Engineers related with the internal combustion engine Essay Example for Free

Engineers related with the internal combustion engine Essay Rudolf Diesel resided in Paris and was born in 1858. Munich Polytechnic was the school that enhanced his capabilities. Diesel was interested at engine design. Rudolf was recognized in engine designs; Engines like the solar powered air engine was one of his recognizable inventions. He also known to as to publish articles about an engine with combustion within a cylinder; it was soon known as the internal combustion engine. In 1894, he patented his so called diesel engine. The engine invented by Diesel was known to be the first that can ignite the fuel without spark. The first operation of the engine was in 1897 and it was said to be successful. The internal combustion engine with the diesel engine was government granted rights in 1898 (National Inventors Hall of Fame). Nikolaus Otto was a resident of Holzhausen, Germany. On June 14, 1832, Otto was born in Germny. Nikolaus Otto was a drop out in the high school and after that he work as aid for a grocery store. He became a person of hard work; he acquired many works. He works as clerk and traveling salesman in different institution. He collected data and soon find out about the gas engine that was invented by Etienne Lenoir. Unexpectedly, the Lenoir engine came to failure and then was not recognized. Lenoir engine has a troublesome ignition system. From the failure, Otto thinks about the use of liquid fuel. He soon devised a carburetor to help the work of Lenoir have developments. The two stroke engine was patented by Otto and his partner in 1861. The two-stroke invented ran on a gas. With the recognition acquired in the two stroke engine, he came up to the idea of making the four-stroke engine. It was made as substitution for steam engine (Pagewise). Jean-Joseph-Etienne Lenoir, French engineer and inventor, who came to developed the internal combustion engine. He was also known to make white enamel 1847, an electric brake and also develop an automatic telegraph. Before Lenoir work came to recognition, many other works of internal combustion were claimed by unreliable inventors. His model of combustion engine was very practical that it made them become real. The engine being developed by Lenoir was made up of cylinder with storage battery. Slide valves were provided in the two-stroke cycle and this cycle was fuelled by coal gas. Powering small items of machinery was his engine used for. He patented his internal combustion engine in 1860 that used kerosene as fuel. After two years of development, his engine makes a record of having a speed of 6. 4 km per hour (Auuuu. com. ). Impact Through the years of development and innovation of internal combustion engine, it was said to be show significance and impact to the world. Especially with industries and automobiles and cars, internal combustion engines were set to be as important in all terms. In the 1900’s, western countries were utilizing this kind of engine produce a large amount of automobiles. Internal combustion engine was adapted for use in by ever sea, land and air transportation. With sea transportation, much numbers of ships or any sea transport means used diesel engines. In this way they are providing easiness in the transportation of people as wee as goods thru and from port. Trade becomes more rapid and less expensive. Airplanes also have been thankful to the development of gasoline engine. Before the development of internal combustion engine, flights have been not good. But thru the development of these internal combustion engines, it has played an important role in private, commercial and military aviation. In farming and food production, internal combustion engine was said to be also important. Abundance of food and were seen as tractors and other farming equipments were powered by diesel engines. There is a significant improvement that was seen; there is an increase in the amount of land farmed. This means that it was not only the farm owners who will be benefiting but also the consumers. This is because the costs of farm goods will decrease. And not only that, internal combustion it is also seen to be producing much more amount of goods. On the environmental aspect, internal combustion engine was not bad for the environment. Actually, it was really significant. Internal combustion engines were being operated thru burning forms of hydrocarbons as it also discharges exhaust gases. These petroleum based hydrocarbons were to produce carbon dioxide, carbon monoxide and water also. Other impact in the environment is very great because the process of extraction of provides some invariably great results (Auuuu. com). Internal combustion Engine (Overall Aspect and Summary) The internal combustion engine a prime mover, that means it utilizes some form of energy to shift objects. In the mid of the nineteenth century, the first reliable internal combustion engines exist and were industrialized. It was also almost instantly put to use for transportation. The development and improvement of the internal combustion engine helped to people in was that it helps them to do toughest manual work. There were several engineers and inventors who supposed to give try to make the internal combustion engine. But not all had been successful for the development. Here are the names of the famous engineers and inventors that were given recognition for the development of these engines. One is Lenoir, made the first possibility of the internal engine. Otto and Diesel was also seen to be accomplished for the successful of the internal combustion engine. Another is Daimler and Maybach who gave it a try with bicycle and motorcycle. They also produced a car making it have the four-speed gearbox. Karl Benz also was known due to his production of gasoline car. There are even more inventors and engineers who have shared their ideas to develop or at least improve the internal combustion engine. The impact of internal combustion engine was really significant for the different modes of transportation and industrial countries. They were given the easiness of providing fast service to their consumers. The transport modes were speedy service. The industrial parts were to produce their products in a fast pace. At home, it was also significant because all equipments like chainsaws and the like were also powered by internal combustion engine. As well in farms, the production was made fast because of the engine that helps them farmed much amount of lands. The economic also was being benefited in term of providing carbon monoxide and dioxide and water which is essential for the everyday life. These were really signifies that the development of internal combustion engine was made for the good purpose for the human and the world. It does not only secure the impacts on the industrialized nation but also concerns with the whole community. Conclusion Internal combustion engine was only one of the essential development and innovation in the world of technology. Since great inventors are coming up with ideas that will provide good impacts on the community as well with the technology itself. The engineers and inventors are making sure that every innovative idea within the world of technology, the significant and the development must come together as these ideas were to be brought out in the community. Internal combustion engines are most generally used for movable force systems. Home, industries, transport companies and farmers are the common groups that were being benefited by these innovations of the internal combustion engines. Electric generators and industry were also utilizing these engines. These innovations had greatly affects essentially for the fast paced of works in any of these groups.

The Teachings of Mathematics Education in America Essay -- miscellaneo

The Teachings of Mathematics Education in America Math educators in the United States should stress the understanding of the learners and teach them to process certain understanding to succeed in mathematics. The connection between math understanding and the reading of math problems should be raised in smaller grade levels so students have a better understand of math at younger ages. Yet it is not all the students’ part in learning the math, but also the educators’ part to teach the subject in an understanding manner using the curriculum and proper textbook. The rankings of mathematics in the United States are just barely above average compared to the world standards, and the preliminary studies show that the twelfth grade level tests are even lower and politics has to be blamed for this (Math and Learning). â€Å"As teacher-educators and lifelong mathematics enthusiasts, we think that America’s problems with math are not new news; they predate both the No Child Left Behind Act and the reform-math movement. To us, the story here is less about test scores and more about the nation’s attitudes toward math. Simply put, America is math-phobic—to an extent that profoundly influences our country’s policies, teaching practices, and, ultimately, the performance of our students.† (ERIC) The National Council of Teachers of Mathematics (NCTM) want to emphasis the basic skills taught in math classes as per their standards made in 2000. The old standards, made in the 1990’s, stressed importance on new ideas, and integrated technology use to solve complex equations. Ms. Lappan, the president of NCTM said, "That became, in some places and for some teachers, the goal. They missed the main goal: that children become highly skilled in using mathematics; We've tried to be very clear [in the revised standards] that mathematics is the goal.† The proposals of the 1990 standards and the 1998 needing revisions said the same: â€Å"Mathematics teachers need to reach all children by offering a variety of instructional strategies that encourage students to learn the concepts that lie under the algorithms they are learning; The changes, however, are unlikely to satisfy critics who find fault with the 1989 standards themselves, not just the way teachers and policymakers have implemented them. And they may also confuse and frustrate educators who have radically changed the way they teach... ...e poor teaching in the country. â€Å"The Third International Mathematics and Science Study warn unequivocally: United States students need to work toward a better, deeper understanding of mathematics--the "how" and "why" behind the equations. Without a clear, consistent vision for teaching math, there is little chance for any of our children to ever meet these standards. And this vision must start with the people whose job it is to impart knowledge to them: the teachers (ERIC).† â€Å"Political leaders of both parties have certainly recognized the need to address this crisis. America 2000, initiated by President Bush and adopted in somewhat different form as the Goals 2000 Act signed by President Clinton, calls for national standards in every educational discipline (Math and Learning).† The teachings of math in this country affect students in many ways such as teachers that teach math, the government that doesn’t support better funds for teaching math, the curriculum reform, and many more. Most of these things are not as visible in society yet it still occurs. The students ranking so low in the world in math is not good at all, and there needs to be something done about the matter.

Eleanor Rigby Literary Analysis Essay

In the song â€Å"Eleanor Rigby† by The Beatles, there is a lonely, sad woman who dies and is readily forgotten as she has nobody to care about her. How many people do we see out on the street that will just become â€Å"another dead body?† Eleanor Rigby really puts this into perspective that there are lonely people in this world living their lives serving others without being acknowledged. Eleanor is waiting for someone, but she is scarred in her heart by her lonely life. Sadly enough, she is an afterthought even in her death, as Father McKenzie writes her sermon in his socks, late at night. The theme of the song is that keeping the up the illusion isn’t always worth it. The literary devices demonstrating this theme are allegory, repetition, and imagery. An allegory is symbolic narrative details that can sometimes imply another meaning. There are many examples of this in the song. In the line, â€Å"Eleanor Rigby picks up the rice in the church where a wedding has been. Lives in a dream,† The Beatles display a good example of allegory. The church in the song is very symbolic for life and death for many reasons. There is a mention of a wedding in this line and in some cultures a wedding is known as the celebration of life, however in the end Eleanor Rigby dies, thus being the opposite of life, instead she represents death. This allegory relates to the theme because it shows that Eleanor Rigby lives her life working in a church, attending weddings and working to bring life and happiness to others. She is living what everybody else considers the dream, but in reality she is a sad, lonely person. She keeps up the illusion of being happy and everyone believes her, however in the end she dies unremembered. Another representation of the theme is repetition. In the lines, â€Å"All the lonely people, where do they all come from? All the lonely people, where do they all belong? Ah, look at all the lonely people. Ah, look at all the lonely people† The Beatles use the repetition of â€Å"lonely† to drive in the main message of the song. Saying that Eleanor Rigby is living the dream can be deceiving to listeners but by the repetition of â€Å"lonely† they make it clear that underneath the faà §ade of grandeur, there is a bleak undertone. This is a fantastic example of use of repetition to convey the theme because The Beatles make the whole song an illusion except for the chorus in which â€Å"lonely† is continuously repeated and in the end Eleanor Rigby dies, proving without a doubt that the illusion wasn’t worth it. One of the most prominent literary devices in the poem is imagery. The Imagery  is used to show exactly how much of an illusion Eleanor is living. In the line, â€Å"Waits at the window, wearing the face that she keeps in a jar by the door† It is very easy to imagine somebody literally keeping a head or face in some type of liquid in a jar to be put on when necessary. This line is actually not meant to be taken quite so literally. This face in the jar is probably the face that she puts on to look beautiful, the jar being the makeup jar from which the face comes. She disguises her sadness and her longing with the face by her window. She doesn’t literally put on a mask or someone else’s face, but she puts on a face to fit society. This example of imagery fits the theme because Eleanor Rigby wears face so that no one can see the loneliness and emptiness that she feels. It is a false impression that she is giving to everyone that she sees, it is nothing but an illusion. As Eleanor Rigby dies at the end of the song, it is clear that the illusion of happiness wasn’t worth keeping since nobody even remembered her. The very apparent theme in the song is loneliness. Eleanor Rigby was very lonely although she never let on and thinking she was well off and happy, nobody else ever thought to pity her or pay her attention. In the song, Father McKenzie wipes the dirt from burying Eleanor off of his hands. Wiping the dirt from your hands is a phrase often used to illustrate that you are going to get rid of something and forget about it. It is clear that the minister just wants to forget about Eleanor and take care of his own problems, thinking she lived a good life, he is impartial. Through the use of allegory, repetition, and imagery The Beatles paint a mesmerizing tale of the false life a woman lives to keep up the illusion of happiness, all for naught.

Holocaust Research Paper - 3287 Words

The Holocaust was one of the twentieth centurys greatest tragedies that were made possible by anti-Semitism, the indifference of other nations, isolationism politics, and outright fear. Mrs. Arana/ Period 3 Miranda Ruiz 5/16/11 The road to the creation of the Holocaust started with one man. Adolf Hitler. Although thousands of people agreed with anti-Semitism at the time he was the one who started to take his thoughts into actions. After World War 1, German was in great poverty, unemployment and starvation. And the one group of people to blame were the Jewish people. Christians have been angry at the Jewish people ever since they killed Christ, and Adolf Hitler thought of this idea to eliminate the Jewish people once and for all.†¦show more content†¦And they burned holy books as well as forcing the Jewish people to sit through long sermons promising hell to anyone who died Jewish. But, the difference between the anti-Jewish behavior of the Church and the anti-Semitic behavior of the Nazi’s was that the Church wished to destroy Judaism by converting the Jewish people, Hitler wanted to destroy the Jews themselves (45-47). This was the first recorded anti-Jewish behavior. After the murder of Ch rist, all Christians and Catholics hated the Jewish people. But they had reason and every generation the Churches have decided of way after way of punishing the Jewish people. But Germany has had a long history of anti-Semitism. Consistent with Rossel, Germany has had a past of anti-Semitism, starting in 1542 when the great German Protestant leader Martin Luther wrote a booklet called Against the Jews and Their Lies. Even earlier the Catholic Churches had taught that the Jewish people killed Crist and should therefore be hated (10). Early teachings of anti-Semitism lead to a hating of the Jewish community, but with the German’s calling themselves the â€Å"Aryan Race† and the Jewish people calling themselves the â€Å"chosen one’s† there was bound to be competition on who was superior. According to Rossel, the Treaty of Versailles demolished the spirit of Germany, this is because of all countries in Europe, and Germany’s had its pride in stability in their military strength.
