Why is Sir Isaac Newton Essay Example for Free

Why is Sir Isaac Newton Essay Why pick a scientist over someone who has contributed to any other field of endeavour? Look at the evidence: here is a person who discovered the universal law of why what goes up must come down, the explanation of the colours of a rainbow; and a method of calculation with applications in far reaching areas that affect our lives today. Newton is best known for formulating a universal law of gravitation, however it is unlikely that his ideas stemmed solely from the well-known story of an apple falling on his head whilst sat under a tree. His mathematical researches into planetary motion drew him to the conclusion that that the force of attraction that held planets in their orbits, and the Moon in its orbit around Earth, varied inversely with the square of their distance from the sun. In other words, the nearer you are to a planet the greater its force of gravitational pull. This was his fundamental law of gravitation. He discovered that the force of gravity affected all objects in the universe. His laws of motion can be summarised as follows: 1) Everything preserves its motion in a straight line unless its deflected from that course by a force. 2) The rate at which a body travels is in proportion to the force applied on it. 3) To every action there is an opposite and equal reaction These laws held true for many years and it was only until Einstein, in the twentieth century, proposed his theory of relativity that we were to have a more accurate picture of how the universe behaves. Newton is said to have invented the Calculus. The calculus, most simply put, is a way of finding the area under a curve drawn on a graph and the gradients of tangents drawn at any point on that curve. Why is this useful? Well, this allows us to find out rates, areas and volumes by what is known as differentiation and integration. For instance, if you wanted to find out how quickly your reconditioned MK1 Ford Cortina with go-faster stripes accelerated to 0-60 mph in, you could set up an experiment to plot the distance travelled by the car accelerating from a stand-still to its top speed against time. If you used differentiation on a corresponding curve drawn on a graph, you could find the speed of the car at any given time. Furthermore, if you used differentiation again, you could determine its acceleration. Alternatively, you could set up an experiment to measure the cars speed against time, if you were to find the area under the resultant curve using integration, you would be able to establish the distance travelled. Apart from measuring the performance of tasteful 70s automobiles, the calculus can be applied to more significant things like ascertaining reaction rates of chemicals, or discovering where the greatest stresses and strains are likely to be caused on a bridge. In the field of optics, Newton discovered that if a beam of sunlight were passed through a glass prism it would reveal rays forming a spectrum of colours, like that of a rainbow. He concluded that white light was composed of many different types of rays which when refracted at slightly different angles would produce a different spectral colour. He made this observation when using a refracting telescope and witnessed that the lenses were not clear but had an abnormal colour. It also led him to invent a reflecting telescope that did not display this aberration. But what of Newtons character: He typified the mathematical genius. He was obsessive by nature; at times toiling sixteen-hour days on work that would change the course of history. Anecdotes abound about his absent-mindedness, especially when entertaining friends (which he did rarely), where he would excuse himself to get more wine or run a similar errand, and would not return for some time because he had been busily working on some mathematical problem that had been troubling him, oblivious of his guests. He is someone who overcame adversity, probably being plagued with depression for most of his life, which resulted in him suffering two mental breakdowns. Despite his achievements he remained a modest man saying once: If I have seen farther than others, it is because I was standing on the shoulders of giants. During his lifetime he never married, although one could argue that he was married to his work. He summed up his scientific endeavour and cosmic curiosity when he innocently remarked. I know not what I appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell, whilst the great ocean of truth lay all undiscovered before me. Greatness but touched with humility, a lifetimes work that has had an enormous impact on the development of mankind and a single-minded pursuit to uncover the secrets of the universe: Surely Newton is the greatest Briton of all time.

Essay --

The fictional short story by Kurt Vonnegut entitled Harrison Bergeron takes place in a dystopian future. Vonnegut chooses to make the story a satire in order to raise questions concerning how desirable social equality is within this world and how far society will go to achieve it. Like many dystopian, bleak, futuristic worlds, Vonnegut presents very clear aspects of how society is influenced by propaganda and the extent to how powerful a tool propaganda can be. After reading and analyzing this story, I will attempt to explain how Kurt Vonnegut’s life could have influenced his position on propaganda found within this short story. Furthermore, these elements will be matched to those common propaganda strategies discussed in this class and relate how this may impact any modern society. Vonnegut's experience as a soldier and prisoner of war had a defiant influence on his work. He served as a private and was captured during the Battle of the Bulge in World War II. He was chosen as a leader of the POWs captured because he spoke a little German. After telling the German guards "what [he] was going to do to them when the Russians came,† he was beaten and had his position as leader taken away. Vonnegut was one of the lucky ones to survive an attack in a meat locker used by the Germans as a detention facility. Vonnegut said that the aftermath of the attack was "utter destruction" and "carnage unfathomable." This experience was the inspiration and central theme for many of his other books including Harrison Bergeron. The Germans put the surviving POWs to work, breaking into basements and bomb shelters to gather bodies for mass burial, while German civilians cursed and threw rocks at them. Harrison Bergeron is what seems to be a negative po... ...y to show just how absurd a life living with handicaps can be. The handicap system is a metaphor that tries to bash the ideas of communism that he undoubtedly incorporated from history using Hitler’s Germany and Cold War Russia as examples of how this system is flawed. The satire is further enforced by the elements of propaganda that he uses in the story. The television is the medium in which all people in society use to get their information. It is a powerful tool and Vonnegut has the entire story’s setting be only around the television to show just how much people rely on it. He also shows how propaganda has conditioned people to follow what the State wants them to do by appealing to the people’s logic that no one person should be than another. A good idea in principle, but in action, it causes a lot of harm and only benefits the State or the people in control.

In Praise of the F Word Essay

In Mary Sherry’s essay, â€Å"In Praise of the F Word,† the author encourages all parents and teachers to use failure as a form of encouragement. Sherry would like for them to use it as a way to motivate students to do better and want more when it comes to their education. What Sherry believes in is that the threat of flunking is a â€Å"positive teaching tool† (566). In Praise of the F Word by Mary Sherry Summary Mary Sherry in praise of the F  word uses a variety of examples to support her claim. The author’s main source of evidence used to support her claim was personal experience. Sherry shares with us her son’s senior year high school experience. He was not putting in the necessary effort needed in class and his English teacher, Mrs. Stifter was not willing to tolerate it. She then said to Sherry that she would flunk her son. Without having seen this type of approach before Sherry was flustered. Not once before had her son been threatened by a teacher like that, but she managed to agree with her approach in the end. Her son realizing he would fail and not graduate, made English class a priority and passed with an A grade (Sherry 565). One of the many night students that Sherry teaches said, â€Å"I was a good kid and didn’t cause any trouble, so they just passed me along even though I didn’t read well and couldn’t write,† this example shows that instead of the teacher using a method that gives her the power she needs, students do as they please without much effort. Sherry’s son was the type to get away with many things until now faced with the fear of failure. The greatest strength in Mary Sherry’s argument is the involvement of her night time students. I believe the things some of them had to say about their personal education experiences helped me fully understand and support Sherry’s claim. I have also personally heard people question their reasons for receiving their high school diploma, I have heard people say they never received a passing grade on an assignment but had a great relationship with the instructor, so they passed the course. The things that some of the students stated and experienced were examples of what I saw in my high school. I enjoyed the way the essay flowed, not a thing seemed to be randomly inserted and was easy enough to interpret. Lastly, I liked the way  Mary Sherry included her personal experience with her son, it was a way of demonstrating that situations where students are accustomed to simply sailing by are happening everywhere. The greatest weakness in the argument is the lack of a possible outside source. I would have liked to see numbers or a study conducted to see how many students have experienced situations where they didn’t have to do much to earn their diploma. I also think it would have been great to include other teachers’ perspectives on this subject and if whether or not they think it is a good idea to praise the F word. I think research could have made the essay a lot more reliable and persuade the readers even more. Overall, Mary Sherry presents her audience with a compelling and convincing argument. I believe she did an excellent job on persuading readers to agree to this form of teaching to help improve education by stating that, â€Å"students don’t put school first unless they perceive something is at stake in the end. They‘d rather be sailing† (Sherry 566). Sherry did a good job on repeating the need for having a fear of failure and having the threat of flunking as a positive form of teaching for students in a way to try and convince her readers.

The American Youth Soccer Organization - 898 Words

Many years ago I volunteered with AYSO – American Youth Soccer Organization. During my few years there as coach, age director and referee I became associated with the Volunteer Protection Act as well as the Child Protection Act. So when time came for our church in Washington to create a children’s ministry program, I was able to help the church in implementing these Acts into its policies. We never called the news and spouted off that we were the first to do such as another church attempted to do, because we did these things to protect the Children and our volunteers. The other church that had done similar did so just to attract new member into its ranks. Another problem with today’s church is its negligent selection of its staff and volunteers. At the very least the church should run all prospective workers through the National Sex Offenders Public Website. Yet I feel that isn’t enough either, as the Sex Offenders database only keeps records of sex-relate d offenses. Churches should do random background check yearly on all of its volunteers. Yet as most churches that I have come in contact with would say, â€Å"We are low on volunteers and we don’t want to scare prospective volunteers away!† What good is a volunteer if he is a criminal or sex offender? Are we going to be like the Catholic Church and secretly move our sex offenders around like some kind of shell game? Find the Church find the offender!
