Inventor
–
An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process and it may be an improvement upon a machine or product or a new process for creating an object or a result. An invention that achieves a unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field, an inventor may be taking a big step in success or failure. A patent legally protects the property rights of the inventor. The rules and requirements for patenting an invention vary from country to country, another meaning of invention is cultural invention, which is an innovative set of useful social behaviours adopted by people and passed on to others. The Institute for Social Inventions collected many such ideas in magazines, Invention is also an important component of artistic and design creativity. Inventions often extend the boundaries of knowledge, experience or capability. Brainstorming also can spark new ideas for an invention, collaborative creative processes are frequently used by engineers, designers, architects and scientists. Co-inventors are frequently named on patents, in addition, many inventors keep records of their working process - notebooks, photos, etc. including Leonardo da Vinci, Galileo Galilei, Evangelista Torricelli, Thomas Jefferson and Albert Einstein. In the process of developing an invention, the idea may change. The invention may become simpler, more practical, it may expand, working on one invention can lead to others too. History shows that turning the concept of an invention into a device is not always swift or direct. Inventions may also more useful after time passes and other changes occur. For example, the became more useful once powered flight was a reality. Invention is often a creative process, an open and curious mind allows an inventor to see beyond what is known. Seeing a new possibility, connection, or relationship can spark an invention, inventive thinking frequently involves combining concepts or elements from different realms that would not normally be put together. Sometimes inventors disregard the boundaries between distinctly separate territories or fields, several concepts may be considered when thinking about invention

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

Bread
–
Bread is a staple food prepared from a dough of flour and water, usually by baking. Throughout recorded history it has been popular around the world and is one of the oldest artificial foods, proportions of types of flour and other ingredients vary widely, as do modes of preparation. As a result, types, shapes, sizes, and textures of breads differ around the world, Bread may be leavened by processes such as reliance on naturally occurring sourdough microbes, chemicals, industrially produced yeast, or high-pressure aeration. Some bread is cooked before it can leaven, including for traditional or religious reasons, non-cereal ingredients such as fruits, nuts and fats may be included. Commercial bread commonly contains additives to improve flavor, texture, color, shelf life, Bread is served in various forms with any meal of the day. It is eaten as a snack, and used as an ingredient in other preparations, such as sandwiches. It forms the main component of bread pudding, as well as of stuffings designed to fill cavities or retain juices that otherwise might drip out. Bread has a social and emotional significance beyond its importance as nourishment and it plays essential roles in religious rituals and secular culture. Its prominence in daily life is reflected in language, where it appears in proverbs, colloquial expressions, in prayer and in the etymology of words, the Old English word for bread was hlaf, which appears to be the oldest Teutonic name. Old High German hleib and modern German Laib derive from this Proto-Germanic word, Bread is one of the oldest prepared foods. Evidence from 30,000 years ago in Europe revealed starch residue on rocks used for pounding plants. It is possible that during this time, starch extract from the roots of plants, such as cattails and ferns, was spread on a rock, placed over a fire. Around 10,000 BC, with the dawn of the Neolithic age, yeast spores are ubiquitous, including on the surface of cereal grains, so any dough left to rest leavens naturally. There were multiple sources of leavening available for early bread, airborne yeasts could be harnessed by leaving uncooked dough exposed to air for some time before cooking. Pliny the Elder reported that the Gauls and Iberians used the foam skimmed from beer to produce a kind of bread than other peoples. Parts of the ancient world that drank wine instead of used a paste composed of grape juice and flour that was allowed to begin fermenting, or wheat bran steeped in wine. The most common source of leavening was to retain a piece of dough from the day to use as a form of sourdough starter. In 1961 the Chorleywood bread process was developed, which used the intense mechanical working of dough to dramatically reduce the fermentation period, the process, whose high-energy mixing allows for the use of lower protein grain, is now widely used around the world in large factories

Sliced bread
–
Sliced bread is a loaf of bread that has been sliced with a machine and packaged for convenience. It was first sold in 1928, advertised as the greatest forward step in the industry since bread was wrapped. This led to the popular phrase greatest thing since sliced bread, otto Frederick Rohwedder of Davenport, Iowa, United States, invented the first loaf-at-a-time bread-slicing machine. A prototype he built in 1912 was destroyed in a fire, the first commercial use of the machine was by the Chillicothe Baking Company of Chillicothe, Missouri, which produced their first slices on July 7,1928. Their product, Kleen Maid Sliced Bread, proved a success, Battle Creek, Michigan, has a competing claim as the first city to sell bread sliced by Rohwedders machine, however, historians have produced no documentation backing up Battle Creeks claim. The bread was advertised as the greatest forward step in the industry since bread was wrapped. St. Louis baker Gustav Papendick bought Rohwedders second bread slicer, after failures trying rubber bands and metal pins, he settled on placing the slices into a cardboard tray. The tray aligned the slices, allowing mechanized wrapping machines to function, long, who promoted the Holsum Bread brand, used by various independent bakers around the country, pioneered and promoted the packaging of sliced bread beginning in 1928. In 1930 Wonder Bread, first sold in 1925, started marketing sliced bread nationwide and this increased consumption of bread and, in turn, increased consumption of spreads, such as jam, to put on the bread. During 1943, U. S. officials imposed a ban on sliced bread as a wartime conservation measure. The ban was ordered by Claude R. Wickard who held the position of Food Administrator, according to the New York Times, officials explained that the ready-sliced loaf must have a heavier wrapping than an unsliced one if it is not to dry out. It was also intended to counteract a rise in the price of bread and my husband and four children are all in a rush during and after breakfast. Without ready-sliced bread I must do the slicing for toast—two pieces for each one—thats ten, for their lunches I must cut by hand at least twenty slices, for two sandwiches apiece. Afterward I make my own toast, twenty-two slices of bread to be cut in a hurry. On January 26, however, John F. we are prepared to take measures if necessary. On March 8,1943, the ban was rescinded, in Japan, the same half-loaf of bread is labeled by the number of slices. Thin sliced crustless sandwich bread is sold in Japan, since regular 4–6 slice bread is deemed too thick. In Canada and the United States, Texas toast is a type of packaged bread which is sliced at double the thickness of most sliced breads

Machine
–
A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by chemical, thermal, or electrical means, historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines, a simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist. Examples include vehicles, electronic systems, molecular machines, computers, television, the word machine derives from the Latin word machina, which in turn derives from the Greek. The word mechanical comes from the same Greek roots, however, the Ancient Greeks probably have borrowed the word mekhane from the ancient Hebrews. The ancient Greeks were familiar with the Hebrew Scriptures and language, a wider meaning of fabric, structure is found in classical Latin, but not in Greek usage. This meaning is found in late medieval French, and is adopted from the French into English in the mid-16th century, in the 17th century, the word could also mean a scheme or plot, a meaning now expressed by the derived machination. The modern meaning develops out of specialized application of the term to stage engines used in theater and to siege engines. Simple Machines are commonly reckoned to be Six in Number, viz. the Ballance, Leaver, Pulley, Wheel, Wedge, compound Machines, or Engines, are innumerable. The word engine used as a synonym both by Harris and in later language derives ultimately from Latin ingenium ingenuity, an invention, perhaps the first example of a human made device designed to manage power is the hand axe, made by chipping flint to form a wedge. A wedge is a machine that transforms lateral force and movement of the tool into a transverse splitting force. The idea of a simple machine originated with the Greek philosopher Archimedes around the 3rd century BC, who studied the Archimedean simple machines, lever, pulley and he discovered the principle of mechanical advantage in the lever. Later Greek philosophers defined the five simple machines and were able to roughly calculate their mechanical advantage. Heron of Alexandria in his work Mechanics lists five mechanisms that can set a load in motion, lever, windlass, pulley, wedge, and screw, however the Greeks understanding was limited to statics and did not include dynamics or the concept of work. In 1586 Flemish engineer Simon Stevin derived the mechanical advantage of the inclined plane, the complete dynamic theory of simple machines was worked out by Italian scientist Galileo Galilei in 1600 in Le Meccaniche. He was the first to understand that simple machines do not create energy, the classic rules of sliding friction in machines were discovered by Leonardo da Vinci, but remained unpublished in his notebooks. They were rediscovered by Guillaume Amontons and were developed by Charles-Augustin de Coulomb. The word mechanical refers to the work that has produced by machines or the machinery

Commerce
–
Commerce is the activity of buying and selling of goods and services, especially on a large scale. The system includes legal, economic, political, social, cultural and technological systems that are in operation in any country or internationally, commerce is derived from the Latin commercium, from cum, together, and merx, merchandise. Some commentators trace the origins of commerce to the start of transaction in prehistoric times. Apart from traditional self-sufficiency, trading became a facility of prehistoric people. Historian Peter Watson and Ramesh Manickam dates the history of commerce from circa 150,000 years ago. In historic times, the introduction of currency as a money, facilitated a wider exchange of goods. Numismatists have collections of these tokens, which include coins from some Ancient World large-scale societies. For example, if a man who makes pots for a living needs a new house, he/she may wish to hire someone to build it for him/her. But he/she cannot make an equivalent number of pots to equal this service done for him/her, because if the builder could build the house. During the Middle Ages, commerce developed in Europe by trading luxury goods at trade fairs, wealth became converted into movable wealth or capital. Banking systems developed where money on account was transferred across national boundaries, hand to hand markets became a feature of town life, and were regulated by town authorities. Today commerce includes as a subset a complex system of companies which try to maximize their profits by offering products and services to the market at the lowest production cost

Davenport, Iowa
–
Davenport was founded on May 14,1836 by Antoine Le Claire and was named for his friend, George Davenport, a colonel during the Black Hawk War stationed at nearby Fort Armstrong. According to the 2010 census, the city had a population of 99,685, located approximately halfway between Chicago and Des Moines, Davenport is on the border of Iowa and Illinois. The city is prone to frequent flooding due to its location on the Mississippi River, there are two main universities, Saint Ambrose University and Palmer College of Chiropractic, which is where the first chiropractic adjustment took place. Several annual music festivals take place in Davenport, including the Mississippi Valley Blues Festival, The Mississippi Valley Fair, an internationally known 7-mile foot race called the Bix 7 is run during the festival. The city has a Class A minor league team, the Quad Cities River Bandits. Davenport has 50 plus parks and facilities, as well as over 20 miles of paths for biking or walking. Four interstates and two major United States Highways serve the city, Davenport has seen steady population growth since its incorporation, with an exception being the 1980s, when the population decreased due to job loss. The Quad Cities was ranked as the most affordable metropolitan area in 2010 by Forbes, in 2007, Davenport, along with neighboring Rock Island, won the City Livability Award in the small-city category from the U. S. In 2012, Davenport as well as the Quad Cities Metropolitan Area was ranked among the areas in the nation in the growth of high-tech jobs. The current mayor of Davenport is Frank Klipsch, the land was originally owned by the Sauk people, Meskwaki, and Ho-Chunk – indigenous peoples of the Americas. In 1803 France sold it to the United States under the Louisiana Purchase, lieutenant Zebulon Pike was the first United States representative to officially visit the Upper Mississippi River area. On August 27,1805, Pike camped on the present day site of Davenport, in 1832, a group of Sauk, Meskwaki, and Kickapoo people were defeated by the United States in the Black Hawk War. The United States government then concluded the Black Hawk Purchase, sometimes called the Forty-Mile Strip or Scotts Purchase, the purchase was made for $640,000 on September 21,1832 and contained an area of some 6 million acres, at a price equivalent to 11 cents/acre. Although named after the defeated chief Black Hawk, he was being held prisoner at the time, the purchase was therefore agreed to by Sauk chief Keokuk, who had remained neutral in the war. It was made on the site of present-day Davenport, army General Winfield Scott and Governor of Illinois, John Reynolds, acted on behalf of the United States, with the future Davenport founder, half-Native, Antoine Le Claire serving as translator. Chief Keokuk gave a portion of land to Antoine Le Claires wife, Marguerite. Antoine built their home on the spot where the agreement was signed. Antoine did so, finishing the Treaty House in the spring of 1833, Davenport was established on May 14,1836 by Le Claire, and named after his friend Colonel George Davenport, who was stationed at Fort Armstrong during the war

Ethnic group
–
An ethnic group or ethnicity is a category of people who identify with each other based on similarities, such as common ancestral, language, social, cultural or national experiences. Unlike other social groups, ethnicity is often an inherited status based on the society in which one lives, in some cases, it can be adopted if a person moves into another society. Ethnic groups, derived from the historical founder population, often continue to speak related languages. By way of language shift, acculturation, adoption and religious conversion, it is possible for individuals or groups to leave one ethnic group. Ethnicity is often used synonymously with terms such as nation or people. In English, it can also have the connotation of something exotic, generally related to cultures of more recent immigrants, the largest ethnic groups in modern times comprise hundreds of millions of individuals, while the smallest are limited to a few dozen individuals. Conversely, formerly separate ethnicities can merge to form a pan-ethnicity, whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis. The term ethnic is derived from the Greek word ἔθνος ethnos, the inherited English language term for this concept is folk, used alongside the latinate people since the late Middle English period. In Early Modern English and until the mid-19th century, ethnic was used to mean heathen or pagan, as the Septuagint used ta ethne to translate the Hebrew goyim the nations, non-Hebrews, non-Jews. The Greek term in antiquity could refer to any large group, a host of men. In the 19th century, the term came to be used in the sense of peculiar to a race, people or nation, the abstract ethnicity had been used for paganism in the 18th century, but now came to express the meaning of an ethnic character. The term ethnic group was first recorded in 1935 and entered the Oxford English Dictionary in 1972, depending on the context that is used, the term nationality may either be used synonymously with ethnicity, or synonymously with citizenship. The process that results in the emergence of an ethnicity is called ethnogenesis, the Greeks at this time did not describe foreign nations but had also developed a concept of their own ethnicity, which they grouped under the name of Hellenes. Herodotus gave an account of what defined Greek ethnic identity in his day, enumerating shared descent. Whether ethnicity qualifies as a universal is to some extent dependent on the exact definition used. Many social scientists, such as anthropologists Fredrik Barth and Eric Wolf and they regard ethnicity as a product of specific kinds of inter-group interactions, rather than an essential quality inherent to human groups. According to Thomas Hylland Eriksen, the study of ethnicity was dominated by two distinct debates until recently, one is between primordialism and instrumentalism. In the primordialist view, the participant perceives ethnic ties collectively, as a given, even coercive

Germans
–
Germans are a Germanic ethnic group native to Central Europe, who share a common German ancestry, culture and history. German is the mother tongue of a substantial majority of ethnic Germans. The English term Germans has historically referred to the German-speaking population of the Holy Roman Empire since the Late Middle Ages, before the collapse of communism and the reunification of Germany in 1990, Germans constituted the largest divided nation in Europe by far. Ever since the outbreak of the Protestant Reformation within the Holy Roman Empire, of approximately 100 million native speakers of German in the world, roughly 80 million consider themselves Germans. Thus, the number of Germans lies somewhere between 100 and more than 150 million, depending on the criteria applied. Today, people from countries with German-speaking majorities most often subscribe to their own national identities, the German term Deutsche originates from the Old High German word diutisc, referring to the Germanic language of the people. It is not clear how commonly, if at all, the word was used as an ethnonym in Old High German, used as a noun, ein diutscher in the sense of a German emerges in Middle High German, attested from the second half of the 12th century. The Old French term alemans is taken from the name of the Alamanni and it was loaned into Middle English as almains in the early 14th century. The word Dutch is attested in English from the 14th century, denoting continental West Germanic dialects, while in most Romance languages the Germans have been named from the Alamanni, the Old Norse, Finnish and Estonian names for the Germans were taken from that of the Saxons. In Slavic languages, the Germans were given the name of němьci, originally with a meaning foreigner, the English term Germans is only attested from the mid-16th century, based on the classical Latin term Germani used by Julius Caesar and later Tacitus. It gradually replaced Dutch and Almains, the latter becoming mostly obsolete by the early 18th century, the Germans are a Germanic people, who as an ethnicity emerged during the Middle Ages. Originally part of the Holy Roman Empire, around 300 independent German states emerged during its decline after the Peace of Westphalia in 1648 ending the Thirty Years War and these states eventually formed into modern Germany in the 19th century. The concept of a German ethnicity is linked to Germanic tribes of antiquity in central Europe, the early Germans originated on the North German Plain as well as southern Scandinavia. By the 2nd century BC, the number of Germans was significantly increasing and they began expanding into eastern Europe, during antiquity these Germanic tribes remained separate from each other and did not have writing systems at that time. In the European Iron Age the area that is now Germany was divided into the La Tène horizon in Southern Germany and the Jastorf culture in Northern Germany. By 55 BC, the Germans had reached the Danube river and had either assimilated or otherwise driven out the Celts who had lived there, and had spread west into what is now Belgium and France. Conflict between the Germanic tribes and the forces of Rome under Julius Caesar forced major Germanic tribes to retreat to the east bank of the Rhine, in Roman-held territories with Germanic populations, the Germanic and Roman peoples intermarried, and Roman, Germanic, and Christian traditions intermingled. The adoption of Christianity would later become an influence in the development of a common German identity

Sibling
–
A sibling is one of two or more individuals having one or both parents in common. A male sibling is a brother, and a sibling is a sister. In most societies throughout the world, siblings often grow up together, the emotional bond between siblings is often complicated and is influenced by factors such as parental treatment, birth order, personality, and personal experiences outside the family. However, there are cases where siblings grow up in separate homes and it is known that both nature and nurture figure in development, researchers are attempting to ascertain just which one plays the larger role. Identical twins share 100% of their DNA, full siblings are first-degree relatives and, on average, share 50% of their genes out of those that vary among humans. Half-siblings are second-degree relatives and have, on average, a 25% overlap in their genetic variation. Full siblings have the same parents and are 50% related. Identical twins by definition are 100% related, there are two types of twins, identical and fraternal. Identical twins have exactly the same genes, fraternal twins are no more similar than regular siblings, often, twins with a close relationship will develop a twin language from infanthood, a language only shared and understood between the two. Studies suggest that identical twins appear to display more twin talk than fraternal twins, at about 3 years of age, twin talk usually ends. Researchers were interested in subjects who were in the years of life. They knew that past studies suggested that genetics played a role in ones personality in the earlier years of their life. However, they were curious about whether or not this was later on in life. They gathered subjects with an age of 59, who included 99 pairs of identical twins. They also gathered twins who were reared together,160 pairs of identical twins and they studied the most heritable traits in regard to personality, which are emotionality, activity level and sociability, also known as EAS. This study found that identical twins resembled each other twice as much as fraternal twins, furthermore, environment influences personality substantially, however, it has little to do with whether they are reared together or apart. This study also suggests that heritability is substantial, but not as substantial as for younger subjects, half-siblings are people who share one parent but not both. They may share the same mother but different fathers, or they may have the same father and they share only one parent instead of two as full siblings do and are on average 25% related
