Pluto Essays - Planetary Science, Pluto, Neptune, Ice Planet

Pluto Pluto repeats an anomaly when compared with the terrestrial planets (Mercury, Venus, the Earth and Mars) or the giant planets (Jupiter, Saturn, Uranus and Neptune). This icy world is more like a huge asteroid or the satellites of the outer planets; it has even been suggested that Pluto was a satellite that escaped from Neptune's pull. The small size of Pluto combined with its distance make it very difficult to observe; however, two important discoveries have just been made. In 1976 new spectroscopic observations revealed that the surface of Pluto was covered, at least partially, by frozen methane. The infrared spectrum enabled this methane to be identified, besides other kinds of ice, such as ice of ammonia or water. The surface of Pluto, covered by ice, is therefore bright and its reflective power (or albedo) is much greater than we would suppose, thinking that it was all covered by rocks. Knowing its distance from the Earth and its reflection coefficient we can deduce a diameter of between 2000 and 2700 kilometers; its mass is thus much less than first estimates.

The racial segregation in America is a social phenomenon that no one would like to experience, it should elicit bad memories in any individual, but the persona simply says,† †¦.he laughs.† He seems to be unaffected by the racial discrimination that he is being subjected to, he simply dismisses it, ev en though we all know that such occurrences would make an individual bulge and assume a combatant attitude.(Rhynes 62) Patriotism Conventionally, anyone who gets treated wrongfully in an environment will be conditioned to deeply loathe such environment. A student battered in any high school will hate anything to do with high schools, despite the sub human treatment he gets from the fellow countrymen; he is still patriotic enough to proclaim his love for the same nation. In the last line, he claims authoritatively that â€Å"†¦I too am America.† He loves his country despite the ill treatment he is invariantly subjected to.Advertising Looking for essay on biography?

In my opinion, it forms the primary trait of the persona. The author wanted to illuminate a ray of hope to the vic tims of racial segregation. He outlines this throughout the poem. When he says that he eats and grows strong, the value of hope is portrayed, he is not easily broken disheartened, he looks forward for change, and so he says, â€Å"†¦Tomorrow, i will be at the table.† A hopeful person quotes the future, while a hopeless person drowns in disillusionment. (Rhynes 102) The persona however, looks forward for the brighter tomorrow. From the tone of the poem, it is very obvious that the future that he is waiting for will be much better than the present time. (Rhynes 11) He argues that his tormentors â€Å"will see how beautiful I am.† Use of â€Å"will† infers to a future tense meaning the persona is still keeping hope alive of better tomorrow. (Rhynes 64) The calmness he portrays in the poem is due to his hope for a free America. (Rhynes 66) Patience The persona is a very tolerant person. He is not belligerent at all, even though it is obvious that he is subjecte d to surly conditions that undermine human dignity, he remains friendly to them, no wonder he says that â€Å"I laugh.† He also waits patiently for the outcomes of the future when he will be stronger and even â€Å"more beautiful.† Calmness and Tactfulness One would expect opposition from the persona to counter the oppressors, but he avoided the confrontation and instead remained calm. (Rhynes 33) He says that when sent to the kitchen, â€Å"he ate well†, he didn’t confront anybody but planned by eating well and â€Å"growing strong.† Eventually, he says that he’ll no longer be told to â€Å"eat in the kitchen,†Advertising We will write a custom essay sample on Langston Hughes Biography specifically for you for only $16.05 $11/page Learn More Rhynes, Martha E.I, too, sing America: the story of Langston Hughes.

American Empire, Oil and Global domination (The American Empire Essay

American Empire, Oil and Global domination (The American Empire Project) - Essay Example However, every time America had a solid argument which it presented to the world and made it appear to everyone that America's involvement is imperative either for its own security and defense or for the betterment of this world as a whole, let alone the consideration for devastations it brings to the world and innocent people on whom the war either declared or undeclared is imposed. The question that is raised by the world is that is it necessary for America to harm others in order to maintain its peace and security, or behind such arguments US is nurturing and fostering the concept of maintaining the US power and dominance over the world by controlling the world oil reserves and influencing the major oil producing countries. This paper exposes the arguments presented by United States for its invasion in Iraq, highlights the concept of American Empire with a background to reasons behind the major wars it has participated in and finally envisions the real behind the scene reasons and causes for the Iraq invasion. According to Burbach, Roger and Jim Turbell "Concentrating on terrorism for electionprovided an opportunity to highlight Bush's War on Terror and the need for patriotic Americans to rally behind the flag to support their President.Unfortunately, Osama Bin Laden, the terrorist who had rained fear down on America on 9/11, could not be found. They needed to find a new terrorist to portray as evil incarnate. Saddam Hussein fitted the bill."1 Iraq war was not only about Saddam Hussein, it was much about oil and control over the Middle East region. Middle East is the heart of world oil production where exists huge oil and energy reserves that are imperative for United State's well-being. According to Kofi Annan the UN Secretary General, there were no justifications for the use of military action against the Iraq.2 Iraq was not at all a threat to the Unites State's national security. Infact, United States had plans to invade Iraq for oil reserves even several months before the attack of September 11. According to Sunday Herald, the United States promoted the use of military action against Iraq about five months before the September 11 attack in order to control its secured oil supply in future.3 United States had already realized its ever increasing demand and declining supply for oil and it had already planned to invade Iraq which was the second largest supplier of oil to the world, about which Everest said, "Overthrowing Saddam Hussein, creating a client state in Iraq, and opening up Iraq's economy are key components of a much larger, multi-faceted global agenda in which energy resources play a crucial role"4 The event provided United States a great chance to set its foot in countries having huge energy reserves that was the only way to control the world oil supply and reserve a continued secured supply of oil for itself all behind the mask of national security and self-defense. However, the United States has always denied that its invasion of Iraq was for the purpose of imperialism and global dominance by means of controlling Iraq's discovered and undiscovered precious oil reserves, yet it is evident to the world that the real agenda behind the Iraq invasion was Oil, not the issue of American national security.
