Relating to EE Cummings Poetry :: Biography Biographies Essays

Relating to EE Cummings' Poetry It's not necessarily easy to read. And it's probably harder to understand. But the poetry of ee cummings has made a nitch in our society of innovative minds and experimental art that we cannot argue. Whether we like it, hate it, or throw it down in frustration, we have to appreciate the door this poet has opened for so many generations of writers and stylists. We picked "my sweet old etcetera" because if was the simplist poems to understand, and there's a lot we could say about it (and we each had a 750 word responce paper ahead of us to think about.) "my sweet old etcetera" begins by describing the folks back home and their conversations of know-it-all nothingness. He describes how they share their righteous opinions about a war they know very little about. He uses the word "etcetera" throughout the poem as some people today use the phrase "blah blah blah" to trail the ends of their sentences. Come on, you know you say it. I know I do all the time..."my story is going to be about chasing dreams, and hopefulness, da da da da da." This poem discribes how hypocritical we all are. How we can talk about something that's happening a million miles away as if we know all, when we really can't possibly know anything about it. After reading it over and over again, I find that I can relate to this poem in one way. Last year, I had my first taste of being away from home. Back home, everyone was so proud of what I had accomplished--going so far away to follow my dreams. They knew without a doubt that I was going to be successful. They knew without a doubt that I was happy, that I was driven. They said so all the time. But what they didn't talk about were my everyday mistakes and misfortunes. They didn't mention that I no longer took center stage--that I rarely ever performed in town. they seems to pass over that awful semester of sociology and my first heartbreaks away from home. They didn't talk about it because in the long run, they knew all of that didn't matter.

Division Zombie Essay

Matt Coon Mrs. Scott English Comp 15 March 2013 Zombies A zombie is defined as a deceased human body that has somehow become reanimated and autonomous, yet no longer has sufficient brain or vital functions to be considered alive or capable of thought. The characteristics of a zombie have evolved over the years and throughout various cultures. In Africa they portray a zombie as a soulless being used as a slave for a voodoo priest. Never the less we will take a look at the American portrayal of the modern day zombie.We will do this by dividing the â€Å"zombie† into four different categories; the walkers, the runners, the crawlers, and the mutated zombies. In the older legends, zombie lore usually involved some form of voodoo or evil magic, but most modern zombie-themed media centralizes the idea of a rapidly spreading disease or virus causing the human species to turn into mindless beings with an intense hunger for the human flesh. Walkers were the first breed of zombie that ac tually craved human flesh. The usually spell-induced African zombies were just soulless beings; they had no desire to feast on people.Very fragile, and mostly decomposed, these â€Å"walkers† move extremely slowly. However, what they lack in agility, they make up for in magnitude. Usually walking around aimlessly, the walkers normally travel in groups, a lot like a flock of birds, but at the first sight of flesh the group converges and the next thing you know your overcome. Of all the types of zombies, walkers are probably the most realistic. The idea of somebody dying and being resurrected as a necrotic, dead cannibal is terrifying to a majority of the population.They may lurch about and stumble comically, but it only takes one to alert the rest of the group and nest thing you know you have an army chasing you from all directions. All for the BRAINS! Created to put zombie movies at a faster pace, the â€Å"runner† is not technically a zombie. Customarily originated by a man-made disease or virus, these zombies are exceedingly fast and viciously savage. This is why happening upon a single runner can be just as deadly as meeting an entire horde of the inferior walkers. Assumedly because quick, hard-to-catch targets darting around the screen present more of a threat han those slower moving zombies, runners often play the most crucial part in zombie-based video games and films of this day and age. Zombies are nothing but soul-less, rotting bodies; so what happens to them when they lose a part of themselves? Started by the popular video game Call of Duty, crawlers are normal zombies, walkers or runners, who had their legs dismembered in an attempt to kill them. Usually caused by trying to cut them or some sort of explosion. These zombies are typically slow moving and easy prey; but if you are not vigilant they can be very hazardous.Even if they can’t chase you down and attack you, they still carry whatever infection or virus put them in their current condition, and they are more than capable of passing it on while fighting you off. They will often attack the feet and ankles first, in attempts to infect and weaken you. Then, when you fall to the ground, they feast. Last of all, there are the mutated zombies. Mutated zombies were started by the popular video-game-turned-movie series, Resident Evil. Infected, panicked, and fighting to retain life, scientists attempted to create a serum to battle the virus.At first it seemed as if it was working, and the disease was to be cured; alas, most of them turned into to heaps of rotting, radioactive flesh, starving for the taste of brains. There are other cases where a zombie is doused in radioactive material, afterwards becoming virtually unrecognizable afterwards. These unlucky few are freakishly disfigured; they are also generally very agile and extremely strong. Not only infected, most mutated zombies also come radioactive, one touch who knows what may happen?Uninfected humans o ften have no chance of survival when standing up to one of these monsters. Even though the zombie apocalypse will probably never happen, it is always going to be one of the human race’s biggest fears. Maybe this essay will help somebody through it by knowing all of the many types of zombies, each one stronger and faster than the other. We also know never to turn your back on a zombie, even if it is just crawling around snapping at your ankles. The zombie apocalypse might not happen any time soon but it is always good to be prepared.

The Significance of the Townspeople and Emilys Father in...

A necrophiliac is described as a person who has an obsessive fascination with death and corpses (Mifflin 1). Emily, a necrophiliac in the story, â€Å"A Rose for Emily,† is a deranged, lost, and confused woman. A story filled with many symbols that help the stories meaning. The only man Emily knew growing up was her father. He taught her to trust no man, and no man would ever be good for her. He was highly favored through the town and everyone looked to him. The small town of curious and nosey people makes the story of â€Å"A Rose for Emily.† The town’s people are curious to know Emily’s every step, or wondering what she is going to do next, her appearance, and where the horrible smell in her house comes from.

Nothing is understood until the sickening truth is found out about her. It is all just one big mystery to them until her bedroom is unlocked. Faulkner also talks about the stench of Emily’s home. Our attention is drawn to her home when it is used to symbolize Emily and how she is growing old over the years. Emily’s home also has a great deal to do with the story because the home seems to be the townspeople’s vocal point. Everyone wants know where the horrific smell is coming from and what is in the closed out room that not a soul has gone into.

Definition of Air Pollution - 7529 Words

1. Definition of air pollution Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earths ecosystems. Indoor air pollution and urban air quality are listed as two of the worlds worst pollution problems in the 2008 Blacksmith Institute Worlds Worst Polluted Places report.[1] Define Air pollutants Pollutants Main†¦show more content†¦Within the NMVOCs, the aromatic compounds benzene, toluene and xylene are suspected carcinogens and may lead to leukemia through prolonged exposure. 1,3-butadiene is another dangerous compound which is often associated with industrial uses. * Particulate matter - Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. In contrast, aerosol refers to particles and the gas together. Sources of particulate matter can be man made or natural. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols. Averaged over the globe, anthropogenic aerosols—those made by human activities—currently account for about 10 percent of t he total amount of aerosols in our atmosphere. Increased levels of fine particles in the air are linked to health hazards such as heart disease,[3] altered lung function and lung cancer. * Persistent free radicals connected to airborne fine particles could cause cardiopulmonary disease.[4][5] * Toxic metals, such as lead, cadmium and copper. * Chlorofluorocarbons (CFCs) - harmful to the ozone layer emitted from products currently banned from use. * Ammonia (NH3) - emitted from agricultural processes.

Chemical Earth Notes free essay sample

The living and non-living components of the Earth contain mixtures. Identify the difference between elements, compounds and mixtures in terms of particle theory. An mixture is an impure substance that is, a pure substance contaminated with small amounts of one or more other substances. An element is a pure substance which cannot be separated into other simpler substances. A compound is a pure substance which can be decomposed into simpler substances e. g. elements. Identify that the biosphere, lithosphere, hydrosphere and atmosphere contain examples of mixtures of elements and compounds. The biosphere consists of atmosphere, lithosphere and hydrosphere. The atmosphere contains mixture of gases, and mainly the mixture of nitrogen, oxygen and argon and contains small amounts of gaseous compounds e. g. water, carbon dioxide, nitrogen dioxide, sulphur dioxide and carbon monoxide. The lithosphere contains an extremely diverse variety of mixtures: rocks: compounds of silicon, oxygen, and many metals sand: mainly silicon dioxide and fine dirt soils: clays, aluminium, silicon, oxygen, metals and decomposing animal and vegetable matter mineral ores: oxides, sulphides, carbonates, sulfates, chlorides coal, oil and natural gas: mixtures of compounds or carbon formed from decayed plant and animal matter Elements: iron, gold, silver, copper The hydrosphere major component is the compound water with small quantities of elements such as oxygen and nitroge n and compounds such as carbon dioxide, sodium, calcium and magnesium chloride and sulphates. We will write a custom essay sample on Chemical Earth Notes or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Apart from dissolved oxygen and nitrogen the mixtures of the hydrosphere contain only compounds. Identify and describe procedures that can be used to separate naturally occurring mixtures of: solids of different sizes, solids and liquids, dissolved solids in liquids, liquids and gases. Separation of solids of different sizes: Solids of different sizes can be separated by sieving Separation of solids and liquids: Solids and liquids can be separated by filtration e. g. sand from sea-water. Sedimentation is also a process of separation, decantation (pouring the liquid off and leaving the solid at the bottom undisturbed) can be done after this. Separation of issolved solids in liquid: evaporation is a method used so that the solid is left while the liquid is evaporated. Separation of liquids: distillation can be used, it is the process in which a solution or mixture of liquids is boiled with vapour formed by being condensed back to a liquid in a different part of the apparatus, and thus separating. Fractional distillation can also be used if the boiling points of two liquids are clo se together. Separation of gases: Gases are generally separated by using either differences in boiling points or differences in solubilities in liquids such as water. Identify the industrial separation processes used on a mixture obtained from the biosphere, lithosphere, hydrosphere or atmosphere and use the evidence available to: identify the properties of the mixture used in its separation identify the products of separation and their uses discuss issues associated with wastes from the processes used Separation of solids of different sizes: Solids of different sizes can be separated by sieving, separation of solids and liquids through sedimentation or decantation. Separation of dissolved solids in liquid by evaporating, separation of liquids with distillation or fractional distillation, separation of gases by using either differences in boiling points or differences in solubilities in liquids such as water. When separating salt water, that is sodium chloride (NaCl) and water (H2O), this will result in normal drinking water and table salt. 2. Although most elements are found in combinations on Earth, some elements are found uncombined Explain the relationship between the reactivity of an element and the likelihood of its existing as an uncombined element. The lower the elements reactivity the lower it is prone to react to another element, and this is because it only needs a minimum amount of electrons to become stable, meaning that it is already quite stable but not perfectly leading it not being that reactive and therefore staying as an uncombined element. Account for the uses of metals and nonmetals in terms of their physical properties. The common uses for metals such as iron, aluminium, copper and lead are for building materials, cars, planes, trains, machinery, electrical wiring, domestic appliances and household goods. It is the physical properties of the metals that most often determine which metal will be used for a particular product. The physical properties most commonly involved are melting point, density, electrical conductivity, hardness and tensile strength. The major uses of non-metals are as compounds. Wide ranges of compounds of non-metals are used in fuels, fertilisers, building materials, furniture, plastics, synthetic fibres, drugs, pesticides, paints, detergents, adhesives and cosmetics. Analyse information from secondary sources to distinguish the physical properties of metals and non-metals. Physical properties for Metals: Good electrical conductors and heat conductors. * Malleable can be beaten into thin sheets. * Ductile can be stretched into wire. * Possess metallic lustre * Opaque as thin sheet. * Solid at room temperature (except Hg). Physical Properties for Non-metals: * Poor conductors of heat and electricity. * Brittle if a solid. * Not ductile. * Do not possess metallic lustre * Transparent as a thin sheet. * Solids, liquids or gases at room temperature. Periodic Table: Semi-metals Semi-metals Non-metals Non-metals Naturally the substances that are liquids at room temperature (25 degrees) are mercury and bromine. The substances that are naturally gases at room temperature are oxygen, nitrogen, hydrogen, helium, neon, argon, krypton, xenon, radon, fluorine and chlorine. The rest are solids. 3. Elements in Earth materials are present mostly as compounds because of interactions at the atomic level. Identify that matter is made of particles that are continuously moving and interacting. All matter is made up of small particles. In solids, these particles are packed closely together in an orderly array. These cause solids to have definite shapes and to be relatively hard. In solids the particles vibrate slightly. In liquids, the particles are arranged in a much less orderly fashion than in solids and they move about much more freely. Particles in liquids possess more motion—more kinetic energy, we say—and the forces between neighbouring particles are comparatively weaker than in solids. The motion of particles in liquids is not confined to vibration as in solids, but also involves random translation from one place to another in the bulk of the liquid as shown. In gases, the particles are much further apart than in solids or liquids, and they are in very rapid random motion. The particles are so far apart and moving so rapidly that there are no significant forces between them. Describe qualitatively the energy levels of electrons in atoms. Electrons in an atom exist in discrete energy levels which we call first, second, third and so on. Each of these energy levels can only accommodate certain amount of electrons. The first level only holds 2 electrons and second hold eight, the nth energy level is calculated by the formula 2n2 electrons. Describe atoms in terms of mass number and atomic number. Atoms are made up of electrons, neutrons and protons. The protons and neutrons stay in nucleus and the electrons orbit around them. The atomic number is described by the number of protons in the nucleus. The atomic mass number is the number of protons + neutrons in the nucleus of the atom. Describe the formation of ionic compounds in terms of the attraction of ions of opposite charge. Ionic compounds are formed because an atom that is not stable tends to give away a certain amount of electrons to become stable while the other electron needs to gain some to become stable. These two atoms give and accept, leading them to become an ion. Therefore there are strong electrostatic forces holding the ions together as ionic compounds. Describe molecules as particles which can move independently of each other. Particles are packed closely together in an orderly array in solids. In liquids they are arranged in a much less orderly fashion than in solids, and they move more freely, and in gases the particles are much further apart than in solids or liquids and are in a very rapid motion gaining more kinetic energy leading to the particles moving independently. As the particles move faster and further in distance the significant forces between them diminish. Distinguish between molecules containing one atom (the noble gases) and molecules with more than one atom. All elements wish to have a noble gas configuration that is to become stable. Elements in group 1 lose 1 electron to become a stable. Group tend to lose 2 electrons, Group 4 elements either lose 4 or gain 4 electrons. Describe the formation of covalent molecules in terms of sharing of electrons. Covalent bonds are formed between pairs of atoms that both need to form noble gas configuration. This is done by creating a covalent bond, and sharing the needed amount of electrons, satisfying and stabilising both atoms. . Energy is required to extract elements from their naturally occurring source Identify the differences between physical and chemical change in terms of rearrangement of particles. Changing the state of a substance, changing the physical appearance, dissolving the solid in a liquid and separating mixtures do not require any new substance to be formed. A change in which no new substances are formed is called a physical change. On the other hand, when change in which at least a new substance is formed, e. g. heating green copper carbonate to form a black solid and colourless gas, is a chemical change. Summarise the differences between the boiling and electrolysis of water as an example of the difference between physical and chemical change. The processes boiling water and electrolysing water are two very different things. Eletrocysing the water causes it to produce two new substances, hydrogen and oxygen gases whereas the boiling of water just converts it from liquid to vapour. The electrolysis of water is also very difficult to reverse and hence the difference between physical and chemical change is portrayed through these two processes. Analyse and present information to model the boiling of water and the electrolysis of water tracing the movements of and changes in arrangements of molecule. When boiling the water just changes its’ state from liquid to vapour, and the amount of vapour is equal to the amount of water, therefore there are no new substances made and there isn’t any rearrangement of particles. However, in electrolysis the particles are rearranged into hydrogen and oxygen gases, hence creating a chemical change. Explain that the amount of energy needed to separate atoms in a compound is an indication of the strength of the attraction, or bond, between them. The amount of energy that is required is directly proportionate to the strength of the attraction or bond, the energy it takes to separate atoms in a compound indicates the strength of the bond. The stronger the bond is the more energy it will take to separate. 5. The properties of elements and compounds are determined by their bonding and structure Identify differences between physical and chemical properties of elements, compounds and mixtures. Elements cannot be separated into simpler substance, and the physical properties of metals and non-metals are different. Compound is homogenous and is a pure substance that can be decomposed into simpler substances that is, elements. Compounds are at least two different atoms bonded together, therefore when separated the chemical properties are different. Mixture is an impure substance that is contaminated with small amounts of one or more other substances, physical separation techniques can separate the impurities from the purities. Distinguish between metallic, ionic and covalent bonds. Covalent bonds are between non-metals and consists of 2 or more atoms sharing electrons. A metallic bonding is between metals and aims to sustain a noble gas configuration. Ionic bonds are between both non-metals and metals where one atom gives or receives electrons from each other to become stable. Identify common elements that exist as molecules or as covalent lattices. Phosphorus and sulfur exist as covalent P4 and S8 molecules respectively. H2, F2, Cl2, O2 and N2 are diatomic gases and Br2 is a diatomic liquid while I2 is a diatomic. Describe metals as three dimensional lattices of ions in a sea of electrons. Metals are three dimensional lattices of cations in a sea of delocalised electrons and it is the attraction between the positive and negative metal ions. Describe the physical properties used to classify compounds as ionic, covalent molecular or covalent network. The physical properties to classify compounds as: Ionic are: High melting point No solid conductivity No liquid conductivity Flexible and brittle Covalent Molecular: No conductivity Soft and brittle Low melting points Covalent network has: High melting points No conductivity Hard and brittle Describe ionic compounds in terms of repeating three-dimensional lattices of ions. Ionic compounds are in the form of repeating three-dimensional lattices of ions, formed by the transferral of electrons. The positively and negatively charged ions are joined by electrostatic attraction. Choose resources and process information from secondary sources to construct and discuss the limitations of models of ionic lattices, covalent molecules and covalent and metallic lattices. The main limitations of models of ionic lattices is that sometimes the indicative features only applies a minor amount of elements or does not include all the necessary features and is predicted. The model does not apply to all ionic compounds, it only explains a small amount of ionic compounds. These limitations are similar to covalent molecules and metallic lattices.

The Existence Of Hope Joy Luck Club English Literature Essay free essay sample

What will the universe semen to when everyone gives up on hope? The universe is full of unhappiness, but what motivates us to travel forward is hope. Hope is a major subject that comes to play in today s society. Peoples frequently run into quotation marks about life, such as unrecorded today as if there is no tomorrow or dream as if you ll populate everlastingly, live as if you ll decease today and there are many more ; however to state, they all come from the thought of hope. Without hope, homo would nt endeavor to be better and to make better, for hope inspires them to make their best and be their best to make his or her end. This subject is besides portrayed in the characters from the fresh Joy Luck Club written by Amy Tan. The female parents and girls in this book face many painful obstructions that cause them to lose their artlessness ; some gave up hope, while the others were able to derive cognition from their experience and usage hope as a manner to populate a more posit ive life. We will write a custom essay sample on The Existence Of Hope Joy Luck Club English Literature Essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page All in all, hope does non vouch absolute achievements ; alternatively it acts as a conduit to happen the interior strength within oneself. Oscar Romero one time said, Hope is non surrender ; it is a committedness to go on to fight. ; which explains An-mei female parent s decease. Because the constructs of hope means that one are able to happen the interior strength to go on to populate in an unpleasant or despairing state of affairs ; giving up hope means giving into 1 s ain fate/failure. An-mei s female parent clearly did non establish her life on the constructs of hope. Al though An-Mei s female parent lived a tragic life, she neer made the effort to take control over her life. Like Romero s quotation mark, An-mei s female parent did non compel to go on with the struggle to mend from it. Alternatively, she focuses on the negative things that happened in her yesteryear, such as being raped by Wu-Tsing and made her his courtesan, being bullied by the 2nd married woman and populating a disadvantage life ( non holding the portion of the house on the seashore or any regard in the household ) . All these things contribut ed to her loss of artlessness, but instead doing good usage out of the lessons she had experienced, she chose to acquire back at Wu-Tsing for her suffering life by devouring opium to stop her life [ .. ] She would instead kill her ain weak spirit so she could give me a stronger one ( 240 ) . An-mei s female parent believes that this is her lone solution and by making this, she ll be able to learn her girl to be stronger and happier than she will of all time be and that Wu-Tsing will populate a life full of guilt. This is the consequence of loss of hope, where a individual makes a lasting solution for a impermanent job because Wu-Tsing was non guilty of his incorrect behaviors, alternatively he is merely afraid of her spirit traveling after him. As for An-mei ; she was non happy because her female parent s decease brought her a more nice life, alternatively her female parent s tragic life and decease non merely took her artlessness off but have besides taught her to hold hope inste ad than being hopeless like her female parent. Rose Hsu Jordan, the girl of An-Mei Hsu. Al though her relationship position is really similar to her grandma s ( An- Mei s female parent ) , she really found her interior strength towards the terminal. Rose is married to Ted Jordan, who takes entire control over her. But when his occupation failed, he made Rose take up all the duties ; cognizing that Rose can non make up ones mind for herself, because she s been so dependent for so many old ages and the fact that she blames herself for her brother s decease made her even more insecure when doing determinations. When Ted requested a divorce, Rose s life started to alter. Being so dependent, providing to Ted wholly along, Rose s life jumbles apart. It was non until subsequently, that she realizes that she does non necessitate Ted to be able to last. We know that Rose goes through emotional phrases after her divorce with Ted When something that violent his you, you ca nt assist but lose your balance and autumn. And after you pick your self up, you realize you ca nt swear anybody to salvage you- non your hubby, non your female parent, non God. [ aˆÂ ¦ ] ( 121 ) , but the fact that Rose was able to pick herself up and confront her job after sing the resentment of her divorce and losing her artlessness, shows that she is at least following the constructs of hope, where she is perpetrating to go on with the battle instead than killing herself like her grandma. As we can see, hope is the foundation to construct one s life upon. Al though confronting many obstructions, An-Mei and her girl Rose were able to last the sorrowful events that happened in their lives, whereas An-Mei s female parent did non. They were able to see the construct of losing artlessness, but non trust , found their interior strength to confront their battles, learned from it and populate a more positive life.
