Essay about Physics of the Eyes - 1171 Words

Protections of the eye: The human eye is one of the most important things to a person and thus has many forms of protection. The eyelid protects the eye in three different ways: the eyelashes, the glands, and the movement of the eyelids. The eyelashes are beneficial in keeping dust and debris out of the eye. Touching the lashes will trigger the reflexive blinking mechanism. There are many different glands that are located in the eye. The Zeis gland is a gland that secretes oil. An infection in this gland results in a stye. A second gland, the Meibomian gland, are large oil secreting glands located in the lid of the eye and play a part in producing the oily outer layer of tears. This oily layer prevents the evaporation of tears.†¦show more content†¦* Descernets membrane This layer is simply secretory products from the endothedlium. * the endothedlium The innermost layer of the eye is a single layer of cells that are lined up against Descemets membrane. The quality and quantity of these cells decrease over time and cannot be replaced. When one cell dies, the rest of the cells enlarge to keep the same distance covered. The Iris and Pupil: The most commonly known parts of the eye are the iris and the pupil. The iris is made of connective tissue and muscle that contains a hole in the midst of them. The iris is the part of the eye that is colored, either brown, green, blue, hazel, etc. The color is a result of the amount of pigment that is found in the eye, brown eyes have a lot of pigment, and light eyes, such as blue, have little pigment. The pupil is the hole in the eye that allows light to reach the retina. The pupil widens in a darker room to allow more light in, and narrows when in the light to restrict the amount of light to reach the retina. The pupil is adjusted by the iris muscles. The Lens: The lens is located in front of the iris. It is an elastic body, it stretches and returns to its former place. It is biconvex, and almost transparent. Directly in front of the lens is the aqueous, and directly behind it, the vitreous. The lens is one of the items in a persons body that deteriates with age, like many other bodyShow MoreRelated Physics of the Human Eye Essay2076 Words   |  9 PagesPhysics of the human eye.

Racism in the Adventure of Huckleberry Finn Free Essays

Huckleberry Finn is a wonderful book that captures the heart of the reader in its brilliance and innocence. Despite many critics have attacked its racist perspective;the piece merely represents a reality that occurred during antebellum America,the setting of the novel. Twain’s literary devices in capturing the focal of excitement,adventure,and human sympathy is a wonderful novel that should be recognized,not for bigotry, but that it is the candid viewpoint of a boy that grew up in that era. We will write a custom essay sample on Racism in the Adventure of Huckleberry Finn or any similar topic only for you Order Now And even then,the protagonist does overcome some social prejudices of slavery because he is concerned with the well-being of his runaway slave friend Jim. That the mockery of the slave race in the end allowed by Huck is more about fulfilling the awes of Huck towards Tom. The novel is a success because it does not fail to capture the one singular point of growing up for Huck:boyhood. Mark Twain definitely characterizes the protagonist,the intelligent and sympathetic Huckleberry Finn,by the direct candid manner of writing as though through the actual voice of Huck. Every word,thought, and speech by Huck is so precise it reflects even the racism and black stereotypes typical of the era. And this has lead to many conflicting battles by various readers since the first print of the novel,though inspiring some. Says John H. Wallace,outraged by Twain’s constant use of the degrading and white supremacist word‘nigger’,†[The Adventures of Huckleberry Finn is]the most grotesque example of racist trash ever written†(Mark Twain Journal by Thadious Davis,Fall 1984 and Spring 1985). Yet,again to counter that is a quote by the great American writer Ernest Hemingway,†All modern American literature comes from one book by Mark Twain called Huckleberry Finn†¦it’s the best book we’ve had†¦There has been nothing as good since†(The Green Hills of Africa [Scribner’s. 1953]22). The controversy behind the novel has been and will always remain the crux of any readers is still truly racism. Twain surely does use the word‘nigger’often,both as a referral to the slave Jim and any African-American that Huck comes across and as the epitome of insult and inferiority. However,the reader must also not fail to recognize that this style of racism,this malicious treatment of African- Americans,this degrading attitude towards them is all stylized of the pre- Civil War tradition. Racism is only mentioned in the novel as an object of natural course and a precision to the actual views of the setting then. Huckleberry Finn still stands as a powerful portrayal of experience through the newfound eyes of an innocent boy. Huck only says and treats the African-American culture accordingly with the society that he was raised in. To say anything different would truly be out of place and setting of the era.Twain’s literary style in capturing the novel,Huck’s casual attitude and candid position,and Jim’s undoubted acceptance of the oppression by the names all signifies this. The thesis has three chapters. Chapter one is introduction of the whole work. Chapter two give some information about the criticism literature. Chapter three give a deep look at the research about the racial problems in the book Huck Finn. Chapter four is the conclusion part. 1 Literature Review Literary criticism is an attempt to evaluate and understand the creative writing,the literature of an author.Literature includes plays, essays,novels,poetry,and short stories. Literary criticism is a description,analysis,evaluation,or interpretation of a particular literary work or an author’s writings as a whole. Literary criticism is usually expressed in the form of a critical essay. In-depth book reviews are also sometimes viewed as literary criticism. Controversial in death as he was in life,Mark Twain has been seriously accused by some of being a†racist writer,†whose writing is offensive to black readers,perpetuates cheap slave-era stereotypes,and deserves no place on today’s bookshelves.To those of us who have drunk gratefully of Twain’s wisdom and humanity,such accusations are ludicrous. But for some people they clearly touch a raw nerve,and for that reason they deserve a serious answer. Let’s look at the book that is most commonly singled out for this criticism,the novel that Ernest Hemingway identified as the source of all American literature:The Adventures of Huckleberry Finn. For Twain’s critics,the novel is racist on the face of it,and for the most obvious reason:many characters use the word†nigger†throughout.But since the action of the book takes place in the south twenty years before the Civil War,it would be amazing if they didn’t use that word. A closer reading also reveals Twain’s serious satiric intent. In one scene,for instance,Aunt Sally hears of a steamboat explosion. â€Å"Good gracious! anybody hurt? â€Å"she asks. â€Å"No’m,†comes the answer. â€Å"Killed a nigger. † But anyone who imagines that Mark Twain meant this literally is 580 SCIENCE;TECHNOLOGY INFORMATION2010 5? missing the point.Rather,Twain is using this casual dialogue ironically, as a way to underscore the chilling truth about the old south,that it was a society where perfectly†nice†people didn’t consider the death of a black person worth their notice. To drive the point home,Twain has the lady continue: â€Å"Well,it’s lucky,because sometimes people do get hurt. † That’s a small case in point. But what is the book really about? It’s about nothing less than freedom and the quest for freedom. It’s about a slave who breaks the law and risks his life to win his freedom and be reunited with his family,and a white boy who becomes his friend and helps him escape.Because of his upbringing,the boy starts out believing that slavery is part of the natural order;but as the story unfolds he wrestles with his conscience,and when the crucial moment comes he decides he will be damned to the flames of hell rather than betray his black friend. And Jim,as Twain presents him,is hardly a caricature. Rather,he is the moral center of the book,a man of courage and nobility,who risks his freedom–risks his life–for the sake of his friend Huck. Note,too,that it is not just white critics who make this point. Booker T. Washington noted how Twain†succeeded in making his eaders feel a genuine respect for’Jim,'†and pointed out that Twain,in creating Jim’s character,had†exhibited his sympathy and interest in the masses of the negro people. † The great black novelist Ralph Ellison,too,noted how Twain allows Jim’s†dignity and human capacity†to emerge in the novel. â€Å"Huckleberry Finn knew,as did Mark Twain[Ellison wrote],that Jim was not only a slave but a human being[and]a symbol of humanity†¦ and in freeing Jim,Huck makes a bid to free himself of the conventionalized evil taken for civilization by the town†Ã¢â‚¬â€œin other words,of the abomination of slavery itself. In fact,you can search through all of Twain’s writings,not just the thirty-plus volumes of novels,stories,essays,and letters,but also his private correspondence,his posthumous autobiography and his intimate journals,and you’ll be hard put to find a derogatory remark about the black race–and this at a time when crude racial stereotypes were the basic coin of popular fiction,stage comedy,and popular songs. What you find in Twain is the opposite:a lively affection and admiration for black Americans that began when he was still a boy and grew steadily through the years.In a widely praised post-Civil War sketch titled†A True Story,†for example,he wrenchingly evoked the pain of an ex-slave as she recalls being separated from her young son on the auction block, and her joy at discovering him in a black regiment at war’s end. And on those occasions when Twain does venture to compare blacks and whites,the comparison is not conspicuously flattering to the whites. Things like: ?†One of my theories is that the hearts of men are about alike,all over the world,whatever their skin-complexions may be. † ?†Nearly all black and brown skins are beautiful,but a beautiful white skin is rare. ?†There are many humorous things in the world;among them is the white man’s notion that he is less savage than all the other savages. † 2 Methods/Research Design The null hypothesis for this research is that half of the university students study literature will think that there are racial discrimination in the book Huck Finn and others won’t. 1000 students in their third and forth years of university will be the subject. They must never see the book or the movie of Huck Finn. They come from both big cities and rural area. They are divided into four groups.The first two groups(each has 250 students)include the students from big cities,part of them students from rural areas. First,all of them will hear the story of Huck Finn. Then they wi answer relevant questions about the images of Huck Finn in th questionnaires and during the interviews. The questions are about th using method of language,the plot design and the thinking of Huck,et Finally,the movie of Huck Finn will be shown. Students will describe th image of Huck and their views about racial problems in this book According to their answers,different answers will be divided into differen groups.After these works,comes the analyses of the statistics and dat After comparing the answers of the four groups,gives the conclusio whether literary students from big cities and from rural areas have th same opinion of the racial discrimination in this book. As expected,half o them will have the same opinion and half of them won’t. 3 Anticipated Results 3. 1 Time-Table My studies will last more than two years. I decide to spend about 5 hours per month on my studies. I plan to spend the first six month developing my proposal and methodology and completing the literatur review.During this period,I will also attend some relevant courses abou reader’s response theory. Then I will spend about six months i questionnaires and interviews. After that,I plan to spend eight months i analyzing the statistics and data. Finally,four month will be used mainl on the thesis.
