Phonograph record
–
The groove usually starts near the periphery and ends near the center of the disc. The phonograph disc record was the medium used for music reproduction until late in the 20th century. It had co-existed with the cylinder from the late 1880s. Records retained the largest market share even when new formats such as compact cassette were mass-marketed, by the late 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the vinyl record left the mainstream in 1991. The phonograph record has made a resurgence in the early 21st century –9.2 million records were sold in the U. S. in 2014. Likewise, in the UK sales have increased five-fold from 2009 to 2014, as of 2017,48 record pressing facilities remain worldwide,18 in the United States and 30 in other countries. The increased popularity of vinyl has led to the investment in new, only two producers of lacquers remains, Apollo Masters in California, USA, and MDC in Japan. Vinyl records may be scratched or warped if stored incorrectly but if they are not exposed to heat or broken. The large cover are valued by collectors and artists for the space given for visual expression, in the 2000s, these tracings were first scanned by audio engineers and digitally converted into audible sound. Phonautograms of singing and speech made by Scott in 1860 were played back as sound for the first time in 2008, along with a tuning fork tone and unintelligible snippets recorded as early as 1857, these are the earliest known recordings of sound. In 1877, Thomas Edison invented the phonograph, unlike the phonautograph, it was capable of both recording and reproducing sound. Despite the similarity of name, there is no evidence that Edisons phonograph was based on Scotts phonautograph. Edison first tried recording sound on a paper tape, with the idea of creating a telephone repeater analogous to the telegraph repeater he had been working on. The tinfoil was wrapped around a metal cylinder and a sound-vibrated stylus indented the tinfoil while the cylinder was rotated. The recording could be played back immediately, Edison also invented variations of the phonograph that used tape and disc formats. A decade later, Edison developed a greatly improved phonograph that used a wax cylinder instead of a foil sheet. This proved to be both a better-sounding and far more useful and durable device, the wax phonograph cylinder created the recorded sound market at the end of the 1880s and dominated it through the early years of the 20th century. Berliners earliest discs, first marketed in 1889, but only in Europe, were 12.5 cm in diameter, both the records and the machine were adequate only for use as a toy or curiosity, due to the limited sound quality

London
–
London /ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south east of the island of Great Britain and it was founded by the Romans, who named it Londinium. Londons ancient core, the City of London, largely retains its 1. 12-square-mile medieval boundaries. London is a global city in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism. It is crowned as the worlds largest financial centre and has the fifth- or sixth-largest metropolitan area GDP in the world, London is a world cultural capital. It is the worlds most-visited city as measured by international arrivals and has the worlds largest city airport system measured by passenger traffic, London is the worlds leading investment destination, hosting more international retailers and ultra high-net-worth individuals than any other city. Londons universities form the largest concentration of education institutes in Europe. In 2012, London became the first city to have hosted the modern Summer Olympic Games three times, London has a diverse range of people and cultures, and more than 300 languages are spoken in the region. Its estimated mid-2015 municipal population was 8,673,713, the largest of any city in the European Union, Londons urban area is the second most populous in the EU, after Paris, with 9,787,426 inhabitants at the 2011 census. The citys metropolitan area is the most populous in the EU with 13,879,757 inhabitants, the city-region therefore has a similar land area and population to that of the New York metropolitan area. London was the worlds most populous city from around 1831 to 1925, Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Pauls Cathedral, Tower Bridge, Trafalgar Square, and The Shard. The London Underground is the oldest underground railway network in the world, the etymology of London is uncertain. It is an ancient name, found in sources from the 2nd century and it is recorded c.121 as Londinium, which points to Romano-British origin, and hand-written Roman tablets recovered in the city originating from AD 65/70-80 include the word Londinio. The earliest attempted explanation, now disregarded, is attributed to Geoffrey of Monmouth in Historia Regum Britanniae and this had it that the name originated from a supposed King Lud, who had allegedly taken over the city and named it Kaerlud. From 1898, it was accepted that the name was of Celtic origin and meant place belonging to a man called *Londinos. The ultimate difficulty lies in reconciling the Latin form Londinium with the modern Welsh Llundain, which should demand a form *lōndinion, from earlier *loundiniom. The possibility cannot be ruled out that the Welsh name was borrowed back in from English at a later date, and thus cannot be used as a basis from which to reconstruct the original name. Until 1889, the name London officially applied only to the City of London, two recent discoveries indicate probable very early settlements near the Thames in the London area

Synth-pop
–
Synth-pop is a subgenre of new wave music that first became prominent in the late 1970s and features the synthesizer as the dominant musical instrument. It was prefigured in the 1960s and early 1970s by the use of synthesizers in progressive rock, electronic, art rock, disco, and particularly the Krautrock of bands like Kraftwerk. It arose as a genre in Japan and the United Kingdom in the post-punk era as part of the new wave movement of the late-1970s to the mid-1980s. In Japan, Yellow Magic Orchestras success opened the way for bands such as P-Model, Plastics. The development of polyphonic synthesizers, the definition of MIDI. This, its adoption by the acts from the New Romantic movement, together with the rise of MTV. Synth-pop is sometimes deployed interchangeably with electropop, but electropop may also denote a variant of synth-pop that places emphasis on a harder. In the late 1980s duos such as Erasure and Pet Shop Boys adopted a style that was successful on the US dance-charts. Some artists and bands were criticised for gender bending, Synth-pop was defined by its primary use of synthesizers, drum machines and sequencers, sometimes using them to replace all other instruments. Borthwick and Moy have described the genre as diverse but, many synth-pop musicians had limited musical skills, relying on the technology to produce or reproduce the music. The result was often minimalist, with grooves that were woven together from simple repeated riffs often with no harmonic progression to speak of. Early synth-pop has been described as eerie, sterile, and vaguely menacing, using droning electronics with little change in inflection, common lyrical themes of synth-pop songs were isolation, urban anomie, and feelings of being emotionally cold and hollow. Synthesizers were increasingly used to imitate the conventional and clichéd sound of orchestras, thin, treble-dominant, synthesized melodies and simple drum programmes gave way to thick, and compressed production, and a more conventional drum sound. Lyrics were generally optimistic, dealing with more traditional subject matter for pop music such as romance, escapism. According to music writer Simon Reynolds, the hallmark of 1980s synth-pop was its emotional, at times operatic singers such as Marc Almond, Alison Moyet and Annie Lennox. Because synthesizers removed the need for groups of musicians, these singers were often part of a duo where their partner played all the instrumentation. Later synth-pop saw a shift to a style influenced by other genres. Electronic musical synthesizers that could be used practically in a recording studio became available in the mid-1960s, the portable Minimoog, which allowed much easier use, particularly in live performance was widely adopted by progressive rock musicians such as Richard Wright of Pink Floyd and Rick Wakeman of Yes

New wave music
–
New wave is a genre of rock music popular from the late 1970s to the mid-1980s with ties to 1970s punk rock. New wave moved away from smooth blues and rock and roll sounds to create pop music that incorporated electronic and experimental music, mod, initially new wave was similar to punk rock, before becoming a distinct genre. It subsequently engendered subgenres and fusions, including synth-pop, college rock, common characteristics of new wave music include the use of synthesizers and electronic productions, the importance of styling and the arts, as well as diversity. In the mid-1980s, differences between new wave and other genres began to blur. New wave has enjoyed resurgences since the 1990s, after a rising nostalgia for several new wave-influenced artists, subsequently, the genre influenced other genres. During the 2000s, a number of acts explored new wave and post-punk influences, such as the Strokes, Interpol, Franz Ferdinand and these acts were sometimes labeled new wave of new wave. The catch-all nature of new music has been a source of much confusion. The 1985 discography Whos New Wave in Music listed artists in over 130 separate categories, the New Rolling Stone Encyclopedia of Rock calls the term virtually meaningless, while AllMusic mentions stylistic diversity. New wave first emerged as a genre in the early 1970s, used by critics including Nick Kent and Dave Marsh to classify such New York-based groups as the Velvet Underground. It gained currency beginning in 1976 when it appeared in UK punk fanzines such as Sniffin Glue and newsagent music weeklies such as Melody Maker and New Musical Express. In November 1976 Caroline Coon used Malcolm McLarens term new wave to designate music by bands not exactly punk, the term was also used in that sense by music journalist Charles Shaar Murray in his comments about the Boomtown Rats. For a period of time in 1976 and 1977, the new wave. By the end of 1977, new wave had replaced punk as the definition for new music in the UK. As radio consultants in the United States had advised their clients that punk rock was a fad, like the filmmakers of the French new wave movement, its new artists were anti-corporate and experimental. At first, most U. S. writers exclusively used the new wave for British punk acts. Music historian Vernon Joynson claimed that new wave emerged in the UK in late 1976, in the U. S. the first new wavers were the not-so-punk acts associated with the New York club CBGB. CBGB owner Hilly Kristal, referring to the first show of the band Television at his club in March 1974, said, furthermore, many artists who would have originally been classified as punk were also termed new wave. A1977 Phonogram Records compilation album of the same name features US artists including the Dead Boys, Ramones, Talking Heads, New wave is much more closely tied to punk and came and went more quickly in the United Kingdom than in the United States

Factory Records
–
Like the label 4AD Records, Factory Records used a creative team which gave the label and the artists recording for it a particular sound and image. The label employed a unique cataloguing system that gave a not just to its musical releases. At that time there was a label in Manchester called Rabid Records, run by Tosh Ryan. It had several successful acts, including Slaughter & The Dogs, John Cooper Clarke, after his seminal TV series So It Goes, Tony Wilson was interested in the way Rabid Records ran, and was convinced that the real money and power were in album sales. With a lot of discussion, Tony Wilson, Rob Gretton and Alan Erasmus set up Factory Records, the Factory name was first used for a club in May of that year, which featured local bands including The Durutti Column, Cabaret Voltaire from Sheffield, and Joy Division. Peter Saville designed advertising for the club, and in September Factory released an EP of music by acts who had played at the club called A Factory Sample, in 1978, Wilson compered the new wave afternoon at Deeply Vale Festival. The Factory label set up an office in Erasmus home on the first floor of 86 Palatine Road, singles followed by A Certain Ratio and Orchestral Manoeuvres in the Dark. The first Factory LP, Joy Divisions Unknown Pleasures, was released in June, in January 1980, The Return of the Durutti Column was released, the first in a long series of releases by guitarist Vini Reilly. In May, Joy Division singer Ian Curtis committed suicide shortly before a tour of the USA. The following month saw Joy Divisions single Love Will Tear Us Apart reach the UK top twenty, in late 1980, the remaining members of Joy Division decided to continue as New Order. Hannett left the label, as he had wanted to open a studio instead. Saville also quit as a due to problems with payments. Wilson, Erasmus and Gretton formed Factory Communications Ltd, the Haçienda opened in May 1982. Adjusting bar prices failed to help matters as by the crowds were increasingly preferring ecstasy to alcohol. Therefore the Haçienda ended up costing tens of thousands of pounds every month, in 1983 New Orders Blue Monday became an international chart hit. Saville noted that nobody at Factory expected Blue Monday to be a successful record at all. 1985 saw the first release by Happy Mondays, New Order and Happy Mondays became the most successful bands on the label, bankrolling a host of other projects. Factory, and the Haçienda, became a hub of the emerging techno and acid house genres

YouTube
–
YouTube is an American video-sharing website headquartered in San Bruno, California. The service was created by three former PayPal employees—Chad Hurley, Steve Chen, and Jawed Karim—in February 2005, Google bought the site in November 2006 for US$1.65 billion, YouTube now operates as one of Googles subsidiaries. Unregistered users can watch videos on the site, while registered users are permitted to upload an unlimited number of videos. Videos deemed potentially offensive are available only to registered users affirming themselves to be at least 18 years old, YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, Hurley had studied design at Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign. Karim could not easily find video clips of either event online, Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not. YouTube began as a venture capital-funded technology startup, primarily from an $11.5 million investment by Sequoia Capital between November 2005 and April 2006, YouTubes early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California. The domain name www. youtube. com was activated on February 14,2005, the first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo. The video was uploaded on April 23,2005, and can still be viewed on the site, YouTube offered the public a beta test of the site in May 2005. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005. Following a $3.5 million investment from Sequoia Capital in November, the site grew rapidly, and in July 2006 the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day. The site has 800 million unique users a month and it is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. The choice of the name www. youtube. com led to problems for a similarly named website, the sites owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube has since changed the name of its website to www. utubeonline. com, in October 2006, Google Inc. announced that it had acquired YouTube for $1.65 billion in Google stock, and the deal was finalized on November 13,2006. In March 2010, YouTube began free streaming of certain content, according to YouTube, this was the first worldwide free online broadcast of a major sporting event. On March 31,2010, the YouTube website launched a new design, with the aim of simplifying the interface, Google product manager Shiva Rajaraman commented, We really felt like we needed to step back and remove the clutter. In May 2010, YouTube videos were watched more than two times per day. This increased to three billion in May 2011, and four billion in January 2012, in February 2017, one billion hours of YouTube was watched every day

Rock music
–
It has its roots in 1940s and 1950s rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of genres such as electric blues and folk. Musically, rock has centered on the guitar, usually as part of a rock group with electric bass guitar. Typically, rock is song-based music usually with a 4/4 time signature using a verse-chorus form, like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political in emphasis. Punk was an influence into the 1980s on the subsequent development of subgenres, including new wave, post-punk. From the 1990s alternative rock began to rock music and break through into the mainstream in the form of grunge, Britpop. Similarly, 1970s punk culture spawned the visually distinctive goth and emo subcultures and this trio of instruments has often been complemented by the inclusion of other instruments, particularly keyboards such as the piano, Hammond organ and synthesizers. The basic rock instrumentation was adapted from the blues band instrumentation. A group of musicians performing rock music is termed a rock band or rock group, Rock music is traditionally built on a foundation of simple unsyncopated rhythms in a 4/4 meter, with a repetitive snare drum back beat on beats two and four. Melodies are often derived from older musical modes, including the Dorian and Mixolydian, harmonies range from the common triad to parallel fourths and fifths and dissonant harmonic progressions. Critics have stressed the eclecticism and stylistic diversity of rock, because of its complex history and tendency to borrow from other musical and cultural forms, it has been argued that it is impossible to bind rock music to a rigidly delineated musical definition. These themes were inherited from a variety of sources, including the Tin Pan Alley pop tradition, folk music and rhythm, as a result, it has been seen as articulating the concerns of this group in both style and lyrics. Christgau, writing in 1972, said in spite of some exceptions, rock and roll usually implies an identification of male sexuality, according to Simon Frith rock was something more than pop, something more than rock and roll. Rock musicians combined an emphasis on skill and technique with the concept of art as artistic expression, original. The foundations of music are in rock and roll, which originated in the United States during the late 1940s and early 1950s. Its immediate origins lay in a melding of various musical genres of the time, including rhythm and blues and gospel music, with country. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, debate surrounds which record should be considered the first rock and roll record. Other artists with rock and roll hits included Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis

Victoria (Australia)
–
Victoria is a state in southeast Australia. Victoria is Australias most densely populated state and its second-most populous state overall, most of its population is concentrated in the area surrounding Port Phillip Bay, which includes the metropolitan area of its state capital and largest city, Melbourne, Australias second-largest city. Prior to British European settlement, the area now constituting Victoria was inhabited by a number of Aboriginal peoples. With Great Britain having claimed the entire Australian continent east of the 135th meridian east in 1788, Victoria was included in the wider colony of New South Wales. The first settlement in the area occurred in 1803 at Sullivan Bay, and much of what is now Victoria was included in the Port Phillip District in 1836, Victoria was officially created as a separate colony in 1851, and achieved self-government in 1855. Politically, Victoria has 37 seats in the Australian House of Representatives and 12 seats in the Australian Senate, at state level, the Parliament of Victoria consists of the Legislative Assembly and the Legislative Council. Victoria is currently governed by the Labor Party, with Daniel Andrews the current Premier, the personal representative of the Queen of Australia in the state is the Governor of Victoria, currently Linda Dessau. Local government is concentrated in 79 municipal districts, including 33 cities, although a number of unincorporated areas still exist, Victorias total gross state product is ranked second in Australia, although Victoria is ranked fourth in terms of GSP per capita because of its limited mining activity. Culturally, Melbourne is home to a number of museums, art galleries and theatres and is described as the sporting capital of Australia. The Melbourne Cricket Ground is the largest stadium in Australia, and the host of the 1956 Summer Olympics, Victoria has eight public universities, with the oldest, the University of Melbourne, having been founded in 1853. Victoria, like Queensland, was named after Queen Victoria, who had been on the British throne for 14 years when the colony was established in 1851. The first British settlement in the later known as Victoria was established in October 1803 under Lieutenant-Governor David Collins at Sullivan Bay on Port Phillip. In the year 1826 Colonel Stewart, Captain S. Wright, fly and the brigs Dragon and Amity, took a number of convicts and a small force composed of detachments of the 3rd and 93rd regiments. Victorias next settlement was at Portland, on the south west coast of what is now Victoria, edward Henty settled Portland Bay in 1834. Melbourne was founded in 1835 by John Batman, who set up a base in Indented Head, from settlement the region around Melbourne was known as the Port Phillip District, a separately administered part of New South Wales. Shortly after the now known as Geelong was surveyed by Assistant Surveyor W. H. Smythe. And in 1838 Geelong was officially declared a town, despite earlier white settlements dating back to 1826, days later, still in 1851 gold was discovered near Ballarat, and subsequently at Bendigo. Later discoveries occurred at sites across Victoria

Fairlight CMI
–
It was one of the earliest music workstations with an embedded digital sampling synthesizer. It rose to prominence in the early 1980s and competed in the market with the Synclavier from New England Digital, after his classmate, Peter Vogel, graduated from high school in 1975, Ryrie showed him Wendy Carlos album Switched-on Bach, which was produced with a Moog synthesizer. Ryrie had always wanted to make a better than the Moog. In December of that year, he and Vogel formed a company intended to manufacture digital synthesizers. It was called Fairlight, which the name came from the hydrofoil ferry passing before Ryries grandmothers home in Sydney harbour and they had initially thought of making an analogue synth that was digitally controlled, given that the Moog was much more difficult to control. After the six months that followed involving the two in the companys basement failing to come up with ideas, they met Motorola consultant Tony Furse, despite this, the machine was unable to create harmonic partials, therefore the sounds that came from the synth were sterile and unimaginative. As a last-minute attempt of producing a digital synthesizer that could make complex patches, Vogel recalled in a 2005 interview about how he came up with this concept, I had this random idea late one night, probably in 1978. I thought that if we took a sample of an instrument and had a look at the harmonics we could get an idea of how to synthesise it. We were already making interesting sounds but we were still a way from getting it to sound like a real instrument. So I hooked an analogue-to-digital converter up to the radio and sampled maybe a second of some piano piece, then I wondered how it would sound if I played it back without doing anything. So I played it back at different pitches and it sounded remarkably like a piano and this had never been done before. By todays standards it was a pretty awful piano sound, so I rapidly realised that we didnt have to bother with all the synthesis stuff. Just take the sounds, whack them in the memory and away you go, however, Vogel has said that the low quality of the sounds was what gave them their own character. Its Music Composition Language feature was frequently criticized, with reviewers calling it too difficult for empirical users. Other primitive aspects included its limited amount of RAM and its green, still, Vogel was unsure if there would be enough interest in the product. In the summer of 1979, Peter Vogel went to the home of English singer-songwriter Peter Gabriel, until that time everything that captured sound had been tape-based. The Fairlight CMI was like a more reliable and versatile digital Mellotron. Peter was completely thrilled, and instantly put the machine to use during the week that Peter Vogel stayed at his house

Music video
–
A music video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to more than just a song. Tie ins and merchandising could be used in toys or marketing campaigns for food, although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by terms including illustrated song, filmed insert, promotional film, promotional clip, promotional video, song video. Music videos use a range of styles of contemporary videomaking techniques, including animation, live action filming, documentaries. Some music videos blend different styles, such as animation, music, combining these styles and techniques has become more popular because of the variation it presents to the audience. Many music videos interpret images and scenes from the songs lyrics, other music videos may be without a set concept, being merely a filmed version of the songs live performance. Product placement is a technique in music videos, exemplified by the appearance of the Beats Pill in numerous hip hop videos. In 1894, sheet music publishers Edward B, marks and Joe Stern hired electrician George Thomas and various performers to promote sales of their song The Little Lost Child. Using a magic lantern, Thomas projected a series of images on a screen simultaneous to live performances. This would become a form of entertainment known as the illustrated song. In 1926, with the arrival of many musical short films were produced. Vitaphone shorts featured many bands, vocalists and dancers, early 1930s cartoons featured popular musicians performing their hit songs on-camera in live-action segments during the cartoons. The early animated films by Walt Disney, such as the Silly Symphonies shorts and especially Fantasia, the Warner Brothers cartoons, even today billed as Looney Tunes and Merrie Melodies, were initially fashioned around specific songs from upcoming Warner Brothers musical films. Live action musical shorts, featuring such performers as Cab Calloway, were also distributed to theaters. Blues singer Bessie Smith appeared in a short film called St. Louis Blues featuring a dramatized performance of the hit song. Numerous other musicians appeared in short musical subjects during this period, soundies, produced and released from 1940 to 1947, were musical films that often included short dance sequences, similar to later music videos

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Lithography
–
Lithography is a method of printing originally based on the immiscibility of oil and water. The printing is from a stone or a plate with a smooth surface. It was invented in 1796 by German author and actor Alois Senefelder as a method of publishing theatrical works. Lithography can be used to print text or artwork onto paper or other suitable material, Lithography originally used an image drawn with oil, fat, or wax onto the surface of a smooth, level lithographic limestone plate. The stone was treated with a mixture of acid and gum arabic, when the stone was subsequently moistened, these etched areas retained water, an oil-based ink could then be applied and would be repelled by the water, sticking only to the original drawing. The ink would finally be transferred to a paper sheet. This traditional technique is used in some fine art printmaking applications. In modern lithography, the image is made of a coating applied to a flexible aluminum plate. The image can be printed directly from the plate, or it can be offset, by transferring the image onto a sheet for printing. In fact, photolithography is used synonymously with offset printing, the technique as well as the term were introduced in Europe in the 1850s. Beginning in the 1960s, photolithography has played an important role in the fabrication, Lithography uses simple chemical processes to create an image. For instance, the part of an image is a water-repelling substance. Thus, when the plate is introduced to a printing ink and water mixture, the ink will adhere to the positive image. This allows a flat print plate to be used, enabling much longer, Lithography was invented by Alois Senefelder in the Kingdom of Bavaria in 1796. In the early days of lithography, a piece of limestone was used. After the oil-based image was put on the surface, a solution of gum arabic in water was applied, during printing, water adhered to the gum arabic surfaces and was repelled by the oily parts, while the oily ink used for printing did the opposite. Lithography works because of the repulsion of oil and water. The image is drawn on the surface of the print plate with a fat or oil-based medium such as a wax crayon, which may be pigmented to make the drawing visible
