Modules on skills and materials Essay

â€Å"Well prepared teachers have a large repertoire of activities for their classes. They can organise preparation and controlled output practice; they can direct students in the acquiring of receptive skills and organise genuinely communicative activities. This repertoire of activities enables them to have varied plans and achieve an activities balance.† â€Å"The Practice of English Language Teaching† Harmer Which of the techniques outlined in this module, and elsewhere in the modules on skills and materials, would you use in order to achieve genuine communication in the classroom? This task should refer to other areas of the course. You should aim to write about 750 words. The ultimate aim of teaching English to speakers of other languages is to achieve genuine communication by limiting teacher talking time and maximising student participation. Simply standing in front of a class and telling things to the students does not guarantee they will learn them. Students need to be actively involved in the lessons. A vital step in establishing a class of active learners is classroom management. There are many techniques which can be implemented in order to achieve genuine communication within the classroom. Communication should take place the minute the class begins. Getting into the habit of ‘chatting’ to the students at the start of a lesson gives them the chance to take part in natural conversation. This can be achieved by greeting the students and allowing five minutes to go around asking what people did at the weekend, for example. This gets students speaking before they have had a chance to worry about getting involved. In order to create an open learning environment and aid the flow of communication, the furniture in the classroom should be arranged appropriately. Ideally, the furniture should be  arranged in a circle as it allows all the students to be involved and creates a sense of equality. However, if this is not possible, a semi-circle or some form of group arrangement is best. A semi-circle ensures the students are able to see any visual aids clearly and as many students as possible have eye contact with the teacher. A group arrangement allows for a huge degree of interaction and can be useful in mixed-ability classes, where groups of students can concentrate on different communication tasks according to their ability. Another great way of rousing communication is to show interest in the students by getting to know about their interests and backgrounds. This allows teachers to make conversation before and after class using personal information. How is your new cat? Is your husband feeling better? It is encouraging for the students and they are more likely to want to speak about themselves, their families, etc. Getting to know the students also allows teachers to personalise lessons and set up relevant discussions. This increases student involvement by allowing them to express opinions about their environment and personal experiences. A similar technique is to talk about current affairs or news stories. These are subjects that the students are likely to have knowledge of and will be able to discuss amongst themselves. This will encourage students to find interesting stories or anecdotes they can share with the class or to keep themselves informed so they can have meaningful input in class activities. Current newspaper and magazine articles can be cut out and used to prompt discussions. These techniques can allow the students to take control of the conversation, reducing teacher talk time and consequently further their learning. Relevant and realistic practise of language is important in spurring meaningful communication from students. Teachers should focus on elements of language and communication that are necessary for the student’s goals or are of personal interest. The types of activities utilised in a lesson can give more or less opportunities for communication. The most obvious way to get someone talking is to ask them questions, but teachers should really think about the kinds of questions they ask. Closed questions are simple direct questions that can be useful for checking understanding or reviewing language, whereas open questions do not always have a single or right answer and get the students thinking. Both types of questions are useful in the classroom and teachers should establish a good balance between  the two. Furthermore, questions should be directed to the whole class initially, rather than a named individual, as this ensures all students are alert and thinking about the answer should they be chosen to respond. Another technique to keep students focused is avoiding asking questions in a fixed order. Teachers should mix it up by darting around the classroom, keeping the students on their toes. Asking questions can be rather limiting in the degree of communication it fosters and it involves a lot of initial input by the teacher. In order to encourage genuine communication between students so they get the most out of the experience, teacher talking time needs to be limited. Group or pair-work activities are a great way to do this. They generate conversation and communication flows more naturally. Well prepared group or pair-work activities should require students to maintain communication in order to complete the task. They dramatically increase the amount of speaking time each student gets in the class and allow students to interact independently without guidance of the teacher. This promotes learner independence and more spontaneous communication. Role-plays, dialogues, sketches, etc. can be a great way to reduce anxiety about speaking. Students may be embarrassed at first, but become less self-conscious as they concentrate on the character or role they are required to carry out, thus produce more natural language. In addition, prompts, such as role cards and realia can be provided as an aid for the students to use during their performance. It is important for the teacher to continue monitoring groups during fluency tasks to ensure English is being spoken. It is imperative that the use of the mother tongue language is limited in the class. If the class are of differing nationalities, this aids communication as the students have no choice but to use English to communicate. Thus, there are many techniques that can be adopted to ensure genuine communication is achieved in every lesson. It is important for teachers to really think about all aspects of the lesson, including the introduction, seating arrangement, the delivery of activities, materials used, etc. prior to teaching in order to maximise student talk time so that each individual gains the most out of their experience within the classroom. TASK FOR SUBMISSION TO YOUR TUTOR TASK 2 You are working in an ESOL school with class sizes of 14-18. Your boss does not like your school’s current way of testing spoken English. At the moment it is tested in a one-on-one, 2 minute speaking test at the end of course with a mark from 0-10. It does not seem to be working well and takes up a whole lesson from the course. He has asked for suggestions as to how to change the system. With reference to what you have studied in this and other modules, and to your own experience and reading, make some suggestions to your boss as to how the school could assess the spoken English of the students in a more accurate and less pressurized way. You should write about 400 – 500 words to send as an email setting out your ideas. Dear ______, In light of your recent request for ideas as to how to change the current way of testing spoken English, I would like to propose the following suggestions. Rather than a one-on-one end of year speaking test, we could adopt a task approach and assess the students speaking ability in a variety of ways throughout the duration of the course. We could create tasks that require the students to use the language in ‘real-life’ communicative performances. This type of testing is advantageous as it can be conducted with more than one student at a time, reducing the amount of time dedicated to the testing. It allows the students to use their language knowledge and competence in ‘real-life’ communications with their peers. It is a more realistic and accurate measure of their abilities. Not only do these tasks test accuracy and fluency, they also test how creatively the students are able to use language and whether they are able to communicate effectively with each other . It is likely to reduce the pressure they feel about a single ‘interview’ with the teacher, particularly if they get to perform the  tasks with other students so the focus isn’t solely on them. Adopting this kind of testing approach will allow us to carry out a number of different oral tests throughout the course, assessing a variety of skills. There are a number of different tasks that could be used such as role plays, debates and presentations. Role Plays: We can give them a specific situation and roles to play that utilise the language they have learnt. Role plays can be used informally throughout the course so the students get lots of time to practice for a formal assessment. Debates: We could split the classes into groups and have each group debate an argument relating to different topics they have studied. Each group would be split into two smaller groups, one to represent each side of the argument. The students can be given time in or out of class to prepare their side of the debate. Each side could be allocated a specific time for giving their initial argument in which each student has to contribute the same amount of time. Again, debates can be used informally throughout the course to practice language, allowing students ample of practice before the formal assessment. Class Presentation: We could assign group projects for the students to carry out in or out of class. The students will have a deadline to complete the project, at the end of which they will be asked to give a group presentation. We can provide them with guidelines of what to include and what skills they will be individually tested on. Another way to test students individually that takes away the pressure of ‘performing’ in front of the class is to ask them to make a recording. In a previous school, we had students read a short story and then asked them to imagine they were one of the characters. They had to record themselves giving an account of what happened according to their {the characters} personal experience. The students were allowed time to think about what they wanted to say before making the recording. After assessment, the students listened to each other’s recordings and gave constructive feedback to their classmates. This type of assessment was carried out a number of times throughout the course, with notable improvements across the board. Although this approach is less realistic, it gives the students a chance to hear themselves speaking and pinpoint their own mistakes which they can work on in the future. I hope these suggestions are of use and we are able to implement a more successful way of testing the oral skills of the students.

Computers – Invention of the Century

The History of Computers only once in a lifetime will a new invention come about to touch every aspect of our lives. Such devices changed the way we manage, work, and live. A machine that has done all this and more now exists in nearly every business in the United States. This incredible invention is the computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years has the computer changed American management to its greatest extent. From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of management, and our lives for the better. The very earliest existence of the modern day computer's ancestor is the abacus. These date back to almost 2000 years ago (Dolotta, 1985). It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to programming rules that the user must memorize. All ordinary arithmetic operations can be performed on the abacus. This was one of the first management tools used. The next innovation in computers took place in 1694 when Blaise Pascal invented the first digital calculating machine. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father, who was a tax collector, manage the town's taxes (Beer, 1966). In the early 1800s, a mathematics professor named Charles Babbage designed an automatic calculation machine (Dolotta, 1985). It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It was programmed by and stored data on cards with holes punched in them, appropriately called punch cards. This machine was extremely useful to managers that delt with large volumes of good. With Babbage's machine, managers could more easily calculate the large numbers accumulated by inventories. The only problem was that there was only one of these machines built, thus making it difficult for all managers to use (Beer, 1966). After Babbage, people began to lose interest in computers. However, between 1850 and 1900 there were great advances in mathematics and physics that began to rekindle the interest. Many of these new advances involved complex calculations and formulas that were very time consuming for human calculation. The first major use for a computer in the U. S. was during the 1890 census. Two men, Herman Hollerith and James Powers, developed a new punched-card system that could automatically read information on cards without human (Dolotta, 1985). Since the population of the U. S. was increasing so fast, the computer was an essential tool for managers in tabulating the totals (Hazewindus,1988). These advantages were noted by commercial industries and soon led to the development of improved punch-card business-machine systems by International Business Machines, Remington-Rand, Burroughs, and other corporations (Chposky, 1988). By modern standards the punched-card machines were slow, typically processing from 50 to 250 cards per minute, with each card holding up to 80 digits. At the time, however, punched cards were an enormous step forward; they provided a means of input, output, and memory storage on a massive scale. For more than 50 years following their first use, punched-card machines did the bulk of the world's business computing (Jacobs, 1975). By the late 1930s punched-card machine techniques had become so well established and reliable that Howard Hathaway Aiken, in collaboration with engineers at IBM, undertook construction of a large automatic digital computer based on standard IBM electromechanical parts (Chposky, 1988). Aiken's machine, called the Harvard Mark I, handled 23-digit numbers and could perform all four arithmetic operations (Dolotta, 1985). Also, it had special built-in programs to handled logarithms and trigonometric functions. The Mark I was controlled from prepunched paper tape. Output was by card punch and electric typewriter. It was slow, requiring 3 to 5 seconds for a multiplication, but it was fully automatic and could complete long computations without human intervention. The outbreak of World War II produced a desperate need for computing capability, especially for the military (Dolotta, 1985). New weapons systems were produced which needed trajectory tables and other essential data. In 1942, John P. Eckert, John W. Mauchley, and their associates at the University of Pennsylvania decided to build a high-speed electronic computer to do the job. This machine became known as ENIAC, for Electrical Numerical Integrator And Calculator (Chposky, 1988). It could multiply two numbers at the rate of 300 products per second, by finding the value of each product from a multiplication table stored in its memory. ENIAC was thus about 1,000 times faster than the previous generation of computers. ENIAC used 18,000 standard vacuum tubes, occupied 1800 square feet of floor space, and used about 180,000 watts of electricity. It used punched-card input and output. The ENIAC was very difficult to program because one had to essentially re-wire it to perform whatever task he wanted the computer to do. It was efficient in handling the particular programs for which it had been designed. ENIAC is generally accepted as the first successful high-speed electronic digital computer and was used in many applications from 1946 to 1955. However, the ENIAC was not accessible to managers of businesses (Beer, 1966). Mathematician John Von Neumann was very interested in the ENIAC. In 1945 he undertook a theoretical study of computation that demonstrated that a computer could have a very simple and yet be able to execute any kind of computation effectively by means of proper programmed control without the need for any changes in hardware. Von Neumann came up with incredible ideas for methods of building and organizing practical, fast computers. These ideas, which came to be referred to as the stored-program technique, became fundamental for future generations of high-speed digital computers and were universally adopted (Dolotta, 1985). The first wave of modern programmed electronic computers to take advantage of these improvements appeared in 1947. This group included computers using random access memory, RAM, which is a memory designed to give almost constant access to any particular piece of information (Dolotta, 1985). These machines had punched-card or punched-tape input and output devices and RAMs of 1000-word capacity. Physically, they were much more compact than ENIAC: some were about the size of a grand piano and required 2500 small electron tubes. This was quite an improvement over the earlier machines. The first-generation stored-program computers required considerable maintenance, usually attained 70% to 80% reliable operation, and were used for 8 to 12 years (Hazewindus,1988). Typically, they were programmed directly in machine language, although by the mid-1950s progress had been made in several aspects of advanced programming. This group of machines included EDVAC and UNIVAC, the first commercially available computers. With this invention, managers had even more power to perform calculations for such things as statistical demographic data (Beer, 1966). Before this time, it was very rare for a manager of a larger business to have the means to process large numbers in so little time. The UNIVAC was developed by John W. Mauchley and John Eckert, Jr. in the 1950s. Together they had formed the Mauchley-Eckert Computer Corporation, America's first computer company in the 1940s. During the development of the UNIVAC, they began to run short on funds and sold their company to the larger Remington-Rand Corporation. Eventually they built a working UNIVAC computer. It was delivered to the U. S. Census Bureau in 1951 where it was used to help tabulate the U. S. population (Hazewindus,1988). Early in the 1950s two important engineering discoveries changed the electronic computer field. The first computers were made with vacuum tubes, but by the late 1950s computers were being made out of transistors, which were smaller, less expensive, more reliable, and more efficient (Dolotta, 1985). In 1959, Robert Noyce, a physicist at the Fairchild Semiconductor Corporation, invented the integrated circuit, a tiny chip of silicon that contained an entire electronic circuit. Gone was the bulky, unreliable, but fast machine; now computers began to become more compact, more reliable and have more capacity. These new technical discoveries rapidly found their way into new models of digital computers. Memory storage capacities increased 800% in commercially available machines by the early 1960s and speeds increased by an equally large margin (Jacobs, 1975). These machines were very expensive to purchase or to rent and were especially expensive to operate because of the cost of hiring programmers to perform the complex operations the computers ran. Such computers were typically found in large computer centers operated by industry, government, and private laboratories staffed with many programmers and support personnel. By 1956, 76 of IBM's large computer mainframes were in use, compared with only 46 UNIVAC's (Chposky, 1988). In the 1960s efforts to design and develop the fastest possible computers with the greatest capacity reached a turning point with the completion of the LARC machine for Livermore Radiation Laboratories by the Sperry-Rand Corporation, and the Stretch computer by IBM. The LARC had a core memory of 98,000 words and multiplied in 10 microseconds. Stretch was provided with several ranks of memory having slower access for the ranks of greater capacity, the fastest access time being less than 1 microseconds and the total capacity in the vicinity of 100 million words. During this time the major computer manufacturers began to offer a range of computer capabilities, as well as various computer-related equipment (Jacobs, 1975). These included input means such as consoles and card feeders; output means such as page printers, cathode-ray-tube displays, and graphing devices; and optional magnetic-tape and magnetic-disk file storage. These found wide use in management for such applications as accounting, payroll, inventory control, ordering supplies, and billing. Central processing units for such purposes did not need to be very fast arithmetically and were primarily used to access large amounts of records on file. The greatest number of computer systems were delivered for the larger applications, such as in hospitals for keeping track of patient records, medications, and treatments given. They were also used in automated library systems and in database systems such as the Chemical Abstracts system, where computer records now on file cover nearly all known chemical compounds (Dolotta, 1985). The trend during the 1970s was, to some extent, away from extremely powerful, centralized computational centers and toward a broader range of applications for less-costly computer systems (Jacobs, 1975). Most continuous-process manufacturing, such as petroleum refining and electrical-power distribution systems, began using computers of relatively modest capability for controlling and regulating their activities. In the 1960s the programming of applications problems was an obstacle to the self-sufficiency of moderate-sized on-site computer installations, but great advances in applications programming languages removed these obstacles. Applications languages became available for controlling a great range of manufacturing processes, for computer operation of machine tools, and for many other tasks. In 1971 Marcian E. Hoff, Jr. , an engineer at the Intel Corporation, invented the microprocessor and another stage in the development of the computer began. A new revolution in computer hardware was now well under way, involving miniaturization of computer-logic circuitry and of component manufacture by what are called large-scale integration techniques. In the 1950s it was realized that scaling down the size of electronic digital computer circuits and parts would increase speed and efficiency and improve performance. However, at that time the manufacturing methods were not good enough to accomplish such a task. About 1960, photoprinting of conductive circuit boards to eliminate wiring became highly developed. Then it became possible to build resistors and capacitors into the circuitry by photographic means. In the 1970s entire assemblies, such as adders, shifting registers, and counters, became available on tiny chips of silicon. In the 1980s very large scale integration, VLSI, in which hundreds of thousands of transistors are placed on a single chip, became increasingly common. Many companies, some new to the computer field, introduced in the 1970s programmable minicomputers supplied with software packages. The size-reduction trend continued with the introduction of personal computers, which are programmable machines small enough and inexpensive enough to be purchased and used by individuals. One of the first of such machines was introduced in January 1975. Popular Electronics magazine provided plans that would allow any electronics wizard to build his own small, programmable computer for about $380. The computer was called the Altair 8800. Its programming involved pushing buttons and flipping switches on the front of the box. It didn't include a monitor or keyboard, and its applications were very limited. Even though, many orders came in for it and several famous owners of computer and software manufacturing companies got their start in computing through the Altair. For example, Steve Jobs and Steve Wozniak, founders of Apple Computer, built a much cheaper, yet more productive version of the Altair and turned their hobby into a business. After the introduction of the Altair 8800, the personal computer industry became a fierce battleground of competition. IBM had been the computer industry standard for well over a half-century. They held their position as the standard when they introduced their first personal computer, the IBM Model 60 in 1975. However, the newly formed Apple Computer company was releasing its own personal computer, the Apple II. The Apple I was the first computer designed by Jobs and Wozniak in Wozniak's garage, which was not produced on a wide scale. Software was needed to run the computers as well. Microsoft developed a Disk Operating System, MS-DOS, for the IBM computer while Apple developed its own software. Because Microsoft had now set the software standard for IBMs, every software manufacturer had to make their software compatible with Microsoft's. This would lead to huge profits for Microsoft. The main goal of the computer manufacturers was to make the computer as affordable as possible while increasing speed, reliability, and capacity. Nearly every computer manufacturer accomplished this and computers popped up everywhere. Computers were in businesses keeping track of even more inventories for managers. Computers were in colleges aiding students in research. Computers were in laboratories making complex calculations at high speeds for scientists and physicists. The computer had made its mark everywhere in management and built up a huge industry. The future is promising for the computer industry and its technology. The speed of processors is expected to double every year and a half in the coming years. As manufacturing techniques are further perfected the prices of computer systems are expected to steadily fall. However, since the microprocessor technology will be increasing, it's higher costs will offset the drop in price of older processors. In other words, the price of a new computer will stay about the same from year to year, but technology will steadily increase. Since the end of World War II, the computer industry has grown from a standing start into one of the biggest and most profitable industries in the United States. It now comprises thousands of companies, making everything from multi-million dollar high-speed supercomputers to printout paper and floppy disks. It employs millions of people and generates tens of billions of dollars in sales each year. Surely, the computer has impacted every aspect of people's lives. It has affected the way people work and play. It has made everyone's life easier by doing difficult work for people. The computer truly is one of the most incredible inventions in history to ever influence management, and life.

I. Greek Mathematicians Thales of Miletus Birthdate: 624 B. C. Died: 547-546 B. C. Nationality: Greek Title: Regarded as â€Å"Father of Science† Contributions: * He is credited with the first use of deductive reasoning applied to geometry. * Discovery that a circle is  bisected  by its diameter, that the base angles of an isosceles triangle are equal and that  vertical angles  are equal. * Accredited with foundation of the Ionian school of Mathematics that was a centre of learning and research. * Thales theorems used in Geometry: . The pairs of opposite angles formed by two intersecting lines are equal. 2. The base angles of an isosceles triangle are equal. 3. The sum of the angles in a triangle is 180 °. 4. An angle inscribed in a semicircle is a right angle. Pythagoras Birthdate: 569 B. C. Died: 475 B. C. Nationality: Greek Contributions: * Pythagorean Theorem. In a right angled triangle the square of the hypotenuse is equal to the sum of the squares on the other two sides. Note: A right triangle is a triangle that contains one right (90 °) angle.The longest side of a right triangle, called the hypotenuse, is the side opposite the right angle. The Pythagorean Theorem is important in mathematics, physics, and astronomy and has practical applications in surveying. * Developed a sophisticated numerology in which odd numbers denoted male and even female: 1 is the generator of numbers and is the number of reason 2 is the number of opinion 3 is the number of harmony 4 is the number of justice and retribution (opinion squared) 5 is the number of marriage (union of the ? rst male and the ? st female numbers) 6 is the number of creation 10 is the holiest of all, and was the number of the universe, because 1+2+3+4 = 10. * Discovery of incommensurate ratios, what we would call today irrational numbers. * Made the ? rst inroads into the branch of mathematics which would today be called Number Theory. * Setting up a secret mystical society, known as th e Pythagoreans that taught Mathematics and Physics. Anaxagoras Birthdate: 500 B. C. Died: 428 B. C. Nationality: Greek Contributions: * He was the first to explain that the moon shines due to reflected light from the sun. Theory of minute constituents of things and his emphasis on mechanical processes in the formation of order that paved the way for the atomic theory. * Advocated that matter is composed of infinite elements. * Introduced the notion of nous (Greek, â€Å"mind† or â€Å"reason†) into the philosophy of origins. The concept of nous (â€Å"mind†), an infinite and unchanging substance that enters into and controls every living object. He regarded material substance as an infinite multitude of imperishable primary elements, referring all generation and disappearance to mixture and separation, respectively.Euclid Birthdate: c. 335 B. C. E. Died: c. 270 B. C. E. Nationality: Greek Title: â€Å"Father of Geometry† Contributions: * Published a book called the â€Å"Elements† serving as the main textbook for teaching  mathematics  (especially  geometry) from the time of its publication until the late 19th or early 20th century. The Elements. One of the oldest surviving fragments of Euclid's  Elements, found at  Oxyrhynchus and dated to circa AD 100. * Wrote works on perspective,  conic sections,  spherical geometry,  number theory  and  rigor. In addition to the  Elements, at least five works of Euclid have survived to the present day. They follow the same logical structure as  Elements, with definitions and proved propositions. Those are the following: 1. Data  deals with the nature and implications of â€Å"given† information in geometrical problems; the subject matter is closely related to the first four books of the  Elements. 2. On Divisions of Figures, which survives only partially in  Arabic  translation, concerns the division of geometrical figures into two or more equal par ts or into parts in given  ratios.It is similar to a third century AD work by  Heron of Alexandria. 3. Catoptrics, which concerns the mathematical theory of mirrors, particularly the images formed in plane and spherical concave mirrors. The attribution is held to be anachronistic however by J J O'Connor and E F Robertson who name  Theon of Alexandria  as a more likely author. 4. Phaenomena, a treatise on  spherical astronomy, survives in Greek; it is quite similar to  On the Moving Sphere  by  Autolycus of Pitane, who flourished around 310 BC. * Famous five postulates of Euclid as mentioned in his book Elements . Point is that which has no part. 2. Line is a breadthless length. 3. The extremities of lines are points. 4. A straight line lies equally with respect to the points on itself. 5. One can draw a straight line from any point to any point. * The  Elements  also include the following five â€Å"common notions†: 1. Things that are equal to the same thi ng are also equal to one another (Transitive property of equality). 2. If equals are added to equals, then the wholes are equal. 3. If equals are subtracted from equals, then the remainders are equal. 4.Things that coincide with one another equal one another (Reflexive Property). 5. The whole is greater than the part. Plato Birthdate: 424/423 B. C. Died: 348/347 B. C. Nationality: Greek Contributions: * He helped to distinguish between  pure  and  applied mathematics  by widening the gap between â€Å"arithmetic†, now called  number theory  and â€Å"logistic†, now called  arithmetic. * Founder of the  Academy  in  Athens, the first institution of higher learning in the  Western world. It provided a comprehensive curriculum, including such subjects as astronomy, biology, mathematics, political theory, and philosophy. Helped to lay the foundations of  Western philosophy  and  science. * Platonic solids Platonic solid is a regular, convex poly hedron. The faces are congruent, regular polygons, with the same number of faces meeting at each vertex. There are exactly five solids which meet those criteria; each is named according to its number of faces. * Polyhedron Vertices Edges FacesVertex configuration 1. tetrahedron4643. 3. 3 2. cube / hexahedron81264. 4. 4 3. octahedron61283. 3. 3. 3 4. dodecahedron2030125. 5. 5 5. icosahedron1230203. 3. 3. 3. 3 AristotleBirthdate: 384 B. C. Died: 322 BC (aged 61 or 62) Nationality: Greek Contributions: * Founded the Lyceum * His biggest contribution to the field of mathematics was his development of the study of logic, which he termed â€Å"analytics†, as the basis for mathematical study. He wrote extensively on this concept in his work Prior Analytics, which was published from Lyceum lecture notes several hundreds of years after his death. * Aristotle's Physics, which contains a discussion of the infinite that he believed existed in theory only, sparked much debate in later cen turies.It is believed that Aristotle may have been the first philosopher to draw the distinction between actual and potential infinity. When considering both actual and potential infinity, Aristotle states this:  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   1. A body is defined as that which is bounded by a surface, therefore there cannot be an infinite body. 2. A Number, Numbers, by definition, is countable, so there is no number called ‘infinity’. 3. Perceptible bodies exist somewhere, they have a place, so there cannot be an infinite body. But Aristotle says that we cannot say that the infinite does not exist for these reasons: 1.If no infinite, magnitudes will not be divisible into magnitudes, but magnitudes can be divisible into magnitudes (potentially infinitely), therefore an infinite in some sense exists. 2. If no infinite, number would not be infinite, but number is infinite (potentially), therefore infinity does exist in some sense. * He was the founder of  formal logic, pioneere d the study of  zoology, and left every future scientist and philosopher in his debt through his contributions to the scientific method. Erasthosthenes Birthdate: 276 B. C. Died: 194 B. C. Nationality: Greek Contributions: * Sieve of Eratosthenes Worked on  prime numbers.He is remembered for his prime number sieve, the ‘Sieve of Eratosthenes' which, in modified form, is still an important tool in  number theory  research. Sieve of Eratosthenes- It does so by iteratively marking as composite (i. e. not prime) the multiples of each prime, starting with the multiples of 2. The multiples of a given prime are generated starting from that prime, as a sequence of numbers with the same difference, equal to that prime, between consecutive numbers. This is the Sieve's key distinction from using trial division to sequentially test each candidate number for divisibility by each prime. Made a surprisingly accurate measurement of the circumference of the Earth * He was the first per son to use the word â€Å"geography† in Greek and he invented the discipline of geography as we understand it. * He invented a system of  latitude  and  longitude. * He was the first to calculate the  tilt of the Earth's axis  (also with remarkable accuracy). * He may also have accurately calculated the  distance from the earth to the sun  and invented the  leap day. * He also created the first  map of the world  incorporating parallels and meridians within his cartographic depictions based on the available geographical knowledge of the era. Founder of scientific  chronology. Favourite Mathematician Euclid paves the way for what we known today as â€Å"Euclidian Geometry† that is considered as an indispensable for everyone and should be studied not only by students but by everyone because of its vast applications and relevance to everyone’s daily life. It is Euclid who is gifted with knowledge and therefore became the pillar of todayâ€℠¢s success in the field of geometry and mathematics as a whole. There were great mathematicians as there were numerous great mathematical knowledge that God wants us to know.In consideration however, there were several sagacious Greek mathematicians that had imparted their great contributions and therefore they deserve to be appreciated. But since my task is to declare my favourite mathematician, Euclid deserves most of my kudos for laying down the foundation of geometry. II. Mathematicians in the Medieval Ages Leonardo of Pisa Birthdate: 1170 Died: 1250 Nationality: Italian Contributions: * Best known to the modern world for the spreading of the Hindu–Arabic numeral system in Europe, primarily through the publication in 1202 of his Liber Abaci (Book of Calculation). Fibonacci introduces the so-called Modus Indorum (method of the Indians), today known as Arabic numerals. The book advocated numeration with the digits 0–9 and place value. The book showed the practical im portance of the new numeral system, using lattice multiplication and Egyptian fractions, by applying it to commercial bookkeeping, conversion of weights and measures, the calculation of interest, money-changing, and other applications. * He introduced us to the bar we use in fractions, previous to this, the numerator has quotations around it. * The square root notation is also a Fibonacci method.

(n -k)!. * Wrote a book entitled â€Å"Explanations of the difficulties in the postulates in Euclid's Elements† The treatise of Khayyam can be considered as the first treatment of parallels axiom which is not based on petitio principii but on more intuitive postulate. Khayyam refutes the previous attempts by other Greek and Persian mathematicians to prove the proposition.In a sense he made the first attempt at formulating a non-Euclidean postulate as an alternative to the parallel postulate. Favorite Mathematician As far as medieval times is concerned, people in this era were challenged with chaos, social turmoil, economic issues, and many other disputes. Part of this era is tinted with so called â€Å"Dark Ages† that marked the history with unfavourable events. Therefore, mathematicians during this era-after they undergone the untold toils-were deserving individuals for gratitude and praises for they had supplemented the following generations with mathematical ideas that is very useful and applicable.Leonardo Pisano or Leonardo Fibonacci caught my attention therefore he is my favourite mathematician in the medieval times. His desire to spread out the Hindu-Arabic numerals in other countries thus signifies that he is a person of generosity, with his noble will, he deserves to be†¦ III.

Favorite Mathematician Indeed, this period is supplemented with great mathematician as it moved on from the Dark Ages and undergone a rebirth. Enumerated mathematician were all astounding with their performances and contributions. But for me, Niccolo Fontana Tartaglia is my favourite mathematician not only because of his undisputed contributions but on the way he keep himself calm despite of conflicts between him and other mathematicians in this period. IV. Mathematicians in the 16th CenturyFrancois Viete Birthdate: 1540 Died: 23 February 1603 Nationality: F rench Contributions: * He developed the first infinite-product formula for ?. * Vieta is most famous for his systematic use of decimal notation and variable letters, for which he is sometimes called the Father of Modern Algebra.

(1614) Johannes Kepler Born: December 27, 1571 Died: November 15, 1630 (aged 58) Nationality: German Title: â€Å"Founder of Modern Optics† Contributions: * He generalized Alhazen's Billiard Problem, developing the notion of curvature. He was first to notice that the set of Platonic regular solids was incomplete if concave solids are admitted, and first to prove that there were only 13 â€Å"Archi medean solids. † * He proved theorems of solid geometry later discovered on the famous palimpsest of Archimedes. * He rediscovered the Fibonacci series, applied it to botany, and noted that the ratio of Fibonacci numbers converges to the Golden Mean. * He was a key early pioneer in calculus, and embraced the concept of continuity (which others avoided due to Zeno's paradoxes); his work was a direct inspiration for Cavalieri and others. He developed mensuration methods and anticipated Fermat's theorem (df(x)/dx = 0 at function extrema). * Kepler's Wine Barrel Problem, he used his rudimentary calculus to deduce which barrel shape would be the best bargain. * Kepler’s Conjecture- is a mathematical conjecture about sphere packing in three-dimensional Euclidean space. It says that no arrangement of equally sized spheres filling space has a greater average density than that of the cubic close packing (face-centered cubic) and hexagonal close packing arrangements.Marin Mersenn e Birthdate: 8 September 1588 Died: 1 September 1648 Nationality: French Contributions: * Mersenne primes. * Introduced several innovating concepts that can be considered as the basis of modern reflecting telescopes: 1. Instead of using an eyepiece, Mersenne introduced the revolutionary idea of a second mirror that would reflect the light coming from the first mirror. This allows one to focus the image behind the primary mirror in which a hole is drilled at the centre to unblock the rays. 2.Mersenne invented the afocal telescope and the beam compressor that is useful in many multiple-mirrors telescope designs. 3. Mersenne recognized also that he could correct the spherical aberration of the telescope by using nonspherical mirrors and that in the particular case of the afocal arrangement he could do this correction by using two parabolic mirrors. * He also performed extensive experiments to determine the acceleration of falling objects by comparing them with the swing of pendulums, r eported in his Cogitata Physico-Mathematica in 1644.He was the first to measure the length of the seconds pendulum, that is a pendulum whose swing takes one second, and the first to observe that a pendulum's swings are not isochronous as Galileo thought, but that large swings take longer than small swings. Gerard Desargues Birthdate: February 21, 1591 Died: September 1661 Nationality: French Contributions: * Founder of the theory of conic sections. Desargues offered a unified approach to the several types of conics through projection and section. * Perspective Theorem – that when two triangles are in perspective the meets of corresponding sides are collinear. * Founder of projective geometry. Desargues’s theorem The theorem states that if two triangles ABC and A? B? C? , situated in three-dimensional space, are related to each other in such a way that they can be seen perspectively from one point (i. e. , the lines AA? , BB? , and CC? all intersect in one point), then the points of intersection of corresponding sides all lie on one line provided that no two corresponding sides are†¦ * Desargues introduced the notions of the opposite ends of a straight line being regarded as coincident, parallel lines meeting at a point of infinity and regarding a straight line as circle whose center is at infinity. Desargues’ most important work Brouillon projet d’une atteinte aux evenemens des rencontres d? une cone avec un plan (Proposed Draft for an essay on the results of taking plane sections of a cone) was printed in 1639. In it Desargues presented innovations in projective geometry applied to the theory of conic sections. Favorite Mathematician Mathematicians in this period has its own distinct, and unique knowledge in the field of mathematics.They tackled the more complex world of mathematics, this complex world of Mathematics had at times stirred their lives, ignited some conflicts between them, unfolded their flaws and weaknesses but at the end, they build harmonious world through the unity of their formulas and much has benefited from it, they indeed reflected the beauty of Mathematics. They were all excellent mathematicians, and no doubt in it. But I admire John Napier for giving birth to Logarithms in the world of Mathematics. V. Mathematicians in the 17th Century Rene Descartes Birthdate: 31 March 1596 Died: 11 February 1650Nationality: French Contributions: * Accredited with the invention of co-ordinate geometry, the standard x,y co-ordinate system as the Cartesian plane. He developed the coordinate system as a â€Å"device to locate points on a plane†. The coordinate system includes two perpendicular lines. These lines are called axes. The vertical axis is designated as y axis while the horizontal axis is designated as the x axis. The intersection point of the two axes is called the origin or point zero. The position of any point on the plane can be located by locating how far perpendicularly from e ach axis the point lays.The position of the point in the coordinate system is specified by its two coordinates x and y. This is written as (x,y). * He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. * Descartes was also one of the key figures in the Scientific Revolution and has been described as an example of genius. * He also â€Å"pioneered the standard notation† that uses superscripts to show the powers or exponents; for example, the 4 used in x4 to indicate squaring of squaring. He â€Å"invented the convention of representing unknowns in equations by x, y, and z, and knowns by a, b, and c†. * He was first to assign a fundamental place for algebra in our system of knowledge, and believed that algebra was a method to automate or mechanize reasoning, particularly about abstract, unknown quantities. * Rene Descartes created analytic geometry, and discovered an early form of the law of conservation of momentum (the term momentum refers to the momentum of a force). * He developed a rule for determining the number of positive and negative roots in an equation.The Rule of Descartes as it is known states â€Å"An equation can have as many true [positive] roots as it contains changes of sign, from + to – or from – to +; and as many false [negative] roots as the number of times two + signs or two – signs are found in succession. † Bonaventura Francesco Cavalieri Birthdate: 1598 Died: November 30, 1647 Nationality: Italian Contributions: * He is known for his work on the problems of optics and motion. * Work on the precursors of infinitesimal calculus. * Introduction of logarithms to Italy.

In this book he developed the theory of mirrors shaped into parabolas, hyperbolas, and ellipses, and various combinations of these mirrors. * Cavalieri developed a geometrical approach to calculus and published a treatise on the topic, Geometria indivisibilibus continuorum nova quadam ratione promota (Geometry, developed by a new method through the indivisibles of the continua, 1635).In this work, an area is considered as constituted by an indefinite number of parallel segments and a volume as constituted by an indefinite number of parallel planar areas. * Cavalieri's principle, which states that the volumes of two objects are equal if the areas of their corresponding cross-sections are in all cases equal. Two cross-sections correspond if they are intersections of the body with planes equidistant from a chosen base plane. * Published tables of logarithms, emphasizing their practical use in the fields of astronomy and geography.Pierre de Fermat Birthdate: 1601 or 1607/8 Died: 1665 Jan 12 Nationality: French Contributions: * Early developments that led to infinitesimal calculus, inc luding his technique of adequality. * He is recognized for his discovery of an original method of finding the greatest and the smallest ordinates of curved lines, which is analogous to that of the differential calculus, then unknown, and his research into number theory. * He made notable contributions to analytic geometry, probability, and optics. * He is best known for Fermat's Last Theorem. Fermat was the first person known to have evaluated the integral of general power functions. Using an ingenious trick, he was able to reduce this evaluation to the sum of geometric series. * He invented a factorization method—Fermat's factorization method—as well as the proof technique of infinite descent, which he used to prove Fermat's Last Theorem for the case n = 4. * Fermat developed the two-square theorem, and the polygonal number theorem, which states that each number is a sum of three triangular numbers, four square numbers, five pentagonal numbers, and so on. With his gif t for number relations and his ability to find proofs for many of his theorems, Fermat essentially created the modern theory of numbers. Blaise Pascal Birthdate: 19 June 1623 Died: 19 August 1662 Nationality: French Contributions: * Pascal's Wager * Famous contribution of Pascal was his â€Å"Traite du triangle arithmetique† (Treatise on the Arithmetical Triangle), commonly known today as Pascal's triangle, which demonstrates many mathematical properties like binomial coefficients. Pascal’s Triangle At the age of 16, he formulated a basic theorem of projective geometry, known today as Pascal's theorem. * Pascal's law (a hydrostatics principle). * He invented the mechanical calculator. He built 20 of these machines (called Pascal’s calculator and later Pascaline) in the following ten years. * Corresponded with Pierre de Fermat on probability theory, strongly influencing the development of modern economics and social science. * Pascal's theorem. It states that if a hexagon is inscribed in a circle (or conic) then the three intersection points of opposite sides lie on a line (called the Pascal line).Christiaan Huygens Birthdate: April 14, 1629 Died: July 8, 1695 Nationality: Dutch Contributions: * His work included early telescopic studies elucidating the nature of the rings of Saturn and the discovery of its moon Titan. * The invention of the pendulum clock.

I saac Newton Birthdate: 4 Jan 1643 Died: 31 March 1727 Nationality: English Contributions: * He laid the foundations for differential and integral calculus.Calculus-branch of mathematics concerned with the study of such concepts as the rate of change of one variable quantity with respect to another, the slope of a curve at a prescribed point, the computation of the maximum and minimum values of functions, and the calculation of the area bounded by curves. Evolved from algebra, arithmetic, and geometry, it is the basis of that part of mathematics called analysis. * Produced simple analytical methods that unified many separate techniques previously developed to solve apparently unrelated problems such as finding areas, tangents, the lengths of curves and the maxima and minima of functions. Investigated the theory of light, explained gravity and hence the motion of the planets. * He is also famed for inventing `Newtonian Mechanics' and explicating his famous three laws of motion. * The first to use fractional indices and to employ coordinate geometry to derive solutions to Diophantine equations * He discovered Newton's identities, Newton's method, classified cubic plane curves (polynomials of degree three in two variables) Newton's identities, also known as the Newton–Girard formulae, give relations between two types of symmetric polynomials, namely between power sums and elementary symmetric polynomials.Evaluated at the roots of a monic polynomial P in one variable, they allow expressing the sums of the k-th powers of all roots of P (counted with their multiplicity) in terms of the coefficients of P, without actually finding those roots * Newton's method (also known as the Newton–Raphson method), named after Isaac Newton and Joseph Raphson, is a method for finding successively better approximations to the roots (or zeroes) of a real-valued function. Gottfried Wilhelm Von Leibniz Birthdate: July 1, 1646 Died: November 14, 1716 Nationality: GermanCont ributions: * Leibniz invented a mechanical calculating machine which would multiply as well as add, the mechanics of which were still being used as late as 1940. * Developed the infinitesimal calculus. * He became one of the most prolific inventors in the field of mechanical calculators. * He was the first to describe a pinwheel calculator in 1685[6] and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. * He also refined the binary number system, which is at the foundation of virtually all digital computers. Leibniz was the first, in 1692 and 1694, to employ it explicitly, to denote any of several geometric concepts derived from a curve, such as abscissa, ordinate, tangent, chord, and the perpendicular. * Leibniz was the first to see that the coefficients of a system of linear equations could be arranged into an array, now called a matrix, which can be manipulated to find the solution of the system. * He introduced several notations used to this day, for instance the integral sign ? representing an elongated S, from the Latin word summa and the d used for differentials, from the Latin word differentia.This cleverly suggestive notation for the calculus is probably his most enduring mathematical legacy. * He was the ? rst to use the notation f(x). * The notation used today in Calculus df/dx and ? f x dx are Leibniz notation. * He also did work in discrete mathematics and the foundations of logic. Favorite Mathematician Selecting favourite mathematician from these adept persons in mathematics is a hard task, but as I read the contributions of these Mathematicians, I found Sir Isaac Newton to be the greatest mathematician of this period.He invented the useful but difficult subject in mathematics- the calculus. I found him cooperative with different mathematician to derive useful formulas despite the fact that he is bright enough. Open-mindedness towards others opinion is what I discerned in him. VI.

Most notably, he introduced the concept of a function [2] and was the first to write f(x) to denote the function f a pplied to the argument x. He also introduced the modern notation for the trigonometric functions, the letter e for the base of the natural logarithm (now also known as Euler's number), the Greek letter ? for summations and the letter i to denote the imaginary unit. * The use of the Greek letter ? to denote the ratio of a circle's circumference to its diameter was also popularized by Euler. * Well known in analysis for his frequent use and development of power series, the expression of functions as sums of infinitely many terms, such as * Euler introduced the use of the exponential function and logarithms in analytic proofs.

For example, he proved the infinitude of primes using the divergence of the harmonic series, and he used analytic methods to gain some understanding of the way prime numbers are distributed. Euler's work in this area led to the development of the prime number theorem. He proved that the sum of the reciprocals of the primes diverges. In doing so, he discovered the connection between the Riemann zeta f unction and the prime numbers; this is known as the Euler product formula for the Riemann zeta function. * He also invented the totient function ? (n) which is the number of positive integers less than or equal to the integer n that are coprime to n. * Euler also conjectured the law of quadratic reciprocity. The concept is regarded as a fundamental theorem of number theory, and his ideas paved the way for the work of Carl Friedrich Gauss. * Discovered the formula V ?E + F = 2 relating the number of vertices, edges, and faces of a convex polyhedron. * He made great strides in improving the numerical approximation of integrals, inventing what are now known as the Euler approximations. Jean Le Rond De Alembert Birthdate: 16 November 1717 Died: 29 October 1783 Nationality: French Contributions: * D'Alembert's formula for obtaining solutions to the wave equation is named after him. * In 1743 he published his most famous work, Traite de dynamique, in which he developed his own laws of mot ion. * He created his ratio test, a test to see if a series converges. The D'Alembert operator, which first arose in D'Alembert's analysis of vibrating strings, plays an important role in modern theoretical physics. * He made several contributions to mathematics, including a suggestion for a theory of limits. * He was one of the first to appreciate the importance of functions, and defined the derivative of a function as the limit of a quotient of increments. Joseph Louise Lagrange Birthdate: 25 January 1736 Died: 10 April 1813 Nationality: Italian French Contributions: * Published the ‘Mecanique Analytique' which is considered to be his monumental work in the pure maths. His most prominent influence was his contribution to the the metric system and his addition of a decimal base. * Some refer to Lagrange as the founder of the Metric System. * He was responsible for developing the groundwork for an alternate method of writing Newton's Equations of Motion. This is referred to as ‘Lagrangian Mechanics'. * In 1772, he described the Langrangian points, the points in the plane of two objects in orbit around their common center of gravity at which the combined gravitational forces are zero, and where a third particle of negligible mass can remain at rest. He made significant contributions to all fields of analysis, number theory, and classical and celestial mechanics. * Was one of the creators of the calculus of variations, deriving the Euler–Lagrange equations for extrema of functionals. * He also extended the method to take into account possible constraints, arriving at the method of Lagrange multipliers. * Lagrange invented the method of solving differential equations known as variation of parameters, applied differential calculus to the theory of probabilities and attained notable work on the solution of equations. * He proved that every natural number is a sum of four squares. Several of his early papers also deal with questions of number theo ry. 1. Lagrange (1766–1769) was the first to prove that Pell's equation has a nontrivial solution in the integers for any non-square natural number n. [7] 2. He proved the theorem, stated by Bachet without justification, that every positive integer is the sum of four squares, 1770. 3. He proved Wilson's theorem that n is a prime if and only if (n ? 1)! + 1 is always a multiple of n, 1771. 4. His papers of 1773, 1775, and 1777 gave demonstrations of several results enunciated by Fermat, and not previously proved. 5.His Recherches d'Arithmetique of 1775 developed a general theory of binary quadratic forms to handle the general problem of when an integer is representable by the form. Gaspard Monge Birthdate: May 9, 1746 Died: July 28, 1818 Nationality: French Contributions: * Inventor of descriptive geometry, the mathematical basis on which technical drawing is based. * Published the following books in mathematics: 1. The Art of Manufacturing Cannon (1793)[3] 2. Geometrie descri ptive. Lecons donnees aux ecoles normales (Descriptive Geometry): a transcription of Monge's lectures. (1799) Pierre Simon Laplace Birthdate: 23 March 1749Died: 5 March 1827 Nationality: French Contributions: * Formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics. * Laplacian differential operator, widely used in mathematics, is also named after him. * He restated and developed the nebular hypothesis of the origin of the solar system * Was one of the first scientists to postulate the existence of black holes and the notion of gravitational collapse. * Laplace made the non-trivial extension of the result to three dimensions to yield a more general set of functions, the spherical harmonics or Laplace coefficients. Issued his Theorie analytique des probabilites in which he laid down many fundamental results in statistics. * Laplace’s most important work was his Celestial Mechanics published in 5 volumes between 1798-1827. In it he sought to give a complete mathematical description of the solar system. * In Inductive probability, Laplace set out a mathematical system of inductive reasoning based on probability, which we would today recognise as Bayesian. He begins the text with a series of principles of probability, the first six being: 1.Probability is the ratio of the â€Å"favored events† to the total possible events. 2. The first principle assumes equal probabilities for all events. When this is not true, we must first determine the probabilities of each event. Then, the probability is the sum of the probabilities of all possible favored events. 3. For independent events, the probability of the occurrence of all is the probability of each multiplied together. 4. For events not independent, the probability of event B following event A (or event A causing B) is the probability of A multiplied by the probability that A and B both occur. 5.The probability that A will occur, given th at B has occurred, is the probability of A and B occurring divided by the probability of B. 6. Three corollaries are given for the sixth principle, which amount to Bayesian probability. Where event Ai ? {A1, A2, †¦ An} exhausts the list of possible causes for event B, Pr(B) = Pr(A1, A2, †¦ An). Then: * Amongst the other discoveries of Laplace in pure and applied mathematics are: 1. Discussion, contemporaneously with Alexandre-Theophile Vandermonde, of the general theory of determinants, (1772); 2. Proof that every equation of an even degree must have at least one real quadratic factor; 3.Solution of the linear partial differential equation of the second order; 4. He was the first to consider the difficult problems involved in equations of mixed differences, and to prove that the solution of an equation in finite differences of the first degree and the second order might always be obtained in the form of a continued fraction; and 5. In his theory of probabilities: 6. Evalua tion of several common definite integrals; and 7. General proof of the Lagrange reversion theorem. Adrian Marie Legendere Birthdate: 18 September 1752 Died: 10 January 1833 Nationality: French Contributions: Well-known and important concepts such as the Legendre polynomials. * He developed the least squares method, which has broad application in linear regression, signal processing, statistics, and curve fitting; this was published in 1806. * He made substantial contributions to statistics, number theory, abstract algebra, and mathematical analysis. * In number theory, he conjectured the quadratic reciprocity law, subsequently proved by Gauss; in connection to this, the Legendre symbol is named after him. * He also did pioneering work on the distribution of primes, and on the application of analysis to number theory. Best known as the author of Elements de geometrie, which was published in 1794 and was the leading elementary text on the topic for around 100 years. * He introduced wh at are now known as Legendre functions, solutions to Legendre’s differential equation, used to determine, via power series, the attraction of an ellipsoid at any exterior point. * Published books: 1. Elements de geometrie, textbook 1794 2. Essai sur la Theorie des Nombres 1798 3. Nouvelles Methodes pour la Determination des Orbites des Cometes, 1806 4. Exercices de Calcul Integral, book in three volumes 1811, 1817, and 1819 5.Traite des Fonctions Elliptiques, book in three volumes 1825, 1826, and 1830 Simon Dennis Poison Birthdate: 21 June 1781 Died: 25 April 1840 Nationality: French Contributions: * He published two memoirs, one on Etienne Bezout's method of elimination, the other on the number of integrals of a finite difference equation. * Poisson's well-known correction of Laplace's second order partial differential equation for potential: today named after him Poisson's equation or the potential theory equation, was first published in the Bulletin de la societe philomati que (1813). Poisson's equation for the divergence of the gradient of a scalar field, ? in 3-dimensional space: Charles Babbage Birthdate: 26 December 1791 Death: 18 October 1871 Nationality: English Contributions: * Mechanical engineer who originated the concept of a programmable computer. * Credited with inventing the first mechanical computer that eventually led to more complex designs. * He invented the Difference Engine that could compute simple calculations, like multiplication or addition, but its most important trait was its ability create tables of the results of up to seven-degree polynomial functions. Invented the Analytical Engine, and it was the first machine ever designed with the idea of programming: a computer that could understand commands and could be programmed much like a modern-day computer. * He produced a Table of logarithms of the natural numbers from 1 to 108000 which was a standard reference from 1827 through the end of the century. Favorite Mathematician No ticeably, Leonard Euler made a mark in the field of Mathematics as he contributed several concepts and formulas that encompasses many areas of Mathematics-Geometry, Calculus, Trigonometry and etc.He deserves to be praised for doing such great things in Mathematics, indeed, his work laid foundation to make the lives of the following generation sublime, ergo, He is my favourite mathematician. VII. Mathematicians in the 19th Century Carl Friedrich Gauss Birthdate: 30 April 1777 Died: 23 February 1855 Nationality: German Contributions: * He became the first to prove the quadratic reciprocity law. * Gauss also made important contributions to number theory with his 1801 book Disquisitiones Arithmeticae (Latin, Arithmetical Investigations), which, among things, introduced the symbol ? or congruence and used it in a clean presentation of modular arithmetic, contained the first two proofs of the law of quadratic reciprocity, developed the theories of binary and ternary quadratic forms, state d the class number problem for them, and showed that a regular heptadecagon (17-sided polygon) can be constructed with straightedge and compass. * He developed a method of measuring the horizontal intensity of the magnetic field which was in use well into the second half of the 20th century, and worked out the mathematical theory for separating the inner and outer (magnetospheric) sources of Earth's magnetic field.Agustin Cauchy Birthdate: 21 August 1789 Died: 23 May 1857 Nationality: French Contributions: * His most notable research was in the theory of residues, the question of convergence, differential equations, theory of functions, the legitimate use of imaginary numbers, operations with determinants, the theory of equations, the theory of probability, and the applications of mathematics to physics. * His writings introduced new standards of rigor in calculus from which grew the modern field of analysis.In Cours d’analyse de l’Ecole Polytechnique (1821), by develo ping the concepts of limits and continuity, he provided the foundation for calculus essentially as it is today. * He introduced the â€Å"epsilon-delta definition for limits (epsilon for â€Å"error† and delta for â€Å"difference’). * He transformed the theory of complex functions by discovering integral theorems and introducing the calculus of residues. * Cauchy founded the modern theory of elasticity by applying the notion of pressure on a plane, and assuming that this pressure was no longer perpendicular to the plane upon which it acts in an elastic body.In this way, he introduced the concept of stress into the theory of elasticity. * He also examined the possible deformations of an elastic body and introduced the notion of strain. * One of the most prolific mathematicians of all time, he produced 789 mathematics papers, including 500 after the age of fifty. * He had sixteen concepts and theorems named for him, including the Cauchy integral theorem, the Cauchy-Sc hwartz inequality, Cauchy sequence and Cauchy-Riemann equations. He defined continuity in terms of infinitesimals and gave several important theorems in complex analysis and initiated the study of permutation groups in abstract algebra. * He started the project of formulating and proving the theorems of infinitesimal calculus in a rigorous manner. * He was the first to define complex numbers as pairs of real numbers. * Most famous for his single-handed development of complex function theory.The first pivotal theorem proved by Cauchy, now known as Cauchy's integral theorem, was the following: where f(z) is a complex-valued function holomorphic on and within the non-self-intersecting closed curve C (contour) lying in the complex plane. * He was the first to prove Taylor's theorem rigorously. * His greatest contributions to mathematical science are enveloped in the rigorous methods which he introduced; these are mainly embodied in his three great treatises: 1. Cours d'analyse de l'Ecol e royale polytechnique (1821) 2. Le Calcul infinitesimal (1823) 3.Lecons sur les applications de calcul infinitesimal; La geometrie (1826–1828) Nicolai Ivanovich Lobachevsky Birthdate: December 1, 1792 Died: February 24, 1856 Nationality: Russian Contributions: * Lobachevsky's great contribution to the development of modern mathematics begins with the fifth postulate (sometimes referred to as axiom XI) in Euclid's Elements. A modern version of this postulate reads: Through a point lying outside a given line only one line can be drawn parallel to the given line. * Lobachevsky's geometry found application in the theory of complex numbers, the theory of vectors, and the theory of relativity. Lobachevskii's deductions produced a geometry, which he called â€Å"imaginary,† that was internally consistent and harmonious yet different from the traditional one of Euclid. In 1826, he presented the paper â€Å"Brief Exposition of the Principles of Geometry with Vigorous Proofs o f the Theorem of Parallels. † He refined his imaginary geometry in subsequent works, dating from 1835 to 1855, the last being Pangeometry. * He was well respected in the work he developed with the theory of infinite series especially trigonometric series, integral calculus, and probability. In 1834 he found a method for approximating the roots of an algebraic equation. * Lobachevsky also gave the definition of a function as a correspondence between two sets of real numbers. Johann Peter Gustav Le Jeune Dirichlet Birthdate: 13 February 1805 Died: 5 May 1859 Nationality: German Contributions: * German mathematician with deep contributions to number theory (including creating the field of analytic number theory) and to the theory of Fourier series and other topics in mathematical analysis. * He is credited with being one of the first mathematicians to give the modern formal definition of a function. Published important contributions to the biquadratic reciprocity law. * In 1837 h e published Dirichlet's theorem on arithmetic progressions, using mathematical analysis concepts to tackle an algebraic problem and thus creating the branch of analytic number theory. * He introduced the Dirichlet characters and L-functions. * In a couple of papers in 1838 and 1839 he proved the first class number formula, for quadratic forms. * Based on his research of the structure of the unit group of quadratic fields, he proved the Dirichlet unit theorem, a fundamental result in algebraic number theory. He first used the pigeonhole principle, a basic counting argument, in the proof of a theorem in diophantine approximation, later named after him Dirichlet's approximation theorem. * In 1826, Dirichlet proved that in any arithmetic progression with first term coprime to the difference there are infinitely many primes. * Developed significant theorems in the areas of elliptic functions and applied analytic techniques to mathematical theory that resulted in the fundamental developme nt of number theory. * His lectures on the equilibrium of systems and potential theory led to what is known as the Dirichlet problem.It involves finding solutions to differential equations for a given set of values of the boundary points of the region on which the equations are defined. The problem is also known as the first boundary-value problem of potential theorem. Evariste Galois Birthdate: 25 October 1811 Death: 31 May 1832 Nationality: French Contributions: * His work laid the foundations for Galois Theory and group theory, two major branches of abstract algebra, and the subfield of Galois connections. * He was the first to use the word â€Å"group† (French: groupe) as a technical term in mathematics to represent a group of permutations. Galois published three papers, one of which laid the foundations for Galois Theory. The second one was about the numerical resolution of equations (root finding in modern terminology). The third was an important one in number theory, i n which the concept of a finite field was first articulated. * Galois' mathematical contributions were published in full in 1843 when Liouville reviewed his manuscript and declared it sound. It was finally published in the October–November 1846 issue of the Journal de Mathematiques Pures et Appliquees. 16] The most famous contribution of this manuscript was a novel proof that there is no quintic formula – that is, that fifth and higher degree equations are not generally solvable by radicals. * He also introduced the concept of a finite field (also known as a Galois field in his honor), in essentially the same form as it is understood today. * One of the founders of the branch of algebra known as group theory. He developed the concept that is today known as a normal subgroup. * Galois' most significant contribution to mathematics by far is his development of Galois Theory.He realized that the algebraic solution to a polynomial equation is related to the structure of a g roup of permutations associated with the roots of the polynomial, the Galois group of the polynomial. He found that an equation could be solved in radicals if one can find a series of subgroups of its Galois group, each one normal in its successor with abelian quotient, or its Galois group is solvable. This proved to be a fertile approach, which later mathematicians adapted to many other fields of mathematics besides the theory of equations to which Galois orig

Occurence at Owl Creek Bridge Approach

Occurence at Owl Creek Bridge Approach Ambrose Bierce, the author of the short story â€Å"An Occurrence At Owl Creek Bridge† used his own life experiences to create successful and expressive writing. The time period in which Bierce lived had a significant influence on his writing. Bierce’s experiences fighting the front lines in the civil war are brought out in his writings and short stories. The historic time period, in which Bierce placed the setting of â€Å"Owl Creek Bridge†, is very significant and creates a successful historic approach.Bierce tells â€Å"An Occurrence at Owl Creek Bridge† in the third person point of view. In turn the reader has limited knowledge and understanding of situations taking place. Bierce’s third person point of view, historical setting, and theme of death, brands â€Å"An Occurrence At Owl Creek Bridge† as a successful short story. The third person point of view affects the story in a number of ways. One sin ce the reader’s knowledge is limited; it is difficult to fully understand what the main character â€Å"Peyton Farquhar’s† is experiencing and the reasons behind his hanging.Bierce is the only person who knows how Peyton Farquhar thinks feels. Two, since he does not let the reader into the minds of the characters a sense of mystery is created. By the end of the story, Bierce seems both reliable and unreliable, he reveals that Farquhar is dead, but we also know that he imagined an escape. By introducing the reader to two different scenarios, Peyton being hung, and Peyton escaping into his wife’s arms, Bierce creates confusion for the reader. This third person approach enables Bierce’s story come to life and creates an interesting perspective.Bierce’s use of setting and historic time period in, â€Å"An Occurrence At Owl Creek Bridge†, enables this story to be viewed time and time again. The Civil War relates back to our American roots, it is a piece of history that every American has learned about and is the reason why America is known as the â€Å"Land of the Free†. Incorporating American History into the setting of this story allows â€Å"An Occurrence At Owl Creek Bridge† to be passed on from one generation to the next. Peyton Farquhar, the main character, is a southern farmer who is pro- slavery and a Confederate during the 1800’s (200).Peyton got caught in his attempt to destroy Owl Creek Bridge in order stop Union soldiers from reaching his family and farmland (200). This action is led to the reason behind his hanging. Bierce’s use of historic time period creates a successful, and relatable story for all readers. Death, the dreaded thought, Bierce plays into the human instinct to fight or cheat death. Peyton’s imagination comes into play when he does not want to accept the fact that he is going to die. Even though he is standing there, seconds away from being hung, Peyton imagines himself escaping.The story itself centers on an alternate reality that Farquhar creates in his mind, while he's really hanging, with no heartbeat, just activity in his brain. The idea is that Farquhar creates an escape in his mind, seconds before he is actually dead. Bierce utilizes denial as an essential element in the story, by exploring the human desire to cheat death, and escape fate. Peyton Farquhar tries to do so by examining any get away in his mind, before actually doing anything. By showing that even though, he escaped in his mind, Bierce demonstrates that death is unavoidable no matter what one does to escape it.Though death is not unexpected for Farquhar, he is ultimately unable to accept it. â€Å"As he pushes open the gate and passes up the wide walk, he sees a flutter of female garments; his wife, looking fresh and cool and sweet, steps down from the veranda to meet him. At the bottom of the steps she stands waiting, with a smile of ineffable joy, an attitude of matchless grace and dignity†¦As he is about to clasp her he feels a stunning blow upon the back of the neck; a blinding white light blazes all about him with a sound like the shock of a cannon- then all is darkness and silence. (204). Rather than accepting his own fate, Peyton resists death by imagining an elaborate fantasy of an alternate fate. Ambrose Bierce’s incorporation of setting, point of view, and theme produces an illustrious short story for all readers. Bierce makes the story relatable to all humans in the fight to cheat death. Knowledge of the civil war gears the reader’s understanding behind the actions that are taking place. Third person point of view is an effective way to keep the reader guessing and hanging on a limb.In an instant the whole story comes together, all the confusion, reality versus fantasy comes clear in the last sentence, â€Å"Peyton Farquhar was dead; his body, with a broken neck, swung gently from side to side beneath the ti mbers of the Owl Creek Bridge† (Bierce, 204). The reader finds out Peyton is dead at the very last second of the story in an instant Peyton gives in and loses his battle against death.

Athletics In MacGregors Sporting Landscape Essay Example for Free

Athletics In MacGregor’s Sporting Landscape Essay However, using tactics which corroborate teamwork and competitive factors which in theory will motivate students to strive and increase their participation levels. 1. 0 Introduction This report will provide a detailed analysis of the participation of athletics in Macgregor’s microcosm as the societal norm believe that the status quo is â€Å"uncool†, it is known that the position of Australia’s porting landscape is very weak as there is a lack of participation within Australia as a whole This can be answered by a simple formula created to find the reason why some sports have a lack in participation in mainstream society today, Figueroa’s framework, this formula is divided into Levels listed in the following Cultural, Structural, Institutional, interpersonal and individual levels, nonetheless, it Is concluded that it is up to the individual of whether they decide to participate in Athletics or not. The social factors that influence an individual’s decision to participate in Athletics may indirectly or directly impact them by shaping their values, attitudes and beliefs. Knowing this the individual may find themselves being subjective to the people and also the certain factors they face in society ranging from cultural differences to peers to themselves. Sociologist, Peter Figueroa, develop a framework that analyses the equity of social resources that can also be implemented into the participation of athletics. . 1 Individual Level It can be argued that when it comes to equity and access issues, the individual level is the most important. This is because, while all levels of Figueroa’s Framework can identify how equity and sporting opportunities are presented to an individual, in the end it is the individual’s choice that will determine his or her access and level of participation in physical education. Kiss, 2012) This level is specific to Macgregor’s sporting landscape as it highlights the lack of participation in students; nonetheless, these decisions about sport and physical activity are ultimately made by the individuals Genes, values, attitudes and personalities which are specific to each individual. 3. 0 Action plan In Macgregor’s deteriorating athletics program, the lack of participation in the carnivals can link to many reasons why they don’t compete in such events. Study shows that the majority of students would prefer to sit and chat with their friends instead of competing in athletics, however, to allow students to participate, an action plan was developed to; in theory create a more fun and enjoyable carnival thus increasing participation levels, using successful methods utilized in Australian sports such as Cricket, NRL, AFL, etc. The ideologies used within these sports can be integrated within the society of Macgregor’s microcosm shaping the status quo of Macgregor’s Athletics program in a more positive, enjoyable way. . 1 Justification of Action plan Throughout sporting history there are various techniques to strive for in order to have a successful carnival, the majority of successful sports share many similar techniques to better improve the participation of athletes in Australia such as making it more interactive for the audience thus improving their participation rates; for example, in tennis they implement a board that measures the speed of the serve for each game as well as the Olympics which show the world record for each event. nowing this; a supposed board that lists all the records of each event is shown publically pre-athletics carnival and during for students to observe and in theory become more motivated and strive to train and compete in the events believing they are able to break that record thus improving participation rates. Secondly, the appearance of famous sporting athletes have known to improve the participation of sports for example, NBA players frequently appear in many occasions of street basketball games as it obviously creates publicity, however, also improves the participation due to the fact that this allows the ‘average basketball fanatic’ who normally would watch their idol from the comfort of their own television, but in fact they are able to play side by side with their idol increasing their moral and motivation to play. This can also be implemented in the athletics carnival by having the famous athlete participate and motivate the students to join in and also create a slight sense of competition. Finally, it is a fact that Australians love to play team based sports as listed, AFL, Cricket, Football, NRL, Soccer, Basketball, Rugby League are in the top 10 Australian sports; this is 7 of the 10 sports that are shown. With this in mind, Students would be required to form groups of 3 and compete in the athletics carnival, with a twist; each event would hold a certain amount of points varying on the position the student places, 10points for 1st, 7points for 2nd, 5point for 3rd and participation will be worth 2 points. The team that scores the highest points will be rewarded with a prize, such as vouchers, etc. 4. 2 Links to survey results The action plan created was based on a census of the whole school to observe whether they would participate in athletics and their reasons to not. To justify the particular choices created in the action plan by showing the statistics which have guided the development as the spikes in the statistics assist in improving the participation by surveying the trend. The reason a record chart was implemented as it adds a competitive flair and students receive social rewards within the athletics carnival as 19% of students feel that there is no reward for students if they win the events, this will help students strive for the record instead of just trying to win. A massive 27% of students feel that they are not good enough for the athletics carnival and believe there is no point to participate and simply just socialize with their peers, with the appearance of a famous athlete; students would be motivated to part take in the events as the special guest can provide moral support and advice to improve their technique, etc. during the carnival as they can join in with the students. By creating team based events the 80% of students that prefer team sports are able to participate and at the same time fill the social void according to the 25% as they strive to motivate fellow teammates and allow each other perform better overall, also considering the 66% that would participate in the carnival if their peers were to join in. (Buckley, et al, 2013) 4. Links to research material including the individual level of the framework The research gathered of Figueroa’s framework on the individual level, it is realised that students values and beliefs are to strive for competition and rewards, as these factors have been fulfilled it will allow students to participate in a more enjoyable way, due to the fact that an individual’s values and beliefs reflect directly upon their parents, siblings and peers, however, it is proven that the individual learns to behave through the experience they have accumulated from mainly their peers, also the fact that students view the sports society in a ‘boring’ manner, they often assume they cannot socialise with their peers which majorly affect their participation rates. 5. 0 Conclusion Athletics In MacGregor’s Sporting Landscape.

Fordism and Post-Fordism Research Paper Example | Topics and Well Written Essays - 3000 words

Fordism and Post-Fordism - Research Paper Example This paper represents a historical shift from the Fordist methods in business to the post-Fordist methods and beyond. This paper will attempt to analyze the role played by management accounting in this historical shift by looking into both Fordism and post-Fordism while trying to realize how changing business requirements have been addressed by management accounting over time. 2. Fordism refers to an economic and social system that bases itself exclusively on the ideas of Henry Ford’s model of mass production. The use of Fordism is not restricted to the economic domain alone but instead, it has been applied to social as well as socio-economic systems too (Thompson, 2005). The essential side of Fordism relies on the fact that goods are produced cheaply in such a fashion that the people producing those goods are able to consume them. This facet of Fordism has made it popular in some Marxist circles as well. However, it has to be realized that the economic and social circumstance s that favored Fordism are now effectively over leading to a shift in Fordism. Some commentators call this shift post-Fordism though others disagree and contend that Fordism has been under constant evolution instead. De Grazia (2005) has defined Fordism as "the eponymous manufacturing system designed to spew out standardized, low-cost goods and afford its workers decent enough wages to buy them". In contrast to Grazia’s view, other commentators have described Fordism as an economic model for economic expansion that relies on mass production in order to create large volumes of standardized products using unskilled labor and specialized manufacturing equipment (Tolliday & Zeitlin, 1987). When these views are put in perspective of the manufacturing carried out by Henry Ford’s automobile plant at the turn of the twentieth century it becomes clear that both definitions are incomplete and tend to complement each other to produce a working definition. Hence, Fordism (for the purpose of this paper) is an economic process that allows the creation of standardized goods using unskilled labor and specialized manufacturing equipment such that the workers themselves are able to afford these goods. It must be realized at this point that Marxism, socialism and allied ideologies are distinct to Fordism in that Fordism still relies on a free market economy in order to thrive. The Marxist and socialist doctrines require that the control of businesses be relinquished to the government while there are no such stipulations in Fordism. Fordism has tended to rely on three major operating principles through its initial use at Henry Ford’s automobile manufacturing plant and then for its use in social and economic pathways. The fundamental operating principles are (Tolliday & Zeitlin, 1987): all products are standardized so that handmade craftsmanship is not required and is instead production is dealt with by machines; manufacturing relies on the utilization of spec ialized tools and equipment to make assembly lines a reality. This indicates that low level and unskilled workers are able to operate sophisticated manufacturing equipment in order to man assembly lines. Moreover, the nature of tasks performed on the assembly lines are monotonous and require little creative thinking; the workers working on these assembly lines are paid wages that are sufficient for them to purchase the things they produce.
