Odysseus Is Responsible For His Subsequent Predicament

Odysseus is responsible for his subsequent predicament, because he believes that his cleverness entitles him to a double standard of treatment. While this double standard is the cause of his punishment, Homer shows that the pursuit of kleos makes these beliefs justifiable. Odysseus expects others to respect major Greek traditions, yet throughout the episode with Polyphemus, he violates the tradition whenever he feels necessary. Greeks believe that food crimes are some of the worst possible crimes people can commit. Since the Greeks equated meat to status, stealing meat meant robbing someone of their status. Odysseus does not respect this custom when he tries to steal the cyclops’ livestock, which is how he ended up trapped in the cave in the first place. Yet when Polyphemus eats some of the men, an act that cyclopses do not identify as wrong, Odysseus is appalled. â€Å"We flung our arms to Zeus, we wept and cried aloud, / looking on at his grisly work—paralyzed, appalled† (9.331-332). Odysseus expects Zeus to uphold this double standard by punishing the cyclops, who was merely acting on instinct, while condoning an intentional food crime. Similarly, Odysseus expects Polyphemus to respect xenia, while Odysseus mocks the all-important tradition. He asks the cyclops to give a gift to his guests, guests he customarily eats, yet Odysseus mocks the tradition himself by giving the cyclops an ironic and harmful gift. Odysseus gives the gift of wine with the intent toShow MoreRelated Achilles Vs Odysseus Essay example3811 Words   |  16 PagesAchilles Odysseus Homers two central heroes, Odysseus and Achilles, are in many ways differing manifestations of the same themes. While Achilles character is almost utterly consistent in his rage, pride, and near divinity, Odysseus character is difficult to pin down to a single moral; though perhaps more human than Achilles, he remains more difficult to understand. Nevertheless, both heroes are defined not by their appearances, nor by the impressions they leave upon the minds of those aroundRead MoreEssay on The Odyssey21353 Words   |  86 PagesThe Odyssey Set in ancient Greece, The Odyssey is about the hero Odysseus long-awaited return from the Trojan War to his homeland, Ithaca, after ten years of wandering.

Global Warming Is The Rise - 1536 Words

Global warming is the rise in the earth’s average atmospheric temperature. When sunlight heats the ground surface, it releases most of the solar energy it has absorbed as infrared radiation. Then what is known as the â€Å"greenhouse effect† occurs, this is where the gases in the atmosphere absorb the re-radiated infrared radiation and the escape of these gases being released into space is prevented. As long as the composition of greenhouse gases in the atmosphere does not change, the heat in the atmosphere will remain constant by releasing the contained heat into space. It has been noted that greenhouse gases, such as carbon dioxide, water vapor, and methane, have been increasing steadily since the early 90’s, and around this time the average†¦show more content†¦In the year of 2012 alone, we had major record breaking events happen, we had the hottest January to June ever recorded in the continental United States. There were more than 22,000 daily high temperature records tied or broken, the largest drought declaration in over 50 years, one of the most destructive freak derecho storms in history, as well as fires in Colorado that destroyed more than 700 homes. ( www.nrdc.org ) Was this the cause of the human actives, natural events, or was it a part of the normal climate cycle, or could it have even been a combination of all three. There is an abundance of evidence that the global climate is warming, but the exact causes are unknown, one susceptive cause is actives of mankind. There are many different studies that show the level of greenhouse gasses in the atmosphere has increased since the second half of the 18 century also known as the Industrial Revolution. This is the time mankind started to make their carbon footprint on the environment. This footprint included technological changes such as the use of raw materials, new energy sources, the invention of new machines, new organization of work known as the factory systems, improvements in transportation and communication. While these actives have caused an increase in the amount of carbon dioxide, water vapor, methane and other pollutants that have affected the atmosphere, theShow MoreRelatedGlobal Warming is on the Rise Essay example766 Words   |  4 PagesWithin the last few years, there has been an alarming increase in global warming which refers to â₠¬Å"the phenomenon of greenhouse gas levels in the atmosphere to increase caused by human activities† (Maslin,2007).

Purpose of Power System Protection free essay sample

Purpose of POWER System protection The purpose of any power system is to generate, transmit, and distribute electricity to the consumer in a manner that is safe, reliable, and economical; both in the short and long term. Under normal operating conditions, the currents, voltages, power, and energy associated with such systems are all matched to meet the system’s design requirements with respect to reliability, quality, safety, and economy. To ensure maximum returns on the large or expensive investments in the components which go to make up the power system and to keep the customers satisfied with reliable (i. e. , adequate and secure) service, the power system must be kept in operation continuously without major breakdowns and consequently without violating the design limits (because of abnormal currents, voltages, or power). This can be achieved in two ways: (i) Implement a system adopting/using components, which should not fail (i. . , failure-free components) and requires the least or nil maintenance to maintain the adequacy and security of supply. We will write a custom essay sample on Purpose of Power System Protection or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page By common sense, implementing such a system is neither economical nor feasible, except for small systems. (ii) Foresee or anticipate any possible/credible effects or failure events that may cause long term shutdown of a system, which in turn may take longer time to bring back the system to its normal course. The main idea is to restrict or minimise the disturbances during such failures or events to a limited area and continue power supply in the balance/unaffected areas. The second approach is the one commonly used in practical power systems. To realise it, special equipment is normally installed to continuously monitor the power system to detect undesired conditions that present a threat to system reliability (adequacy and security) and take (initiate) action to remove the threat from the system with minimal adverse effects (i. e. detect abnormalities that can possibly happen in various sections of a power system, and to isolate affected sections so that the interruption of supply is limited to a localised area in the total system covering various areas and damage to expensive electrical equipment is limited and safety of personnel provided). This special equipment used to detect such possible failures or faults and initiate their removal is referred to as â€Å"protective equipment or device† and the system that uses such devices is termed as â€Å"protection system or scheme†. Thus, the objective of protection in a power ystem is to minimise the risk of damage to equipment, risk of life threat to personnel, and risk of supply interruptions or loss of service to unaffected portions of the system when faults and other abnormal conditions occur. Protective devices do not, therefore, prevent a fault or any other adverse condition from occurring in the system; they only mitigate or avert the consequences of such conditions whenever they occur through quick isolation or removal of the problem. The typical effects or consequences of fault conditions are discussed in the following section. Summary: There are several reasons to use protective devices in power systems:- (i) to provide alarm when measured process or quantity limits are exceeded, thereby allowing operators an opportunity to intervene with corrective actions; (ii) to isolate faulted equipment or circuits from the remainder of the system so that the system can continue to function; (iii) to limit damage to faulted equipment by quickly isolating from the system and hence reducing the duration of the problem; (iv) to minimise the possibility of fire or catastrophic damage to adjacent equipment; (v) to minimise hazards to personnel; and vi) to provide post-fault information to help analyse the root cause.
