Saturn
Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky (“Astronomy for Kids”). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer II traveled to Saturn in September of 1979, the Voyager missions took place in the 1980’s and the Cassini probe began it’s voyage in October of 1997 (Kuhn 280-282). There are many aspects of Saturn that make it one of the most extraordinary planets in this solar system.
Galileo Galilei was the first to view Saturn’s system of rings in the year 1610. Because he happened to be viewing their edge, he failed to recognize them as rings. In fact, he mistakenly interpreted the rings to be two moons similar to those he had discovered near the planet Jupiter. In 1655, a Dutch astronomer named Christiaan Huygens was able to discern what Galileo had thought to be moons as rings. Huygens benefited from a much improved telescope than that used by Galileo. A second moon of Saturn called Iapetus was found by the Italian astronomer Cassini in 1671. He also discovered, in 1675, that Saturn had more than one ring, i.e. a concentric pair of rings. A third ring was discovered by Johann Franz Encke in 1837 using a telescope at the Berlin observatory. Until Pioneer II approached Saturn in September of 1979, the planet was thought to have but three rings (Yenne 125).
Saturn is the sixth planet in the solar system, located between Jupiter and Uranus. Its average distance from the Sun is over 850 million miles, compared to Earth’s which is 93 million miles. Saturn’s orbit, the path it follows around the Sun, is nearly a circle. The closest the planet has come to the Sun is around 840 million miles, while the furthest away it gets is 930 million miles. Since Saturn is so far away from the Sun, it takes a very long time for it to complete its orbit of the Sun. Sa...

... and its moons in August 1981. The Cassini probe is exploring many of Saturn’s characteristics from its icy rings to the magnetic field, which is a very ambitious mission. The mission also entails the first decent of a probe to a moon of another planet - the most distant landing ever attempted on another object in the solar system (“Great Space Place”). These discoveries and close-ups of the exquisite characteristics of Saturn are what make this planet the most interesting and amazing of the solar system.

In Swift’s satirical essay he stated the main issue to be the hunger and starvation of Irish country and their lack of money to support oneself. He said the complication was they themselves don’t have food, to many families in poverty, and that the Englishman took their land and charging high prices for rent. Swift makes this argument because he too is an Irish men and he struggles to see his fellow men parish in the streets. He desires his people to stand up against England and take back what’s theirs. He argues that the Irish...
Swift's message to the English government in "A Modest Proposal" deals with the disgusting state of the English-Irish common people. Swift, as the narrator expresses pity for the poor and oppressed, while maintaining his social status far above them. The poor and oppressed that he refers to are Catholics, peasants, and the poor homeless men, women, and children of the kingdom. This is what Swift is trying to make the English government, in particular the Parliament aware of; the great socioeconomic distance between the increasing number of peasants and the aristocracy, and the effects thereof. Swift conveys his message in a brilliant essay, in which he uses satire, humor and shock value.
The kingdom rose to power and used its resources to become wealthy and prominent. Mali used its central trading location and surplus of valuable goods such as gold, salt, and copper to become the strongest and most powerful trading nation in Africa and Southern Europe. The nation had a strong leader in Mansa Musa who brought order, the Islamic faith, great economics, and an emphasis of scholarship to Mali, all of which were crucial to the country's success. Mali became an Islamic nation which brought a sense of togetherness for the citizens of Mali but gave Mali strong ties with other Islamic Nations. This togetherness helped Mali obtain peace and civility and helped in diplomacy. Mali’s Military also served as valuable asset in its rise to power. The army protected trade routes, helped keep peace and order in the country, expanded its borders and secured tribute from other countries. Mali’s success as a nation can be attributed to many different factors all of which were crucial in the development of the empire. Mali rose to great heights and flourished as nation. Their success should be respected and admired by
During the 1720’s, the Irish people were suffering dearly, due to the oppression by Great Britain. There oppression came in the form of being displaced by wealthy English people who were buying up land in Ireland and then not living there. They would proceed to rent some of their land to the Irish people at extremely high rent, which eventually led to them not being able to pay neither their rent or provide their families with food or clothes. The reason behind Swift’s proposal is simple. He is an Irishman. He has a sense of patriotic duty to attempt to help his fellow Irish people. He wants them to know that it is possible to move forward form poverty and out from under the oppression of the British. He structures his essay through a basic form of presenting an idea and then backing it up with “facts” like the growth in weight of babies or expert accounts on the taste of children from a credible source. Something that Swift just assumes that the audience will take for granted. Additionally he assumes that the audience won’t simply put his article down, taking it as the ramblings of a mad man talking about eating babies like it’s a normal everyday thing.
As I have described in The Lost Worlds of 2001, both projects proceeded simultaneously, with feedback in each direction. Thus I often had the strange experience of revising the manuscript after viewing rushes based upon an earlier version of the story - a stimulating but rather expensive way of writing a novel. As a result, there is a much closer parallel between book and movie than is usually the case, but there is also major differences. In the novel, the destination of the spaceship Discovery was Iapetus (or Japetus), most enigmatic of Saturn's many moons. The Saturnian system was reached via Jupiter: Discovery made a close approach to the giant planet, using its enormous gravitational field to produce a "slingshot" effect and to accelerate it along the second lap of its journey. Exactly the same maneuver was used by the Voyager space-probes in 1979, when they made the first detailed reconnaissance of the outer
There was also a great city in Mali called Timbuktu. It was very important because it was a center for trade and it aided the Muslim art and culture which helped to spread Islam.
Uranus is so far away that scientists knew comparatively little about it before NASA's Voyager 2 undertook its historic first encounter with the planet. The spacecraft flew closely past distant Uranus, and came within 81,500 kilometers (50,600 miles) of Uranus's cloudtops on Jan. 24, 1986. Voyager 2 radioed thousands of images and mass amounts of other scientific data about Uranus, its moons, rings, atmosphere, interior and magnetic environment. However, while Voyager has revealed much about the gas giant, many questions remain to be answered.
Throughout A Modest Proposal Swift uses verbal irony, diction, and sentence structure to achieve his purpose. His purpose of calling attention to all the terrible things England has done to Ireland is clearly stated throughout A Modest Proposal with the help of these three devices. His purpose of drawing attention to the problems throughout society has been described through A Modest Proposal. The dire poverty in Ireland is clearly expressed in the satire A Modest Proposal by Jonathan Swift.
If Jonathan Swift had written a serious piece simply espousing his true beliefs he would not have received as much feedback, due to the fact that there were already informational advertisements at the time and nobody was interested in reading them. The only thing that would get the people 's attention was something that would create a lasting impression, so he wrote a satirical piece with trenchant humor and mochary. “A Modest Proposal” surprised people and got them thinking about the condition of the poor in Ireland and what should be done to solve it. For example Swift states that “those who are thrifty” can use the carcass of the infant for ladies’ gloves or gentlemen’s boots. This itself can help those reading the piece to begin to think about possible solutions to the substantial issues involving the poor in Ireland. He also proposes that children that are fourteen should be consumed as well so the poor don’t have to go hungry and that it would limit the number of breeders, in an attempt to illustrate the extremity of the circumstances. His sarcastic way of joking enlisted fear in the poor and concern in the rich, helping them realise the drastic issue present in the
In 1729, Jonathan Swift published a pamphlet called “A Modest Proposal”. It is a satirical piece that described a radical and humorous proposal to a very serious problem. The problem Swift was attacking was the poverty and state of destitution that Ireland was in at the time. Swift wanted to bring attention to the seriousness of the problem and does so by satirically proposing to eat the babies of poor families in order to rid Ireland of poverty. Clearly, this proposal is not to be taken seriously, but merely to prompt others to work to better the state of the nation. Swift hoped to reach not only the people of Ireland who he was calling to action, but the British, who were oppressing the poor. He writes with contempt for those who are oppressing the Irish and also dissatisfaction with the people in Ireland themselves to be oppressed.
The Kingdom of Mali was an African hub of wealth, trade and education for over 225 years. Mali is an Arab version of the Mandinka word that means, “Where the king dwells”, and was vitally important in spreading trade, education, religion and culture along the Niger River. The rise of Mali into an Empire occurred in the early 13th century, when Sundiata defeated his enemies and won control of the West African gold mines. In 1312 Mansa Musa became ruler of Mali. During his reign which was known as Mali’s, “Golden Age”, he introduced Islamic beliefs to many communities along the Niger and enhanced education after his historic pilgrimage to Mecca. Mali’s rise was attributed to the Trans-Saharan Trade routes leading to and from Western and Eastern Africa. These trade routes contributed to the rise and fall of powerful African Kingdoms for hundreds of years, but for 250 years, Mali was the crown jewel of Africa.
In the short story “A Rose for Emily” written by William Faulkner, Emily, the protagonist, is shown as someone who’s life is falling apart and brought down by society. Emily in this story could be described as a victim to society and her father. Emily Grierson’s confinement, loss of her father and Homer, and constant criticism caused her, her insanity.
Miss Emily’s isolation is able to benefit her as well. She has the entire town believing she is a frail and weak woman, but she is very strong indeed. Everyone is convinced that she could not even hurt a fly, but instead she is capable a horrible crime, murder. Miss Emily’s actions range from eccentric to absurd. After the death of her father, and the estrangement from the Yankee, Homer Barron, she becomes reclusive and introverted. The reader can find that Miss Emily did what was necessary to keep her secret from the town. “Already we knew that there was one room in that region above stairs which no one had seen in forty years” (247).
...erprivileged mothers who strive to take care of their children but do not have the resources to do so. Lastly, Swift states that for want of work, the children of the impoverished Irish “either turn thieves, or leave their dear native country, to fight for the Pretender in Spain, or sell themselves to Barbados.” Swift makes the reader feel sympathy towards the impoverished children who are forced to make a living for themselves by any means necessary at a young age. Swift’s use of gripping word choice to describe the living conditions of the impoverished Irish effectively puts both emphasis and pity on their situation while also making the reader despise those who do not care about the poor.
