta Stone is listed as a stone of black granite, found at Rosetta in a contemporary catalogue of the artefacts discovered by the French expedition and surrendered to British troops in 1801. This gave a dark colour to the stone that led to its identification as black basalt. The Rosetta Stone is 1,123 millimetres high at its highest point,757 mm wide and it bears three inscriptions, the top register in Ancient Egyptian hieroglyphs, the second in the Egyptian Demotic script, and the third in Ancient Greek. The Rosetta Stone is a fragment of a larger stele, no additional fragments were found in later searches of the Rosetta site. Owing to its state, none of the three texts is absolutely complete. The top register, composed of Egyptian hieroglyphs, suffered the most damage, only the last 14 lines of the hieroglyphic text can be seen, all of them are broken on the right side, and 12 of them on the left. The following register of demotic text has survived best, it has 32 lines, the final register of Greek text contains 54 lines, of which the first 27 survive in full, the rest are increasingly fragmentary due to a diagonal break at the bottom right of the stone. The stele was erected after the coronation of King Ptolemy V and was inscribed with a decree established the divine cult of the new ruler. The decree was issued by a congress of priests who gathered at Memphis, the date is given as 4 Xandicus in the Macedonian calendar and 18 Meshir in the Egyptian calendar, which corresponds to March 27,196 BC

Timeline of the far future
–
While predictions of the future can never be absolutely certain, present understanding in various fields allows for the prediction of far-future events, if only in the broadest outline. Stars will eventually exhaust their supply of fuel and burn out. Close encounters gravitationally fling planets from their systems, and star systems from galaxies. Eventually, matter itself is expected to come under the influence of radioactive decay, the timelines displayed here cover events from the beginning of the 11th millennium to the furthest reaches of future time. To date five spacecraft are on trajectories which will take out of the Solar System.

Long Now Foundation
–
The Long Now Foundation, established in 1996, is a public, non-profit organization based in San Francisco that seeks to become the seed of a very long-term cultural institution. It aims to provide a counterpoint to what it views as todays faster/cheaper mindset, the Long Now Foundation hopes to creatively foster responsibility in the framework of the next 10,000 years, and so uses 5-digit dates to address the Year 10,000 problem. The organisations logo, a capital X with an overline, is a representation of 10,000 in Roman numerals, the purpose of the Clock of the Long Now is to construct a timepiece that will operate with minimum human intervention for ten millennia. Its power source should be renewable but similarly unlootable, a prototype of a potential final clock candidate was activated on December 31,1999, and is currently on display at the Science Museum at London. The Foundation hopes to construct the finished Clock at Mount Washington south of Great Basin National Park near Ely, the Rosetta Project is an effort to preserve all languages that have a high likelihood of extinction over the period from 2000 to 2100. These include many languages whose native speakers number in the thousands or fewer, other languages with many more speakers are considered by the project to be endangered because of the increasing importance of English as an international language of commerce and culture. Samples of such languages are to be inscribed onto a disc of nickel alloy three inches across, a Version 1.0 of the disc was completed on November 3,2008. The Long Bet Project was created by the Long Now Foundation to propose and keep track of bets on long-term events, the Long Now Foundation describes The Long Bet Project as a public arena for enjoyably competitive predictions, of interest to society, with philanthropic money at stake. One example bet would be on whether people will fly on pilotless aircraft by 2030. Bets that were resolved in 2010 included predictions about peak oil, print on demand, modem obsolescence, in November 2003, the Long Now Foundation began a series of monthly Seminars About Long-term Thinking with a lecture by Brian Eno. The seminars are held in the San Francisco Bay Area and have focused on policy and thinking, scenario planning, singularity. The seminars are available for download in various formats from the Long Now Foundation and they are intended to nudge civilization toward making long-term thinking automatic and common. As part of the Seminar series, there are debates on areas of long term concern. The point of Long Now debates is not win-lose, the point is public clarity and deep understanding, leading to action graced with nuance and built-in adaptivity, with long-term responsibility in mind. In operation, There are two debaters, Alice and Bob, Alice takes the podium, makes her argument. Then Bob takes her place, but before he can present his counter-argument, he must summarize Alice’s argument to her satisfaction — a demonstration of respect and good faith. Only when Alice agrees that Bob has got it right is he permitted to proceed with his own argument — and then, mutual understanding is enforced by a reciprocal requirement to describe the others argument to their satisfaction, with the goal being more understanding after the event than there was beforehand. Opened in June 2014, The Interval was designed as social space in the foundations Fort Mason facility in San Francisco

Language
–
Language is the ability to acquire and use complex systems of communication, particularly the human ability to do so, and a language is any specific example of such a system. The scientific study of language is called linguistics, questions concerning the philosophy of language, such as whether words can represent experience, have been debated since Gorgias and Plato in Ancient Greece. Thinkers such as Rousseau have argued that language originated from emotions while others like Kant have held that it originated from rational and logical thought, 20th-century philosophers such as Wittgenstein argued that philosophy is really the study of language. Major figures in linguistics include Ferdinand de Saussure and Noam Chomsky, estimates of the number of languages in the world vary between 5,000 and 7,000. However, any precise estimate depends on an arbitrary distinction between languages and dialects. Natural languages are spoken or signed, but any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, in whistling, signed and this is because human language is modality-independent. All languages rely on the process of semiosis to relate signs to particular meanings, human language has the properties of productivity and displacement, and relies entirely on social convention and learning. Its complex structure affords a wider range of expressions than any known system of animal communication. Language is processed in different locations in the human brain. Humans acquire language through interaction in early childhood, and children generally speak fluently when they are approximately three years old. The use of language is deeply entrenched in human culture, a group of languages that descend from a common ancestor is known as a language family. The languages of the Dravidian family that are mostly in Southern India include Tamil. Academic consensus holds that between 50% and 90% of languages spoken at the beginning of the 21st century will probably have become extinct by the year 2100. The English word language derives ultimately from Proto-Indo-European *dn̥ǵʰwéh₂s tongue, speech, language through Latin lingua, language, tongue, and Old French language. The word is used to refer to codes, ciphers. Unlike conventional human languages, a language in this sense is a system of signs for encoding and decoding information. This article specifically concerns the properties of human language as it is studied in the discipline of linguistics. As an object of study, language has two primary meanings, an abstract concept, and a specific linguistic system, e. g. French

Globalization
–
Globalization or globalisation is the action or procedure of international integration arising from the interchange of world views, products, ideas, and other aspects of culture. Advances in transportation and in telecommunications infrastructure have been factors in globalization, generating further interdependence of economic. Large-scale globalization began in the 1820s, in the late 19th century and early 20th century, the connectivity of the worlds economies and cultures grew very quickly. The term globalization is recent, only establishing its current meaning in the 1970s, further, environmental challenges such as global warming, cross-boundary water and air pollution, and overfishing of the ocean are linked with globalization. Globalizing processes affect and are affected by business and work organization, economics, socio-cultural resources, academic literature commonly subdivides globalization into three major areas, economic globalization, cultural globalization, and political globalization. The term globalization is derived from the word globalize, which refers to the emergence of a network of economic systems. One of the earliest known usages of the term as a noun was in a 1930 publication entitled Towards New Education, a related term, corporate giants, was coined by Charles Taze Russell in 1897 to refer to the largely national trusts and other large enterprises of the time. By the 1960s, both began to be used as synonyms by economists and other social scientists. Economist Theodore Levitt is widely credited with coining the term in an article entitled Globalization of Markets, However, the term globalization was in use well before this and had been used by other scholars as early as 1981. Levitt can be credited with popularizing the term and bringing it into the mainstream audience in the later half of the 1980s. Due to the complexity of the concept, research projects, articles, sociologists Martin Albrow and Elizabeth King define globalization as all those processes by which the people of the world are incorporated into a single world society. Globalization can be located on a continuum with the local, national and regional, without reference to such expansive spatial connections, there can be no clear or coherent formulation of this term. A satisfactory definition of globalization must capture each of these elements, extensity, intensity, velocity and it pertains to the increasing ease with which somebody on one side of the world can interact, to mutual benefit, with somebody on the other side of the world. The ideological dimension, according to Steger, is filled with a range of norms, claims, beliefs and they have also argued that four different forms of globalization can be distinguished that complement and cut across the solely empirical dimensions. According to James, the oldest dominant form of globalization is embodied globalization, a second form is agency-extended globalization, the circulation of agents of different institutions, organizations, and polities, including imperial agents. Object-extended globalization, a form, is the movement of commodities. He calls the transmission of ideas, images, knowledge, and information across world-space disembodied globalization and he asserted that the pace of globalization was quickening and that its impact on business organization and practice would continue to grow. Economist Takis Fotopoulos defined economic globalization as the opening and deregulation of commodity, capital and he used political globalization to refer to the emergence of a transnational elite and a phasing out of the nation-state

English language

English /ˈɪŋɡlɪʃ/ is a West Germanic language that was first spoken in early medieval England and is now the global lingua franca. Named after the Angles, one of the Germanic tribes that migrated to England, English is either the official language or one of the official languages in almost 60 sovereign states. It is the third most common language in the world, after Mandarin. It is the most widely learned second language and a language of the United Nations, of the European Union. It is the most widely spoken Germanic language, accounting for at least 70% of speakers of this Indo-European branch, English has developed over the course of more than 1,400 years. The earliest forms of English, a set of Anglo-Frisian dialects brought to Great Britain by Anglo-Saxon settlers in the century, are called Old English. Middle English began in the late 11th century with the Norman conquest of England, Early Modern English began in the late 15th century with the introduction of the printing press to London and the King James Bible, and the start of the Great Vowel Shift. Through the worldwide influence of the British Empire, modern English spread around the world from the 17th to mid-20th centuries, English is an Indo-European language, and belongs to the West Germanic group of the Germanic languages. Most closely related to English are the Frisian languages, and English, Old Saxon and its descendent Low German languages are also closely related, and sometimes Low German, English, and Frisian are grouped together as the Ingvaeonic or North Sea Germanic languages. Modern English descends from Middle English, which in turn descends from Old English, particular dialects of Old and Middle English also developed into a number of other English languages, including Scots and the extinct Fingallian and Forth and Bargy dialects of Ireland. English is classified as a Germanic language because it shares new language features with other Germanic languages such as Dutch, German and these shared innovations show that the languages have descended from a single common ancestor, which linguists call Proto-Germanic. Through Grimms law, the word for foot begins with /f/ in Germanic languages, English is classified as an Anglo-Frisian language because Frisian and English share other features, such as the palatalisation of consonants that were velar consonants in Proto-Germanic. The earliest form of English is called Old English or Anglo-Saxon, in the fifth century, the Anglo-Saxons settled Britain and the Romans withdrew from Britain. England and English are named after the Angles, Old English was divided into four dialects, the Anglian dialects, Mercian and Northumbrian, and the Saxon dialects, Kentish and West Saxon. Through the educational reforms of King Alfred in the century and the influence of the kingdom of Wessex. The epic poem Beowulf is written in West Saxon, and the earliest English poem, Modern English developed mainly from Mercian, but the Scots language developed from Northumbrian. A few short inscriptions from the period of Old English were written using a runic script. By the sixth century, a Latin alphabet was adopted, written with half-uncial letterforms and it included the runic letters wynn ⟨ƿ⟩ and thorn ⟨þ⟩, and the modified Latin letters eth ⟨ð⟩, and ash ⟨æ⟩

Oxford English Dictionary

The Oxford English Dictionary is a descriptive dictionary of the English language, published by the Oxford University Press. The second edition came to 21,728 pages in 20 volumes, in 1895, the title The Oxford English Dictionary was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in ten bound volumes. In 1933, the title The Oxford English Dictionary fully replaced the name in all occurrences in its reprinting as twelve volumes with a one-volume supplement. More supplements came over the years until 1989, when the edition was published. Since 2000, an edition of the dictionary has been underway. The first electronic version of the dictionary was available in 1988. The online version has been available since 2000, and as of April 2014 was receiving two million hits per month. The third edition of the dictionary will probably appear in electronic form, Nigel Portwood, chief executive of Oxford University Press. As a historical dictionary, the Oxford English Dictionary explains words by showing their development rather than merely their present-day usages, therefore, it shows definitions in the order that the sense of the word began being used, including word meanings which are no longer used. The format of the OEDs entries has influenced numerous other historical lexicography projects and this influenced later volumes of this and other lexicographical works. As of 30 November 2005, the Oxford English Dictionary contained approximately 301,100 main entries, the dictionarys latest, complete print edition was printed in 20 volumes, comprising 291,500 entries in 21,730 pages. The longest entry in the OED2 was for the verb set, as entries began to be revised for the OED3 in sequence starting from M, the longest entry became make in 2000, then put in 2007, then run in 2011. Despite its impressive size, the OED is neither the worlds largest nor the earliest exhaustive dictionary of a language, the Dutch dictionary Woordenboek der Nederlandsche Taal is the worlds largest dictionary, has similar aims to the OED and took twice as long to complete. Another earlier large dictionary is the Grimm brothers dictionary of the German language, begun in 1838, the official dictionary of Spanish is the Diccionario de la lengua española, and its first edition was published in 1780. The Kangxi dictionary of Chinese was published in 1716, trench suggested that a new, truly comprehensive dictionary was needed. On 7 January 1858, the Society formally adopted the idea of a new dictionary. Volunteer readers would be assigned particular books, copying passages illustrating word usage onto quotation slips, later the same year, the Society agreed to the project in principle, with the title A New English Dictionary on Historical Principles. He withdrew and Herbert Coleridge became the first editor, on 12 May 1860, Coleridges dictionary plan was published and research was started

Nickel
–
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a golden tinge. Nickel belongs to the metals and is hard and ductile. Meteoric nickel is found in combination with iron, a reflection of the origin of elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earths inner core, use of nickel has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an element in 1751 by Axel Fredrik Cronstedt. The elements name comes from a mischievous sprite of German miner mythology, Nickel, an economically important source of nickel is the iron ore limonite, which often contains 1–2% nickel. Nickels other important ore minerals include garnierite, and pentlandite, major production sites include the Sudbury region in Canada, New Caledonia in the Pacific, and Norilsk in Russia. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant, historically, it has been used for plating iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver. About 6% of world production is still used for corrosion-resistant pure-nickel plating. Nickel-plated objects sometimes provoke nickel allergy, Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements that are ferromagnetic around room temperature, alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is valuable in modern times chiefly in alloys, about 60% of world production is used in nickel-steels, other common alloys and some new superalloys comprise most of the remainder of world nickel use, with chemical uses for nickel compounds consuming less than 3% of production. As a compound, nickel has a number of chemical manufacturing uses. Nickel is a nutrient for some microorganisms and plants that have enzymes with nickel as an active site. Nickel is a metal with a slight golden tinge that takes a high polish. It is one of four elements that are magnetic at or near room temperature. Its Curie temperature is 355 °C, meaning that bulk nickel is non-magnetic above this temperature, the unit cell of nickel is a face-centered cube with the lattice parameter of 0.352 nm, giving an atomic radius of 0.124 nm

Alloy
–
An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character, an alloy may be a solid solution of metal elements or a mixture of metallic phases. Intermetallic compounds are alloys with a stoichiometry and crystal structure. Zintl phases are sometimes considered alloys depending on bond types. Alloys are used in a variety of applications. In some cases, a combination of metals may reduce the overall cost of the material while preserving important properties, in other cases, the combination of metals imparts synergistic properties to the constituent metal elements such as corrosion resistance or mechanical strength. Examples of alloys are steel, solder, brass, pewter, duralumin, bronze, the alloy constituents are usually measured by mass. Alloys are usually classified as substitutional or interstitial alloys, depending on the arrangement that forms the alloy. They can be classified as homogeneous, or heterogeneous or intermetallic. An alloy is a mixture of elements, which forms an impure substance that retains the characteristics of a metal. Alloys are made by mixing two or more elements, at least one of which is a metal and this is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the base, they will be soluble. The mechanical properties of alloys will often be different from those of its individual constituents. A metal that is very soft, such as aluminium, can be altered by alloying it with another soft metal. Although both metals are soft and ductile, the resulting aluminium alloy will have much greater strength. Adding a small amount of carbon to iron trades its great ductility for the greater strength of an alloy called steel. Due to its strength, but still substantial toughness, and its ability to be greatly altered by heat treatment, steel is one of the most useful. By adding chromium to steel, its resistance to corrosion can be enhanced, creating stainless steel, while adding silicon will alter its electrical characteristics, producing silicon steel

Open source
–
The open-source model is a decentralized development model that encourages open collaboration. A main principle of open-source software development is peer production, with such as source code, blueprints. The open-source movement in software began as a response to the limitations of proprietary code, the model is used for projects such as in open-source appropriate technologies, and open-source drug discovery. Open source promotes universal access via an open-source or free license to a design or blueprint. Before the phrase open source became widely adopted, developers and producers used a variety of other terms, Open source gained hold with the rise of the Internet. The open-source software movement arose to clarify copyright, licensing, domain, generally, open source refers to a computer program in which the source code is available to the general public for use and/or modification from its original design. Open-source code is meant to be an effort, where programmers improve upon the source code. Code is released under the terms of a software license, depending on the license terms, others may then download, modify, and publish their version back to the community. The sharing of technical information predates the Internet and the personal computer considerably, for instance, in the early years of automobile development a group of capital monopolists owned the rights to a 2-cycle gasoline engine patent originally filed by George B. By controlling this patent, they were able to monopolize the industry and force car manufacturers to adhere to their demands, in 1911, independent automaker Henry Ford won a challenge to the Selden patent. The result was that the Selden patent became virtually worthless and a new association was formed, by the time the US entered World War II,92 Ford patents and 515 patents from other companies were being shared among these manufacturers, without any exchange of money. Beginning in the 1960s, ARPANET researchers used an open Request for Comments process to encourage feedback in early telecommunication network protocols and this led to the birth of the early Internet in 1969. The sharing of code on the Internet began when the Internet was relatively primitive, with software distributed via UUCP, Usenet, IRC. BSD, for example, was first widely distributed by posts to comp. os. linux on the Usenet, in addition, the ambiguity of the term free software was seen as discouraging business adoption. The group included Christine Peterson, Todd Anderson, Larry Augustin, Jon Hall, Sam Ockman, Michael Tiemann, Peterson suggested open source at a meeting held at Palo Alto, California, in reaction to Netscapes announcement in January 1998 of a source code release for Navigator. Linus Torvalds gave his support the day, and Phil Hughes backed the term in Linux Journal. Richard Stallman, the founder of the free movement, initially seemed to adopt the term. Netscape released its code under the Netscape Public License and later under the Mozilla Public License

Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17,1991 by Linus Torvalds, the Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. Linux was originally developed for computers based on the Intel x86 architecture. Because of the dominance of Android on smartphones, Linux has the largest installed base of all operating systems. Linux is also the operating system on servers and other big iron systems such as mainframe computers. It is used by around 2. 3% of desktop computers, the Chromebook, which runs on Chrome OS, dominates the US K–12 education market and represents nearly 20% of the sub-$300 notebook sales in the US. Linux also runs on embedded systems – devices whose operating system is built into the firmware and is highly tailored to the system. This includes TiVo and similar DVR devices, network routers, facility automation controls, televisions, many smartphones and tablet computers run Android and other Linux derivatives. The development of Linux is one of the most prominent examples of free, the underlying source code may be used, modified and distributed—commercially or non-commercially—by anyone under the terms of its respective licenses, such as the GNU General Public License. Typically, Linux is packaged in a known as a Linux distribution for both desktop and server use. Distributions intended to run on servers may omit all graphical environments from the standard install, because Linux is freely redistributable, anyone may create a distribution for any intended use. The Unix operating system was conceived and implemented in 1969 at AT&Ts Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, first released in 1971, Unix was written entirely in assembly language, as was common practice at the time. Later, in a key pioneering approach in 1973, it was rewritten in the C programming language by Dennis Ritchie, the availability of a high-level language implementation of Unix made its porting to different computer platforms easier. Due to an earlier antitrust case forbidding it from entering the computer business, as a result, Unix grew quickly and became widely adopted by academic institutions and businesses. In 1984, AT&T divested itself of Bell Labs, freed of the legal obligation requiring free licensing, the GNU Project, started in 1983 by Richard Stallman, has the goal of creating a complete Unix-compatible software system composed entirely of free software. Later, in 1985, Stallman started the Free Software Foundation, by the early 1990s, many of the programs required in an operating system were completed, although low-level elements such as device drivers, daemons, and the kernel were stalled and incomplete. Linus Torvalds has stated that if the GNU kernel had been available at the time, although not released until 1992 due to legal complications, development of 386BSD, from which NetBSD, OpenBSD and FreeBSD descended, predated that of Linux. Torvalds has also stated that if 386BSD had been available at the time, although the complete source code of MINIX was freely available, the licensing terms prevented it from being free software until the licensing changed in April 2000

Linguistics
–
Linguistics is the scientific study of language, and involves an analysis of language form, language meaning, and language in context. Linguists traditionally analyse human language by observing an interplay between sound and meaning, phonetics is the study of speech and non-speech sounds, and delves into their acoustic and articulatory properties. While the study of semantics typically concerns itself with truth conditions, Grammar is a system of rules which governs the production and use of utterances in a given language. These rules apply to sound as well as meaning, and include componential sub-sets of rules, such as those pertaining to phonology, morphology, modern theories that deal with the principles of grammar are largely based within Noam Chomskys ideological school of generative grammar. In the early 20th century, Ferdinand de Saussure distinguished between the notions of langue and parole in his formulation of structural linguistics. According to him, parole is the utterance of speech, whereas langue refers to an abstract phenomenon that theoretically defines the principles. This distinction resembles the one made by Noam Chomsky between competence and performance in his theory of transformative or generative grammar. According to Chomsky, competence is an innate capacity and potential for language, while performance is the specific way in which it is used by individuals, groups. The study of parole is the domain of sociolinguistics, the sub-discipline that comprises the study of a system of linguistic facets within a certain speech community. Discourse analysis further examines the structure of texts and conversations emerging out of a speech communitys usage of language, Stylistics also involves the study of written, signed, or spoken discourse through varying speech communities, genres, and editorial or narrative formats in the mass media. In the 1960s, Jacques Derrida, for instance, further distinguished between speech and writing, by proposing that language be studied as a linguistic medium of communication in itself. Palaeography is therefore the discipline that studies the evolution of scripts in language. Linguistics also deals with the social, cultural, historical and political factors that influence language, through which linguistic, research on language through the sub-branches of historical and evolutionary linguistics also focus on how languages change and grow, particularly over an extended period of time. Language documentation combines anthropological inquiry with linguistic inquiry, in order to describe languages, lexicography involves the documentation of words that form a vocabulary. Such a documentation of a vocabulary from a particular language is usually compiled in a dictionary. Computational linguistics is concerned with the statistical or rule-based modeling of natural language from a computational perspective, specific knowledge of language is applied by speakers during the act of translation and interpretation, as well as in language education – the teaching of a second or foreign language. Policy makers work with governments to implement new plans in education, related areas of study also includes the disciplines of semiotics, literary criticism, translation, and speech-language pathology. Before the 20th century, the philology, first attested in 1716, was commonly used to refer to the science of language

Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California, adjacent to Palo Alto and between San Jose and San Francisco. Its 8, 180-acre campus is one of the largest in the United States, Stanford also has land and facilities elsewhere. The university was founded in 1885 by Leland and Jane Stanford in memory of their only child, Stanford was a former Governor of California and U. S. Senator, he made his fortune as a railroad tycoon. The school admitted its first students 125 years ago on October 1,1891, Stanford University struggled financially after Leland Stanfords death in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, Provost Frederick Terman supported faculty and graduates entrepreneurialism to build self-sufficient local industry in what would later be known as Silicon Valley. The university is one of the top fundraising institutions in the country. There are three schools that have both undergraduate and graduate students and another four professional schools. Students compete in 36 varsity sports, and the university is one of two institutions in the Division I FBS Pac-12 Conference. Stanford faculty and alumni have founded a number of companies that produce more than $2.7 trillion in annual revenue. It is the alma mater of 30 living billionaires,17 astronauts and it is also one of the leading producers of members of the United States Congress. Sixty Nobel laureates and seven Fields Medalists have been affiliated with Stanford as students, alumni, Stanford University was founded in 1885 by Leland and Jane Stanford, dedicated to Leland Stanford Jr, their only child. The institution opened in 1891 on Stanfords previous Palo Alto farm, despite being impacted by earthquakes in both 1906 and 1989, the campus was rebuilt each time. In 1919, The Hoover Institution on War, Revolution and Peace was started by Herbert Hoover to preserve artifacts related to World War I, the Stanford Medical Center, completed in 1959, is a teaching hospital with over 800 beds. The SLAC National Accelerator Laboratory, which was established in 1962, in 2008, 60% of this land remained undeveloped. Besides the central campus described below, the university also operates at more remote locations, some elsewhere on the main campus. Stanfords main campus includes a place within unincorporated Santa Clara County. The campus also includes land in unincorporated San Mateo County, as well as in the city limits of Menlo Park, Woodside. The academic central campus is adjacent to Palo Alto, bounded by El Camino Real, Stanford Avenue, Junipero Serra Boulevard, the United States Postal Service has assigned it two ZIP codes,94305 for campus mail and 94309 for P. O. box mail

Yale University

Yale University is an American private Ivy League research university in New Haven, Connecticut. Founded in 1701 in Saybrook Colony to train Congregationalist ministers, it is the third-oldest institution of education in the United States. The Collegiate School moved to New Haven in 1716, and shortly after was renamed Yale College in recognition of a gift from British East India Company governor Elihu Yale. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century the school introduced graduate and professional instruction, awarding the first Ph. D. in the United States in 1861 and organizing as a university in 1887. Yale is organized into fourteen constituent schools, the undergraduate college, the Yale Graduate School of Arts and Sciences. While the university is governed by the Yale Corporation, each schools faculty oversees its curriculum, the universitys assets include an endowment valued at $25.4 billion as of June 2016, the second largest of any U. S. educational institution. The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States, Yale College undergraduates follow a liberal arts curriculum with departmental majors and are organized into a social system of residential colleges. Almost all faculty teach courses, more than 2,000 of which are offered annually. Students compete intercollegiately as the Yale Bulldogs in the NCAA Division I – Ivy League, Yale has graduated many notable alumni, including five U. S. Presidents,19 U. S. Supreme Court Justices,20 living billionaires, and many heads of state. In addition, Yale has graduated hundreds of members of Congress,57 Nobel laureates,5 Fields Medalists,247 Rhodes Scholars, and 119 Marshall Scholars have been affiliated with the University. Yale traces its beginnings to An Act for Liberty to Erect a Collegiate School, passed by the General Court of the Colony of Connecticut on October 9,1701, the Act was an effort to create an institution to train ministers and lay leadership for Connecticut. Soon thereafter, a group of ten Congregationalist ministers, Samuel Andrew, Thomas Buckingham, Israel Chauncy, Samuel Mather, the group, led by James Pierpont, is now known as The Founders. Originally known as the Collegiate School, the institution opened in the home of its first rector, Abraham Pierson, the school moved to Saybrook, and then Wethersfield. In 1716 the college moved to New Haven, Connecticut, the feud caused the Mathers to champion the success of the Collegiate School in the hope that it would maintain the Puritan religious orthodoxy in a way that Harvard had not. Cotton Mather suggested that the school change its name to Yale College, meanwhile, a Harvard graduate working in England convinced some 180 prominent intellectuals that they should donate books to Yale. The 1714 shipment of 500 books represented the best of modern English literature, science, philosophy and it had a profound effect on intellectuals at Yale. Undergraduate Jonathan Edwards discovered John Lockes works and developed his original theology known as the new divinity

The University of California, Berkeley, is a public research university located in Berkeley, California. In 1960s, UC Berkeley was particularly noted for the Free Speech Movement as well as the Anti-Vietnam War Movement led by its students. S, Department of Energy, and is home to many world-renowned research institutes and organizations including Mathematical Sciences Research Institute and Space Sciences Laboratory. Faculty member J. R. Oppenheimer, the father of the atomic bomb, Lawrence Livermore Lab also discovered or co-discovered six chemical elements. The Academic Ranking of World Universities also ranks the University of California, Berkeley, third in the world overall, in 1866, the private College of California purchased the land comprising the current Berkeley campus. Ten faculty members and almost 40 students made up the new University of California when it opened in Oakland in 1869, billings was a trustee of the College of California and suggested that the college be named in honor of the Anglo-Irish philosopher George Berkeley. In 1870, Henry Durant, the founder of the College of California, with the completion of North and South Halls in 1873, the university relocated to its Berkeley location with 167 male and 22 female students and held its first classes. In 1905, the University Farm was established near Sacramento, ultimately becoming the University of California, by the 1920s, the number of campus buildings had grown substantially, and included twenty structures designed by architect John Galen Howard. Robert Gordon Sproul served as president from 1930 to 1958, by 1942, the American Council on Education ranked UC Berkeley second only to Harvard University in the number of distinguished departments. During World War II, following Glenn Seaborgs then-secret discovery of plutonium, UC Berkeley physics professor J. Robert Oppenheimer was named scientific head of the Manhattan Project in 1942. Along with the Lawrence Berkeley National Laboratory, Berkeley is now a partner in managing two other labs, Los Alamos National Laboratory and Lawrence Livermore National Laboratory, originally, military training was compulsory for male undergraduates, and Berkeley housed an armory for that purpose. In 1917, Berkeleys ROTC program was established, and its School of Military Aeronautics trained future pilots, including Jimmy Doolittle, both Robert McNamara and Frederick C. Weyand graduated from UC Berkeleys ROTC program, earning B. A. degrees in 1937 and 1938, in 1926, future fleet admiral Chester W. Nimitz established the first Naval Reserve Officers Training Corps unit at Berkeley. The Board of Regents ended compulsory military training at Berkeley in 1962, during the McCarthy era in 1949, the Board of Regents adopted an anti-communist loyalty oath. A number of faculty members objected and were dismissed, ten years passed before they were reinstated with back pay, in 1952, the University of California became an entity separate from the Berkeley campus. Each campus was given autonomy and its own Chancellor. Then-president Sproul assumed presidency of the entire University of California system, Berkeley gained a reputation for student activism in the 1960s with the Free Speech Movement of 1964 and opposition to the Vietnam War. In the highly publicized Peoples Park protest in 1969, students and the school conflicted over use of a plot of land, then governor of California Ronald Reagan called the Berkeley campus a haven for communist sympathizers, protesters, and sex deviants. Modern students at Berkeley are less active, with a greater percentage of moderates and conservatives

Library of Congress
–
The Library of Congress is the research library that officially serves the United States Congress and is the de facto national library of the United States. It is the oldest federal cultural institution in the United States, the Library is housed in three buildings on Capitol Hill in Washington, D. C. it also maintains the Packard Campus in Culpeper, Virginia, which houses the National Audio-Visual Conservation Center. The Library of Congress claims to be the largest library in the world and its collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 450 languages. Two-thirds of the books it acquires each year are in other than English. The Library of Congress moved to Washington in 1800, after sitting for years in the temporary national capitals of New York. John J. Beckley, who became the first Librarian of Congress, was two dollars per day and was required to also serve as the Clerk of the House of Representatives. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s, most of the original collection had been destroyed by the British in 1814, during the War of 1812. To restore its collection in 1815, the bought from former president Thomas Jefferson his entire personal collection of 6,487 books. After a period of growth, another fire struck the Library in its Capitol chambers in 1851, again destroying a large amount of the collection. The Library received the right of transference of all copyrighted works to have two copies deposited of books, maps, illustrations and diagrams printed in the United States. It also began to build its collections of British and other European works and it included several stories built underground of steel and cast iron stacks. Although the Library is open to the public, only high-ranking government officials may check out books, the Library promotes literacy and American literature through projects such as the American Folklife Center, American Memory, Center for the Book, and Poet Laureate. James Madison is credited with the idea for creating a congressional library, part of the legislation appropriated $5,000 for the purchase of such books as may be necessary for the use of Congress. And for fitting up an apartment for containing them. Books were ordered from London and the collection, consisting of 740 books and 3 maps, was housed in the new Capitol, as president, Thomas Jefferson played an important role in establishing the structure of the Library of Congress. The new law also extended to the president and vice president the ability to borrow books and these volumes had been left in the Senate wing of the Capitol. One of the only congressional volumes to have survived was a government account book of receipts and it was taken as a souvenir by a British Commander whose family later returned it to the United States government in 1940. Within a month, former president Jefferson offered to sell his library as a replacement

Dallas is a major city in the U. S. state of Texas. It is the most populous city in the Dallas–Fort Worth metroplex, the citys population ranks ninth in the U. S. and third in Texas after Houston and San Antonio. The citys prominence arose from its importance as a center for the oil and cotton industries. The bulk of the city is in Dallas County, of which it is the county seat, however, sections of the city are located in Collin, Denton, Kaufman, and Rockwall counties. According to the 2010 United States Census, the city had a population of 1,197,816, the United States Census Bureaus estimate for the citys population increased to 1,300,092 as of July 1,2015. In 2016 DFW ascended to the one spot in the nation in year-over-year population growth. In 2014, the metropolitan economy surpassed Washington, D. C. to become the fifth largest in the U. S. with a 2014 real GDP over $504 billion, as such, the metropolitan areas economy is the 10th largest in the world. As of January 2017, the job count has increased to 3,558,200 jobs. The citys economy is based on banking, commerce, telecommunications, technology, energy, healthcare and medical research. The city is home to the third-largest concentration of Fortune 500 companies in the nation. Located in North Texas, Dallas is the core of the largest metropolitan area in the South. Dallas and nearby Fort Worth were developed due to the construction of railroad lines through the area allowing access to cotton, cattle. Later, France also claimed the area but never established much settlement, the area remained under Spanish rule until 1821, when Mexico declared independence from Spain, and the area was considered part of the Mexican state of Coahuila y Tejas. In 1836, the Republic of Texas, with majority Anglo-American settlers, in 1839, Warren Angus Ferris surveyed the area around present-day Dallas. John Neely Bryan established a permanent settlement near the Trinity River named Dallas in 1841, the origin of the name is uncertain. The Republic of Texas was annexed by the United States in 1845, Dallas was formally incorporated as a city on February 2,1856. With construction of railroads, Dallas became a business and trading center and it became an industrial city, attracting workers from Texas, the South and the Midwest. The Praetorian Building of 15 stories, built in 1909, was the first skyscraper west of the Mississippi and it marked the prominence of Dallas as a city

Endangered language
–
An endangered language is a language that is at risk of falling out of use as its speakers die out or shift to speaking another language. Language loss occurs when the language has no native speakers. If eventually no one speaks the language at all, it becomes an extinct language, a dead language may still be observed and studied through recordings or written text, but it is still dead or extinct unless there are fluent speakers. More-commonly spoken languages dominate the less-commonly spoken languages and so the latter eventually disappear, the total number of languages in the world is not known. Estimates vary depending on many factors, the general consensus is that there are between 6000 and 7000 languages currently spoken, and that between 50 and 90% of them will have become extinct by 2100. To recognize an endangered languages, the stages of language extinction follow five steps, the first step is potential endangerment. This is when a language faces endangerment, but there are still a few speakers who are keeping the language current, once a language has reached the endangerment stage, there are only a few speakers left, risking the chances of the language surviving much longer. The third stage of language extinction is seriously endangered, during this stage, a language is unlikely to survive another generation and will soon be extinct. The fourth stage is moribund, followed by the fifth stage extinction, UNESCO operates with four levels of language endangerment beyond safe, based on intergenerational transfer, vulnerable, definitely endangered, severely endangered, and critically endangered. Using an alternative scheme of classification, linguist Michael E, There is a general consensus that the loss of languages harms the cultural diversity of the world. Many projects are under way aimed at preventing or slowing this loss by revitalizing endangered languages and promoting education, across the world, many countries have enacted specific legislation aimed at protecting and stabilizing the language of indigenous speech communities. A few linguists have argued that loss is a natural process that should not be counteracted. The total number of languages in the world is not known. Estimates vary depending on the extent and means of the research undertaken, and the definition of a distinct language, the number of known languages varies over time as some of them become extinct and others are newly discovered. An accurate amount of languages in the world was not yet known until the use of universal, the majority of linguists in the early twentieth century refrained from making estimates. Before then, estimates were frequently the product of guesswork and very low, one of the most active research agencies is SIL International, which maintains a database, Ethnologue, kept up to date by the contributions of linguists globally. Ethnologues 2005 count of languages in its database, excluding duplicates in different countries, was 6,912, of which 32. 8% were in Asia and this contemporary tally must be regarded as a variable number within a range. Areas with a large number of languages that are nearing extinction include, Eastern Siberia, Central Siberia, Northern Australia, Central America

Language death
–
In linguistics, language death occurs when a language loses its last native speaker. Language death may affect any language idiom, including dialects and languages, Language death should not be confused with language attrition, which describes the loss of proficiency in a language at the individual level. Top-to-bottom language death, when language shift begins in an environment such as the government. This is a process of assimilation which may be voluntary or may be forced upon a population and this process is gradual and can occur from either bottom-to-top or top-to-bottom. Languages with a small, geographically isolated population of speakers can also die when their speakers are wiped out by genocide, disease, a language is often declared to be dead even before the last native speaker of the language has died. If there are only a few speakers of a language remaining. A language that has reached such a stage of use is generally considered moribund. Half of the languages of the world are not being taught to new generations of children. This is rarely a sudden event, but a process of each generation learning less and less of the language, until its use is relegated to the domain of traditional use, such as in poetry. One example of this process reaching its conclusion is that of the Dalmatian language, Language death can be fast, when the children are taught to avoid their parents language for reasons such as work opportunities and social status. Many children are rather being taught a lingua franca with English being the most widespread, at other times, minority languages survive much longer, for example when the speakers try to isolate themselves against a majority population. Often, especially historically, governments have tried to promote language death and this process of change has been described by Appel in two categories, though they are not mutually exclusive. Often speakers replace elements of their own language with something from the language they are shifting toward, also, if their heritage language has an element that the new language does not, speakers may drop it. Language revitalization is an attempt to slow or reverse language death, revitalization programs are ongoing in many languages, and have had varying degrees of success. Even in the case of Hebrew, there is a theory that argues that the Hebrew revivalists who wished to speak pure Hebrew failed, the result is a fascinating and multifaceted Israeli language, which is not only multi-layered but also multi-sourced. The revival of a dead language is unlikely without cross-fertilization from the revivalists mother tongue. Other cases of language revitalization which have some degree of success are Irish, Welsh, Hawaiian, Cherokee. There are various ethical, aesthetic and utilitarian benefits of language revival—for example, historical justice, diversity and employability, linguists distinguish between language death and the process where a language becomes a dead language through normal language change, a linguistic phenomenon analogous to pseudoextinction

ZDNet
–
ZDNet is a business technology news website published by CBS Interactive, along with TechRepublic and SmartPlanet. The brand was founded on April 1,1991, as a general interest technology portal from Ziff Davis, ZDNet began as a subscription-based digital service called ZiffNet that offered computing information to users of CompuServe. It featured computer industry forums, events, features and searchable archives, initially, ZiffNet was intended to serve as a common place to find content from all Ziff-Davis print publications. As such, ZiffNet was an expansion on an online service called PCMagNet for readers of PC Magazine. Launched in 1988, PCMagNet in turn was the evolution of Ziff Davis first electronic publishing venture, a bulletin board, on June 20,1995, Ziff-Davis announced the consolidation of its online information services under a single name, ZD Net. The service had grown its membership to 275,000 subscribers across six platforms, CompuServe, Prodigy, AT&T Interchange, a few months prior to the name consolidation, Ziff-Davis expanded onto the World Wide Web under the name ZD Net. Dan Farber, former editor-in-chief of PC Week and MacWeek, was named editor-in-chief of the property, by June, the site was recording web traffic of 2.5 million pageviews per week. The site also expanded overseas, initially to France, Germany, in 1997, the website—now the brands flagship property—underwent another redesign that featured topical channels of content. It also marked the change in name from ZD Net to ZDNet, two months prior, the company launched ZDNet News, or ZDNN, the sites first dedicated section to original reportage. The appointment of digital publishing executive Dan Rosensweig as ZDNets first president capped a year of significant change for the brand, in 1998, ZDNet launched Inter@active Investor, or ZDII, a spin-off website for investors that offered financial news and information on technology companies. On May 11,1998, Ziff-Davis launched ZDTV as the first cable channel and website to offer 24-hour programming about computing. The venture, which was owned by Vulcan Enterprises, was supported with a staff of 170 and incorporated ZDNet content on its website. The channel would later become Tech TV, by the end of 1998, ZDNet was the dominant technology brand online. It led its closest rival, CNET, by a 26 percent margin and was the 13th most popular site on the Web, reaching 8.4 million users, the site would reach an additional 600,000 users within a year. In 1999, Ziff-Davis spun ZDNet off as a company and offered it as a tracking stock, ZDZ, to accompany the parent stock. An initial public offering raised $190 million, but the stock was eliminated in early 2000. The new company soon acquired Updates. com, a software upgrade service and it was incorporated into the sites Help Channel. In 1999, ZDNet also launched Tech Life, a network of six consumer-focused tech sites intended to attract parents, music listeners, gadget enthusiasts, gamers and basic users
