History of Submarine

Many experts and scholars in the 16th century have started looking for forms and systems to make this underwater vehicles. Inspiration started from a boat or regular boat. Obvious relation, ships or boats gliding on the water. Some parts were in the water. Then the thought: "What if all parts of the ship can be in the water, but still able to glide and ride like a regular boat?!" Then with the help of science ideas to make the submarine appeared in 1578. William Bourne, a mathematician, designing a vessel covered by a water-resistant leather. This ship is meant to rowed in the water, because it was not yet known to the machine.

But this ship failed to realize. Similar ideas forwarded by the Germans in 1620. The author, Cornelis Drebbel, who managed to make a boat dive as deep as 360 to 450 centimeters, rowed by 12 people. Simple submarine without a paddle as well as more advanced equipment was started by a schoolboy d Yale (USA), David Bushnell. Submarine shaped like an egg creations, made of wood.

Equipment is the main breathing tube to the surface of the water, the propeller is rotated by hand labor, which manages the buoyancy tank and sinking submarines (if you want to dive, some water filled tank through a valve that can be set with legs raised upward and when water, the water is pumped out by hand), compass and a ballast in order to position the ship remains. Because the ship is then used for war, the ship is also equipped with torpedoes. Yet this new in 1775!?

Propulsion submarines with nonhuman started by Robert Fulton. It uses the steam engine to run the ship. And to facilitate the ship lurched forward, the vessel is made with a cigar shape. This cigar ship carrying 2 crew and was able to dive a few hours. More advanced submarines again belongs to the U.S. Navy in 1900. PG creator named John Holland and his ship called Holland. 1,590 centimeters long ship, run by a gasoline engine and electric power. Because it is a part of military equipment, ships equipped with weapons, including torpedoes, with a burst of air pressure.

But in use, gasoline often endanger the ship itself. Then to overcome this problem, devised a machine with a safer fuel, ie diesel, the diesel engine. This happened in 1905 and is a British vanguard. The diesel-powered submarine later became bakuan subsequent submarines. Right now there are powered submarines until 1000-1600 horsepower on diesel.

After the 2nd World War (P2D), equipment and advanced submarine capabilities even further. In the war-for example-and the U.S. Navy submarines also use a type of diesel engines Fleet. Their submarine 90 meters in length, with a crew of 85 people, speed 20 knots in 10 knots on the water and in the water, 10 pieces of the barrel torpedo mounted on the front and back of the ship, with the ability to release 24 per barrel torpedo. Each contains about 250 kiligram torpedo explosives. The actual speed of the submarine could reach 45 knots, but for security reasons the ship itself, the speed used only 20 knots. With this speed torpedo can be thrown with a speed of 29 knots.

U.S. defense even more to show sea power more firmly. In 1954, AL-United States made history, by launching its first nuclear-powered submarine, called the Nautilus. In the same year all peak capacity and speed submarine subverted by it. Submarine Nautilus became the first vessel to cross the North Pole in 1958. There are other peaks that were made, but by other submarines named Triton. 1960 Triton managed to wade through all the oceans of the world under water. This ship and wade across 66,970 kilometers in 84 days. Not only that, in 1960 the United States have started to equip their submarines with missiles (missile) intercontinental. The ballistic missile could pass 1,930 yards and destroy the targeted country.

But not the U.S. alone that have nuclear submarines. Soviets also had. Even according to military experts the world, the Soviet submarine fleet has more. Soviet submarines had about 350, with about 60 submarines armed with ballistic missiles. The U.S. only has 135 ships including 40 submarines armed with ballistic missiles. They both did handyman war, so it must have a lot of armaments.

Other countries are more peaceful certainly have less equipment. For example Indonesia, which only has 4 subs, 2 and 2 artificial Soviet-made West Germany. Which earlier was named Pasopati and Bramastra, the latter being Nanggala and Chakra.

History of Bluetooth

Bluetooth is the industry specification for personal area network (PAN or personal area networks) without wires. Bluetooth connects and can be used to exchange information between devices. Spesifiksi of Bluetooth devices is developed and distributed by the Bluetooth Special Interest Group. Bluetooth operates in the 2.4 GHz frequency band using a frequency hopping traceiver capable of providing voice and data communication services in real time between hosts with distance space. weakness bluetooth technology is a short range and low data transfer capabilities.

The presence of bluetooth makes a person no longer troubled with what cable, what color, to get to where, and where to plug into.  interconnection function can be replaced by a Bluetooth chipset that is placed on a built-in electronic equipment related.

The name "Bluetooth" is derived from the name of the king at the end of ten centuries, Harald Blatand that in England also called Harald Bluetooth. Thus the connotation is not far wrong, because according to mythology, it is said Bluetooth-haired and dark-skinned. He likes to eat blueberries or strawberries, it's worth it when Blatand teeth into a bluish or blue tooth.

He is the king of Denmark who has managed to unite the tribes that previously fought, including parts of what is now Norway and Sweden. Even the Scania region in Sweden, where Bluetooth technology is found also included his territory. Capabilities as a unifying king was also similar to the bluetooth technology now that can connect a variety of devices such as personal computers and mobile phones. While the Bluetooth logo come from the union of two German letters are analogous with the letter H and B (short for Harald Bluetooth), namely H (Hagall) and Runic letter (Blatand) which are then combined.

The beginning of Bluetooth is a wireless communication technology (without cable) which operates in the frequency band 2.4 GHz unlicensed ISM (Industrial, Scientific and Medical) using a frequency hopping transceiver capable of providing voice and data communication services in real-time between bluetooth host-host with limited service reach distance (about 10 meters).

Bluetooth A card that uses radio frequencies to the IEEE 802.11 standard limited range of services and the ability to transfer data is lower than cards for Wireless Local Area Network (WLAN). Bluetooth formation promoted by 5 large companies Ericsson, IBM, Intel, Nokia and Toshiba formed a Special Interest Group (SIG) is launching this project. In July 1999 document bluetooth specification version 1.0 was launched.

In December 1999 started again making bluetooth specification document version 2.0 with the addition of 4 new promoters namely 3Com, Lucent Technologies, Microsoft and Motorola. Currently, more than 1800 companies in various fields join a consortium as bluetooth technology adopter. Although standard Bluetooth SIG is now 'owned' by the promoter group, but he is expected to become an IEEE standard (802.15).

Currently more than 2,000 companies or community members joined the SIG bluetooth lovers. With bluetooth they offer more value in their products to target customers market top. In the next 2-3 years, bluetooth certain to be mass produced and integrated into a variety of office equipment products, household, health, medical equipment, automotive, music, games, and entertainment. Bluetooth will drastically change the lifestyle and way of working of office equipment and household utensils

History of Cowboy Hats

John Batterson Stetson was an American who was born in Orange, New Jersey in 1830. Up to now the Stetson name attached as part of the term "the real Stetson hat" or general we are familiar with the cowboy hat.

Beginning Stetson hat shape is strange or unusual, even often used as a joke of his colleagues. But gradually the Stetson hat proves that being very useful. Wide side serves as a protection against rain water, then in times of hot weather, there is an air bag on the top end cap that provides insulation against the Stetson head, so that the temperature inside the hat to stay cool. Even the head of the Stetson hat (crown head) can be used for drinking water.

Based on stories told from generation to generation, the first to use cowboy Stetson hat redeem it for 5 dollars in gold. At that time the cowboy met with John Stetson on a journey, the Stetson cowboy hats are interested in and decided to buy it.

In 1865, John B. Stetson decided to end the adventure "wild-wild west it" and settled in Philadelphia, Pennsylvania. Stetson then set up a production house outdoor hat with a model that he found the first time (cowboy hat, cowboy hat). His first model was officially named "Boss of the Plains". In 1886, Stetson hat company has become the largest in the world and in 1906, the company has produced 2 million cowboy hats. Until now the basic model and the way of making a Stetson cowboy hat has not changed much since it was first produced in 1865. Stetson then attached with legend world "Wild West" as Buffalo Bill, Calamity Jane, Billy the Kid, Will Rogers even Lucky Luke.

History of Reggae Music

In 1968 many years known as the birth of reggae music. Actually there is no specific incident that became a marker early history, except transitional musical taste of Ska and Jamaican society Rock steady, which was popular among the young in the first half until the end of the 1960s, the new musical rhythm slower tempo: reggae. Perhaps frenetic and fast tempo Ska and Rock steady less wear to the social and economic conditions in Jamaica are stressful.

History of Reggae Music in the World

The word "reggae" is supposedly derived from the pronunciation of the African accent of the word "ragged" (clumsy motion-like bodies pounding on people who dance to the music ska or reggae). Rhythm of reggae music itself influenced elements of R & B music that was born in New Orleans, Soul, Rock, rhythmic Afro-Caribean (Calypso, Merengue, Rhumba) and called Jamaican folk music Mento, rich with African rhythms. Musical rhythm that many considered to be a precursor to reggae is ska and rocksteady, the form of R & B musical interpretation that developed in Jamaica is loaded with the influence of Afro-American music. Technical and musical exploration conducted many Ska musicians, including shaking the guitar in reverse (up-strokes), putting pressure on a weak tone tone (syncopated) and multi-rhythmic drum beats are complex.

Engineering and Rocsteady Ska musicians in playing a musical instrument, imitated by many reggae musicians. However much slower tempo music with pounding bass and rhythm guitar is more prominent. Vocals are heavy with songs like pattern praises (chant), which influenced the rhythm of drumming, singing and mystical ways of Rastafari. Slower tempo of the music, in time to support the delivery of messages through the lyrics of songs associated with the Rastafari religious traditions and socio-political problems of humanistic and universal.

Album "Catch A Fire" (1972) which launched Bob Marley and The Wailers quickly catapulted to the outside of Jamaica reggae. Popularity of reggae in the United States supported also by the film The Harder They Come (1973) and reggae rhythms played by white musicians such as Eric Clapton, Paul Simon, Lee 'Scratch' Perry and UB40. Reggae rhythm was then affect streams music in the decade after that, call it a variant of reggae hip hop, reggae rock, blues, and so on.


Jamaica

Musical roots reggae is closely related to the land which gave it birth: Jamaica. When discovered by Columbus in the 15th century, Jamaica is an island inhabited by Arawak Indians. Jamaica name itself comes from the Arawak vocabulary "Xaymaca" meaning "island of forests and water". Spanish and British colonialism in the 16th century destroyed the Arawak tribe, who was later replaced by a black bondsman thousands of African mainland. Slaves were employed in the sugar industry and plantations are scattered there. The dark history of oppression between humans began and lasted until more than two centuries. New in 1838 removed the practice of slavery, which is followed by the world sugar trade slowdown.

In the midst of heavy work and the threat of oppression, the African slaves maintain attachment to their homeland with the tradition. They narrate life in Africa with the song (chant) and sounds (drumming) is simple. Interaction with the employers who came from Europe were membekaskan cross-cultural product that eventually became the original Jamaican folk tradition. When the black community in America or Europe with their African identity fade quickly, otherwise black communities Jamaica still feel the closeness with ancestral lands.

Reggae music itself was originally born from the streets Getho (Rastafaria the township) in the Jamaican capital Kingson. This is what causes hair styles dreadlocks adorning the early reggae musician and song lyrics reggae rastafari teachings loaded with cargo that is freedom, peace, and beauty of nature, and the bohemian lifestyle. Inclusion as one of the reggae world music elements that also affect many other musicians world, automatically result in the flow of the music is a world of public consumption goods. Thus, dreadlocks or dreadlock hair style as well as the lyrics 'rasta' in his song became public consumption. In other words, dreadlock rasta and teachings have become pop production, to pop culture, as the development of reggae music as a pop music.

Reggae, rastaman title, has become a new form of subculture in this country, where her youth define and classify herself. Here, reggae music became important as a taste, and rastaman became a communal identity of a particular social group. Just how social observers and also the members of the community to understand themselves and the culture they choose, in order to avoid distortions harmful to them. The use of marijuana is one such example, where reggae is not synonymous with marijuana and rastafarianisme was not a community of marijuana.

A song from "Peter Tosh" (real name Peter McIntosh), frontman of The Wairles who eventually pursue a solo career. In this song, Peter Tosh and demands expressed support for legalizing marijuana. Because of this song, he was arrested and tortured by the police Jamaica.

According to the history of Jamaica, the slaves brought drums from Africa called "Burru" arrangements which become part of a song called "talking drums" (talking drum) which is native from West Africa. "Jonkanoo" music culture is a mixture of African, European and Jamaica consisting of drumming, rattle (musical instrument creaking) and conch blowing. This event occurs when Christmas comes masked dancers.

Jonkanoos originally a dance of the peasants, who only realized later that they actually communicate with the drums and conch. The next year, Calypso from Trinidad & Tobago came with Samba that comes from Central America and was introduced to the people - people of Jamaica to form a new blend called Mento. Mento music itself is simple with humorous lyrics accompanied by guitar, banjo, tambourine, shaker, scraper and rumba, or the bass.

This form then popular in the 20 and 30s and is a form of Jamaican music that first attracted the attention of the whole island. Currently Mento can still be enjoyed serving tourism. SKA has appeared in 40 - 50s actually mentioned by the History of Jamaican Music, impacted by Swing, Rythym & Blues of the United States. SKA is actually the sound of the big band horn arrangements (wind instruments), piano, and a quick tap "bop". Ska then easily switch and produce a form of dance "Skankin" pad early 60s.

Of early Jamaica, among others, Byron Lee and the Dragonaires formed in 1956 which was then regarded as the creator of "ska". Ska developments which then slowed the tempo in the mid 60s led to "Rock Steady" a bass heavy tune punta and popularized by Leroy Sibbles of the Heptones and the group became the first Jamaican dance music in the 60s.

"Reggae & Rasta"

Bob Marley of course, is the music star "third world" so the first group singer Bob Marley & The Wailers and reggae successfully introduced more universal. Nonetheless, reggae regarded by many as a relic of King of Reggae Music, Hon. Robert Nesta Marley. Coupled with the presence of "The Harder They Come" in 1973, added Reggae known to many people.

The death of Bob Marley then it brings great sadness for the world, but his successors such as Freddie McGregor, Dennis Brown, Garnett Silk, Marcia Fiffths and Rita Marley and Marley sprung some relatives. Rasta Reggae music is clear shaper is used as a weapon by Bob Marley Rasta to spread throughout the world.

This incredible music that grew from ska to American style elements of R & B and Caribbean. Some opinions state also influences: folk music, church music Pocomania, jonkanoo Band, ceremonies - ceremonies farmers, planting work songs, and mento form.

Nyahbingi is the most natural form of music that is often played at the meeting - the meeting Rasta, using 3 hand drums (bass, funde and repeaters: there are examples in the Mystic Revelation of Rastafari). Roots reggae itself always explore the theme of suffering forced labor (ghetto dweller), slaves in Babylon, Haile Selassie (the human kind god) and hope the return of Africa. Jamaica after independence in 1962, poor governance and the development of the Black Power movement in the U.S. then encouraged the rise of Rasta. Monumentalpun events occurred over this development.


"What the heck Reggae"

Reggae itself is a combination of African traditional accompaniment, American and Blues and folk (folk song) Jamaica. The synthesis of style clearly demonstrate the authenticity of Jamaica and put a knock broke - broke apart, strumming the guitar upwards, vocal patterns that 'preaching' and the lyrics are still about Rastafari religious traditions. Although many commercial benefits that have been derived from reggae, Babylon (Jamaica), strict government often considered to restrict the movement but not the political aspect Rastafarinya. "Reg-ay" arguably arises from the notion that reggae is a style of Jamaican music is based on American soul music, but with a rhythm that 'behind' and the fabric of a prominent bass. The theme weve often about Rastafari, political protest, and rudie (hooligan hero). Existing forms (ska and rocksteady) seem to be more powerful influence of African music - despite his American guitar playing also fill 'hole - hole' empty and drum accompaniment complex. In contemporary reggae, ritual drumming taken from Rastafarian who tend mystical and sacred, because it will be more calm tempo and focuses on issues of social, political and humane message.

"Not authentic Jamaican"

Reggae music is indeed unique to Jamaica, ironically roots originating from New Orleans R & B. Closest ancestor, ska originated from New Orleans R & B Jamaican musicians heard on radio broadcasts Amrik through their transistor radios. With reference to the accompaniment of the guitar fit - barely and broken - their interpretation will be R & B and capable so popular in the 60s. Furthermore during the hot summer, they also must be hot if playing ska plus dance, song results slowed and Reggae was born. Since then, Reggae Blues proved to be as strong and powerful interpretation could also borrow from Rocksteady (first) and even rock music (now). African music is essentially there in everyday life, be it on the street, bus, public places, workplaces ato house so kind of spirit when difficult conditions and capable of providing power and message of its own. The result, Reggae music not only provide relaxation, but it also carries a message of love, peace, unity and balance and be able to loosen the tension.
