Personal Values And Ethics Of An Italian Essay Example for Free

Personal Values And Ethics Of An Italian Essay Values are defined as â€Å"the deepest beliefs and we sentiments we subscribe to†. Every person has values that they put into practice in their lives whether they realize this or not in other words we all apply values in our day-to-day lives both consciously and unconsciously. An individuals’ set of personal values guides him or her on how to live his or her life. Once these values have been implemented, they enable the implementer to achieve great things in life that they would otherwise not have been able to accomplish. Once an individual has implemented his or her personal values in his or her life, these values then energizes the individual and enables him or her to tackle issues that were previously seen as impossible in other words personal values allow an individual achieve what they dream of. Once a person has identified the values that are important to them they go further and develop strategies to be used in implementation of these values. Upon implementation, these values are said to be able to work wonders in a person’s life in that the person now has a direction in life that guides them in making decisions that are in line with their overall aim. When one identifies a mission philosophy or belief that is meaningful to them in their lives, then that becomes their value. There many categories of values whereby they are ranked as either commonplace or those that is special and psychological. An individual day-to-day life including relations with others and how they approach their work is determined by their personal values. These values are the ones that determine the success of an individual in whether action they dedicate themselves to. Once they are applied it becomes very easy for the person to excel in the workplace and personal life. They are said to have the ability to multiply the impact of an action and in turn the consequences of the act. Italians are very religious people and the biggest percentages of them are Catholics. They follow the tenets of the Catholic Church very strictly. They are very emphatic on the importance of the family and especially the mothers. They come together as families as often as possible and even conduct their businesses as a family. The men are always seen as the bread winners in the house and the women are to take care of the family in all ways. Being brought up in such a setting has shaped my values in to confirming with a lot of the traditional that I found when I was born and grew up in. In 1884, the Italian Republic made an agreement with the Vatican regarding religious education in schools. There was then a provision made that ensured that there would be religious teachings offered in all schools that are below the university level (http://www. beginningwithi. com). Since Italy is a catholic state, it therefore means that these teachings are mostly catholic in nature. This therefore ensures that all Italians who are born and bred in Italy have an option of getting religious teachings in school. It was however noted that not everyone is a catholic or even a Christian. This then led to need to make these teachings optional to those who wanted to learn. Those whose parents did not want them to learn had an option of refusing to allow their children not to learn. Since my family was and still is a very strict catholic follower, I never had the option to even refuse to attend these lessons. In fact this was seen as an added advantage since I would be able to learn more about Jesus Christ and the Virgin Mary alongside the various teachings found in the bible. This would in the long run make me a better Christian and it actually did. Having grown up in a catholic family and also an extended one made my personal values to develop in a way that enables me cope with then. My personal values include success commitment fairness faith family feeling hard work and tolerance. The church I have grown up in has taught me to have faith in what I do and in god and hop that all will end well. This has sustained me all through my life especially at times when I feel emotional and psychologically unstable. At these moments I prefer to go to church and say prayers to calm me down. It has also taught me to be committed and this is what has enabled me to hold one position for 15 years in the same store. In Italian culture, one tends to live with the extended family and this is expected of all people. It is customary for the grandparents to care for their grandchildren which they d thus one has to cope with having a house full of relatives and this makes one tolerant. This has gone a long way in enabling me work with other employees without losing my temper. In under standing their weaknesses I am able to correct them without causing the formation of negative altitude towards me and weakness I am able to correct them without causing the formation of negative altitudes towards the job and me. When correcting their mistakes, I do so just as I would if it were my family member and this makes them feel appreciated and thus workers are motivated. I am currently studying for my B. S in criminal justice. The desire to study this course was prompted by my belief in fairness. I have a very strong conviction that everybody of what his or her previous life has been like. As a Christian I believe that any person can change given the chance. It is also true that there are quite a number of people who are wrongfully accused and convicted and it is necessary to correct such wrongs. By learning the different theories propounded in the course study. I can be able to use them in my workplace and in my day-to-day life to blame where it his not due I avoid unnecessary confrontations with other people. In my 15 years of working at the Vons Grocery store, I have met a number of personalities made a positive impact in my life. Michelle Valverda and Shielha Mosley. These people have taught me how to deal with other employees in order to maximize their output. They have taught me the value of success. It has been clarified in my mind what success really means and not just in monetary terms but also in emotional, psychological and physical well-being. These two people have reminded me the importance of leading a round life without neglecting any part of my life since all are important and are required in measuring the success of an individual. When I joined college to study for the criminal justice course, I met other people who added to my list of personal values. One of them is Ian Barrimond who is a fellow student. He has strengthened my value of tolerance because he is becoming more enjoyable when I do not keep getting angry with people for minor mistakes. Furthermore Ian is really committed to his studies and thus has introduced a new value to my life that is commitments. Apart from attending college he has a very demanding job that does not leave him with much time for himself yet he still manages to find time to dedicate his studies. My teacher is also a major influence to my list of values since he is always insisting on the necessary of hard work. Steven Fraitas insists that only by hard work can one be able to achieve what they want from life. The other major influences in my life are my parents who have always insisted on the family unity. They have never allowed my siblings and I to be on bad terms with each other for long and they have always ensured that any problem that crops up among us is quickly resolved before it goes too far. Also they have used the many family gatherings that we hold to invite all of us including the members of the extended family to make sure that we all remain close. None of us feels like a stranger or outsider because we have never been allowed to have time to drift apart to a point of becoming strangers to each other emotionally. This has made me become even more committed to my own family in the hope that it will be as unified as the family that I grew up in. I work hard so as to provide for my family and make sure that they live as comfortably as I can make them. This is encompassed in the value of family feeling. In Italian culture, one tends to live with their parents long after they have reached the age of maturity (Giannotti E. Rocchi R. 2004). It has been argued by some people that this makes them vulnerable to emotional and mental instability. I beg to differ with this conclusion because instead of destabilizing me this has made me a stronger person in aspects in life. There is an assumption that we should all be married at a certain age but by waiting until the right moment allows one to be able to choose the right partner in life. This is important because in the catholic church one is not allowed to divorce and thus it is necessary to choose someone who one will be able to stay with for the rest of their lives. I am among those people who lived with their parents long after the time that is set as standard for people to move out of their parent’s house. I can testify to the benefits that I reaped from this. Since almost all my brothers and sisters were also living with my parents, we were able to develop our relationship into our adulthood. Not only have we remained close with my brothers and sisters but also with my parents. Since I did not start my family until I was old enough to appreciate what I needed in a spouse, I am then able to treat my spouse the way it has always been in the Italian culture. I was also able to learn a lot from my parents on how to live in peace and harmony in the same house with your spouse.

No Country For Old Men By Cormac Mccarthy English Literature Essay

No Country For Old Men By Cormac Mccarthy English Literature Essay The novel No Country for Old Men by Cormac McCarthy uses symbolism and the world of the characters to support one of its many themes of the novel. Not only that, but through symbolism, McCarthy reveals the character traits and motives of each of the characters, mainly Moss and Chigurh. The journey of Llewellyn Moss and his attempts to escape the psychotic killer Chigurh symbolizes the fact that you must keep on going to escape the ever changing world. The actions of Chigurh also tell the readers that amongst our sweet, beautiful world, there is so much evil, greed, and death lurking and no matter how hard people try, there is no escape. Through the developments of characters as they are in the novel, and with the help of many symbols, McCarthy effectively conveys the message of No Country for Old Men. The title of the novel itself signifies one of the themes very well which is that one must keep running because if the ever changing world catches up to you, it will devour them. The quote survival of the fittest as said by Charles Darwin applies to this real well. For example, an example straight from the story is how Moss finds the suitcase with two million dollars in it, and is on the run thereafter, from the psychotic killer Chigurh. Where ever he goes, Chigurh gets there and finds him. This is an example of how the world is always changing and if even for a second, a person thinks they are not going to be a victim of it they are wrong. As the story progresses, Chigurh finally catches up with Moss and kills him. This tells the readers that as soon as you think you have won against the world, it will get you really hard. This theme also relates to the title of the story really well in the sense that it says that this is no country for old mean. How this relates is when people get old, they cannot stay up with the race against the world, and one day, the world overtakes them, and they meet their end. It may be the authors take on how life and death works. Another prominent character in the story, Sheriff Ed Tom Bell who is out to hunt for Chigurh plays a great role in signifying the theme mentioned in the above paragraph. Like Moss is on the run from Chigurh, Chigurh is on the run from Sheriff whether he knows it or not. This proves that it does not matter who you are and what you may do, the cycle of life, and the moving world applies to you too. How this applies to the Sheriff himself is really clear in the novel. Throughout the novel, he talks about how he is getting old and he wants to retire through big passages at the beginning of each chapter. He makes remarks about how the world has been changing so quickly, and becoming into a dark, scary place. He mentions that law enforcement work is more dangerous now than what it used to be and this is referring to the world of law enforcement, which is his world because he has been a sheriff since a really young age (McCarthy, 38). So what he is trying to say is that the world is a much more worse place not than before, which also points to the changing of it (the world), and it has changed for the worse. A point to be noted is the fact that he mentions how he is getting old and wants to retire. This goes back to the title of the novel itself. No country for old men. One more example of the prominence of the above theme is when Moss is on the run from Chigurh and is having dinner. He says three weeks ago I was a law abiding citizen. Workin nine to five jobs. Eight to four, anyways. Things happen to you they happen. They dont ask first. They dont require your permission (McCarthy 220). This quote is one of the single biggest proofs of the theme of a changing world in the book. This tells us how our choice, and decisions we make effects our life whether we know it or not, and we cannot do anything about it. Clearly, when Moss was making a choice of taking the money, he did not consider this. This tells the readers that whatever you do in the world will have its consequences and some you can avoid, and others you cannot but to do so, you must keep moving otherwise you will be caught and served justice. Along with that, another prominent theme of the novel is that there is nothing anyone can do about the evil side of human nature. This includes greed, violence, and cold hearted killing. Let us start off by talking about the protagonist, Llewellyn Moss. The actions of this man started off the whole chain of events, leading to numerous deaths. When Moss saw the drug deal gone wrong, instead of helping one of the wounded survivors out, he walks away, takes the 2 million dollars, and goes home. This triggers another event. Anton Chigurh sets out to find him, and wherever he goes, he leaves a trail of blood. When the Sheriff tells him he will help, he refuses and digs his grave even deeper. All of this is a result of the greed for money. Another example is that of Anton Chigurh the main antagonist. When Chigurh gets into a gun fight, he sees the lights receding. Watching his own image degrades in that squandered world (McCarthy, 122). This symbolizes the squandered world, being degraded to the point where people can kill very easily, and watch others die just as easily thereafter. The last quote mentioned also shows the contrast between the character of Moss and Chigurh. On one hand, there is Moss, who cannot kill Chigurh, even though he was right in front of him, knowing the fact that he is trying to kill him, no holds barred. On the other hand, there is Chigurh, who enjoys every single moment of killing people. Although what Moss did triggered so many murderous events, his actions throughout the book and lead us to say that he is not a bad person, though he may have made a few mistakes in his life. Going back to the beginning of the novel, when Moss finds the money case, and there is a man dying and asking for water. At that time, he does not have it so he goes back to get it and while coming so, says Im fixin to go do something dumbhern hell but Im going anyways (McCarthy, 24). He knows that going there is risky, but as a good person, he risks his life just to go and give a dying man some water and this is a really good sign of how great of a heart Moss possesses. Another example is later on when he is on the run. He says Three weeks ago I was a law abiding citizen. Workin nine to five jobs. Eight to four, anyways. Things happen to you they happen. They dont ask first. They dont require your permission(McCarthy, 220). He tells this to a girl who he is having dinner with. This shows his cha racter as a caring and nurturing one because he does not want the girl to make the mistakes he has made. This goes to show that no one on this planet is flawless. The actions of Anton Chigurh, from the start build his character as an evil, blood thirsty, and devilish person who will do anything to attain personal benefits. In the beginning of the story, Chigurh escapes from the clutches of a local Sheriff, and he place[s] his hand on the mans head like a faith healer [à ¢Ã¢â€š ¬Ã‚ ¦] The man slid soundlessly to the ground, a round hole in his forehead from which blood bubbles [à ¢Ã¢â€š ¬Ã‚ ¦] (McCarthy, 7). This quote, not only reveals Chigurhs character, but the fact that it is at the very beginning of the book, reveals the theme of violence, murder and violence throughout the story, and readers can very easily notice them. When Chigurh [à ¢Ã¢â€š ¬Ã‚ ¦] place[s] his hand on the mans head like a faith healer [à ¢Ã¢â€š ¬Ã‚ ¦], it reveals to the readers that Chigurh, despite being on a murderous rage, believes he had god given powers. Later in the novel, he weigh[s] things in his hand like a medium (McCarthy, 204) and this action of his is quite interesting because it paints divine light on the bloody character of Chigurh. Despite all the useless bloodshed caused by this fellow, he is portrayed as a greater being. Taking reference from Hindu philosophies, we can prove this to be correct. In Hinduism, a good person is the one who does his deed (karma) and bad people are the ones who slack away from it. Because of the fact that Chigurh is a killer, and he is killing people really well, McCarthy may have taken into account this philosophy, and painted Chigurh as an almost divine and great figure. By putting together all the different aspects of formalist approaches, we know that Cormac McCarthy is sending the readers of his novel, No Country for Old Men a deeper message than just the words. McCarthy wants to tell the readers that no matter what happens in life, you must keep moving forward, and never give up. This message can be taken by the readers no matter where they go in life and no matter how big of a person they become. Work Cited List No Country for Old Men Forums From Book to Film MovieWeb.com.

Other than that, my personal opinion and comment will also be in this chapter. Chapter 2 Literature Review 2.1 History of Solar Water Heating System Throughout human’s history the sun has always been a subject of guess and mystery. In fact, most ancient cultures have considered the sun as a god or godlike due to its life-giving and energy-giving. Thus, the subject of solar is one of the oldest subject for human. Besides that, it has gone through many evolutions and has been the subject of many schools of thought- starting with religion, and ending up in the field of science. It is impossible to exactly date the first uses of solar energy, it maybe the Egyptian, Chinese or even the Malay first invented solar energy. But we do know that ancient Greeks and Romans civilizations, made good use of passive solar energy in their building designs. The use of Solar Water Heating System has a surprisingly long history. Year 1891, Clarence M. Kemp became the first man to patent a Solar Water Heater, called the â€Å"Climax†(Bob Ramlow and Benjamin Nusz, 2006, p.2). It was a black painted water tank mounted in an insulated box with glass on one side. The Climax was instantly popular in California. Thousands of Climaxes and similar systems were installed in a short time. Figure 2. 1 An old advertisement for the Climax Solar Water Heater Year 1909, William J. Bailey, a California Engineer began selling a new system Solar Water Heater named â€Å"Day and Night†(Ramlow and Nusz, 2006, p.3). It consisted of a solar collector and a separate storage tank mounted above the collector. Year 1913, a freak cold snap hit southern California and many â€Å"Day and Night† Solar Water Heater collectors froze and burst. To terminate future freezing problem, Bailey installed a coil of pipe within the storage tank to act as a heat exchanger. Then he used an alcohol and water mixture as the antifreeze solution for his heat exchange medium. This system called as a â€Å"closed-loop† Solar Water Heating System. Year 1979, U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: â€Å"In the Year 2000, the solar heater behind me will still be here, supplying cheap, efficient energy. A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not taken; or it can be just a small part of the greatest and most exciting adventure ever undertaken by the American people.† (Ondrey, 2009). 2.2 Introduction of Solar Water Heating System One of the biggest uses of electricity, gas and oil is the heating of water in the home. Solar Water Heating System is a very simple and efficient way to grab energy from sun and use it. Solar Water Heater collects and converts solar radiation energy to useful thermal energy into the form of hot water. It essentially consists of solar collectors for absorbing and converting the solar energy and an insulated storage vessel or tank to contain the heated water. The amount of hot water a solar water heater produces depends on:- type and size of the system amount of sun available at the site seasonal hot water demand pattern and installation of the system Solar Water heater used in the homes for supplying domestic hot water are typically installed with some form of back-up heating system such as electricity to ensure a hot water supply during the night time and cloudy conditions. Solar water heater can be considered as per-heater. The Solar Water Heater raises the temperature of water before it enters the water tank. 2.3 Types of Solar Water Heating System There are two types of Solar Water Heating Systems, either is active or passive. Both of the types are working on the same principles. The only difference is active systems have a pump moving the water through the Solar Water Heating System but passive systems rely on nature principles which is warm water rises to the top, and cold water sinks to the bottom. With a passive Solar Water Heating System, the water storage tank must therefore always be positioned above the solar water heater collector. 2.3.1 Active Solar Water Heating System Active Solar Water Heaters rely on electric pumps, and the controllers to circulate water, or other heat-transfer fluids through the collectors. These are the types of Active Solar Water Heating System:- Open loop active systems- circulate water directly from the tank through the collectors (Morrison, 2005, p.226). This design is efficient and also can lower operating costs if there is no problem with the water supply because of calcium deposits quickly build up in the collector. Closed loop active systems- the heat transfer fluid is pumped through the collectors, and a heat exchanger is used to transfer heat from the collector loop to the water in the tank (Morrison, 2005, p.227). The two most common closed loop active  systems are:- Antifreeze- The heat transfer fluid is usually a glycol-water mixture with the glycol concentration depending on the expected minimum temperature. The glycol is usually food-grade propylene glycol because it is non-toxic. Drainback systems- A type of indirect system, use pump to circulate water through the collectors. The water in the collector loop drains into a reservoir tank when the pumps stop. This makes drainback systems a good choice in colder climates. Drainback systems must be carefully installed to assure that the piping always slopes downward, so that the water will completely drain from the piping. This can be difficult to achieve in some circulation. Active systems are usually more expensive and are less efficient than passive system of antifreeze measures are required. Active systems are more difficult to retrofit in houses that do not have basements because space must be found in house for additional equipment (Morrison, 2005, p.226). 2.3.2 Passive Solar Water Heating System Passive Solar Water Heaters rely on gravity and the tendency for water to naturally circulate as it is heated. Due to they contain no electric components, passive systems are generally more reliable, easier to maintain, and possibly have a longer work life than active systems. The two most popular types of passive systems are:- Integral-collector storage systems- combine tank and collector into one unit. These systems are simple and effective (Morrison, 2005, p.225). This system is only good in households with daytime and evening hot water needs due to high heat loss at night. The main limitation with this system concept is it is only a pre-heater and must be connected in series with a conventional water heater if a 24 hours hot water supply is required. Thermosyphon systems- an economical and reliable choice, especially in new homes. These systems rely on the natural circulation of water between the collector and the tank or heat exchanger (Morrison, 2005, p. 223). The tank set up must above the collector due to achieve circulation during daytime and also to limit reverse circulation at nighttime. Water which is heated will rise naturally into the tank and cooler water flows down to the bottom of the collector, causing circulation throughout system. 2.4 Pros and Cons of Solar Water Heating System 2.4.1 Advantages of Solar Water Heating System Installing a Solar Water Heater is an investment that will save our money for the coming years and it is simple to construct. It is almost free once the equipment is installed because of the â€Å"fuel† for the Solar Water Heater is getting from sun. Energy from the sun is renewable. So, we are protected from electricity bill increment year by year in the future. It is four times cheaper than electricity (Pandey and Banerjee, 1998, p.17). Besides that, it is environment free because it produces no greenhouse gases. Solar Water Heater avoids nitrogen oxides, carbon dioxide, sulphur dioxide and other air pollutants created when electric water heater is used to heat water. Solar Water Heater reduces pollutants and contribute to a healthier environment Other than that, Solar Water Heater is extremely safe and clean. We will feel free from the problem which will occur by electric water heater because Solar Water Heater mostly no maintenance, repair work or cleaning is required. By choosing a Solar Water Heater to heat water in home, it is an intelligent, socially aware and environmentally responsible energy source. 2.4.2 Disadvantages of Solar Water Heating System Although Solar Water Heating System consists of a lot of advantages, but it has its disadvantages also. First of all, Solar Water Heater will doesn’t work well on days when it is cloudy, over cast or raining. Besides that, it doesn’t work at nighttime. So, it is typically installed with electric water heater to ensure that hot water is supplied when the day is cloudy, overcast, raining or at night. Other than that, Cost of purchase Solar Water Heater is one the most critical issue. The initial cost of Solar Water Heater is high for Malaysian if compare to electric water heater. Many of the residents will not choose Solar Water heater due to its high initial cost. In addition, appearance of the house will affected due to the collector of Solar Water Heater is being installed on the roof. 2.5 Selecting a Solar Water Heater Before purchasing and installing a Solar Water Heating System, we are required to do the following:-  ·Ã‚  Consider into the economics of a Solar Water Heating System  ·Ã‚  Consider into the needs of hot water required  ·Ã‚  Determine the correct size for Solar Water Heating System  ·Ã‚  Determine the energy efficiency of Solar Water Heating System  ·Ã‚  Estimate and compare system costs 2.6 Method of Installation for Solar Water Heating System The installation of a Solar Water Heater requires skills that overlap many trades. Installer needs to be familiar with plumbing, roofing and electrical. Here will shows the various steps and processes to install a Solar Water Heater. This Solar Water Heating System consists of flat-plate collector, a differential controller, several sensors, a pump, and various valves. Step 1: Collector Mounting Before start the installation, installer must verify that the roof is suitable for the condition of mounting of the solar collector. Installer has to ensure that the roof tiles are in satisfactory condition and the trusses are adequate to support the collector. In general, there is no problem for installing a solar collector on a traditional roof. Besides that, it is recommended that the solar collector to face to south or within 30 º to 45  º east or west of due south. The installer needs to locate the trusses that will be use to attach the solar mounting brackets. After installer locates the trusses, he will then makes preparation for the installing of the collector mounting clips. The collector will then attach to the clips. Installer will carefully remove the roof tiles where the mounting clips will be installed. Four mounting clips will be used to support the collector and also to distribute the weight at the four mounting locations. Lastly, solar collector installs on the mounting clips. Step 2: Roof Pipe Flashing First of all, installer needs to identify and mark down the locations of the piping penetrations. There will be two penetration-collector feed line and collector return line. In gravity drain system, the feed line should penetrate the roof below the collector. Then, make a flat copper flashing with an oversize collar to penetrate the fluid line. Step 3: Piping from Tank to Collector Installer will install the pipe that will connect the water heater to the solar connector. Normally, soft copper will be used in the attic run between the tank area components and the collector lines exits at the roof because by using soft copper, installer does not have to solder any fittings in the attic. Pipe hangers will be used in locations to secure the long piping runs. Besides that, insulation will be installed on all attic piping to prevent heat loss. Step 4: Collector Feed line Piping Installer will measure, cut and fit the pipe fittings for proper length. He will solder the piping and fittings once all of them have been attached correctly. Step 5: Collector Return Line Plumbing Installer will solder fittings that will accommodate the system air vent. The system can prevent air locks that will restrict flow in the system. Air vent is always install at the high point of system and in a true north vertical position. Then, installer will solder more fitting such as pressure relief valve. Step 6: Storage Tank Installer starts the installation for storage tank. this involves plumbing the water heater for cold service, hot outlet, collector feed and return lines. Installer will place insulation on all exposed piping once the piping has been installed to reduce heat loss during system operation. Lastly, he will set the thermostat on the water heater because although the majority of the how water is produced by solar energy, but when cloudy, overcast or nighttime, the electric elements are always the spare for it. Step 7: Controller and Sensors Installer will install controller and sensor for the system. The differential controller is the brains of solar system. It works with two sensors. One of it located at the hottest part of the system which is collector outlet. The other one is located at the coldest part of the system which is the bottom of the tank. Step 8: Pump and Valves A Solar Water Heating System consists of a variety of components. System pump also called as circulator is a critical component for Solar Water Heating System. Its function is to circulate the fluid from the tank to the collector. Then the fluid gains heat in the solar collector and return to the storage tank. Besides that, check valve, drain valves and isolation valves also the components to install. Step 9: Pipe Insulation The last step for installation process is pipe insulation. It is to prevent heat loss from the piping, so pipe insulation is installed on both external and internal system piping. After that, installer should provide the owner of the Solar Water Heater a system operation and maintenance manual. 2.7 A Comparison between Solar Water Heater and Electric Water Heater Solartech (Summer) CX – Direct Heating* Panasonic DH – 3HE1M** Panasonic DH – 3HT1M** Type of Water Heater Solar Electric Electric Power Consumption 2.4 KW (back up heating element) 3.6 KW 3.6 KW Selling Price / unit RM 5,490.00 RM 639.00 RM 449.00 Selling Price (2 units) RM 1,278 RM 1,098 Initial Cost (selling price + installation cost) RM 5,690.00 RM 1428.00 RM 1248.00 Warranty (full warranty) 10 years 1 year 1 year Operation Cost / year RM 170.25 RM 1,109.67 RM 1,109.67 Operation Cost (10 years) RM 1702.50 RM 11,096.70 RM 11,096.70 Total Cost (initial cost + operation cost) for 10 years without maintenance cost RM 7,392.50 RM 12,374.70 RM 12,194.70 Environment Impact free CO2 CO2 Table 2. 1 Comparison between Solar Water Heater and Electric Water Heater * Description is given by Solartech Sales Service Sdn Bhd ** Description is given by Pansasonic Malaysia Sdn Bhd The table above shows the comparison between Solar Water Heater and Electric Water Heater.

Chapter 2 Literature Review 2.1 History of Solar Water Heating System Throughout human’s history the sun has always been a subject of guess and mystery. In fact, most ancient cultures have considered the sun as a god or godlike due to its life-giving and energy-giving. Thus, the subject of solar is one of the oldest subject for human. Besides that, it has gone through many evolutions and has been the subject of many schools of thought- starting with religion, and ending up in the field of science. It is impossible to exactly date the first uses of solar energy, it maybe the Egyptian, Chinese or even the Malay first invented solar energy. But we do know that ancient Greeks and Romans civilizations, made good use of passive solar energy in their building designs. The use of Solar Water Heating System has a surprisingly long history. Year 1891, Clarence M. Kemp became the first man to patent a Solar Water Heater, called the â€Å"Climax†(Bob Ramlow and Benjamin Nusz, 2006, p.2). It was a black painted water tank mounted in an insulated box with glass on one side. The Climax was instantly popular in California. Thousands of Climaxes and similar systems were installed in a short time. Figure 2. 1 An old advertisement for the Climax Solar Water Heater Year 1909, William J. Bailey, a California Engineer began selling a new system Solar Water Heater named â€Å"Day and Night†(Ramlow and Nusz, 2006, p.3). It consisted of a solar collector and a separate storage tank mounted above the collector. Year 1913, a freak cold snap hit southern California and many â€Å"Day and Night† Solar Water Heater collectors froze and burst. To terminate future freezing problem, Bailey installed a coil of pipe within the storage tank to act as a heat exchanger. Then he used an alcohol and water mixture as the antifreeze solution for his heat exchange medium. This system called as a â€Å"closed-loop† Solar Water Heating System. Year 1979, U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: â€Å"In the Year 2000, the solar heater behind me will still be here, supplying cheap, efficient energy. A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not taken; or it can be just a small part of the greatest and most exciting adventure ever undertaken by the American people.† (Ondrey, 2009). 2.2 Introduction of Solar Water Heating System One of the biggest uses of electricity, gas and oil is the heating of water in the home. Solar Water Heating System is a very simple and efficient way to grab energy from sun and use it. Solar Water Heater collects and converts solar radiation energy to useful thermal energy into the form of hot water. It essentially consists of solar collectors for absorbing and converting the solar energy and an insulated storage vessel or tank to contain the heated water. The amount of hot water a solar water heater produces depends on:- type and size of the system amount of sun available at the site seasonal hot water demand pattern and installation of the system Solar Water heater used in the homes for supplying domestic hot water are typically installed with some form of back-up heating system such as electricity to ensure a hot water supply during the night time and cloudy conditions. Solar water heater can be considered as per-heater. The Solar Water Heater raises the temperature of water before it enters the water tank. 2.3 Types of Solar Water Heating System There are two types of Solar Water Heating Systems, either is active or passive. Both of the types are working on the same principles. The only difference is active systems have a pump moving the water through the Solar Water Heating System but passive systems rely on nature principles which is warm water rises to the top, and cold water sinks to the bottom. With a passive Solar Water Heating System, the water storage tank must therefore always be positioned above the solar water heater collector. 2.3.1 Active Solar Water Heating System Active Solar Water Heaters rely on electric pumps, and the controllers to circulate water, or other heat-transfer fluids through the collectors. These are the types of Active Solar Water Heating System:- Open loop active systems- circulate water directly from the tank through the collectors (Morrison, 2005, p.226). This design is efficient and also can lower operating costs if there is no problem with the water supply because of calcium deposits quickly build up in the collector. Closed loop active systems- the heat transfer fluid is pumped through the collectors, and a heat exchanger is used to transfer heat from the collector loop to the water in the tank (Morrison, 2005, p.227). The two most common closed loop active  systems are:- Antifreeze- The heat transfer fluid is usually a glycol-water mixture with the glycol concentration depending on the expected minimum temperature. The glycol is usually food-grade propylene glycol because it is non-toxic. Drainback systems- A type of indirect system, use pump to circulate water through the collectors. The water in the collector loop drains into a reservoir tank when the pumps stop. This makes drainback systems a good choice in colder climates. Drainback systems must be carefully installed to assure that the piping always slopes downward, so that the water will completely drain from the piping. This can be difficult to achieve in some circulation. Active systems are usually more expensive and are less efficient than passive system of antifreeze measures are required. Active systems are more difficult to retrofit in houses that do not have basements because space must be found in house for additional equipment (Morrison, 2005, p.226). 2.3.2 Passive Solar Water Heating System Passive Solar Water Heaters rely on gravity and the tendency for water to naturally circulate as it is heated. Due to they contain no electric components, passive systems are generally more reliable, easier to maintain, and possibly have a longer work life than active systems. The two most popular types of passive systems are:- Integral-collector storage systems- combine tank and collector into one unit. These systems are simple and effective (Morrison, 2005, p.225). This system is only good in households with daytime and evening hot water needs due to high heat loss at night. The main limitation with this system concept is it is only a pre-heater and must be connected in series with a conventional water heater if a 24 hours hot water supply is required. Thermosyphon systems- an economical and reliable choice, especially in new homes. These systems rely on the natural circulation of water between the collector and the tank or heat exchanger (Morrison, 2005, p. 223). The tank set up must above the collector due to achieve circulation during daytime and also to limit reverse circulation at nighttime. Water which is heated will rise naturally into the tank and cooler water flows down to the bottom of the collector, causing circulation throughout system. 2.4 Pros and Cons of Solar Water Heating System 2.4.1 Advantages of Solar Water Heating System Installing a Solar Water Heater is an investment that will save our money for the coming years and it is simple to construct. It is almost free once the equipment is installed because of the â€Å"fuel† for the Solar Water Heater is getting from sun. Energy from the sun is renewable. So, we are protected from electricity bill increment year by year in the future. It is four times cheaper than electricity (Pandey and Banerjee, 1998, p.17). Besides that, it is environment free because it produces no greenhouse gases. Solar Water Heater avoids nitrogen oxides, carbon dioxide, sulphur dioxide and other air pollutants created when electric water heater is used to heat water. Solar Water Heater reduces pollutants and contribute to a healthier environment Other than that, Solar Water Heater is extremely safe and clean. We will feel free from the problem which will occur by electric water heater because Solar Water Heater mostly no maintenance, repair work or cleaning is required. By choosing a Solar Water Heater to heat water in home, it is an intelligent, socially aware and environmentally responsible energy source. 2.4.2 Disadvantages of Solar Water Heating System Although Solar Water Heating System consists of a lot of advantages, but it has its disadvantages also. First of all, Solar Water Heater will doesn’t work well on days when it is cloudy, over cast or raining. Besides that, it doesn’t work at nighttime. So, it is typically installed with electric water heater to ensure that hot water is supplied when the day is cloudy, overcast, raining or at night. Other than that, Cost of purchase Solar Water Heater is one the most critical issue. The initial cost of Solar Water Heater is high for Malaysian if compare to electric water heater. Many of the residents will not choose Solar Water heater due to its high initial cost. In addition, appearance of the house will affected due to the collector of Solar Water Heater is being installed on the roof. 2.5 Selecting a Solar Water Heater Before purchasing and installing a Solar Water Heating System, we are required to do the following:-  ·Ã‚  Consider into the economics of a Solar Water Heating System  ·Ã‚  Consider into the needs of hot water required  ·Ã‚  Determine the correct size for Solar Water Heating System  ·Ã‚  Determine the energy efficiency of Solar Water Heating System  ·Ã‚  Estimate and compare system costs 2.6 Method of Installation for Solar Water Heating System The installation of a Solar Water Heater requires skills that overlap many trades. Installer needs to be familiar with plumbing, roofing and electrical. Here will shows the various steps and processes to install a Solar Water Heater. This Solar Water Heating System consists of flat-plate collector, a differential controller, several sensors, a pump, and various valves. Step 1: Collector Mounting Before start the installation, installer must verify that the roof is suitable for the condition of mounting of the solar collector. Installer has to ensure that the roof tiles are in satisfactory condition and the trusses are adequate to support the collector. In general, there is no problem for installing a solar collector on a traditional roof. Besides that, it is recommended that the solar collector to face to south or within 30 º to 45  º east or west of due south. The installer needs to locate the trusses that will be use to attach the solar mounting brackets. After installer locates the trusses, he will then makes preparation for the installing of the collector mounting clips. The collector will then attach to the clips. Installer will carefully remove the roof tiles where the mounting clips will be installed. Four mounting clips will be used to support the collector and also to distribute the weight at the four mounting locations. Lastly, solar collector installs on the mounting clips. Step 2: Roof Pipe Flashing First of all, installer needs to identify and mark down the locations of the piping penetrations. There will be two penetration-collector feed line and collector return line. In gravity drain system, the feed line should penetrate the roof below the collector. Then, make a flat copper flashing with an oversize collar to penetrate the fluid line. Step 3: Piping from Tank to Collector Installer will install the pipe that will connect the water heater to the solar connector. Normally, soft copper will be used in the attic run between the tank area components and the collector lines exits at the roof because by using soft copper, installer does not have to solder any fittings in the attic. Pipe hangers will be used in locations to secure the long piping runs. Besides that, insulation will be installed on all attic piping to prevent heat loss. Step 4: Collector Feed line Piping Installer will measure, cut and fit the pipe fittings for proper length. He will solder the piping and fittings once all of them have been attached correctly. Step 5: Collector Return Line Plumbing Installer will solder fittings that will accommodate the system air vent. The system can prevent air locks that will restrict flow in the system. Air vent is always install at the high point of system and in a true north vertical position. Then, installer will solder more fitting such as pressure relief valve. Step 6: Storage Tank Installer starts the installation for storage tank. this involves plumbing the water heater for cold service, hot outlet, collector feed and return lines. Installer will place insulation on all exposed piping once the piping has been installed to reduce heat loss during system operation. Lastly, he will set the thermostat on the water heater because although the majority of the how water is produced by solar energy, but when cloudy, overcast or nighttime, the electric elements are always the spare for it. Step 7: Controller and Sensors Installer will install controller and sensor for the system. The differential controller is the brains of solar system. It works with two sensors. One of it located at the hottest part of the system which is collector outlet. The other one is located at the coldest part of the system which is the bottom of the tank. Step 8: Pump and Valves A Solar Water Heating System consists of a variety of components. System pump also called as circulator is a critical component for Solar Water Heating System. Its function is to circulate the fluid from the tank to the collector. Then the fluid gains heat in the solar collector and return to the storage tank. Besides that, check valve, drain valves and isolation valves also the components to install. Step 9: Pipe Insulation The last step for installation process is pipe insulation. It is to prevent heat loss from the piping, so pipe insulation is installed on both external and internal system piping. After that, installer should provide the owner of the Solar Water Heater a system operation and maintenance manual. 2.7 A Comparison between Solar Water Heater and Electric Water Heater Solartech (Summer) CX – Direct Heating* Panasonic DH – 3HE1M** Panasonic DH – 3HT1M** Type of Water Heater Solar Electric Electric Power Consumption 2.4 KW (back up heating element) 3.6 KW 3.6 KW Selling Price / unit RM 5,490.00 RM 639.00 RM 449.00 Selling Price (2 units) RM 1,278 RM 1,098 Initial Cost (selling price + installation cost) RM 5,690.00 RM 1428.00 RM 1248.00 Warranty (full warranty) 10 years 1 year 1 year Operation Cost / year RM 170.25 RM 1,109.67 RM 1,109.67 Operation Cost (10 years) RM 1702.50 RM 11,096.70 RM 11,096.70 Total Cost (initial cost + operation cost) for 10 years without maintenance cost RM 7,392.50 RM 12,374.70 RM 12,194.70 Environment Impact free CO2 CO2 Table 2. 1 Comparison between Solar Water Heater and Electric Water Heater * Description is given by Solartech Sales Service Sdn Bhd ** Description is given by Pansasonic Malaysia Sdn Bhd The table above shows the comparison between Solar Water Heater and Electric Water Heater.

It should be done before August 01, 2009, but in stead it was done on August 22, 2009. The reason for the delay because of Introduction is revised proposal, so I decided to postpone it until the same with the date of completion for literature review. For Literature Review, I started it a week earlier than the proposed work schedule due to I need longer time to search information from TARC library and internet. Besides that, I also needed to get the quotation from supplier so that I started my literature review earlier. Luckily, everything in progress and I finished my literature review on time. My supervisor, Mr. Teh Bin Sin checked my works on August 20, 2009 and I printed out all the chapters for interim submission. Report on Changes Involved Date (Week) Issue of Changes Issue of Amendment July 05, 2009 – July 11,2009 Project Title ‘A Comparison between Solar Water Heating System and Electric Water Heater’ changed to ‘A Study into Solar Water Heating System in Malaysian Homes’ The project title changed because ‘A Study into Solar Water Heating System in Malaysian Homes’ is more specific and to fulfill requirement of supervisor. July 26, 2009 – August 01, 2009 Objectives ‘To compare the initial cost, price, durability, maintenance cost and environment impact for solar water heating system and electric water heater’ changed to ‘To compare the initial cost, price, durability, and environment impact for solar water heating system and electric water heater’ Due to the comment from supplier, which is maintenance cost is difficult to calculate or estimate for the following 10 years for water heater, so I decided to take out the comparison of maintenance cost in objective.

Neal Stephensons Snow Crash Essay -- Neal Stephenson Snow Crash Essay

Neal Stephenson's Snow Crash In Snow Crash, a novel by Neal Stephenson, Stephenson examines how expanding technology affects a society. He introduces us to a world where a computer virus is altering people's minds, and where they have no control over themselves. He vividly describes how Hiro, the protagonist, must fight the virus to save the future of the world.   Ã‚  Ã‚  Ã‚  Ã‚  Technology is expanding everyday. Our society has grown and expanded and has become extremely powerful because of new technologies. People are learning how to use computers in place of their tasks. The Internet is a prime example is of expanding technology. One can obtain yesterday's and today's news, listen to music, talk to a friend over seas, view pornography, and countless other things in the privacy of one's home via the Internet. There is no way to really regulate what is on the Internet. Essentially, the government has no place on the Internet. This world is free of from laws. As society moves closer to advanced technology, the government becomes removed. There is no way for them to regulate society's actions once everything is computer based. In Snow Crash, Stephenson creates the Metaverse. In this society no laws exist.   Ã‚  Ã‚  Ã‚  Ã‚  Hiro, the Protagonist, is the narrator of the novel. As Hiro tells the story, there is no form of government anymore. The government has long been over, and has been replaced by individual corporations with their own sets of rules. There were many corporations, Mr. Lee's Greater Hong Kong being one of them, where one could be a citizen and apply for a passport. Mr. Lee owned franchises in Hong Kong and people needed a passport in order to get into Greater Hong Kong (p.99). Information was vital to these corporations. Mr. Lee's Greater Hong Kong asked people to share information with them if the person decided to join the corporation and become partners (p.99). Hiro worked for the CIC (Central Intelligence Agency), where he got interesting information-gossip, videotape, audiotape, or a computer disc concerning different corporations. Large corporations, or any person interested in something he found, paid him for use of the information and used it to their advantag e (p.22).   Ã‚  Ã‚  Ã‚  Ã‚  As well as working for he CIC, Hiro is a freelance hacker. He is one of the creators of the Metaverse. The Metaverse is "virtual reality." People here are represented by a pie... ... the Internet, you can have an e-mail address which can essentially take the place of regular mail as well as the telephone. With all the technology today, the Internet is still off-limits to certain people. Everyone does not own a computer and because of this, everyone is not computer literate. Mostly middle and upper class people have their own laptops, or computers, and are able to pay for Internet service. Other people, like student's who use their schools computers or people who go to libraries, are forced to use whatever equipment is available, which is, in most cases, not top of the line and sometimes may or may not have the Internet. Soon this world will be computer-based and if you do not have your own computer or at least access to one, you will be behind. The Internet is an important part of computers considering the many uses it offers. Stephenson foretells how the future for today could be if we allow all these new technologies to take over our lives. Everyone must learn how to incorporate new technology into their lives without letting it consume them, even though it will still consume many. Once it consumes you , you are pretty much a victim of Snow Crash.

Robert Frost Essay -- Robert Frost Poet Poems Essays

Robert Frost   Ã‚  Ã‚  Ã‚  Ã‚  Robert Frost, an Americian poet of the late 19th century, used nature in many of his writings. This paper will discuss the thought process of Frost during his writings, the many tools which he used, and provide two examples of his works.   Ã‚  Ã‚  Ã‚  Ã‚  Robert Frost was born in San Franciso on March 26, 1874, but later moved to Lawrence, Massachuschusetts (after his father died) where he did most of his writing. He was a simple man who taught, worked in a mill, was a reporter, was a New England farmer, and wrote. Throughout his life he had always been interested in literature. He attended Dartmouth College, but remained less than one semester. In 1894 he sold his first work â€Å"My Butterfly: An Elegy† to a New York journal. A year later he married Elinor White. From 1897 to 1899 he attended Harvard College as a special student but left before he acquired his degree. For the next ten years he wrote poems, operated a farm in Derry, New Hampshire, and taught at Derry’s Pinkerton Academy.   Ã‚  Ã‚  Ã‚  Ã‚  In 1912 he sold his farm and moved to England where he could work on his writings full time. He was an instant success! â€Å"A Boy’s Will† was accepted by a London Publisher and a year later so was â€Å"North of Boston†. He also began to get recognized in America.   Ã‚  Ã‚  Ã‚  Ã‚  The Frosts sailed for America in 1915 and landed in New York two days after the Americian release of †North of Boston†. The book was a good success and he used the profits to buy a farm in Fanconia, New Hampshire. During this time Frost began to write his most successful poems.   Ã‚  Ã‚  Ã‚  Ã‚  Frost was once asked his thought process during writing; he responded:   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"I sometimes speak from the last thing that happened to me. I got asked today if I think up poems. Do I think them up? How do I get the right one? Well, it is the hardest thing in the world to tell. But I don’t think up poems. I pick up a lot of things I thought of to make a poem; that is a lot of scattered thoughts through the days that are handy for the poem-that’s about all. That’s where the thinking comes in.†   Ã‚  Ã‚  Ã‚  Ã‚  That is truly an amazing feat; he would just walk around looking at things and a poem would come into his head. He would write these entire inspirational poems in his head and didn’t even think that it was unusual. The best poet of the 20th century did not write rough drafts!   Ã‚  Ã‚  Ã‚  Ã‚  In 1915 he moved to New England and... ... the inauguration of President John F. Kennedy. He once stated that his major goal in life was to write â€Å"a few poems that would be hard to get rid of.† Well, congratulations Mr. Frost. Works Cited Field, Evgene. Poems of Childhood.

Brief Summary of Daniel Willingham †Why Don’t Student Like School Essay

The answer to the question ‘why don’t students like school’ was explained very clearly on the first chapter. It was made clear that our brains are slow and unrealiable. Our brains tend to avoid thinking, which makes it unlikely for us to like thinking. But apparently our brains release some amount of dopamine when there are cases of ‘successful thinking’. So the trick is to give students problems that are challenging but also solvable. There are 3 types of memory stated in the book; the ‘environment’ memory, working memory and also long-term memory. For us to remember things better, we can trick our working memory with techniques such as ‘chunking’ since things can only get to the long-term memory through working memory. Emotion and interest also play a part in the remembering process. Things that grab our interest would trigger our mind to think, and memory is believed as the residue of thought while emotional events will be better remembered–unrelated to repetition–such as weddings, 9/11 tragedy or birthday parties. Sometimes we go on ‘auto-pilot’ on stuff that we regularly do, this is caused by repetition or practice, it can help us focus on other important things while still doing our regular activities such as chewing food, driving, reading and etc. The working memory has a very limited capacity, our brain can’t take too much information, if we do, it could lose track of what we’re doing and thinking fails. As an example, that’s what actually happened to me when I was reading the book, the first chapters really crowded my brain and it was actually hurting. Putting the material in a story form can also help students remember because stories are easy to comprehend, interesting and somehow easy to remember. Background knowledge is crucial during learning process as it helps new information to stay in our memory as it was stated that ‘Understanding new ideas is mostly a matter of getting the right old ideas into working memory and then rearranging them–making comparisons we hadn’t made before’ (Willingham, 2009). As I get to the 4th chapter, reading the book was much more easier to understand as I already have the background knowledge. The author explained how important it is to practi ce or drilling. The bad image of how practice is tiring and hard has made students often avoid practicing. However, it is not necessary to learn for a few hours in a row, in fact, doing so with ‘space’ will make  learning more effective, I believe this method wouldn’t feel so tiring and hard. In the 6th chapter, Willingham explained how experts have extensive organized experience, which makes them think in deep structure. Experts work on their subject for several hours a day, to get students to think like experts, learning should be done for several hours. There is a perception that experts would solve puzzles faster, however experts often take more time to think as they dig into more depth than novices. I personally agree with all the content in the book. I think the book basically covered all the aspects that could help students learn cognitive subjects efficiently. Proving Willingham’s theory on background knowledge and remembering, I read the book while relating to y our teachings and found that the content of the book was much easier to understand since some of them were also taught in your lessons. I guess you’re the living proof that the book is effective. I can see clearly how the writer actually performs his theory on chapter on through the book such as how he chose a question instead of a statement for the book’s title to grab attention. Often repetitions of definitions come up in different chapters of the book, which I believe is to help readers remember things. Some theories that are in the book are actually from our daily life that I haven’t noticed before. Stories have been used to help me learn, unconsciously, by teachers before but I did not really acknowledge how using stories for effective learning is actually a thing. The same with the emotional and interest theory on forgetting. What I did not expect was how we actually get satisfaction from learning, my perception towards learning has always been about something that is tiring and that it is important but wouldn’t give you any pleasure. Although I would add some things that might have been left behind by Willingham from his point of view. I would deli berate over a few things from a student’s perspective. It’s the ‘whom’ that I think he might’ve left out. Teachers aren’t all the same and each has their different styles of teaching. One teacher might have been basing his teaching on your book but the other doesn’t. I think this might affect how the students study at home. The materials–such as books or presentation slides–might just be insufficient or students might have got used to the ‘Willingham style’, students might not be able to keep up with the other subjects. If Willingham would add another chapter on changing student’s learning style permanently or something. That would be perfect. He  actually did mention how to treat the students in chapter 8 but I don’t think showing that the teacher has confidence in the student would change how the student thinks permanently. Another thing is just a method that I often use in memorizing process. I try to ‘act’ the theory in order for me to remember the matter. This is just an additional method that I think could have a space in the book. After reading the book, I realized that having read the book had somehow changed my perspective about some few things such as practice can be done in a more effective–less tiring–way, how to grab atte ntion–in case I have to teach–and few other things. Well, I guess that is all. I really think this is an outstanding book by how I actually enjoyed reading it. I really hope that teachers would use this book as their basis. But afterall a student’s performance does not only depend on the teachers but also the student. I think the book itself is applicable for students with some change of perspective and behavior.

American History X vs. Malcolm X

The movies American History X and Malcolm X both tackle critical social issues evident in the past as well as in the present. These issues revolve around race and culture, which is well related to issues like freedom, individuality, discrimination, and social acceptance. In both the films, these issues were not really highlighted at the very beginning. Both Malcolm X and American History X showed a socially negative start, like the involvement of Edward Norton in a White supremacist group, or Denzel Washington’s portrayal of Malcolm X’s criminal past.But despite this, the film rebounded on the positive light through the realizations of the main characters at some points in the film. These realizations or moments of truth were life changing experiences for Edward Norton and Denzel Washington, as they portray the turning points in the life of the characters that they play in their respective movies. In American History X, Edward Norton’s moments of truth occurred t o him when he was sent to prison, after murdering a black man who tried to rob him. At first, the murder wasn’t really a big deal to him, since his principles dictate that it was the right thing to do.As a white supremacist, he sees himself as a better person than the person he killed, and that his deed was that of good will. He was even grinning when he was arrested (Kaye). When he was sent to prison, he realized that life was not only black and white. He was able to see the wrongs of what he thought was right, and because of that, he slowly distanced himself from the brotherhood and the beliefs that he catered for a long time. He began associating with people from other races, though it was hard for him, as he had to suffer the harsh ways of the people he turned away from.Despite all these, he became a changed man, and eventually desired to live a better life with his brother. On the other hand, Denzel Washington had his moments of truth in the film Malcolm X, in the same m anner as that of Norton in American History X. During his youth, Denzel Washington lived a life of crime in the streets. He was a member of gangs which had dealings with illegal activities. He was arrested for robbery at one time, and was then sent to prison (Lee). It was the life in prison that changed him personally.He met a man who introduced him to the Nation of Islam, and also motivated him to move away from a life of vices and crime. He stopped drinking and smoking, and eventually succumb to the Islamic ways that was introduced to him. After prison, he continued to live a clean life, and opted to influence others of his newfound strength. He also realized that race should not be an issue in society. Both the films realized the truth through their experiences. It was not only based on the words or the influences of others, but also on the accompanying actions that they experienced.The lives they lived previously were not good at all, but it served as a comparison for them when they decided to live away from hatred and discrimination (Cyrus and Fiske-Rusciano). It was their experiences and acquaintances in prison that made them realize the truth about their lives. They shunned away discrimination, dominance, and hatred, and embraced a life of acceptance and freedom, despite the dire consequences that they faced at the end of the movie. The truth that they found proved to be very ironic in the end of the films.In American History X, Norton’s brother was shot dead by a black gang member. On the other hand, Malcolm X was assassinated before giving a speech for the masses. Despite these, the truth that they found was not at all fragile. If they decide to revert back to their old selves and exact revenge on those who did them wrong, the cycle of hatred would just continue. Norton realized this in a hard hitting manner. He had killed somebody before, now it is returned to him when his brother was killed. Malcolm X led a criminal life in his youth, and in the end, he was assassinated.The truth that they found was cemented by these events. There is a need for a social acceptance in order to stop the cycle of hatred and violence. This is the truth. Edward Norton and Denzel Washington learned this truth the hard way.
