Michael Faraday Essay Example for Free

Michael Faraday Essay Born September 22, 1791, he grew up in Newington Butts after his family had moved there from Yorkshire in order to try and make a living. His father, a blacksmith, fell ill and could not earn much money. This meant Michael left school at 13 and knew very little about maths, and almost nothing about science. When he went to work as a bookbinder he got his big chance. While binding books at the shop he would read the contents. Since scientists wrote their findings in books and discussed them, this was a great way to learn about science, and how the world works. Later, due to good luck he was working for a man by the name of Humphry Davy. Davy worked at the royal institution, doing demonstrations and lectures. Faraday belonged to a religious group called the sandemanians, which believed in a literal understanding of the bible. This meant he could not hoard or save money. When he married his wife he received financial help from the royal institution. Faraday offered many contributions to the world of science including electrolysis; generators, magnetic fields and electromagnetism, but his greatest contribution to the world would definitely be the electric motor. Faradays greatest discovery, the electric motor has affected greatly the world we live in and how we live in it. Faraday found that if you took a magnet it would rotate around a wire so long as the wire had current going through it. Through this experiment, Faraday had successfully performed the first conversion of electrical energy (in the wire) into mechanical energy (the moving magnet). He also found that if you fixed the magnet in place and let the wire move, the wire would rotate around the magnet. By studying these experiments, Faraday believed that when current is passed through a wire, a circular magnetic current circles the wire. This was the predecessor of the electric motor. Due to Faradays experiments we can use electric blenders, CD players and much much more. By discovering the circular fields around a wire induced with current, Faraday has greatly contributed to the world of physics. With further research of these circular currents around a wire, Faraday took an iron ring and wrapped a length of insulated wire around one side of it, and then wrapped a second length of insulated wire around the other side of the ring. He anticipated that if he passed a current through the first wire, it would establish a magnetic field in the ring, which would then induce current in the second insulated wire. When he first performed the experiment he believed it was a failure, as it appeared no current was induced in the second wire. But then he made an observation critical to the experiment. He observed that as he turned the current in the first wire on and off, current would be induced in the second wire. Instead of current in the first wire inducing current in the second, he realised that change in current of the first wire induced current in the second. To test his new theory, Faraday took a magnet and moved it in and out of a coil of wire. When the magnet was moving into the wire, the needle on the galvanometer would move one way. And when the magnet was moving out of the coil, the needle would move the opposite way. Next he set up a copper disc between two poles of a magnet. This time when the disc was spun a constant current would be induced. Faraday had created the first dynamo or electric generator. A device, which produces electrical energy from mechanical energy. Commonly used as bike-light generators. Faraday also enjoyed the science of chemistry. He did demonstrations at the royal institute where he would show demonstrations of pyrotechnics, big flashes, physical reactions, and chemical reactions, among other things. By combining his enjoyment of chemistry with his knowledge of physics, Faraday made some very important discoveries in electrolysis, which are still relevant today. Faraday revolutionised knowledge of electrolysis by introducing new words. He replaced the previously used pole with electrode to describe the object dangled into a solution. He described anode as the electrode where negatively charged gases attract, cathode as the electrode, which attracts positively charged chemicals, electrolyte as anything released at either electrode, anions as electrolytes that collect at the anode, and cations as electrolytes that are drawn to the cathode. All these terms are commonly used in electrolysis today, a real test of how good a word is, is the test of time. Probably one of Faradays most famous inventions is the miners safety lamp. During the early 1800s there was a large demand for coal, mine shafts were being used more. This posed a threat as methane collected in the mins. And because the mines were underground the miners had to have lamps. The threat came when the lamps lit the methane, which would light up the whole shaft. Humphry Davy and Michael Faraday, who was working for him at the time, solved this problem with the safety lamps. The safety lamps comprised of a long metal mesh cylinder with a solid, hollow base and a hook at the top, some had lenses to focus the dim light. They were different to normal mining lamps because they did not light the methane the mines produced. This was a safer option for the minors and within a short while they were being used in many mine shafts. Michael Faraday probably wouldnt have been able to imaging how greatly his inventions and discoveries have affected the world. Without Faradays research on magnetic fields we would not have use of the electric motor. Without his simple generator we would not have the use of dynamos or generators. And without his induction ring we would not be able to use transformers. The first person to properly harness the power of magnetic fields. From humble beginnings, with no proper maths or science tutoring, Michael Faraday, by perseverance, made his way up in the world to become one of the most influential people of all time. Without doubt, Michael Faraday was a great man. Died august 25, 1867; Michael Faraday had left the world leaving a great contribution behind him.

April Greiman is a contemporary designer who is recognized all across the world. Through her life she is known as the first designer to use computer technology. Her work is signature for her use of different materials, texture, and color. She has also inspired many people, and has been inspired by many professors and artist in her lifetime. She continues today to impress people with her knowledge of graphics, architecture, and environment. April Grieman was born in New York City in 1948. She studied art in Switzerland at Basel School of Design. She then studied at the Kansas City Art Institute. After graduating, she moved back to New York City to work as a freelance artist until 1976. This same year, she moved to Los Angeles, California, where she opened â€Å"Made in Space, Inc.† This became a well-known graphic design studio. In 1980, April Greiman was among the very first graphic designers to fully realize the design potential in the Macintosh Apple computer. She also picked up on Quantel Painbox digital technology. She is one of the most influential graphic designers using the digital media. In 1982, Greiman became the head of the design department at the California Institute of the Arts. In the 1990’s, she wrote and published a book called â€Å"Hybrid Imagery: The Fusion of Technology and Graphic Design.† April Greiman has worked as a designer for the MAK Center for Arts and Architecture in L os Angeles. Since then, April continues to work today for companies such as Espirit, Benetton, Sears, and AOL/ Time- Warner, Microsoft, the US Postal Services, and the architects Frank O. Gehry, RoTo Architects, and others. April Greiman has received numerous awards and distinctions for her work. April works at the border some of the discipli... ...itional photographic images and cutting- edge digital images, including a life-sized self-portrait. These images were various personal images with personal significance. She told her audience to â€Å"think with the heart† and reach her audience emotionally. This was one of the first major commissions that started her successful on going career. Another successful commission was the design for Cerritos Center for the Performing Arts as seen in Figure 2. This was commissioned in 1993 in Southern California. In this project, she worked closely with RoTo Architects. German had been sought- after for her expertise in color, surfaces and materials. She is known for this piece for the materials and color applied to the buildings interiors, exteriors, and campus. With this building she included the design of exterior tiles and other architectural elements and printed pieces.

School Policy – Behaviour

â€Å"Research evidence suggests that pupils' behaviour can be influenced by all the major features and processes of a school. These include the quality of its leadership, classroom management, behaviour policy, curriculum, pastoral care, buildings and physical environment, organisation and timetable and relationships with parents. † (Elton Report, DES, 1989) The secondary education issue I have chosen to focus on for this presentation is Whole School Behaviour Policies and how such policies can influence the teaching and learning experiences in school through the use of sanctions and rewards.I chose this area to focus on because, as a student teacher on a teaching placement, behaviour in schools is one of my biggest concerns and also because, according to the Elton Report and other literature I have read, it appears that this is a major area of concern throughout secondary schools in the UK. The Elton Report, a national enquiry into discipline in schools, was established by t he Secretary of State for Education and Science in March 1989 in response to concern about the problems facing the teaching profession.Their task was to â€Å"recommend action to the government, local authorities, voluntary bodies, governors, headteachers, teachers and parents aimed at improving behaviour in schools for effective teaching and learning to take place†. (Elton Report, DES, 1989) The Elton Report has formed the basis of much of the current legislation on school behavioural policies and offers guidance for schools in drawing up their own behaviour policies.The main findings and recommendations of the Elton Report can be summarised in the following points (Teachernet, 2008): †¢School’s should adopt a ‘whole-school’ approach to their behaviour policies and the teachers’ approach should be one of consistency and fairness †¢Schools should have a clear vision for managing behaviour through establishing clear rules and boundaries, wi th emphasis on the positive. †¢All must adhere to policy principles, and teachers should model behaviour and interactions in a positive and supportive way. Boundaries should be made clear and sanctions should be in place, but the emphasis is on praise and rewarding good behaviour. †¢All staff should recognise that the quality of teaching and learning has a significant impact on pupils’ behaviour â€Å"A school's central purpose is that children should learn. Good behaviour makes effective teaching and learning possible. Bad behaviour disrupts these processes. † (Elton Report, DES, 1989) In September 2003, the government’s Department for Children, Schools and Families (DCSF) launched the Behaviour and Attendance strand of the Key Stage 3 Strategy.This programme aims to provide advice, support and training for all secondary schools in England to promote positive behaviour and tackle issues of low-level disruption. It recommends that senior leadership tea ms in schools will carry out audits of behaviour and attendance and, from these, will establish priorities for the whole school. They will then plan actions to further improve their policy and practice and will draw up training plans for their staff. (Behaviour4learning, 2008) At my year one placement school I witnessed these recommendations put into practise in the classroom through the implementation of the school’s Behaviour Policy.The placement school is a mixed comprehensive school in the London borough of Tower Hamlets. The head teacher’s perception of the school’s catchment area is that it is a predominantly working class area of London with high levels of poverty and unemployment. According to the school’s latest Ofsted inspection report the number of pupils who are registered SEN (Special Educational Needs) is above the national average. Although not all special needs are connected to behaviour, it is largely acknowledged that if a child finds le arning very difficult it is possible that incidents of poor behaviour can occur. Cowley, 2006) The school has a behaviour policy in place and, by adhering to it, aims to promote a â€Å"positive learning and teaching community for staff and pupils. † (Swanlea School Behaviour Policy) The main aims, as summarised in the policy, are: †¢To ensure that behaviour is a whole school responsibility †¢To ensure that rewards and sanctions procedures are applied fairly and consistently †¢To foster compassion and tolerance, celebrate diversity and develop a sense of citizenship and care for the whole community and environment †¢To enable all pupils, irrespective of race, class, gender and ability, to achieve their personal best. Swanlea School Behaviour Policy) The policy also sets out the rights of staff and students, which are summarised as: †¢Every student has the right to learn at his or her optimum rate, without being hindered by others †¢Every student has the right to live each day in school without fear. Bullying, threatening behaviour, racial or sexual harassment and damage to property will not be tolerated. †¢All staff have the right to go about their work without being hampered (Swanlea School Behaviour Policy)This reflects a clear alignment with research by Cowley (2006) who states that: â€Å"Different types of school have very different and specific behavioural problems, and ideally the whole-school behaviour policy should be linked closely to the particular difficulties your school faces. † (Cowley, 2006, p172) The school’s behaviour policy is clearly in place to create a positive environment for pupils but it is also there for the benefit of teachers and staff to create a positive working environment and enable the teacher to effectively teach without disturbance. It’s important to keep in mind that the reason we need to manage behaviour at all is so that we can actually get on with teaching. â €  (Cowley, 2006, p96) The policy was established by the head teacher, deputies and heads of department together with the behaviour support team. It is managed by the deputy head teacher and is reviewed each term, through consultations with heads of department and the behaviour support team, at designated ‘Behavioural Policy Review’ meetings.These meeting allow for changes to be made if the policy appears to be ineffective and, for example, if incidents of bad behaviour have increased. In order to check the effectiveness of the policy, the deputy head teacher analyses data, in the form of exclusion rates, details of incidents of bullying and racist abuse and the use of sanctions and rewards. All of the school’s staff, including teachers and support staff, are responsible for ensuring that the behaviour policy and procedures are followed and applied.This ‘guidance framework’ has made it easier for staff to respond to incidents of bad and good behav iour consistently and fairly and for all students to be made aware of the policy. As recommended in research by Rogers (2006): â€Å"When schools have a common framework for classroom behaviour agreements, each successive year group becomes increasingly conscious of ‘the way we do things here’. â€Å"This enables some sense of common understandings and expectations about appropriate and fair behaviour and also some reasonable consistency in behaviour management by adults across the school. (Rogers, 2006, p46) The behaviour policy states that all staff are expected to model the high standards of behaviour and punctuality expected of pupils. Form tutors are also expected to support and encourage individual pupils through praise, positive reinforcement and contact with parents. The policy also advises that form teachers are directly involved with low level behaviour issues, such as addressing school uniform issues. The school believes that maintaining a level of consiste ncy across all staff and department, with regards to the behaviour policy, ensures that all pupils are aware of its contents.This is in line with Rogers’ (1995) and Cowley’s (2006) findings, who say that a whole-school behaviour policy is effective when it:- †¢Is created in conjunction with all the staff †¢undergoes a continuous process of change †¢is consistently applied All pupils at the school carry a travelling diary to lessons in which homework and behavioural issues such as lateness are monitored and recorded. The ‘travelling diary’ contains a summary of the school’s behaviour policy and expectations – further ensuring that the students are aware of the policy contents.Assemblies on the theme of respect and behaviour are also delivered to the pupils on a regular basis. â€Å"The behaviour policy is well constructed and understood by most students and applied evenly by all staff. † (Ofsted, 2007) The school has in p lace a system of sanctions and rewards to deal with negative and positive behaviour respectively. Depending on the severity of the negative behaviour in the school, the sanctions range from a verbal ‘telling off’ to the child being placed in the school’s isolation unit. Sanctions are there to offer corrective measures to indicate to the perpetrator that the displayed behaviour is not acceptable and provide and opportunity for the individual to redeem him/her self. † (Swanlea School Behaviour Policy) The behaviour policy states that the school aims to support a positive learning environment for students through the use of rewards for good behaviour. This ranges from praise from the teacher to formal awards and prizes at the school’s annual awards ceremony and during assemblies. This in reflected by Cowley (2006) who says: Using rewards is one of the most effective ways of getting better behaviour†¦. This will help you maintain a positive focus an d atmosphere in your classroom. † (Cowley, 2006, p81) However, it is challenged by Kyriacou (1998) who argues that it is ‘effective teaching’ not rewards that create better behaviour. â€Å"The most important point to bear in mind in considering discipline is that creating the necessary order is more to do with the skills involved in effective teaching in general than it is to do with how you deal with pupil misbehaviour itself. (Kyriacou, 1998, p79) To sum up, from classroom observations at my placement school I frequently observed incidents of students’ bad behaviour and how these incidents were dealt with in the design and technology department. It was apparent that the design and technology department, like the rest of the school, is closely following the guidance in the behaviour policy and is very efficient at dealing with bad behaviour. This appears to have a positive impact on the school in that it creates a safe environment for the pupils.However, on a daily basis I observed poorly behaved children being given break time detentions and several children receiving the ‘ultimate sanction’ of the isolation unit. While this appears to be effective in that it creates an ordered classroom environment for teaching and learning to take place, I frequently observed the well behaved pupils going un-noticed in the school’s efforts to stamp out bad behaviour. .â€Å"We can get trapped into giving lots of rewards to our tricky students, to keep them onside and get them to co-operate.But don’t overlook those children who work hard all the time – they deserve to receive recognition for their efforts as well. † (Cowley, 2006, p83) This suggests that their behaviour policy is not working as effectively as it could and that a solution could be to have, embedded in the behaviour policy, a system of rewarding good behaviour and recognising hard working children, as well as responding to the studentsâ€⠄¢ bad behaviour.

Definition and Examples of Exclusive We

In English grammar, exclusive we is the use of first-person plural pronouns (we, us, our, ours, ourselves) to refer only to the speaker or writer and his or her associates, not to the person(s) addressed. For example, Dont call us; well call you. In contrast to inclusive we, exclusive we does not include the audience or the reader. Often (but not always), exclusive we occurs when the first-person plural is used in the company of a second-person pronoun (you, yours, yourself, yourselves).   The term clusivity was recently coined to denote the phenomenon of inclusive-exclusive distinction (Elena Filimonova, Clusivity, 2005). Examples and Observations: Im especially fond of the inclusive and exclusive we. Thats a distinction between Were going to the movies. Are you ready yet? and Were going to the movies. See you later!—in other words, between being invited to the party and being a third wheel.Its particularly useful when you want to switch back and forth between the two: Im writing to you on behalf of my colleagues. We (exclusive) are wondering if youd be interested in collaborating with us (exclusive). We (inclusive) could accomplish great things together! We (exclusive) hope to hear from you soon about the future of us (inclusive)!(Gretchen McCulloch, Four Features From Other Languages That We Wish English Had. Slate, October 24, 2014)Defenders of Earth: we have come for your natural resources to rebuild our damaged planet. When we have transported all we need, we will leave your world in peace. For such peace to exist, you must immediately exile the Autobot rebels you have harbored. Non-negotiable! Renounce the rebels. We await your reply.(Leonard Nimoy as the voice of Sentinel Prime in the movie Transformers: Dark of the Moon, 2011)All we ask is that you make use of these ships. Sail them back to Westeros where you belong, and leave us to conduct our affairs in peace.(George Georgiou as Razdal mo Eraz in The Bear and the Maiden Fair. Game of Thrones, 2013 Khrushchev: Many things youve shown us are interesting, but they are not needed in life. They have no useful purpose. They are merely gadgets. We have a saying: if you have bedbugs you have to catch one and pour boiling water into the ear.Nixon: We have another saying. This is, that the way to kill a fly is to make it drink whiskey. But we have better use for whiskey.(Soviet premier Nikita Khrushchev and American president Richard Nixon in the Kitchen Debate, July 24, 1959. Richard Nixon: Speeches, Writings, Documents, ed. by Rick Perlstein. Princeton University Press, 2008Well, all along, I guess, I thought we didnt have much of a life. You kno w, I felt we--well, not you, but the rest of us--were rejects. In fact, they actually had me believing that I was totally undeserving, and I was supposed to be missing out on even the basics.(Sky Lee, Bellydancer. Raincoast Books, 2002For the present, let us return to the experiment with the opium. We have decided that you leave off the habit of smoking from this moment.(Wilkie Collins, The Moonstone, 1868You heard Santos-Dumont talking about going to St. Louis and winning a prize? Im damned if he will, not while weve got time to build an airship of our own.What do you mean we?Why Fitz, you dont think wed leave you out? Were letting you in on the ground floor as our first investor, and youll get your share of the prize money in St. Louis.(Walter J. Boyne, Dawn Over Kitty Hawk: The Novel of the Wright Brothers. Forge, 2003) The Top-Down Approach - Exclusive we . . . excludes the reader since it suggests an us-them relationship. Its use may make a text appear authoritarian as it underlines opinions of or actions undertaken by a group external to the addressee.(Anne Barron, Public Information Messages. John Benjamins, 2012)- The exclusive we implicitly sets up a hierarchical power relation and points to the top-down approach in instituting change.(Aaron Koh, Tactical Globalization. Peter Lang, 2010) Combinations of Inclusive We and Exclusive We Biber et al. (1999: 329) assert that the meaning of the first person plural pronoun [we] is often vague: we usually refers to the speaker/writer and the addressee (inclusive we), or to the speaker/writer and some other person or persons associated with him/her (exclusive we). The intended reference can even vary in the same context. Inclusive and exclusive we can be used to create a perspective of: I the speaker you the addressee(s) in the immediate context (inclusive we) and I the speaker someone else not in the immediate context (exclusive we). . . . Understanding speaker identity is crucial to understanding context . . .. (Elaine Vaughan and Brian Clancy, Small Corpora and Pragmatics.

Springer, 2013) Grammatical Features Associated With Inclusive We and Exclusive We [A]lthough the distinction between an inclusive/exclusive  we is not morphologically marked in English, Scheibmanns (2004) analysis of conversational utterances in the first person plural has shown that different referential values of we may be signaled by the differential employment of other formal features of the utterance. More specifically, an inclusive interpretation of we was found to favor employment of present tense and modal verbs, while exclusive interpretations of we appear more frequently with past tense and fewer modal verbs.
