Free Essays on Star Dust

Star Dust Have you ever wondered how many different objects and particles enter earth’s atmosphere everyday. The earth is growing fatter under continuous microscopic flurry of space specks. The earth gathers 100 tons of space dust everyday. These space particles come from all the over the universe, from the asteroids in the asteroid belt to pieces of distant planets from the dust that was there when our planet was created. By studying these dust particles, astrophysicists say we can learn about our cosmic roots. Cosmic particles are all around us, however, it is near impossible to tell it apart from all the earthly particles in the air. Such things as pollen, pollution, soil, human skin, etc. Not only is space dust hard to see it’s even harder to catch, they are the size of 100 micrometers (Or the width of a hair). To collect space dust scientist have turned to Antarctica. Where there are little to known of earth’s floating particles. The Amundsen-Scott South Pole stat ion draws its drinking water from a well in a cavity of the never-ending ice. As the water is pumped up through a small hole on the surface, the water is heated and shot back down to melt more ice. As the ice melts, it frees the space particles that were in the snowflakes. There was a lot of build up of particles on the well floor. Studying these particles was as easy as throwing a bucket down a hole. Another way dust particles are collected is to attach sticky film to a high altitude aircraft. Once the Astrophysicist have captured the dust, they can determine how fast it entered the earth’s atmosphere thus telling us if it came from a comet, asteroids, or virginal stardust. The Astrophysicist determines the speed of the dust by putting the dust particle in an oven. They rise the temperature until the minerals in the dust particle start to evaporate. If the minerals evaporate at 901 degrees but not at 900 we know that the dust particle was heated to a ma...

How similar were the reasons f essays

How similar were the reasons f essays How similar were the reasons for the Hungarian uprising of 1956 and the events in Czechoslovakia in 1968 The uprising in Hungary originally began because of Khrushchevs Destalinisation policies. The Hungarian government had not implemented any of these reforms and the people began to protest. The Government was currently run by a man named Gero. His government could not handle the violence that was resulting from these protests, the soviet tanks were forced to retreat from Budapest and the pressure on Gero only grew. Eventually Gero was forced to leave his place of leadership because of pressure from the soviet government, he was replaced by Nagy; Nagy was a moderate communist and began to implement reforms. The events in Czechoslovakia began in very much the same way. The leader of the government at the time was Novonty, Novotny became leader in 1957. Novotny's government had refused to implement any reforms. This upset much of the public and those in the government who supported the reforms policy. In 1963 after many years of pressure from the public and reformists in the government Novotny finally resigned his position. Novotny was replaced By a more moderate communist Anthony Dubcek. Dubcek was also quite open to the idea of reforms and more freedoms for the people. These two situations are quite similar only the later Czechoslovakian rising did not feature many protests or violence. However both had the opposition to government and eventual resignation of hard line rulers replaced by moderate communists. The opposition to the attitudes of the Government was strongly felt but because of censorship policies could not be openly voiced. The resignation of Novotny took a lot longer than Gero because the people did not have violent protests or demonstrations. Having seen the riots and increasing violence of the Hungarians during the reign of Gero Nagy knew that he would have to offer a lot of reforms or at...

Baroque and Classical and the modern song Essay Example | Topics and Well Written Essays - 500 words

Baroque and Classical and the modern song - Essay Example â€Å"Black Star shows off the many facets of Yngwie’s singular style† (Walster 95). Yngwie writes following the musical theory’s rules and the Baroque counterpoint. A very good example of his style of writing is the song â€Å"Black Star† from his debut LP Rising Force, that reflected many examples of Baroque and classical writing. â€Å"Black Star† has a form that adjusts into the A B A C A B A, though the ending of the song is improvised in that the song does not get back to A after the second B section. Instead, the song reaches the end with the improvisation of C section. Numerous facets of Yngwie’s guitar playing reflect in the song â€Å"Black Star†. The song starts with a prelude that, in a way, is suggestive of Bouree of Bach in the E minor. The harmony becomes reminiscent of the standard chamber music when it comes in with guitars, though the fact that the song is played with the electric guitars brings in the difference. At the end of the passage, there is an exposition which employs the use of volume swelling along with an echo effect and volume knob that releases the sound like spiccato that is a technique of classical violin. The theme melody of the song â€Å"Black Star† is based upon a mode of E harmonic. The song proceeds toward the B key that is the dominant, and provides an example of yet another gesture of the Baroque-classical harmonic used by Yngwie. Yngwie plays the piece quite symmetrically that makes him mimic the classical violin. In addition to that, Yngwie played bass line in â€Å"Black Star†.
