What Makes A Motor Work How Does It Energize Things The...

Motors have quickly become an elemental apparatus in the operation of nearly everything in this world. Trains that take people to work, assembly lines that pump out food, toys and an assortment of commodities, cars, trucks, planes†¦The list goes on. But more importantly, how does a motor work and how does it energize things the way it does? Why is the motor still being used as opposed to some newer technological innovation that could potentially be more efficient? There are two distinctions that are subtle but nonetheless important, and that is the difference between and electric motor and an engine. The first(most glaringly at that) obvious difference is that an engine is often fueled with some kind of fossil fuel, such as petroleum†¦show more content†¦Since the scientific revolution, scientists and witty minds alike tried to come up with early precursors of the motor. However, quite a bit of the technology used today to produce items such as motors and engines were not in existence back then. The first resemblance of a motor can be seen in Andrew Gordon’s electrostatic machines that were produced in the 1740’s. However, this is not exactly a hallmark discovery that revolutionized the field whatsoever. What was ground-breaking in the field, however, was the discovery of Ampere’s law in 1820 which displayed the production of mechanical force via interactions of an electric current within a magnetic field. With the discovery of Ampere’s law came two impressive innovations in the field of electric motors and engines that slowly bring us closer to the ones of today: Barlow’s wheel and Michael Faraday’s 1821 electromagnetic experiment. Faraday’s experiment build directly upon the theory that Ampere concocted the year before, and it displayed electromagnetic activity being able to convert electrical energy to mechanical energy. This was shown by a loose wire being dipped in mercury with a magnet at the end. A current rose through the wire via the magnet, and the wire rotated around it, displaying that the wire can facilitate a close magnetic field. These attempts were not actually very productive, however. They didn’t resemble any

Psychoanalytic Analysis on the Black Cat Free Essays

A Psychoanalytic Analysis on The Black Cat By Edgar Allan Poe First of all, let us go into the world of â€Å"The Black Cat† and delve into the inner workings of the dark side of the human mind. ‘The Black Cat’ is a story that leaves the reader perplexed to some extent. It certainly contains all the ingredients necessary to satisfy the appetite of any Poe enthusiast – an enigmatic narrator, alcohol , mutilation, strangulation, murder, and, last but not least, one of Poe’s slight obsessions, perversity In the story, The Black Cat, there is a lot of symbolism regarding hidden attributes of his life. We will write a custom essay sample on Psychoanalytic Analysis on the Black Cat or any similar topic only for you Order Now The black cat itself represents not only a hidden meaning but a meaning the narrator wished to keep hidden. The black cat symbolizes the narrator’s or Poe’s alcoholism. Edgar Allen Poe has been accused of being an alcoholic throughout his life and it may have actually lead up to the cause of his death. The short story may give a subtle view at Poe’s fight with the disease and the disease’s eventual triumph. The black cat may not only be a symbol of the alcoholism that Poe faces but perhaps just his conscious in general regarding most anything deviant. By depicting mental conflict, Poe reveals the theme that the human mind would be healthy and alive if it were incapable of thought, but since it is a mind and does possess the power of introspection and self-knowledge, then that very power and knowledge spell its death. From this protagonist with conflicting thought, we may experience more or less Poe’s inner world of himself in which his mind is half mad and full of horror like the narrator of â€Å"The Black Cat†. Poe was afraid of the fits of temper that came over him while he was drinking. When sober he was a gentleman, courteous in any situation, and the very soul of gentility. When he was affected by alcohol, however, the suppressed rage that he felt for what he considered the injustices of a gross and unfeeling would expressed itself in vituperation and violence. In creating the narrator of â€Å"The Black Cat†, Poe distorted and exaggerated all the faults of his personality while drunk. Even though the narrator denies this, we becomes increasingly aware of his superstitious belief as the story progresses from the fact that he calls his cat, Pluto, who in Greek and Roman mythology was the god of the dead and the ruler of the underworld. One moment he will be in a perfect frenzy of violence, with nothing but curses and vituperation even for those he loves. Very quickly, however, he is overcome with remorse and is sorry for all that he has said and done. We can prove this by reading the following sentences: Who has not, a hundred times, found himself committing a vile or a silly action, for no other reason than because he knows he should not? Have we not a perpetual inclination, in the teeth of our best judgment, to violate that which is Law, merely because we understand it to be such? This spirit of perverseness, I say, came to my final overthrow. It was this unfathomable longing of the soul to vex itself—to offer violence to its own nature—to do wrong for the wrong’s sake only—that urged me to continue and finally to consummate the injury I had inflicted upon the unoffending brute. The narrator is not Poe, but Poe used details of his own experience in the character of the narrator. Indeed, Poe places the subconscious condition of the mind under investigation and probes beneath the surface of normal existence. What interests him most is the deep abyss of the unconscious and subconscious mental activity of the people, the subterranean recesses of the mind at work.

Causal analysis

Causal analysis-obesity Essay Greg Last, a local doctor, shared the following story about obesity, Ive been a physician for nearly forty years but it wasnt until Just recent years IVe seen staggering amounts of patients with chronic illnesses related to an inactive and overfed lifestyle, (Last). Here, in America obesity rates are on what seems to be an unstoppable incline. Recent statistics show that from 1980 to 2000 obesity rates more than doubled. It was then described as reaching epidemic proportions not much later by a prominent U. S. surgeon. Americans now consume 2,700 calories a day, bout 500 calories more than 40 years ago. In 2010, we still ranked as the worlds fattest developed nation, with an obesity rate more than double that of many European nations (Ambinder 4). Karen Ravn said, Now more than ever, we as parents and a nation must do something about the growth of obesity in our children. We must do more than Just talk, we must be concerned enough to act. Many Americans suffer long-term, negative effects because of obesity. Some may assume that the source of an obese nation is merely a struggle with proper nutrition and dieting. They are sadly misinformed. The causes of this illness that is sweeping the nation have been traced back to a lack of an education in nutrition, the vast number of unhealthy food options introduced to Americans on a daily basis, and an overall air of laziness and distaste for any form of physical activity. Because no ones lives are stress free, many find it hard to stay ahead of the looming obesity monster Just waiting for its chance to pounce. Though certain factors may not be able to be controlled, that doesnt mean that one should give up a well-deserved chance to elebrate life in a healthy, positive way (Ravn). As it was stated many do not realize or choose to take advantage of the power that they have over their lives. They believe that change is not possible or even probable. If this very outlook were to change all of America would feel its tremendous influence. As stated above our country is not in hopeless state; if not only the children, as the future of America, were educated as well as the parents, it would further ensure the optimistic outlook for this nation. Many adults have sheepishly admitted to taking one look at a food label and mmediately becoming discouraged by numbers, percentages, and words they simply dont understand (Ambinder 6). They end up going for the cheaper not to mention much less nutritious frozen snacks that their children seem to enjoy. Little do they know they are harming their children more than they are helping with these fat and sugar loaded treats. Elena L. Serrano once said, Parents often buy cheaply manufactured, energy-dense, sugary and salty snacks that crowd grocery store shelves and freezers to simply save time and effort. Although these treats may be asty they slowly destroy ones health. If adults only understood what they were buying we would see a dramatic decrease in the ever increasing rate of obesity in America. Another cause known to lead to obesity, especially in children, is the abundance of fast foods that although may be quick and easy, as stated in the name, quite honestly also quickly and easil y fill stomachs with unhealthy oils, fats, sugars, and of course mounds of salt. It is bad enough that these foods are being shelled out for every meal in the home but when they are introduced as a suitable eal at scnool t , I Is out 0T control. Many students slmply graD a greasy slice 0T pizza and walk straight past the salad bar without a second though. Although there have been recent changes to attempt to better lunches by the first lady, Michelle Obama, that have made an impact, further advances may not only be possible but absolutely necessary. A recent survey by parents of elementary school children shows their wishes to improve school cafeteria lunches to be not only nutritious but also delicious. .ubf759fdc0c594b01251b22743ff7686a , .ubf759fdc0c594b01251b22743ff7686a .postImageUrl , .ubf759fdc0c594b01251b22743ff7686a .centered-text-area { min-height: 80px; position: relative; } .ubf759fdc0c594b01251b22743ff7686a , .ubf759fdc0c594b01251b22743ff7686a:hover , .ubf759fdc0c594b01251b22743ff7686a:visited , .ubf759fdc0c594b01251b22743ff7686a:active { border:0!important; } .ubf759fdc0c594b01251b22743ff7686a .clearfix:after { content: ""; display: table; clear: both; } .ubf759fdc0c594b01251b22743ff7686a { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ubf759fdc0c594b01251b22743ff7686a:active , .ubf759fdc0c594b01251b22743ff7686a:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ubf759fdc0c594b01251b22743ff7686a .centered-text-area { width: 100%; position: relative ; } .ubf759fdc0c594b01251b22743ff7686a .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ubf759fdc0c594b01251b22743ff7686a .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ubf759fdc0c594b01251b22743ff7686a .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ubf759fdc0c594b01251b22743ff7686a:hover .ctaButton { background-color: #34495E!important; } .ubf759fdc0c594b01251b22743ff7686a .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ubf759fdc0c594b01251b22743ff7686a .ubf759fdc0c594b01251b22743ff7686a-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ubf759fdc0c594b01251b22743ff7686a:after { content: ""; display: block; clear: both; } READ: Is Government Dominated By Business EssayDavid Kessler, the author of The End of Overeating, accuses the food ndustry of, manipulating the levels of sugar, salt, and fats in food in order to create a neurochemical addiction. He continues with, Food companies like to keep us happy, and theyVe fgured out which molecular combinations make our mouths water. Over time, these hyper palatable foods change our brain chemistry in ways that make us overeat (Warner 3). By introducing healthy foods at a young age this neurochemical addiction may be prevented and better habits may be produced. A third possible cause to the obesity epidemic other than bad eating habits, is the lack f activity in a day to day basis. In this day and age of technology, many people are used to easy and immediate outcome through a simple action. Because exercise does not fit into the category above, numerous individuals are deterred when they are faced by the more rigorous actions required in physical activity expecting instantaneous results. By implementing a fun exercise routine in every home many problems could be solved. The rise in obesity is associated with a rogues gallery of individual, social, and technological factors. The Big Two, as scientists call the eading factors, are reduced exercise and increased food consumption: Americans are ingesting more and more calories than theyre burning (Spradlin). Many view exercise as a big hoopla and use it as an excuse to not participate in it. Being active doesnt have to be running a marathon it can be something that is an enjoyable hobby that involves some sort of physical movement. Being active doesnt require any extra money, unlike paying to take nutrition classes or going on crash diets. Anyone can choose to exercise, everyone is capable. All that is necessary for one to become hysically active is a small lifestyle change that would make all the difference. As with nutrition, parents can be instrumental in discouraging sedentary activities, mainly by reinforcing the positive benefits of physical activity. For example, parents can praise children for playing outside after school. Participating in a sport with a child and organizing family activities, such as a bike hike or even a walk after dinner, can provide children with powerful inducements to modify their behavior (Haney). The biggest known cause of obesity could be eliminated simply by encouraging egular exercise in the home and at school. There are also some very serious effects of obesity. Everyday additional obese patients are admitted into medical care. Health care prices have risen through the roof. People who are suffering from obesity pay more than 42% more on health insurances because of the risk of diabetes and chronic diseases, among other health risks. Out of every 5 patients to enter a health care building, whether it is a hospital or doctors office, 3 are said to be unhealthily overweight (Spradlin 2). Marc Ambinder said, In short, even as the ation is convulsed by a political struggle to reform health care, no effort to contain its costs is likely to succeed if we cant beat obesity. Health care reform has been a hot topic lately within the U. S. As times gone on, it has become blatantly obvious tnat nealtn care Isnt necessarlly tne only tnlng tnat needs to De reTormea, D American people as well, to ensure overall wellbeing of Americans. Health care problems cannot be absolved until obesity is conquered. It has been proven that those suffering from obesity are more subject to, among other things, depression. Because of this they are likely to miss more work, school, and additional commitments or activities. Suicidal tendencies have also been linked to the feelings of depression and low self-esteem that accompany obese people (McVeigh). Serrano said, Improper weight and diet strongly correlate with chronic diseases, and an often over looked, but very serious problem, that is an issue of life and death. That issue is one of people feeling trapped and depressed who then look to suicide as their only What can be done to stop the raging forward motion of obesity? How scape could America change without Americans learning how to change themselves and their lifestyles? Should the obesity rise continue, our nation will only get worse. Obesity proposes very serious health issues, including mental, emotional and even social problems. As Karen Ravn said, Now more than ever, we as parents and a nation must do something about the growth of obesity in our children. We must do more than Just talk, we mu st be concerned enough to act. Only we can change our lives by taking charge and acting. Therefore, obesity is a growing problem hroughout the nation that causes many harmful effects. .u8ab39900be33b16aa9a0f260aa36d270 , .u8ab39900be33b16aa9a0f260aa36d270 .postImageUrl , .u8ab39900be33b16aa9a0f260aa36d270 .centered-text-area { min-height: 80px; position: relative; } .u8ab39900be33b16aa9a0f260aa36d270 , .u8ab39900be33b16aa9a0f260aa36d270:hover , .u8ab39900be33b16aa9a0f260aa36d270:visited , .u8ab39900be33b16aa9a0f260aa36d270:active { border:0!important; } .u8ab39900be33b16aa9a0f260aa36d270 .clearfix:after { content: ""; display: table; clear: both; } .u8ab39900be33b16aa9a0f260aa36d270 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u8ab39900be33b16aa9a0f260aa36d270:active , .u8ab39900be33b16aa9a0f260aa36d270:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u8ab39900be33b16aa9a0f260aa36d270 .centered-text-area { width: 100%; position: relative ; } .u8ab39900be33b16aa9a0f260aa36d270 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u8ab39900be33b16aa9a0f260aa36d270 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u8ab39900be33b16aa9a0f260aa36d270 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u8ab39900be33b16aa9a0f260aa36d270:hover .ctaButton { background-color: #34495E!important; } .u8ab39900be33b16aa9a0f260aa36d270 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u8ab39900be33b16aa9a0f260aa36d270 .u8ab39900be33b16aa9a0f260aa36d270-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u8ab39900be33b16aa9a0f260aa36d270:after { content: ""; display: block; clear: both; } READ: Taming of the Shrew1 EssayObesity can be not only be slowed but also eventually prevented by parents becoming better educated to make wiser decisions nutritionally for both themselves and their children. Not only should Americans be educated but they should use that education to make smart decisions when dining out as well as in the home. The final factor to kill off obesity is the integration of some sort of physical activity on a regular basis. By eliminating the causes of obesity, Americans will no longer have to fear the chronic illnesses or epression that follow in their wake. Works Cited Ambinder, Marc. Beating Obesity.
