Antoine Lavoisier Essays - Chemical Elements,

Antoine Lavoisier Antoine Lavoisier (1743-1794) Antoine-Laurent Lavoisier (lah vwah ZYAY) was one of the best-known French scientists and was an important government official. His theories of combustion, his development of a way to classify the elements and the first modern textbook of chemistry led to his being known as the father of modern chemistry. He contributed to much of the research in the field of chemistry. He is quoted for saying, "Nothing is lost, nothing is created, everything is transformed." Lavoisier was born in Paris, France on Aug. 26, 1743. When he was eleven years old he attended a college called Mazain. For Lavoisier's last two years in college he found a great deal of interest in science. He received an excellent education and developed an interest in all branches of science, especially chemistry. Abbe Nicolas Louis de Lacaill taught Lavoisier about meteorological observation. On 1763 Lavoisier received his bachelor's degree and on 1764 a licentiate which allowed him to practice his profession. In his spare time he studied books all about science. His 1st paper was written about gypsum, also known by hydrated calcium sulfate. He described its chemical and physical properties. He was elected to the French Academy of Sciences in 1768. On 1771 he married Marie Anne Pierrette Paulze. She helped Lavoisier by drawing diagrams for his scientific works and translating English notation for him. Unlike earlier chemists, Lavoisier paid particular attention to the weight of the ingredients involved in chemical reactions and of the products that resulted. He carefully measured the weights of the reactants and products. He noted that the weight of the air in which combustion occurred decreases. He found that when the burning material combined with the air somehow and that the air weighed less. Lavoisier found that the weight of the products of combustion equals the weight of the reacting ingredients. This observation became known as the law of conservation of mass (or matter). He repeated many of the experiments of earlier chemists but interpreted the results far differently. On 1772 he was studying on combustion, which he is most known for in science. Lavoisier presented an important memoir on conversion of water into earth evaporation. This brought him to the Oxygen Theory of Combustion. On 1774 Lavoisier carried out experiments on calcinations of tin and lead and confirmed the increase of weight of metals on calcinations from combustion of air. By demonstrating the nature of combustion, he disproved the phlogiston theory. The phlogiston theory stated that all flammable materials contained a substance called phlogiston. According to this theory, materials gave off phlogiston as they burned. Air was necessary for combustion because it absorbed the phlogiston that was released. This was thought at the time to be a fact. Lavoisier showed this theory to be false and made oxygen the reason that things burned, not phlogiston. Lavoisier burned textbooks that supported the theory. He was trying to make a point that the phlogiston theory was invalid and oxygen is the new answer to combustion. He laid the framework for understanding chemical reactions as combinations of elements to form new materials, or products. He concluded that combustion results from the rapid chemical union of a flammable material with a newly discovered gas, which he named "oxygen", previously known as "dephilogisticated air." The word "oxygen" means acid producer. Lavoisier and others had found that oxygen is a part of several acids. Lavoisier incorrectly reasoned that oxygen is needed to make all acids. He developed endings of the degree of oxygen by adding certain ending such as -ic or -ous. With French astronomer and mathematician Pierre Simon Laplace, Lavoisier conducted experiments on the respiration in animals. Their studies showed a similarity between ordinary chemical reactions and the processes that happen in living organisms. These experiments were the basis for the science now known as biochemistry. Lavoisier also helped to develop a system for naming chemical substances based on their composition. This system is still in use. He made the very first modern chemistry text named Trait? el?mentaire de chimie (Elements of Chemistry). Many consider it the first textbook on modern chemistry. Here for the first time the elements are laid out systematically. His list included many compounds, which were thought to be elements at the time. Lavoisier worked out reactions in chemical equations that respect the conservation of mass. As a government official, Lavoisier was successful in creating agricultural reform, serving as a tax collection official, and overseeing the government's manufacture of gunpowder. On 1775 he was made commissioner of gunpowder.

Analysis N.Sparks True Believer Essay Example

Analysis N.Sparks True Believer Essay Example Analysis N.Sparks True Believer Essay Analysis N.Sparks True Believer Essay Dariya Glazova, group 402 Nicholas Sparks  «True Believer » The text under stylistic analysis presents the excerpt from the novel  «True believer » written by Nicholas Sparks. In this passage the author touches upon the issue of generation gap. He contrasts the grandmother, Doris McClellan, with her grandchild, Lexie. It is known that the adults like to teach their children how they should live their life and Doris isn’t exception. From the very beginning the reader can guess that the granny and her granddaughter are polarities. The author employs the parallel construction  «For Doris, the reason was †¦ For Lexie, the reason was†¦Ã‚ » to enhance this idea. Also we can see that the relationship between these two women are very close because even Lexie is angry with her granny’s interference in her life she loves her with her whole heart. To show that the grandmother’s existence is full of taking care of her lovely treasure the author uses the following choice of word: she meant no harm, frequently wondered aloud, all of her hemming and hawing and such like things. Among the other problems of society Nicholas Sparks raises the question of crisis of women of thirty years in this extract. He draws the reader’s attention to the fact that at her thirties Lexie  «hadn’t settled yet » and she is still in the search of her knight in shining armour. This special kind of her happiness, on the other hand she wants to meet the right guy as every normal girl or woman, is described by the author in the only one masterfully collected word  «her man » and this idea is also strengthened by the graphical expressive mean- the italics of the possessive pronoun her. The powerful effect produced by these stylistic devices is quite unquestionable. But she wants not only to be with the right guy but she wants the only one man who possible never has existed in the real world because he is a figment of her imagination which is created by herself according to the glamorous magazines overstuffed her library. This idea manifests itself through such demands to her chosen one as  «both sensitive and kind, at the same time sweet her off her feet, offer to rub her feet after a long day, challenge her intellectually, buy her flowers for no reason ». Furthermore Sparks draws the parallel between the past and the present which are embodied by main characters. Here we can see that the writer depicts the moral principles of women of the past and the representatives of the gentle sex of modern world. With having a keen eye for details the author claims that in the past women married men who were  «decent, with some principles and had a good job » but modern daughters of Eve want to feel passion for somebody as well and it is not easy for them to get married and find someone special in the whole world. The author’s object in employing the antithesis is quite evident because he enhances the desired effect with the help of this stylistic device. To the conclusion I’d like to wish all the women to find their partner in life but don’t have allusion about your eligible bachelor because everybody architects of his own fortune and also I completely agree with Nicholas Sparks that the excitement alive in the relationship is mostly up to the woman. if I’m wrong, correct me.

JetBlue Airlines Research Paper Example | Topics and Well Written Essays - 1250 words

JetBlue Airlines - Research Paper Example Other airline companies that JetBlue has formed alliances with include Lufthansa, OpenSkies, American Airlines, Virgin Atlantic Airways, Jet Airways and South African Airways among others. In its effort to maintain strong positive relationship with its clients, JetBlue emulates strong advertising strategies by use of local newspapers, televisions and social media including YouTube and Hulu.com (Laurence, 2008). The company has adopted advertising phrases for example we like you too and unbelievable. As the result of extensive marketing strategies, the company has benefited from strong customer awareness and distinctive positioning aspects that have made it to attain a competitive edge in the market. One of the notable core values that make JetBlue Airline to be the option of US travelers is its strong binding with Customer Bill of Rights. According to the company management, the company has to refund the customer’s funds in the event of a cancellation or delay of flights. JetBlue airlines suffered two major incidents that did not result to any casualty. The first one is the 2005 emergency landing of Flight 292 at Los Angeles Airport. The second one happened on Flight 191 when the traveler subdued the captain and locked him out of the cockpit after a panic attack. One of the major weaknesses of JetBlue Airline is that it does not have large number of hubs as compared to other airlines in the US. As a result, the company is not in a position to effectively compete with its rivals that includes Southwest, Pan AM, Northwest, American and Delta among others. This inadequacy in the number of available hubs for the company to use makes it impossible to attend to most of its customers from various locations in the United States. For instance, the company cannot attend to its customers on the west properly without bringing in the services of

In Time Movie Review

In Time Movie Review In Time starring Justin Timberlake as Will Salas, is what I believe to be an eye-catching action thriller with every right to be on your must watch list. Breaking onto the scene just as the occupy wall street movement began to gain traction on October 28th 2011. Director Andrew Nicoll, did a fantastic job in displaying what can happen to society when the rich become driven by greed. This film was produced by Regency Enterprises and initially released in theaters. Although, it can be now viewed through everybodys favourite streaming platform Netflix. In Time finds itself to be extremely unique, separating itself from other action thrillers. People are free to live carelessly until they reach twenty-five and thats when their clock starts ticking. This is when you are given one more year to live and when that time hits zero, you time out. This results in people having to hustle or face death evident by Will saying You dont generally sleep in.. when questioned, how do people survive like this. The film is portraying Will Salas a man living day to day on his remaining time. Somehow finding himself in the possession of centuries and accused of murdering the man who gave him the time. He left him a final note reading Dont waste my time shortly before timing out himself. Leading to Will going onto finding himself falling in love with Olivia. A foil of himself rich, with time beyond his wildest dreams, edgy and against her father. Furthermore, going onto robbing time for the poor acting as a robin hood figure and escaping the timekeeper. As an action thriller movie, I was very impressed in comparison to other films that fall into the same category such as Furious Seven and Mad Max: Fury Road. In Time was not lacking in the creativity department of the plot. It was not simply a high budget movie set out to grab money. The story had depth and layers, moving from one objective to another. Unlike Mad Max: Fury Road which just focused on an escape and traveling with fuel with minor irrelevant details, coming off as a bit all over the place. In addition, Furious Seven which also has a messy plot comes off worse as a cash cow series. With simply no substance and just explosions with lack luster sound effects to tag along. This truly unique piece, does a great job of setting itself from other films within the same genre of action and thriller. I personally, am yet to see a more creative film well executed. It did a fantastic job in tying in some realism and science fiction. In what society could possibly get too at the point of over population and the rich wanting poor people to remain impoverished. I also believe the film had a very rich and satisfying production, featuring well edited settings whether it was in the corporate city, desert or the ghetto. Along with the soundtrack which added another sense to the film sometimes giving me goosebumps and not allowing my eyes leave the screen to see just what was about to happen. Furthermore, Craig Armstrong did an amazing job in the sound production truly triggering my emotions inside and anticipation for what was to happen. The only thing I wish this film included was more insight into how society got to the point of where time has taken the place of mon ey and how its ties directly with your life. I believe In Time to have included many themes such as one being time is money. Which can be taken in the literal sense of this movie because time acts as a currency and is a crucial part of everyday life, running the world. Along with that, Henry Hamilton played by Matt Bomer say For a Few to be immortal many must die this is relevant in this film since the rich only get richer and live forever, while the less fortunate wither away and struggle day to day. The themes in this movie are quite sad and can get the viewer really conflicted thinking about todays world and why some that can afford to give hoard. In conclusion, I believe this film is a must watch for any thriller fans. The balanced cast including Justin Timberlake, Olivia Wilde and Matt Bomer made for a great addition. Along with, the great use of a unique plot and great special effects. The use of imagery and themes also really gets the viewer thinking really making this film a must to any movie lover and person with an open mind.

Melodrama Essay -- Literary Analysis,Steve Neal, Christine Gledhil

There are many debates in Film Studies over what films count as melodramas. Film scholar Steve Neale’s essay, â€Å"Melodrama and the Woman’s film,† describes the paradigm shift that melodrama has experienced from the Silent era to the 70’s. On the other hand, Christine Gledhill’s essay, â€Å"Rethinking Genre† and â€Å"The Melodramatic Field: An Investigation,† suggest that melodrama is just a mode and, not, in fact, a genre. While Thomas Elsaesser’s essay â€Å"Tales of Sound and Fury: Observations on The Family Melodrama,† identifies the different types of melodrama. But what is a true form of the melodrama genre? At first, it might be difficult to understand why an animated film such as Curious George made my nephew ask me why he felt like crying when the monkey was separated from his zookeeper, and proceeded to ask why the film made him sad. What my little nephew didn’t know was that I also cried. Melodrama tic films are those that make you cry: films that have an essence of verisimilitude, evoke pathos, and use music to accentuate the ‘drama.’ In this essay, I will take elements of Neale, Elsaesser, and Gledhill’s discourses on melodrama to support my definition. By the end of this essay, I will give a brief explanation on why the melodramatic film as the contemporary drama is important and universally understood. In order for a film to be considered to be a melodrama it has to have a presence of verisimilitude. In other words, a melodramatic film has to mimic real life. According to Elsaesser’s essay, he says that, â€Å"even if the situations and sentiments defied all categories of verisimilitude and were totally unlike anything in real life, the structure had a truth and a life of its own, which artists could make part of their material (37... ...ealizes the loss Pita is going to have. By adulthood, one is familiar with extreme sadness and true suffering. Most adults know the feeling of never being able to say you love someone because they have passed on. Or, losing your favorite toy. Even if you haven’t gone through such life changing events, we have all experienced the separation from our mother’s womb into the world. Our first cry is our first trauma that is implanted into our psyche. That’s why in Melodramatic films are solemnly those of great pathos that make the spectator cry because they familiarizes with the pain (even a five year old can understand), and there are cries of joy at the end for the purpose of catharsis which relieves of trauma of separation. (Why is crying therapeutic? How does it relieve this trauma? Does it cause us to confront the anxiety of separation you are referring to?)
