The Matrix :: essays research papers

The Matrix, The â€Å"Western† Never Known   Ã‚  Ã‚  Ã‚  Ã‚  As stated by the title, there is great reason why the Matrix should be treated in the same context, although not identified, as a western. This film genre is steeped in tradition and lore. There are many definitions abound as to what may constitute a â€Å"Western film.† The main goal is to see whether or not this paper can illustrate the genre be pushed towards the future. Whether it means the 20th century, the 21st century or the distant future. This genre can grow towards something bigger and more exciting. This paper will attempt to explore this debate and give reasoning’s as to what defines a Western, how the Matrix lives up to and modifies the stated definition, will go into the films background such as director, producer, film reviews, etc. Finally the paper will discuss the theme, tone, setting, characters and casting, acting style, lighting, imagery, musical score, and special effects.   Ã‚  Ã‚  Ã‚  Ã‚  Defining a film genre is in some ways difficult and simplistic. Every genre has stated what would define its boundaries. The difficult part is finding one that is solidified by the movies in the genre. The stated definition that this paper will digest and regurgitate is that a Western is a film which is set in the American frontier west. The typical time setting is somewhere in the mid to late 19th century and early 20th century(Dirks, 1). They glorify the past-fading values and aspirations of the mythical by-gone age of the American West(Dirks, 1). Over time, however, Westerns have been redefined, re-invented and expanded, dismissed, re-discovered, and spoofed. This actually makes the definition more lucid, making other films flexible enough to fit quite nicely into the genre.   Ã‚  Ã‚  Ã‚  Ã‚  Westerns also state that these films represent the ideals of a growing nation. Expanding and maintaining established territories is what is at the heart of older Western films as â€Å"Manifest Destiny† puts up in dialogue constantly. This particular fact is a main point which will be revisited. Dominating the unknown and uprooting natives or peoples who have been established long before the conquerors.   Ã‚  Ã‚  Ã‚  Ã‚  There are many central conflicts in old westerns. The battle between good and evil is the most common. Others include man vs. man, east vs. west, human vs. nature, or in the Matrix’s case, man vs. machine.   Ã‚  Ã‚  Ã‚  Ã‚  Does the Matrix live up to these ideals of a Western? Yes, in more ways than one.

Bromobenzene Essay

Introduction: The chemical reaction of nitration consists of a nitro group being added to or substituted in a molecule. Nitration can basically be carried out by a mixture of concentrated nitric acid and sulfuric acid; this mixture is useful to obtain the active nitronium ion. Electrophilic aromatic substitution is a method used when a functional group is needed to be substituted on to an aromatic compound. In the nitration, nitronium ion acts as the electrophile that involves the attack of the electron-rich benzene ring. Aromatic substitution is electrophilic, due to the high density in benzene ring. Benzene ring is one of the components in most important natural products and other useful products. The species reacting with the aromatic ring is usually a positive ion or the end of a dipole. Nitration is one of the most important examples of electrophilic substitution. The electrophile in nitration is the nitronium ion which is generated from nitric acid by protonation and loss of water, using sulfuric acid as the dehydrating agents. Data: Weight (grams) Beaker 39.1 grams Beaker + Crystals 41.9 grams Weight of Crystals (Prior to Addition of Ethanol) 2.8 grams Figure 1: This table illustrates the weight of the crystals that were formed before the ethanol was added. 2.8 grams x 5= 14 mL – This is the amount of ethanol that is needed to just dissolve the bromonitrobenzenes at 78.2oC. Weight (grams) Wet Sample of Crystals 1.40 grams Dry Sample of Crystals 0.95 grams Difference Between Wet and Dry Samples 0.45 grams Figure 2: This table illustrates the weight of the crystals that were formed as the final product. The wet sample and dry sample both have a different value. Figure 3: This is the structure of bromobenzene; this was the liquid that was given for this laboratory experiment. Figure 4: Mechanism for the formation of 4-bromonitrobenzene. Observations: When the bromobenzene was added, the solution turned yellow. The final product was also yellow crystals. Calculations: a. Bromobenzene 0.0142 mol bromobenzene b. Nitric Acid 0.090 mol nitric acid THEREFORE, IT CAN BE SAID THAT BROMOBENZENE IS THE LIMITING REAGENT c. Actual Yield and Percent Yield 33% THE PERCENT YIELD IS 33%. Conclusion: It can be said that the objective of this experiment was to synthesize the p-bromonitrobenzene out of bromobenzene by nitration. This experiment studied the electrophilic aromatic nitration of a monosubstituted aromatic cring under a standard set of conditions. Electrophilic aromatic substitution is the addition of a nitro ( NO2+) group to an aromatic ring. When the aromatic ring is monosubstituted (meaning it already has one substituent on it), the nitro group can be added to either the: ortho, meta, or para position. Figure 1 illustrates the weight of the crystals prior to the addition of ethanol. The weight of the crystals before the ethanol was added was 2.8 grams. These were the crystals that were formed when the nitric acid and sulfuric acid mixture was slowly added to the bromobenzene. The weights of the crystals were determined before the addition of ethanol; this was important to do in order to find the amount (mL) of ethanol to add. The weight of the crystals was 2.8 grams and was multiplied by 5 to get 14mL; this was the amount of ethanol that was added. The ethanol was added to the crystals to dissolve the bromonitrobenzenes at 78.2oC. Figure 2 illustrates the weight of the wet crystals and the dry crystals. The weight of the wet crystals was 1.40 grams and the weight of the dry crystals was 0.95 grams. The difference between these two weights was 0.45 grams. The number for the dry crystal was then later used to determine the actual yield and the percent yield of the laboratory experiment.. The moles of bromobenzene were calculated to be 0.0142 moles. The moles of nitric acid were calculated to be 0.090 moles. Therefore, since the moles of bromobenzene were lower than the moles of nitric acid, it can be said that bromobenzene is the limiting reagent. After the limiting reagent is found, it is used to find the theoretical reagent. Questions: 1. What products did you expect this reaction to form? Explain the effect that the group(s) present in the starting material have on reactivity and orientation in this reaction and why. There were two possible products that could have been formed in this experiment. The first product that could have formed was 1-bromo-2-nitrobenzene and the second product that could have formed was 1-bromo-4-nitrobenzene. These were the two products that could have been formed because bromine is in an ortho and para directing group.

Global Climate Summit With Billionaire Bill Gates - 951 Words

World leaders comprising of prime ministers and presidents of the globe’s most powerful nations shared the spotlight of an international Climate summit with billionaire Bill Gates. Set in the capital city of France, the summit has the potential to unite politicians from across the world, on topics of fossil fuels and nuclear power, in hopes of remedying the impending global climate crisis. An essential issue is that the only assemblage of citizens in Paris attempting to disrupt the energy sector’s business plans, are an informal club of 28 private investors who have formed a taskforce called the Breakthrough Energy Coalition, led by none other than Microsoft-founder and entrepreneur Bill Gates. This coalition which has the backing of billions of dollars of committed research and development funding, have agreed that energy and research development is a worthy beneficiary of their various stock profits. Much of the issue of the globe’s current power economy is th at many countries have a large stake in their archaic power sources, most notably the widespread use of coal, such as coal making up 80% of China’s primary energy source for a country that contributes 20% of global Carbon dioxide emissions. Gates and his colleagues understand this predicament, and their contributions have assisted in convincing 20 governments to commit to doubling their own funding towards energy research. Upon the discovery of new energy methods, the state of the earth’s power scheme will not turnShow MoreRelatedOne Significant Change That Has Occurred in the World Between 1900 and 2005.
