The Metamorphosis Essay Example | Topics and Well Written Essays - 500 words - 1

The Metamorphosis - Essay Example He is motivated by his need to fit into the role of being a family man. However, once Gregor is inexplicably transformed into an Ungeziefer— which is roughly equivalent to â€Å"vermin†Ã¢â‚¬â€ he is no longer capable of taking care of his family in a traditional capacity. Instead, he is relegated to being a blind, wilting creature. All of his energy goes towards looking out the window, even as his vision and perception deteriorate. He devolves from desiring to care for his family and retain his job to desiring nothing more than to delude himself into believing that his sister is playing the violin for him. He scurries out into their midst, no longer conscious as his familys need for him to remain hidden. He confronts his mother with his shriveled form and terrifies their lodgers with his uncleanliness. Ultimately, Gergors nature as a man is completely destroyed. As his family —however horrid they might be— points out, â€Å"If [this creature] were Gregor he would have seen long ago that its not possible for human beings to live with an animal like that and he would have gone of his own free will.† Gregor has lost his ability to place his family above himself, but he still retains his ability to feel affection as evidenced by the â€Å"emotion and love† he holds for his family. The obligation that he held as a traveling salesman, however, has long since faded away, taking with it the satisfactions and desires that mark him as

Napoleon Bonaparte Essay -- essays research papers

Napoleon Bonaparte Corsica is a rugged island in the Mediterranean, which lies sixty miles off the coast of Italy. The Corsicans are proud and independent people. In 1768, when the French took over the island from Genoa, an Italian state, the Corsicans rebelled and fought for their freedom. But they were unsuccessful. Their leader, Pasquale Paoli, was driven into exile. Several months later, on August 15, 1769, Napoleon Bonaparte was born in Ajaccio, a major port on the island. He was the second-born son of the family. His real name was Napoleone Buonaparte, but as a young man, he decided to give his name a French spelling. He did this because he had his mind set on a military career in France, and he didn’t want his Italian-sounding name to stop his progress. In 1796, he changed it permanently to Napoleon Bonaparte. When Napoleon was nine, his father decided he should go to school in France to get an education befitting their birth. But he didn’t have the money to pay for his schooling. He petitioned the king, Louis XIV, for a scholarship for Napoleon. The king had set up a special fund for the sons of French nobles, granting them money to attend military school. Now that Corsica belonged to France, the Bonapartes were French citizens and were eligible for this scholarship. Napoleon was excited about his future. Still, he was apprehensive. He had never left the island before, and he didn’t know how to speak French. So before he could further his training, he would have to learn the language. To do this his parents were sending him first to a school in Autun in southern France. There the students were mean, they had laughed at his Corsican accent and mocked his poor clothes and rough manners. When Napoleon had learned to speak French fluently, he went to study at Brienne, it a training school for the Military College in Paris. He found that the students there were even crueler. They looked down on him because he was of Corsican nobility. Taunting Napoleon, they called him a "slave" because his home had been conquered by the French. Napoleon was very sensitive. He withdrew more and more into himself. Soon he stopped trying to make friends. In a corner of the school yard, he set up a private garden, which he closed off with a wooden fence. One of its stakes he nailed a sign that read "Napoleon’s Country". He spent his days there,... ...he day wore on, neither side achieving a clear victory. However, the Prussians, who had managed to regroup their forces, came to the rescue of their allies. After they swarm into the battle, Napoleon’s attempt to reclaim the throne became known as The Hundred Days, ending with his great defeat at Waterloo. On June 22,1815, Napoleon was again forced to abdicate. Aware that the allies would be much harsher in their terms this time, he tried to escape to the United States. Napoleon hoped to get to America by booking passage on a merchant ship out of the French port of Rochefort, on the Atlantic. Napoleon secretly fled to Rochefort, but when he arrived in the town, he learned that the British were blocking the port and wouldn’t let any ship sail without first inspecting it to make sure he wasn’t aboard. On July 14, 1815, he decided to surrender to the British authorities. And he was being exile to St. Helena, a remote island lost in the South Atlantic. After nearly six years of lonely exile, Napoleon died on May 5, 1821, of stomach cancer at the age of 51. He was buried on St. Helena. Twenty years later, however, the British allowed his remains to be brought back to Paris, in state.

Newton Weights Essay

As it is known, different materials have different properties. They act differently under different circumstances. There are a number of properties of matter which can be explained in terms of molecular behaviour. Among these properties is elasticity. Intermolecular forces: these are electromagnetic forces between molecules. The strength and direction of these forces differ in accordance to the separation of the molecules. Materials are often subjected to different forces. Forces can be distorting, that is they can alter the shape of a body. Two distorting forces I shall look at are tension and compression. Tension/tensile stress, more generally referred to as stretch, happens when external forces (larger red arrows) act on a body so that different parts of that body are pulled to go in different directions. In most materials, the intermolecular force (smaller aqua arrows) of attraction shows resistance to these external forces, so that once the external forces have abated, the body resumes its original shape/length. Compression/compressive stress, more generally referred to as squashing, happens when external forces act on a body of material so that different parts of that body are pushed in towards the centre of the body. In most materials, the intermolecular force of repulsion acts against these external forces, so that when the distorting force is removed, the molecules return to their original arrangement and spacing. Materials that do this are known to have the property of elasticity. In short, elasticity is the ability of a material to return to its original shape and size after distorting forces (i.e. tension and/or compression) have been removed. Materials which have this ability are elastic; those which do not have this ability are considered plastic. This always happens when the distorting force is below a certain size (which is different for each material). This point where the body will no longer return to its original shape/size (due to the distorting force becoming too large) is known as the elastic limit (which differs from material to material). As long as the distorting force is below this size, the body that is under the external forces will always return to its original shape. As the body is put under more and more stress (distorting force), the body strains (deforms, extends) more and more. Right up to the elastic limit, the body will continue straining, in accordance to the size of the stress. This is where Hooke’s Law comes in. Hooke’s Law states that, when a distorting force is applied to an object, the strain is proportional to the stress. For example, if the load/stress is doubled, then the extension/strain would also double. However, there is a limit of proportionality (which is often also the elastic limit), only up to which Hooke’s Law is true. Since the strain is proportional to the stress for different materials where Hooke’s Law is true, then there should be a fixed ratio of stress to strain for a given elastic material. This ratio is known as its Young’s Modulus. Young’s Modulus can be calculated from the stress and the strain of an object under tensile/compressive stress. e = change in length/extension of object, in cm p = original length of object, in cm a = cross-sectional area of object, in cm2 f = size of force applied, in newtons For example, the Young’s Modulus of Mild Steel = 2 x 1011 N m-2 Copper = 11 x 1010 N m-2 Hooke’s Law and Young’s Modulus apply to most elastic materials, with the exceptions. A special shape which material can be bent into to in order to optimize use of the elasticity of a material is a spring. Springs are used by us everywhere: in seats, mattresses, cars, toys, and all other sorts of necessary objects and items we encounter in our daily lives. They are normally made from metal, though they can come from plastics, rubber or even glass. When compressive stress is applied to a spring, the spring noticeably ‘shortens’, though the actual length of the body material shortens very little. It is due to this special shape of springs that let it do this. The same occurs when tensile stress is applied. When a spring is being extended or pulled on, it may seem the spring is changing length dramatically, but in actual fact the spring’s body material relatively doesn’t change shape at all, but rather the shape of the body is more spaced out. AIM My objective in this experiment is to find out how a spring varies in length with added load. I also want to witness Hooke’s Law in action, and I want to observe the behaviour of the spring/s even after the load added causes the stress in the spring to exceed the elastic limit. PLAN My experiment is fairly straight forward to set up and carry out. In my experiment the data that I intend to assemble is the extension of the spring each time new/extra load is added to it. It is necessary that I use the most appropriate equipment for my experiment, hence I have chosen to use a retort stand which will hold up the spring and its weights up, a second retort stand from which a meter rule will be suspended. The metre rule will be right up against the spring, so as to ensure an accurate reading. There is no evidence that I can take before hand, other than the material of the spring. This entire experiment has to be as accurate, fair, precise and reliable as can practically be, but it is only possible to make it so to a certain extent. For instance, I cannot be absolutely sure that that all Newton weights weigh exactly 1000 grams, nor is it practical to find a ruler that is absolutely accurate. Hence I am forced to settle for the metre rule, which is accurate to about 1 millimetre, and I will be aware that the Newton weights will be within an accuracy of about i 20 grams. These factors will not really be in my control; however I can reasonably account for them when I construct a graph from my table by using error bars for each point plotted. Another measure I am taking is that I shall not be the only one to take readings from the metre rule; I shall have two other peers who will also be reading off the same metre rule. From these 3 readings I shall draw up averages of level of weight applied to the spring. To be practical and observing at the same time, I must choose an appropriate extent and range, as well as appropriate integers, for the data that I intend to collect. I will be going to take the first measurement as the length of the spring when there is no mass attached to it. The last measurement shall be right up to when the spring can no longer hold on to the weights. I have a rough idea of the spring that I shall use, and I am assuming now that the spring shouldn’t be able to hold much more than 13 kg. I shall be adding the weights one at a time (one Newton/kilogram at a time), and I shall be taking measurements at each of these intervals. The measurements that I shall take of the length of the spring will be in millimetres. So basically, once I have set up the entire apparatus, I shall start off taking the measurement of the spring when it is free of load, then let my peers take theirs. Then I shall add a Newton weight one at a time, taking measurements with my helpers each time I add one. Of course we’ll be wearing our goggles, because I don’t want to take any risks. 1) Collect equipment. 2) Prepare apparatus as shown in diagram. 3) Record the length of the spring when it is load-free, to cm, in the prepared table for results. 4) Add a weight/mass of 1 kg or 1 N, and then take the new length of the spring. Record in the prepared table for results. 5) Continue adding on weights/masses of 1 kg, recording the length of the spring each time in the prepared table for results. This should be carried on until the weights can no longer be attached to the hanging spring. APPARATUS. The apparatus that I shall need set up for my experiment consist of the following items: 1. Retort Stands (x 2) 2. Boss and Clamps (x 2) 3. Metre Rule 4. Spring (length: 50 mm) 5. Newton Weights (x 15 approximately) Other items I shall need are three pairs of goggles. SAFETY I must consider my safety when working in the laboratory. It is common when this type of experiment is carried out that when a weight or anything for that matter is suspended from something as unstable as a hanging spring, the item in being suspended is prone to fall.

Prior to the 1990’s, the problem of scientific objectivity was a question many philosophers tried to grapple with. Initially, the Logical Positivist’s view of scientific objectivity was most popular. They held to the belief that science was overall objective because of the distinction between the â€Å"context of discovery† and â€Å"context of justification,† which still allowed for science to contain some subjective elements (Longino 172). Basically, Positivist’s allowed for subjective qualities, such as mental makeup of scientists and values scientist brought in to their scientific work, by stating that the initial formulation or â€Å"discovery† of hypothesis/theories included subjective qualities. However, these subjective characteristics were†¦show more content†¦Longino believes that there are two types of objectivity in science. In one sense, Objectivity 1, she says that science describes the world as it is, gets it right, an d has no interpretation laid out on the data. In this sense, science is objective because there is no way subjective factors can even affect the scientific data. Longino states that this is the ideal sense in which science should be like, because it is completely objective and still gets everything correct. However, Longino states that this is not how science works in reality. On the other hand, she states that science is objective (Objectivity 2) because of the process in which science works. In one interpretation of this view, we can say that science is objective because it uses an objective process, commonly called the scientific method, and as a result the results are objective. According to Longino this is the naà ¯ve interpretation of objectivity and she describes a different interpretation of Objectivity 2. For Objectivity 2, the process of science in not necessarily objective, but instead the process leads to objectivity. So you may ask how can a process that is not objecti ve lead to an objective result? For Longino, the answer lies in values and other subjective factors.
