Punk rock
–
Punk rock is a rock music genre that developed in the early to mid-1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as proto-punk music, Punk bands typically produced short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic, many bands self-produce recordings and distribute them through informal channels, the term punk was first used in relation to rock music by some American critics in the early 1970s, to describe garage bands and their devotees. The following year saw punk rock spreading around the world, for the most part, punk took root in local scenes that tended to reject association with the mainstream. An associated punk subculture emerged, expressing youthful rebellion and characterized by distinctive styles of clothing and adornment, by the beginning of the 1980s, faster, more aggressive styles such as hardcore and street punk had become the predominant mode of punk rock. Musicians identifying with or inspired by punk also pursued a range of other variations, giving rise to post-punk. At the end of the 20th century, punk rock had been adopted by the mainstream, as pop punk and punk bands such as Green Day. The first wave of rock was aggressively modern, distancing itself from the bombast. According to Ramones drummer Tommy Ramone, In its initial form, unfortunately, what happens is that people who could not hold a candle to the likes of Hendrix started noodling away. Soon you had endless solos that went nowhere, by 1973, I knew that what was needed was some pure, stripped down, no bullshit rock n roll. In critic Robert Christgaus description, It was also a subculture that rejected the political idealism. Technical accessibility and a DIY spirit are prized in punk rock, in the early days of punk rock, this ethic stood in marked contrast to what those in the scene regarded as the ostentatious musical effects and technological demands of many mainstream rock bands. Musical virtuosity was often looked on with suspicion, according to Holmstrom, punk rock was rock and roll by people who didnt have very many skills as musicians but still felt the need to express themselves through music. In December 1976, the English fanzine Sideburns published an illustration of three chords, captioned This is a chord, this is another, this is a third. The title of a 1980 single by the New York punk band Stimulators, inscribed a catchphrase for punks basic musical approach. The previous year, when the rock revolution began in Great Britain, was to be both a musical and a cultural Year Zero. As a Clash associate describes singer Joe Strummers outlook, Punk rock is meant to be our freedom, were meant to be able to do what we want to do. Scholar Daniel S. Traber argues that attaining authenticity in the identity can be difficult, as the punk scene matured, he observes

Hardcore punk
–
Hardcore punk is a punk rock music genre and subculture that originated in the late 1970s. It is generally faster, harder, and more aggressive than other forms of punk rock, New York punk had a harder-edged sound than its San Francisco counterpart, featuring anti-art expressions of masculine anger, energy and subversive humor. Hardcore punk generally disavows commercialism, the music industry and anything similar to the characteristics of mainstream rock. Hardcore sprouted underground scenes across the United States in the early 1980s, particularly in Washington, New York, New Jersey, and Boston—as well as in Australia, Canada and the United Kingdom. Hardcore has spawned the straight movement and its associated submovements, hardline. Hardcore was heavily involved with the rise of the independent record labels in the 1980s and it has also influenced various music genres that have experienced widespread commercial success, including alternative rock, thrash metal, emo and metalcore. While traditional hardcore has never experienced mainstream success, some of its early pioneers have garnered appreciation over time. In 2011, Rolling Stone writer David Fricke placed Greg Ginn of Black Flag 99th place in his 100 Greatest Guitarists list, although the music genre started in English-speaking western countries, notable hardcore scenes have existed in Italy, Brazil, Japan, Europe and the Middle East. The origin of the hardcore punk is uncertain. The Vancouver-based band D. O. A. may have helped to popularize the term with the title of their 1981 album, Hardcore 81. C. Hardcore historian Steven Blush said that the term hardcore is also a reference to the sense of being fed up with the existing punk, Blush also states that the term refers to an extreme, the absolute most Punk. One definition of the genre is a form of exceptionally harsh punk rock, like the Oi. subgenre of the UK, hardcore punk can be considered an internal music reaction. According to one writer, distressed by the artificiality of much post-punk, lacking the art-school grace of post-punk, hardcore punk favor low key visual aesthetic over extravagance and breaking with original punk rock song patterns. One of the important philosophies in the scene is authenticity. The pejorative term poseur is applied to those who associate with punk and adopt its stylistic attributes but are deemed not to share or understand the underlying values and philosophy. Joe Keithley, the vocalist of D. O. A. said in an interview, in the vein of earlier punk rock, most hardcore punk bands have followed the traditional singer/guitar/bass/drum format. The songwriting has more emphasis on rather than melody. Critic Steven Blush writes The Sex Pistols were still rocknroll. like the craziest version of Chuck Berry, Hardcore was a radical departure from that

Dead Kennedys
–
Dead Kennedys are an American punk rock band that formed in San Francisco, California, in 1978. The band was one of the first American hardcore bands to make a significant impact in the United Kingdom, Dead Kennedys lyrics were usually political in nature, satirizing establishment political figures and authority in general, as well as popular culture and even the punk movement itself. During their initial incarnation between 1978 and 1986, they attracted considerable controversy for their lyrics and artwork. This culminated in an obscenity trial between 1985 and 1986, which resulted in a hung jury, the group released a total of four studio albums and one EP before disbanding in 1986. Following the bands dissolution, Biafra continued to collaborate and record other artists including D. O. A. NoMeansNo and his own bands Lard and the Guantanamo School of Medicine, in 2000, Jello Biafra lost an acrimonious legal case initiated by his former Dead Kennedys band mates over songwriting credits and unpaid royalties. In 2001, the band reformed without Biafra, various singers have since been recruited for vocal duties, the original band lineup consisted of Jello Biafra on vocals, East Bay Ray on guitar, Klaus Flouride on bass, and Ted on drums and percussion. This lineup recorded their first demos, in early to mid July, the band recruited 6025 as a rhythm guitarist. Their first live show was on July 19,1978 at Mabuhay Gardens in San Francisco and they were the opening act on a bill that included DV8 and Negative Trend with The Offs headlining. Dead Kennedys played numerous shows at local venues afterwards, due to the provocative name of the band, they sometimes played under pseudonyms, including The DKs, The Sharks, The Creamsicles and The Pink Twinkies. The bands real name generated controversy,22, the 15th anniversary of John F. Kennedys assassination. Despite mounting protests, the owner of Mabuhay declared, I cant cancel them NOW—theres a contract, not, apparently, the kind of contract some people have in mind. However, despite popular belief, the name was not meant to insult the Kennedy family,6025 left the band in March 1979 under somewhat unclear circumstances, generally considered to be musical differences. In June, the released their first single, California Über Alles, on Biafra and East Bay Rays independent label. The band followed with a poorly attended East Coast tour, being a new and fairly unknown band at the time, in early 1980, they recorded and released the single Holiday in Cambodia. In June, the recorded their debut album, Fresh Fruit for Rotting Vegetables. The album reached number 33 on the UK Albums Chart, on March 25,1980, Dead Kennedys were invited to perform California Über Allesat the Bay Area Music Awards in an effort to give the event some new wave credibility, in the words of the organizers. The day of the performance was spent practicing the song they were asked to play, Weve gotta prove that were adults now

United States
–
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

Italy
–
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world

Nuclear disarmament
–
Nuclear disarmament refers to both the act of reducing or eliminating nuclear weapons and to the end state of a nuclear-weapons-free world, in which nuclear weapons are completely eliminated. There have been many large demonstrations and protests. On June 12,1982, one million people demonstrated in New York Citys Central Park against nuclear weapons and it was the largest anti-nuclear protest and the largest political demonstration in American history. In recent years, some U. S. elder statesmen have also advocated nuclear disarmament, the four have created the Nuclear Security Project to advance this agenda. Organisations such as Global Zero, an international group of 300 world leaders dedicated to achieving nuclear disarmament, have also been established. Proponents of nuclear disarmament say that it would lessen the probability of nuclear war occurring, critics of nuclear disarmament say that it would undermine deterrence. In 1945 in the New Mexico desert, American scientists conducted Trinity, even before the Trinity test, national leaders debated the impact of nuclear weapons on domestic and foreign policy. On August 6,1945, towards the end of World War II, subsequently, the world’s nuclear weapons stockpiles grew. Operation Crossroads was a series of nuclear tests conducted by the United States at Bikini Atoll in the Pacific Ocean in the summer of 1946. Its purpose was to test the effect of weapons on naval ships. Pressure to cancel Operation Crossroads came from scientists and diplomats, manhattan Project scientists argued that further nuclear testing was unnecessary and environmentally dangerous. A Los Alamos study warned the water near a recent surface explosion will be a witchs brew of radioactivity, to prepare the atoll for the nuclear tests, Bikinis native residents were evicted from their homes and resettled on smaller, uninhabited islands where they were unable to sustain themselves. Radioactive fallout from nuclear testing was first drawn to public attention in 1954 when a Hydrogen bomb test in the Pacific contaminated the crew of the Japanese fishing boat Lucky Dragon. One of the fishermen died in Japan seven months later, the incident caused widespread concern around the world and provided a decisive impetus for the emergence of the anti-nuclear weapons movement in many countries. The anti-nuclear weapons movement grew rapidly because for many people the atomic bomb encapsulated the very worst direction in which society was moving, Peace movements emerged in Japan and in 1954 they converged to form a unified Japanese Council Against Atomic and Hydrogen Bombs. Japanese opposition to the Pacific nuclear weapons tests was widespread, CND organised Aldermaston marches into the late 1960s when tens of thousands of people took part in the four-day events. On November 1,1961, at the height of the Cold War and it was the largest national womens peace protest of the 20th century. In 1958, Linus Pauling and his wife presented the United Nations with the petition signed by more than 11,000 scientists calling for an end to nuclear-weapon testing, Pauling started the International League of Humanists in 1974

Imperialism
–
Imperialism is an action that involves a country extending its power by the acquisition of territories. It may also include the exploitation of these territories, an action that is linked to colonialism, colonialism is generally regarded as an expression of imperialism. However, both are examples of imperialism, the word imperialism originated from the Latin word imperium, which means supreme power. It first became common in Great Britain, during the 1870s and was used with a negative connotation, the term was and is mainly applied to Western political and economic dominance, especially in Asia and Africa, in the 19th and 20th centuries. Its precise meaning continues to be debated by scholars, some writers, such as Edward Said, use the term more broadly to describe any system of domination and subordination organised with an imperial center and a periphery. This definition encompasses both nominal empires and neocolonialism, the word empire comes from the Latin word imperium, for which the closest modern English equivalent would perhaps be sovereignty, or simply rule. The greatest distinction of an empire is through the amount of land that a nation has conquered and expanded, Political power grew from conquering land, however cultural and economic aspects flourished through sea and trade routes. A distinction about empires is that although political empires were built mostly by expansion overland, economic, some of the main aspects of trade that went overseas consisted of animals and plant products. European empires in Asia and Africa have come to be seen as the forms of imperialism. European expansion caused the world to be divided by how developed, the two main regions are the core and the periphery. The core consists of areas of income and profit, the periphery is on the opposing side of the spectrum consisting of areas of low income. These critical theories of Geo-politics have led to increased discussion of the meaning and this idea from Lenin stresses how important new political world order has become in our modern era. Geopolitics now focuses on states becoming major players in the market, some states today are viewed as empires due to their political. The term imperialism is often conflated with colonialism, however scholars have argued that each have their own distinct definition. Imperialism and colonialism have been used in order to describe ones superiority, domination, colonialism in modern usage also tends to imply a degree of geographic separation between the colony and the imperial power. Thus it can be said that imperialism includes some form of colonialism, colonialism is seen to be the architect deciding how to start dominating areas and then imperialism can be seen as creating the idea behind conquest cooperating with colonialism. Colonialism is when the imperial nation begins a conquest over an area, colonialisms core meaning is the exploitation of the valuable assets and supplies of the nation that was conquered and the conquering nation then gaining the benefits from the spoils of the war. The meaning of imperialism is to create an empire, by conquering the states lands

Radiation
–
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles, Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules, and break chemical bonds. This is an important distinction due to the difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, gamma rays, X-rays and the higher energy range of ultraviolet light constitute the ionizing part of the electromagnetic spectrum. The lower-energy, longer-wavelength part of the spectrum including visible light, infrared light, microwaves and this type of radiation only damages cells if the intensity is high enough to cause excessive heating. Ultraviolet radiation has some features of both ionizing and non-ionizing radiation and these properties derive from ultraviolets power to alter chemical bonds, even without having quite enough energy to ionize atoms. The word radiation arises from the phenomenon of waves radiating from a source and this aspect leads to a system of measurements and physical units that are applicable to all types of radiation. This law does not apply close to a source of radiation or for focused beams. Radiation with sufficiently high energy can ionize atoms, that is to say it can knock electrons off atoms, ionization occurs when an electron is stripped from an electron shell of the atom, which leaves the atom with a net positive charge. Because living cells and, more importantly, the DNA in those cells can be damaged by this ionization, thus ionizing radiation is somewhat artificially separated from particle radiation and electromagnetic radiation, simply due to its great potential for biological damage. While an individual cell is made of trillions of atoms, only a fraction of those will be ionized at low to moderate radiation powers. If the source of the radiation is a radioactive material or a nuclear process such as fission or fusion. Particle radiation is subatomic particles accelerated to relativistic speeds by nuclear reactions, because of their momenta they are quite capable of knocking out electrons and ionizing materials, but since most have an electrical charge, they dont have the penetrating power of ionizing radiation. The exception is neutron particles, see below, there are several different kinds of these particles, but the majority are alpha particles, beta particles, neutrons, and protons. Roughly speaking, photons and particles with energies above about 10 electron volts are ionizing, particle radiation from radioactive material or cosmic rays almost invariably carries enough energy to be ionizing. The radiation is invisible and not directly detectable by human senses, as a result, in some cases, it may lead to secondary emission of visible light upon its interaction with matter, as in the case of Cherenkov radiation and radio-luminescence. Ionizing radiation has many uses in medicine, research and construction. Ultraviolet, of wavelengths from 10 nm to 125 nm, ionizes air molecules, causing it to be absorbed by air

Pollution
–
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution, Air pollution has always accompanied civilizations. Pollution started from prehistoric times when man created the first fires, metal forging appears to be a key turning point in the creation of significant air pollution levels outside the home. The burning of coal and wood, and the presence of horses in concentrated areas made the cities the cesspools of pollution. The Industrial Revolution brought an infusion of untreated chemicals and wastes into local streams that served as the water supply, king Edward I of England banned the burning of sea-coal by proclamation in London in 1272, after its smoke became a problem. But the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow and it was the industrial revolution that gave birth to environmental pollution as we know it today. London also recorded one of the extreme cases of water quality problems with the Great Stink on the Thames of 1858. Pollution issues escalated as population growth far exceeded view ability of neighborhoods to handle their waste problem, reformers began to demand sewer systems, and clean water. In 1870, the conditions in Berlin were among the worst in Europe. There were no toilets in the streets or squares. Visitors, especially women, often became desperate when nature called, in the public buildings the sanitary facilities were unbelievably primitive. As a metropolis, Berlin did not emerge from a state of barbarism into civilization until after 1870. Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in 1881, as historian Martin Melosi notes, The generation that first saw automobiles replacing the horses saw cars as miracles of cleanliness. By the 1940s, however, automobile-caused smog was an issue in Los Angeles. Other cities followed around the country early in the 20th century. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late 1940s, Air pollution would continue to be a problem in England, especially later during the industrial revolution, and extending into the recent past with the Great Smog of 1952. Awareness of atmospheric pollution spread widely after World War II, with fears triggered by reports of fallout from atomic warfare. Then a non-nuclear event, The Great Smog of 1952 in London and this prompted some of the first major modern environmental legislation, The Clean Air Act of 1956

Japan
–
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon
