CASE 466 - The history of The Czech republic



Despite its landlocked location, there were brief periods in the Middle Ages during which Bohemia had access to the Baltic and Adriatic seacoasts. A region of rolling hills and mountains, Bohemia is dominated by the national capital, Prague. Set on the Vltava River, this picturesque city of bridges and spires is the unique work of generations of artists brought in by the rulers of Bohemia. Perhaps only the French are as focused on their capital, Paris, as the Czechs are on theirs; of the two, Prague has a more magical quality for many. Called “the handsomest city of Europe” since the 18th century, it has intoxicated writers, poets, and musicians alike. While Prague was the birthplace of the writer Franz Kafka and the poet Rainer Maria Rilke, Brno, Moravia’s largest city, was the site of Gregor Mendel’s groundbreaking genetic experiments in the 19th century and the birthplace of contemporary novelist Milan Kundera. Moravians are as proud of their vineyards and wine as Bohemians are of their breweries and the Pilsner beer that originated in the town of Plzeň (Pilsen), which is also noted as the site of the Škoda Works—a heavy industrial complex that originated with the Habsburg monarchy. Moravia was equally endowed with skilled labour, which helped make Brno into one of the leading industrial towns in textiles and engineering during the 19th century and Ostrava, in the north, into a major coal-mining region, thanks to the vast fossil fuel deposits stretching over from Silesia.



During its 1,000-year history, The czech republic, formally Czechoslovakia has changed shape and reshuffled its population a few times. As the kingdom of Bohemia, it reached its zenith of wealth and power during the 13th and 14th centuries. Through a multitude of cultural, economic, ecclesiastical, and dynastic links, Bohemian kings became directly involved in the affairs of the German rulers of the Holy Roman Empire and opened the country to German colonization, which brought prosperity through silver mining and rapid urbanization. Prague, with the oldest university north of the Alps (Charles University, 1348), functioned as a royal and imperial capital. However, German colonization, which soon accounted for one-third of the total population and disadvantaged the majority Czechs, brought the seeds of discontent, resulting in an ugly, insolvable conflict in the 20th century. In the early 15th century Bohemia witnessed the Hussite revolution, a pre-Reformation movement named for Jan Hus, a follower of the English theologian and reformer John Wycliffe. Religious antagonism prevailed over ethnic tensions when Czechs and Germans jointly led the Protestant uprising that started the Thirty Years’ War (1618–48) against the Catholic Habsburgs, the Austro-German dynasty that ruled Bohemia from 1526 to 1918. After the Habsburg victory, the German language replaced Czech for almost two centuries—until the Czechs experienced an extraordinary linguistic and cultural revival that coincided with the revolutions of 1848 and the spread of industrialization.



The collapse of the Austro-Hungarian Empire at the end of World War I brought the Czechs and Slovaks together for the first time as “Czechoslovaks.” The Czechs became the ruling ethnic group in Czechoslovakia, a new state in which Germans and Hungarians lived as unwilling citizens, bound to become disloyal minorities bent on undermining the democratic constitution engendered by the country’s founders, Tomáš G. Masaryk and Edvard Beneš. Many among this German population turned into Nazi sympathizers with the ascent to power of Adolf Hitler in Germany, whose design on the German-speaking border region of Czechoslovakia was appeased by England and France in the Munich Agreement of September 1938. Emasculated, Czechoslovakia succumbed to direct German invasion six months later. Bohemia and Moravia became a protectorate of the “Greater German Empire,” while Slovakia—whose Hungarian districts were ceded to Hungary—was induced by Hitler to proclaim its independence. After six years of brutal Nazi occupation, Czechoslovakia was reconstituted, this time without Ruthenia (Transcarpathian Ukraine), which was annexed by the Soviet Union. A communist coup in February 1948 sealed Czechoslovakia’s fate as a member of the Soviet bloc for the entire Cold War—though briefly, in the Prague Spring of 1968, a reform movement took over, only to be crushed by Soviet military invasion in August of that year. Still, that experience of freedom produced an underground dissident movement, later called Charter 77, whose leader, playwright Václav Havel, was propelled from prison to the royal castle, becoming the first president of postcommunist Czechoslovakia with the fall of the Berlin Wall in 1989.

CASE 465 - Bitcoin and the future of currency



Bitcoin is a cryptocurrency and a payment system invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto. Bitcoin was introduced on 31 October 2008 to a cryptography mailing list, and released as open-source software in 2009. There have been various claims and speculation concerning the identity of Nakamoto, none of which are confirmed. The system is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain, which uses bitcoin as its unit of account. Since the system works without a central repository or single administrator, the U.S. Treasury categorizes bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed and it is more correctly described as the first decentralized digital currency. Bitcoin is the largest of its kind in terms of total market value and is a cross between a stock and a form of payment. It’s a form of payment because you can use Bitcoins to pay for things. You can buy computers on Tigerdirect.com, you can buy pretty much get anything on Overstock.com OSTK -1.97%, and apparently, some enterprising young California girls are letting you buy cookies with them. You can also send small amounts of currency to people in other countries, without worrying about exchange rates or currency conversion fees. And this last is pretty important. No currency conversion or exchange rates.

It’s a stock because there’s a fixed number of “Bitcoins” in the universe. The value of each Bitcoin fluctuates based on the law of supply and demand. The more people that want to use them, the higher their value. One friend anecdotally reported Bitcoins bought in 2009-2010 for $1 (USD) each were recently sold for $1,200. That’s a lot of appreciation. But it’s not what Bitcoin’s people focus on.



Fiat currency ($£) is created through bank loans and mortgages (debts), out of thin air without having to have physical cash or it be backed by anything. This allows central banks to expand and influence money in circulation without regulation. As long the debter pays off the inflation and minimum requirement payment. There will never be enough money in society to ever pay all the debts off so a disequilibrium occurs where people become detached from their original debt and society constantly has to compete for labor in order to pool enough money out of the continual growth economy money supply and it's not backed or pegged by anything other peoples faith and trust and our national insurance, also u can get mugged in the street with cash or through your bank account or stick it in the Cayman Islands to avoid paying tax. Where as bitcoin it's not impossible but you would need a quantum computer to hack the encryption that it uses, which is also regulated and taxed in units of transactions and it essentially does away with the central bank model and tax evaders, I can buy something off a person on the other side of the world without having to go through say PayPal and then my bank



Blockchain

Number of unspent transaction outputs

The blockchain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority: maintenance of the blockchain is performed by a network of communicating nodes running bitcoin software. Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. The blockchain is a distributed database – to achieve independent verification of the chain of ownership of any and every bitcoin (amount), each network node stores its own copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes. This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight. Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.

Units

The unit of account of the bitcoin system is bitcoin. As of 2014, symbols used to represent bitcoin are BTC, XBT and BitcoinSign.svg. Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), microbitcoin (µBTC, sometimes referred to as a bit), and satoshi. Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoin, one hundred millionth of a bitcoin. A millibitcoin equals to 0.001 bitcoin, one thousandth of bitcoin. One microbitcoin equals to 0.000001 bitcoin, one millionth of a bitcoin.

A proposal was submitted to the Unicode Consortium in October 2015 to add a codepoint for the symbol. As of November 2016, it is in the pipeline for position 20BF in the Currency Symbols block.

Ownership

Simplified chain of ownership. In reality, a transaction can have more than one input and more than one output.

Ownership of bitcoins implies that a user can spend bitcoins associated with a specific address. To do so, a payer must digitally sign the transaction using the corresponding private key. Without knowledge of the private key, the transaction cannot be signed and bitcoins cannot be spent. The network verifies the signature using the public key. If the private key is lost, the bitcoin network will not recognize any other evidence of ownership; the coins are then unusable, and thus effectively lost. For example, in 2013 one user claimed to have lost 7,500 bitcoins, worth $7.5 million at the time, when he accidentally discarded a hard drive containing his private key.

Transactions

A transaction must have one or more inputs. For the transaction to be valid, every input must be an unspent output of a previous transaction. Every input must be digitally signed. The use of multiple inputs corresponds to the use of multiple coins in a cash transaction. A transaction can also have multiple outputs, allowing one to make multiple payments in one go. A transaction output can be specified as an arbitrary multiple of satoshi. As in a cash transaction, the sum of inputs (coins used to pay) can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer. Any input satoshis not accounted for in the transaction outputs become the transaction fee.

Mining

Mining is a record-keeping service. Miners keep the blockchain consistent, complete, and unalterable by repeatedly verifying and collecting newly broadcast transactions into a new group of transactions called a block. Each block contains a cryptographic hash of the previous block, using the SHA-256 hashing algorithm, 7 which links it to the previous block, thus giving the blockchain its name. In order to be accepted by the rest of the network, a new block must contain a so-called proof-of-work. The proof-of-work requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is 0, 1, 2, 3, ... 8) before meeting the difficulty target.

Every 2016 blocks (approximately 14 days), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.

Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.

The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted. As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks (also called confirmations of the given block) increases



We need to maintain and improve upon our already-powerful open-source, cryptographic algorithms and enhance the programs , start ups and ideas being brought forward by young people. We need to fight to encode privacy and our human rights into the very fabric of the world. Edward Snowden said so himself. It is actually part of what spurred him on in divulging the crimes of the NSA and other government agencies

Snowden’s goal for us is to create a more free and equal internet. In an earlier interview with Laura Pointras, Snowden explained:

“The shock of this initial period [after the first revelations] will provide the support needed to build a more equal internet, but this will not work to the advantage of the average person unless science outpaces law. By understanding the mechanisms through which our privacy is violated, we can win here. We can guarantee for all people equal protection against unreasonable search through universal laws, but only if the technical community is willing to face the threat and commit to implementing over-engineered solutions. In the end, we must enforce a principle whereby the only way the powerful may enjoy privacy is when it is the same kind shared by the ordinary: one enforced by the laws of nature, rather than the policies of man.”

By implementing these new cryptographic systems, we may move one step further towards what Snowden envisioned: distributed and secure math-based ecosystems that enhance our privacy and allow us to innovate further in all areas — in government, in finance, in communications, agriculture, building and journalism, etc. Even if you inherently trust our government — I would argue that the price of non-action here is great: Dictators around the world, future corrupt leaders of America, they all stand to benefit if citizens are denied these tools. The old democratic 2 or 3 party highest voted party wins system or constant growth fractional reserve centralized banking systems has and never will work or be fair for everyone and its so expensive, wasteful, uneconomic, creates a higher rich/poor gap and political actions always take years to implement, but an open source cryptographic governence/financial world were absolutely everyone has a say and input, everything is transparent and there to be Search Results analyzed by anyone if they want to could.

CASE 464 - Al Qaeda / ISIS - Terrorism by proxy



As this latest Western manufactured ‘terror nightmare’ continues to unfold in Iraq and Syria, we’ve learned that US President Barack Obama has now asked Congress to authorize direct military aid and equipment to be sent to ‘the rebels’ in Syria. This latest stage of Washington’s project in Syria is said to total $500 million, expanding the covert CIA/FSA training facilities that have ties to ISIS in both Jordan and Turkey… The mainstream media has been spinning overtime with ISIS, touting many dramatic pictures of mass-executions as ‘evidence’ of their takeover of Iraq, and using this crisis yet another pretext to ramp-up military budgets and security threats at home. Most of the ‘mass execution’ images put forward in media have since been exposed as pure fakery, although this hasn’t deterred US and European media ‘experts’ or US State Department, UK Foreign Office officials, tabloid newspapers and news channels. As the ‘ISIS Crisis’ appears to spiral out of control, it exposes the Western government-transnational corporate agenda, that seeks to expand the current proxy war in Iraq, as well as to neighboring nations by directly financing terror rebels – this time with Congressional approval. While many think-tanks and media rooms proclaim to be very much against the terror-grip of Al-Qaeda’s offshoot ISIS by publicly denounce their actions, the $500 million dollar appropriation appears to be a cash injection into the radical destruction of both Iraq and Syria. The current destabilization campaign in Iraq will have a number of unforeseen outcomes, including the fracturing of Syria and Iraq, and the predictable calls from Erbil for a newly formed ‘Kurdish State’ in Northern Iraq.



Islamic State and by its Arabic language acronym Daesh داعش‎‎ is a Salafi jihadist unrecognised state and militant group that follows a fundamentalist, Wahhabi doctrine of Sunni Islam. ISIL gained global notoriety in early 2014 when it drove Iraqi government forces out of key cities in its Western Iraq offensive,[49] followed by its capture of Mosul and the Sinjar massacre. Its adoption of the name Islamic State and its idea of a caliphate have been widely criticised, with the United Nations, various governments, and mainstream Muslim groups rejecting its statehood. This group has been designated a terrorist organisation by the United Nations and many individual countries. ISIL is widely known for its videos of beheadings of both soldiers and civilians, including journalists and aid workers, and its destruction of cultural heritage sites. The United Nations holds ISIL responsible for human rights abuses and war crimes, and Amnesty International has charged the group with ethnic cleansing on a "historic scale" in northern Iraq. In Syria, the group has conducted ground attacks on both government forces and opposition factions. By December 2015, the Islamic State covered a vast landlocked territory in western Iraq and eastern Syria, with a population estimate of 2.8–8 million people, where it enforces its interpretation of sharia law. ISIL is now believed to be operational in 18 countries across the world, including Afghanistan and Pakistan, with "aspiring branches" in Mali, Egypt, Somalia, Bangladesh, Indonesia and the Philippines.



US, Turkey, Israel and Saudi-backed Terrorist Groups Coming Out of Syria

Known terrorist groups have been operating in Syria for over three years now – mostly with the tacit approval of war planners in Washington, London and Paris. Folded into the ‘Syrian Rebel’ confab, these terrorist fighting groups have all but received the full backing of NATO Allies (arms) and Gulf states Qatar and Saudi Arabia (money). They include, but are not limited to, Saudi Intelligence-backed Jabhat al-Nusra or ‘al Nursa Front’, the Libyan Islamic Fighting Group, Abdullah Azzam Brigades and Al Baraa ibn Malik Martyrdom Brigade, the jihadist group Ahrar al-Sham, the PKK (in northeast Syria), and Kata’ib Mohadzherin from the Russian Caucus region – to name only a few.



SIS, ISIL, IS or Daesh – the group has been deliberately engineered by the US, Turkey, Saudi Arabia and Israel to achieve certain geopolitical goals. They are a religious, fundamentalist, Sunni terrorist organization created to terrorize and overthrow certain secular or Shiite Arab nations such as Syria and Iraq, but they are not just “Islamic” and it always always seems to be in favor of the Israeli state. It has systemically tried to divide and conquer its Arab neighbors. It continually complains of Islamic terrorism. Yet, when ISIS comes on the scene as the bloody and barbaric king of Islamic terrorism, it finds no fault with Israel and sees no reason to target a regime which has perpetrated massive injustice against Muslims? This stretches credibility to a snapping point. ISIS and Israel don’t attack each other – they help each other. Israel was treating ISIS soldiers and other anti-Assad rebels in its hospitals! Mortal enemies or best of friends?

CASE 463 - The space race

CASE 463 - Space race



The original Space Race was a 20th-century competition between two Cold War rivals, the Soviet Union (USSR) and the United States (US), for supremacy in spaceflight capability. In 1955, with both the United States and the Soviet Union building ballistic missiles that could be utilized to launch objects into space, the "starting line" was drawn for the Space Race. In separate announcements four days apart, both nations publicly announced that they would launch artificial Earth satellites by 1957 or 1958. On July 29, 1955, James C. Hagerty, president Dwight D. Eisenhower's press secretary, announced that the United States intended to launch "small Earth circling satellites" between July 1, 1957, and December 31, 1958, as part of their contribution to the International Geophysical Year (IGY). Four days later, at the Sixth Congress of International Astronautical Federation in Copenhagen, scientist Leonid I. Sedov spoke to international reporters at the Soviet embassy, and announced his country's intention to launch a satellite as well, in the "near future". On August 30, 1955, Korolev managed to get the Soviet Academy of Sciences to create a commission whose purpose was to beat the Americans into Earth orbit: this was the de facto start date for the Space Race. The Council of Ministers of the Soviet Union began a policy of treating development of its space program as a classified state secret.



Gagarin became a national hero of the Soviet Union and the Eastern Bloc, and a worldwide celebrity. Moscow and other cities in the USSR held mass demonstrations, the scale of which was second only to the World War II Victory Parade of 1945. April 12 was declared Cosmonautics Day in the USSR, and is celebrated today in Russia as one of the official "Commemorative Dates of Russia." In 2011, it was declared the International Day of Human Space Flight by the United Nations.



Human spaceflight after Apollo

In the 1970s, the United States began developing a new generation of reusable orbital spacecraft known as the Space Shuttle, and launched a range of unmanned probes. The USSR continued to develop space station technology with the Salyut program and Mir ('Peace' or 'World', depending on the context) space station, supported by Soyuz spacecraft. They developed their own large space shuttle under the Buran program. The USSR dissolved in 1991 and the remains of its space program mainly passed to Russia. The United States and Russia worked together in space with the Shuttle–Mir Program, and again with the International Space Station.

The Russian R-7 rocket family, which launched the first Sputnik at the beginning of the space race, is still in use today. It services the International Space Station (ISS) as the launcher for both the Soyuz and Progress spacecraft. It also ferries both Russian and American crews to and from the station.

CASE 462 - The different ages of human civilization



Africa provides a comprehensive and contigious time line of human development going back at least 7 million years. Africa, which developed the world's oldest human civilization, gave humanity the use of fire a million and half to two million years ago. It is the home of the first tools, astronomy, jewelry, fishing, mathematics, crops, art, use of pigments, cutting and other pointed instruments and animal domestication. In short Africa gave the world human civilization. Millions of years ago human life started in Africa, Australopithecus aphaeresis and Australopithecus africanus and Australopithecus robustus were all key rungs in the development of humanity. These fossils were found in East and South Africa (Azania). Some of the fossils may be as old as 5 million years. For example Australopithecus robustus fossils found in an East Turkana Kenya site were at least 4 million year old.

It is generally accepted that the Homo habilis were the first full fledge tool making ancestor of humans. The earliest archaeological evidence of toolmaking comes from the Koobi Fora section of East Turkana. These Homo habilis are believed to be at least 2.5 million years old. The name Homo habilis comes from the Leakeys. They found what they believed to be conclusive fossil evidence of the first humans in the Olduvai Gorge in Tanzania and gave these ancestors that name called Homo habilis.. The Olduvai Gorge Homo habilis existed at least a million and quarter years ago

Our knowledge of prehistory derives from surviving objects - the evidence of archaeology. History, by contrast, is based on documents. These various interconnections mean that history, civilization and writing all begin at the same time. That time is about 3100 BC.



The categorization of the past into discrete, quantified named blocks of time is called periodization. This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (time periods in the origin and evolution of the universe), geological (time periods in the origin and evolution of the Earth), anthropological (time periods in the origin and evolution of humans) and historical (written history).

The ingredients of civilization

Many different elements must come together before a human community develops to the level of sophistication commonly referred to as civilization. The first is the existence of settlements classifiable as towns or cities. This requires food production to be efficient enough for a large minority of the community to be engaged in more specialized activities - such as the creation of imposing buildings or works of art, the practice of skilled warfare, and above all the administration of a centralized bureaucracy capable of running the machinery of state.

CASE 461 - The history of Greenland

CASE 461 - The history of Greenland



The history of Greenland is a history of life under extreme Arctic conditions: currently, an ice cap covers about 80 percent of the island, restricting human activity largely to the coasts. The first humans are thought to have arrived in Greenland around 2500 BC. Their descendants apparently died out and were succeeded by several other groups migrating from continental North America. There has been no evidence discovered that Greenland was known to Europeans until the 10th century, when Icelandic Vikings settled on its southwestern coast, which seems to have been uninhabited when they arrived. The ancestors of the Inuit Greenlanders who live there today appear to have migrated there later, around 1200 AD, from northwestern Greenland. While the Inuit survived in the icy world of the Little Ice Age, the early Norse settlements along the southwestern coast disappeared, leaving the Inuit as the only inhabitants of the island for several centuries. During this time, Denmark-Norway, apparently believing the Norse settlements had survived, continued to claim sovereignty over the island despite the lack of any contact between the Norse Greenlanders and their Scandinavian brethren. In 1721, aspiring to become a colonial power, Denmark-Norway sent a missionary expedition to Greenland with the stated aim of reinstating Christianity among descendants of the Norse Greenlanders who may have reverted to paganism. When the missionaries found no descendants of the Norse Greenlanders, they baptized the Inuit Greenlanders they found living there instead. Denmark-Norway then developed trading colonies along the coast and imposed a trade monopoly and other colonial privileges on the area.



During World War II, when Germany invaded Denmark, Greenlanders became socially and economically less connected to Denmark and more connected to the United States and Canada. After the war, Denmark resumed control of Greenland and in 1953 converted its status from colony to overseas amt (county). Although Greenland is still a part of the Kingdom of Denmark, it has enjoyed home rule since 1979. In 1985, the island decided to leave the European Union, which it had joined as a part of Denmark in 1973. From 1948 to 1950, the Greenland Commission studied the conditions on the island, seeking to address its isolation, unequal laws, and economic stagnation. In the end, the Royal Greenland Trading Department's monopolies were finally removed. In 1953, Greenland was raised from the status of colony to that of an autonomous province or constituent country of the Danish Realm. Despite its small population of 50000 to 55000 people, it was provided nominal representation in the Danish Folketing.



Greenland home rule

Greenland's minimal representation in the Folketing meant that despite 70.3% of Greenlanders rejecting entry into the European Common Market (EEC), it was pulled in along with Denmark in 1973. Fears that the customs union would allow foreign firms to compete and overfish its waters were quickly realized and the local parties began to push strongly for increased autonomy. The Folketing approved devolution in 1978 and the next year enacted home rule under a local Landsting. On 23 February 1982, a bare majority (53%) of Greenland's population voted to leave the EEC, a process which lasted until 1985. Greenland Home Rule has become increasingly Greenlandized, rejecting Danish and avoiding regional dialects to standardize the country under the language and culture of the Kalaallit (West Greenland Inuit). The capital Godthåb was renamed Nuuk in 1979; a local flag was adopted in 1985; the Danish KGH became the locally administered Kalaallit Niuerfiat (now KNI A/S) in 1986. Following a successful referendum on self-government in 2008, the local parliament's powers were expanded and Danish was removed as an official language in 2009.

International relations are now largely, but not entirely, also left to the discretion of the home rule government. After leaving the EEC, Greenland signed a special treaty with it, granting it special access to the market as a constituent country of Denmark, which remains a member. Greenland is also a member of several small organizations along with Iceland, the Faroes, and the Inuit populations of Canada and Russia. It was one of the founders of the environmental Arctic Council in 1996. The US military bases on the island remain a major issue, with some politicians pushing for renegotiation of the 1951 US–Denmark treaty by the Home Rule government. The 1999–2003 Commission on Self-Governance even proposed that Greenland should aim at Thule Air Base's removal from American authority and operation under the aegis of the United Nations.[

CASE 460 - The history of music - part 4 / The 1950's

CASE 460 - The history of music - part 4 / The 1950's



In the First World, rock and roll, doo-wop, pop, jazz, swing, rhythm and blues, blues, country and rockabilly dominated and defined the decade's music. Rock and roll dominated popular music in the later half of the 1950s. It evolved in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various black musical genres of the time, including rhythm and blues and gospel music; with country and western and Pop. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience and is credited with first using the phrase "rock and roll" to describe the music.

The 1950s saw the growth in popularity of the electric guitar (developed and popularized by Les Paul). Paul's hit records like "How High the Moon", and "The World Is Waiting for the Sunrise", helped lead to the development of a specifically rock and roll style of playing of such exponents as Chuck Berry, Link Wray, and Scotty Moore. Chuck Berry, who is considered to be one of the pioneers of Rock and roll music, refined and developed the major elements that made rock and roll distinctive, focusing on teen life and introducing guitar solos and showmanship that would be a major influence on subsequent rock music. Artists such as Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, Big Joe Turner, and Gene Vincent released the initial rhythm and blues-influenced early rock and roll hits. Rock and roll forerunners in the popular music field included Johnnie Ray, The Crew-Cuts, The Fontane Sisters, and Les Paul and Mary Ford. The Rock and Roll Era is generally dated from 25 March 1955 premiere of the motion picture, "The Blackboard Jungle". This film’s use of Bill Haley and His Comets' "(We’re Gonna) Rock Around the Clock" over its opening credits, caused a national sensation when teenagers started dancing in the aisles. Pat Boone became one of the most successful artists of the 50s with his heavily Pop-influenced "covers" of R&B hits like "Two Hearts, Two Kisses (Make One Love)", "Ain't That a Shame", and "At My Front Door (Crazy Little Mama)". Boone's traditional pop approach to rock and roll, coupled with his All-American, clean-cut image helped bring the new sound to a much wider audience. Elvis Presley, who began his career in the mid-1950s, soon became the leading figure of the newly popular sound of rock and roll with a series of network television appearances, motion pictures, and chart-topping records. His energized interpretations of songs, many from African American sources, and his uninhibited performance style made him enormously popular—and controversial during that period. Boone and Presley's styles/images represented opposite ends of the burgeoning musical form, which competed with one another throughout the remainder of the decade.

Rock & roll

Rock and roll dominated popular music in the later half of the 1950s. It evolved in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various black musical genres of the time, including rhythm and blues and gospel music; with country and western and Pop. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music. The 1950s saw the growth in popularity of the electric guitar (developed and popularized by Les Paul). Paul's hit records like "How High the Moon", and "The World Is Waiting for the Sunrise", helped lead to the development of a specifically rock and roll style of playing of such exponents as Chuck Berry, Link Wray, and Scotty Moore. Chuck Berry, who is considered to be one of the pioneers of Rock and roll music, refined and developed the major elements that made rock and roll distinctive, focusing on teen life and introducing guitar solos and showmanship that would be a major influence on subsequent rock music.

Classic pop

Popular music dominated the charts for the first half of the decade. Vocal-driven classic pop replaced big band/swing at the end of World War II, although it often used orchestras to back the vocalists. 1940s style Crooners vied with a new generation of big voiced singers, many drawing on Italian Canto Bella traditions. Mitch Miller, A&R man at the era's most successful label, Columbia Records, set the tone for the development of popular music well into the middle of the decade. Miller integrated country, Western, rhythm & blues, and folk music into the musical mainstream, by having many of his label's biggest artists record them in a style that corresponded to Pop traditions. Miller often employed novel and ear-catching arrangements featuring classical instruments (whooping french horns, harpsichord), or sound effects (whip cracks). He approached each record as a miniature story, often "casting" the vocalist according to type.

R&B

In 1951, Little Richard Penniman began recording for RCA Records in the late-1940s jump blues style of Joe Brown and Billy Wright. However, it wasn't until he prepared a demo in 1954, that caught the attention of Specialty Records, that the world would start to hear his new, uptempo, funky rhythm and blues that would catapult him to fame in 1955 and help define the sound of rock and roll. A rapid succession of rhythm-and-blues hits followed, beginning with "Tutti Frutti" and "Long Tall Sally", which would influence performers such as James Brown, Elvis Presley, and Otis Redding. At the urging of Leonard Chess at Chess Records, Chuck Berry had reworked a country fiddle tune with a long history, entitled "Ida Red". The resulting "Maybellene" was not only a #3 hit on the R&B charts in 1955, but also reached into the top 30 on the pop charts.

Stax Records was founded in 1957 as Satellite Records. The label was a major factor in the creation of the Southern soul and Memphis soul styles.

In 1959, two black-owned record labels, one of which would become hugely successful, made their debut: Sam Cooke's Sar, and Berry Gordy's Motown Records.

Blues

Ray Charles

Blues had a huge influence on mainstream American popular music in the 1950s with the enthusiastic playing styles of popular musicians like Bo Diddley and Chuck Berry, departed from the melancholy aspects of blues and influenced Rock and roll music. Ray Charles and Fats Domino help bring blues into the popular music scene. Domino provides a boogie-woogie style that heavily influences rock 'n' roll.

Country music

Country music stars in the early 1950s included Hank Williams, Patsy Cline, Bill Monroe, Eddy Arnold, Gene Autry, Tex Ritter, Jim Reeves, Tennessee Ernie Ford, Chet Atkins and Kitty Wells. Wells' 1952 hit "It Wasn't God Who Made Honky Tonk Angels" became the first single by a solo female artist to top the U.S. country charts. "It Wasn't God ... " was a landmark single in several ways; it began a trend of "answer" songs, or songs written and recorded in response to (or to counterpoint) a previously popular song – in this case, "The Wild Side of Life" by Hank Thompson – and for Wells, began a trend of female singers who defied the typical stereotype of being submissive to men and putting up with their oft-infidel ways, both in their personal lives and in their songs.

CASE 459 - The quantum age

CASE 459 - The quantum age



Quantum computing studies theoretical computation systems (quantum computers) that make direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. Quantum computers are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation is analog and uses quantum bits, which can be in an infinite number of superpositions of states. A quantum Turing machine is a theoretical model of such a computer, and is also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic and probabilistic computers. The field of quantum computing was initiated by the work of Paul Benioff and Yuri Manin in 1980, Richard Feynman in 1982,and David Deutsch in 1985. A quantum computer with spins as quantum bits was also formulated for use as a quantum space–time in 1968.



As of 2016, the development of actual quantum computers is still in its infancy, but experiments have been carried out in which quantum computational operations were executed on a very small number of quantum bits. Both practical and theoretical research continues, and many national governments, military agencies/companies and private companies such as D-wave, google, IBM are funding quantum computing research in an effort to develop quantum computers for civilian, business, trade, environmental and national security purposes, such as cryptonalysis. Large-scale quantum computers would theoretically be able to solve certain problems much quicker than any classical computers that use even the best currently known algorithms, like integer factorization using Shor's algorithm or the simulation of quantum many-body systems. There exist quantum algorithms, such as Simon's algorithm, that run faster than any possible probabilistic classical algorithm. Given sufficient computational resources, a classical computer could in theory simulate any quantum algorithm, as quantum computation does not violate the Church–Turing thesis.:202 On the other hand, quantum computers may be able to efficiently solve problems which are not practically feasible on classical computers.



Classical binary digital computers VS Quantum computers

Classical Computer is fashioned from semi-conductor material in printed circuits for the gate level logic which enables procedural languages to be written. In simple terms a classical computer is a state machine (Turing Machine) design to take input apply a set of rules and and produces an output 1 in 1 out. The classical computer takes digital data sequential instructions, the states (bits)



Quantum Computer is brought about by the landscape below where physical implementation of Quantum Architecture to the manifestation of quantum behaviour and collection of results and is able to process instructions stored in "quantum bits (qubits) which have the "feature" of processing all instruction data in parallel at the logic level.
