An expert is somebody who has a broad and deep competence in terms of knowledge, skill and experience through practice and education in a particular field. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion on that topic. Historically, an expert was referred to as a sage. The individual was usually a profound thinker distinguished for wisdom and sound judgment. In specific fields, the definition of expert is well established by consensus and therefore it is not always necessary for individuals to have a professional or academic qualification for them to be accepted as an expert. In this respect, a shepherd with 50 years of experience tending flocks would be widely recognized as having complete expertise in the use and training of sheep dogs and the care of sheep. Another example from computer science is that an expert system may be taught by a human and thereafter considered an expert, often outperforming human beings at particular tasks. In law, an expert witness must be recognized by argument and authority. Research in this area attempts to understand the relation between expert knowledge, skills and personal characteristics and exceptional performance. Some researchers have investigated the cognitive structures and processes of experts. The fundamental aim of this research is to describe what it is that experts know and how they use their knowledge to achieve performance that most people assume requires extreme or extraordinary ability. Studies have investigated the factors that enable experts to be fast and accurate.Reaction may refer to a process or to a response to an action, event, or exposure:Bulletproofing is the process of making something capable of stopping a bullet or similar high velocity projectiles e.g. shrapnel. The term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location, or simply sufficient kinetic (movement) energy to overcome it. Clothing (also known as clothes, apparel, and attire) are items worn on the body. Typically, clothing is made of fabrics or textiles, but over time it has included garments made from animal skin and other thin sheets of materials and natural products found in the environment, put together. The wearing of clothing is mostly restricted to human beings and is a feature of all human societies. The amount and type of clothing worn depends on gender, body type, social factors, and geographic considerations. Garments cover the body, footwear covers the feet, gloves cover the hands, while hats and headgear cover the head. Eyewear and jewelry are not generally considered items of clothing, but play an important role in fashion and clothing as costume. Other wearables are not always considered to be clothing despite belonging to an accepted class, such as orthodontic headgear, which is a medical appliance. The human body is not always complete, and sometimes includes prosthetic devices, such as a limb prosthesis, which might be adorned similarly to an intact body, differently, or not at all. Some styles of prosthetic legs are designed to require ordinary street shoes to function properly. Clothing serves many purposes: it can serve as protection from the elements, rough surfaces, sharp stones, rash-causing plants, insect bites, splinters, thorns and prickles by providing a barrier between the skin and the environment. Clothing can insulate against cold or hot conditions, and it can provide a hygienic barrier, keeping infectious and toxic materials away from the body. It can protect feet from injury and discomfort or facilitate navigation in varied environments. Clothing also provides protection from ultraviolet radiation. It may used to prevent glare or increase visual accuity in harsh environments, such as brimmed hats. Clothing is used for protection against injury in specific tasks and occupations, sports, and warfare. Fashioned with pockets, belts, or loops, clothing may provide a means to carry things while freeing the hands. Clothing has significant social factors as well. Wearing clothes is a variable social norm. It may connote modesty. Being deprived of clothing in front of others may be embarrassing. In many parts of the world, not wearing clothes in public so that genitals, breasts, or buttocks are visible could be considered indecent exposure. Pubic area or genital coverage is the most frequently encountered minimum found cross-culturally and regardless of climate, implying social convention as the basis of customs. Clothing also may be used to communicate social status, wealth, group identity, and individualism. Some forms of personal protective equipment amount to clothing, such as coveralls, chaps or a doctor's white coat, with similar requirements for maintenance and cleaning as other textiles (boxing gloves function both as protective equipment and as a sparring weapon, so the equipment aspect rises above the glove aspect). More specialized forms of protective equipment, such as face shields are classified protective accessories. At the far extreme, self-enclosing diving suits or space suits are form fitting body covers, and amount to a form of dress, without being clothing per se, while containing enough high technology to amount to more of a tool than a garment. This line will continue to blur as wearable technology embeds assistive devices directly into the fabric itself; the enabling innovations are ultra low power consumption and flexible electronic substrates. Clothing also hybridizes into a personal transportation system (ice skates, roller skates, cargo pants, other outdoor survival gear, one-man band) or concealment system (stage magicians, hidden linings or pockets in tradecraft, integrated holsters for concealed carry, merchandise-laden trench coats on the black market — where the purpose of the clothing often carries over into disguise). A mode of dress fit to purpose, whether stylistic or functional, is known as an outfit or ensemble.The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, 326 Indian reservations, and some minor possessions. At 3.8 million square miles (9.8 million square kilometers), it is the world's third- or fourth-largest country by total area. The United States shares significant land borders with Canada to the north and Mexico to the south, as well as limited maritime borders with the Bahamas, Cuba, and Russia. With a population of more than 331 million people, it is the third most populous country in the world. The national capital is Washington, D.C., and the most populous city is New York City. Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago, and European colonization began in the 16th century. The United States emerged from the thirteen British colonies established along the East Coast. Disputes over taxation and political representation with Great Britain led to the American Revolutionary War (1775–1783), which established independence. In the late 18th century, the U.S. began expanding across North America, gradually obtaining new territories, sometimes through war, frequently displacing Native Americans, and admitting new states; by 1848, the United States spanned the continent. Slavery was legal in the southern United States until the second half of the 19th century when the American Civil War led to its abolition. The Spanish–American War and World War I established the U.S. as a world power, a status confirmed by the outcome of World War II. During the Cold War, the United States fought the Korean War and the Vietnam War but avoided direct military conflict with the Soviet Union. The two superpowers competed in the Space Race, culminating in the 1969 spaceflight that first landed humans on the Moon. The Soviet Union's dissolution in 1991 ended the Cold War, leaving the United States as the world's sole superpower. The United States is a federal republic and a representative democracy with three separate branches of government, including a bicameral legislature. It is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, NATO, and other international organizations. It is a permanent member of the United Nations Security Council. Considered a melting pot of cultures and ethnicities, its population has been profoundly shaped by centuries of immigration. The U.S. ranks high in international measures of economic freedom, quality of life, education, and human rights, and has low levels of perceived corruption. However, the country has received criticism concerning inequality related to race, wealth and income, the use of capital punishment, high incarceration rates, and lack of universal health care. The United States is a highly developed country, accounts for approximately a quarter of global GDP, and is the world's largest economy by GDP at market exchange rates. By value, the United States is the world's largest importer and the second-largest exporter of goods. Although its population is only 4.2% of the world's total, it holds 29.4% of the total wealth in the world, the largest share held by any country. Making up more than a third of global military spending, it is the foremost military power in the world; and it is a leading political, cultural, and scientific force internationally.Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare is to bring two or more things together (physically or in contemplation) and to examine them systematically, identifying similarities and differences among them. Comparison has a different meaning within each framework of study. Any exploration of the similarities or differences of two or more units is a comparison. In the most limited sense, it consists of comparing two units isolated from each other. To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts.A nation is a community of people formed on the basis of a combination of shared features such as language, history, ethnicity, culture and/or territory. A nation is thus the collective identity of a group of people understood as defined by those features. A nation is generally more overtly political than an ethnic group; it has been described as "a fully mobilized or institutionalized ethnic group". Some nations are equated with ethnic groups (see ethnic nationalism and nation state) and some are equated with an affiliation with a social and political constitution [citizenship (see civic nationalism and multiculturalism)], also some of them don't change its definition and keep it as culture (see cultural nationalism). A nation has also been defined as a cultural-political community that has become conscious of its autonomy, unity and particular interests.Benedict Anderson characterised a nation as an "imagined community", and Paul James sees it as an "abstract community". A nation is an imagined community in the sense that the material conditions exist for imagining extended and shared connections and that it is objectively impersonal, even if each individual in the nation experiences themselves as subjectively part of an embodied unity with others. For the most part, members of a nation remain strangers to each other and will likely never meet. Hence the phrase, "a nation of strangers" used by such writers as American journalist Vance Packard.
