Causes and Impacts of Acid Rain

Causes and Impacts of Acid Rain Acid rain is an extensive dilemma faced by the world. The destructive outcomes of acid rain are one of the major contributors to this type of pollution. Acid rain is any rainfall; precipitation, snow, or fog that includes acids for instance nitrogen oxide and sulfur dioxide. Our society is engulfed with huge amounts of pollution from factories, cars, and garbage. The incredible quantities of sulfur dioxide released into the air, sources high levels of acid in the environment. Acid rain causes a stream of effects that kill or harm individual fish, lessen fish numbers population, entirely exterminate fish species from a water stream, and lessen biodiversity. Acid rain is sourced by a reaction of chemical that commences when composites similar to nitrogen oxides and sulfur dioxide are discharged into the air. These materials can go up extremely high into the environment, where they combine and retort with oxygen, water, and additional chemicals to structure additional acidic pollutants, identified as acid rain. Human activities are the major source of acid rain. Above the precedent few decades, humans beings have discharged so several diverse chemicals into the atmosphere that they have transformed the blend of gases in the environment. Power plants discharge the preponderance of sulfur dioxide and a great deal of the nitrogen oxides when they smolder fossil fuels, for instance coal, to create electricity. Additionally the exhaust from trucks, buses and cars, discharges sulfur dioxide into the atmosphere which source acid rain. In expressions of natural sources, equally decaying vegetation and volcanoes discharge gases that effect in the construction of acid rain. The terrific amounts of sulfur dioxide released into the air causes elevated levels of acid in the surroundings. Sulfur dioxide is mainly one of the vital constituents of acid rain and it helps maintain sunlight outside the atmosphere, which sources the Earth to cool Sulfur dioxide emission adds to global warming. The acidity of a substances suspended in water is normally computed in terms of Ph level. When this sulphuric acid is soaked up into humidity of the air, poignant rainfalls can be destructive to the outside environment. (Godbold, D. Huttermann, A.). Acid Rain can dissolve chalk and limestone, and oxidizes structures of outdoor. Monuments and Statues that are left unprotected can plunge casualty to the unprejudiced obliteration of acid rain. Acid Rain counters to diverse types of rocks soil and in two ways. Acid rain will melt alkaline soil and rocks, or will counteract the alkalinity. Acid rain will raise the acidity of previously acidic soil and rocks, for instance granite, or the soil which effects from oxidized granite. Natural sources, which release sulfur dioxide, are sea spray, volcanoes, rotting vegetation and plankton. Acid rain is obliterating the world’s air, lakes, and ecosystem. Acid rain affects each single feature of the ecosystem. Acid rain is distressing to crops, aquatic life, and forests, and human life. People exposed to sulfur dioxide in the air habitually have decreased lung function. It is a non point source of pollution. Pollution of Non point source is a structure of pollution which structures in an extremely extensive area and enters the polluted region in minute, dispersed flows. In view of the fact that acid rain structures in the sky, and descends to the earth a modest at a time, it is deemed a pollution of non point source. The expansion of forestlands as well demonstrates the outcomes of acid rain. Acidic rain damage trees (Godbold Huttermann,). Numerous trees illustrate the contamination gradually, on the other hand when disease and virus attacks they yield to the disease since of their weak conditions. Young plants with budding root systems are readily damaged by rainfall of acidic when pollutants penetrate the soil and are soaked up by the plants (Which, 2012). When acid rain happens, it doesnt right away affect acidity in lakes and streams. Lakes are very much affected by polluted precipitation. Acid depositions can have an unconstructive effect on our freshwater stream and lakes ecosystems by worsening the pH level of the water (Driscoll, C. T). â€Å"Numerous fish species are not capable to survive important changes in pH, and affected bodies of water might become devoid of any fish†. Approximately twenty thousand lakes have been turned acidic in the course of groundwater pollution by acid rain. A solution to lake acidity is liming. Lime is extremely alkaline, as a result when poured into lakes it annuls out the acidity (Godrick EC and Spilios KE (eds). 2011). The difficulty with liming is that it is extremely costly and only provisionally reduces acidity. (Driscoll, C. T)Currently that acid rain is extensively acknowledged all throughout the world; progressively people are doing something concerning it. We can alleviate the effects by means of an unconventional source of energy for instance batteries, wind power, solar, and electricity (What, 2013). Emissions of Fossil fuel source pollution and acid rain and are non-renewable and costly (What, 2013). An additional great source of energy is manpower; reflect on biking or walking to school or work. We can discontinue using gas-guzzler vehicles. This will help to save fuel and prevent pollution from escaping into the atmosphere. One person really can make a difference when they stop driving a non- fuel efficient automobile. Also by planting the trees will soak up a little of the polluted air and douse fresh clean, oxygen. (What, 2013). The 1963 Clean Air Act of US Federal control quality of air and that has lead to considerable progress on maintaining quality of air above the precedent years. This Act fetches strict restrictions on releases of acid rain-causing chemicals. Consequently, a lot of companies decreased emission of polluting oxides by levering from the employ of high sulfur coal to low sulfur coal, which manufactures a reduced amount of oxides when burned. (Anne T. Lawrence) Regulation, Technology, and consumer choices can all participate a function in reducing the force of energy use on the air we inhale. The U.S. Congress in 1990, generated the Acid Rain Program inside the Clean Air Act of federal to diminish the unpleasant acid rain effects in the course of yearly reductions in nitrogen oxides and sulfur dioxide from power plants that smolder fossil fuels. These and additional discharge reductions have lead to a major decline in acid deposition. Like a lot of other environmental issues related to energy, air pollution can be decreased in the course of energy efficient and maintenance improvements, both at the industry and consumer level.

Classifications of Liquid Crystals

Classifications of Liquid Crystals 1. Introduction 1. Introduction to Liquid Crystals 1.1 Historical background Liquid crystals are a unique state of matter, between solid (crystalline) and liquid (isotropic) phases some compounds form a distinct, different intermediate phase, sometimes referred to as the â€Å"fourth state of matter† or â€Å"mesophase†. These compounds display properties of both solid and liquid. Anisotropic intermolecular interactions of the molecules, or mesogens, within a liquid crystalline material mean that the molecules possess some orientational or positional order but with a lower degree of organisation compared with a crystalline solid. This means liquid crystals possess liquid-like flowing behaviour, but because of their positional order, such compounds are often more viscous. Liquid crystals are attributed to their sensitivity to various stimuli, such as temperature, electric and magnetic fields. This sensitivity, combined with the self-assembling behaviour of liquid crystals make them extremely interesting and fascinating for chemists and physicists . Friedrich Reinitzer, a botanist at the Karl-Ferdinands-Università ¤t was the first to discover and publish work on liquid crystals[1] in 1888. In this paper he described the melting phenomena of cholesterol benzoate, in which there were two melting points; the compound transforms into a cloudy fluid at 145.5  °C which became clear at 178.5  °C.[1] Reinitzer could not explain these observations, so he sought help from physicist Otto Lehmann, an expert in polarisation microscopy. Lehmann investigated the optical properties of the compound and found crystallites in the cloudy fluid, and observed this to be an intermediate phase (or â€Å"mesophase† – from Ancient Greek,ÃŽ ¼ÃƒÅ½Ã‚ ­ÃÆ'ÃŽ ¿Ãâ€š (mà ©sos) meaning â€Å"middle†) between the liquid and solid phase. This intermediate phase showed birefringence but also flowed like a liquid.[2] In 1904, Lehmann was the first to coin the term â€Å"Liquid crystal† for these types of compounds. Vorlà ¤nder, a German chemist, was another pioneer in liquid crystal research and he discovered that molecular shape was very important in the geometry of the mesophase.[3] In 1935 Vorlà ¤nder retired but due to his research most of the liquid crystals up this date had been synthesised by him. For a long time liquid crystals were merely scientific curiosity.[4] The unique properties of liquid crystals together with some molecules being sensitive to electric fields, began the research by Heilmeier[5] in 1968 which led to the discovery and widespread applications in liquid crystal displays (LCDs).[6][7][8][9][10][11] 1.2 Classifying Liquid Crystals Liquid crystals are classified in many ways,[12][13] molecules within the mesophases (mesogens) can be calamitic (rod-like), discotic (disc-like), amphiphilic, nonamphiphilic, metal containing, non-metal containing and low molecular weight or polymeric. Liquid crystals either show thermotropic behaviour or lyotropic behaviour. Thermotropic behaviour means the compounds are liquid crystalline within a defined temperature range, below this range compounds are crystalline and above it compounds are isotropic liquids (figure 1). Thermotropic liquid crystalline compounds also require no solvent. Lyotropic liquid crystals are dependent on solvents, where solvent concentration affects aggregation and liquid crystal behaviour. Figure 1: Rod-like (calamitic) molecules representing molecular arrangement of thermotropic liquid crystalline phase transitions. This work is focused on calamitic, thermotropic liquid crystals. Mesophases of such liquid crystals can be divided into categories which depend on the orientation and order. The main categories are nematic (N), smectic (Sm) and cholesteric (N*) (or chiral nematic) (figure 2). Figure 2: Molecular arrangements of different sub-phase allignments. 1.2.2 Nematic Phases The nematic phase is the simplest mesophase known; there is long range orientational order between the mesogens but no short range positional order. Mesogens are able to freely translate and rotate along the director field (n) but are randomly distributed in space. â€Å"Nematic† comes from the Ancient Greek word ÃŽ ½ÃŽ µÃŽ ¼ÃŽ ± (â€Å"nema† meaning thread) as when observed through a microscope thread-like structures are observed. 1.2.1 Smectic Phases Liquid crystals with smectic mesophases were originally discovered from amphiphilic molecules, the phase type coming from the Ancient Greek word ÏÆ'ÃŽ ¼ÃŽ µÃŽ ºÃâ€žÃŽ ¿ÃÆ' (â€Å"smektos† meaning soap-like). Today, the word smectic is used for liquid crystals in which the molecules occupy orientational order, but are also organised in layers[14]. These organised layers can slide relative to each other, which contributes to the liquid character of the liquid crystal phase. Many smectic phases have been discovered, each smectic phase differs in the orientation and position of the mesogens.[15] Smectic phases are distinguished by letters; SmA, SmB, SmC etc. with SmA and SmC being the most common. Smectic phases are distinguished via the molecular orientation within the layers (figure 2).[16][17] Smectic A (SmA) mesophases have molecules aligned along a director field (n) and are parallel to the layer normal and in smectic C (SmC) mesophases the molecules are tilted at a certai n angle away from the layer normal.[17] Compounds exhibiting smectic mesophases are sometimes referred to as two dimensional liquids, since there is no positional order within each layer.[14] 1.2.3 Cholesteric Phases The cholesteric phase is the nematic phase only mesogens change orientation in a helical manner with respect to the director field (n). The director field in the cholesteric phase changes direction and is perpendicular to the direction of the helix. The chirality comes from the molecules orienting themselves into a helix; each layer is non-superimposable. Within the cholesteric mesophase is the pitch, which is defined as the distance between one mesogenic layer and another which has rotated 360  ° to the director field (figure 3). Figure 3: Representation of the cholesteric mesophase with the cholesteric pitch. The first observed liquid crystals based on cholesterol derivatives showed this mesophase type, which is where the mesophase name â€Å"cholesteric† originates.[1][2] 1.2.4 Chiral Liquid Crystals There are 3 main types of chiral liquid crystals. The first type was found with cholesterol benzoate (the first liquid crystal discovery) in which the molecule contains one or more stereocentres. These form liquid crystals with helical order in the mesophase. The second type contains two molecules; a chiral guest molecule and an achiral nematic molecule. These molecules are mixed together to form chiral cholesteric structures. In the third type, mesogens layer themselves perpendicular to each other forming a helix or twist. These molecules do not need to be chiral, as the perpendicular stacking form helixes, giving this third type the name twisted nematic. Twisted nematic phases are found in liquid crystal displays and chiral liquid crystals overall are useful in the field of stereochemistry, optics and material science.[12] 1.3 Ionic Liquid Crystals Knight and Shaw were the first to discover liquid crystals which were ionic in 1938; the compounds had a pyridinium cationic core and flexible alkyl chains attached.[18] Ionic liquid crystals possess properties characteristic of liquid crystals (molecular order, mobility, anisotropy of physical properties) and ionic liquids (conductivity, thermal stability)[19] making them very interesting and useful for ion conduction (aligned ionic liquids[20][21]), electroluminescence (which can be used in organic light emitting diodes), manufacturing of displays[10], spatial light modulators[22], optical connectors and switches[23], molecular sensors and detectors[24][25] References [1] F.

Genetically Transgenic Crops :: Argumentative Persuasive Farming Essays Papers

Genetically Transgenic Crops In today’s society, farming has become far more complicated than one could imagine. In farming, the procedure involves a lot more than the raising of cattle and the planting of specific seeds into the soil or land fields. Yes, there is a lot more to worry about besides just the physical aspect of it. There are also decisions which have to be made in order to begin farming correctly and safely. Decisions which pose the question of should, and will the transgenic crops process be followed through nationwide? Our population may not even realize it; but the much needed decisions as this that will determine the fate of our world as we know it. At the cutting edge of technology and science, there seems to be a large debate about whether or not commercial plantings of transgenic crops are allowed. This is the issue at hand. One of the countries facing this conflict is Britain. The situation in Britain is just like the article written by Jim Giles which is titled, â€Å"Damned if they do damned if they don’t†. This article basically states that there is a huge problem with the idea of genetically modified crops being supported. I feel that his opinion on the subject matters, just as my scientific opinion does, because it is the population of the people that truly matters. The government wants to support the biotech industry, but on the other hand, it also wants to appease its closest ally, which happens to be the United States. Commercial cultivation of genetically, modified crops is an argument that is said to have been played out in Britain over any other country. In Britain, the government has prepared for decision time by conducting the largest trial of genetically modified crops ever, and they are looking forward to gathering as much evidence about their impact on biodiversity as possible. The outcome is bound to influence the debate in other countries where similar skirmishes are taking place. In the developing world, there are some areas that are for transgenic crops; such as sub-Saharan Africa which is emerging as an important new battleground. Other’s are not sure if they are for it or not; and a few are India and China. As a matter of fact, they are not even really concerned about this issue, but more concerned about whether or not the transgenic technologies will be from agribiotech or home-grown.

eli whitney Essay -- essays research papers

Eli Whitney   Ã‚  Ã‚  Ã‚  Ã‚  Before the invention of the cotton gin, Americans would remove cottonseed by hand. Slaves were hired to complete this procedure. This would take a very long time and something had to be done. Later on, a man named Eli Whitney invented a device called the cotton gin. The cotton gin is a machine for removing the seeds from cotton fiber. His invention could produce up to fifty pounds of cotton each day.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Eli Whitney was born in Westboro, Massachusetts in the year 1765.

He finally got accepted and graduated at the age of 27. When he graduated, he found that there were no jobs in engineering and decided to take on teaching. This also didn’t work out so he stayed on his friends’ cotton plantation. He found that the plantations were soon going to go bankrupt because of the high cost of producing cotton at such a slow pace. Many people realized that a device was ne...

Participation :: essays papers

Participation When the McDonald's patron in suburban Johnson County ordered a coffee and got a Coke, he came face to face with a Midwest labor pool truth. Non-English-speaking immigrants are an increasingly large part of the labor force -- not just in the Sun Belt states but in the upper Midwest as well. The fast-food worker, who spoke Spanish and had trouble understanding the man's order, was one of tens of thousands of Hispanics who entered the Midwest job market in the past decade. Without them, economists say, the long-running labor shortage, particularly in entry-level jobs, would be even more severe than it is. For some business patrons, the immigrant influx means occasional difficulties in communication. For some business owners, immigrant labor -- both documented and undocumented -- is the only way to fill jobs that otherwise would go begging. The most recent measure of unemployment in the Kansas City area, taken in May, was 2.8 percent. Missouri's jobless rate was 2.6 percent; Kansas' rate was 3.2 percent. Unemployment throughout the Midwest is well below 5.5 percent, which is considered full employment. Michael Barrera, president of the Hispanic Chamber of Commerce of Greater Kansas City, said the chamber had charted an explosive growth in the metropolitan area's Hispanic, blue-collar, minimum-wage work force, especially in Olathe and northeast Kansas City. Also, Barrera said, the 1990s brought a large increase in the number of entrepreneurial Hispanic immigrants, seen particularly in the blossoming of small stores and restaurants in Kansas City, Kan., and northeast Kansas City. The Hispanic chamber has no estimate of the size of the area's Hispanic work force, but Barrera said the Hispanic population may have grown to as many as 100,000, up from 58,000 in 1996. Throughout the Midwest, Hispanic immigrants are finding work. Census data, updated in 1998, found that 220,000 workers in the West North Central states were of Hispanic origin, up from 93,000 10 years earlier. The Census Bureau defines the West North Central region as Missouri, Kansas, Iowa, Nebraska, South Dakota, North Dakota and Minnesota. Similar findings were reported last week by the Bureau of National Affairs Inc. in its "Daily Labor Report 2000: Regional Outlook on Labor Markets." The bureau said Illinois now had the nation's fifth-largest Hispanic population, the highest ranking among states not in the Sun Belt. In Illinois and the other Midwest states, the bureau said, Hispanic immigrants are working in construction, restaurants, small manufacturing and farming.

Review of Literature of Risk Analysis in Portfolio Management

REVIEW OF LITERATURE * Ananth N Madhavan (2003) once a fairly esoteric subject, risk analysis and measurement have become a critical function for both portfolio managers and traders. Yet accurate measurement and analysis of risk presents many practical challenges, including the choice of risk model, portfolio optimization pitfalls, horizon mismatches, and out-of-sample testing. This detailed overview of recent developments in risk analysis and modeling focuses on practical applications. While risk management tools can provide invaluable insights as to portfolio risk, they must be applied with considerable care. Risk analysis, as it stands today, is as much an art as a science. * Peter Brooke (2009) suggested that  the easiest way to build a very diverse portfolio is via investment funds. The choice of funds is now enormous and nearly every asset class is covered by them. This means it is very easy and inexpensive to put several funds together and have a very broad spread. There are now some very good ‘multi asset' funds which provide exposure to all of these different classes in one professionally managed place. These multi asset managers may also be able to access some funds which are still not available to the retail investor, such as private equity. Peter Brooke is a financial planner to the English speaking expatriate community.

“Fools Tell All They Know” or The Wisdom of Feste in Shakespeare’s Twelfth Night

Almost all of Shakespeare's plays have a clown character. Clowns were popular and amusing, and were simple characters that the lower class audience members could relate to, amidst all the royal people plays were populated with. But the clowns in Shakespeare's plays served a dual purpose. Not only were they sources of comedy, but also sources of truth. Wisdom and advice are imparted through the lines of these figures of fun. The clowns reflected the true nature or intentions of the other, more â€Å"noble characters. They also foreshadow coming events. One of the most striking examples of this type of clown is the character of Feste in Twelfth Night. Feste dispenses advice and exposes truths to most of the major characters of the play. Though he is only a fool, he seems to be the only character in the play that truly has his wits about him. Feste mirrors each of the main characters, revealing facets of their respective dispositions. He often shares knowledge about other characters of which they were not aware. For example, Feste is most closely related to Olivia. She is his patron and calls upon him to amuse her. But Feste does not entertain in the standard way of a clown. He realizes that Olivia is not in control of her emotions when it comes to love, and that she lacks control over her subordinates. He says, in an aside, â€Å"Wit, an't be thy will, put me into good fooling! Those wits that think they have thee do very oft prove fools And I that am sure I lack thee may pass for a wise man. For what say Quinapalus? -‘Better a witty fool than a foolish wit.†' (1.5.29-31) Feste knows what is going on with Olivia's predicament with Orsino, but still plays the fool. He expresses his feelings of apprehension for Olivia and her supposed wisdom. Feste thinks Olivia's actions are silly, and is not afraid to tell her so in indirect ways. When Olivia gets tired of Feste's obscure advice, she tells her attendants to take away the fool, and Feste returns, â€Å"The lady bade take the fool away, therefore I say again/take her away . . . I wear not motley in my brain/good madonna give me leave to prove you a fool† (1.5.45-6, 49-51). He continues by asking Olivia why she mourns for the loss of her brother. If she believes his souls to be in heaven, as she does, then there is no reason for sorrow. Feste uses a sort of quirky pragmatism to try and show Olivia how silly she is being, but is does not work, because Olivia refuses to think of his advice as anything but the ramblings of a fool. Though Feste does seem, in some ways, to be very educated no one takes his suggestions seriously. Feste is the only character in the play that crosses into every world. He is privy to the secrets of Countess Olivia, he sings to and foretells the fate of Orsino, he guides Viola and Sebastian, Feste also ventures into the tavern world of Sir Toby, Sir Andrew, Fabian and Maria. Olivia bids him to enter this world by asking him to look after her kinsman, Sir Toby, who is a â€Å"drowned man,† that is to say, drowned with drink. Feste takes a lighter view of Sir Toby stat of mind by saying he is mad with drink claiming, â€Å"He is but mad yet, Madonna, and the fool shall look to the madman. In the context of the play, Sir Toby plays more the part of the classic fool than Feste. He is merely a comic figure with no more depth to him than that of the stock drunkard. Feste is the genius of the play, but is not noble, and so does not really fit in anywhere. Sir Toby and Sir Andrew treat Feste as both a friend and a servant, paying him to sing, but requesting his company and help i n their practical jokes. Feste reveals his foreknowledge about events to come in his song to Sir Toby, O mistress mine, where are you roaming? O stay and hear, your true love's coming That can sing both high and low Trip no further pretty sweeting Journey's end in Lover's meeting Every wise man's son doth know.† (2.3.36-40) Feste reveals to these two drunkards the plot of the entire play. Of course, they do not understand and simply praise Feste's singing ability, but, nevertheless, he has revealed his wisdom and knowledge about the other characters. Later in the play, they request that Feste dress up as a wise man to fool Malvolio into thinking he has lost his wits. Feste humbly obliges and does so, playing the part willingly and well. Shakespeare's characters love to disguise themselves; this theme is often important to the plot of his comedies, but in this case, the disguise takes an ironic turn. Feste, in dressing up as a wise man, reveals his true nature instead of concealing it. Though this scene is meant to be played for bald comedic value, the audience gets a glimpse of the true nature of the clown. Truly, though, Feste does not seem very interested in the torment of Malvolio, and ultimately provides him with means to resolve his unfair predicament. â€Å"Look then to be well edified when the f ool delivers the madman,† Feste says as he reads the letter that leads to Malvolio's release from captivity. Feste is also aware of the fate that will befall Orsino. He is welcome3d to the music-loving court at Orsino's home, perhaps because he belongs to Olivia, and in this way, at least, Orsino can feel he has some sort of relationship with her. Feste quickly sees through Orsino's melancholy and wishes, Now the melancholy god protect thee, and the tailor make thy doublet of changeable taffeta, for thy mind is a very opal. I would have men of such constancy put to sea, that their business might be everything, and their intent everywhere, for that's it that always makes a good voyage of nothing.† (2.4.72-6) Feste knows exactly what Orsino is feeling, how his relationship with Olivia is shaping up, and what his final result will be. Orsino is fickle and shallow and Feste knows it. When Orsino and Feste meet again later in the play, Feste is resentful of his patronage, wishing â€Å"the worse for his friends,† then calling Orsino his friend (5.1.10,22). Clearly, like the audience, Feste does not care for the Duke Orsino. Feste reveals his wisdom most clearly in his conversations with Viola. Though he refers to her as â€Å"sir,† he does so in a sarcastic way, as if he knows her secret. Viola also forces Feste to consider his own circumstances, and he meditates, â€Å"A sentence is but a chev'ril glove to a good wit-how quickly the wrong side may be turned outward,† and Viola counters with, â€Å"Nay, that's certain. They that dally nicely with words may quickly make them wanton,† (3.1.10-14). Since Feste is an actor, Shakespeare is playing with the meaning of these lines in one of his favorite ways, by reminding the audience they are watching a play. These two are certainly the most charming characters of the play and their dialogue reveals as much. Both know a little about the other's true nature, and are not afraid to share their knowledge with each other. Feste prefers Viola (as Cesario) to Orsino as a suitor for his mistress, and so tries to help win her, and mistakenly, Sebastian, to Olivia's favor. Feste seems to grow tired of his fool's role in the play. By Act three he declares, â€Å"Words are grown so false, I am lost to make reason with them,† (3.1.22-3). He has an air of resignation in his lines towards the end of the play, ultimately leading up to his final epilogue. This song chronicles his life, in a melancholy way, ending with, † But that's all one, our play is done/ And we'll strive to please you every day.† Feste's final words are riddled with melancholy; he is doomed to always play the fool, to never be free of the constraints of the play. As a fool, Feste has all the necessary qualities: singing, impersonation, joke-telling. But, as a character, he is much more than a jester. He is the key to Twelfth Night. He gives the play depth and substance that other comedies do not contain. He weaves all the worlds of the play together with witty words and melancholy ballads. Feste is the binding element in an otherwise contrived and ordinary play.
