Physics General Relativity and 19th Century Essay Example

Physics: General Relativity and 19th Century Essay Physics   is a  natural science  that involves the study of  matter  and its  motion  through  spacetime, as well as all related concepts, including  energy  and  force. More broadly, it is the general analysis of  nature, conducted in order to understand how the  universe  behaves. Physics is one of the oldest  academic disciplines, perhaps the oldest through its inclusion of  astronomy. Over the last two millennia, physics had been considered synonymous with  philosophy,  chemistry, and certain branches of  mathematics  and  biology, but during the  Scientific Revolution  in the 16th century, it emerged to become a unique modern science in its own right. However, in some subject areas such as in  mathematical physics  and  quantum chemistry, the boundaries of physics remain difficult to distinguish. Physics is both significant and influential, in part because advances in its understanding have often translated into new  technologies, but also because new ideas in physics often resonate with other sciences, mathematics, and philosophy. For example, advances in the understanding of  electromagnetism  or  nuclear physics  led directly to the development of new products which have dramatically transformed modern-day society, such as  television,  computers,  domestic appliances, and  nuclear weapons; advances inthermodynamics  led to the development of motorized transport; and advances in  mechanics  inspired the development of  calculus. SCOPE AND AIMS OF PHYSICS Physics covers a wide range of  phenomena, from  elementary particles  (such as quarks, neutrinos and electrons) to the largest  superclusters  of galaxies.

[8]  Physics aims to describe the various phenomenon that occur in nature in terms of simpler phenomena. Thus, physics aims to both connect the things observable to humans to  root causes, and then to try to connect these causes together. For example, the  ancient Chinese  observed that certain rocks (lodestone) were attracted to one another by some invisible force. This effect was later called  magnetism, and was first rigorously studied in the 17th century. A little earlier than the Chinese, the  ancient Greeks  knew of other objects such as  amber, that when rubbed with fur would cause a similar invisible attraction between the two. This was also first studied rigorously in the 17th century, and came to be called  electricity. Thus, physics had come to understand two observations of nature in terms of some root cause (electricity and magnetism). However, further work in the 19th century revealed that these two forces were just two different aspects of one force –  electromagnetism. This process of unifying forces continues today, and electromagnetism and the  weak nuclear force  are now considered to be two aspects of the  electroweak interaction. Physics  is  closely  related to the other natural sciences and, in a sense, encompasses them. Chemistry, for example, deals with the interaction of atoms to form molecules; much of modern geology is largely a study of the physics of the earth and is known as geophysics; and astronomy deals with the physics of the stars and outer space. Even living systems are made up of fundamental particles and, as studied in biophysics and biochemistry, they follow the same types of laws as the simpler particles traditionally studied by a physicist. The  emphasis  on  the  interaction between particles in modern physics, known as the microscopic approach, must often be supplemented by a macroscopic approach that deals with larger elements or systems of particles. This macroscopic approach is indispensable to the application of physics to much of modern technology. Thermodynamics, for example, a branch of physics developed during the 19th century, deals with the elucidation and measurement of properties of a system as a whole and remains useful in other fields of physics; it also forms the basis of much of chemical and mechanical engineering. Such properties as the temperature, pressure, and volume of a gas have no meaning for an individual atom or molecule; these thermodynamic concepts can only be applied directly to a very large system of such particles. A bridge exists, however, between the microscopic and macroscopic approach; another branch of physics, known as statistical mechanics, indicates how pressure and temperature can be related to the motion of atoms and molecules on a statistical basis. Physics  emerged  as  a  separate science only in the early 19th century; until that time a physicist was often also a mathematician, philosopher, chemist, biologist, engineer, or even primarily a political leader or artist. Today the field has grown to such an extent that with few exceptions modern physicists have to limit their attention to one or two branches of the science. Once the fundamental aspects of a new field are discovered and understood, they become the domain of engineers and other applied scientists. The 19th-century discoveries in electricity and magnetism, for example, are now the province of electrical and communication engineers; the properties of matter discovered at the beginning of the 20th century have been applied in electronics; and the discoveries of nuclear physics, most of them not yet 40 years old, have passed into the hands of nuclear engineers for applications to peaceful or military uses. HISTORY OF PHYSICS Although  ideas  about  the physical world date from antiquity, physics did not emerge as a well-defined field of study until early in the 19th century. The  Babylonians,  Egyptians, and early Mesoamericans observed the motions of the planets and succeeded in predicting eclipses, but they failed to find an underlying system governing planetary motion. Little was added by the Greek civilization, partly because the uncritical acceptance of the ideas of the major philosophers Plato and Aristotle discouraged experimentation. Some  progress  was  made, however, notably in Alexandria, the scientific center of Greek civilization. There, the Greek mathematician and inventor Archimedes designed various practical mechanical devices, such as levers and screws, and measured the density of solid bodies by submerging them in a liquid. Other important Greek scientists were the astronomer Aristarchus of Samos, who measured the ratio of the distances from the earth to the sun and the moon; the mathematician, astronomer, and geographer Eratosthenes, who determined the circumference of the earth and drew up a catalog of stars; the astronomer Hipparchus, who discovered the precession of the equinoxes; and the astronomer, mathematician, and geographer Ptolemy, who proposed the system of planetary motion that was named after him, in which the earth was the center and the sun, moon, and stars moved around it in circular orbits. Little  advance  was  made in physics, or in any other science, during the Middle Ages, other than the preservation of the classical Greek treatises, for which the Arab scholars such as Averroes and Al-Quarashi, the latter also known as Ibn al-Nafis, deserve much credit. The founding of the great medieval universities by monastic orders in Europe, starting in the 13th century, generally failed to advance physics or any experimental investigations. The Italian Scholastic philosopher and theologian Saint Thomas Aquinas, for instance, attempted to demonstrate that the works of Plato and Aristotle were consistent with the Scriptures. The English Scholastic philosopher and scientist Roger Bacon was one of the few philosophers who advocated the experimental method as the true foundation of scientific knowledge and who also did some work in astronomy, chemistry, optics, and machine design. The  advent  of  modern  science followed the Renaissance and was ushered in by the highly successful attempt by four outstanding individuals to interpret the behavior of the heavenly bodies during the 16th and early 17th centuries. The Polish natural philosopher Nicolaus Copernicus propounded the heliocentric system that the planets move around the sun. He was convinced, however, that the planetary orbits were circular, and therefore his system required almost as many complicated elaborations as the Ptolemaic system it was intended to replace (see Copernican System). The Danish astronomer Tycho Brahe, believing in the Ptolemaic system, tried to confirm it by a series of remarkably accurate measurements. These provided his assistant, the German astronomer Johannes Kepler, with the data to overthrow the Ptolemaic system and led to the enunciation of three laws that conformed with a modified heliocentric theory. Galileo, having heard of the invention of the telescope, constructed one of his own and, starting in 1609, was able to confirm the heliocentric system by observing the phases of the planet Venus. He also discovered the surface irregularities of the moon, the four brightest satellites of Jupiter, sunspots, and many stars in the Milky Way. Galileos interests were not limited to astronomy; by using inclined planes and an improved water clock, he had earlier demonstrated that bodies of different weight fall at the same rate (thus overturning Aristotles dictums), and that their speed increases uniformly with the time of fall. Galileos astronomical discoveries and his work in mechanics foreshadowed the work of the 17th-century English mathematician and physicist Sir Isaac Newton, one of the greatest scientists who ever lived. NEWTON AND MECHANICS Starting  about  1665,  at the age of 23, Newton enunciated the principles of mechanics, formulated the law of universal gravitation, separated white light into colors, proposed a theory for the propagation of light, and invented differential and integral calculus. Newtons contributions covered an enormous range of natural phenomena: He was thus able to show that not only Keplers laws of planetary motion but also Galileos discoveries of falling bodies follow a combination of his own second law of motion and the law of gravitation, and to predict the appearance of comets, explain the effect of the moon in producing the tides, and explain the precession of the equinoxes. The  subsequent  development of physics owes much to Newtons laws of motion, notably the second, which states that the force needed to accelerate an object will be proportional to its mass times the acceleration. If the force and the initial position and velocity of a body are given, subsequent positions and velocities can be computed, although the force may vary with time or position; in the latter case, Newtons calculus must be applied. This simple law contained another important aspect: Each body has an inherent property, its inertial mass, which influences its motion. The greater this mass, the slower the change of velocity when a given force is impressed. Even today, the law retains its practical utility, as long as the body is not very small, not very massive, and not moving extremely rapidly. Newtons third law, expressed simply as â€Å"for every action there is an equal and opposite reaction,† recognizes, in more sophisticated modern terms, that all forces between particles come in oppositely directed pairs, although not necessarily along the line joining the particles. Gravity Newtons  more  specific contribution to the description of the forces in nature was the elucidation of the force of gravity. Today scientists know that in addition to gravity only three other fundamental forces give rise to all observed properties and activities in the universe: those of electromagnetism, the so-called strong nuclear interactions that bind together the neutrons and protons within atomic nuclei, and the weak interactions between some of the elementary particles that account for the phenomenon of radioactivity. Understanding of the force concept, however, dates from the universal law of gravitation, which recognizes that all material particles, and the bodies that are composed of them, have a property called gravitational mass. This property causes any two particles to exert attractive forces on each other (along the line joining them) that are directly proportional to the product of the masses, and inversely proportional to the square of the distance between the particles. This force of gravity governs the motion of the planets about the sun and the earths own gravitational field, and it may also be responsible for the possible gravitational collapse, the final stage in the life cycle of stars. See Black Hole; Gravitation; Star. One  of  the  most  important observations of physics is that the gravitational mass of a body (which is the source of one of the forces existing between it and another particle), is effectively the same as its inertial mass, the property that determines the motional response to any force exerted on it. This equivalence, now confirmed experimentally to within one part in 1013, holds in the sense of proportionality—that is, when one body has twice the gravitational mass of another, it also has twice the inertial mass. Thus, Galileos demonstrations, which antedate Newtons laws, that bodies fall to the ground with the same acceleration and hence with the same motion, can be explained by the fact that the gravitational mass of a body, which determines the forces exerted on it, and the inertial mass, which determines the response to that force, cancel out. The  full  significance of this equivalence between gravitational and inertial masses, however, was not appreciated until Albert Einstein, the theoretical physicist who enunciated the theory of relativity, saw that it led to a further implication: the inability to distinguish between a gravitational field and an accelerated frame of reference (see the Modern Physics: Relativity section of this article). The  force  of  gravity  is the weakest of the four forces of nature when elementary particles are considered. The gravitational force between two protons, for example, which are among the heaviest elementary particles, is at any given distance only 10-36 the magnitude of the electrostatic forces between them, and for two such protons in the nucleus of an atom, this force in turn is many times smaller than the strong nuclear interaction. The dominance of gravity on a macroscopic scale is due to two reasons: (1) Only one type of mass is known, which leads to only one kind of gravitational force, which is attractive. The many elementary particles that make up a large body, such as the earth, therefore exhibit an additive effect of their gravitational forces in line with the addition of their masses, which thus become very large. (2) The gravitational forces act over a large range, and decrease only as the square of the distance between two bodies. By  contrast,  the  electric charges of elementary particles, which give rise to electrostatic and magnetic forces, are either positive or negative, or absent altogether. Only particles with opposite charges attract one another, and large composite bodies therefore tend to be electrically neutral and inactive. On the other hand, the nuclear forces, both strong and weak, are extremely short range and become hardly noticeable at distances of the order of 1 million-millionth of an inch. Despite  its  macroscopic importance, the force of gravity remains so weak that a body must be very massive before its influence is noticed by another. Thus, the law of universal gravitation was deduced from observations of the motions of the planets long before it could be checked experimentally. Not until 1771 did the British physicist and chemist Henry Cavendish confirm it by using large spheres of lead to attract small masses attached to a torsion pendulum, and from these measurements also deduced the density of the earth. In  the  two  centuries  after Newton, although mechanics was analyzed, reformulated, and applied to complex systems, no new physical ideas were added. The Swiss mathematician Leonhard Euler first formulated the equations of motion for rigid bodies, while Newton had dealt only with masses concentrated at a point, which thus acted like particles. Various mathematical physicists, among them Joseph Louis Lagrange of France and Sir William Rowan Hamilton of Ireland extended Newtons second law in more sophisticated and elegant reformulations. Over the same period, Euler, the Dutch-born scientist Daniel Bernoulli, and other scientists also extended Newtonian mechanics to lay the foundation of fluid mechanics. Electricity and Magnetism Although  the  ancient  Greeks were aware of the electrostatic properties of amber, and the Chinese as early as 2700 bc made crude magnets from lodestone, experimentation with and the understanding and use of electric and magnetic phenomena did not occur until the end of the 18th century. In 1785 the French physicist Charles Augustin de Coulomb first confirmed experimentally that electrical charges attract or repel one another according to an inverse square law, similar to that of gravitation. A powerful theory to calculate the effect of any number of static electric charges arbitrarily distributed was subsequently developed by the French mathematician Simeon-Denis Poisson and the German mathematician Carl Friedrich Gauss. A  positively  charged  particle attracts a negatively charged particle, tending to accelerate one toward the other. If the medium through which the particle moves offers resistance to that motion, this may be reduced to a constant-velocity (rather than accelerated) motion, and the medium will be heated up and may also be otherwise affected. The ability to maintain an electromotive force that could continue to drive electrically charged particles had to await the development of the chemical battery by the Italian physicist Alessandro Volta in 1800. The classical theory of a simple electric circuit assumes that the two terminals of a battery are maintained positively and negatively charged as a result of its internal properties. When the terminals are connected by a wire, negatively charged particles will be simultaneously pushed away from the negative terminal and attracted to the positive one, and in the process heat up the wire that offers resistance to the motion. Upon their arrival at the positive terminal, the battery will force the particles toward the negative terminal, overcoming the opposing forces of Coulombs law. The German physicist Georg Simon Ohm first discovered the existence of a simple proportionality constant between the current flowing and the electromotive force supplied by a battery, known as the resistance of the circuit. Ohms law, which states that the resistance is equal to the electromotive force, or voltage, divided by the current, is not a fundamental and universally applicable law of physics, but rather describes the behavior of a limited class of solid materials. The  historical  concepts of magnetism, based on the existence of pairs of oppositely charged poles, had started in the 17th century and owe much to the work of Coulomb. The first connection between magnetism and electricity, however, was made through the pioneering experiments of the Danish physicist and chemist Hans Christian Oersted, who in 1819 discovered that a magnetic needle could be deflected by a wire nearby carrying an electric current. Within one week after learning of Oersteds discovery, the French scientist Andre Marie Ampere showed experimentally that two current-carrying wires would affect each other like poles of magnets. In 1831 the British physicist and chemist Michael Faraday discovered that an electric current could be induced (made to flow) in a wire without connection to a battery, either by moving a magnet or by placing another current-carrying wire with an unsteady—that is, rising and falling—current nearby. The intimate connection between electricity and magnetism, now established, can best be stated in terms of electric or magnetic fields, or forces that will act at a particular point on a unit charge or unit current, respectively, placed at that point. Stationary electric charges produce electric fields; currents—that is, moving electric charges—produce magnetic fields. Electric fields are also produced by changing magnetic fields, and vice versa. Electric fields exert forces on charged particles as a function of their charge alone; magnetic fields will exert an additional force only if the charges are in motion. These  qualitative  findings were finally put into a precise mathematical form by the British physicist James Clerk Maxwell who, in developing the partial differential equations that bear his name, related the space and time changes of electric and magnetic fields at a point with the charge and current densities at that point. In principle, they permit the calculation of the fields everywhere and any time from a knowledge of the charges and currents. An unexpected result arising from the solution of these equations was the prediction of a new kind of electromagnetic field, one that was produced by accelerating charges, that was propagated through space with the speed of light in the form of an electromagnetic wave, and that decreased with the inverse square of the distance from the source. In 1887 the German physicist Heinrich Rudolf Hertz succeeded in actually generating such waves by electrical means, thereby laying the foundations for radio, radar, television, and other forms of telecommunications. See Electromagnetic Radiation. The  behavior  of  electric and magnetic fields in these waves is quite similar to that of a very long taut string, one end of which is rapidly moved up and down in a periodic fashion. Any point along the string will be observed to move up and down, or oscillate, with the same period or with the same frequency as the source. Points along the string at different distances from the source will reach the maximum vertical displacements at different times, or at a different phase. Each point along he string will do what its neighbor did, but a little later, if it is further removed from the vibrating source. The speed with which the disturbance, or the message to oscillate, is transmitted along the string is called the wave velocity. This is a function of the medium, its mass, and the tension in the case of a string. An instantaneous snapshot of the string (after it has been in motion for a while) would show equispaced points having the same displaceme nt and motion, separated by a distance known as the wavelength, which is equal to the wave velocity divided by the frequency. In the case of the electromagnetic field one can think of the electric-field strength as taking the place of the up-and-down motion of each piece of the string, with the magnetic field acting similarly at a direction at right angles to that of the electric field. The electromagnetic-wave velocity away from the source is the speed of light. The  apparent  linear  propagation of light was known since antiquity, and the ancient Greeks believed that light consisted of a stream of corpuscles. They were, however, quite confused as to whether these corpuscles originated in the eye or in the object viewed. Any satisfactory theory of light must explain its origin and disappearance and its changes in speed and direction while it passes through various media. Partial answers to these questions were proposed in the 17th century by Newton, who based them on the assumptions of a corpuscular theory, and by the English scientist Robert Hooke and the Dutch astronomer, mathematician, and physicist Christiaan Huygens, who proposed a wave theory. No experiment could be performed that distinguished between the two theories until the demonstration of interference in the early 19th century by the British physicist and physician Thomas Young. The French physicist Augustin Jean Fresnel decisively favored the wave theory. Interference  can  be  demonstrated by placing a thin slit in front of a light source, stationing a double slit farther away, and looking at a screen spaced some distance behind the double slit. Instead of showing a uniformly illuminated image of the slits, the screen will show equispaced light and dark bands. Particles coming from the same source and arriving at the screen via the two slits could not produce different light intensities at different points and could certainly not cancel each other to yield dark spots. Light waves, however, can produce such an effect. Assuming, as did Huygens, that each of the double slits acts as a new source, emitting light in all directions, the two wave trains arriving at the screen at the same point will not generally arrive in phase, though they will have left the two slits in phase. Depending on the difference in their paths, â€Å"positive† displacements arriving at the same time as â€Å"negative† displacements of the other will tend to cancel out and produce darkness, while the simultaneous arrival of either positive or negative displacements from both sources will lead to reinforcement or brightness. Each apparent bright spot undergoes a timewise variation as successive in-phase waves go from maximum positive through zero to maximum negative displacement and back. Neither the eye nor any classical instrument, however, can determine this rapid â€Å"flicker,† which in the visible-light range has a frequency from 4 ? 014 to 7. 5 ? 1014 Hz, or cycles per second. Although it cannot be measured directly, the frequency can be inferred from wavelength and velocity measurements. The wavelength can be determined from a simple measurement of the distance between the two slits, and the distance between adjacent bright bands on the screen; it ranges from 4 ? 10-5 cm (1. 6 ? 10-5 in) for violet light to 7. 5 ? 10-5 cm (3 ? 10-5 in) for red light with intermediate wavelengths for the other colors. The  first  measurement of the velocity of light was carried out by the Danish astronomer Olaus Roemer in 1676. He noted an apparent time variation between successive eclipses of Jupiters moons, which he ascribed to the intervening change in the distance between Earth and Jupiter, and to the corresponding difference in the time required for the light to reach the earth. His measurement was in fair agreement with the improved 19th-century observations of the French physicist Armand Hippolyte Louis Fizeau, and with the work of the American physicist Albert Abraham Michelson and his coworkers, which extended into the 20th century. Today the velocity of light is known very accurately as 299,292. 6 km (185,971. 8 mi sec) in vacuum. In matter, the velocity is less and varies with frequency, giving rise to a phenomenon known as dispersion. Maxwells  work  contributed several important results to the understanding of light by showing that it was electromagnetic in origin and that electric and magnetic fields oscillated in a light wave. His work predicted the existence of nonvisible light, and today electromagnetic waves or radiations are known to cover the spectrum from amma rays, with wavelengths of 10-12 cm (4 ? 10-11 in), through X rays, visible light, microwaves, and radio waves, to long waves of hundreds of kilometers in length. It also related the velocity of light in vacuum and through media to other observed properties of space and matter on which electrical and magnetic effects depend. Maxwells discoveries, however, did not provide any insight into the mysterious medium, corresponding to the string, th rough which light and electromagnetic waves had to travel. Based on the experience with water, sound, and elastic waves, scientists assumed a similar medium to exist, a â€Å"luminiferous ether† without mass, which was all-pervasive (because light could obviously travel through a massless vacuum), and had to act like a solid (because electromagnetic waves were known to be transverse and the oscillations took place in a plane perpendicular to the direction of propagation, and gases and liquids could only sustain longitudinal waves, such as sound waves). The search for this mysterious ether occupied physicists attention for much of the last part of the 19th century. The  problem  was  further compounded by an extension of a simple problem. A person walking forward with a speed of 3. 2 km/h (2 mph) in a train traveling at 64. 4 km/h (40 mph) appears to move at 67. 6 km/h (42 mph), to an observer on the ground. In terms of the velocity of light the question that now arose was: If light travels at about 300,000 km/sec (about 186,000 mi/sec) through the ether, at what velocity should it travel relative to an observer on earth while the earth also moves through the ether? Or, alternately, what is the earths velocity through the ether? The famous Michelson-Morley experiment, first performed in 1887 by Michelson and the American chemist Edward Williams Morley using an interferometer, was an attempt to measure this velocity; if the earth were traveling through a stationary ether, a difference should be apparent in the time taken by light to traverse a given distance, depending on whether it travels in the direction of or perpendicular to the earths motion. The experiment was sensitive enough to detect even a very slight difference by interference; the results were negative. Physics was now in a profound quandary from which it was not rescued until Einstein formulated his theory of relativity in 1905. Thermodynamics A  branch  of  physics  that assumed major stature during the 19th century was thermodynamics. It began by disentangling the previously confused concepts of heat and temperature, by arriving at meaningful definitions, and by showing how they could be related to the heretofore purely mechanical concepts of work and energy. Heat And Temperature A  different  sensation is experienced when a hot or a cold body is touched, leading to the qualitative and subjective concept of temperature. The addition of heat to a body leads to an increase in temperature (as long as no melting or boiling occurs), and in the case of two bodies at different temperatures brought into contact, heat flows from one to the other until their temperatures become the same and thermal equilibrium is reached. To arrive at a scientific measure of temperature, scientists used the observation that the addition or subtraction of heat produced a change in at least one well-defined property of a body. The addition of heat, for example, to a column of liquid maintained at constant pressure increased the length of the column, while the heating of a gas confined in a container raised its pressure. Temperature, therefore, can invariably be measured by one other physical property, as in the length of the mercury column in an ordinary thermometer, provided the other relevant properties remain unchanged. The mathematical relationship between the relevant physical properties of a body or system and its temperature is known as the equation of state. Thus, for an ideal gas, a simple relationship exists between the pressure, p, volume V, number of moles n, and the absolute temperature T, given by pV = nRT, where R is the same constant for all ideal gases. Boyles law, named after the British physicist and chemist Robert Boyle, and Gay-Lussacs law or Charless law, named after the French physicists and chemists Joseph Louis Gay-Lussac and Jacques Alexandre Cesar Charles, are both contained in this equation of state. Until  well  into  the  19th century, heat was considered a massless fluid called caloric, contained in matter and capable of being squeezed out of or into it. Although the so-called caloric theory answered most early questions on thermometry and calorimetry, it failed to provide a sound explanation of many early 19th-century observations. The first true connection between heat and other forms of energy was observed in 1798 by the Anglo-American physicist and statesman Benjamin Thompson who noted that the heat produced in the boring of cannon was roughly proportional to the amount of work done. In mechanics, work is the product of a force on a body and the distance through which the body moves during its application. The First Law of Thermodynamics The  equivalence  of  heat and work was explained by the German physicist Hermann Ludwig Ferdinand von Helmholtz and the British mathematician and physicist William Thomson, 1st Baron Kelvin, by the middle of the 19th century. Equivalence means that doing work on a system can produce exactly the same effect as adding heat; thus the same temperature rise can be achieved in a gas contained in a vessel by adding heat or by doing an appropriate amount of work through a paddle wheel sticking into the container w

Clueless essays

Clueless essays Clueless is a modern day film based on the novel Emma by Jane Austin. The film includes the themes teen love, appearance, social class and friendship. There are 2 main characters in the film, the first is Cher, she is a rich teenage girl living in Beverly Hills and the second main character is Josh; who is her stepbrother who has come to stay. The film is about Cher trying to match make the new girl at Chers school, Ty, so that she will become popular, however in doing this Cher doesnt realise that she is only making herself and Ty unhappy. The main issue of the film is Chers journey to self-knowledge and understanding about herself and how other people, particularly Josh, try to help her get there. Cher is constructed as rich, beautiful, she lives in a nice house, is popular and incredibly clueless. The audience is positioned to responds to this construct by liking Cher from the beginning. It is often argued that the film Clueless has had great impact on the teenage generation. The opening two scenes in Clueless established Cher and her place in the world. The first scene showed all of Chers friends, her house and her jeep. Having all these things flashing in a montage the audience feels that they know what the story is about quickly at the beginning. During the montage the camera used tilt up shots, looking up at girls sunbaking on the rocks, these make the character look superior, and they used medium shots and also used almost every type of shot because this gives a wide view of the things in Chers life. This scene constructs Cher as a rich, selfish upper class girl. The opening scene in the film is set to the song Kids in America and Cher and her friends are a perfect match for the song. Cher and her friends are all good looking in this scene and the characters also all have nice clothes and therefore the audience is positioned to like them. The audience has been positioned to respond ...

The 21 ACT Tips You Should Be Using Today

The 21 ACT Tips You Should Be Using Today SAT / ACT Prep Online Guides and Tips The ACT has a straightforward test format, but that doesn’t mean it’s an easy test. You’re going to need to know how it’s structured and what kinds of questions to expect on each section in order to do well. In this article, I’ve listed 20 essential ACT tips, broken down by section, that will help you conquer the most difficult aspects of the test. ACT English Tips Tip #1: Know Your Grammar Rules The safest way to make sure you feel confident on the ACT English section is to memorize the grammar rules that will be on the test.On the ACT, it’s not enough to rely on whether something "sounds correct" to you.Since the test is standardized, you need to be prepared for the specific types of rules it will test and what it considers to be correct grammar.These won’t necessarily be rules you consistently use or are aware of in your everyday speech and writing. Thepassage-based format of ACT English can also present unique challenges.You need to make sure you’re reading the WHOLE sentence that you're being asked to edit.Sometimes the phrasing of an earlier part of a sentence will determine the correct answer for a change to the grammar of a later part. Tip #2: Watch Out for No Change Answers Many questions on ACT English that ask you about improving the grammar of sentences will also include a â€Å"no change† answer option.This option is risky because if you don’t know the grammar rule being broken, it’s easy to pick â€Å"no change† by accident.That’s why it’s important to be aware of how often you’re choosing â€Å"no change†. If it seems like you're choosing it more often than once every 4 or so questions, there might be something you’re missing.On any question where you’re tempted to pick â€Å"no change†, look at the sentence extra carefully and make sure there isn't another possibility.Read the sentence through again using all of the other options presented. If all of them still seem wrong, then â€Å"no change† is probably correct. ACT Writing Tips Tip #3: Plan Essay Examples Beforehand A great way to reduce stress on the ACT essay is to plan out the examples that you’ll use before the test.The essay prompts on the ACT are all relatively similar, so it’s not too difficult to come up with universal examples that could work for any of them.If you already have examples prepared, the hard work will be done for you.The only thing you’ll have to do during the test is relate them to the specific details of the prompt and to your opinions. You should also know that you don’t have to be factually accurate in your essay;if you have to twist the facts in your examples a bit to fit the needs of the prompt, that’s ok!The graders won't take points off because the essay is about your ability to structure your thoughts and answer the prompt logically, not about your level of outside knowledge. You can even say we actually landed on the moon! WAKE UP SHEEPLE Tip #4: Cater to the Essay Graders Just like all other parts of the ACT, the essay has to be as standardized as possible.This means there are a couple of things you can do to raise your score reliably: Make it at least two pages The grade of an essay isn’t technically supposed to be related to its length, but there is a positive correlation between essay length and essay score on the ACT.This does make some degree of sense: longer essays are going to provide more examples and support for the points they’re making.A good rule of thumb is to try and make your essay at least two pages long. Be sure to write an introduction and conclusion The quality of the introduction and conclusion of your essay will disproportionately affect your score, so you should ALWAYS include both of them.The essay graders are looking for a clear thesis that answers the question posed by the prompt and lists relevant examples.If you make it easy for the graders to figure out the point you’re trying to make, your score will come out better. Use varied word choice and writing style High scoring essays are the ones that flow well and are not repetitive.Try not to use the same phrases over and over or structure every topic sentence and transition the same way.Switch around your wording as much as possible while preserving the integrity of your original points. ACT Math Tips Tip #5: Know the Formulas It’s very important to know math formulas for the ACT because you aren’t provided with any of them on the test (except sometimes for individual questions that require the use of a weird formula).You’re going to waste a lot of unnecessary time on easy questions if you don’t memorize formulas, so you should get this out of the way first if you’re just starting to study for the ACT.Read our article on the formulas you need to know so you’ll be prepared! Tip #6: Fill in Content Gaps Sometimes knowing formulas isn’t enough if you haven’t encountered a certain type of question or content area in your classes before.When you do practice tests, make note of the questions you miss and see if there are any patterns in terms of question type.This could indicate weakness in a specific content area. Before you go any further with your math studying, you should focus on filling in the content gaps you find; this will improve your scores dramatically.Find study resources that deal directly with the problems you’re having, whether it’s geometry, algebra, trigonometry, or something else. Tip #7: Solve It on Your Own In order to fully understand your mistakes on ACT Math, it’s a good idea to force yourself to solve for the correct answer before reading answer explanations.When you get a question wrong, make note of the answer you should have gotten and see if you can arrive there without reading the explanation.You will have a much more solid grasp of the solution process if you go through it yourself rather than just reading about it.This exercise will give you a better chance of answering correctly if you come across a similar question in the future. Do we, though? ACT Reading Tips Tip #8: Read to Your Strengths The ACT is a very predictable test, and this is especially true on the reading section.There will always be four topic areas on ACT Reading in the following order: 1. Prose Fiction/Literary Narrative2. Social Science3. Humanities4. Natural Science Since you know what’s coming, you can make an informed decision about the order in which you’ll read the passages.If, for example, you’re more of a science person, you might decide to read the Natural Science passage or pair of passages first because it’s going to be the most interesting to you and the easiest to get through. This will give you an advantage because you’ll have enough time to answer questions that are easy for you and will earn you the most points.If you were to go through the reading section in order, you might end up rushing on the Natural Sciences passage(s) and not reaching your full score potential! Tip #9: Find a Good Passage Reading Method It’s extremely important to make sure you’re reading ACT passages in the most efficient way for your learning style. You don’t get much time per question on the reading section, so you have to use every minute wisely.Here are three potential reading strategies you might use: 1. Skim the passage first In my view, this is the best way to read ACT passages.By skimming first, you get a good sense of the main ideas of the passage and also might catch a lot of the details that the questions ask about.The best way to skim is to read the introduction and conclusion paragraphs, then the first and last sentences of every body paragraph.After skimming, you should try and answer any big picture questionsabout the passage first while the main ideas are fresh in your mind. 2. Do the questions first This is another viable option, even though it might seem risky.If you skip straight to the questions, you can start with detail questions and work your way up to big picture questions.In the process of finding the details, you will accumulate knowledge about the main ideas of the passage and eventually be able to answer the questions that are wider in scope.If you don't get all the information you need for big picture questions this way, you can always go back and skim, paying close attention to the introduction and conclusion paragraphs. 3. Read thoroughly This is the method that most people use instinctively because it’s what they’ve been told to do in school.Reading thoroughly can be fine if you’re a fast reader and have strong reading comprehension skills even under pressure.BUT if you experiment with the other methods and find that you can save yourself some time and not sacrifice any points, you’re probably better off using one of them instead. Whichever strategy you use, make sure you read the introductory blurb that’s included with each passage before you do anything else!This will give you helpful context for what to expect in the passage in terms of setting, content, and writing style. Tip #10: Predict the Answer Before you look at the answer choices for a reading question, you should try and think for yourself about what the answer might be.Doing this exercise can help to eliminate some of the confusion that might occur if you just looked at the answer choices right away.If you already have an answer in mind, you will be less compelled to pick answers that are plausible but not objectively correct. Sometimes it’s also helpful to rephrase the question in your own words if you find it to be confusing.This will likewise allow you to maintain your focus and avoid choosing answers that are not quite the right fit for the question based on the passage. (ACT questions only) Tip #11: Rely on Direct Evidence Remember that every question in the reading section has an answer that is supported by direct evidence in the passage!You shouldn’t have to make unsupported assumptions in order to answer any of the questions.There will always be SOMETHING that you can cite to give credence to your choice. If you can’t find evidence for an answer, you have to eliminate it even if it sounds plausible.There’s a big difference between plausible and correct on the ACT.Even with inference questions, which ask you to look beyond literal facts in the passages, you should still be able to find evidence for your answers.This is when you might have to look for context clues or connotation in words around the section of the passage you’re referencing in order to point you in the right direction. Tip #12: Get Intellectually Curious It might seem silly, but try and be interested in the material you’re reading.This will not only help you to absorb information better, but will also allow you to get something productive out of the test besides your score.You’ll have a much better time if you treat ACT reading as a pleasant learning experience and not a chore! ACT Science Tips Tip #13: Do the Conflicting Viewpoints Section Last The conflicting viewpoints passage on ACT Science is usually the most time-consuming part of the section and often the most difficult.It’s different from the rest of ACT Science because it doesn’t present any actual data.It just gives you a couple of passages that express different scientific opinions and asks you to answer questions about them. This requires a strong combination of reading comprehension and scientific reasoning skills.It’s a good idea to save conflicting viewpoints for last because you will eliminate the risk of getting stick on it and not having time to answer easier questions later on in the science section. Tip #14: Focus on the Visuals It’s best to ignore the introductions laden with technical terms that are provided to you on the science section and skip right to the graphs.When it comes down to it, almost all the questions you’ll see on ACT science can be answered just by looking at the data presented in the visuals.All of the other information is just there to distract and confuse you - don’t let it! Tip #15: Don’t Be Intimidated The main obstacle to succeeding on ACT science is just the fact that it LOOKS scary.Well, I’m here to tell you that it’s really not that hard - you don’t even have to know much science beyond what you learned back in elementary school. You may run into terms that you don’t know, but you most likely won’t have to understand them in order to answer questions correctly.They’re only in there to make this section seem more difficult than it actually is. This fools a lot of people, but if you stay calm and remember that you’ll never have to know any high-level science to do well, you should be fine.Focus solely on what the questions are asking and read the graphs logically, and you’ll do well! But you should probably watch out for that train behind you... Overall ACT Test Taking Tips Tip #16: Use Process of Elimination As I’ve written in another article, the fundamental rule of ACT Reading is that there is only one absolutely correct answer for each question, and you need to learn to eliminate the other three choices.This elimination rule applies to the other sections of the ACT as well.It’s far easier to work on eliminating incorrect answers than to try and pick out the correct answer right away. For each choice, ask yourself - where is the evidence? Does this answer the question?If anything in the choice doesn’t match up with what you read in the passage or the data you’re referencing, eliminate it.If an answer is only halfway right, it’s wrong! Tip #17: Skip Difficult Questions For students who struggle with running out of time on the ACT, lingering too much on hard questions is a major pitfall.If you find yourself floundering on a question, it’s a good idea to skip it on your first pass through the section.Just circle it so that it will be easier to spot when you go back through the questions. If you’re spending more than: 30 seconds on an English question60 seconds on a Math question45 seconds on a Reading or Science question SKIP IT! Take timed practice tests to experiment with how it feels to spend this much time on a question so that during the real ACT you’ll have a good sense of when you need to move on. Tip #18: Double Check Your Answers At the end of each section, if you have a few minutes left, you should go back through and check your answers to be sure you didn’t make any careless mistakes.As you’re answering questions, you can put a little star next to the ones you’re unsure about so you will know to focus on them if you have time at the end. Things to look for when double checking: 1. â€Å"LEAST† or â€Å"EXCEPT† questions - these are breeding grounds for careless mistakes. 2. Questions where you went back and forth between two answers - if you were unsure about a question, it's a good idea to go back and check it again. 3. Whichever types of questions you know you tend to have trouble with - for example, you might be extra careful with double checking the conflicting viewpoints passage questions for science. Tip #19: Do Your Bubbling Last You can actually save yourself a few minutes of time if you don’t bubble in your answers until the end of the section.As you go along, circle your choices in the test booklet so it will be easy for you to go through and fill in all the correct bubbles on your answer sheet later.This tip helps you to avoid the annoying process of switching between the test booklet and the answer sheet that will cost you a few seconds on every question. Before you decide to use this tip, make sure you’re capable of finishing the section with at least 3-5 minutes to spare.You don’t want to get stuck in a situation where you answered all the questions but didn’t have time to fill in all the bubbles. Another important thing to remember on the ACT is that you should always bubble in an answer for every question.There is no guessing penalty, so it’s to your advantage to fill in a bubble for every question even if you don’t have a clue what the answer is.You could get lucky, and if you don’t it won’t impact your score! Sooooo tippy (this has nothing to do with any specific tip I just wanted to include it somewhere) Tip #20: Get All Your Stuff Together the Night Before The day of the test, your palms will be sweaty, knees weak, arms heavy. The last thing you want to do is forget your ACT test ticket or pencils. So the day before the test, make sure you have all your stuff in one place, ideally in a backpack. The most important things: ACT admission ticket Acceptable photo ID #2 pencils and erasers ACT-Approved Calculator There are other optional things like snacks and water bottle we highly recommend. Don't even question it - just pack it in the day before so on the morning of the test, you'll be ready. Tip #21: Remain Calm When all is said and done, the best tip that anyone can give you is to stop psyching yourself out.Since your score for any given section on the ACT is riding on the single block of time that you have to answer the questions, freaking out about one hard question could really hurt you. If you run into a question you don’t know, just skip it!It might seem easier when you come back to it later with less time pressure. Keep in mind that it’s not the end of the world if you don’t get your highest scores on this test.You’ll have opportunities to take it again, and you can always improve! Review We've gone through 20 of the most important tips you should be using to do well on the ACT. Here's a complete list: English 1. Know your grammar rules2.

The Japanese Traditional Structure of Quick Response Assignment

The Japanese Traditional Structure of Quick Response - Assignment Example Light has been shed on how the supply chain structure leads to the success of such a business. Moreover, an analysis of the future effects of the Japan-Korean fashion collaboration in the setting of globalization in the fashion industry is elaborated. Major apparel firms work at introducing new styles every week. This is to be able to meet the demand of the Japanese young women market that is characterized by a fast-moving trend cycle with a great diversity of choices in styles. Studies show that fast fashion has a real effect on the supply chain for the fashion product, but the consumer demand is the main driving force that determines this fast fashion. This contrasts with the previous theories on the supply chain, which have been solely supplying driven aspects. Fast fashion is a phenomenon that is developed as a direct result of changing anticipations and demand from customers (Lea-Greenwood, 2006, p. 266). In addition, there is a tradition among the Japanese people that makes them prefer many varieties and have an interest in the craft. This calls for their fashion styles to be always changing apart from being unique from those of their counterparts. The organizations do not mainly depend on the seasonal collection, but they e nsure that there is a compressed time interval between the moment a product is designed and the moment that is used. This compression is attained either by lumping together selections that are more regular or through an ongoing redesigning and unchanging new production. In other words, the Just - in - Time (JIT) supply chain management theory is upheld. It entails â€Å"having the items of the right quality and quantity in the right place at the right time† (Cheng et al, 1996, p.2).  

How did the Constitution impact the development of American freedom Essay

How did the Constitution impact the development of American freedom - Essay Example The foremost reason for the proposal of the amendment of the articles was to ensure a harmonious operation of the states1 under an active central government. It was mainly to achieve union of the states given that it was not operational in most other states. The proposal for amendment, however, was not feasible. Many states were uncomfortable with the articles and cited possibilities of failure to materialize and function in such states. Since achieving a consensus among the thirteen states was a great challenge, the necessity for a new document led to the drafting of the constitution. Drafted in 1787 and ratified in 1788, the constitution became operational in 1789. The constitution would create a powerful central government as required by proponents of its drafting. The drafted constitution would turn out to form an efficient government that endured successful operation of the confederation. Some of the thirteen states greatly supported the necessity to change the articles that wer e the foundations of the initial government. According to the provisions of the articles, there were thirteen elected delegates. That formed the national congress. The basis of most decisions was on the conformity of majority delegates in the national congress since the state had single representative and vote. Advocates of reforms of the articles cited reasons as loose confederacy of the different states. The articles granted limited authority to the central government, over the states. States were too powerful under the articles. The

Five issues of the bmw

Five issues of the bmw The Bavarian Motor Industry Background Bayerische Motoren Werke AG (BMW) was founded in 1916 by Franz Josef Popp in Munich, Germany and it was mainly producing aircraft engines. The circular blue and white BMW logo or roundel is portrayed by BMW as the movement of an aircraft propeller, to signify the white blades cutting through the blue sky. The first aircaraft engine BMW produced was IIIa inline-six liquid-cooled engine in 1918 and it was prefered for its high-altitude performance. With German rearmament in the 1930s, the company again began producing aircraft engines for the Luftwaffe. Among its successful WWII engine designs were the BMW 132 and BMW 801 air-cooled radial engines, and the pioneering BMW 003 axial-flow turbojet, which powered the tiny, 1944-45-era jet-powered emergency fighter, the Heinkel He 162 Salamander. When WWI ended BMW was forced to stop producing aircraft engines by the terms of the Versailles Armistice Treaty. The company consequently shifted to motorcycle production in 1923 once the restrictions of the treaty started to be lifted where the motorcycles produced where able to brake speed records and win many races. In 1928-29 BMW started the production of cars where until today its production is being driven by the passion of a luxury sports car and inovative technology. Implimeantation Of The Five Topics New technology. New technology is very importand to multinationas companies in order to comunicta and share information. The issue here is the New Technology†¦ implementing it integrating with the existing ones The second issue is the Organisational Changes Requirements†¦ the difficulty in balancing change in Corporate Culture Organisational Structure. Security/threats. In large intustries and especially in the automotive intustry importand is to be able to secure all the vital inforamtion from industrial espionage, hackers or trespassers. The issue here is How important is IT security to management The secont is What are the impacts of IT security breaches? Ethic/social issues. In todays enteprisec a lot of importance has been given into the ethics of a company and it has great importance fot the companies image and the way the company oparates. The issue here is the use of electronic surveillance The second is Ethical Issues E-commerce and its issues. Nowadays a lot of corporate giants are using business intelligence and data mining systems in order to have a better view of what the customer prefers and be able t attract more customers. The issue here is the Data security ethics The second issue is Privacy Global MIS/risks. A lot of big companies expand to other countries in order to find new markets or cheaper workforce. The issue here is Consider Partners Collaboration -expertise, funds, etc Partner and supplier relationship management Varaiable Option Conidered For BMW New Technologies The implementation and integration of new technologies is very importand in the level of compatibility with the previous hard ware systems or software systems. In order to have a Continuous flow of information between all the countries BMW is established we need to check the technological and legal barriers of each country before continuing in the implementation of new technologies. The Organisational Changes Requirements†¦ the difficulty in balancing change in Corporate Culture Organisational Structure. In big complex organisations such as BMW the imports of new technologies might disrupt the current infrastructure and that because new computer software may vanquish the need of a customer support canter because everything can be atomically through internet. Security/Threats The issue here is How important is IT security to management. In the automotive industry its important to be able to keep vital documents of the company or prototypes of designs safe from industrial espionage or malicious hackers. The way for this to be done is through with Communications (networks) controls, firewalls or encryption programs. The secont is What are the impacts of IT security breaches? The impacts of security breach in any organisation can be disastrous in terms of industrial espionage or malicious phishing programs acquiring information about members of the organisation or employs in order to use their information for internet fraud. A catastrophic breach can be easily avoided with firewalls and separate back up drives. Ethic/Social Issues The issue here is the use of electronic surveillance. BMW uses electronic surveillance in order to be protected from bad employs or spies. In this case through agrremnts made with the government in companies owned building BMW has the right to have an electronic surveillance system but must have a sing informing the persons entering the buildings about the cctv. The second is Ethical Issues. BMW as multinational company known thought out the world is also directed by its image in ethical issues. Since BMW has a fun club in the internet it is obliged by the law and for ethical issues to have the information of the members strictly confidential and not be exploited for commercial reasons. E-commerce The issue here is the Data security ethics. BMW uses e-commerce in order to have information on the customers likes dislikes and be able to be more attractive to customers. All the informations are gathered by business intelligence programs. Internet users entering the companys site are being monitored on what they browse the data collected are being stored in order to be analyzed in the design of an attractive offer. All information gathered is a part of the legal authority on the companys web site. The second issue is Privacy. Information gathered for the research of the company is to be kept confidential and private for the company use only. In my opinion the company should keep the record for the use of new ideas and records of royal customers. Global MIS/Risks The issue here is Consider Partners Collaboration -expertise, funds, etc. In global companies operating in different countries in the world means co-operations with several other organizations or parties. Since BMW has factories in Germany Austria South Africa and America they need to have partners with vehicle construction knowledge in order for them to be more efficient and improve the quality. This why in countries that BMW has factories BMW it has educational programs with technical, managerial and specialist training as well as providing assistance for higher education. The second issue is the Partner and supplier relationship management. BMW operates factories and dealerships in all over the world so it is very important to have a constant communication with all the partners and the suppliers. The best solution is a global system network between all the partners and suppliers using web services in order to be informed on any supply needs and the daily development. Lessons Learned So Far And Options Considered Differently. In a global company like BMW there are many risk of the regarding the information systems and the information technologies. In the automotive industry it is very important to have a comparative advantage over your rivals by being innovative and have a better understanding of the customers needs. All the information that is gathered and stored its of critical importance to keep them safe away from industrial espionage or hackers or phisers. It is also important to have all the internet or business application from programs like Trojan viruses, viruses, worms, or spasms because the can slow the performance of an application or even worse destroy it losing all information that are not stored. There is a big risk of internet crime of stealing personal information or information extortionists. There is a great importance from keeping your data systems or applications protected from all the possible intruders either living like hackers or social engineers or non living like programs viruses worms etc. New technology is being conastly developed either in information systems telecomunications or sience. New technoligy in the case of BMW means better production better informaion systems and comunication between all the dealerships and factoris acros the world. Inforamtion technology is based on information systems and information sharing technologies witch they are supported by communication networks such us the internet intranet or extranet wich it can be either cable or WiFi. This way multinational compaies like BMW can communicate with the factories and offices around the world and keep a constand flow of information through private server. So in todays wolrd the new technology can give the competitive advantage to help sustaining a healthy bussines with an excelent communication with factories all over the world. Ethical issues play a major part in global companies for their legal perception of the law on workforce and the public image of the company. BMW is using 29% of its earning in educational programs in third world countries something which shows respect for the workforce and a good public image. Nike for example had ethical legal issues because it had child workers in their factories. Ethical and legal issues also play role on the information systems gathering information about the customers or fun clubs of BMW through the internet or using electronic surveillance for security in private areas. In this case all information gathered or the video recorded from the surveillance cameras is legally restricted to be on public broad cast and BMW has secure storage places for all this material. E-commerce is the new way for global companies to have detailed information on their customers through surveys or intelligence programmes like data mining or predictive analysis to be able to have a better understanding of the customers choices and like in order to attract them or dislikes in order to improve. All those are part of the new technologies implemented by global companies that make full use of the internet. Of course all those information are to be used only by companys special personnel for the design of a new product or the improvement of an existing one. Major manufacturing companies that want to expand in to other countries either for its market of for the cheap labour they use globalisation systems in order to be in contact with all the factories all over the world. Global information systems like extranets XML web services electronic data interchange etc. in order for BMW headquarters to have full knowledge of all production in all of the factories scattered across the world they need to have a clear direct link with all the factories and dealerships. Its also important to have partners with who they can have a good communication and be trained in a level of mutual understanding this is why BMW has training programs teaching managerial and manufacturing courses in order to improve the quality and the efficiency. Conclusion And Improvement Ideas. In the end as we can see through the big history of BMW from 1916 to today BMW is a colossal in the industry area with factories all over the world and the need for information systems and technologies in order for the headquarters in Munich to coordinate the manufacturing plants and assembly plants all over the world with out delays from the suppliers. However the future of the e-commerce and information system is a long way a head because a new technology is being developed so the potentials of more effective communications and more improved security systems for the newly developed threats to the security of a system. So in the end global organisations like BMW will constantly rely on information and communication systems and new technology in order to operate though out the whole world.

Human Rights Essay

In the bible it says being a homosexual or transgender is a sin and therefore isn’t permitted into heaven. People make signs saying â€Å"GOD HATES FAGS†, â€Å"FAGS ARE WORTHY OF DEATH†, yet it also says in the bible god loves everyone, sinner or not. Our society has created this propaganda that homosexuals and transsexuals are horrible people and should be eliminated. This is biased. Now here’s a question. Have we ever stop and thought about how they feel about all this hatred and isolation towards them? They didn’t wake up one day and decided to be gay or dress like the opposite sex they are.In the year of 1998 a major hate crime case set in, the Matthew Shepard trial. Matthew Wayne Shepard, An openly gay American student at the University of Wyoming, was tortured and killed near Laramie, Wyoming on October 1998, only 21 years old. He was attacked on the night of October 6-7 and died five days later, October 12th. Matthew lived a life outside of the sexual norm of our society. As a result of this he was brutally murdered. This case commenced major public reaction all around the world and opened thousands of eyes.This case angered the homosexual societies. Most importantly battered Matthew’s family and changed their lives forever. Matthews’s journey began on December 1st, 1976. He was born to Judy and Dennis Shepard in Casper, Wyoming. Matthew’s father described him as an optimistic and excepting young man. Matthew could relate to almost everyone. He was very approachable, or easy to talk to, always was up for a new challenge, made friends easily, and he had a great passion for equality and always defended people’s differences.Throughout his life, he was always moving schools and traveling. With that being said his experiences fueled his love for traveling and gave him the chance to socialize where ever he went. Matthew had friends all around the world who loved and cared for him. He was a good ki d, didn’t bother anyone, was always friendly, and willing to give a helping hand. That all changed unfortunately while Matthew was on a high school trip in Morocco, he was raped. This caused him to have depression and panic attacks.When he came back from the trip his mother Judy Shepard took him back to Casper, Wyoming. Once back home he was required to take pills for his panic attacks. Matthew then went back to college, but didn’t stay in Casper for long. While in college he met Romaine Patterson and became really good friends with her. They both decide they would transfer to a different college in Laramie. Matthew struggled once he went to Laramie. He lived in the most dangerous part of town, where people didn’t accepted â€Å"gays† and his depression took over. Matthew started to do drugs.It took him a while to dig his way out of this hole he made himself but with the help of Romaine and his parents he made it. Went back to school again and became a fi rst year political science major at the University of Wyoming, in Laramie. One night on October 6 of 1998 he decided he would go to Laramie and get a drink, on his lonesome. He arrived at the fireside lounge. Sitting at the bar alone, just him and his beer, but he had a sudden urge to look over at the pool tables and notices two guys looking at him, quickly he looks away minding his own business.Again he makes eye contact with the two guys, Then goes walking off to the bathroom, as he’s walking away both guys mumble something to each other and follow Matthew. He’s washing his hands when both guys walk in. there’s no paper towels to dry his hands in and that’s when Russell Henderson give Matthew some paper towels and says that they are both gay as well. A sigh of relief for Matthew, They continue to speak and Matthew within a few sentences began to trust them, and eventually asked for a ride home.At the bar Aaron and Russell planned to only rob Shepard, bu t during the trial Aaron Mckinney said as they we’re driving Shepard home Shepard was rubbing his leg and grabbing his genital areas, thus Matthews actions, that is what supposedly caused Aaron to break out and beat Matthew. Mr. Mckinney says that he hit Matthew about 6 times on the head while they we’re driving not to his house but to a remote area. Then once arrived to this place Russell then tied Matthew to a fence, that is when Mr. Mckinney pistol whipped, punched, and kicked Matthew one to many times to the back of his head.Once the job was done, both men left the scene. Eighteen hours later Matthew still alive was found by Aaron Kreifels who mistook Matthew for a scarecrow. Matthew’s face was covered in blood; the only clear spots on his face were the tear drops going down his face. Matt hadn't actually been tied like a scarecrow: when he was approached first by the mountain biker, Aaron Kreifels, and then by Reggie Fluty, the sheriff's deputy who answered Kreifels's emergency call, Matt lay on his back, head propped against the fence, legs outstretched. His hands were lashed behind him and tied barely four inches off the ground to a fencepost.He was then taking to Ivinson Memorial Hospital in Laramie, then to Poudre Valley Hospital in Fort Collins. Shepard suffered a fracture from the back of his head to the front of his right ear. He had severe brain stem damage, which affected his body's ability to regulate heart rate, body temperature and other vital signs. There were also about a dozen small lacerations around his head, face and neck. His injuries were deemed too severe for doctors to operate. Shepard never regained consciousness and remained on full life support.Matt died at 12:53 A. M.  on October 12, 1998, at Poudre Valley Hospital in Fort Collins. Matthew was brutally murdered, and was given no second chance. No one heard his screams, his cries; no one was there to comfort him, he didn’t get to see his family or say good bye to loved ones, no one knew where he went or where he was going, he was gone and no one knew. Just like in Night by Elie Wiesel, no one heard his cries just like Matthew, although he had his father with him, he still felt alone; slowly his soul was beginning to die, just like Matthew slowly died those last five days in the hospital.No one deserves to die by being tortured, and treated as if they were nothing. The life and death of Matthew Shepard changed the way we talk about, and deal with, hate in America. Since his death, Matt’s legacy has challenged and inspired millions of individuals to erase hate in all its forms. Although Matt’s life was short, his story continues to have a great impact on young and old alike. His legacy lives on in thousands of people who actively fight to replace hate with understanding, compassion, and acceptance.
