Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

Research
–
It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field, to test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of research are documentation, discovery, interpretation, or the research and development of methods. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences, there are several forms of research, scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological, etc. The earliest recorded use of the term was in 1577, Research has been defined in a number of different ways. Another definition of research is given by John W. Creswell and it consists of three steps, pose a question, collect data to answer the question, and present an answer to the question. Original research is research that is not exclusively based on a summary and this material is of a primary source character. The purpose of the research is to produce new knowledge. Original research can take a number of forms, depending on the discipline it pertains to, in analytical work, there are typically some new mathematical results produced, or a new way of approaching an existing problem. The degree of originality of the research is among major criteria for articles to be published in academic journals, graduate students are commonly required to perform original research as part of a dissertation. Scientific research is a way of gathering data and harnessing curiosity. This research provides scientific information and theories for the explanation of the nature, scientific research is funded by public authorities, by charitable organizations and by private groups, including many companies. Scientific research can be subdivided into different classifications according to their academic, Research in the humanities involves different methods such as for example hermeneutics and semiotics. Humanities scholars usually do not search for the correct answer to a question. Context is always important, and context can be social, historical, political, cultural, an example of research in the humanities is historical research, which is embodied in historical method. Historians use primary sources and other evidence to systematically investigate a topic, other studies aim to merely examine the occurrence of behaviours in societies and communities, without particularly looking for reasons or motivations to explain these. These studies may be qualitative or quantitative, and can use a variety of approaches, Artistic research, also seen as practice-based research, can take form when creative works are considered both the research and the object of research itself. It is the body of thought which offers an alternative to purely scientific methods in research in its search for knowledge

Engineer
–
Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin words ingeniare and ingenium, the work of engineers forms the link between scientific discoveries and their subsequent applications to human and business needs and quality of life. His/her work is predominantly intellectual and varied and not of a mental or physical character. It requires the exercise of original thought and judgement and the ability to supervise the technical, he/she is thus placed in a position to make contributions to the development of engineering science or its applications. In due time he/she will be able to give authoritative technical advice, much of an engineers time is spent on researching, locating, applying, and transferring information. Indeed, research suggests engineers spend 56% of their time engaged in various information behaviours, Engineers must weigh different design choices on their merits and choose the solution that best matches the requirements. Their crucial and unique task is to identify, understand, Engineers apply techniques of engineering analysis in testing, production, or maintenance. Analytical engineers may supervise production in factories and elsewhere, determine the causes of a process failure and they also estimate the time and cost required to complete projects. Supervisory engineers are responsible for major components or entire projects, Engineering analysis involves the application of scientific analytic principles and processes to reveal the properties and state of the system, device or mechanism under study. Most engineers specialize in one or more engineering disciplines, numerous specialties are recognized by professional societies, and each of the major branches of engineering has numerous subdivisions. Civil engineering, for example, includes structural and transportation engineering and materials engineering include ceramic, metallurgical, mechanical engineering cuts across just about every discipline since its core essence is applied physics. Engineers also may specialize in one industry, such as vehicles, or in one type of technology. Several recent studies have investigated how engineers spend their time, that is, research suggests that there are several key themes present in engineers’ work, technical work, social work, computer-based work, information behaviours. Amongst other more detailed findings, a recent work sampling study found that engineers spend 62. 92% of their time engaged in work,40. 37% in social work. The time engineers spend engaged in activities is also reflected in the competencies required in engineering roles. There are many branches of engineering, each of which specializes in specific technologies, typically engineers will have deep knowledge in one area and basic knowledge in related areas. When developing a product, engineers work in interdisciplinary teams. For example, when building robots an engineering team will typically have at least three types of engineers, a mechanical engineer would design the body and actuators

Marketing
–
Marketing is the study and management of exchange relationships. Marketing is used to create the customer, to keep the customer, with the customer as the focus of its activities, it can be concluded that Marketing is one of the premier components of Business Management - the other being Innovation. Other services and management activities such as Operations, Human Resources, Accounting, Law, the term developed from the original meaning which referred literally to going to a market to buy or sell goods or services. The Chartered Institute of Marketing defines marketing as the management process responsible for identifying, anticipating and satisfying customer requirements profitably, a similar concept is the value-based marketing which states the role of marketing to contribute to increasing shareholder value. Marketing practice tended to be seen as an industry in the past. The overall process starts with marketing research and goes through market segmentation, business planning and execution, ending with pre and it is also related to many of the creative arts. The marketing literature is also adept at re-inventing itself and its vocabulary according to the times, the term marketing concept pertains to the fundamental premise of modern marketing. This concept proposes that in order to satisfy its organizational objectives, Marketing and marketing concepts are directly related. An orientation, in the context, relates to a perception or attitude a firm holds towards its product or service. There exist several common orientations, A firm employing a product orientation is chiefly concerned with the quality of its own product, a firm would also assume that as long as its product was of a high standard, people would buy and consume the product. A firm using a sales orientation focuses primarily on the selling/promotion of a particular product, consequently, this entails simply selling an already existing product, and using promotion techniques to attain the highest sales possible. Such an orientation may suit scenarios in which a firm holds dead stock, or otherwise sells a product that is in high demand, a firm focusing on a production orientation specializes in producing as much as possible of a given product or service. Thus, this signifies a firm exploiting economies of scale, until the minimum efficient scale is reached, a production orientation may be deployed when a high demand for a product or service exists, coupled with a good certainty that consumer tastes do not rapidly alter. The marketing orientation is perhaps the most common used in contemporary marketing. It involves a firm essentially basing its marketing plans around the marketing concept, the marketing orientation often has three prime facets, which are, A firm in the market economy can survive by producing goods that persons are willing and able to buy. Consequently, ascertaining consumer demand is vital for a firms future viability, in this sense, a firms marketing department is often seen as of prime importance within the functional level of an organization. Information from a marketing department would be used to guide the actions of other departments within the firm. As an example, a department could ascertain that consumers desired a new type of product

University
–
A university is an institution of higher education and research which grants academic degrees in various academic disciplines. Universities typically provide undergraduate education and postgraduate education, the word university is derived from the Latin universitas magistrorum et scholarium, which roughly means community of teachers and scholars. Universities were created in Italy and evolved from Cathedral schools for the clergy during the High Middle Ages, the original Latin word universitas refers in general to a number of persons associated into one body, a society, company, community, guild, corporation, etc. Like other guilds, they were self-regulating and determined the qualifications of their members, an important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the first university, the University of Bologna adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of academic freedom and this is now widely recognised internationally - on 18 September 1988,430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bolognas foundation. The number of universities signing the Magna Charta Universitatum continues to grow, the university is generally regarded as a formal institution that has its origin in the Medieval Christian setting. The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and it is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were founded by Kings or municipal administrations. In the early period, most new universities were founded from pre-existing schools. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries, the first universities in Europe with a form of corporate/guild structure were the University of Bologna, the University of Paris, and the University of Oxford. The students had all the power … and dominated the masters, princes and leaders of city governments perceived the potential benefits of having a scholarly expertise develop with the ability to address difficult problems and achieve desired ends. The emergence of humanism was essential to understanding of the possible utility of universities as well as the revival of interest in knowledge gained from ancient Greek texts. The rediscovery of Aristotles works–more than 3000 pages of it would eventually be translated–fuelled a spirit of inquiry into natural processes that had begun to emerge in the 12th century. Some scholars believe that these represented one of the most important document discoveries in Western intellectual history. Richard Dales, for instance, calls the discovery of Aristotles works a turning point in the history of Western thought and this became the primary mission of lecturers, and the expectation of students. The university culture developed differently in northern Europe than it did in the south, Latin was the language of the university, used for all texts, lectures, disputations and examinations. Professors lectured on the books of Aristotle for logic, natural philosophy, and metaphysics, while Hippocrates, Galen, outside of these commonalities, great differences separated north and south, primarily in subject matter

Science
–
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The formal sciences are often excluded as they do not depend on empirical observations, disciplines which use science, like engineering and medicine, may also be considered to be applied sciences. However, during the Islamic Golden Age foundations for the method were laid by Ibn al-Haytham in his Book of Optics. In the 17th and 18th centuries, scientists increasingly sought to formulate knowledge in terms of physical laws, over the course of the 19th century, the word science became increasingly associated with the scientific method itself as a disciplined way to study the natural world. It was during this time that scientific disciplines such as biology, chemistry, Science in a broad sense existed before the modern era and in many historical civilizations. Modern science is distinct in its approach and successful in its results, Science in its original sense was a word for a type of knowledge rather than a specialized word for the pursuit of such knowledge. In particular, it was the type of knowledge which people can communicate to each other, for example, knowledge about the working of natural things was gathered long before recorded history and led to the development of complex abstract thought. This is shown by the construction of calendars, techniques for making poisonous plants edible. For this reason, it is claimed these men were the first philosophers in the strict sense and they were mainly speculators or theorists, particularly interested in astronomy. In contrast, trying to use knowledge of nature to imitate nature was seen by scientists as a more appropriate interest for lower class artisans. A clear-cut distinction between formal and empirical science was made by the pre-Socratic philosopher Parmenides, although his work Peri Physeos is a poem, it may be viewed as an epistemological essay on method in natural science. Parmenides ἐὸν may refer to a system or calculus which can describe nature more precisely than natural languages. Physis may be identical to ἐὸν and he criticized the older type of study of physics as too purely speculative and lacking in self-criticism. He was particularly concerned that some of the early physicists treated nature as if it could be assumed that it had no intelligent order, explaining things merely in terms of motion and matter. The study of things had been the realm of mythology and tradition, however. Aristotle later created a less controversial systematic programme of Socratic philosophy which was teleological and he rejected many of the conclusions of earlier scientists. For example, in his physics, the sun goes around the earth, each thing has a formal cause and final cause and a role in the rational cosmic order. Motion and change is described as the actualization of potentials already in things, while the Socratics insisted that philosophy should be used to consider the practical question of the best way to live for a human being, they did not argue for any other types of applied science

Technology
–
Technology is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, the human species use of technology began with the conversion of natural resources into simple tools. The steady progress of technology has brought weapons of ever-increasing destructive power. It has helped develop more advanced economies and has allowed the rise of a leisure class, many technological processes produce unwanted by-products known as pollution and deplete natural resources to the detriment of Earths environment. Various implementations of technology influence the values of a society and raise new questions of the ethics of technology, examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics. Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the condition or worsens it. The use of the technology has changed significantly over the last 200 years. Before the 20th century, the term was uncommon in English, the term was often connected to technical education, as in the Massachusetts Institute of Technology. The term technology rose to prominence in the 20th century in connection with the Second Industrial Revolution, the terms meanings changed in the early 20th century when American social scientists, beginning with Thorstein Veblen, translated ideas from the German concept of Technik into technology. In German and other European languages, a distinction exists between technik and technologie that is absent in English, which translates both terms as technology. By the 1930s, technology referred not only to the study of the industrial arts, dictionaries and scholars have offered a variety of definitions. Ursula Franklin, in her 1989 Real World of Technology lecture, gave another definition of the concept, it is practice, the way we do things around here. The term is used to imply a specific field of technology, or to refer to high technology or just consumer electronics. Bernard Stiegler, in Technics and Time,1, defines technology in two ways, as the pursuit of life by other than life, and as organized inorganic matter. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems and it is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material, virtual technology, such as software and business methods. W. Brian Arthur defines technology in a broad way as a means to fulfill a human purpose

Pharmaceutical industry
–
The pharmaceutical industry discovers, develops, produces, and markets drugs or pharmaceutical drugs for use as medications. Pharmaceutical companies may deal in generic or brand medications and medical devices and they are subject to a variety of laws and regulations that govern the patenting, testing, safety, efficacy and marketing of drugs. The modern pharmaceutical industry traces its roots to two sources, the first of these were local apothecaries that expanded from their traditional role distributing botanical drugs such as morphine and quinine to wholesale manufacture in the mid 1800s. Multinational corporations including Merck, Hoffman-La Roche, Burroughs-Wellcome, Abbott Laboratories, Eli Lilly, in 1897, John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be efficacious for the acute treatment of asthma attacks. By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion, while highly effective, the requirement for injection limited the use of norepinephrine and orally active derivatives were sought. A structurally similar compound, ephedrine, was identified by Japanese chemists in the Ma Huang plant, following the work of Henry Dale and George Barger at Burroughs-Wellcome, academic chemist Gordon Alles synthesized amphetamine and tested it in asthma patients in 1929. The drug proved to have only modest anti-asthma effects, but produced sensations of exhilaration, amphetamine was developed by Smith, Kline and French as a nasal decongestant under the trade name Benzedrine Inhaler. Amphetamine was eventually developed for the treatment of narcolepsy, post-encepheletic parkinsonism, the discovery was patented and licensed to Bayer pharmaceuticals, which marketed the compound under the trade name Veronal as a sleep aid beginning in 1904. Phenobarbital was among the most widely used drugs for the treatment of epilepsy through the 1970s, today, amphetamine is largely restricted to use in the treatment of attention deficit disorder and phenobarbital in the treatment of epilepsy. A series of experiments performed from the late 1800s to the early 1900s revealed that diabetes is caused by the absence of a substance produced by the pancreas. In 1869, Oskar Minkowski and Joseph von Mering found that diabetes could be induced in dogs by surgical removal of the pancreas. In 1921, Canadian professor Frederick Banting and his student Charles Best repeated this study, the researchers sought assistance from industrial collaborators at Eli Lilly and Co. based on the companys experience with large scale purification of biological materials. Chemist George Walden of Eli Lilly and Company found that careful adjustment of the pH of the extract allowed a relatively pure grade of insulin to be produced, prior to the discovery and widespread availability of insulin therapy the life expectancy of diabetics was only a few months. In 1911 arsphenamine, the first synthetic drug, was developed by Paul Ehrlich. The drug was given the commercial name Salvarsan, arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to time was incurable and led inexorably to severe skin ulceration, neurological damage

Ericsson
–
Ericsson is a multinational networking and telecommunications equipment and services company headquartered in Stockholm, Sweden. Ericsson had 35% market share in the 2G/3G/4G mobile network infrastructure market in 2012, the company was founded in 1876 by Lars Magnus Ericsson, as of 2016 it is headquartered in Stockholm, Sweden. The company employs around 113,000 people and operates in around 180 countries, Ericsson holds over 39,000 granted patents as of May 2015, including many in wireless communications. Lars Magnus Ericsson began his association with telephones in his youth as an instrument maker and he worked for a firm that made telegraph equipment for the Swedish government agency Telegrafverket. In 1876, at the age of 30, he started a repair shop with help from his friend Carl Johan Andersson in central Stockholm. In 1878 Ericsson began making and selling his own telephone equipment and his telephones were not technically innovative. In 1878 he made an agreement to supply telephones and switchboards to Swedens first telecommunications operating company, also in 1878, local telephone importer Numa Peterson hired Ericsson to adjust some telephones from the Bell Telephone Company. He bought a number of Siemens telephones and analyzed the technology and he was familiar with Bell and Siemens Halske telephones through his firms repair work for Telegrafverket and Swedish Railways. He improved these designs to produce a higher-quality instrument to be used by new companies such as Rikstelefon to provide cheaper service than the Bell Group. Ericsson had no patent or royalty problems because Bell had not patented their inventions in Scandinavia and his training as an instrument maker was reflected in the standard of finish and the ornate design of Ericsson telephones of this period. At the end of the year he started to manufacture telephones much like those of Siemens, Ericsson became a major supplier of telephone equipment to Scandinavia. Its factory could not keep up with demand, joinery and metal-plating were contracted out, much of its raw materials were imported, in the following decades Ericsson bought into a number of firms to ensure supplies of brass, wire, ebonite, and magnet steel. Much of the wood used for cabinets was imported from the United States. Stockholms telephone network expanded that year and the company reformed into a telephone manufacturer, when Bell bought the biggest telephone network in Stockholm, it only allowed its own telephones to be used with it. Ericssons equipment was mainly to free telephone associations in the Swedish countryside. The prices of Bell equipment and services led Henrik Tore Cedergren to form an independent telephone company called Stockholms Allmänna Telefonaktiebolag in 1883, as Bell would not deliver equipment to competitors, he formed a pact with Ericsson to supply the equipment for his new telephone network. In 1918 the companies were merged into Allmänna Telefonaktiebolaget LM Ericsson, in 1884, a multiple-switchboard manual telephone exchange was mostly copied from a design by C. E. Scribner at Western Electric. This was legal because the device was not patented in Sweden, a single switchboard could handle up to 10,000 lines

Aeronautics
–
Aeronautics is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of aeronautical Art, Science and Engineering and the profession of Aeronautics. A significant part of science is a branch of dynamics called aerodynamics, which deals with the motion of air. Attempts to fly without any real aeronautical understanding have been made from the earliest times, typically by constructing wings, wiser investigators sought to gain some rational understanding through the study of bird flight. An early example appears in ancient Egyptian texts, later medieval Islamic scientists also made such studies. The founders of modern aeronautics, Leonardo da Vinci in the Renaissance and Cayley in 1799, man-carrying kites are believed to have been used extensively in ancient China. In 1282 the European explorer Marco Polo described the Chinese techniques then current, the Chinese also constructed small hot air balloons, or lanterns, and rotary-wing toys. The lifting medium for his balloon would be an aether whose composition he did not know, although his designs were rational, they were not based on particularly good science. Many of his designs, such as a four-person screw-type helicopter, have severe flaws and he did at least understand that An object offers as much resistance to the air as the air does to the object. His analysis led to the realisation that manpower alone was not sufficient for sustained flight, da Vincis work was lost after his death and did not reappear until it had been overtaken by the work of George Cayley. The modern era of lighter-than-air flight began early in the 17th century with Galileos experiments in which he showed that air has weight and these would be lighter than the displaced air and able to lift an airship. His proposed methods of controlling height are still in use today, by carrying ballast which may be dropped overboard to gain height, in practice de Terzis spheres would have collapsed under air pressure, and further developments had to wait for more practicable lifting gases. From the mid-18th century the Montgolfier brothers in France began experimenting with balloons and their balloons were made of paper, and early experiments using steam as the lifting gas were short-lived due to its effect on the paper as it condensed. Meanwhile, the discovery of hydrogen led Joseph Black in c.1780 to propose its use as a lifting gas, on hearing of the Montgolfier Brothers invitation, the French Academy member Jacques Charles offered a similar demonstration of a hydrogen balloon. Charles and two craftsmen, the Robert brothers, developed a material of rubberised silk for the envelope. The hydrogen gas was to be generated by chemical reaction during the filling process, the Montgolfier designs had several shortcomings, not least the need for dry weather and a tendency for sparks from the fire to set light to the paper balloon. The manned design had a gallery around the base of the rather than the hanging basket of the first, unmanned design. On their free flight, De Rozier and dArlandes took buckets of water, on the other hand, the manned design of Charles was essentially modern

Barack Obama
–
Barack Hussein Obama II is an American politician who served as the 44th President of the United States from 2009 to 2017. He is the first African American to have served as president and he previously served in the U. S. Senate representing Illinois from 2005 to 2008, and in the Illinois State Senate from 1997 to 2004. Obama was born in Honolulu, Hawaii, two years after the territory was admitted to the Union as the 50th state and he grew up mostly in Hawaii, but also spent one year of his childhood in Washington State and four years in Indonesia. After graduating from Columbia University in 1983, he worked as a community organizer in Chicago, in 1988 Obama enrolled in Harvard Law School, where he was the first black president of the Harvard Law Review. After graduation, he became a civil rights attorney and professor, Obama represented the 13th District for three terms in the Illinois Senate from 1997 to 2004, when he ran for the U. S. Senate. In 2008, Obama was nominated for president, a year after his campaign began and he was elected over Republican John McCain, and was inaugurated on January 20,2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate, during his first two years in office, Obama signed more landmark legislation than any Democratic president since LBJs Great Society. Main reforms were the Patient Protection and Affordable Care Act, the Dodd–Frank Wall Street Reform and Consumer Protection Act, after a lengthy debate over the national debt limit, Obama signed the Budget Control and the American Taxpayer Relief Acts. In foreign policy, Obama increased U. S. troop levels in Afghanistan, reduced nuclear weapons with the U. S. -Russian New START treaty, and ended military involvement in the Iraq War. He ordered military involvement in Libya in opposition to Muammar Gaddafi, after winning re-election over Mitt Romney, Obama was sworn in for a second term in 2013. Obama also advocated gun control in response to the Sandy Hook Elementary School shooting, and issued wide-ranging executive actions concerning climate change and immigration. In foreign policy, Obama ordered military intervention in Iraq in response to gains made by ISIL after the 2011 withdrawal from Iraq, Obama left office in January 2017 with a 60% approval rating. He currently resides in Washington, D. C and his presidential library will be built in Chicago. Obama was born on August 4,1961, at Kapiʻolani Maternity & Gynecological Hospital in Honolulu and he is the only President to have been born in Hawaii. He was born to a mother and a black father. His mother, Ann Dunham, was born in Wichita, Kansas, of mostly English descent, with some German, Irish, Scottish, Swiss and his father, Barack Obama Sr. was a married Luo Kenyan man from Nyangoma Kogelo. Obamas parents met in 1960 in a Russian language class at the University of Hawaii at Manoa, the couple married in Wailuku, Hawaii on February 2,1961, six months before Obama was born. In late August 1961, Obamas mother moved him to the University of Washington in Seattle for a year

Statistics
–
Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data. In applying statistics to, e. g. a scientific, industrial, or social problem, populations can be diverse topics such as all people living in a country or every atom composing a crystal. Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys, statistician Sir Arthur Lyon Bowley defines statistics as Numerical statements of facts in any department of inquiry placed in relation to each other. When census data cannot be collected, statisticians collect data by developing specific experiment designs, representative sampling assures that inferences and conclusions can safely extend from the sample to the population as a whole. In contrast, an observational study does not involve experimental manipulation, inferences on mathematical statistics are made under the framework of probability theory, which deals with the analysis of random phenomena. A standard statistical procedure involves the test of the relationship between two data sets, or a data set and a synthetic data drawn from idealized model. A hypothesis is proposed for the relationship between the two data sets, and this is compared as an alternative to an idealized null hypothesis of no relationship between two data sets. Rejecting or disproving the hypothesis is done using statistical tests that quantify the sense in which the null can be proven false. Working from a hypothesis, two basic forms of error are recognized, Type I errors and Type II errors. Multiple problems have come to be associated with this framework, ranging from obtaining a sufficient sample size to specifying an adequate null hypothesis, measurement processes that generate statistical data are also subject to error. Many of these errors are classified as random or systematic, the presence of missing data or censoring may result in biased estimates and specific techniques have been developed to address these problems. Statistics continues to be an area of research, for example on the problem of how to analyze Big data. Statistics is a body of science that pertains to the collection, analysis, interpretation or explanation. Some consider statistics to be a mathematical science rather than a branch of mathematics. While many scientific investigations make use of data, statistics is concerned with the use of data in the context of uncertainty, mathematical techniques used for this include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure-theoretic probability theory. In applying statistics to a problem, it is practice to start with a population or process to be studied. Populations can be diverse topics such as all living in a country or every atom composing a crystal. Ideally, statisticians compile data about the entire population and this may be organized by governmental statistical institutes
