Marketing and Different Vendors Essay Example for Free

Marketing and Different Vendors Essay Having multi-vendor partnerships has its advantages and disadvantages. In the long run, supporting such a partnership would be difficult to maintain. Here are some of the concerns: * Change: Hardware and software requires constant upgrades to keep up with the technology changes. Changes in systems from multiple vendors can cause integration problems and requires a rigid process of testing and configuration. * Knowledge: IT staff must be well-trained in all the systems of the multi-vendor environment. Without a good IT support, the harder it is to find the source of the problem, and the longer it takes for them to resolve it. * Communication: In-house IT staff may have all the knowledge on the systems in the multi-vendor environment, but sometimes support from the vendors is required. In such cases, a support engineer is required to communicate with other support engineer, and it would be easier if it is done within the organization, but this is not usually the case. . Focusing IT on top line requires bringing in revenue for the company by increasing sales, whereas focusing IT on the bottom line requires bringing the cost down by reducing on operating cost. Focusing IT on the top line is more challenging because IT is not able to control who and when someone will actually buy the products and services. On the other hand, focusing IT on the bottom line can be predictable as there are sets of parameters within he organization that can be controlled, for example, reducing the number of employees. 3. Some ways for IT to bring in revenue is by increasing the number of customers and retaining customers. To increase the number of customers, IT systems such as online marketing tools can help to generate sales leads and increase customer awareness by sending out emails or direct mailers to potential customers. Such tools can help in segmenting customer profiles and evaluate the performance of the marketing campaign.

How Close The Schlieffen Plan Came To Success

How Close The Schlieffen Plan Came To Success The  Schlieffen Plan was a strategic plan produced by the  German General Staff in the early 20th century. The plan was designed to deal with the threat of encirclement, as Germany had France  to the west and  Russia  to the east. The plan was put into action during the opening of The  First World War  in which Germany had to fight on both a  Western Front  and an  Eastern Front. The plan was designed to take advantage of the difference in time that it would take each of the three countries to mobilise for war. The thinking behind the plan was for Germany to avoid a  two front war  by focusing their armies in the west, quickly defeating the French forces as they had done in the franco-prussian war and then to move its armies using its internal rail network to the east, to deal with the Russian forces before they had time to mobilize fully. The Schlieffen Plan was created by Count  Alfred von Schlieffen  and modified by  Helmuth von Moltke the Younger   after Schlieffens retirement (1). The plan was actually used by Moltke, and, in its modified form, was executed to near victory in the first months of the First World War. However several factors, including the modifications to the original plan; a French counterattack on the outskirts of  Paris  (the  Battle of the Marne); and surprisingly speedy Russian offensives, prevented the plan from reaching its conclusion, thus ending the German offensive, and resulting in prolonged  trench warfare. After the  Franco-Prussian War  of 1870, the province of  Alsace-Lorraine, which had been French and contained a mixed population of French and Germans, had become part of the  German Empire. France was clearly eager to regain its lost territory. However because of  Bismarcks alliances, (2) France was unable to threaten Germany, once  Kaiser Wilhelm II  took the throne in 1888 he began to let the alliances slip and German leaders began to fear encirclement. The first element of the plan involved Germany quickly deploying its forces as well as ignoring the neutrality of  Luxembourg, Belgium  and the Netherlands. The strategic element of the plan was the powerful German right wing moving southwest through Belgium and Northern France, letting the last man on the right, brush the Channel with his sleeve,  in the words of Schlieffen (2), while maintaining only a defensive posture on the central and left wings, in  Lorraine, the  Vosges, and the  Moselle. As previously mentioned, Russian mobilization was thought to take around six weeks, this time was largely due to Russias poor rail network. Therefore after France was defeated within the scheduled forty two days, German high command  would transfer the bulk of the German army to the  Eastern Front. The plan initially deployed 91% of the German troops to France and only 9% to Russia. The goal was to overwhelm France in six weeks, (the time it took for Russia to mobilize its army), and turn back to the Eastern Front before Russia was fully prepared for war. Kaiser Wilhelm II is quoted as having said Paris for lunch, dinner at St. Petersburg.(7) However the German offensive was not successful and we can identify seven major reasons that the Schlieffen Plan failed these are: The effectiveness of the  British Expeditionary Force: The British Expeditionary Force (BEF) was small compared to the vast armies being mobilised by France and German the total number of Tommys was only 75,000 at the beginning of the war. The French amassed millions of troops, and their aim was to use this number to push the German invasion back quickly and retake  Alsace. To this end, the French commander-in-chief  Joseph Joffre  deployed the small but highly professional BEF on the left flank, where it was thought that there would be no combat. However because of the spped at which the German forces advanced through Belgium, the British were nearly routed several times (3), but they managed to hold-up the Germans long enough for French and British reinforcements to arrive. While the BEF was forced to draw back throughout the month of August, it provided enough resistance against the  German First Army  under  Alexander von Kluck  to help encourage the German general to break off the Plan. Instead, von Kluck turned south- east towards  Compià ¨gne, showing his flank to the Garrison of Paris under  Gallieni, making possible the Miracle of the Marne. (5) The speed of Russian mobilization: The Russians moved faster than anyone expected, taking ground in  Eastern Germany  far quicker than the Germans had thought possible. While the initial Russian invasion was little more than harassment, had the Germans not moved forces to check them they would have come dangerously close to  Berlin. To prevent this Germans moved more troops from the western front to the east. This However was unnecessary and counterproductive as while the forces moved away from the Western Front were still being transported the  German forces in the east won the victory at Tannenberg in early September 1914, while at the same time battles on the Western front were going badly for Germany.(6) The French railway system: Because the Germans had been held up by the British and Belgians, the French had more time to organise and transport troops from the border to Alsace-Lorraine. The Germans had not accounted for how quickly the French would be able to do this, This resulted in the Germans encountering a very differently organised French deployment than the one they were expecting The French moved most of their troops by train, although there are reports of the French using taxis and marching large numbers of troops to get them into position in time. All of this meant that by the time the Germans got into France, the French were there waiting for them. Logistical shortcomings: van Creveld says that (7) Schlieffen does not appear to have devoted much attention to logistics when he evolved his great Plan. He well understood the difficulties likely to be encountered, but made no systematic effort to solve them. Had he done so, he might well have reached the conclusion that the operation was impracticable. Moltke did much to improve the logistic side of the plan. Under his direction, the problem was seriously studied for the first time and officers trained in the techniques of warfare Moltke did indeed make a number of alternations to the plan. From a simply logistical perspective, some of these changes were for the better, but most were detrimental to the cohesiveness of the plan was a complete stratagy. Creveld concludes that, overall, the logistical shortcomings of the plan did not contribute to the German defeat on the Marne.However had the  battle  gone in Germanys favour there is every reason to believe that the advance would have petered out. The prime factors would have b een the inability of the railheads to keep up with the advance, the lack of fodder, and sheer exhaustion. In this sense, but no other, it is true to say that the Schlieffen Plan was logistically impracticable. In van Crevelds view(7) the layout of the plan was did not have the necessary standard of thoroughness and detailed planning that was thought to be the hallmark of the German General Staff, but by  an ostrich-like refusal on Schlieffens part to face even those problems which, after forty years of peace, could be foreseen.  Although Moltke did improve the logistical elements of the plan to take into account modern communications technology., it was not the execution of carefully laid plans which allowed the German advance to enjoy the successes that it did, but  furious improvisation (7) That the German Army performed as well as it did when the orders they were receiving were so contradictory and unclear is testament as to what a formidable military force they really were. Moltkes changes to the plan: Chief of the General Staff Helmuth von Moltke altered several elements of the Schlieffen Plan, firstly he reinforced the east with 180,000 men from the right-wing armies to defend against Russia this watered down the invasion force in favour of a more secure eastern border. Moltke was also opposed to the idea of invading the neutral Netherlands in order to provide his armies with a route through to France. The result of this was that his forces were held up in Belgium and this resulted in the breakdown of the whole schedule that the plan was meant to follow. Moltke also moved more troops from his right wing to his left as he was worried that Allied troops could threaten Germany. In the original plan Schlieffen wanted to provide the opportunity for invading armies to threaten Germany before they were enveloped, as this would provide a political victory as well as a military one. This shift of man power became a problem, because the German left flank was now pushing the French back rat her than luring them away from Paris. This meant that the French forces were much closer to the action than was intended and they were condensed rather than spread out. Moltke also sent 80,000 troops to the east to defend against the Russian invasion. In the end Moltke had shifted 250,000 men away from the right wing invasion force watering the assault down to such a point that he had no choice but to abandon the Schlieffen Plan. The French were beaten back by the strongly reinforced left German armies of close to  Sarrebourg; the French forces pulled back and took up defensive positions in the hills near the city of Nancy(5). Instead of avoiding them and enveloping the French armies and Paris as the plan dictated. German high command chose to assault their heavily defended positions around Nancy. This offensive was a total failure. Belgian resistance: Even though the forces defending Belgium were only ten percent of the size of the invading German army, they still managed to hold the German forces up for almost a month, the Belgians quickly lost their forts and military strongholds but they continued to fight in an almost guerrilla style, constantly threatening German supply lines in the North. Also the fact the Germany had invaded Belgium turned European public opinion against them. German underestimation of the British-Belgian alliance: Britain and Belgium were in an alliance because of the  London Treaty that was signed in 1839.(3) Germany did not believe that Britain would keep to the treaty and defend Belgium. The British did keep to their word and surprised Germany by entering the war. This meant that Germany would have to contend with the royal navy and the highly effective BEF in the war. What actually happened was the opposite of what the plan intended (1) because Russia fell before France. The Russian army was defeated with very little cost to the Germans and Russia was forced out of the war before the western front was resolved. Meanwhile the Western front had huge amounts of manpower poured into it feeding the war of attrition that was taking place. The stalemate began to break in the summer of 1918 when Italy finally managed to defeat  Austria-Hungary, and forced them to withdraw from the war. This meant that Germanys southern flank was exposed. The defeat and withdrawal of  Bulgaria  also made Germany venerable to an Allied advance up the  Danube. In 1917 the United States entered the war and brought with it a substantial amount of troops, this meant that Germanys final push in 1918 was defeated and the allies were able to push the Germans out of France and into Belgium and then back towards the German border. Once it became clear that western front was lost, Germany requested terms and the First World War came to a close. There is no denying that the plan came close to success but with so many factors weighted against it and the poor decisions made German high command in regards to the plans execution. the Schlieffen Plan was never going to win the war for Germany. Moltkes fear of Russia proved unfounded and his changes in deployment unnecessary. If these changes had not been made then the plan may have enjoyed more successes as it was the Germans did not have the man power to build on their initial gains and therefore had to retreat. The plan itself however has merit and I think that its fair to say if the execution of the plan had not been watered down so much by Moltke and Schlieffens original plan was stuck to then France may well have fallen and the thin line that separated defeat from victory would have been crossed by the Germans.

Quantitative research

Quantitative research Introduction (150) Quantitative research is the investigation of phenomena that give themselves to exact measurement and quantification, which attached a rigorous and controlled design (Polit Beck 2008). Its has main purpose is to measure concept or variables objectively in numerical and statistical process, also relationship between variables (Parahoo 2006). The research methods are obtained from research design and generally include sample, intervention (if applicable), instruments, data collection, and data analysis (eds. Joyce Meredith 2006). In many instances, the quantitative research needs such as questionnaires or interview, computers and large sample sizes. This article is to explore of a quantitative research by Kalij and William (2009) the view of its data objectivity, sample size and selection, process data collection, data presentation and analysis, using the relevant references to support this discussion. The objectives are to prove with evidences if the Khalij and Williams study (2009) fulfills the requirements of quantitative research. Objectivity (150) Objectivity is amount of involvement of the researcher relates during the collection and analysis of the data (Marcella n.d.a). Polit and Beck (2008) argued objectivity meant researcher tend to stay away any impression of subjectivity or impersonal during study process. Parahoo (2006) explained the data which collected and analyzed are expected to be free from bias between researcher and participants. It means the researcher is detached or does not active participate from practice and there is no intervention between researcher and participant. Also the participants use the same actual measurements for data collection. Further the bias of research can be minimized and the objectivity of the study can be maximized. In The Kalish and Williams study (2009) showed that they did not participate and used measurements to collect the data. It showed in their study that during data collection, they involved staff nurses in four hospitals and used psychometric testing tool. Hard data (148) Hard data is characteristic of quantitative study. Polit and Beck (2008) said that quantitative data are the information obtained during process of study course in a quantified (numeric value). (Janet Houser 2008) argued the other numerical data specific patients symptoms put in rank order the scales which contained intervals, comparisons between subjects. Other instance the researchers with rigorously designed tools should be able to grasp the reality (Parahoo 2006). For example scale of depression and pain in numeric value. That means the data can be measured and quantified in some way. In the nursing practice we always face with the hard data. For instance are physical (height, weight, gender), physiological (vital signs, laboratory results, visual acuity), past medical histories, psychological and social or behavior. This data are shown in Kalish and Williams study (2009) during their study while collected data: sample size, genders, experience, education degree, and work location in quantified data. Statistic (142) Statistic is very important aspect in the quantitative research. After data are collected can be analyzed using statistic and presented in numerical form. Polit and Beck (2008) said that statistic is an estimate of a parameter, calculated from sample data. They emphasized statistics are used to test hypotheses and evaluate the believability of the finding. Researchers usually use statistical computer to expedite calculation and ensure accuracy (ed. Joyce and Meredith 2006). They mentioned statistic methods are used in every process include in the final report to search the correlations, comparisons of means, trend and significance of finding to refute hypothesis. Its reinforce that statistic is one of characteristic in quantitative research. Its applied in Kalishs study process while selecting data sampling and analyzing data which showed in the tables and the data was analyzed by statistical computer, descriptive statistic and inferential statistic. Sample selection (269) Janet Holt (2009, p. 235) said that sampling is the process to select a small group of participant for study with the goal of making generalization from large population based on findings. Polit and Beck (2008) argued that sampling is the process of selecting portion of the population to represent from the entire population element. There are differentiation ways in sample selection; sampling designs, sample size and sampling steps. Polit and Beck (2008) mentioned that there are two sampling designs; probability sampling and non probability sampling. Probability sampling contents; simple random, stratified random, cluster and systemic sampling. The non probability sampling has contents; convenience, quota and purposive sampling. Janet Houser (2008) explained sample size in quantitative research to determine sample in adequacy is power. Its an analysis to indicate the large of sample which needed to adequately detect a difference in result variable. Polit and Beck (2008) suggested the steps in this research sampling as follow; the population identify, the specific eligibility criteria, the specific sampling plan and sample recruitment. They emphasized researcher during sample recruitment to gain the participant cooperation use means of courtesy, persistence, incentives, research benefits, sharing results, convenience, and endorsement. This study sample collection was implemented in the kalishstudy. They used random sampling to collect the participant data from four hospitals in different unit. The study used N symbol which designed for the total number, and n symbol is designed for number of subject. They took large sample size with total samples (N=1098). They applied ratio of sample size during sample collection. They gained the participant cooperation which provided incentives (jumbo-sized candy and bar a pizza party). Data collection (285) Parahoo (2006) said data collection is methods to measure the data sampling which utilized the instrument tools: questionnaires, observation schedule and other measuring tools. He emphasized that the methods should be predetermined, structured and standardized. Polit and Beck (2003) developed data collection plan include identifying data needs, selecting types of measures, selecting and developing instruments, pre testing the data collection package, and developing data collection forms and procedures. They stressed Important aspects should be considered while implementing the data collection plans are the selecting research personal and personal and the training data collector. Nancy and Susan (2007) explained data collection is the process of obtaining the subject and collecting the data for the research. They explained five tasks during data collection process: recruiting subjects, maintaining consistency, maintaining controls, protecting study integrity, and solving the problem. Structure, quantifiability, obstrusiveness, and objectivity are important elements when selecting data collection instruments (Marcella n.d.a). We have to understand and maintain the important dimension the data collection methods when applied in the data collection plan, and implementing. The obtained data should be accurate, valid, and meaningful to respond the questions. Kalish and William implemented the data collection process in their study. They applied the approaching methods to maintain the important dimensions in data collection such as a tool of missed nursing care and reason for missed care. The Data collection plan used to identify data needs for instance in the describing sample characteristic of participants (table 2.). They construct the tool in their survey to gain the quantify data. While implementing data collection, they selected research personal is staff nurse experts. The training data collector was done which distributed a copy of tool, informed consent form and a letter explaining the study. Data analysis and presentation (299) Joyce and Meredith (ed. 2006) said data analysis is a systematic method of examining data gathered for any research investigation to support hypothesis. This system implements in the data analysis process: the data analysis preparation, the sample description, reliability of measurement test, exploratory analysis conduction, exploratory analysis, confirmatory analysis and posthoc analysis conduction (Nancy Susan 2007). Parahoo (2006) stated analysis data can be obtained from measurement level, and then analyzed with statistical level. He mentioned two statistic levels those are descriptive statistic and inferential statistic. There are several statistical computer programs (SPSS, SAS, LISREL, EQS, etc) which help the researcher to calculate these test statistics and their sampling distribution (eds. Joyce Meredith 2006). Marcella (n.d.b) explained there are two types of inferential statistics are parametric (t-test, ANOVA, Multiple regressions) and non parametric (Chi-square, Rank Correlation, Mann-Whitney U, Kruskal-Wallis). Quantitative research result may be presented in the tables, charts and graphs (Michael, Patricia Frances, 2007, cited Russell, 2005). In conclusion that data analysis is systemic method of examination data started from data collection which used measurement level then data were analyzed by statistical level and presented in the tables, charts and graphs to support hypothesis. Kalish and Williams study (2009) implemented the data analysis process which utilized measurement level and statistical level which completed using SPSS in their study. First step is checking of data accuracy using ordinal scale. The second is describing sample, they use central tendency and dispersion to test the contrast validity. The third is testing the reliability of measurement, they applied cronbach alpha coefficient. Fourth they conducted exploratory analysis as the extraction technique and varimax as orthogonal rotation method, also analyzed using oblique rotation. Fifth they conducted the confirmatory analysis used AMOS version 16. Last step they used analysis of variance (ANOVA) to conduct posthoc analysis. Result study was presented in the table presentation. Conclusion (118) This essay has tried to explore the Kalish and Williams study (2009) about the development and psychometric testing of a tool to measure missed nursing care. Their study has approached and fulfilled the major requirement of quantitative research characteristics that include objectivity, hard data and statistic. They applied quantitative study process which consists of conceptual, design and planning, empirical, analytic and dissemination phase as suggested by Polit and Beck (2004). They also utilized data analysis process of Nancy and Susan (2008). In general view of Kalish and Williams study (2009) has applied the quantitative research systematically. Improvement progress monitoring was done, but effectiveness overview the tool is still recommended to apply in the base practice for long period. References: 1. Carol L. Macnee Susan Mc.

The High Price of In Vitro Fertilization :: Exploratory Essays Research Papers

The High Price of In Vitro Fertilization MAKE A DREAM COME TRUE. GIVE THE GIFT OF LIFE! BE AN EGG DONOR. $6,500 STIPEND AND EXPENSES PAID. When twenty-year-old Maria Slone first saw the ad in her college newspaper, she remembers thinking, â€Å"Damn, that’s a lot of money!† She called up immediately, envisioning an egg-plucking process that would be as quick and effortless as sperm donation. Disappointingly, the receptionist at Woman to Woman Fertility Clinic didn’t give her the time of day, mostly because that was last spring and Maria wasn’t twenty-one yet, but also because she seemed a tad too money-hungry for the well-to-do clinic. Looking back, Maria smiles a little sheepishly. Now, one year later, and halfway through the process of donating her eggs to an infertile couple, she knows what she’s in for, both emotionally and physically. Already, she’s wrestled with the idea of selling her genetic material to strangers—she’s taking the unusual step of meeting with the couple who chose her genes from a stack of manila folders. And now she’s overcoming a lifelong abhorrence of needles by playing doctor—she’s injecting a syringe full of milk into a grapefruit, mentally bracing herself for the ovary-stimulating hormones she’ll inject into her own thighs and buttocks for ten days next month. But Maria’s taking both the emotional and physical sacrifices in stride because at the end of August—after ten or more of her eggs are retrieved from her ovaries—the Woman to Woman Fertility Clinic will cut her a $4,000 check. The payment promises a soothing aloe to Maria’s staggering list of financial woes: crushing legal fees, spiraling credit card debt, student loan payments, and a hankering for a liposuction procedure that could cost up to $4,000. Already, she spends long, hot Saturdays babysitting for a hyper five-year-old boy, and on weekdays leads troops of rowdy teenagers on tours through the State Capitol. Both jobs barely subsidize rent, groceries, and the weekend recreational pleasures that 21-year-old college students indulge in. That’s why, after being rebuffed once, Maria called again four months ago. The information packet came in the mail only three days after Maria dialed the 1-800 number. From the vital statistics she provided over the phone—blond hair, blue eyes—she was an instant hit. The receptionist at the fertility clinic made her voice buttery sweet, over-eager to please.

Determination Of Water Crystalization Essay

I. Aim: To determine the formula of the hydrate of copper (II) sulfate. II. Hypothesis: Hydrates are ionic compounds that have a definite amount of water as part of their structure. The water is chemically combined with the salt in a definite ratio. Ratios vary in different hydrates but are specific for any given hydrate. In this experiment, the hydrate of copper sulfate has the formula CuSO4.xH20. When it is heated, the water is released as vapor and we can describe the reaction as below: Hydrate Anhydrous salt + Salt CuSO4.xH20 CuSO4 + xH20 The amount of water in the hydrate is determined by taking the difference between the mass of the hydrate before and after heated. Then, the percentage composition of water can be calculated basing on its mass. According to usual theory, hydrated copper sulfate has the following formula CuSO4.5H2O. Therefore, the result collected from the experiment should be x = 5. III. Equipment/Chemical: 1. Equipment: * 1 x Evaporating dish * 1 x Pipe-clay triangle * Some crucible tongs * 1 x Pressed fiber pad * 1 x Digital balance (uncertainty: à ¯Ã‚ ¿Ã‚ ½0.001g) * 1 x Spatula * 1 x Glass stirring rod * 1 x Bunsen burner * 1 x Tripod stand 2. Chemical: Hydrated copper (II) sulfate IV. Variables: * Independent: the mass of hydrated salt. * Dependent: the percentage composition of water in the hydrate. * Control: room temperature, capacity of fire gas, standard equipment. V. Method: 1. Clean and dry evaporating dish. 2. Set up a Bunsen burner under a tripod stand with a pipe-clay triangle on top. 3. Place the empty evaporating dish on the clay triangle and heat the dish with the hottest flame for 3 minutes. This is done to be sure that the dish is absolutely dry. 4. Use tongs to remove the dish from the clay triangle and then place it on a pressed fiber pad so that it can cool for several minutes. 5. Use a digital balance to determine the mass of the cooled evaporating dish. Record this mass to the same number of decimal places as the uncertainty of the balance (à ¯Ã‚ ¿Ã‚ ½0.001g), in other words, the measured mass will have 3 decimal places. Remember not to weigh the dish when it is hot because heat waves tend to be circular and upward, which tends to make objects appear to weigh less. 6. With the dish on the balance, put into it a specific amount of hydrated copper sulfate; make sure that the amount of hydrated copper sulfate is less than half full of the dish. Be sure the spatula is very clean to avoid contamination. Record the mass of the dish with the hydrate to the same number of decimal places as the uncertainty of the balance. 7. Place the dish on the clay triangle. Gently heat the dish by moving the burner bark and forth around the base. Increase the heat gradually. Avoid any popping and spattering. 8. Heat strongly for 5 minutes or until all of the blue color has disappeared. During the heating, a glass stirring rod should be used to spread the solid and break up larger portions of the hydrate. Be sure not to pick up any of the solid on the stirring rod. If the edges of the solid appear to be turning brown, remove the heat momentarily and resume heating with a cooler flame. 9. Allow the dish to cool for 2 minutes. Immediately find the mass of the dish with the anhydrous salt, and record the mass to the same number of decimal places as the uncertainty of the balance. The dish must be weighed before the compound reabsorbs water from the atmosphere. 10. Calculate the initial amount of hydrated copper sulfate before heated. Record the answer to the same number of decimal places as its calculated uncertainty. 11. Determine the amount of vaporized water. Record the answer to the same number of decimal places as its calculated uncertainty. 12. Then, the value of x can be found basing on the formula ratio. 13. When finish, the anhydrous salt can be thrown into the waste container and the evaporating dish washed.

Development Of Greek Philosophy

Greek Philosophy emerged because of the following thinkers: Thales, Pythagoras, Heraclitus, Parmenides, Socrates, Plato, and last but not least, Aristotle (Bennagen, 2000). This paper entitled, â€Å"Development of Greek Philosophy† intends to describe the thinkers involved, key schools, as well as their ideas. First stop is Thales, who emerged in 610 to 546 BC (Bennagen, 2000). He is said to be the first philosopher because of the fact that he motivated people to think that the world in all made up of water (Bennagen, 2000).Second is Pythagoras, who came about in 582 to 507 BC (Bennagen, 2000). For Pythagoras, number is the most essential thing in life (Bennagen, 2000). It was him who established the relationship between angles and sides of the right triangle which he later technically referred to as the Pythagorean Theorem (Bennagen, 2000). Third is Heraclitus, who presented itself from 535 to 475 BC (Bennagen, 2000). For him, everything continuously changes and that stabili ty does not exist (Bennagen, 2000). True enough because even those stable things, as they appear to be, are not (Bennagen, 2000).Examples include neutrons, electrons, and quarks (Bennagen, 2000). Fourth is Parmenides, who made himself known from 610 to 547 BC (Bennagen, 2000). He was the founder of the school known as â€Å"Eleatics† (Bennagen, 2000). For him, change is unreal, it is merely an illusion (Bennagen, 2000). In addition to that, for him, reality or â€Å"being† is everlasting, fixed, and undivided (Bennagen, 2000). He warns us that we should not always trust our senses when it comes to what reality is (Bennagen, 2000). Fifth is Socrates, who emerged in 469 to 399 BC (Bennagen, 2000).Socrates focused on the health of the soul and thus, he motivated people to look further into ethics or morality instead of nature as the first four philosophers were deeply interested in (Bennagen, 2000). Sixth is Plato (427 to 347 BC) who believes that reality is divided into two the perfect and imperfect (Bennagen, 2000). He also presented his ideal state and ideal leader to show his definition of reality (Bennagen, 2000). Last but not least is Aristotle who went to study things further using his senses, consequently discovering science itself (Bennagen, 2000). Reference Bennagen, P. (2000).
