Wind Tunnels :: essays research papers

Wind Tunnels In this report I will talk about the wind tunnel. I will described what they are used for. The different types of wind tunnels from the slow speed subsonic to the high speed hypersonic tunnels. I will also give A few examples of the wind tunnels used today. The wind tunnel is a device used by many people, from High school students to NASA engineers. The wind tunnel is a device used to test planes to see how well it will do under certain conditions. The plane maybe as big as a full size 747 or as small as a match. To understand how a wind tunnel is used to help in the designing process you have to know how a wind tunnel works. How Wind Tunnels Work A wind tunnel is a machine used to fly aircraft's, missiles, engines, and rockets on the ground under pre-set conditions. With a wind tunnel you can chose the air speed, pressure, altitude and temperature to name a few things. A wind tunnel is usually has a tube like appearance with which wind is produced by a large fan to flow over what they are testing (plane, missiles, rockets, etc.)or a model of it. The object in the wind tunnel is fixed and placed in the test section of the tunnel and instruments are placed on the model to record the aerodynamic forces acting on the model. Types of Wind Tunnels There are four basic types of wind tunnels. Which are low subsonic, transonic, supersonic, and hypersonic. The wind tunnels are classified by the amount of speed they can produce. The subsonic has a speed lower then the speed of sound. The transonic has a speed which is about equal to the speed of sound (Mach 1 760 miles per hour at sea level). . The supersonic (Mach 2.75 to 4.96) has a speed of about five times the speed of sound And the fasts of them all the hypersonic (Mach39.5) which has a speed of more then 30,000 miles per hour. Wind Tunnel Test There are basically two types of wind tunnel test which are static stability and the pressure test. With these two test you can determine the aerodynamic characteristics of the aircraft. The static stability test the measures the forces moments due to the external characteristic. These forces include axial, side and normal force, rolling, pitching and yawing moment. This forces are found by using a strain gauge which is located on the external portion of the plane. It measures the external flow fields. Then the shadowgraph is used to show the shock waves and flow fields at a certain speed or angle of

Blue spider case study

Fellness Systems Engineering Principles: Blue Spider Case Study Name: Professor: Course Name: Subject: Date Due: Executive summary Parks Corporation is a firm involved in R & D business; the firm does projects on behalf of the Department of Defense. Over the years, Parks Corporation has transformed its focus from the R & D business to being involved in low cost production. The process of retrenching employees in the firm was as a result of the recession and this brought down the number of staff to 2200 down from 6700.The upturn in the spending habit of the Department of Defense in 1975 made the firm hanged its corporate strategy. The new strategy involved Parks improving its R & D staff in the engineering section. Considering the salaries which Parks was providing, there was limitation in terms of getting experienced engineers and hence they decided to employ the young who lacked experience. One of the recruits from college was Gary Anderson.Despite his lack of experience, Gary Ander son was a great production engineer and this resulted to his promotion to a senior scientist who was in Judge of the R & D activities conducted at the Mechanical Engineering department. In 1978, Parks made a decision to bid for the 1st phase of Blue Spider Project together with Lord Industries being the major contractor for the Spartan Program for the Army. This project was meant to ensure improved structural capabilities as well as the age life related to the short range of the tactical missile; the tactical missile was showing failure because of fatigue as it had been used in the field for 6 years.One of the conditions for the choice of the bid for subcontracting was based on the low bid with expertise in technical and also the management performance. Parks Corporation had a feeling that they had a unique advantage over TTS competitors since they had a previous experience in the Lord Industries projects. From the onset of this project, there was a problem which can be identified; this was that Gary Anderson was given the chance to be the head of project management due to his background in R & D; however, he lacks the experience vital in managing projects.It is worth noting that the technical background is not enough to ensure an effective project manager. In specific a number of problems can be identified as the project took off; one of the problems is the informal way of starting the project was en and there was no particular guidelines, the proposal for the project was done in unethical manner, Parks Corporation seem to have issues in its behavior, problems in the operational process as well as problems in the organization's architecture/ relations which was not clearly defined and also followed.Project management often includes 9 specific areas of integration, management scope, time management, the cost management, the quality management, the human resource management, the communications management, the risk management as well as procurement management al l of which lacked in the Blue spider project. Table of Contents Table of figures 1.Introduction 1. 1 Summary of the Case study Blue Spider Case study represents a case where systems engineering principles failed; this case represents one of the failed projects as the head of the project team lacked the experience to manage projects and hence failure to use the systems engineering principles.Among the major events in the case study are Gary Anderson accepting the position of the project manager; the DoD have asked Lord Industries through a contract to improve the operation of Spartan program; on November 3, 1977, Blue Spider project kicks off. The events in Blue Spider case are done in a quick manner in that there are a number of problems which arise right from the begging of the project because of the poor planning of the major events in the project.Amongst the results of the events is the poor communication in the various departments due to the overburden that is caused by Gary And erson; communication breakdown both internal as well as the departments which are associated with the project; the changes in the project are not well talked in advance. Despite the project going ahead, Lord industries accept the work of Parks Corporation reluctantly because of aviations from the requirements of the client due to changes in information and also implementation of the requirements. . 2 Objectives of the Report The aim of this report is to tie the systems engineering principles to the Blue Spider Case study. 1. 3 Organizational structure of Parks Corporation Figure : Parks Organizational Structure (sage & Rouse, 2011 : 80) 1. 4 SOOT Analysis of Blue Spider Project The current situation of the project is that it is influenced by a number of weakness as well as the strengths. Amongst the weakness of the Blue spider Project is thatAnderson was so much concerned with R & D works and also the administrative issues without creating any balance between them; there was a probl em in the financial planning; the project lacked a standby schedule which would have been important in the event that the formal was affected by certain changes; there was poor communication with the Lord since the start of the project which resulted to more costs on communication; additionally, it was not possible for Gary to find Gable the time when he need some form of assistance; however, Gable would intervene in the midst of the project a number of times without the knowledge of Gary that exulted to more issues in the project management; some of the issues included rescheduling of the project or redoing some works during the last times. On the other hand, there is lack of leadership skills demonstrated throughout this project. Both Gary Anderson and also Henry Gable show lack of leadership skills in the various tasks which they are involved in doing the work, poor delegation skills as well as lack of team effectiveness.Despite the weakness of this project, it is important to no te that the project had enough backing from the top executives and directors. It is to often easier to find a project which has enough backing from the management just like Blue Spider Project, the level of attention given to the project was high, and there were enough resources for the project which came from the functional team. Some of the projects in project management have failed simply because of lack of backing and also priority which has resulted to issues. 1. 5 Definition of the requirements The requirements of a customer as well as the constraints of a project constitute the input to a process. The requirements of a process are directly related to the performance metrics of a system that is being designed.The requirements often tell more about the needs of a customer in the system as well as the needs for the given system and they show clearly how the system is likely to work in the given environment. On the other hand, the constraints are some of the conditions which exis t in a system due to the effect of the external interfaces, the support of the project or the life cycle systems. The constraints affect the opportunities of the design team in achieving their objectives. The major focus of the system engineering is changing the requirements into design (Grammar et al 2011:77). The requirements or the Spartan program was that the technical specifications needed all the components to operate in a normal way and successfully in a temperature range of -65 degree F to a temperature of 145 degrees F.At the current time, the design of Parks Corporation was not able to operate over 130 degrees F. Despite this, one of the major constraints in the requirements was that the preliminary design material would not be operated over 130 degrees and this indicates that Gary Anderson and his technical team would not meet the set objectives. The requirements of a customer are very important in any design process; this is because they define the expectations of the cu stomer, the environment, the measures of effectiveness as well as the suitability of the system requirements. According to O'Leary, et al 2012:562), the process of defining the requirements of a system provides the initial step in the development of a system.However, in the Blue Spider case study, this is not given any meaningful importance with Gary Anderson and also Henry Gable conversing on the possible ways of changing the design material so that it would seem that they have followed the requirements of the customer. Henry Gable indicates that their reports would indicate that the design would be operative up to 155 degrees F so that the customer would be pleased something which was never true. This indicates that they both have failed to observe care in design process; this is likely to result to problems as this is likely to surface in the later stages of the life cycle of the Spartan program which will mean spending more time and also money in fixing these issues (Chandler et al 2011:375).From system design, specification requirements and testing, all were not done in the right manner with unethical behavior seen in in much of the design process. Figure 1, indicates the various requirements in a system, clearly the requirements are established within a system in order to ensure accuracy and also completeness. Serener (2013: 208) asserts that, it is always not easy to establish good requirements for a system since it needs effective communication and technical skills; the head of Spartan program Gary Enders on lacks the technical expertise to lead the project the reason why the start of the project faces a number of challenges with the requirements not done in the right manner and this made the implementation of the project to seem mixed up.Lack of ethical requirements are common in the project with Henry Gable stating that they can improvise the materials in order for the Spartan program to read 155 degrees F which is not the case as the customer would not know the improvises which the technical team would have done. 2. SE Management 2. 1 System engineering process According to Chandler et al (2011 :376), to ensure that a system is well engineered, it is important to conduct its development process in an orderly manner. Well-defined systems engineering process makes it possible to develop a system. However, for the gig projects, which involve a team, it is important to have a good systems engineering process (Coleman et al 2013:176). This is seen as guidance by the project participants to know the direction of the project and how they are going to achieve the objectives of a system.There is a common agreement amongst the engineers on the main steps in the software process. In figure 3, this is indicated, the initial steps indicate the process of solving a problem in feasibility study, the fourth step is defined as being post-development phase and this is the stage where the project is deployed to he users, where maintenance is don e and also improved to ensure that it meets the ever changing requirements. The initial steps of the process are often termed as being â€Å"what and how' in the software development while the â€Å"analyses and specify' step evaluates the problem which is to be solved while the â€Å"design and implement† provides information on how the problem is to be solved (SГ ¶Darlene 2011 :155).Figure : Systems engineering process Spartan program development process failed to pass through the right stages with several system engineering requirements not available in the different stages of the velveteen of Spartan program; this is vital so as to effectively achieve the customer requirements. The requirements of the customer were that the technical specification components were to operate in the normal way and in a successful manner through the temperature range of -65 degrees F to 145 degrees F. The analysis of the current system indicates that the design by Park Corporation is not likely to function at a temperature which is above 130 degrees F.Additionally, the requirements of the Spartan program were not well stated early on during the initial stages of the project; this explains the reason why the project is running into robbers at the early stages. One of the problems of the project is cost which should be defined and the budget of all the expenses prepared at the analysis stage when the problem is being defined to avoid any further expenses on the way which were not budgeted for. Gary Anderson should be the one who should be answerable to any of the problems which the projects runs into since he is the project manager; his lack of experience in handling projects is affecting the smooth flow of this project. 2. Development process Young (2013:113) states that development process indicates the procedure for evolving the various parts of a project; this helps the various persons involved in the project to identify the different issues early on in the p roject before the occurrence of bigger problems which would alter the smooth running of the project. The development process is vital in a project as it helps to guide a project which does not have well defined goals and objectives which the customers are unable to define on their own. Morris and Considered (2011:68) argue that development process of a project provides a way of getting feedback instead of planning as their main control mechanism. The feedback is as a result of more and more regular tests and also the releases related to the evolving software.In Blue Spider case study, the development process has failed and there are no consultations with the various departments in the preparation of the project proposal as well as consultation with the customer on their requirements. Although the customer's requirements for the Spartan Program are not followed and intentionally altered so as to suit how both Gary Anderson and Henry Gable want it to be; this is attributed to lack of technical expertise in the development process as well as unethical business behavior. . 3 Life cycle integration Frangipani (2011:390) states that, life cycle integration is the process of bringing together the existing systems as well as the new technologies to form a new system that performs more tasks provide more and improved performance as well as ensuring that they enhance the existing systems.According to Cravings (2011 :465), life cycle integration is seen as a way of using new as well as the expanded performance requirements in the most effective manner and also a timely manner during the design, the procurement, and installation and also in the operational infatuation that has specific modules where each of them may have some form of limitations and constraints. One of the major aims of the Blue Spider project was to ensure improved structural capabilities related to the Spartan missile which is a tactical missile made sue by the army. The missile was showing some form of fatigue in terms of failure after spending over six years in the field. The needs of the customer here were that they needed the new materials, which would last for longer for the Spartan missile.By providing new materials the new program would last for Eng and ensure improved performance and also making the present Spartan missile more effective. This is one of the major purposes of the life cycle integration where improving the present system is of utmost importance to the army (Marques et al 2011:1058). 3. Program Life cycle 3. 1 Generic Business Life cycle According to Fiction & Skimmer (2012:309), the increased importance of transition to a greater and sustainable economy presents one of the most challenging aspects of the society. While the evidence where developing a highly sustainable business model is related to great profits, it is a problem to majority of the conventional manufacturers.Because of this, firms are supposed to search for ways to improve the business models and in the process become more sustainable. Parks Corporation is always committed to developing new strategies so as to keep up with the changes in the market. The firm has performance criteria where the best and employees are promoted; the reason for Gary Andersen's promotion is because the firm is committed to developing a sustainable business model. Park Corp.. Seems to make use of the product-service system in order to relate to particular life cycle stage in the development of a project. The business model in Park Corp.. Involves marketing, he software engineering process, design, production and operation.Through marketing, Park corp.. Has been identified as one of the most successful firms in software engineering the reason why the Department of Defense (DoD) had several contracts with the firm. Stark (2011:10) notes that, software engineering is the next stage in the business life cycle with the firm making sure that the right project manager is in place to guide the developm ent of a project. Gary Anderson was chosen as the project manager who was to oversee the completion of the Spartan program; Gary was to oversee the design of the project, production as well as operation. 3. 2 Simulation of DoD acquisition policy Diagram 4. System engineering product 4. System Requirement review According to Blanchard (2012:66) the system requirements review is done after the end of the functional analysis as well as the preliminary requirements allocation to the hardware configuration items, the computer software configuration items, the facility configuration items as well as the personnel so as to determine the objective and progress related to the system engineering management. The items to be reviewed include the mission and requirement analysis, the human factor analysis, he mission and requirement analysis, the functional factor analysis, the program risk analysis and also specification development (Shall et al 2011: 556). Kiss-off et al (2011:98) state that, the requirements of a system fall in different categories.The customer requirement provide the statements or the facts as well as what the customer expects from the system in relation to achieving its set objectives, its effectiveness and also the suitability. One of the major requirements of the DoD contract was that the Spartan program was to operate normally and successfully on a temperature of -65 degrees F to 145 degrees F. However, the present design of the system indicated that the program would not function above 130 degrees F and this indicates that the objectives of the customer are to have the program operate at a temperature above 130 degree F. Despite the customer requirements stated clearly, the management in their proposal have developed a different system requirements which does not suite what the DoD want.Gary and Henry Gable intentionally meet to discuss the inability of the preliminary design material being operated above 130 degrees F as the customer want but the n because of lack of effective system acquirement analysis and accomplishment of the mission; they think of changing the design material or incorporate new materials and this problem has come as a result of poor system requirement review (Shall et al 2011 : 558). Another important factor in successful completion of a system is the human factor analysis. Stanton & Walker 2013:721) notes that despite the increase in technology, human factors are still vital to the success of a project. Thus effective interaction of human beings in the development of a project not only reduces the risk of project failure but also ensures hat the objectives of the customer have been met.Additionally, the use of human factors ensures improved safety, increased reliability as well as efficiency of the system. Despite the increased importance of human factors in a project, there seem to be a challenge in the Blue Spider project because of lack of human factors. The process of bidding never followed staffin g; one of the reasons provided is because Parks Corporation refused to give out its staff for the project; the engineering managers were not cooperative in giving out their key people towards the Blue Spider program. Human factors are important and should not be underestimated in successful project completion (Shall et al 2011: 558). Additionally, milestone is vital in the project completion (Adamant 2011:216).This state the important dates in a system which the client need to be updated on the progress of the system should be considered so as to ensure that the customer's requirements are well reviewed as the system keeps on being developed. Blue Spider project has successfully completed the first milestone of the project; the second milestone is scheduled to be after 180 days where acceptance of the raw materials and also the production runs ere considered; milestone is prepared in a way to avoid overlapping of activities in a system preparation something which Gary Anderson and h is team have done effectively in terms avoiding an overlap of the lab development and also the full scale production. 5.System engineering core process Schemas et al (2011:76) asserts that the system engineering major processes are developed so as to provide support to the people that are required to implement the systems engineering methodology. The core processes follow the following steps: provide an analysis, decomposition as well as allocation of the system requirements; litigation of the requirements of a system and management are important so as to ensure that the customer requirements have been met. Gary and Henry are making up important follow ups regarding the specifications of the system; despite the fact that Henry is imposing his own strategy in the initial phases of the program; the test matrix does seem to be a failure as the raw materials which the test result indicate do not seem to coincide with the particular specification requirements by the customer.This means t hat analysis of the requirements of the Spartan program is aced by ethical challenges as Henry is stating that the customer would not be aware of the trouble changes which they are about to make regarding the specification requirements for the program. Next is definition of the system behavior where the system's functionality as well as its operations is the major specifications at this stage. The functionality of Spartan program is well stated in the proposal by Gary team as well as the customer specification needs which is meant to improve the structural capabilities and also the age life related to the short range tactical missile.According to Apparel et al (2011 :120), the definition of the system architecture is important in the system engineering process; this includes defining the internal and external interfaces; the subsystems and the components of the system; although the specification of this contract by the customer (Army) was that the Spartan program missile was to be i mproved its structural capabilities; the project team led by Gary failed to define the system architecture of the project in their proposal to the Lord industries; the reason for this can be articulated to the inexperienced project anger who has not handled similar projects in the past and therefore thinks that projects can be done without even specifying their system components and subsystems.Marques et al (2011:1060) notes that, the most important systems engineering functions include operations concept development, architecture and the design development as well as identification of the requirements and management; however, these functions as well as the final products depend on one another. According to O'Leary, et al (2012:562), the system engineering functions, the validation, the prediction on performance, the analysis and trade off are important in optimization and development of a total system. In the system engineering life cycle, there is more refinement of the system req uirements, the design as well as the operations concept in the lower levels to a point where the design has been realized. After that verification and validation of the system requirements is done and also planning for the events and resources.Verification of the system requirements is done by both Henry Gable and Gary Anderson; however, their verification does not provide any importance to the success of this project as the customer requirements re ignored, making them to think of ways of devising the performance of the Spartan program missile to operate at a temperature of 130 degrees F. The events and also resources in Blue Spider project have not been planned well; despite that the project does not meet the planned milestone and this is because of the inexperience of Gary Anderson as he is left to do most of the work by himself to beat the deadline; the case indicates that Gary did not want to overburden the staff with the responsibility of the handouts and because of this he di d this by himself, the reason why the reject does not have enough resources is because of lack of planning for the events and resources and hence putting in place the necessary budget for the same and this has resulted to cost overrun.The system engineering is important so as to handle the challenges which the system engineers face during system development (Meredith & Mantel 2011:155). 6. System engineering process implementation 6. 1 Events where System Engineering was needed According to Apparel (2011 :130), the use of different engineering tools as well as the safety analysis tools is important during the design process. This is important as it ivies the designers an opportunity to identify the dangers in the early stages of the design process and this is the place when they are easily worked on. The use of system engineering would be possible in the analysis of customer requirements; this will translate the requirements if the customer into both functional and also the design p arameters.Both Gary Anderson and Henry Gable are contemplating on how to fix the materials so as to ensure that the Spartan program is operating at a temperature above 130 degrees F; something which the matrix test failed to produce the required raw materials. Additionally, functional requirements of the Spartan program are not identified early on at the start of the system planning, design and also the development phases; the result is failure to meet the system milestone. The important safety system requirements were not included in the Spartan program including the system-level safety analysis. 6. 2 Consequence of lack of system engineering Lack of system engineering in the Blue Spider project has resulted to a number of challenges in the development and completion of the project.Key stages have been omitted and this has affected the achievement of customer requirements; the customer has complained about the materials included in the proposal which seem to contract with their req uirement on how the system should be and how it should operate. It is worth to note that systems engineering is often implemented by coordination in the design engineering, effective architecture development as well as the design which are able to ensure that they meet the needs of the customer. Gary and Henry are unable to satisfy the needs of the customer in the Blue Spider project because they failed to in the use of system engineering principles during the design s well as systems requirement specification.Blue Spider project headed by Gary Anderson has failed in the systems engineering as well as in the operations concept which failed to reflect the objectives of the Spartan program customer (the Army) as well as failing to schedule the project within the set budget. 6. 3 How to Implement Systems Engineering One of the objectives of systems engineering implementation is the full-integrated development as well as making products, which meet the needs of the customer within speci fied cost, schedule and also the risk constraints (Apparel et al 2011 :152). Therefore, this implies that a project needs to give a structured process for effective integration and link the requirements well, the schedule, the decision milestone and also validation and verification.However, this is not the case in Blue Spider project as the project team lacks the needed cooperation to ensure that the implementation objectives are met as well as the systems engineering process. Gary Anderson is forced to do majority of the scheduled tasks in order to avoid expenses, which would mean that the project would not meet the set budget and hence the implementation of the system was a problem. Not all the departments are involved in the various phases of the project; the project team often needs to work on a â€Å"single, integrated set of requirements and also process† which mean that the integration of the system requirements and also the design stages will reduce the cost; a challe nge being faced by Gary Anderson as the project cost is going high.Additionally, effective implementation means that it is vital to lower the unplanned as well as the cost of reengineering that is important in solving the â€Å"omissions and challenges in integration†. 6. 4 Events where Systems Engineering were present Despite the challenges which the Gary Anderson and Henry Gable faced in the Blue Spider project, the use of systems engineering were present in the formation management of the software development project more so in the planning of the project, estimating the cost (budget), formation of the project team, allocation of work for the members of the team, the work schedule plan, reviewing of the progress of the project and also reporting the project's milestone.All these activities used the system engineering concept despite a few challenges. 6. 5 Benefits Davenport (2013:118), states that, systems engineering is important as it ensures that reduces which match the challenges of the global market are produced; it is clear that customers need a higher range of products and the choice which need that firms are supposed to produce products which match the customer needs; thus systems engineering helps firms to ensure that this objective is achieved. Systems engineering provides a way of ensuring that customer objectives are achieved and also the best way of achieving the market leadership by producing the best products in the market with good quality. 6. Comparison It is clear from the case study that concepts of design principles, specification acquirement, and risk management never made use of the system engineering principles, the reason why Gary Anderson and Henry Gable are faced with challenges of meeting the customer needs. 7. Systems Engineering Planning 7. 1 Project management Plan Marques and Laura (2011:1061) states that, project management plan involves organization, the relationship involved in reporting, the decision process as well as the role of the management committee in ensuring the success of the project. It shows the amount of time which the project manager is likely to spend in the project management. Therefore, the project team members should be written down as well as the details of the contact and any changes communicated to the program manager; the project need to state whether there is any need for training.Gary Anderson is involved in majority of the work the reason why most of the plans are behind schedule. The decision by Gary to lower the costs through accepting to work on the bill of materials by himself indicates that there is lack of project management plan for the project; scheduling and making sure that all activities are accomplished thin the stipulated time is important to effectiveness of system engineering. 7. 3 System engineering plan According to Adamant et al (2011 :21 5), System engineering plan is a major activity that has an effect on the acquisition planning decision and as a r esult develops important methods which will be effective in achieving the objectives of acquisition.This is important in the systems management in assuring of the technical activities' identification and their management; ensure that the technical approach in the development team has been communicated, ensure that there is technical implementation and that decisions have been documented and finally help in establishing the benchmark of system development which is vital in meeting the needs of the customer and that of the systems engineering as well. Systems engineering plan has been followed in the Spartan program development; plans are put in place as Gary Anderson is appointed as the project manager with various persons involved in the development team; however, this is not done to satisfactory and this is because of lack of proper system engineering plan, the engineering integration distances themselves on the preparation of the bill of materials because

Response to a Graduation Speech Essay

E. Goldson, (2010) wrote a valedictorian address, â€Å"Here I Stand†, a speech dedicated to explain that too much concentration and effort towards memorization and following directions can hinder or distract creativity and the general learning processes.. Goldson describes the educational experience as an uneventful routine Goldson (2010) stated, â€Å"Perhaps, you only learned how to memorize names, places and dates to later on forget in order to clear your mind for the next test. School is not all that it can be.† Goldson (2010) moves on with her speech belittling her own accomplishments by stating, â€Å"I cannot say that I am any more intelligent than my peers. I can attest that I am only the best at doing what I am told and working the system.† There has to be more to life than a dull routine of going to school, following all directions, and then preparing to work. This sort of depressing picture is usually painted by a negative attitude. However, Goldson proves to have a superior attitude in order for her to gain the position of being top of her class. Goldson shows real talent in her creative writing, unless someone else wrote this speech for her. She must have a more probable reason to belittle her own achievements. One trap some teenagers of high school fall into is displaying a vain or conceited demeanor. Goldson most probably wanted to gain respect from her audience by presenting a humble tone to avoid being accused of thinking of herself as being better than everyone else. Also, most high school students love to show contempt once in a while just to have an outlet of the stress associated with a high school crowded with students many of whom do not want to be there.. This speech definitely shows rebelliousness against the structure of our education system. This criticism of our educational system appeals to the rebel student in her audience. Who can deny that the system is not perfect and that there is always room for improvement? However, Goldson’s speech does not offer any solutions to help improve the system. She does not appreciate her own writing skills, reading comprehension, math abilities and good memory. All of these attributes Goldson gained by following directions and doing extra credit can actually enhance new ideas, inspire creativity and open many opportunities. Think of all the scholarships Goldson could take advantage of. Her grades alone qualify her for the most prestigious universities. The only reference Goldson (2010) used to back up her claim was a hypothetical conversation between a Zen student and master. There is no proof this conversation took place, and so it is most likely to be fictitious. The simple truth of the matter remains; that several highly educated people have proven that Godson’s argument is outright weak. People in real life have proven beyond any doubt that education does now, and has in the past; inspired new ideas. John F. Kennedy, for example, graduated from Choate (high school) in 1935. He graduated Harvard University in 1940. Martin Luther King Jr. shows tremendous credit to Yonge Street Elementary School, and Booker T. Washington High School: because of his high score on the college entrance examinations in his junior year of high school, he advanced to Morehouse College without formal graduation from Booker T. Washington. Having skipped both the ninth and twelfth grades, Dr. King entered Morehouse at the age of fifteen. From there he then received his Bachelor of Arts degree from Morehouse College in 1948 at age 19 and his Bachelor of Divinity degree in 1951 from Crozer Theological Seminary and Ph.D. from Boston University in 1955. Goldson failed to recognize the opportunities she had well earned from her experience in Athens high school. It was most likely due to her low esteem that Goldson failed to recogonize the skills and abilities learned from her hard work and dedication in Athens High School. She did, after all, bring discredit to achieving the top of her own class of 2010. References Goldson E.

Drama Analysis Essay

In preparing to write my drama-analysis research paper, I encountered a wealth of information regarding my topic: The Pursuit of Happyness, a film which I believe demonstrates a return to â€Å"classic† movie-making and also a return to film as inspiration rather than lamentation. In my essay, I argued that, despite certain flaws and tendencies to revision historical relaity, The Pursuit of Happyness is a great film , and potentially one of the most important American films. Arriving at this conclusion was a long and interesting road, which was partially established by the research and writing of the paper itself. However, I felt determining my opinions and reinforcing them with information from my research materials was much easier than organizing the paper and expressing my opinions in solid, correctly constructed writing. One approach that I thought would be workable, but which proved to be merely frustrating, was to draw primarily from my own experience and opinions about movies. In my original intention for the paper, I had imagined that I would contrast The Pursuit of Happyness with other films I had seen and contrast, also, the way these various movies made me feel and also what I may have thought about their technical aspects. When I tried to use these kinds of comparisons in the actual research paper, I felt like what had been so obvious to me, as a subjective movie viewer, would be very hard for others to identify with, unless I expended a tremendous amount of space and energy to explain my personal tastes and opinions. What seemed to work better than the inclusion of my extended opinions was the citation of otehrs’ opinions. There seemed to be two advantages in citing material which supported my opinions rather than merely offering my opinions themselves. the first advantage was that i found certain writers expressed my thoughts and ideas just as I would have liked to express them myself. However, because the writers of the articles and essays I cited were professionals, their words were much more succinct and precise than some of my own attempts at saying the same thing. The second benefit of using cited materials was that some of the opinions I cited were, in fact, slightly different â€Å"takes† on opinions of mine, and I don’t think i would have necessarily come to understand these slight variations without having done the research. So, rather than merely supporting my opinions, the research materials actually modified my opinions and sometimes reinforced them very nicely. I felt more confident and determined in my own thesis because I knew authoritative writers from The Wall Street Journal and other professional publications supported some of my views. The only real obstacle I faced with research was whittling down the enormous amount of available information. I think the Internet has made it easier to conduct wide-ranging research quickly, but that in itself makes it much more difficult to sift through all of the available information and pinpoint what will be useful in support of the research paper in question and its thesis. Defining my thesis itself was also challenging. The more I thought about stating my argument simply and directly in a single sentence or a couple of sentences, the less the whole idea seemed meaningful at all. I learned as I continued to work at defining my thesis that it is important to get everything set in a single direction. I’m not sure if I was actually successful in presenting a sharp, simple thesis, but I tried very hard, Essentially, I wanted to show that The Pursuit of Happyness is a good film and one which also returns film-making to a role which it has steadily abandoned over the years in America: that of inspiring people. I believed that the thesis statement is true and feel it is true,. but I found that making my points in writing and spelling them out logically, as well as addressing counter-arguments forced me to reconsider my solidly constructed beliefs. Even though my overall opinions did not change very much, my respect for the logical formation of written arguments grew steadily as I worked on my own paper. Just as it is important to think simply in many way to secure a good thesis for a research paper, it seems important tow rite simply, as well. That is, I think it is important to stay on topic and make your argument point by point rather than digressing or getting too far off of track, no matter how tempting it is to launch into extra thoughts and associations. Even paragraph by paragraph, I think, all of the sentences should be necessary and feed into one another. I wasn’t as aware of this fact before spending time on the drama-analysis research paper. In addition to learning valuable steps and techniques for writing and thinking, the process of writing the paper caused me to re-examine the methods or logic by which I arrive at my opinions in the first place. I think that;s the most important thing I leaned in composing my research paper: that the logic and â€Å"formal† thought that goes into writing a good research paper differs widely from the â€Å"looser† thoughts and associations which typically help define at least my own subjective opinions. I’m not sure IO was aware of just how different my â€Å"everyday† thoughts and logic were from those which are necessary to present a clear, convincing argument which is backed up by solid evidence. In the long run, I feel certain that I could now make, as a consequence of my experience in writing the research paper, a much stronger argument on behalf of my original opinions.

Historical Biography of Archimedes

The presented text is a summary biography of Archimedes of Syracuse. Known as one of the greatest mathematician, scientist, and inventor; Archimedes’ notoriety has been maintained over centuries by the scientific discoveries and technological inventions he brought during his lifetime. This text relates of his many accomplishments in a semi-chronological order, in attempting to retrace the marking facts of Archimedes’ life. Archimedes was born in 287BC in Syracuse, Sicily. He was the son of astronomer Phidias (Crystalinks, 2008). Presently, there is no information specifying of the work accomplished by Phidias.Similarly, there is little detailed information concerning Archimedes life as a child and adolescent. According to history, Heracliedes wrote a biography of Archimedes which is subjected to have had detailed information about various aspects of Archimedes private life. Unfortunately, the biography was destroyed and many aspects of Archimedes personal were lost in t he process. It seems that the span of the years has erased the memories of his childhood upbringing. In fact so little is known of his personal life, that there exists no specifics on his coupled life. Whether he had a wife and children remains unknown to the present day.In comparison, his professional adult life has been studied and retraced century after century, relating of his incredible prowess with Mathematics, and of its unusual genius for technological inventions; some of which are still being used today, two millennia after his death. Historical texts mention his relation to King Hiero II, then the King of Syracuse and presumed uncle of Archimedes (Crystalinks, 2008). The validity of this relation to the Royal Family of Syracuse comes again and again in writings concerning Archimedes, and the few elements of his young adult life seem to confirm his privileged ranking in Syracusian society.In fact, Archimedes was schooled in Alexandria, Egypt where he traveled to as a teenag er to study mathematics (University of St Andrews, 1999). The many counts of his spectacular professional life as a mathematician, scientist, and inventor seem to retrace an origin to that period of his life. Certainly the ability to pursue university study confirms of his family ties to the Aristocratic society of Syracuse. He would later in his life collaborate closely with King Hiero II to come up with inventions to prevent Roman invasion of Syracuse.Some of those inventions of warfare are reviewed in further detail in the portion of this text dedicated to Archimedes technological inventions and innovations. Archimedes began study in Alexandria at the age of 18. He was then brought to study mathematics along with Conon of Samos, and Eratosthenes (Crystalinks, 2008). As a scholar in Alexandria, he was allowed to study both the theoretical and practical aspects of science and technology, that he often retransmitted back to Greece via letters of correspondence he wrote. It is believ ed that Archimedes spent five to six years in Alexandria at study.There are no other accounts during the life of Archimedes where he would have spent a comparable amount of time being educated in the formal sense. Following his study, he returned to Syracuse to become one of the most prolific scientist and inventors known to mankind. History tells that Archimedes invented the Archimedes screw while at study in Alexandria. The famous screw used to carry water from a low lying position to a higher position would found many useful applications and is presently used in modern day sewage plants. An amazing feat indeed.His ingenuity continued after he returned home to Syracuse, and was fueled by the desire to find adequate solutions in order to protect the city from Roman invasion. In fact, often under the demand of the King, he undertook and completed several inventions targeted at warfare. For so doing, he used mechanisms of destruction and others of dissuasion that proved efficient as they held the roman invader, General Marcus Claudius Marcellus, from entering the city of Syracuse for two consecutive years. Archimedes died in 212BC, while Syracuse was under siege by the Roman invaders.The story tells that he was killed by a roman soldier during the attack of Syracuse (Crystalinks, 2008). His mathematical Genius Archimedes of Syracuse is particularly known the world over for his stunning ability with mathematics, and in particular with geometry. In this section of the biography, we are to retrace the most important theorems he came up with, and relate of his most impressive scientific discoveries. On the contrary to most mathematicians, Archimedes mathematical inspirations often came from his work on Mechanics, thereby suggesting of an influence he brought to mathematics by making hypothesis based in the practical world.This is a very interesting practice which is peculiar and certainly differentiates his work from other mathematicians who mostly would come up wi th a mathematical theorem and then attempt to verify it in the physical world. Archimedes wrote extensively on his work, although most of his work vanished over the years. In particular, he wrote a treatise on mechanics and hydrostatics entitled the â€Å"Method Concerning Mechanical Theorems†, which according to history often inspired his work as a mathematician. As he seemed to find his inspiration in the physical mechanical world, Archimedes excelled in the field of Geometry.One of his famous discoveries was in relation to the comparable volume of a sphere and that of a cylinder. Archimedes was able to prove that the volume of a sphere equaled two-thirds of the volume of a cylinder for which the height equaled the diameter of the sphere (University of St Andrews, 1999). Archimedes was so proud for having found that mathematical reality that he insisted on having it carve on his tomb. Although Archimedes is often thought of as more of an inventor than a mathematician, he pa rticipated in several key developments in mathematics.Archimedes often made use of infinitesimal sums to arrive at proving his hypotheses (Crystalinks, 2008). The method is often compared to modern day integral calculus which is very similar to the methods he employed then. One of his famous mathematical proofs was the approximation of Pi. Archimedes often used his ingenious notion of the mechanical world to arrive at more conclusive mathematical realities. In order to estimate the value of pi more accurately, he designed a circle. He placed a polygon on the outside and on the inside of the circle (University of Utah, 1999).As he would raise the number of sides of each polygon, he came closer and closer to having a circle; effectively made of a series of small and connecting distances. As he reached 96 sides for the inner and outer polygons, he measured them to obtain a higher and lower boundary limit of the approximation of Pi. Archimedes concluded from the experiment that the valu e of pi was contained between 3+1/7 and 3+10/71 (Crystalinks, 2008). A remarkable feat leading to an impressive conclusion, which we consider today one of the most important proofs of mathematics.The formula for the area of a circle is also attributed to Archimedes who came up with the fact that the area was equal to the square root of the radius of the circle multiplied by Pi. His interest for arriving at mathematical truths based on geometrical realities as we can perceived them in a multi-dimensional system, led him to prove more theorems often relating to infinite series or infinite sums. Archimedes is known for determining the equivalency of certain rational numbers by determining their infinite sum.A rational number differentiates itself from a whole number (an integer for instance), as it has an integer portion and a decimal portion. The infinite sum approximation is often used in mathematics today to estimate areas and volumes in two dimensional and three dimensional spaces primarily. The technique he employed in his infinitesimal related theorems are commonly called method of exhaustion in modern day mathematics (University of St Andrews, 1999). As impressive as his ability for arriving at mathematical reality was, it made even more physical sense when he applied it to the physical world in which we live.Many of Archimedes theories relating to physics are closely relating to the fields of geometry and physics in general. Often the geometrical mystique of an object would eventually lead to a physical mathematical reality of our world. It is seemingly in such proceeding that Archimedes came up with several theorems of mechanical nature. In fact, Archimedes discovered several theorems on the center of gravity of planes, and solids, and on the mathematical tools and methods to approximate those.It is interesting to mention that his work, whether in theory or practice was often commanded by the search of the infinite in the mundane reality of the finite. A rchimedes is known to have worked on the mathematical theories of spirals, where he helped to determine the mathematical formulation to describe spirals based on polar geometry. The work was compiled in a treatise called the Archimedean Spiral. The treatise describes in mathematical terms the function of a point moving away from a fixed coordinate at a constant speed and with constant angular velocity.The function described in the treatise corresponds to the geographical representation of a spiral, which in the treatise is the result of moving set of points in a given pattern, that of a spiral (University of St Andrews, 1999). Several of his written theoretical work came as correspondence letters, in particular to a person of the name of Dositheus, who was a student of Conon (Crystalinks, 2008). In some of his letters, Archimedes referred to the calculation of the area enclosed in a parabola and determined by a line secant to the parabolic curve.In the letters to Dositheus, Archimed es was able to prove that such area would equal to four thirds the area of an isosceles triangle having for base and height the magnitude of the intersecting line in the parabola. He arrived at the result using an infinite summation of the rational number one fourth. This particular mathematical demonstration would later prove invaluable in calculating the areas and volumes of various objects in using integral calculus, a modern form of Archimedes infinite expansion.One of his most famous scientific discoveries relates to the buoyancy effect of a liquid on a given object: often referred to as Archimedes’ principle. The principle explains that any body immersed in a fluid experiences a force of buoyancy which is equal to the magnitude of the equivalent gravitational force of the liquid displaced during immersion. In other words, Archimedes arrived at the reality that any object plunged in a liquid plentiful enough to maintain such object in equilibrium, would experiment a forc e in reality equal to the body of water displaced to maintain such equilibrium.There is a famous anecdote on how Archimedes came up with the physical theorem. Legend has it that it was during a bath that he came up with the concept for the buoyancy theorem. According to history, he came up with the answer to the buoyancy theorem in wanting to help his uncle, King Hiero II, to solve the Golden Crown Mystery. In fact, the story relates that the King, Hiero II, sent a certain amount of gold to his goldsmith to be made into a crown. When the crown returned from the goldsmith, the King apparently noticed that it was lighter than the presumed amount of gold that was given to the goldsmith.King Hiero II presented the dilemma to his nephew Archimedes of Syracuse, who supposedly came up with an answer to the problem that very night. The legend states that Archimedes came up with the buoyancy theorem by filling his bathtub to the top. When he entered the bath, a certain amount of water poured out of the bath. He later on realized that the mass of the amount of water dispersed from the bathtub was equivalent to the mass of his own body. From arriving at this discovery, the story claims that Archimedes ran the streets of Syracuse naked and screaming â€Å"Eureka†, which means â€Å"I have found it†.The next day he reiterated the experiment with the Golden Crown and the same amount of gold that was initially given to the goldsmith, when he was able to confirm King Hiero’s assumption that not all the gold given to the goldsmith was used in making the Golden Crown (Andrews University, 1998). This amazingly simple proof carries one of the most important theoretical truths of physics. The principle of buoyancy is better known today as the Law of Hydrostatics, and is directly attributed to Archimedes of Syracuse.The above anecdote is a classic example of Archimedes’ability to confront complex theoretical problems by transcribing them into practical l ife. A considerable number of his experiments and scientific theorems were similarly found through empirical and methodical practical proceedings. Archimedes Inventions As a keen mathematician, Archimedes was particularly talented in determining physical solutions to various problems encountered in his life. Often, the mechanical tools that he devised were a direct projection of a theorem he wanted to prove or vice versa. One of his most famous inventions was the Archimedes screw.Sometimes referred to as Archimedes water pump, the device was created by the Greek mathematician during his study in Alexandria. Archimedes screw is a machine made to pump water from a lower level to a higher level. In short, an ingenious method for carrying water over distances thereby apparently defeating the law of gravity. The screw is made of a cylindrical pipe angled at fourty five degrees and containing a helix. When the bottom end of the device is plunged into water and set to rotate, the helixâ₠¬â„¢s rotation carries water from the bottom end of the cylinder to the top end (Crystalinks, 2008).Archimedes according to historians, devised another form of the screw in a comparable yet dissimilar shape. In our day, the system is being used primarily in waste-water treatment plants to pump sewage waters. There is little account however on the applications for which the Archimedes screw may have served during Archimedes life, other than its use for irrigation of the Hanging Gardens of Babylon, and for removing water in the hull of ships. In fact, most counts of using the technique point to its modern day utilization.Other inventions brought by Archimedes received a considerable amount of attention, and found direct applications during his lifetime. From his close relationship with the King Hiero II, Archimedes was requested to build machines to keep the Roman assailant at bay. Archimedes successfully created several weapons of war that held the Roman invader several years. Archim edes is in fact known for inventing the catapult for that purpose. The catapult is a device based on the principle of the lever, which is capable of carrying an object several times its weight.When the catapult is fired, the object â€Å"flies† in describing a parabolic curve, prior to hitting its target. The catapult was often used during warfare as a defensive method to protect a territory from invaders. He would later on be used as on offensive weapon for attacking protected areas or castles. The catapult can be assimilated as the early form of a canon, which solely relied on mechanical means to operate. The device served Syracuse of Sicily well during the Punic wars of Rome vs. Carthage. Archimedes, at the King’s request, created several weapons to defend the city (Biography Shelf, 2008).Among such weapons were the catapult, the crossbow, and the claw; which could be used to cover several ranges. These various methods of defense allowed Archimedes to keep the Roman assailants at shore for two long years, according to historical reports. Archimedes also came up with the Archimedes ray, a device which was created to set invading ships on fire at a large distance. The device is made up of several mirrors forming a parabolic shape where the rays are reflected to subsequently interfere at a point which can be considered the focus of the parabolic shape.By aligning the mirrors adequately, it was then feasible to set ships on fire by focusing light reflected from the mirrors directly onto the ships. However, not all of Archimedes inventions were meant for warfare. The Greek mathematician and inventor came up with several devices to assist sailors to carry large objects from the water. Most of those devices operated based on the principle of the lever that was also used in the conception of the catapult. Off all of his work both in theory and in practice, only his writing remained to this day.In fact several of his correspondence letters were compile d into a repository of treatise commonly called the Archimedean Palimpsest (Cryslalinks 2008). According to ancient history, a palimpsest is a literal compilation of writings that were transcribed onto parchments and contained several layers of text on a given page. It seems evident to modern day historians and archeologists that the multiple writings on a single page indicated that parchment were expensive and hard to come by, and thus demanded that the author writes several times on the same page in order to conserve the precious parchment.The Archimedean palimpsest was made of the following treatises: 1- On the Equilibrium of Planes The treatise was focused on the principle of the lever and its various applications. The document describes how the principle of the lever can be applied to the calculation of the center of gravity of various bodies including parabola, hemispheres, and triangles. 2- On spirals The treatise â€Å"On Spirals† describes the mathematical function o f point moving in a curvilinear direction in a three dimensional setting. The work is better known under the appellation of the Archimedean Spiral. 3- On the Sphere and the CylinderThe treatise describes the mathematical derivation on the relationship between a given sphere and a cylinder having for height the diameter of the sphere. Archimedes was able to mathematically prove that in that very context, the volume of the sphere equaled two thirds to that of the cylinder. 4- On Conoids and Spheroids In this treatise, Archimedes demonstrates how to calculate the areas and volumes of conical sections, spherical sections, and parabolic sections. 5- On Floating Bodies Probably one of the most famous works of Archimedes, the â€Å"On Floating Bodies† treatise describes the theorem of equilibrium of fluidic materials.In this document, Archimedes proved that a body of water would take a spherical form around a given center of gravity. In the second volume of the treatise, he describe s the equilibrium states of parabolic sections partially immersed in a body of water. 6- The Quadrature of the Parabola This treatise corresponds to the mathematical derivation that the area made by the intersection of a line with a parabola equals four thirds of a triangle having a base and height both equal to the segment of the line intersecting the parabola. 7- StomachionThe treatise describes a problem in which Archimedes attempted to estimate the number of strips of paper of various shapes and quantities that would be necessary to reconstruct a square. The method is said to be an early version of the field of combinatorics. The Archimedean palimpsest was conserved over two millennia, and his now conserved at the Walters Art Museum in Baltimore, MD. It is the only remaining work directly written by Archimedes himself to be existing today. Unlike the mathematician’s writings which were compiled in the Archimedean palimpsest, there are apparently no remains or originals of his practical inventions.The Archimedean palimpsest is direct testimony of Archimedes’ inclination for mathematical prowess, in particular when it concerned geometry. Most of his work that was conserved in the redaction of the palimpsest describes some very important rules and theorems for Mathematics. Among those, the approximation of pi and the use of the method of exhaustion to estimate areas, volumes, and surface areas of solids of varying forms were key elements leading to modern day mathematical practice.Some of his inventions are in use today, yet his name is most often associated in our era with the buoyancy theorem also known as Archimede’s Principle.

Physical Chemistry - Essay Example This motivated John Dalton to study what makes different reactions unique. John Dalton, in his childhood years was educated by his father, and a man who managed a private school, called John Fletcher. He gained a wide understanding of science from the unofficial tutoring by  John Gough. At age 27 he was appointed to teach mathematics and  natural philosophy  at the  New College  where he taught for 7 years (Emery, 1988). Dalton formulated the theory after carrying out experiments into the behaviour of various gases. These experiments were based on 2 laws. The first was the law of  conservation of mass (by Antoine Lavoisier) that posits that the overall mass in a chemical process does not change (Dial, et al., 2009). The next law was the  law of definite proportions (by Joseph Proust) that posits that when a compound is stripped into its basic elements the masses of the basic elements will have similar quantities, irrespective of the amount of the original material. As a follow-up to the experiment conducted by Proust on oxides of tin, John Dalton conducted the same experiment on the oxides of tin. He also experimented with water and how it absorbed carbon dioxide and nitrogen. Dalton also started the study of various atomic weights depending on the combinations of the mass proportions, while taking the hydrogen atom as the base standard.   From the laws Dalton established the  law of multiple proportions that posits that when 2 chemical elements combine to produce more than one likely compound then the proportion of the second element’s mass that joined with a specific mass of the first element will be represented as proportions of whole numbers (Niaz, 2001). The results of this laid the foundation for Dalton’s Atomic Laws. These are made up of five theorems. The first theorem posits that an element, in its unmixed state, is made up of particles referred to as atoms. The second posits that all the atoms in

Wal-Mart to open new Super center in Tarpon Springs, Florida - Essay Example Wal-Mart has been one of the most profitable companies in the world, yet a growing movement among local citizens and leaders could cost the company valuable time, extensive legal fees, and a potential boycott among the locals in this traditional small city. Despite working with local and state officials in acquiring the proper zoning and building permits, Wal-Mart has faced an unexpected obstacle. Known as the U.S. base for the Greek-Orthodox religion, and a quaint area known for its exquisite sponges, traditional sponge-divers, and small Greek shops and restaurant, Tarpon Springs has amassed a unique culture. So, when Wal-Mart announced in 2004, that it was opening a Super center, opponents lined up to try to stop it. Armed with a piece of restrictive growth legislation titled "Statute 163," the non-profit citizens' group, Concerned Citizens, has raised tens of thousands of dollars to block the expansion. By February 1, 2006 this group has spent over $100,000 in legal expensesiii. Headed by the umbrellas organization, Friends of the Anclote River, and founders, Helen and William Gladwin, citizens' groups continue to fight and have placed the Tarpon Springs City Council in an uncomfortable positioniv.
