The Worlds Most Popular Languages

There are 6,909 languages actively  being spoken in the world today, although only about six percent of them have more than a million speakers each. As globalization becomes more common so does the learning of languages. People in many different countries see the value of learning a foreign language to improve their international business relations. Because of this, the number of people who speak certain languages will continue to rise. There are 10 languages that currently dominate the globe. Heres a list of the 10 most popular languages spoken worldwide, along with the number of countries where the language is established, and the approximate number of primary or first language speakers for that language: Chinese/Mandarin—37 countries, 13 dialects, 1,284 million speakersSpanish—31 countries, 437 millionEnglish—106 countries, 372 millionArabic—57 countries, 19 dialects, 295 millionHindi—5 countries, 260 millionBengali—4 countries, 242 millionPortuguese—13 countries, 219 millionRussian—19 countries, 154 millionJapanese—2 countries, 128 millionLahnda—6 countries, 119 million The Languages of China With more than 1.3 billion people living in China today, it is no surprise that Chinese is the most commonly spoken language. Due to the size of Chinas area and population, the country is able to sustain many unique and interesting languages. When speaking of languages, the term Chinese encompasses at least 15 dialects spoken in the country and elsewhere. Because Mandarin is the most commonly spoken dialect, many people use the word Chinese to refer to it. While roughly 70 percent of the country speaks Mandarin, many other dialects are spoken as well. The languages are mutually intelligible to a varying degree, depending on how close the languages are to one another. The four most popular Chinese dialects are Mandarin (898 million speakers), Wu (also known as Shanghainese dialect, 80 million speakers), Yue (Cantonese, 73 million), and Min Nan (Taiwanese, 48 million). Why Are There So Many Spanish Speakers? While Spanish is not a commonly heard language in most parts of Africa, Asia, and the majority of Europe, that hasnt stopped it from becoming the second most commonly spoken language. The spread of the Spanish  language is rooted in colonization. Between the 15th and 18th centuries, Spain colonized much of South, Central, and large parts of North America as well. Before being incorporated into the United States, places like Texas, California, New Mexico, and Arizona were all part of Mexico, a former Spanish colony. While Spanish is not a common language to hear in most of Asia, it is very common in the Philippines because it too was once a colony of Spain. Like Chinese, there are many dialects of Spanish. The vocabulary between these dialects varies greatly depending on what country one is in. Accents and pronunciation also change between regions. While these dialectical differences can sometimes cause confusion, they do not block cross-communication between speakers. English, a Global Language English too, was a colonial language: British colonial efforts began in the 15th century and lasted until the early 20th century, including places as far flung as North America, India and Pakistan, Africa, and Australia. As with Spains colonial efforts, each country colonized by Great Britain retains some English speakers. After World War II, the United States led the world in both technological and medical innovation. Because of this, it was considered beneficial for students pursuing work in these fields to learn English. As globalization occurred, English became a shared common language. This caused many parents to push their children to study English as a second language in the hopes of better preparing them for the business world. English is also a useful language for travelers to learn because it is spoken in so many parts of the globe. A Global Language Network Since the popularity of social media, the development of a Global Language Network can be mapped using book translations, Twitter, and Wikipedia. These social networks are only available to elites, people with access to both traditional and new media. Statistics of use from these social networks indicate that while English is definitely the central hub in the Global Language Network, other intermediate hubs used by elites to communicate business and science information include German, French, and Spanish. Currently, languages such as Chinese, Arabic, and Hindi are vastly more popular than German or French, and it is likely that those languages will grow in use of traditional and new media.

The Rhino And Elephant Ivory Market - 1792 Words

Abstract As the economic growth in the world continues, Africa continues to lose its self-proclaimed title as the cradle of biodiverse ecosystems which house the mighty African elephant and rhinoceros (otherwise known as the continental herd). Wildlands have been fragmented and forests cleared continuously and at very rapid rates. Rising rates of affluence around the world, especially in Asia has led to the intensity of the black market of the rhino and elephant ivory market which has seen the deterioration of this vast and much needed component of the ecosystem. Many governments within the continent, in conjunction with countless non-profit private institutions have proposed regulated hunting and laws against wildlife poaching. This legislation has seen taxes and fees being generated into these states which have been set as capital for conservation programs which have been both positive and negative. Where positivity has come, the restoration of species has been remarkably recorded, for example the white rhino in Southern Africa In places where these conservation programs are poorly managed, the benefits are much harder to prove, especially in ecosystems where the populations have already been depleted. This paper will ensue a descriptive knowledge of numbers and distribution of the elephant and rhinoceros examining the changes in population. It will also site the methods, including framework for improved forest governance, in which innovative, successful and lastingShow MoreRelatedPoaching Problem1738 Words   |  7 Pagescome up with.

Current Policies of WHS-Free-Samples for Students-Myassignment

Question: Discuss about the Current Policies of WHS. Answer: WHSMS in brief A work health and safety management (WHSMS) can said to be an organized system in relation to the work health and safety management system in workplaces. Therefore, it is a framework that permits the management to put a complete system of protection in place. The size of an organization will determine how complex the system will be, along with the manner in which it is organized and the nature of the business. A WHSMS requires various things, which includes strategies of communication and consultation, review and control of documents, control of purchasing, a review of work based health and safety systems and also an account of internal and external auditing (Straker et al., 2016). In order to implement a WHSMS effectively, there must be full commitment on the managements part along with the training of the employees in the new policies and procedures. Duty holders in Australian WHS In Australian WHS, a duty holder can be said to be a person, who is like a sports manager, who ensures that the all matters in sports are managed according to the constitution of the club and who becomes answerable to the governing body of the club. Therefore, a duty holder is a person who ensures that health and safety is maintained in a workplace (Fewster, 2015). According to the Work Health and Safety Act, 2001 and the Work Health and Safety Regulations 2011, duty holders are those who have a duty to eliminate all health and safety related risks or to minimize such risks in order to ensure health and safety in workplaces (Claxton, 2017). Under the Australian WHSMS, there are three types of duty holders. They are: PCBUS (Person undertaking a business or undertaking) - A PCBU may be defined as an organization or an individual person, conducting an undertaking or business (Martinov-Bennie et al., 2014). For example, public companies, private companies, government departments and authorities, schools, partners in partnership, sole traders and self-employed, individual trustee of trusts, etc Officers- Officers include senior executives who make or participate in decision making, which affects the business or undertaking either partly or solely. AN officer can be a person defined under section- 9 of the Corporations Act (excluding a partner in partnership), an officer of the Crown and a public authority officer. Workers and other persons at the workplace- Includes all other people in the workplace and also those who are present at the workplace. It is to be mentioned that the WHS Act clearly states that an individual is not a PCBU in cases where they are in an undertaking or a business only as an officer or worker. Individuals include directors belonging to managerial positions and having specific and separate duties as officers. WHS Resources There are certain resources, which are required to be allocated for ensuring that the WHS obligations are met. These resources include financial, human and management support (Grasso, 2016). In cases of additional resources for managing WHS, the senior manager or the executive manager must take necessary steps accordingly. Some of the resources that are required are: WHS toolbox talks- This includes a number of power point presentation, which is used in the staff meetings, etc and acts as the basis of the toolbox talks in order to provide opportunity for refresher training or reinforcement of key areas. Human resources for managing WHS- It must be ensured by the workers that the workers have adequate training and resources for keeping themselves safe and for understanding potential risks and ability to act in accordance with such risks, when identified. Safe posters- These posters usually provide a safety guide in workplace for the workers and include guidelines for safe work. Use of this is also helps in implanting work health and safety in workplaces. Other resources of providing healthy workplace- The various other measures relating to health of the workers are also a source of WHS, which is highly required. Communication/Consultation plan Consultation or communication on health and safety is a process that goes in two ways and it is regarded as the opportunity to add value while making decisions. This process involves talking about issues, listening and raising concerns, role understanding, seeking of information and sharing of views, discussion on such issues, attending meetings and considering everything before decision making. Such communication/ consultation plans are made by the WHS experts (Gunningham Sinclair, 2014). Consultation and communication along with collaboration is a fundamental part of the WHSMS and also a part of each strategic objective with the health and safety strategy. It is not possible to achieve communication, consultation and collaboration effectively with a single strategic objective or project, which is carried out with in that particular objective. It must be done in a way daily business is conducted. For proper implementation of a WHSMS, it is important to communicate information effec tively so that all the potential stakeholders can understand it, which is imperative for the purpose. WHS experts are the duty holders under the WHSMS. They play an important role in communication and consultation. The health and safety measures in a workplace is comm8nicated by these duty holders and similarly all problems must be communicated to them so that they can take necessary measures and implement the WHS legislations and regulations in order to use maintain the work health and safety standards in workplaces (Zhang et al., 2015). The OHS Act, 2004 makes it a legal requirement that effective consultation must be done in regular intervals with the employees in a workplace as engaging the employees will help in improving the health and safety in workplaces. The Workplace Manager, Management OHS Nominee and the HSR are the WHS experts and are responsible for maintaining WHS standards. The Workplace Manager or the OHS Nominee must make consultative arrangements with the Health a nd Safety Representative (HSR) and employees while making or taking any decision regarding The OHS/WHS in workplace. In case of information that is confidential, the management OHS Nominee or and the Workplace manager must take legal help before making any decisions. The HSR, management OHS nominee, workplace manager, all should, in accordance with the WHS/OHS Act, disclose all such information to the employees and consult with them, which is required. They are also required to implement OHS issue resolution process. For such resolution process, the OHS resolution Flowchart is used, which is to be communicated to the employees and prominently displayed in the workplaces (De Cieri et al., 2015). Thus, it is important and a mandate under the WHS standards, to create a communication/consultation plan and use it accordingly, to implement the WHS standards in the workplaces, with the help of the WHS experts. Requirements of WHS in case of participation agreements In order to provide issue resolution to the Naja Group of Colleges, the requirements can be emphasized. It is noteworthy to mention here that in order to resolve issue arising out of various sections, it is necessary that the parties to the issue must be present while resolving the issue (Forsyth, 2014). The issue must be resolved in consultation with the workers who has been affected and the Person Conducting a Business or Undertaking (PCBU). In order to resolve issues, the management of the Naja Group of Colleges has taken various steps in order to ensure health and safety in workplace. The PCBUs has been encouraged by the Work Health and Safety Act 2012(SA) (WHS Act) to involve procedures of issue resolution in order to solve disputes with the workers (Ghahramani, 2016). However, in the absence of agreed procedures, the procedure of issue resolution which is depicted under the Work Health and Safety Regulations 2012 (SA) (WHS Regulations) needs to be followed (?nan, Gl Y?lmaz, 2017). In this regard, it is noteworthy to mention here that, the actual procedure for resolving issues is depicted in Regulation 22. In order to resolve issues, the Naja Group of Colleges acted according to the regulations of WHS and followed the default procedure for the purpose of issue resolution in Regulation 22. In this context, the Naja Group of Colleges in an attempt to resolve the issue arising out of health and safety has undertaken the following matters- The degree of risk involved to the workers and other persons working for the organization. The location and number of such workers including other persons who has been affected by the issue. The permanent and temporary measures that needs to be implemented for the purpose of resolving the issue. The person who will take the responsibility in implementing various measures of resolution. It is important that any individual conducting a business should interact with the workers in order to keep track of the issues faced by them (Johnstone, 2014). Therefore, in the present case the Naja Group of Colleges has acted according to the measures set up by the WHS Act in order to identify various risks and hazards associated with the work carried out by the workers. In this regard, the Naja Group of Colleges has been successful in making decisions for the purpose of eliminating the risks involved in workplace. The management of the Naja Group of Colleges should consult with the present workers and propose various changes so that it benefits the working environment and improves the health and safety conditions of the organization. It is important to provide feedbacks on various outcomes. However, it is important that such feedback must be positive and should be related to workers health and safety. Identifying the inadequacies The legislation of WHS in Australia emphasized on the part that PCBUs must consult with the workers in order to identify the hazardous risks or situations arising out of workplace (Lingard, 2015). Therefore, in case of the Naja Group of Colleges, it is important that the management of the organization should undertake various situations in which risks are likely to be found. The management should identify the working environment of the organization including the past accidents and make sure that such accidents do not occur again. The management should focus on the risks involved while using age old equipments and materials which can be hazardous at times. In this regard, the management should take into consideration the Material Safety Data Sheets in order to determine various safety precautions. In order to identify the inadequacies it is important to take into account the various risk factors that are involved in a workplace (McDermott, Henne Hayes, 2017). In an organization, various risks factors are involved which needs to be identified. Therefore, in the present case study, it is necessary that the management of the Naja Group of Colleges should review the information related to health and safety and such information should be obtained from any authoritative source so that it can be relied upon. However, it is necessary that such information should be relevant to the identified inadequacy. After the identification process, it is important for the management to evaluate the nature of the hazard regarding its seriousness (Mohammadfam et al., 2016). In this regard, the management of Naja Group of Colleges should take into account the various kinds of injuries, damages and illness that could arise as a result of the hazardous incident. It is necessary the that management sh ould also evaluate the number of workers exposed to such incident as well as the possible outcome that could result due to exposure to this kind of hazard. The management is at the duty to evaluate the factors that could actually cause harm and affect the betterment of the workers to a large extent (O'Neill Wolfe, 2014). In this regard, it is noteworthy to mention here that the management should consider the related chain of events which are consistent to the nature of the risk. However, the level of risk may increase the likelihood of harm in the future. The concept of likelihood of harm is involved when there is a situation that is concerned with consequential harm (Schofield, Reeve McCallum, 2014). In this regard, the management is at the authority to determine that in what way and in what conditions the maximum number of workers will be exposed to a hazardous situation keeping in track the duration. Requirements, use and maintenance of records For the purpose of record keeping, the requirements, use and the maintenance of records should be considered. In this regard, it is noteworthy to mention here that the management of Naja Group of Colleges should act in accordance with the details provided by the record keeping requirements as depicted in the Model Work Health and Safety Regulation. The following areas have been covered by the Model Work Health and Safety Regulation- The contaminated levels of Air-borne. Work related to high risk. Confined spaces. Electrical installations and equipment. Presence of hazardous chemicals. Lead and Asbestos. Facilities involving major hazards. According to the provisions of Section 50(2) of the WHS Act, it is important that the management of an organization must record the results associated with air monitoring and such records should be kept for thirty years from the date on which such record has been made (Sutherland, 2015). The management should also keep records of risk management associated with confined spaces according to Section 66(3). However, such record should be in writing. For the purpose of electrical equipments and installations, the record shall be carried out b a competent person with the help of electrical equipment which has been supplied with electricity involving an electrical socket. However, it is important that such testing procedure must be carried out in an environment where the risk of damage is low and the persons carrying on the record is not affected in any way. The management of the Naja Group of Colleges should hire an individual who shall be concerned with the control of plant in order to keep records of inspections, maintenance and other safety measures. The person concerned with the supply of prohibited and hazardous chemical must keep the records which includes the name of the substance as well as the quantity supplied. In this regard, it is noteworthy to mention here that the management of Naja Group of Colleges must hire a person who will be concerned with the task of maintain a asbestos register. The asbestos registered must be prepared by the person of the concerned management and should be kept at a safe place. It is important that the management of every organization should maintain health monitoring reports. Similarly, in case of Naja Group of Colleges, the management should undertake health monitoring reports which are related to a worker carrying out the activities of the business. However, such records should be kept confidential. Importance of monitoring, measuring and assessing the WHSMS For the purpose of monitoring, measuring and evaluating various risks and hazards associated with the workplace, it is important that the management should work according to the principles of OHSMS (Teague et al., 2014). However, two important purposes are associated with the process of monitoring and measuring (Roberts, 2014). Firstly, it is important for the part of the management to assess that whether the OHSMS is working accordingly or not. Secondly, in order to make sure that the safety and health problems have been identified properly, the identification is sent back to the OHSMS planning process with an aim of elimination. The process of identifying and tracking leading indicators are also associated with the process of monitoring, measuring and evaluating. In addition to this other important factors that are associated with the process of monitoring and measuring are inspecting workplace, testing of workplace, exposing assessments, obtaining suggestions regarding safety from employees and evaluating health assessments related to occupation.

The Tet Offensive, Which Occurred On January 31, 1968, Proved To Be A

The Tet Offensive, which occurred on January 31, 1968, proved to be a political and a psychological victory for the Vietnamese communists. And, although it only lasted for about one month, it was one of America's most notable battles that taught the Americans and the Vietnamese valuable lessons about life and war. The background of the Tet-Offensive is very interesting, one hidden within the conflict of the Vietnam War. While the offensive was being planned, there were anti-war demonstrations taking place in the U.S. against the Vietnam War. Lyndon B. Johnson, in a close election, won the primary over McCarthy who happened to be against the war, and then went on to running the country with few problems. In Vietnam, General Vo Nguyen Giap of North Vietnam told his political members that the opportunity for a general offensive or uprising was within reach. The offensive began in August of 1967, when following Hanoi's decision to proceed with Giap's"uprising," Giap began a massive buildup of troops, equipment, and supplies in South Vietnam. First, thousands of guns and munitions were bought southward along the Ho Chi Minh Trail. The Ho Chi Minh Trail was the vital Vietcong (also known as the South Vietnamese) supply line that twisted through the jungles of North Vietnam in a southward direction ("Vietnam"). This trail also served as a transportation route for food and medical supplies being brought to the south part of Vietnam. Tens of thousands of troops poured down from the North, infiltrated the countryside, and wearing civilian clothes, easily blended with the local people. By mid-January, 1968, about 84,000 of the North Vietnamese Army (NVA), and the Vietcong troops were in South Vietnam ("Massacre"). And, two weeks before the actual attack would even take place, Giap's troops were positioned and ready for an attack (Coteau 2). The U.S. began to have suspicions about some sort of uprising taking place. So the offensive did, in fact, not take Americans by surprise. American intelligence sources had started uncovering evidence that indicated a shift in enemy strategy in the late summer/early fall of 1967. The 101st Airborne Division, on November 19, seized an attack order telling that the offensive was near, and some slightly detailed plans of what was going to happen and how it was going to happen ("Vietnam"). The U.S. intelligence officers took this evidence as propaganda and disregarded it completely. The found attack order was then published on January 5th, but still attracted very little attention. As 1968 approached, the U.S. appeared to be winning the war, but in Washington, on December 18th, General Earle G. Wheeler, joint Chief of Staff, cautioned that "it is entirely possible that there may be a Communist thrust similar to the desperate effort of the Germans in the Battle of the Bulge in World War II" (Young 27-28). The U.S.'s suspicions about a possible uprising became stronger as the Tet-Offensive grew closer. In Saigon, on December 20th, General William C. Westmoreland of the U.S. Army cabled Washington that he expected the North Vietnamese Army and the Vietcong to "undertake an intensified countrywide effort, perhaps a maximum effort over a relatively short period" (73-74). On the same day, December 20th, the President warned the world that "we face dark days ahead" (Mueller 3). These events began to foreshadow the Vietnamese's coming psychological victory. In January of 1968, American forces captured a pair of NVA operation orders calling for an attack on Pleiku before the Tet, and targeting Ban Me Thuot for assault. Two days prior to the Tet, agents of the South Vietnamese Military Service arrested eleven Vietcong leaders that were caught holding a secret meeting ("More"). The eleven had two tapes that had messages about the liberation of Saigon, Hue, and other cities. Too many warnings of the offensive were ignored. One U.S. intelligence official stated "If we'd gotten the whole battle plan, it wouldn't have been believed. It wouldn't have been credible to us" (Omicinski 18-19). Intelligence analysts refused to believe that the Vietcong and the NVA were capable of executing such a large scale, coordinated attack, but they were not sure if the Vietcong and NVA were, or if they were not. The U.S.'s suspicions on the upcoming offensive were starting to be confirmed. By mid-January, Westmoreland was almost sure that the offensive would be starting just before or just after the Tet. The U.S. and its officials had strongly doubted that the Vietcong and the NVA would strike during the holiday. The Tet is a very important and religious holiday in

Deconstruction of Leadership Assumptions

Deconstruction of Leadership Assumptions In our rapidly changing world, leaders play a vital role in impacting organizations and the welfare of their followers. Some positive attributes that enhances a successful leader includes initiating new ideas, seeking others opinion and being firm but rigid (Fisher, 1974). Most importantly, leaders who develop the culture of self-awareness towards their subordinates and the organization create an atmosphere of harmony and collaboration.As we take the initiative to deconstruct our leadership assumptions that influenced us personally, our workplaces and academically, we will focus on emotional volatility, withholding information and favoritism. Also, we outlined a revised explanation of these assumptions and a discussion on how these improved us professionally, academically personally.According to Paparone (2004, p.3) a deconstruction is an analysis of statement that has the tendency of demeaning, contradicting or omitting what was originally stated. On the other hand, assumptions are thoughts that emanates from the unconscious or natural (Duplass Ziedler, 2002) used to support in making decisions periodically (Ruggiero, 2004, p.141).Goldman Sachs ProtestsKirby and Goodpaster (2001) said, deconstruction makes us to be conversant of the lack of facts that promotes our behavior. Thus, enabling us to either continue accepting the assumption, provided it is worthy enough to support the truth or reject it to avoid conflicting evidence that affects our judgment (Paparone, 2004).Assumption about emotional volatilitySome of us have undergone a long period of emotional volatility due to loss of family member, war trauma and fragile relationships. Anger leads us into depression, brings about extreme patterns of behavior and thus makes it difficult for us to lead others. The negative aspect of emotional volatility is it muzzles our ability to change. Consequently, once we are noted with the reputation of emotionally volatile we are stigmatized for life.Revised AssumptionsA ccording to Goldman (1995), our intellect cannot work without...

Platos account

Discuss the significance and relevance of Platos account of mimesis and the authenticity of the copy in respect of one of the following films: The Matrix. In your answer pay close attention to both the films form and its content. The Wachowski brothers The Matrix presents a world of illusion, where nothing is as it seems. A world created by computers, run by artificial intelligence. It draws strongly on Platonic theory by showing that only when this fake world is looked at from the outside, from an objective viewpoint, can it be understood, and only when this world of imitation is understood can it be overcome. The work of art in the contemporary world sees allegory, ie. the ability of the story to tell another point for point, as a crucial characteristic. This criteria allows for depth in the work beyond aesthetic, giving art various possible readings and interpretations and allowing the artist/director to retell a story and simultaneously put their own perspective on the tale. The sci-fi epic The Matrix is a prime example of this very post-modern trait. Several allegories are contained within The Matrixs structure and content. The obvious and relevant allegories that of Platos cave. Interestingly, the ancient Greek philosophers cave story was itself an allegory devised by Plato for the degree to which our nature is educated for the state of human existence, or for the plight of man as Plato saw it. The Matrix, in this light, is a copy of a copy. Looking at the movie in regards to its similarities with Platos text. Plato begins by conjuring an image for his audience: people living in an underground place, like a cave. They are restricted in their visions of the world by chains, and they have been there ever since childhood. Similarly, in the Matrix, the human species is being controlled by artificial intelligence. The people are in captivity, and the...

Charles Goodyear Research Paper Example | Topics and Well Written Essays - 1750 words

Charles Goodyear - Research Paper Example In truth, his story is an inspirational application of scientific principles to economic reality, with Goodyear’s frequent and often futile attempts to secure capital to apply his ideas to abundance in everyday life. However, only after his death would rubber become an everyday product and a massive industry of production. In 1898, Goodyear Tire and Rubber Company took Goodyear’s name in commemoration of his achievement. Thus, even though Goodyear never applied his invention to the mass market as other great inventors did in 19th century America, it is still fair to say that Goodyear lived the American dream of experimenting with science to better mankind. Goodyear was born in New Haven, Connecticut on December 29, 1800 to a well-respected, upper-class family. In 1814, the teenage Goodyear left for Philadelphia to learn about industry; returning in 1821, Goodyear entered into a partnership in his father’s business producing various metal-based products. Three years later, Goodyear married Clarissa Beecher and together they moved to Philadelphia where Goodyear, having left his father’s business, opened a general hardware store. He sold agricultural products imported from England. Within a few years, his business was thriving, and by 1829, he had amassed quite a bit of wealth. In 1829, however, his health declined due to a case of dyspepsia, a disease that attacks the digestive system and causes chronic pain in the upper abdomen. Around this time, his business failed as well; eventually, he was forced to close a number of stores. After his health returned, Goodyear undertook a project that would form the basis of his lifeà ¢â‚¬â„¢s work: the vulcanization process of rubber (Peirce). In 1831, Goodyear began researching gum elastic. He experimented with the best method to make rubber; he produced tubes to show to the Roxbury Rubber

HR management in Britain and in EU Essay Example | Topics and Well Written Essays - 2500 words

HR management in Britain and in EU - Essay Example The diplomatic management of human resources comes into play during recruitment. It is also responsible for what is contained in employee contracts, and this includes the aspects of social policy, such as social security benefits, leave, responsibility for work injuries, etc. Managers are responsible too for knowing the talents of the members of their workforce, as this knowledge will lead to better deployment. This is to the advantage of production as well as to the advantage of the employees, who achieve a sense of worth and fulfilment in utilising their best skills. Human resource development is also an important part of human resource management, and while the managers in UK firms play a large role in this, in the newer EU countries (Czech Republic, Poland, and Slovakia) the government takes a much more active role. The European Union has set its own standards for the management of human capital, and these standards must be met by any European state that wishes to enter the union. It realises that "effective management policies lead to employee competence and commitment, congruence between the objectives of employees and management, and is more cost effective" (Price, 2004). Several concerns, however, have been aired. Problems have been foreseen in the area of maintaining quality human resource management across the widening expanse of the European Union. In addition to this, problems also exist where there are discrepancies between and among the HRM policies of different EU member states. Since the European Union allows to some extent for the employment of members across member states, then it is essential for there to exist some level of agreement among the states regarding HRM policies. As it stands, while some states such as the United Kingdom have very advanced policies and robust human re source departments, other states like Slovakia, Poland, and the Czech Republic demonstrate a less developed level of management of its human capital. In order to remove the disparity among EU member states and its candidates, it is necessary first to have a thorough knowledge of the state of affairs in each country and then to compare and contrast to better understand what needs to be done. These nations will be assessed in terms of their managerial structure, managerial policies regarding recruitment, and human resource training and development. The UK model of Human Resource Management The actual term "Human Resource Director/Manager" exists in a large proportion of corporations in the United Kingdom. The existence of such a position demonstrates a high level of commitment to the management of human capital. The HR director overarches other managers who specialise in different areas. In the United Kingdom's private sector, 42% of all firms employing 500-999 persons (smaller firms) have a position with that title. In the larger firms, employing more than 1000 persons, the percentage rises to 65 (Federation of European Employers, 2005). Though not all companies have a position with such a title, there is evidence to suggest that the role does exist. In addition to this, the specialist managers' titles include training director managers,

Augustus de Morgan and George Boole s Contribution to Digital Electronics Essay Example for Free

Augustus de Morgan and George Boole s Contribution to Digital Electronics Essay Augustus De Morgan English mathematician and logician, was born in June 1806, at Madura, in the Madras presidency. His father, Colonel John De Morgan, was employed in the East India Companys service, and his grand father and great-grandfather had served under Warren Hastings. On the mothers side he was descended from JamesDodson,F. R. S. , author of the Anti-logarithmic Canon and other mathematical works of merit, and a friend of Abraham Demoivre. Seven months after the birth of Augustus, Colonel De Morgan brought his wife, daughter and infant son to England, where he left them during a subsequent period of service in India, dying in 1816 on his way home. Augustus De Morgan received his early education in several private schools, and before the age of fourteen years had learned Latin, Greek and some Hebrew, in addition to acquiring much general knowledge. At the age of sixteen years and a half he entered Trinity College, Cambridge, and studied mathematics, partly under the tuition of Sir G.  B. Airy. In 1825 he gained a Trinity scholarship. De Morgans love of wide reading somewhat interfered with his success in the mathematical tripos, in which he took the fourth place in 1827. He was prevented from taking his M. A. degree, or from obtaining a fellowship, by his conscientious objection to signing the theological tests then required from masters of arts and fellows at Cambridge. As a teacher of mathematics De Morgan was unrivalled. He gave instruction in the form of continuous lectures delivered extempore from brief notes. The most prolonged mathematical reasoning, and the most intricate formulae, were given with almost infallible accuracy from the resources of his extraordinary memory. De Morgans writings, however excellent, give little idea of the perspicuity and elegance of his viva voce expositions, which never failed to fix the attention of all who were worthy of hearing him. Many of his pupils have distinguished themselves, and, through Isaac Todhunter and E. J. Routh, he had an important influence on the later Cambridge school. I. n spite, however, of the excellence and extent of his mathematical writings, it is probably as a logical reformer that De Morgan will be best remembered. In this respect he stands alongside of his great contemporaries Sir W. R. Hamilton and George Boole, as one of several independent discoverers of the all-important principle of the quantification of the predicate. Unlike most mathematicians, De Morgan always laid much stress upon the importance of logical training. In his admirable papers upon the modes of teaching arithmetic and geometry, originally published in the Quarterly Journal of Education (reprinted in The Schoolmaster, vol ii. ), he remonstrated against the neglect of logical doctrine. In 1839 he produced a small work called First Notions of Logic, giving what he had found by experience to be much wanted by students commencing with [[Euclid]]. In October 1846 he completed the first of his investigations, in the form of a paper printed in the Transactions of the Cambridge Philosophical Society (vol. iii. No. 29). In this paper the principle of the quantified predicate was referred to, and there immediately ensued a memorable controversy with Sir W. R. Hamilton regarding the independence of De Morgans discovery, some communications having passed between them in the autumn of 1846. The details of this dispute will be found in the original pamphlets, in the [[Athenaeum]] and in the appendix to De Morgans Formal Logic. Suffice it to say that the independence of De Morgans discovery was subsequently recognized by Hamilton. The eight forms of proposition adopted by De Morgan as the basis of his system partially differ from those which Hamilton derived from the quantified predicate. The general character of De Morgans development of logical forms was wholly peculiar and original on his part. Late in 1847 De Morgan published his principal logical treatise, called Formal Logic, or the Calculus of Inference, Necessary and Probable. This contains a reprint of the First Notions, an elaborate development of his doctrine of the syllogism, and of the numerical definite syllogism, together with chapters of great interest on probability, induction, old logical terms and fallacies. The severity of the treatise is relieved by characteristic touches of humour, and by quaint anecdotes and allusions furnished from his wide reading and perfect memory. There followed at intervals, in the years 1850, 1858,1860 and 1863, a series of four elaborate memoirs on the Syllogism, printed in volumes ix. nd x. of the Cambridge Philosophical Transactions. These papers taken together constitute a great treatise on logic, in which he substituted improved systems of notation, and developed a new logic of relations, and a new onymatic system of logical expression. In 1860 De Morgan endeavoured to render their contents better known by publishing a [[Syllabus]] of a Proposed System of Logic, from which may be obtained a good idea of his symbolic system, but the more readable and interesting discussions contained in the memoirs are of necessity omitted. The article Logic in the English Cyclopaedia (1860) completes the list of his logical publications. Throughout his logical writings De Morgan was led by the idea that the followers of the two great branches of exact science, logic and mathematics, had made blunders, the logicians in neglecting mathematics, and the mathematicians in neglecting logic. He endeavoured to reconcile them, and in the attempt showed how many errors an acute mathematician could detect in logical writings, and how large a field there was for discovery. But it may be doubted whether De Morgans own system, horrent with mysterious spiculae, as Hamilton aptly described it, is fitted to exhibit the real analogy between quantitative and qualitative reasoning, which is rather to be sought in the logical works of Boole. Perhaps the largest part, in volume, of De Morgans writings remains still to be briefly mentioned; it consists of detached articles contributed to various periodical or composite works. During the years 1833-1843 he contributed very largely to the first edition of the [[Penny]] Cyclopaedia, writing chiefly on mathematics, astronomy, physics and biography. His articles of various length cannot be less in number than 850, and they have been estimated to constitute a sixth part of the whole Cyclopaedia, of which they formed perhaps the most valuable portion. He also wrote biographies of Sir Isaac Newton and Edmund Halley for Knights British Worthies, various notices of scientific men for the [[Gallery]] of Portraits, and for the uncompleted Biographical Dictionary of the Useful Knowledge Society, and at least seven articles in Smiths Dictionary of Greek and Roman Biography. Some of De Morgans most interesting and useful minor writings are to be found in the Companions to the British Almanack, to which he contributed without fail one article each year from 1831 up to 1857 inclusive. In these carefully written papers he treats a great variety of topics relating to astronomy, chronology, decimal coinage, life assurance, bibliography and the history of science. Most of them are as valuable now as when written. Among De Morgans miscellaneous writings may be mentioned his Explanation of the Gnomonic Projection of the Sphere, 1836, including a description of the maps of the stars, published by the Useful Know ledge Society; his Treatise on the Globes, Celestial and Terrestrial,1845, and his remarkable [[Book]] of Almanacks (2nd edition, 1871), which contains a series of thirty-five almanacs, so arranged with indices of reference, that the almanac for any year, whether in old style or new, from any epoch, ancient or modern, up to A.  D. 2000, may be found without difficulty, means being added for verifying the almanac and also for discovering the days of new and full moon from 2000 B. c. up to A. D. 2000. De Morgan expressly draws attention to the fact that the plan of this book was that of L. B. Francoeur and J. Ferguson, but the plan was developed by one who was an unrivalled master of all the intricacies of chronology. The two best tables of logarithms, the small five-figure tables of the Useful Knowledge Society 1839 and 1857), and Shroens Seven Figure-Table (5th ed. , 1865), were printed under De Morgans superintendence. Several works edited by him will be found mentioned in the British Museum Catalogue. He made numerous anonymous contributions through a long series of years to the Athenaeum, and to Notes and Queries, and occasionally to The North British Review, Macmillans Magazine, c.  Considerable labour was spent by De Morgan upon the subject of decimal coinage. He was a great advocate of the pound and mil scheme. His evidence on this subject was sought by the Royal Commission, and, besides constantly supporting the Decimal Association in periodical publications, he published several separate pamphlets on the subject. In 1866 his life became clouded by the circumstances which led him to abandon the institution so long the scene of his labours. The refusal of the council to accept the recommendation of the senate, that they should appoint an eminent Unitarian minister to the professorship of logic and mental philosophy, revived all De Morgans sensitiveness on the subject of sectarian freedom; and, though his feelings were doubtless excessive, there is no doubt that gloom was thrown over his life, intensified in 1867 by the loss of his son George Campbell De Morgan, a young man of the highest scientific promise, whose name, as De Morgan expressly wished, will long be connected with the London Mathematical Society, of which he was one of the founders. From this time De Morgan rapidly fell into ill-health, previously almost unknown to him, dying on the 18th of March 1871. An interesting and truthful sketch of his life will be found in the Monthly Notices of the Royal Astronomical Society for the 9th of February 1872, vol. xxii. p. 112, written by A. C. Ranyard, who says, He was the kindliest, as well as the most learned of men benignant to every one who approached him, never forgetting the claims which weakness has on strength. De Morgan left no published indications of his opinions on religious questions, in regard to which he was extremely reticent. He seldom or never entered a place of worship, and declared that he could not listen to a sermon, a circumstance perhaps due to the extremely strict religious discipline under which he was brought up. Nevertheless there is reason to believe that he VIII. 1 a was of a deeply religious disposition. Like M. Faraday and Sir I.  Newton he entertained a confident belief in Providence, founded not on any tenuous inference, but on personal feeling. His hope of a future life also was vivid to the last. George Boole George Booles father, John Boole (1779–1848), was a tradesman of limited means, but of studious character and active mind. Being especially interested in mathematical science and logic, the father gave his son his first lessons; but the extraordinary mathematical talents of George Boole did not manifest themselves in early life. At first, his favorite subject was classics. It was not until his successful establishment of a school at Lincoln, its removal to Waddington, and later his appointment in 1849 as the first professor of mathematics of then Queens College, Cork in Ireland (now University College Cork, where the library, underground lecture theatre complex and the Boole Centre for Research in Informatics are named in his honour) that his mathematical skills were fully realized. In 1855 he married Mary Everest (niece of George Everest), who later, as Mrs. Boole, wrote several useful educational works on her husbands principles. To the broader public Boole was known only as the author of numerous abstruse papers on mathematical topics, and of three or four distinct publications that have become standard works. His earliest published paper was the Researches in the theory of analytical transformations, with a special application to the reduction of the general equation of the second order. printed in the Cambridge Mathematical Journal in February 1840 , and it led to a friendship between Boole and D. F. Gregory, the editor of the journal, which lasted until the premature death of the latter in 1844. A long list of Booles memoirs and detached papers, both on logical and mathematical topics, are found in the Catalogue of Scientific Memoirs published by the Royal Society, and in the supplementary volume on Differential Equations, edited by Isaac Todhunter. To the Cambridge Mathematical Journal and its successor, the Cambridge and Dublin Mathematical Journal, Boole contributed twenty-two articles in all. In the third and fourth series of the Philosophical Magazine are found sixteen papers. The Royal Society printed six important memoirs in the Philosophical Transactions, and a few other memoirs are to be found in the Transactions of the Royal Society of Edinburgh and of the Royal Irish Academy, in the Bulletin de lAcademie de St-Petersbourg for 1862 (under the name G Boldt, vol. iv. pp. 198–215), and in Crelles Journal. Also included is a paper on the mathematical basis of logic, published in the Mechanics Magazine in 1848. The works of Boole are thus contained in about fifty scattered articles and a few separate publications. Only two systematic treatises on mathematical subjects were completed by Boole during his lifetime. The well-known Treatise on Differential Equations appeared in 1859, and was followed, the next year, by a Treatise on the Calculus of Finite Differences, designed to serve as a sequel to the former work. These treatises are valuable contributions to the important branches of mathematics in question. To a certain extent these works embody the more important discoveries of their author. In the sixteenth and seventeenth chapters of the Differential Equations we find, for instance, an account of the general symbolic method, the bold and skilful employment of which led to Booles chief discoveries, and of a general method in analysis, originally described in his famous memoir printed in the Philosophical Transactions for 1844. Boole was one of the most eminent of those who perceived that the symbols of operation could be separated from those of quantity and treated as distinct objects of calculation. His principal characteristic was perfect confidence in any result obtained by the treatment of symbols in accordance with their primary laws and conditions, and an almost unrivalled skill and power in tracing out these results. During the last few years of his life Boole was constantly engaged in extending his researches with the object of producing a second edition of his Differential Equations much more complete than the first edition, and part of his last vacation was spent in the libraries of the Royal Society and the British Museum; but this new edition was never completed. Even the manuscripts left at his death were so incomplete that Todhunter, into whose hands they were put, found it impossible to use them in the publication of a second edition of the original treatise, and printed them, in 1865, in a supplementary volume. With the exception of Augustus de Morgan, Boole was probably the first English mathematician since the time of John Wallis who had also written upon logic. His novel views of logical method were due to the same profound confidence in symbolic reasoning to which he had successfully trusted in mathematical investigation. Speculations concerning a calculus of reasoning had at different times occupied Booles thoughts, but it was not till the spring of 1847 that he put his ideas into the pamphlet called Mathematical Analysis of Logic. Boole afterwards regarded this as a hasty and imperfect exposition of his logical system, and he desired that his much larger work, An Investigation of the Laws of Thought, on Which are Founded the Mathematical Theories of Logic and Probabilities (1854), should alone be considered as containing a mature statement of his views. Nevertheless, there is a charm of originality about his earlier logical work that is easy to appreciate.

Comparing The Adventures of Huckleberry Finn and Tom Sawyer :: comparison compare contrast essays

The Adventures of Huckleberry Finn and Tom Sawyer Huckleberry Finn and Tom Sawyer are the best of friends with remarkably different personalities. Each brings their unique characteristics into this comical friendship giving the novel numerous amusing passages. Throughout the tale, Tom is often the leader while Huck is the reluctant follower. It doesn't matter that Tom's ideas are ridiculous and extravagant, and Huck's are simple and practical, together they always proceed with Tom's imaginative plans. In contrast to Tom's great imagination and creativity, Huck is humorless and literal minded. Tom's imaginativeness comes only from knowledge he has gained through books. Huck, on the other hand, actually lives out the fantasies Tom can only imagine. Tom Sawyer, already civilized, follows the values and beliefs of society. Due to these convictions, Tom always abides by the laws. For these reasons, Tom would never have helped free Jim unless he knew that Jim had already been freed. Conversely, Huck Finn rejects the philosophy of political beliefs for the fear of becoming civilized. He usually runs away at the first notion of him becoming "sivilized." Huck is able to function in any society with the help of his adaptability and survival skills. He is able to go from the freedom of the raft, to the perceived harshness of civilization, and back again with ease. Although Tom has been able to slip past Death's grip so far, his chances of escaping may not always work out to his liking. Of the two, Huck will always be the survivor in life. Together this pair achieves their goals because of their intelligence and witty personalities. They have the ability to put the knowledge they obtain into their every day lives. They are two adventurous souls in search of fresh and exhilarating escapades. Their ages united with their exceptional education keeps them on their toes.

Miracles and Science Essay

1. Introduction: Miracles as violations of the laws of nature Unbelievable, isn’t it, that there are still students at this university who believe in stories from the Bible, said Martin, an older colleague, at one of the formal dinners around which the traditional life of Oxford University revolves. But Martin, I answered, their faith probably doesn’t differ much from mine. I can still see his face go pale while he nearly choked on his glass of St. Emilion Grand Cru Classà ©: How can you believe in such things nowadays – Walking on water, a resurrection from the dead? Those are miracles, and aren’t you a scientist? Oh, how interesting, say John and Ruth, a couple that I have just met at the end of a church service. You are a scientist. They look a bit unsure of what to say next and John blurts out, I read recently that we still don’t understand how birds can fly so many miles to the south and yet return to exactly the same place each summer. Scientists can’t explain this; it is a miracle, don’t you think? I never quite know what to say next in such conversations. Perhaps nine years of living in Britain have made me too sensitive to that most cardinal of English social sins – causing embarrassment. But there is more to it than that. Behind these statements lies a tangle of complex intellectual issues related to the definition and scope of science, the nature of God’s action in the world, and the reliability and interpretation of the Bible. These have exercised many of greatest minds in history: The debate between atheism and religious belief has gone on for centuries, and just about every aspect of it has been explored to the point where even philosophers seem bored with it. The outcome is stalemate. 1 So says my Oxford colleague Alister McGrath. Although these subtleties are well known to philosophers and historians of  science, public discourse on science and religion often seems blissfully unaware of them. 2 Everyone brings a set of presuppositions to the table. To make progress, these should first be brought out into the open. Without time for an honest conversation in which we can listen to each other in depth, I won’t know exactly what Martin, John, or Ruth’s presuppositions are. But, for the sake of this essay, I will be a bit presumptuous and venture a guess. My guess would be that, although both seem to be on opposite sides of a vast divide, they are in fact influenced by a similar perspective on science and miracles, one first laid down by the great sceptical Scottish philosopher David Hume, who wrote: A miracle is a violation of the laws of nature, and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined. This language of â€Å"miracles as violations of the laws of nature† has framed the debate ever since. Martin, John and Ruth, perhaps without realizing it, are living under the long shadow of David Hume. Martin may think that science is the only reliable route to gaining knowledge about the world, and that, since belief in miracles is obviously unscientific, such belief must ipso facto be false. John and Ruth may feel a similar tension between science and miracles, and are therefore encouraged by any natural process that seems inexplicable. Weakening the power of science would seem to strengthen the case for God acting in the world: If we know that today God miraculously steers a bird back to its original habitat after a long return flight to the south, then it is easier to believe that 2000 years ago he turned water into wine at a wedding in Cana. Now, as a Christian scientist who believes in the miracles of the Bible, I take issue with both of the views above. But to explain this better, I need to first take a step back and answer two critical questions: What do I mean by science, and what does  the Bible say about miracles? 2. Defining Science The problem of deciding where to draw the lines around science has vexed generations of philosophers. Like many unsolved issues, it has been given its own name—â€Å"the demarcation problem.† Although one can determine with some degree of consensus what the extremes of the science/non-science continuum are, exactly where the boundary lies is fuzzy. This doesn’t mean, however, that we cannot recognize science when we see it4, but rather that a watertight definition is difficult to create. The old fashioned idea (still taught in many schools) that scientific practice follows a well-defined linear process—first make an observation, then state a hypothesis, and then test that hypothesis—is certainly far too simple. Science as a tapestry Rather than attempt to come up with a careful and precise definition of science or scientific practice, I will instead resort to a favorite metaphor of mine. It originates with one of my former teachers at Cornell, the p hysicist David Mermin, who describes science as a â€Å"tapestry† woven together from many threads (experimental results, interpretations, explanations, etc.).5 It is only when one examines the tapestry as a whole that it will (or will not) make a convincing pattern. Creating scientific tapestries is a collective endeavor building on mutual trust and the communal experience of what kinds of arguments and evidence are likely to stand the test of time. In part because the skill of weaving reliable scientific tapestries relies on subtle judgements, a young scientist may work for years as an apprentice of older and more experienced practitioners before branching out on his own. In this process there are many parallels with the guilds of old. I am fond of this metaphor because it describes what I think I experience from the inside as a scientist. Moreover, it also emphasizes the importance of coherence and consistency when I weave together arguments and data to make an â€Å"inference to a best explanation.†6 The strong communal element inherent in scientific practice has at times been seized upon by sociologists of science to argue that s cientific knowledge is just one more type of human construct with no greater  claim on reality than any other form of knowledge. But scientists as a whole have reacted to this proposition in a negative way.7 Although they agree that all kinds of economic, historical and social factors do play a role in the formation of scientific theories, they would argue that, in the long run, the scientific process does lead to reliable knowledge about the world. The view of nature embraced by most scientists that I know could be described as critical realism. They are realists because they believe that there is a world out there that is independent of our making. The adjective â€Å"critical† is added because they recognize that extracting knowledge about that world is not always straightforward. Thus, the primary role of the collective nature of the scientific process is to provide a network of error-correcting mechanisms that prevent us from fooling ourselves. The continual testing against nature refines and filters out competing scientific theories, leading to advances in the strength and reliability of our scien tific knowledge tapestries. Although there are many commonalities in the ways that scientists in distinct fields assemble their tapestry arguments, there can also be subtle differences. These differences are foisted on us in part by the types of problems that each field attempts to address. For example, as a theoretical physicist I’ve been trained in a tradition of what the Nobel Laureate Eugene Wigner called â€Å"the unreasonable effectiveness of mathematics:† The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning.8 We believe, based on a history of spectacular success, that mathematical consistency among threads is a key indicator of strong tapestries.9 These days, I spend much of my time interacting with biologists who tend to view my confidence  in the ability of theoretical models to extract knowledge about the physical world with great suspicion.10 I, on the other hand, am often instinctively sceptical of the huge error bars that can afflict their data.11 To a large degree, these cultural differences are forced on us by the kinds of questions we study. My reaction above arises because physics is self-limiting. As a community we simply don’t deal with problems of the same level of complexity that biology does. If an experiment is too messy we will often define it away by declaring â€Å"that isn’t physics,† and move on. Similarly, molecular biologists can afford to be more selective about their data than medical scientists or psychologists can.12 But, despite these cultural differences, which can lead to heated and sometimes frustrating discussion, we do agree on a number of ground rules for defining what makes a tapestry strong. For example, what we either predict or measure should be repeatable. If I claim to see an effect in an experiment, someone else in a different lab should be able to reliably measure the same effect.13 That simple requirement has many ramifications for the types of problems we are able to address The limits of science There are many questions that simply are not amenable to purely scientific analysis. A very lucid discussion of this issue can be found in the book The Limits of Science by Nobel Prize winner (and atheist) Sir Peter Medawar, who wrote: That there is indeed a limit upon science is made very likely by the existence of questions that science cannot answer and that no conceivable advance of science would empower it to answer†¦ It is not to science, therefore but to metaphysics, imaginative literature or religion that we must turn for answers to questions having to do with first and last things. and Science is a great and glorious enterprise – the most successful, I argue, that human beings have ever engaged in. To reproach it for its inability to answer all the questions we should like to put to it is no more sensible than to reproach a railway locomotive for not flying or, in general, not performing any other operation for which it was not designed.14 Science’s great power derives from its self-imposed limits. It is wrong to ask it to pronounce on issues outside its jurisdiction. In fact, the most important decisions in life cannot be addressed solely by the scientific method, nor do people really live as if they can. In the words of Sir John Polkinghorne, former professor of Mathematical Physics at Cambridge and Anglican priest: We are entitled to require a consistency between what people write in their studies and the way in which they live their lives. I submit that no-one lives as if science were enough. Our account of the world must be rich enough – have a thick enough texture and a sufficiently generous rationality – to contain the total spectrum of human meeting with reality. But just because we don’t live life by the scientific method doesn’t mean that the only alternative is irrationality. For example, if I were to decide to get married, a truly irrational approach would be to pick a random woman off the street. Instead, assuming I find a potentially willing partner, it is wise to go through a period of courtship during which we get to know each other. We may also ask for the opinion of wise friends. There are helpful counseling programs with compatibility lists, etc. that, in fact, often use knowledge that scientific techniques have extracted from our collective experience and wisdom. But at the end of the day I can’t demand scientific certainty before deciding to marry someone. Nor is it wise to perform repeatable experiments! I need to make a volitional step because there are aspects of marriage that I can only see from the inside.15 Another example of a method used to obtain knowledge is the legal process which, although it is a tightly organized system, is not strictly scientific. Similarly, a historian will use a combination of evidence (e.g. manuscripts) and understanding about the thinking patterns of a particular era to make informed judgements about what happened in the past. Clearly, this big question of how to extract reliable  information about the world, how to separate fact from mere opinion, is indeed a very difficult and important one. 3. Miracles and the Bible How can we then judge whether or not the miracles of the Bible are reliable? Since the word miracle has taken on so many different meanings, it is important to first examine the biblical language. The New Testament predominantly uses three words for miracle: ï‚ ·teras, a wonder ï‚ ·dunamis, an act of power ï‚ ·semeion, a sign Sometimes it combines all three, as in Acts 2:22: Men of Israel, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles (dunamis), wonders (teras) and signs (semeion), which God did among you through him, as you yourselves know. The word teras (wonder) is almost always used together with one of the other words, emphasizing that the main point of biblical miracles is not to merely elicit amazement but rather to serve a higher theological purpose. For this reason, biblical miracles cannot be understood outside of the theological context within which they occur. They are not anomalous events. This principle provides a key to the proper assessment of their validity. Nature is what God does Miracles happen against a backdrop. In this context, it is illuminating to see how the Bible describes God’s action in the natural world. For example in Psalm 104, that great poem about nature, we read, He makes springs pour water into the ravines, it flows between the mountains The first part of this verse refers to God’s direct action while the second part suggests that water flows through its own natural properties. Read the Psalm for yourself and notice how fluidly the point of view changes back and forth between what we might call the laws of nature and the direct action of God. Such dual descriptions can be found throughout the Bible. The New Testament is even more explicit: The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. (Hebrews 1:3)  and He is before all things, and in him all th ings hold together (Col 1:17) In other words, if God were to stop sustaining all things by his powerful word, the world would stop existing. That is why, when describing nature, the Bible so easily switches perspectives depending on whether it is emphasizing the regular behavior of natural phenomena, or their origin in God’s providential sustenance. So, as St. Augustine might say, Nature is what [God] does.16 Augustine doesn’t mean that nature is the same as God (pantheism), for, as he also argued, God operates outside of space and time. Nevertheless, and this is a very subtle point, 17 a case can be made for ascribing some independent causal power to the laws of nature. On the other hand, there is no room within a robust biblical theism for the opposite deistic notion that God started the world and then left it to run on its own, completely independently, because descriptions of God’s continuous care for creation are found throughout Scripture: Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from the will of your Father. And even the very hairs of your head are all numbered. (Matthew 10:29,30) As Christian thinkers throughout the Middle Ages wrestled with the questions of miracles and God’s action in the world, the following ideas emerged: if the regularities of nature are a manifestation of the sustenance of God then one would expect them to be trustworthy and consistent, rather than capricious. The regular behavior of nature could be viewed as the â€Å"customs of the Creator† as it were. Christians glorify God by studying these â€Å"laws of nature.† A strong case can be made that such theological realizations helped pave the way for the rise of modern science.18 By the time the Royal Society of London, the world’s first scientific society, was founded in 1660, Christian thinkers like the metaphysical poet John Donne, then dean of St. Paul’s Cathedral in London, could write: the ordinary things in Nature, would be greater miracles than the extraordinary, which we  admire most, if they were done but once†¦ only the daily doing takes off the admiration.19 God of the gaps A similar sentiment lies behind a famous exchange between those old adversaries, Gottfried Wilhelm Leibniz and Sir Isaac Newton. The latter noticed that the orbits of the planets did not appear to be stable when calculated over long periods, and postulated that the solar system needed occasional â€Å"reformation† by God. Leibniz objected that,  if God had to remedy the defects of His creation, this was surely to demean his craftsmanship. 20 In other words, the regular sustaining activity of God, as evidenced by natural laws, should be sufficient t o explain the regular behaviour of the solar system, without the need for additional ad-hoc interventions. Making it right the first time is more glorious than having to fix it later. In the same context, Leibniz also emphasised the theological nature of miracles: And I hold, that when God works miracles, he does not do it in order to supply the wants of nature, but those of grace. Whoever thinks otherwise, must needs have a very mean notion of the wisdom and power of God.21 A more modern version of Leibniz’s general objection can be found in a famous statement by Charles Coulson, the first Oxford professor of Theoretical Chemistry who wrote, When we come to the scientifically unknown, our correct policy is not to rejoice because we have found God; it is to become better scientists.22 He popularized the phrase â€Å"God of the gaps† for those who, perhaps like John and Ruth, think that God is found primarily in the lacunas of our scientific understanding. Two sorts of miracles Science, as well as tools from historical disciplines, can be brought to bear on biblical miracles. For example they can be split into those that are examples of providential timing (type i miracles) and those that can only be viewed as directly violating physical cause-effect  relationships (type ii miracles). An example of a possible type i miracle would be the crossing of the river Jordan by the people of Israel: Now the Jordan is at flood stage all during harvest. Yet as soon as the priests who carried the ark reached the Jordan and their feet touched the water’s edge, the water from upstream stopped flowing. It piled up in a heap a great distance away, at a town called Adam in the vicinity of Zarethan, while the water flowing down to the Sea of the Arabah (the Salt Sea) was completely cut off. So the people crossed over opposite Jericho. (Joshua 3:15,16) Colin Humphreys, Cambridge professor of material science, has studied this miracle in great detail 23 and notes that the text supplies a number of unusual clues, including the fact that the water was blocked up a great distance away at a particular town. He has identified this with a location where the Jordan has been known to temporarily dam up when strong earthquakes cause mudslides (most recently in 1927). For many scientists, the fact that God is working through natural processes makes the miracle more palatable: The scientist, even when he is a believer, is bound to try as far as possible to reduce miracles to regularities: the believer, even when he is a scientist, discovers miracles in the most familiar things.24 Of course this doesn’t take away from the fact that there was remarkable timing involved. Perhaps the attraction of this description comes in part because there is a direct corollary with the very common experience of â€Å"providential timing† of events, which believers attribute to God’s working.25 There are also miracles in the Bible that defy description in terms of current science. Perhaps the most significant of these is the resurrection of Jesus Christ. If anything, science has strengthened the case for this not being a type i miracle. For example, in John 19:34 we read: Instead, one of the soldiers pierced Jesus’ side with a spear, bringing a sudden flow of blood and water. Modern medicine suggests that this is clear evidence that the pericardium, a membrane around the heart, was pierced, confirming that he was in fact dead. The more we know about the processes of decay that set in after death, the less likely it appears that Jesus could have risen from the dead by any natural means. Rather, science strengthens the case that if Jesus did indeed rise from the dead, the event must have occurred through a direct injection of supernatural power into the web of cause and effect that undergirds our physical world – it was a type ii miracle. Of course the resurrection is central to Christian teaching: And if Christ has not been raised, our preaching is useless and so is your faith. (I Corinthians 15:14) Given that almost every great Christian thinker in history has emphasized the fact that miracles must be understood within the context of a theological purpose, perhaps one could invert this argument and say that it is not surprising that the central eve nt in history would be miraculous. 26 So where has this argument brought us? I have argued that the precise relationship between miracles and science has been the subject of a long and unresolved debate with strands reaching back to the early Church fathers. Theologians wrestle with questions that concern the differences between God’s regular sustaining action and His special non-repeating actions, i.e. miracles, and how these fit in with redemptive purpose. There is a link to the question of demarcation in science, since within a robust biblical theism the regular working of God’s action, the â€Å"customs of the Creator† (or natural laws) are, almost by design, amenable to scientific analysis. Biblical miracles, in contrast, are always linked to special theological purpose and are therefore, almost by definition, non-repeatable and a-scientific. 4. The decisive significance of worldviews If Martin and I would have time to get this far in conversation, I’m sure we would have swiftly passed th e red herring of natural science being the touchstone upon which to examine biblical miracles. But Martin could point out that Hume made a number of other arguments against miracles, namely: Witness testimony is often suspect. ï‚ ·Stories get exaggerated in the retelling. Miracles are chiefly seen among ignorant and barbarous people. ï‚ ·Rival religions also have miracle stories, so they cancel each other out. These arguments are substantial, and I refer to footnote 3 for an introduction to the voluminous literature they have inspired. However, we can take a little stab at the first two objections. It is true that witness testimony cannot always be trusted and that stories change with time. But these are the same problems that face legal systems and historians. Nonetheless, we can employ the tools of these professions to examine biblical miracles. Take, for example, the resurrection of Jesus Christ. There is significant extrabiblical historical evidence that he indeed lived. Much has been written about the general trustworthiness of the Gospels. For example, there is much internal evidence, in both the style and content of the narratives, that the writers themselve s were convinced that Jesus did indeed rise from the dead. Tradition holds that 11 of the 12 original apostles were martyred for this belief that turned a group of cowards into a people who â€Å"turned the world upside down.† Although it is well beyond the scope of this essay, a very strong case for the plausibility of the resurrection can be made.27 Similar analysis can be brought to bear on other miracle claims, including those of other religions. After all, every meaningful system of thought must be open to careful scrutiny. But I suspect that often, underneath the surface, it is really the third argument that carries the most persuasive force. In part because history is littered with claims for the miraculous that seem bizarre, or smack of superstition, and in part because the incredible advances of modern science and technology inspire awe, we can intensely feel the attraction of identifying with the latter and not the former. This disposition is exemplified in the following quote by the theologian Rudolph Bultmann, a man famous for his attempts to de-mythologize the New Testament: It is impossible to use electric light and the wireless and to avail ourselves of modern medical and surgical discoveries, and at the same time to believe in the New Testament world of spirits and miracles.28 By getting rid of the miracle stories in the Bible,  Bultmann and his followers hoped to make the Christian story more palatable to modern man. Although I recognize the emotional weight of this sentiment, I am not convinced that it is an intellectually coherent approach, mainly for reasons of self-consistency. If the New Testamentitself asserts, both directly and indirectly, that the historicity of the resurrection is foundational to Christianity, then it would seem to stand or fall by that fact. As a physicist, I have a natural penchant for wanting to see how an idea relates to more basic principles. And to analyze the validity of a quote like the one above, we must take a cold hard look at our fundamental presuppositions. In the words of John Polkinghorne: If we are to understand the nature of reality, we have only two possible starting points: either the brute fact of the physical world or the brute fact of a divine will and purpose behind that physical world.29 Where does each of those two fundamental starting points take us? When we use them to construct a worldview, what kind of sense does it make of experience, morality, truth, beauty, and our place in the world? These are not easy questions. There is so much mystery around us. Perhaps the best way to move forward would be to borrow Mermin’s tapestry analogy and carefully investigate whether the different threads of historical evidence, philosophical consistency, and personal knowledge can be woven together into a worldview that is robust. In particular, does our tapestry posses those qualities of coherence and (surprising) fruitfulness that characterise the best scientific tapestries? If I start from the brute facts of nature, I personally am unable to construct a tapestry that is both rigorous and rich enough to make sufficient sense of the world. By contrast, if I assume a divine will and purpose behind the world I believe that I can construct a much more compelling tapesty that incorporates all of the threads of human  existence. Within that purposeful world, the case for Christianity is much more persuasive. To use a famous quote from C.S. Lewis: I believe in Christianity as I believe that the Sun has risen-not only because I see it, but because by it, I see everything else.30 It is the sum total of all those arguments that convinces me of the veracity of biblical miracles. Nevertheless, I recognize that no matter how cogent, say, the historical evidence for the resurrection is, if I start from a different worldview, as Martin and Rudolph Bultmann do, then it will be virtually impossible to accept the existence of biblical miracles. (In the end I think this is what Hume is really saying). Miracles cannot be interpreted independently from the theological context in which they function. They are part of a package deal. I don’t know what Martin would make of all that. We would surely need more than one glass of wine to complete this discussion (but wouldn’t it be fun?). 5. Conclusion Finally, what would I say to John and Ruth? If they are like many Christians I know, they might feel a slight uneasiness with science, a subconscious fear fed by the pontifications of some popularizers who seem keen to equate science with atheism.31 So perhaps I would first point out the obvious limits of science. But then I might tell the story of Leibniz and Newton’s exchange, and point out that Newton was a good enough theologian not to turn the alleged instability of the planets into a God of the gaps argument. Similarly, if it is true that we don’t yet understand how birds can navigate so accurately over large distances, then surely it would bring more glory to God to search for the mechanisms by which such remarkable feats are accomplished: It is the glory of God to conceal a matter; to search out a matter is the glory of kings. Proverbs 25:2 Perhaps because evolution has been a particularly favorite bludgeon of the science = atheism cabal, a Christian mini-industry has sprung up to debunk it. Unfortunately, this only feeds the public misperception that the core of the conflict between science and faith concerns scientific mechanism (evolution did or did not occur) rather than one of the philosophy and interpretation of science. God could, of course, have regularly used miracles to create throughout the time-span of natural history. He is free. But whether he did so in natural history is fundamentally a question of Biblical interpretation. 32 Surely it is even more glorious if God could design a physical system that creates itself through the regularities of his sustaining action. Like many of my Christian scientific colleagues who hold to a high view of Scripture, I believe the biblical text allows itself to be interpreted in this way, that sentient beings arose primarily through the ordinary â€Å"customs of the Creato r,† and that moreover it glorifies God to seek to understand these patterns.33 John and Ruth might then ask: if I emphasize the integrity of the regular action of God in sustaining the universe, and even in creating us, then why should miracles occur at all? Can they occur today? Rather than answer that theological question directly, let me resort to a musical analogy borrowed from Colin Humphreys. Suppose you are watching a pianist play a classical piece. You will notice that there are certain notes that he plays, and certain ones that he never does. The choice of notes is constrained because the music is being played in a particular key signature. But then, occasionally he may break this rule and play an unusual note. Musicians call these accidentals, and a composer can put them in wherever she likes (although if there are too many the music would sound strange). As Humphreys puts it, If he is a great composer, the accidentals will never be used capriciously: they will always make better music. It is the accidentals which contribute to making the piece of music great. The analogy with how God operates is clear: God created and upholds the universe but, like the great composer, he is free to override his own rules. However, if he is a c onsistent God, it must make more sense than less for him to override his rules.34 Notes 1. 2. 3. Alister McGrath, Dawkins’ God: Genes, Memes and the Meaning of Life, (Blackwell, Oxford 2005) p 92. A good example of this is Richard Dawkins, The God Delusion, (Bantam, London 2006) David Hume, Enquiry Concerning Human Understanding and Concerning the Principles of Morals, (1748). Hume’s argument has often been criticized for being self-referential. He at first presupposes that no reasonable person can believe that the laws of nature can be violated, and then concludes that miracles cannot occur because he defines them as violations of the laws of nature. Note that this analysis is not accepted by all commentators. Colin Brown, Miracles and the Critical Mind, (Paternoster, Exeter, 1984) provides a lucid overview of the debate. See also John Earman, Hume’s Abject Failure. The Argument against Miracles (Oxford University Press, Oxford 2000) for a critical view, and Peter Harrison, â€Å"Miracles, Early Modern Science, and Rational Religion†, Church History 75 (3) pp. 493-511 (2006) for an interesting historical perspective. I am reminded of a famous quote by US Supreme Court judge Potter Stewart who, when asked to distinguish between art and pornography, noted that although it was hard to define: â€Å"I know it when I see it† (Jacobellis v. Ohio (1964)). N. David Mermin, â€Å"The Golemization of Relativity†, Physics Today 49, 11–13 (1996) Peter Lipton, Inference to the Best Explanation, (Routledge, London, 2004) In the 1990’s this tension between sociologists and the scientific community erupted into the so-called ‘Science Wars’. For a good overview, see e.g. J. A. Labinger and H. Collins (eds), The One Culture? A Conversation about Science, (University of Chicago Press, Chicago, 2001). Quote from Nobel Prize winner E. Wigner, â€Å"The Unreasonable Effectiveness of Mathematics in the Natural Sciences†, Communications in Pure and Applied Mathematics, vol. 13, No. I (February 1960). An iconic example would be Paul Dirac’s 1928 prediction of anti-ma tter, which he showed to be necessary to satisfy the mathematical consistency constraints  imposed by combining quantum mechanics and special relativity for electrons. See P.A.M. Dirac, Proc. Roy. Soc. A, 117, 610 (1928). The cultural differences between more mathematically minded physical scientists and more empirically minded biological scientists are discussed by Evelyn Fox Keller, in a fascinating book: Making Sense of Life: Explaining Biological Development with Models, Metaphors, and Machines, Harvard University Press, Boston (2002). Such instinctive reactions are what make interdisciplinary research so difficult. Clearly biology has been incredibly successful despite its differences with my scientific culture. I also suggest that as the questions we ask become difficult (often the case for applied subjects like medicine), the tapestries, by necessity, become more fragile. I realize that this is more subtle for historical sciences like geology and cosmology (we have, for example, only observed one universe). Nevertheless, even in these fields, parallel concepts apply. P.B. Medawar, The Limits of Science, Oxford University Press, Oxford (1987) . There are interesting analogies here to making a religious commitment. Christians would argue that important aspects of the Christian life can only be understood and experienced from within a relationship with Christ. That is not to say that a step of faith is just a blind leap in the dark. It should be a decision that is informed by careful thinking and weighing of evidence. But it is more than just that.

Hooykaas, op cit One could argue that God must nevertheless employ divine action to set up the conditions necessary for a type i miracle to occur at the right time. In that sense both kinds of miracles may involve violations of normal physical cause-effect relations, but in type i this is more hidden. Note that I am not arguing that miracles  break ultimate cause-effect relationships. Within a divine economy, they may make perfect causal sense. Language like â€Å"violation of physical cause-effect† reflects our limited access to the mind of God.
