Balloon Car Essay Example for Free

Balloon Car Essay Our first idea was to make a paper Lamborghini. We looked on many websites to find ways to make an origami-type Lamborghini. All of the instructional videos that we found were at least an hour-and-a-half, or did not even look like a car. As we got to school I had the idea to look up paper models of Lamborghinis, the kind where it has the dotted lines and you cut it out, fold it where it says to, and tape it together. We printed it out and we could not get it big enough on a standard-sized piece of printer paper. There were five basic shapes on the model so we just decided to take five pieces of paper and draw the shapes much bigger and duplicate the design. After we drew the design and cut it all out we decided to cut out pieces of cardboard the same shape and put it behind the paper so it was more stable and added some weight. For our balloon, we put a hole in the back of the car that we could put a straw through, and taped the balloon to the straw. We taped the straw up on the back part of the car so when we blew up the balloon it would go straight up. Our wheel idea came to mind when I was drawing out an idea for our car. I was using a blue highlighter, accidentally dropped it, and we discovered how fast it rolled. We decided to try to pop out the center part of the highlighter so we could put a piece of wire through the center through the two ends and hook the wire through the bottom part of the sides of the car. We were going to use two highlighters, one in the front and one in the back, instead of â€Å"4 wheels†. However, we could not get the center out of the highlighters. We went â€Å"dumpster diving† around the school and ending up getting pop caps from Ms. Chambers. Since our idea was to use highlighters and the wire, once we hammered a hold through each of the caps, we couldn’t figure out how to make them turn because we did not have a good axle. We tried to use just a straw for the axle and that did not work. We then tried to compact the straw so it was not as big around and that did not work either. We also tried to put nails through the caps and stick the nails into the side of the car but that did not work either. Our next idea was to go to the band room and put four timpani wheels on the bottom of our car, but they were way too heavy. Eventually we smashed the straws to make them thinner and put it inside a hollowed-out pen. This made a good axle and we used this for our car. As we tested our car to see if it would move, it did not. We realized that our car may be too heavy so we had to think of a Plan B. We decided to take five kabob sticks and hot glue them side-by-side so it was pretty much flat. We then put our Pepsi cap wheels on the bottom, and taped the straw and balloon on top. We tested it and it moved over five meters and the path it took was fairly straight. The speed of our car is 2. 37 Meters/second. We found our speed because it took 2. 37 seconds to travel one meter. Our car is a good example of inertia. It keeps moving until its â€Å"power source† (balloon) runs out of air. It stops it because if the balloon never ran out of air, and if there was nothing in its path, our car would never stop moving. It’s also an example of acceleration because it starts off slow, gets a little faster, and as the balloon starts to run out of air, it slows down again. It’s also an example of every action has an equal and opposite reaction, because as the balloon releases air the car moves.

A Clockwork Orange Essay: The Future Dystopia -- Clockwork Orange Essa

The Future Dystopia in A Clockwork Orange      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   A Clockwork Orange is an anti-utopian novel, describing an imminent future in a stately supervised country. The hero Alex revolts against the state using violence and is therefore locked up. Later he is turned into a harmless subject without free will, incapable of committing any crime.    Burgess paints a future outlook of a land that is still committed to democracy, yet has already adapted radical methods facing youth criminality. There are several indications leading to the supposition that the general form of the government is a socialist one, e.g. the teenage slang called Nadsat which handles chiefly Russian vocabulary, streets named after personalities like Yuri Gagarin and paintings of nude working men in the style of Russian socialist art. So the state is on the say to become totalitarian, after the example of many communist countries.    In addition Alex lives in a society which lacks individualism and opposition. Under the strict governmental rule ordinary citizens are deceived end benumbed by TV and drugs. Moreover books and newspapers are hardly read, theatres and cinemas rarely visited. Everything is done to prevent normal subjects from thinking.    The few people representing an opposition against the government are hooligans like Alex and political reactionaries like Mr. Alexander and his friends. Hooligans are relatively held under control by a strong police force, reactionaries don't have any support from the people. Indeed there is a regular opposition in the country, yet it seems to come into terms with the ruling party.    This leads us back to Burgess' opinion that we should not trust the state. The hero Alex is in fact ... ...tine Books, 1984, (1965), S. 171-177 Hahn, Ronald M. und Volker Jansen. Uhrwerk Orange, in: Hahn, Ronald M. und Volker Jansen.

A Comparative Analysis

The field of psychotherapy provides a therapist 11 diverse therapeutic systems, all of which are designed to achieve the same goal – to address the problems, whether emotional or mental, of the client. Some of these systems call for an active and directive participation from the therapist while some requires him to â€Å"hold back† and let the client heal himself. This paper aims to tackle the differences as well as discuss similarities between two of the eleven available counseling approaches – the Psychoanalytic Therapy and Person-Centered Therapy.Comparative Analysis 3 A Comparative Analysis of Two Counseling Approaches Two of the most-utilized counseling approaches are Psychoanalytic Therapy and Person-Centered Therapy. Perhaps due to its very opposite characteristics, these approaches embrace the two types of clients – one who wishes to sit down, talk, remain distant and maintain no personal relationship with the therapist and one who prefers to spill his thoughts while creating an intimate relationship with the therapist. DefinitionAccording to Psychology Today, Psychoanalytic therapy is a general name for therapeutic approaches which try to get the patient to bring to the surface their true feelings, so that they can experience them and understand them. In this kind of therapy, the unconscious is studied with a focus on dreams, behavior, slips of tongue, post-hypnotic suggestion, and the use of techniques that provide the client an opportunity to search their thoughts for links to various issues and problems. Unconscious thoughts and processes are the basis for all forms of problem symptoms and behaviors.On the other hand, a Person-Centered Therapy, sometimes called Rogerian Therapy, focuses on immediate conscious experience. Rogers (1977) describes this form of therapy as a process of freeing a person and removing obstacles so that normal growth and development can proceed and the client can become independent and self-direct ed. Unconscious vs. Conscious Psychoanalytic therapy holds that bringing the unconscious into conscious awareness promotes insight and resolves conflict. (Psychology Today) According to Freud, human beings are basically determined by psychic energy and by early experiences.Unconscious motives and Comparative Analysis 4 conflicts are central in present behavior. Making the client aware of his unconscious motives by interpreting his dreams and thoughts will lead him to freedom of mind and body. Person-Centered therapy, on one hand, deals with immediate conscious experience. Its primary purpose is to provide a deep understanding and acceptance of the attitudes consciously held at this moment by the client as he explores step by step into the dangerous areas which he has been denying to consciousness.(Personality & Consciousness) This form of humanistic therapy deals with the ways in which people perceive themselves consciously rather than having a therapist try to interpret unconscious thoughts or ideas. (Depression-Guide, 2005) Directive vs. Non-directive Psychoanalytic therapy is directive in nature such that the therapist allows the client to talk freely but in the process asks a number of questions, dictates length and frequency of sessions, and advises client on how to deal with things and how to view certain issues.Person-centered therapy is non-directive. It is an approach to counseling and psychotherapy that places much of the responsibility for the treatment process on the client, with the therapist taking a non-directive role. (Mind Disorders, 2007) The therapist's role is mainly to act as a facilitator and to provide a comfortable environment, rather than to drive and direct therapy outcomes. (Lots of Essays, 2009) The client is seen as the core therapist, with the actual therapist serving as consultant, advisor, witness, and support system.Then vs. Now Psychoanalysis places significant importance on early development. (Psychology Today) It believes th at such is of critical importance because later personality problems have their roots in repressed childhood conflicts. Comparative Analysis 5 In Rogerian therapy, attention is given to the present moment and on experiencing and expressing these feelings in order to move towards a more beneficial direction. TechniquesThe therapist employing Psychoanalytic Therapy uses techniques such as free association (the client reports anything that comes to mind), dream analysis, interpretation, analysis of resistance and transference, and understanding of counter-transference, to find commonalities in the client’s thoughts and behaviors and to interpret them in terms of the client’s problems. (4therapy Network, 1998) In a Person-Centered therapy, few techniques are utilized.Research has shown that the most significant variables in the effectiveness of this therapy are aspects of the relationship and the therapist's personal development – not the particular discipline they practice or techniques they employ. The therapist is expected to create an atmosphere that is both suitable and comfortable for the client in order for him to freely express his feelings and direct himself towards healing. In fact, in order for this type of therapy to be effective, it requires three things – unconditional positive regard, empathy, and genuineness or congruence.(Rogers, 1961) Unconditional Positive Regard. This unconditional positive regard, or something like love, can allow the client to expose his vulnerabilities, fears, flaws, secrets, and dysfunctions within the therapeutic setting without fear of being rejected. This allows the therapist to gain the necessary insights on the client's worldview and overall situation that enables the therapist to devise interventions, or make suggestions, that can help the client shift that worldview in a beneficial direction. (Lots of Essays, 2009) Comparative Analysis 6Empathy. Empathy refers to understanding the client's feelings and personal meanings as they are experienced. The therapist encourages the patient to express their feelings and does not suggest how the person might wish to change, but by listening and then mirroring back what the patient reveals to them, helps them to explore and understand their feelings for themselves Congruence. Congruence on the part of the therapist refers to his ability to be completely genuine and transparent. He does not present an aloof professional facade.(Mulhauser, 2002) There is no air of authority or hidden knowledge, and the client does not have to speculate about what he is really like. This is very far from what is being done during psychoanalytic therapy sessions wherein the client lies on a couch facing away from the therapist, minimizing opportunity for client-therapist relationship. Length of Session Two or more years with multiple sessions each week is required to fully apply and utilize Psychoanalytic Therapy. (Psychology Today) In contrast, the re are no strict guidelines regarding the length or frequency of sessions in a Person-Centered Therapy.Generally, therapists adhere to a one-hour session once per week. However, true to its spirit, scheduling may be adjusted according to the client's expressed needs. The client also decides when to terminate therapy. Termination usually occurs when he or she feels able to better cope with life's difficulties. (Mind Disorders, 2007) Applications Analytic therapy is not recommended for self-centered and impulsive individuals or for people with psychotic disorders, in the same way that person-centered therapy is not intended for a specific age group or subpopulation.While psychoanalysis essentially wrote off some groups, Comparative Analysis 7 like schizophrenics or borderline personality disorder types, person-centered psychotherapies assume that all people could be worked with and that the answer to their dysfunction lay within them. (Mind Disorders, 2007) Person-Centered Therapy has been used to treat a broad range of people and has also been applied to persons suffering from depression, anxiety, alcohol disorders, cognitive dysfunction, and personality disorders.Some therapists argue that person-centered therapy is not effective with non-verbal or poorly educated individuals; others maintain that it can be successfully adapted to any type of person. The person-centered approach can be used in individual, group, or family therapy. With young children, it is frequently employed as play therapy. Criticisms of the Two Approaches One major criticism of Psychoanalytic Therapy is its inability to cure one of the most common and major emotional disorder – depression.People, it is believed, need ‘insight', before they can change. This means that you have to understand why they are depressed before you can get better. On the face of it, this seems perfectly reasonable, particularly as it seems to match the natural human response to a problem – to fi nd out why. However, in depression, this style of thinking will tend to make the depression worse. The problems with this type of counseling for depression are many. First, the focus is predominantly on the past. Depressed people do this plenty already.One main idea is to discover ‘the reason why'. There is rarely any single ‘reason why' with depression, and even if there was, discovering it does not make the depression go away. Take this for example, if you know why you blush, does the blushing stop? Comparative Analysis 8 Some therapists have been sued for using this approach in the US when treating depression. Approaches which mainly focus on the past are not recommended in the treatment of depression and anxiety conditions. (Depression Guide, 2005)As for Person-Centered Therapy, there is no other aspect which comes under such vigorous attack aside from the implications of the therapist acting as a facilitator rather than as a counselor. It seems to be genuinely distu rbing to many professional people to entertain the thought that this client upon whom they have been exercising their professional skill actually knows more about his inner psychological self than they can possibly know, and that he possesses constructive strengths which make the constructive push by the therapist seem puny indeed by comparison.The willingness fully to accept this strength of the client, with all the re-orientation of therapeutic procedure which it implies, is one of the ways in which client-centered therapy differs most sharply from other therapeutic approaches. (Rogers, 1946) Personal Viewpoint I strongly believe that a Person-centered therapy works best for me, not because I have once seeked the help of a professional therapist, but because I feel that my father had served as my own therapist – employing the Person-centered therapy on me.There was one time when I felt so down about not being able to make it to the top of the class for a certain school year . You see, I’m an A-grade student – the cream of the crop. I even graduated with First Honors in grade school. Come high school, though, I belonged to a class where everyone is â€Å"the best† in their own schools. Competition was tough. Anyone who doesn’t live up to the expectation is transferred to another section to mingle with the average students. The â€Å"Number One’ student in me struggled to keep up. I did for the first three years. However,Comparative Analysis 9 come the last year in high school, I was suddenly faced with the fact that I didn’t make it. I no longer belong to the prime class. It was painful. It was unacceptable. The reason for not making it was simply because of a Technology Project – an amplifier that’s supposed to make a bulb light up. Unfortunately, mine didn’t when the professor inspected it. That was it – no considerations, no second chances, I got a low mark. I was informed a month before the next school year starts. That month was indeed a difficult time for me.I remember crying several nights talking to myself and still, I wasn’t feeling any better. I felt that my parents were disappointed of me; my friends were not sad enough that I’m leaving the class. What helped me to move on and accept the turn-out of events was my father – he sat down with me, just listening and helping me spill my guts. I talked non-stop, crying and just telling him that I hate myself for what has happened, that I cannot yet accept that I failed, that he has to do something about it. My father just sat there, letting me talk.He listened – making no negative comments, not judging me or blaming me or telling me that I’m wrong. He would always repeat the things I said in the form of questions. He was literally mirroring me. I guess that was his way of letting me know that he is really there, he is listening intently and not just pretending to. He did n ot even use the usual â€Å"parent line† â€Å"I’ve been there, Child. What you need to do is†¦Ã¢â‚¬  And thinking about it now, I am thankful that he didn’t. Had he said those words, I would have reacted negatively by saying â€Å"No, you don’t know how I’m feeling.You never had to go through something like this! † I would have regarded him as one of my peers who I felt that time didn’t care much as they are still part of the class. I would have stopped opening up to him. Comparative Analysis 10 My father’s technique, as I study the different approaches of therapy, is very much the same as that of the Person-centered Therapy. And luckily, it worked for me. I ended up hearing myself over and over again – talking about the same things, angry over the same stuff. Eventually, reason, understanding and acceptance came.My father must have known I wasn’t the type to take orders from people. He trusted that I am c apable of solving my own problems and facing my own dilemmas. The Challenge The key challenge in the field of psychotherapy is to find ways to integrate and combine certain features of various approaches in order to work with the needs of different clients. What is crucial is a strong knowledge of what a certain approach is – its advantages, strengths and weaknesses, applications and even recent studies/cases that may prove to be helpful in solving a client’s case.Comparative Analysis 11 References Cain, David J.

Romeo and Juliet Compare and Contrast

Compare and Contrast â€Å"Romeo and Juliet† is a story about two star crossed lovers who meet by fate. This great piece of literature written, by William Shakespeare will be compared with Baz Lurman’s rendition of â€Å"Romeo and Juliet†. The movie missed some details from the play it also added some extra scenes but it still contained the right mood and scenes for it to be a â€Å"Romeo and Juliet† movie. A major similarity between the movie and play occurs in mood.An example of this is the marriage scene. In the marriage scene of the play, Romeo and Juliet act very serious. The reader can tell this by the way the two speak. Romeo says that the Holy Words the Friar speaks can make something without an equal which is a very intelligent thing to say. Similarly in the movie Romeo and Juliet both act serious. This is shown through there clothes, faces, and by the way they act. Romeo wears a suit, and Juliet wears a beautiful dress.Also you can tell by there faces that they look determined to get married and they both act very professional their not jumping around like 5 years olds their acting how people should be when they are getting married. A humongous difference between the play and movie is that Romeo is being chased by the police as he is making his way to Juliet’s resting place. In the play this never even happened he just got on a horse and went to the place. Lurman had to include put a chase in there, but that’s just one weird thing in this scene the other one is that Romeo takes a hostage because he gets surrounded by the police.This part was probably not expected by a lot people. Another deference is the ending of both the play and movie. In the play thinking that Juliet is dead, Romeo drinks some poison. When Juliet wakes up and discovering Romeo died she stabs herself with his dagger. They both lie next to each other, dead, and Juliet has yet another funeral, and Romeo has one too. Their families bury their differences and end their long feud. They also built a gold statue to honour Rome and Juliet.In contrast the movie ends with Romeo finding Juliet dead so he drinks the poison but this time Juliet wakes up: but Romeo has already drunken the poison so Juliet shoots her self in the head. Some people were not too happy about that. In conclusion the movie contained the necessary elements for it to be a fairly good adaptation of William Shakespeare’s play â€Å"Romeo and Juliet† but it missed details from the play and added a few details which may not be liked by all audiences. Both the play and movie are great.

Three Top Financial Scandals in the Recent Past

Three Top Financial Scandals in the Recent Past Summary Financial scandals have been common in corporations for a considerable length of time. In this particular paper, fraudulent financial activities that have affected three companies have been discussed. The rigging of financial markets and large well established corporations is not a new phenomenon. However, the trend seems to be getting out of control in the modern economy.Advertising We will write a custom term paper sample on Three Top Financial Scandals in the Recent Past specifically for you for only $16.05 $11/page Learn More There are growing allegations that systematic robbing of financial institutions has been taking place in the past 3 decades or so. One of the worst impacts of financial fraud in these institutions is that the global interest ad exchange rates have always been forcibly fixed by a few fraudulent individuals. In other words, the market forces of demand and supply are hardly left to play their roles in the contemporary liberaliz ed economies. This paper offers a succinct discussion of three top financial scandals that have been witnessed in the recent past. Introduction When banks in London are engaged in the process of borrowing from each other, there is a specific charge that is levied on the service. This average interest rate is referred to as Libor. The Thomson Reuters usually play the role of calculating this value (Snyder, 2012). There are several instances when Libor matters a lot especially when it comes to the net value of a product or when borrowing loans from banks and other financial institutions. For instances, it is highly likely that Libor affects credit card usage and property loans in several ways. Even the US economy is significantly affected by Libor. Other scandals discussed in this paper include the Enron and WorldCom scandals. The London Interbank Offered Rate (Libor) To begin with, it is perhaps necessary to explore the culprits behind the Libor scandal. The fixing scandal for intere st rates is believed to have involved close to twenty major banks both in Europe and the United States. It has also been found out that banks spread across three continents were embroiled in the scandal. The scandal remarkably jeopardized the career of Bob Diamond who was serving as the chief executive officer at that time. Pressure mounted each day for the CEO to surrender his office while other several top professionals in the banking sector across the world were being compelled to quit their offices so that investigations could be started (Snyder, 2012).Advertising Looking for term paper on business economics?

This was a critical way of manipulatin g interest rates so that the overall financial performance of the bank could improve. Besides, this move boosted the profitability of the Barclays Bank (Snyder, 2012). This was a serious fraud bearing in mind that Libor is a leading interest rates benchmark across the global financial markets. The integrity of the interest rates was adversely affected by the Barclays’ behavior since it generally posed a gross financial threat to other market players. Enron Scandal The Enron scandal has also been noted as one of the most popular financial frauds that took place in the last decade. At the onset of the new century, Enron was a company to reckon with in several ways due to its performance and market stability (Foster, 2010). It recorded a tremendous success that several other companies could hardly attain. Nonetheless, a harbinger of elaborate challenges was recognized by investors when earnings restatement was announced by Enron in mid 2001. Within a period of merely one and a h alf months, Enron was declared bankrupt and unable to run its financial obligations in spite of the fact that it was powerful market performer and oozed with adequate wealth. The fraudulent financial activities that took place at Enron could be grouped into two categories. First, basic fabrication of numbers took place in the financial records of the company (Salter, 2008). For instance, when its venture with Blockbuster did not succeed, it was poorly valuated. Second, complex financial maneuvers were also witnessed prior to the fall of the company. Nonetheless, the American economic system is largely believed to have significantly contributed to the decline of Enron (Foster, 2010). The people’s trust in the performance of the entire economy was also weakened after the scandal. The executives of the company were described as greedy individuals who could not maintain their integrity as outlined in the code of ethics (Fox, 2003). WorldCom scandal Both the accounting fraud and e rosion of profits affected the performance and market stability of WorldCom company. Illusionary earnings amounting to billons were created in the eyes of investors whereas the company was headed to serious state of bankruptcy.Advertising We will write a custom term paper sample on Three Top Financial Scandals in the Recent Past specifically for you for only $16.05 $11/page Learn More One of the major impacts of this fraud was felt in the telecommunications sector. Millions of users were negatively affected by the declined performance of WorldCom Company (Romero, 2002). According to the financial records of this company, the net value of assets owned by the firm was estimated at $107 billion. Before this filing could be released to shareholders, the company reported that expenses amounting to about $3.8 billion had been improperly accounted for in the records. Telephone companies, suppliers, and banks were adversely affected by the fraudulent activities at the firm after the scandal was exposed. Before its bankruptcy, the total debts accumulated by the company stood at $41 billion. This marked the beginning of its downfall (Romero, 2002). Conclusion In recap, it can be seen that the financial scandals discussed caused major economic hitch in all the three companies. However, the common attributing factor was poor management of the firms’ resources. References Foster (2010). The decades worst financial scandals. Web. Fox, L. (2003). Enron: The Rise and Fall.

Argon Facts (Atomic Number 18 or Ar)

Argon Facts (Atomic Number 18 or Ar) Argon is a noble gas with element symbol Ar and atomic number 18. It is best known for its use as an inert gas and for making plasma globes. Fast Facts: Argon Element Name: ArgonElement Symbol: ArAtomic Number: 18Atomic Weight: 39.948Appearance: Colorless inert gasGroup: Group 18 (Noble Gas)Period: Period 3Discovery: Lord Rayleigh and William Ramsay (1894) Discovery Argon was discovered by Sir William Ramsay and Lord Rayleigh in 1894 (Scotland). Prior to the discovery, Henry Cavendish (1785) suspected some unreactive gas occurred in air. Ramsay and Rayleigh isolated argon by removing the nitrogen, oxygen, water, and carbon dioxide. They found the remaining gas was 0.5% lighter than nitrogen. The emission spectrum of the gas did not match that of any known element. Electron Configuration [Ne] 3s2 3p6 Word Origin The word argon comes from the Greek word argos, which means inactive or lazy. This refers to the extremely low chemical reactivity of argon. Isotopes There are 22 known isotopes of argon ranging from Ar-31 to Ar-51 and Ar-53. Natural argon is a mixture of three stable isotopes: Ar-36 (0.34%), Ar-38 (0.06%), Ar-40 (99.6%). Ar-39 (half-life 269 yrs) is to determine the age of ice cores, ground water and igneous rocks. Appearance Under ordinary conditions, argon is a colorless, odorless, and flavorless gas. The liquid and solid forms are transparent, resembling water or nitrogen. In an electric field, ionized argon produces a characteristic lilac to violet glow. Properties Argon has a freezing point of -189.2Â °C, boiling point of -185.7Â °C, and density of 1.7837 g/l. Argon is considered to be a noble or inert gas and does not form true chemical compounds, although it does form a hydrate with a dissociation pressure of 105 atm at 0Â °C. Ion molecules of argon have been observed, including (ArKr), (ArXe), and (NeAr). Argon forms a clathrate with b hydroquinone, which is stable yet without true chemical bonds. Argon is two and a half times more soluble in water than nitrogen, with approximately the same solubility as oxygen. Argons emission spectrum includes a characteristic set of red lines. Uses Argon is used in electric lights and in fluorescent tubes, photo tubes, glow tubes, and in lasers. Argon is used as an inert gas for welding and cutting, blanketing reactive elements, and as a protective (nonreactive) atmosphere for growing crystals of silicon and germanium. Sources Argon gas is prepared by fractionating liquid air. The Earths atmosphere contains 0.94% argon. Mars atmosphere contains 1.6% Argon-40 and 5 ppm Argon-36. Toxicity Because it is inert, argon is considered to be non-toxic. It is a normal component of air that we breathe every day. Argon is used in blue argon laser to repair eye defects and kill tumors. Argon gas may replace nitrogen in underwater breathing mixtures (Argox) to help reduce the incidence of decompression sickness. Although argon is non-toxic, it is considerably more dense than air. In an enclosed space, it may present an asphyxiation risk, particularly near ground level.

Bury My Heart at Wounded Knee - Movie Review Example It encompasses just a piece of the history that the book arrays over. This includes the battle of little Big Horn to the killing of sitting bull. This film directed by Yves Simoneau; however covers a lot more enough deceitfulness and deviousness and unfulfilled treaties on the side of the United Sates government. Yet still, the downside to it is are the approaches of the white men in charge, such like President Ulyness Grant. Grant is a good friend to the red Indians, who thinks that by contributing to the evolution of the red Indians best guarantees his survival. He also believes that there no way Sioux is going to be saved unless the rd Indians are obliged to give up their uncivilized way of life and patch up on the corollary. The whole anthropological, political and sociological careers have been exhausted by the disentanglement racism involved in statements such like those. Ironically, the burning of villages was clearly not an American discovery of 20th century. However, Bury My Heart at Wounded Knee is intoned with not only with scenes of this time but also of the late 18th century of the inevitably slow holocaust of the Native Americans.

This film was adopted form the novel Bury ‘My Heart at Wounded Knee† by Dee Brown. The movie links the ending years of a shameful chapter of American history. Straddling the period of 1850 to 1890, this film chronicles the destiny of the many native tribes who were forfeited for the sake of the white American gluttony for land tracks of land and readily available resources. From the onset, the film depicts the expunging of the Navajos from their ancestral homes to a proviso. On the same length, they are however permitt ed to return to their native land, which is somewhat less fertile. This film evokes the feeling that this event hallmarked the last fight of the Native American. Throughout the film, furthermore, voices of the past can still teasingly be heard. This film brings to mind the feeling that it was somewhat it is a lot more kind of a condemnation of white America and an outlook that perseveres until today. The hostile attitudes that permitted the United States government and Army to defeat a whole nation can be found in the American
