American Government In Contrast To Lao-Tzu And Machiavelli Essays

American Government In Contrast To Lao-Tzu And Machiavelli Peter Ryan Welch 382-92-3692 February 6, 2001 Dr. Allegra Blake, ENG 201 American Government in Contrast to Lao-Tzu and Machiavelli In comparing and contrasting the governmental philosophies of the great thinkers Lao-Tzu and Machiavelli, I have found a pleasant mix of both of their ideas would be the best for America today. Lao-Tzus laisse-faire attitude towards the economy, as well as his small scale military is appealing to my liberal side, while Machiavellis attitude towards miserliness which causes low taxes appeals to the right wing. These great thinkers contradict the popular saying all great thinkers think alike. They have several ideas, such as taxes, that are the same, while other ideas, like the involvement of government in citizens' everyday lives are totally opposite. I shall start with the ideas of Machiavelli, then move on to Lao-Tzus, and finally a comparison and application into American life. Niccolo Machiavelli believes in a strong government. The leader should be strong and feared. I believe he gets this idea from the fear of God; no one is supposed to question God because he is so feared, and in the same sense, no one should question a strong leader. Machiavelli realizes that the leader should be feared, but not hated. A hated leader will probably be killed in a rebellion. One also can not be loved. Any compassion towards your citizens will make them believe you are weak, and they will rebel. He thinks a very strong military is necessary at all times, and that powerful arms should be available and in hand. This idea is similar to that of right wing America and our friends, the National Rifle Association, who believe assault rifles are Americas pastime. The nation should always be prepared for war, and should always be searching for new lands to conquer. This is much like our cold war with the USSR and the new lands to conquer would be anything Communist. These wars sho uld go on without high taxes. High taxes as well cause rebellion. Case in point: the high taxes levied against America by the British, as well as other strong factors, led to the American revolution. He believes a government should be miserly with its own goods. That is not to say you cant steal the goods of conquered countries and be liberal with them. Try not to be too generous, however. A quote I once read says remember to pillage before you burn. This reminds me a lot of the ideas of Machiavelli. According to him, one should say one thing just to make the people happy, and do another. He believes one should only keep his word if it is for the benefit of the nation. Six words: read my lips, no new taxes, come to mind. George H.W. Bush said these words, but acted differently. Machiavellian? Maybe. Bush shortly after had the largest tax hike in the nation's history to try to save us from the worst recession since the Great Depression. I believe this is the sort of thing Machiavelli is talking about. Do whatever you can to keep the people happy, but when it comes down to it, what makes them happy may not be best for the state as a whole. He believes that people are generally bad and greedy, so they will take whatever you give them. Lao-Tzu is not exactly polar opposite of Machiavelli, although he is close. He believes that man in a state of nature is generally good and not greedy. What makes man greedy is overemphasis on material objects, and if you let a man go free in nature, he will be good. Lao-Tzu believes in a state of peace; war is not necessary. Lao-Tzu thinks decent men detest weapons. Weapons are only needed when entirely necessary, in a state of defense. This is sort of a liberal point of view of war. He states violence, even well intentioned, always rebounds upon itself, therefore, any attack upon another country will result in an attack upon yourself. As far as the scale of government, he is rather conservative and would side with the American Republican party, believing a smaller, more unnoticed government is better. When the Master

Intersubjectivity

Intersubjectivity (Kahneman Tversky, 1979). Taking Israel as a case study, through media coverage of these indicators, to public opinion, and finally, individuals voting intentions and aggregate voting behavior, the last two are rather new in agenda-setting and priming research, especially in research concentrating on political parties that is conducted in a natural setting. Analyses of four national election campaigns are included (1996, 1999, 2001, and 2003). This was a dramatic period, in which, among many other events, a prime minister was assassinated, the peace process with the Palestinians fell, the second Intifada, the Palestinian uprising, erupted and the national economy was tottering on the verge of collapsing. Although they rely heavily on the media, most Israelis have direct experience with the worsening security and economic real-world conditions. For example, almost 4,000 Israeli civilians and soldiers (out of about 6.6 million Israelis) were killed or injured in numerous terrorist at tacks within Israel and in fighting against the Palestinians in the year preceding the 2003 election. The media, alternatively, may get involved only casually and discontinuously in public affairs and even remain ill-mannered on the details. Those who have already made up their minds, the effects are destabilized. News media does not have the prowess to invent or cover up problems, but only modify the alertness, priorities and salience people fix to a set of problems. Not enough research has been done. Incomplete and inconclusive research in establishing an underlying connection between public salience and media coverage is lacking. Inadequate research in the dominion of modern forms of news media like social websites has not been fully integrated in the models to perceive the magnitude of influence it has on people. What is apparently detectable is that, "In an effort to survive, traditional newsrooms have embraced newsroom blogs as an alternative vehicle for news delivery."(Hamm, 1998). Until now, there is continuity in social-economic and this is between the users of modern forms of news media and those who dont. In summation, there are resemblances and interconnections between agenda setting, priming, and framing, but they are not matching approaches. Framing studies have, by a large magnitude outdone both agenda setting and priming studies in reputation throughout the past decade; although framing has not been properly conceptualized and defined like the other two seem to be.

Buy to Let Investment Market Assignment Example | Topics and Well Written Essays - 1500 words

Buy to Let Investment Market - Assignment Example This paper will focus on four areas of the buy to let marketplace: explanation of the taxes a property investor will be subjected to, how the property investor can minimize their capital gains tax liability through careful tax planning, how to be careful not to attract an investigation by the Inland Revenue, and, the tax benefits of setting up a property company to save property tax. There are a variety of taxes that the investor will be required to consider when investing in buy to let properties including: stamp duty and inheritance tax. There are some taxes that can be reclaimed against the tax on rents for buy to let properties such as "costs of maintenance, such as insurance, cleaning, gardening, agent's commission and other reasonable management expenses (but not home improvements) and a wear and tear allowance of 10% of the rents received may be deductible." (Alan Harvey, 2006) liable when, land or residential property is purchased where where the purchase price is above 60,000, or where it is transferred and the outstanding mortgage amount is greater than 60,000. The rates of stamp duty vary between 1% for properties less than 250,000 and 4% for properties over 500,000. It is also worth noting that there are certain areas that are exempt from stamp duty, where the property is purchased for less than 150,000. (Weller and McTernan, 2006) if at the timeThe other tax that the investor will be responsible is inheritance tax which is commonly referred to as the 'gift' or 'death tax'. Weller and McTernan (2006) explain the inheritance tax: if at the time of your death you pass on part or the whole of your estate then again the inheritor could be liable to pay Inheritance Tax. There is currently an IHT threshold level of 263,000 for the 2004-2005 tax year. Anything above this amount is taxed at 40% i.e. at the highest rate. This means that if at the time of death, your whole estate is valued at less than 263,000 then the inheritor will have no tax to pay. (Weller and McTernan, 2006) The two things you can't escape are death and taxes, but, why not make an investment work for the investor. By buying into the buy to let scheme, an investor's main goal is to gain equity buy minimising what they will pay to the Inland Revenue department. The investor's objective is to minimise their capital gains tax liability through careful tax planning. Minimising Capital Gains Tax Capital gains tax is payable "if a property is sold for a higher price that what was paid for it, or when a property or part of a property is transferred to someone who is not your spouse." (Weller and McTernan, 2006). Thus "the capital gain is calculated by deducting the allowable costs and Inland Revenue tax relief's, from the selling price of the property. Examples of allowable costs include, property extensions, purchasing related costs etc." (Weller and McTernan, 2006). As some investors fail to realise that when they sell their property, they could end up paying an extremely large tax bill of anywhere up to 40% of the net profit of the sale of the property.

Hajj The Pilgrimage to Makkah Essay Example | Topics and Well Written Essays - 500 words

Hajj The Pilgrimage to Makkah - Essay Example When people from all around the world stand in silence and in a row while praying in the mosque, it shows the exhibition of equality and discipline among the Muslims. Hajj is an annual congregation of worship. 2. Lesser pilgrimage is known as the Umra and is commonly referred to as Haj-e-Asghar. Although many acts of worship performed in Umra are those performed in of Hajj, there are certain fundamental differences as Hajj is obligatory, Umra is not. Hajj can only be performed on prescribed dates, but there isn't any time and date fixed for performing Umra. It is undesirable to perform Umra between 9th and 13th of ZilHajj of the Islamic calendar. Umra can be performed individually (while Hajj is performed in groups) and is a shorter course of pilgrimage. 3. Ihram: Pilgrims put on Ihram during the Hajj ritual. They are 2 white sheets of unsown cloth. One sheet is used for covering the lower portion of the body (from the navel downwards) and the other is used for covering the upper portions of the body. Head while remaining uncovered. Ihram for women is their everyday clothes. It is compulsory for women to cover their heads, but no cloth should touch their faces. Before putting on the Ihram the pilgrim should first take a full bath and clean his body thoroughly. He may then put on Ihram and cover his head with some unsown piece of cloth and offer prayers. Ihram is the first and foremost obligation of Hajj.

Compare and contrast leadership and management styles. How does your Essay

Compare and contrast leadership and management styles. How does your answer help create an ethical environment - Essay Example As a function of such a definition, the reader can and should understand the management style as more of a nuts and bolts approach that tends to be somewhat formulaic and rigid whereas leadership engenders the unique ability to mold and integrate with changes as a means of seeking the best path. It is further important to understand that such a level of approach does not specify one or the other must be engaged upon. As such, it is possible and desirable for an individual to accomplish both of these styles of oversight in order to be an effective vehicle for change within a given institution. Although not all individuals can fulfill the requirements of each of these categories, the individual that does is able to see from both perspectives and seek to direct the firm/group/ or entity in the most appropriate way. With regards to ethics, the leadership and management styles play an integral role in determining the priorities of the given individual. One could even argue that ethics violations only spring from management styles if and when the management style is engrained within the company’s culture. This is due to the fact that management styles are almost always formulaic and required attributes that the individual most ascribe to in order to meet the standards of the organization or group he/she is representing to the employees. Conversely, leadership styles fall prey much more easily to ethical violations due to the fact that these are almost always more innately tied to the ability of the individual to incorporate what they heave learned from past experience, as well as their own personality into the change mechanism they are attempting to integrate with. In order to create an ethical environment, it is incumbent upon the culture and oversight mechanisms of the firm to seek to in still a strong level of ethics into the management styles that they engender with the leadership. In such a way, ethical decision making and

The Role of Youth Work in Modern Ireland

The Role of Youth Work in Modern Ireland Introduction The focus of this essay is the role of youth work in modern Ireland, in addition, to providing examples from practice. Youth work can generally be defined as teaching young people in an informal context as it usually occurs out of school and consists of various activities that aim to provide new opportunities for ‘young peoples social development’( Hurley Treacy, 1993). In Ireland, youth work has been regulated and State involvement has been visible under legislations such as Youth Work Act 2001 and the National Youth Work Development Plan 2003-2007 (Burgess Herrman, 2010). Within youth work an individual can volunteer to help young people or can be a paid worker within the field. Throughout history Irish youth work has relied enormously on ‘voluntary effort’ both individual and institutional (Devlin, 2012). This will discuss the role of a volunteer, a paid youth worker, as well as comparing both of these roles. Volunteerism The goal of volunteering is to help individuals, groups, organization, cause, or a community, without expecting any material rewards (Musick Wilson, 2007). Within the realm of youth work the service providers can either be paid or volunteer their time. However, there is much more to a community other than its geographic location, the community, is a ‘social and psychological entity that represents a place, its people, and their interaction’ (Luloff Bridger, 2003; Wilkinson, 1991 cited in Brennan (2007). The majority of youth work in Ireland is voluntary, therefore, the voluntary action and social participation can be viewed as the key to the development of the community (Devlin, 2010) in Ireland volunteerism has been consistent with the youth work policy. Three major factors that contribute to volunteerism is that the service is not compulsory, not paid, and non-statutory (Devlin, 2010). Voluntary youth work organisations are non-statutory an example of this can be seen in youth work organisations that have ‘voluntary management committee’ in comparison to paid ones that are appointed in other organizations (Doran, 2014a). Young people are not required to go to a youth work organization as it is not compulsory which is markedly different from their relationship with the formal education system (Devlin, 2010). There are different types of volunteering such as formal volunteering this consists of a volunteer having direct contact with young people of the service, this is much more directly linked to affluent areas wherein the voluntary youth services, have more volunteers in comparison to paid professionals. According to Doran (2014a), there is an average of ‘50 volunteers to 1 paid professional worker in voluntary services and 6 volunteers to 1 paid professional worker in community youth work projects’ (Doran, 2014a). Whilst there are formal volunteerism there is also informal this usually occurs in disadvantaged areas, and can more often occur when family or friends try to help out a parent or young person. Volunteers also help make aware of issues that are occurring within the community and encourage ‘outreach programs that partner with ongoing voluntary activities’ (Brennan, 2007). Thus, creating a greater result by coordinating efforts between group and may result in meeting young people’s needs. Moreover, volunteering can also create a positive and friendly atmosphere for children as it allows different individuals with an array of skills to feature their many talents and abilities to the youth work setting (Doran, 2014a). Through voluntary efforts young people and volunteers are able to interact with one another and ‘begin to mutually understand common needs’ (Luloff Swanson, 1995 cited in Brennan (2007). Further, this interaction should improve the social, cultural, and psychological needs of younger individuals (Brennan, 2007). Volunteers can also take part in activities within the community such as helping to coach kids sports, field trips, art classes, and mentoring, all of these activities should enhance a young person’s social development. The role of a Youth Worker Youth work in Ireland has become increasingly ‘professionalised over the last decade and has a greater sense of established identity’ (Jenkinson, 2013). Youth work that predominately correlates with paid youth work occurs mainly in disadvantages areas. Furthermore, within disadvantaged areas youth workers participate in a programme known as detached youth work. These programmes allow youth workers to go out and find young people either on the street or youth centres. Youth workers are able to meet young people and grow to develop relationships (Nuffield Foundation, 2008). This service is provided based on mutual trust and developing respect on the young person’s terms e.g. going to a local area at night where young people tend to be. The youth worker will be able to talk to the individuals and assess their needs as the relationship develops workers will be able to reach young people in a comfortable setting. The goal of detached youth work is to build effective re lationships and gain trust. Youth workers act as role models for young people and relationships created supports the personal learning and development of young people (Doran, 2014b).Youth workers now have to work towards an established ‘youth work curriculum’ this is a targeted specified participation rates and evidence of young people’s progression towards and achievement (Nuffield Foundation, 2008). Young people are generally portrayed as a group that are personally or socially lacking in terms ‘of education, morality or even the civilising effects that can only be accessed with the aid youth development worker’ in predominantly disadvantaged area (Belton, 2012). Youth workers have to work with an increasing policy that ‘emphasises targeted, intensive interventions, shaped by a ‘deficit’ model of youth’ (Lee, 2010) The Deficit Model of youth work, reflects a negative perception of young people it is in intended for individuals that are unable to take care of themselves (Lee, 2010). This model presumes that young people are difficult to understand, rebellious, misbehaved and have numerous shortcomings and weaknesses. However, the role of a youth worker should reject the deficit model, and promote a model that emphasises young people as optimistic. Volunteerism and Youth Workers Roles Volunteers and youth workers both work to help and support the community and the welfare of young people. However, while both are working towards a common goal, both fulfill different roles. A youth worker is in charge of doing an array of tasks to assist the youth such delivering programmes and assessing the needs of young people, working within community projects, monitoring and reviewing the quality of the local youth work provision, working with partnerships with professionals from other organisations that support young people such as ‘health, police, education, youth offending teams and local authorities’ (Prospects, n.d.) and drawing up business plans and making formal presentations to funding bodies. These are all significant to continue getting funded so that youth programmes are not ceased, thus, youth workers can continue to provide for young people within the area (Prospects, n.d.). In contrast, volunteers are unpaid and working freely on their own time. Volun teers work primarily face-to-face with the youth and help to provide a safe environment for young people as well as contributing to specific skills that may help young people e.g. social skills. Further, to encourage young people to be socially active and participate within their community. Both of these roles are different yet everyone is working towards helping young people. Conclusion Overall, the main objective of this essay was to describe the role of volunteers and youth workers within modern Ireland. Whilst this essay gave a clear understanding of both volunteers and youth workers it also gave an account of their roles within youth work and their similarities and differences. Thus, concluding that while both roles are different both of these groups are a valuable part of the community and in young people lives. References Belton, B.

The Fall Of The Roman Empire :: essays research papers fc

The Fall of the Roman Empire For men who had easily endured hardship, danger and difficult uncertainty, leisure and riches, though in some ways desirable, proved burdensome and a source of grief. The causes for the breakdown of the early Roman Republic cannot be attributed to a single event, trend or individual, rather it was due to a combination of all three in varying degrees. The principal and fundamental cause was the breakdown of the political checks and balances, particularly the Cursus Honorum from 133 BC onwards. This subversion occurred both accidentally and through the subversive behavior of individuals, unconsciously and consciously undermining the fabric of the republic in their quest for power and glory. One substantial outcome of this incapacitation was the emergence of violence as a political means. Once this had occurred the end of the old republic was heralded an autocratic dictatorship was born. The republic was born out of a collapsed monarchy and was specifically geared to prevent a centraliz ation of power. The mechanisms to this end were contained in the Cursus Honorum, a document that outlined the ladder of offices. It demanded, among other things, 10 years of military or legal service before any magistracy could be held, annual election and two years between consecutive offices. This system was designed to ensure that no individual could become too powerful by dividing jurisdiction between several groups and allowing for veto. The Gracchi brothers, Tiberius and Gaius are often blamed for causing divisions and antagonizing the aristocracy and particularly the senate by introducing laws and legislation that, although promoting egalitarianism for the poor, were catalysts to later breaches of the Cursus Honorum. Both Tiberius and Gaius had laws enacted without consulting the senate. This weakened the senate's power and started a trend of ignoring the senate that remained until the breakdown. These Graccian reforms included the implementation of a welfare system whereby R omans citizens would be given free corn and the Lex Agraria or land reforms that broke down the latafundia and increased the number of small-scale farms. The welfare corn system not only aroused violent anger from the nobility but also created an urban mob that relied on handouts and later participated in violence. Tiberius Gracchus ran for election to the tribunate for two years consecutively (123 and 122 BC). This was in direct contradiction to the Cursus Honorum. The senate, when they heard of Tiberius' plan, killed him.

Explanation of Modern Physics

Explanation of Modern Physics While the term â€Å"modern physics† often suggests that all that came before it was incorrect, 20th and 21st century additions to physics simply modified and expanded the phenomena which Newton and his fellow scientists had already contrived. From the mid-1800’s onward, new advances were made in the way of physics, specifically the revolutions of Einstein’s relativity, removing mankind further from the absolute, and quantum mechanics, which replaced certainty with probability. All of this led to an advance in nuclear weaponry, the advancement of laser technology, and the information age of computers.Although it directly contradicted the classical equipartition theorem of energy, black body radiation was one of the first discoveries in modern quantum mechanics. This theorem states that within thermal equilibrium, where each part of the system is the same temperature, each degree of freedom has 12kBT, kB representing the Boltzmann con stant, of thermal energy associated with it, meaning that the average kinetic energy in the translational movement of an object should be equal to the kinetic energy of its rotational motion.By this point, it was known how heat caused the atoms in solids to vibrate and that atoms were patterns of electrical charges, but it was unknown how these solids radiated the energy that they in turn created. Hertz and other scientists experimented with electromagnetic waves, and found that Maxwell’s previous conjectures that electromagnetic disturbances should propagate through space at the speed of light had been correct. This led to the explanation of light itself as an electromagnetic wave.From this observation, it was assumed that as a body was heated, the atoms would vibrate and create charge oscillations, which would then radiate the light and the additional heat that could be observed. From this, the idea of a â€Å"black body† formed, an object that would absorb all radia tion that came in contact with it, but which also was the perfect emitter. The ideal black body was a heated oven with a small hole, which would release the radiation from inside.Based on the equipartition theorem, such an oven at thermal equilibrium would have an infinite amount of energy, and the radiation through the hole would show that of all frequencies at once. However, when the experiment was actually performed, this is not the result that occurred. As the oven heated, different frequencies of radiation were detected from the hole, one at a time, starting with infrared radiation, followed by red, then yellow light, and so on.This proved that high oscillators are not excited at low temperatures, and that equipartition was not accurate. This discovery led to Stefan’s Law, which said that the total energy per square unit of black body per unit time, the power, is proportional to the absolute temperature to the fourth power. It also led to Wien’s Displacement Law, stating that the wavelength distributions of thermal radiation of a black body at all temperatures have essentially the same shape, except that the graphs are displaced from each other.Later on, Planck characterized the light coming from a black body and derived an equation to predict the radiation at certain temperatures, as shown by the diagram below. For each given temperature, the peaks changed position, solidifying the idea that different temperatures excite different levels of the light spectrum. This was all under the assumption that radiation was released in quanta, now known as photons. All of these laws help modern physicists interpret radiation and make accurate estimations at the temperature of planets based on the radiation that comes from them.Einstein used the same quantization of electromagnetic radiation to show the photoelectric effect, which disproved the idea that more intense light would increase the kinetic energy of the electrons radiated from an object. Photo electric effect was originally the work of Heinrich Hertz, but was later taken on by Albert Einstein. Einstein determined that light was made up of packets of energy known as photons, which have no mass, but have momentum and energy given by the equation E=hf, h representing Planck’s constant and f representing the frequency of the light used.Photoelectric effect explains that if light is shone on a metal with high enough energy, electrons will be released from the metal. Due to the energy equation, light of certain low frequencies will not cause the emission of electrons, not matter how intense, while light of certain high frequencies will always emit electrons, even at a very low intensity. The amount of energy needed to release electrons from a metal plate is dependent upon the type of metal it is, and changes from case to case, as every type of metal has a certain work function, or an amount of energy needed to remove an electron from its surface.If the photons that hit t he metal plate have enough energy as the work function of the metal, the energy from the photon can transfer to an electron, which allows it to escape from the surface of the metal. Of course, the energy of the photon is dependent upon the frequency of the light. Einstein postulated that the kinetic energy of the electron once it has been freed from the surface can be written as E=hf-W, W being the work function of the material. Prior to Einstein’s work in photoelectric effect, Hertz discovered, mostly by accident, that ultraviolet light would knock electrons off of metal surfaces.However, according to the classical wave theory of light, intensity of light changed the amplitude, thus more intense light would make the kinetic energy of the electrons higher as they were emitted from the surface. His experiment showed that this was not the case, and that frequency affected the kinetic energy, while intensity determined the number of electrons that were released. By explaining th e photoelectric effect, scientists find that light is a particle, but it also acts as a wave. This help support particle-wave duality.In order to explain the behavior of light, you must consider its particle like qualities as well as its wave like qualities. This means that light exhibits particle-wave duality, as it can act as a wave and a particle. In fact, everything exhibits this kind of behavior, but it is most prominent in very small objects, such as electrons. Particle-wave duality is attributed to Louis de Broglie in about 1923. He argued that since light could display wave and particle like properties, matter could as well.After centuries of thinking that electrons were solid things with definite positions, de Broglie proved that they had wave like properties by running experiments much like Young’s double slit experiments, and showing the interference patterns that arose. This idea helped scientists realize that the wavelength of an object diminishes proportionally to the momentum of the object. Around the same time that de Broglie was explaining particle-wave duality, Arthur Compton described the Compton effect, or Compton scattering.This was another discovery which showed how light could not solely be looked at as a wave, further supporting de Broglie’s particle-wave duality. Compton scattering is a phenomenon that takes place when a high-energy photon collides with an electron, causing a reduced frequency in the photon, leading to a reduced energy. Compton derived the formula to describe this occurrence to be ? ‘-? =hCme1-cos? = ? c(1-cos? ), where ? ‘ is the resulting wavelength of the photon, ? is the initial wavelength of the photon, ? is the scattering angle between the photon and the electron, and ? c is the wavelength of a resting electron, which is 2. 26 ? 10-12 meters. Compton came about this by considering the conservation of momentum and energy. Although they have no mass, photons have momentum, which is defined by ? =Ec=hfc=h?. In order to conserve momentum, or to collide at all, light must be thought of as a particle in this case, instead of a wave. Quantum mechanics is not the only facet of modern physics, and it shares equal importance with relativity. Relativity is defined as the dependence of various physical phenomena on relative motion of the observer and the observed objects, especially in relation to light, space, time, and gravity.Relativity in modern physics is hugely attributed to the work of Albert Einstein, while classical relativity can be mainly attributed to Galileo Galilei. The quintessential example of Galilean relativity is that of the person on a ship. Once the ship has reached a constant velocity, and continues in a constant direction, if the person is in the hull of the ship and is not looking outside to see any motion, the person cannot feel the ship moving. Galileo’s relativity hypothesis states that any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments.This idea led to the realization that velocity does not exist without a reference point. This idea of a frame of reference became very important to Einstein’s own theories of relativity. Einstein had two theories of relativity, special and general. He published special relativity in 1905, and general relativity in 1916. His Theory of Special Relativity was deceptively simple, as it mostly took Galilean relativity and reapplied it to include Maxwell’s magnetic and electric fields. Special relativity states that the Laws of Physics are the same in all inertial frames.An inertial frame is a frame in which Newton’s law of inertia applies and holds true, so that objects at rest stay at rest unless an outside force is applied, and that objects in motion stay in motion unless acted upon by an outside force. The theory of relativity deals with objects that are approaching the speed o f light, as it turns out that Newton’s laws begin to falter when the velocity gets too high. Special relativity only deals with the motion of objects within inertial frames, and is quite comparable to Galilean relativity, with the addition of a few new discoveries, such as magnetic and electric fields and the speed of light.The theory of general relativity is much more difficult to understand than special relativity due to the fact that it involves objects traveling close to the speed of light within non-inertial frames, or frames that do not meet the requirements given by Newton’s law of inertia. General relativity coincides with special relativity when gravity can be neglected. This involves the curvature of space and time, and the idea that time is not the definite that we have always assumed that it was. General relativity is a theory that describes the behavior of space and time, as well as gravity.In general relativity, space-time becomes curved at the presence o f matter, which means that particles moving with not external forces acting upon them can spiral and travel in a curve, which becomes conflicting with Newton’s laws. In classical physics, gravity is described as a force, and as an apple falls from a tree, gravity attracts it to the center of the Earth. This also explains the orbit of planets. However, in general relativity, a massive object, such as the sun, curves space-time and forces planets to revolve around it in the same way a bead would spiral down a funnel.This idea of general relativity and the curvature of space-time led scientists to realize what black holes were and how they can be possible. This also explains the bending of light around objects. Black holes have massive centers and are hugely dense. Each particle that it includes is also living in space-time however, and so the center must continue to move and become more and more dense from the motion of these particles. Black holes are so dense that they bend s pace-time to an enormous degree, so that there is no escapable route from them.General relativity also explains that the universe must be either contracting or expanding. If all the stars in the universe were at rest compared to one another, gravity would begin to pull them together. General relativity would show that the space as a whole would begin to shrink and the distances between the stars would do the same. The universe could also technically be expanding, however it could never be static. In 1929, Hubble discovered that all of the distant galaxies seemed to be moving away from us, which would support the explanation that our galaxy is expanding.The basis of general relativity is the dynamic movement of space and time, and the fact that these are not static measurements that they have always been assumed to be. However, a key issue is that there has been little success in combining quantum mechanics and Einsteinian relativity, other than in quantum electrodynamics. Quantum el ectrodynamics, QED, is a quantum theory that involves the interaction of charged particles and the electromagnetic field. The scientific community hugely agrees upon QED, and it successfully unites quantum mechanics with relativity.QED mathematically explains the relationships between light and matter, as well as charged particles with one another. In the 1920’s, Paul Dirac laid the foundations of QED by discovering the equation for the spin of electrons, incorporating both quantum mechanics and the theory of special relativity. QED was further developed into the state that it is today in the 1940’s by Richard Feynman. QED rests on the assumption that charged particles interact by absorbing and emitting photons, which transmit electromagnetic forces. Photons cannot be seen or detected in anyway because their existence violates the conservation of energy and momentum.QED relies heavily on the Hamiltonian vector field and the use of differential equations and matrices. F eynman created the Feynman diagram used to depict QED, using a wavy line for photons, a straight line for the electron, and a junction of two straight lines and one wavy line to represent the absorption or emission of a photon, show below. QED helps define the probability of finding an electron at a certain position at a certain time, given its whereabouts at other positions and times. Since the possibilities of where and when the electron can emit or absorb a photon are infinite, this makes this a very difficult procedure.Compton scattering is very prevalent to QED due to its involvement in the scattering of electrons. Modern physics is a simple term used to cover a huge array of different discoveries made over the past two hundred years. While the two main facets of modern physics are quantum mechanics and relativity, there are an amazing number of subtopics and experiments that have brought about rapid change, giving the world new technologies and new capabilities. Thanks to scie ntists like Einstein, Hawking, Feynman, and many others, we have found, and will continue to find, amazing discoveries about our universe.Sources Anderson, Lauren. â€Å"Compton Scattering. †Ã‚  University of Washington Astronomy Department. 12 Nov. 2007.

A Hidden Disease essays

A Hidden Disease essays The daily routine my mother goes through may seem normal to someone who doesn't live with her day in and day out. She gets up in the morning, makes my dad coffee and breakfast and then watches the morning show on ABC. When my dad goes off to work, she begins her routines. My mom starts off jump-roping for an hour, then proceeds to weight-lifting for anorther hour. In the morning she exercises for about three hours. One might say,"Well good for her' I wish I had the time in my life to do that." Or "Wow, she is in really good shape." This would be true, but what they don't know is that my mother has a very serious disease known as Bulimia. To me is is very apparent. I'vew watched her routines for about three years now and it is only scaring me more and more everyday. It has scared me to the extent that I have had repetive nightmares about waking up and finding her dead. I've told my sister about this and she just blocks it out, not wanting to come to grips with what is really wrong with our mom. My mom has always been a very small person. She is 4'11 and most of her life has been about a size 3. She has always been a very attractive woman. The biggest size she ever wore was a 6. She is a confident woman and has always had a relatively high self-esteem. It was not until after her fourth child was born that her Bulimia became evident and apparent. It was and still is a gradual disease. At first, when we would question her not eating, she would tell us that she didn't want lunch because she had been snacking on things throughout the day. Nobody ever saw these snacks thought because my dad works and the kids were always in school, so there was no proof that she was really eating during the day we kind of ignored it. She no longer tells people about snacks, and if you ask her about food before 6pm she will tell you she just isn't hungry. My mom eats dinner. She eats on a smaller plate than everyone else a...

Detonation, Pre-Ignition, and Engine Knocking

Detonation, Pre-Ignition, and Engine Knocking Detonation - generally caused by fuel with a low octane rating - is the tendency for the fuel to pre-ignite or auto-ignite in an engines combustion chamber. This early (before the spark plug fires) ignition of fuel creates a shock wave throughout the cylinder as the burning and expanding fuel-air mixture collides with the piston that is still traveling towards top-dead-center. The resulting knock or ping is the sound of the pistons slamming against the cylinder walls. The effects of detonation may be anywhere from arbitrary to severe. Prolonged and intense knocking can break the piston or the engine, though it is can also endure this slight issue for thousands of miles. Similarly, overheating may cause additional wear-and-tear on the engine, be relatively harmless or cause the engine to catch on fire and break. Common Causes of  Detonation Detonation is most often caused by the use of low-grade engine fuel and its resulting deterioration of your engines parts. However, chamber design plays a key role in determining when and if an engine might detonate unexpectedly. The shape, size, spark location and geometry of the design all help determine where these detonations are likely to occur. An overheated spark plug tip can also cause pre-ignition. This may cause a pinging to occur in your vehicle when driving down a highway, but can actually be sustained in the engine for thousands of miles. If you hear a metallic clicking sound while driving long distances, you should consult your mechanic and see if your  spark plug needs to be replaced. Common Effects Detonation can cause three types of engine failure depending on source and severity: abrasion, mechanical damage and overheating. Mechanical damage happens because the heightened impact of nature can cause parts of the internal combustion engine to fracture. This can especially affect the top or second piston ring land or even the exhaust or intake valves. In  abrasion, the piston head is slowly eroded, creating a microscopic swiss-cheese effect on its surface resulting in less efficiency and eventual breakdown. Overheating, though, is a more serious issue which acts almost like a snowball effect once it starts. Caused by the boundary gas layer getting interrupted against the cylinder head and heat transferring to the coolant via the cylinder head, this overheating of the engine will continue to happen as temperatures increase causing more detonation.   Common Solutions Fortunately, there are a number of solutions to pre-ignition. The best solution is obviously to see your mechanic about the issue, but if you have experience in engine repair, you may also look to the following methods to reduce the chances of engine detonation. Switching to a higher octane fuel in order to reduce the heat of the firing chamber and burn fuel more slowly is the best way to combat false firing. Similarly, reducing engine inlet air temperatures will greatly reduce the chance of pre-ignition and detonation. As a principle, for every 10 degrees cooler the inlet air is, it produces one percent more power. Adjusting engine timing may also help solve this issue. If your engine is firing during throttle at low engine speeds, you may need to adjust the timing two to three degrees.

Computer Communications & Networks Lab Report Example | Topics and Well Written Essays - 1500 words

Computer Communications & Networks - Lab Report Example In order to test connectivity of the Internet connection, ping command is executed from the command prompt of the operating system. The syntax will be ping (space) (destination address), moreover, in order to review hops and delays in accessing the X stream server, the ‘tracert’ command can be executed from the command prompt. The syntax for this command will be tracert (space) (destination address). The ping command utilized Internet Control Message Protocol (ICMP) to check the connectivity of the destination by sending ICMP echo request on periodic basis. Moreover, the ‘tracert’ command demonstrates all the hops and delays that are in the way of that particular destination. Likewise, it is not necessary that only routers are involved in the process of establishing and exchanging information from the required host. The Ethernet is the first device that initiates and constructs a request datagram from the home computer, as it is considered to be the most pop ular Local Area Network technology that is implemented globally (Ethernet. 2007). The connectivity of the Ethernet adapter is established by both wired and wireless networks. However, in terms of wired connectivity, twisted pairs of cable are connected in to the Ethernet RJ45 socket. The other end of the wire is terminated to the router, switch or hub. In this scenario, home user will use a DSL router that will connect the home computer with the Internet Service Provider (ISP). Likewise, the Ethernet construct the datagram consisting of six parameters i.e. destination address, source address, preamble, type, CRC and data. The preamble parameter is responsible for clock synchronization of the data packets from the source and destination. Likewise, the addresses... This report approves that home Internet users do not have DNS configured. ISP is responsible to resolve the URL into IP addresses. In order to do so, the request from the home network will terminate on the ISP Network that will resolve the URL and sends the request to the relevant destination accordingly. After resolving the DNS for the URL, the router checks for the shortest and robust path for processing the quest with the help of routing protocol. Some popular routing protocols include Routing Information Protocol, Open Shortest Path First, Border Gateway Protocol. After identifying the most suitable path for the request, the connection to the X stream server will be established. Encapsulation of User datagram protocol, IP and Ethernet takes place before sending it to the router for resolving DNS query. This essay makes a conclusion that the first section covered mandatory requirements as well issues that occur on physical layer connectivity. Likewise, we have discussed the Ethernet packet header along with its purpose in details. The next discussion was about CSMA/CD, as the request needs space to fulfill the execution. Next we have discussed the ARP command along with the discussion of a MAC address packet. Moreover, in the next section we have discussed the network layer connectivity and router functionality. We have also put some light on routing protocols and their functions. Furthermore, in the last section, DNS query construction is discusses along with socket connections by incorporating HTTP, TCP/IP, UDP and ARP for opening the X stream web page on the home user browser.

Mummers Parade Essay Example | Topics and Well Written Essays - 2500 words

Mummers Parade - Essay Example Historians believe that Mummers Parade is the only tradition that has lasted for a long time running fork festival in the United States. The parade usually consists of thousands of performers who spend months developing and rehearsing so that it will be enjoyable. They build costumes and scenery and make the parade to be perfect preparing for entire day moving their way up Broad Street where day drinking marks the event. For those who do not go for the parade choose to keep drinking the whole night and in the morning while others use the New Year Eve to move to other countries for leisure. People usually come to the parade by train, bike and others on foot carrying glasses and thermoses of beer so that they can wear their costumes which will depict foreign cultures. Some people who do not like to be associated with racism do not let their children to go to the parade since they say that the parade is a racist tradition that is usually carried from one generation to the next despite t he parade being banned. The participant of the parade dress like a person or a thing that they are not, where they colour themselves and others depicts creatures which are colourful though they are white men they present simplistic cartoons which depicts foreign people and their culture showing that the parade is usually prepared to mark racist agendas in each and every year. During the 18th and 19th century   the slaves who were transported to United States and later employed in the plantation used to play instruments in the plantations.
