Passage from Mark Twains The Adventures of Huckleberry Finn Research Paper Example

Passage from Mark Twains The Adventures of Huckleberry Finn Research Paper Example Passage from Mark Twains The Adventures of Huckleberry Finn Paper Passage from Mark Twains The Adventures of Huckleberry Finn Paper it makes it easier for us to believe that it is Huck an uneducated young man that is telling the story, instead of Mark Twain himself. This does not mean that Mark Twains own personality and opinions do not shine through. Huckleberry Finns naivety and lack of education make him the perfect tool for Twain, who uses him to poke fun at various aspects of 19th-century American society. In the extract, Huck is marvelling at the quality of Emmeline Grangerfords poetry, saying [i]f Emmeline Grangerford could make poetry like that before she was fourteen, there aint no telling what she could a done by-and-by. Earlier in chapter XVII, the reader is served a sample of Emmelines poetry, the Ode to Stephen Dowling Bots, Decd. , which is mediocre at best, and incredibly melodramatic. It becomes obvious that while Hucks admiration is genuine, Twain is being satirical and holds that kind of literature in contempt. The character of Emmeline Grangerford is based on a poet called Julia A. Moore (Hess: 2003a; Blair: 1996). Moore was known as the sweet singer of Michigan and wrote dreadful poetry. When Huck says she could write about anything you choose to give her about, just so it was sadful, it is an obvious reference to Julia Moore. Some of Moores subjects of choice were deaths of neighbours, deaths of neighbours children, heroic soldiers being killed in the Civil War (Blair: 1996) Mark Twain counted Moore amongst his favourite poets because she was always able to make him laugh. She tried very hard to make her poems as sad and tragic as possible, but in the end, they turned out funny, just as Emmelines tributes did. Twain is not only making fun of Julia Moore: he is attacking the whole movement of romanticism. Romantic gothic works such as Edgar Allan Poes poetry and Washington Irvings The Legend of Sleepy Hollow were popular in Victorian America. Death and mourning were subjects that were often written about in Romantic literature, and were treated in an overdramatic, histrionic manner. Emmeline Grangerfords horrible poetry serves as a caricature of Romantic literature and shows how Mark Twain really felt about it. Twain was more of a realistic writer, and preferred to describe events and people as they truly were. His use of the vernacular, which I have mentioned earlier, amplifies the feeling of reality the reader gets while reading The Adventures of Huckleberry Finn. Romantic literary works were written in a very formal style, with many superfluous adjectives and adverbs. Twain cuts out anything unneeded, and focuses instead on the storyline, on dialogues, and on the relationships between characters. At one point in the extract, Huck says that after once, Emmeline hung fire (hesitated) on a rhyme in one of her tributes. Because of this, the undertaker got to the dead body before her, and Emmeline arnt ever the same, after that; she never complained, but she kind of pined away and did not live long. Emmeline used too much time on her poem and she could not recite it in front of the dead person. Twain is insinuating that this made her so upset that it killed her. This can mean two things: either that Emmeline was extremely narcissistic, or that she was too sensitive for her own good. It seems like Twain is using Emmeline to represent the mass of Romantic authors. One can probably assume that he is accusing Romantic writers of taking themselves, and life, too seriously. Later in the passage, Huck feels sorry that Emmeline does not have her own tribute, and tries to write a couple of verses about Emmeline. For some reason, he [can]t seem to make it go somehow. It is evident that Huck feels very sorry for Emmeline, and truly cares about her and her family: I liked all that family, dead ones and all, and warnt going to let anything come between us. I believe that Mark Twain is saying that Romantic writers are phony, or, at least, writing about fake emotions. Hucks feelings about the Grangerfords are genuine. The naivety and childlikeness of Huck do not allow him to pretend he is feeling anything he is not, and therefore, he cannot write anything like Emmelines poetry. Huck also mentions that Emmelines pictures had been aggravating him, something which further proves that Huck is definitely not a Romantic. He is horrified at the macabre elements in Emmelines art. The Romantic movement was very present in Victorian America, and not only in literature. When Huck says: The neighbors said it was the doctor first, then Emmeline, then the undertaker Twain is really telling the reader about the attitude a lot of people had about death around that time. In Puritan America (17th-18th century), people welcomed death, because it was a way out of the hardships of life. On the other hand, they feared its consequences: death was a passageway into a world which could be immeasurably better, or, if one were not among the chosen ones, unbearably worse. (Hess: 2003b) In the 19th century, the Romantic movement came to America from Europe, and people started seeing death in a very different way. By reading Romantic literature, people became increasingly fascinated with death and the mystery that surrounds it. Death was a big part of these peoples lives, and they confronted it head-on. Taking pictures of dead people in their coffins was extremely common in America in the 19th century (Hess: 2003c). Emmeline is a product of her time: she wishes to see death, to write about it, and to draw pictures about it (as described earlier in Chapter XVII). Therefore, when somebody dies, she is very quick to arrive on the scene. It is not specified how long ago Emmeline died, but the family is obviously still in mourning: They kept Emmelines room trim and nice and all the things fixed in it just the way she liked to have them when she was alive, and nobody ever slept there. Mourning was a very important part of life in Victorian America, and would last for years (Hess: 2003d). Twain seems to be writing about this to further define the Grangerfords as Romantics. Huck touches on the subject of slavery near the end of the passage. He mentions that the Grangerfords own many slaves, and also that the old lady Grangerford spends a lot of time reading her Bible in Emmelines room. Mark Twain is drawing attention to a paradox: how can slave owners consider themselves Christians, when they are buying and selling human beings as if they were animals? Huck seems oblivious to this contradiction, at least for the time being. He is casually stating facts, and does not seem disturbed by them. He is even wondering why the niggers do not clean Emmelines room. This may seem strange to the reader, since Hucks best friend is a runaway slave. I think that Twain is denouncing the indifference of the American people to slavery. It is so common to own slaves in the South before the Civil War that most White people fail to see the great injustice that is being done. HReligion was central in Victorian America, and people prided themselves on attending Church regularly and being able to recite passages of the Bible. Yet many of these people owned slaves, and throughout the whole novel, Twain shows the reader many Christians doing ungodly acts. By doing so, he is attacking hypocritical Christians. He is saying that Christianity is not about keeping up appearances, but about doing onto others as you would have them do onto you. In the last paragraph of the extract, Huck resumes describing the parlour, something he had started to do earlier in Chapter XVII. Huck has never really lived in a house, apart from the Widow Douglas house, which was simple and sparsely furnished. Therefore, Huck is really impressed at the Grangerfords house, which is lavishly decorated, with beautiful curtains and pictures of castles with vines all down the walls . Mark Twain is deliberately making the Grangerfords house look as tacky as possible, to mock the Victorians taste. It was typical for people at that time to pretend they were wealthier than they really were, by decorating their homes in an exaggerated manner, with objects that seemed expensive. They did so because they aspired to a higher status in society. Twain is poking fun at this, and implying that they are not fooling anybody, except very naive people such as Huckleberry Finn. In conclusion, this passage deals with a lot of important subjects, such as slavery and religion. These are also approached in other chapters. The main theme in this particular extract is Romanticism and Twains dislike of it. Twain is using the naive, wide-eyed Huckleberry Finn to mock the 19th-century American society and its exaggerated emotionalism. He is suggesting that this society is phony and that Huck is probably better off uncivilised. To make Huck more credible as an uneducated and young narrator, Twain writes in a Southern vernacular dialect. This also makes The Adventures of Huckleberry Finn stand out from other literary works published in the 19th century, which were written in a much more formal kind of American English.

How Does Regenerative Braking in Hybrid Cars Work

How Does Regenerative Braking in Hybrid Cars Work Hybrids and all-electric vehicles create their own power for battery recharging through a process known as regenerative braking (regen mode). Weve explained what regenerative braking is and how the process works in general terms, but many folks are interested in the deeper nuts and bolts of electricity generation. They understand that in a hybrid or all-electric vehicle the word regenerative, in terms of regenerative braking, means capturing the vehicles momentum (kinetic energy) and turning it into electricity that recharges (regenerates) the onboard battery as the vehicle is slowing down and/or stopping. It is this charged battery that in turn powers the vehicles electric traction motor. In an all-electric vehicle, this motor is the sole source of locomotion. In a hybrid, the motor works in partnership with an internal combustion engine. But that motor is not just a source of propulsion, its also a generator. Any permanent magnet motor can operate as either a motor or generator. In all-electrics and hybrids, they are more precisely called a motor/generator (M/G). But the technologically curious want to know more, and theyll often ask How, and by what mechanism or process, is the electricity created? Its a good question, so before we get started explaining how M/Gs and regenerative braking work in hybrids and electric vehicles, it is important to have basic knowledge about how electricity is generated and how a motor/generator functions.   So How Does a Motor/Generator Work in an Electric or Hybrid Vehicle? No matter the vehicle design, there must be a mechanical connection between the M/G and the drivetrain. In an all-electric vehicle, there could be an individual M/G at each wheel or a central M/G connected to the drivetrain through a gearbox. In a hybrid, the motor/generator could be an individual component that is driven by an accessory belt from the engine (much like an alternator on a conventional vehiclethis is how the GM BAS system works), it could be a pancake M/G that is bolted between the engine and transmission (this is the most common setupthe Prius, for example), or it could be multiple M/Gs mounted inside the transmission (this is how the two-modes work). In any case, the M/G has to be able to propel the vehicle as well as be driven by the vehicle in regen mode. Propelling the Vehicle with the M/G Most, if not all, hybrids and electrics use an electronic throttle control system. When the throttle pedal is pushed, a signal is sent to the onboard computer, which further activates a relay in the controller that will send battery current through an inverter/converter to the M/G causing the vehicle to move. The harder the pedal is pushed, the more current flows under the direction of a variable resistance controller and the faster the vehicle goes. In a hybrid, depending upon load, battery state-of-charge and the design of the hybrid drivetrain, a heavy throttle will also activate the internal combustion engine (ICE) for more power. Conversely, lifting slightly on the throttle will decrease current flow to the motor and the vehicle will slow down. Lifting further or completely off the throttle will cause the current to switch direction - moving the M/G from motor mode to generator mode - and begin the regenerative braking process. Regenerative Braking: Slowing the Vehicle and Generating Electricity This is really what the regen mode is all about. With the electronic throttle closed and the vehicle still moving, all of its kinetic energy can be captured to both slow the vehicle and recharge its battery. As the onboard computer signals the battery to stop sending electricity (via the controller relay) and start receiving it (through a charge controller), the M/G simultaneously stops receiving electricity for powering the vehicle and starts sending current back to the battery for charging. Remember from our discussion on electromagnetism and motor/generator action: when an M/G is supplied with electricity it makes mechanical power, when its supplied with mechanical power, it makes electricity. But how does generating electricity slow the vehicle? Friction. Its the enemy of motion. The armature of the M/G is slowed by the force of inducing current in the windings as it passes over the opposing poles of the magnets in the stator (its constantly battling the push/pull of the opposing polarities). It is this magnetic friction that slowly saps the vehicles kinetic energy and helps scrub off speed.
