Aarhus
–
Aarhus is the second-largest city in Denmark and the seat of Aarhus municipality. It is located on the east coast of the Jutland peninsula, in the centre of Denmark,187 kilometres northwest of Copenhagen and 289 kilometres north of Hamburg. The inner urban area contains 264,716 inhabitants and the population is 330,639. Aarhus is the city in the East Jutland metropolitan area. The history of Aarhus began as a fortified Viking settlement founded in the 8th century, the city was founded on the northern shores of a fjord at a natural harbour and the primary driver of growth was for centuries seaborne trade in agricultural products. Market town privileges were granted in 1441, but growth stagnated in the 17th century as the city suffered blockades, in the 19th century it was occupied twice by German troops during the Schleswig Wars but avoided destruction. As the industrial revolution took hold, the city grew to become the second-largest in the country by the 20th century, today Aarhus is at the cultural and economic core of the region and the largest centre for trade, services and industry in Jutland. The city ranks as the 92nd largest city in the European Union and it is also a top 100 conference city in the world. Aarhus is the industrial port of the country in terms of container handling. Major Danish companies have based their headquarters here and people commute for work and it is a centre for research and education in the Nordic countries and home to Aarhus University, Scandinavias largest university, including Aarhus University Hospital and INCUBA Science Park. Aarhus is notable for its musical history, in the 1950s many jazz clubs sprang up around the city, fuelled by the young population. By the 1960s, the music scene diversified into rock and other genres, in the 1970s and 1980s, Aarhus became the centre for Denmarks rock music fostering many iconic bands such as TV-2 and Gnags. Aarhus is home to the annual eight-day Aarhus International Jazz Festival, the SPoT Festival, in 2017 Aarhus are European Capital of Culture. In Valdemars Census Book the city was called Arus, and in Icelandic it was known as Aros and it is a compound of the two words ār, genitive of ā, and ōss. The name originates from the location around the mouth of Aarhus Å. The spelling Aarhus is first found in 1406 and gradually became the norm in the 17th century, aarhus/Århus spelling With the Danish spelling reform of 1948, Aa was changed to Å. Some Danish cities resisted the new spelling of their names, notably Aalborg, Århus city council explicitly embraced the new spelling, as it was thought to enhance an image of progressiveness. In 2010, the city voted to change the name from Århus to Aarhus in order to strengthen the international profile of the city

Copenhagen
–
Copenhagen, Danish, København, Latin, Hafnia) is the capital and most populous city of Denmark. Copenhagen has an population of 1,280,371. The Copenhagen metropolitan area has just over 2 million inhabitants, the city is situated on the eastern coast of the island of Zealand, another small portion of the city is located on Amager, and is separated from Malmö, Sweden, by the strait of Øresund. The Øresund Bridge connects the two cities by rail and road, originally a Viking fishing village founded in the 10th century, Copenhagen became the capital of Denmark in the early 15th century. Beginning in the 17th century it consolidated its position as a centre of power with its institutions, defences. After suffering from the effects of plague and fire in the 18th century and this included construction of the prestigious district of Frederiksstaden and founding of such cultural institutions as the Royal Theatre and the Royal Academy of Fine Arts. Later, following the Second World War, the Finger Plan fostered the development of housing, since the turn of the 21st century, Copenhagen has seen strong urban and cultural development, facilitated by investment in its institutions and infrastructure. The city is the cultural, economic and governmental centre of Denmark, Copenhagens economy has seen rapid developments in the service sector, especially through initiatives in information technology, pharmaceuticals and clean technology. Since the completion of the Øresund Bridge, Copenhagen has become integrated with the Swedish province of Scania and its largest city, Malmö. With a number of connecting the various districts, the cityscape is characterized by parks, promenades. Copenhagen is home to the University of Copenhagen, the Technical University of Denmark, the University of Copenhagen, founded in 1479, is the oldest university in Denmark. Copenhagen is home to the FC København and Brøndby football clubs, the annual Copenhagen Marathon was established in 1980. Copenhagen is one of the most bicycle-friendly cities in the world, the Copenhagen Metro serves central Copenhagen while the Copenhagen S-train network connects central Copenhagen to its outlying boroughs. Serving roughly 2 million passengers a month, Copenhagen Airport, Kastrup, is the largest airport in the Nordic countries, the name of the city reflects its origin as a harbour and a place of commerce. The original designation, from which the contemporary Danish name derives, was Køpmannæhafn, meaning merchants harbour, the literal English translation would be Chapmans haven. The English name for the city was adapted from its Low German name, the abbreviations Kbh. or Kbhvn are often used in Danish for København, and kbh. for københavnsk. The chemical element hafnium is named for Copenhagen, where it was discovered, the bacterium Hafnia is also named after Copenhagen, Vagn Møller of the State Serum Institute in Copenhagen named it in 1954. Excavations in Pilestræde have also led to the discovery of a well from the late 12th century, the remains of an ancient church, with graves dating to the 11th century, have been unearthed near where Strøget meets Rådhuspladsen

Physician
–
Both the role of the physician and the meaning of the word itself vary around the world. Degrees and other qualifications vary widely, but there are common elements, such as medical ethics requiring that physicians show consideration, compassion. Around the world the term refers to a specialist in internal medicine or one of its many sub-specialties. This meaning of physician conveys a sense of expertise in treatment by drugs or medications and this term is at least nine hundred years old in English, physicians and surgeons were once members of separate professions, and traditionally were rivals. Henry VIII granted a charter to the London Royal College of Physicians in 1518 and it was not until 1540 that he granted the Company of Barber/Surgeons its separate charter. In the same year, the English monarch established the Regius Professorship of Physic at the University of Cambridge, newer universities would probably describe such an academic as a professor of internal medicine. Hence, in the 16th century, physic meant roughly what internal medicine does now, currently, a specialist physician in the United States may be described as an internist. Another term, hospitalist, was introduced in 1996, to describe US specialists in internal medicine who work largely or exclusively in hospitals, such hospitalists now make up about 19% of all US general internists, who are often called general physicians in Commonwealth countries. In such places, the more general English terms doctor or medical practitioner are prevalent, in Commonwealth countries, specialist pediatricians and geriatricians are also described as specialist physicians who have sub-specialized by age of patient rather than by organ system. Around the world, the term physician and surgeon is used to describe either a general practitioner or any medical practitioner irrespective of specialty. This usage still shows the meaning of physician and preserves the old difference between a physician, as a practitioner of physic, and a surgeon. The term may be used by state medical boards in the United States of America, in modern English, the term physician is used in two main ways, with relatively broad and narrow meanings respectively. This is the result of history and is often confusing and these meanings and variations are explained below. In the United States and Canada, the term physician describes all medical practitioners holding a professional medical degree, the American Medical Association, established in 1847, as well as the American Osteopathic Association, founded in 1897, both currently use the term physician to describe members. However, the American College of Physicians, established in 1915, does not, its title uses physician in its original sense. A physician trained in the United States has either a Doctor of Medicine degree, all boards of certification now require that physicians demonstrate, by examination, continuing mastery of the core knowledge and skills for a chosen specialty. Recertification varies by particular specialty between every seven and every ten years, graduates of osteopathic medical schools in the United States should not be confused with osteopaths, who are trained in the European and Commonwealth nations. Their training is similar to physical therapy and they are not licensed to prescribe medications or perform surgeries, also in the United States, the American Podiatric Medical Association defines podiatrists as physicians and surgeons that fall under the department of surgery in hospitals

Natural history
–
Natural history is the research and study of organisms including animals, fungi and plants in their environment, leaning more towards observational than experimental methods of study. It encompasses scientific research but is not limited to it, with articles nowadays more often published in magazines than in academic journals. Grouped among the sciences, natural history is the systematic study of any category of natural objects or organisms. That is a broad designation in a world filled with many narrowly focused disciplines. For example, geobiology has a strong multi-disciplinary nature combining scientists, a person who studies natural history is known as a naturalist or natural historian. The English term natural history is a translation of the Latin historia naturalis and its meaning has narrowed progressively with time, while the meaning of the related term nature has widened. In antiquity, it covered essentially anything connected with nature or which used materials drawn from nature. For example, Pliny the Elders encyclopedia of this title, published circa 77 to 79 AD, covers astronomy, geography, man and his technology, medicine and superstition as well as animals and plants. Medieval European academics considered knowledge to have two divisions, the humanities and divinity, with science studied largely through texts rather than observation or experiment. In modern terms, natural philosophy roughly corresponded to modern physics and chemistry, natural history had been encouraged by practical motives, such as Linnaeus aspiration to improve the economic condition of Sweden. Similarly, the Industrial Revolution prompted the development of geology to help find useful mineral deposits, the astronomer, William Herschel was also a natural historian. Instead of working with plants or minerals he worked with the stars and he spent his time building telescopes to see the stars and the rest of the time watching the stars. In the beginning, he believed there to be a known as a nebulae. Herschel can be considered a natural historian because he observed the natural world, in the process he made charts of all the stars and kept records of all that he saw. S. Wilcove and T. Eisner, The close observation of organisms—their origins, their evolution, their behavior and it encompasses changes in internal states insofar as they pertain to what organisms do. Some definitions go further, focusing on observation of organisms in their environment. Bartholomew, A student of history, or a naturalist, studies the world by observing plants. A common thread in many definitions of natural history is the inclusion of a component, as seen in a recent definition by H. W. Greene

Antiquarian
–
An antiquarian or antiquary is an aficionado or student of antiquities or things of the past. More specifically, the term is used for those who study history with attention to ancient artifacts, archaeological and historic sites, or historic archives. Today the term is used in a pejorative sense, to refer to an excessively narrow focus on factual historical trivia. The Kaogutu or Illustrated Catalogue of Examined Antiquity compiled by Lü Dalin is one of the oldest known catalogues to systematically describe and classify ancient artifacts which were unearthed. Interests in antiquarian studies of ancient inscriptions and artifacts waned after the Song Dynasty, Books on antiquarian topics covered such subjects as the origin of customs, religious rituals, and political institutions, genealogy, topography and landmarks, and etymology. By contrast, antiquarian works as a form are organized by topic. Major antiquarian Latin writers with surviving works include Varro, Pliny the Elder, Aulus Gellius, the Roman emperor Claudius published antiquarian works, none of which is extant. Some of Ciceros treatises, particularly his work on divination, show strong antiquarian interests, roman-era Greek writers also dealt with antiquarian material, such as Plutarch in his Roman Questions and the Deipnosophistae of Athenaeus. The aim of Latin antiquarian works is to collect a number of possible explanations. The antiquarians are often used as sources by the ancient historians, despite the importance of antiquarian writing in the literature of ancient Rome, some scholars view antiquarianism as emerging only in the Middle Ages. Antiquarianisms wider flowering is more associated with the Renaissance, and with the critical assessment. The development of genealogy as a scientific discipline went hand-in-hand with the development of antiquarianism, genealogical antiquaries recognised the evidential value for their researches of non-textual sources, including seals and church monuments. Many early modern antiquaries were also chorographers, that is to say, they recorded landscapes, in England, some of the most important of these took the form of county histories. They increasingly argued that empirical evidence could be used to refine. Antiquaries had always attracted a degree of ridicule, and since the century the term has tended to be used most commonly in negative or derogatory contexts. Nevertheless, many practising antiquaries continue to claim the title with pride, Antiquary was the usual term in English from the 16th to the mid-18th centuries to describe a person interested in antiquities. From the second half of the 18th century, however, antiquarian began to be used widely as a noun. From the 16th to the 19th centuries, a distinction was perceived to exist between the interests and activities of the antiquary and the historian

Lutheranism
–
Lutheranism is a major branch of Protestant Christianity which identifies with the theology of Martin Luther, a German friar, ecclesiastical reformer and theologian. Luthers efforts to reform the theology and practice of the Catholic Church launched the Protestant Reformation in the German-speaking territories of the Holy Roman Empire. Lutheranism advocates a doctrine of justification by grace alone through faith alone on the basis of Scripture alone and this is in contrast to the belief of the Catholic Church, defined at the Council of Trent, concerning authority coming from both the Scriptures and Tradition. In addition, Lutheranism accepts the teachings of the first seven ecumenical councils of the undivided Christian Church, unlike Calvinism, Lutherans retain many of the liturgical practices and sacramental teachings of the pre-Reformation Church, with a particular emphasis on the Eucharist, or Lords Supper. Lutheran theology differs from Reformed theology in Christology, the purpose of Gods Law, the grace, the concept of perseverance of the saints. Today, Lutheranism is one of the largest denominations of Protestantism, with approximately 80 million adherents, it constitutes the third most common Protestant denomination after historically Pentecostal denominations and Anglicanism. The Lutheran World Federation, the largest communion of Lutheran churches, Other Lutheran organizations include the International Lutheran Council and the Confessional Evangelical Lutheran Conference, as well as independent churches. The name Lutheran originated as a term used against Luther by German Scholastic theologian Dr. Johann Maier von Eck during the Leipzig Debate in July 1519. Eck and other Catholics followed the practice of naming a heresy after its leader. Martin Luther always disliked the term Lutheran, preferring the term Evangelical, which was derived from euangelion, the followers of John Calvin, Huldrych Zwingli, and other theologians linked to the Reformed tradition also began to use that term. To distinguish the two groups, others began to refer to the two groups as Evangelical Lutheran and Evangelical Reformed. As time passed by, the word Evangelical was dropped, Lutherans themselves began to use the term Lutheran in the middle of the 16th century, in order to distinguish themselves from other groups such as the Philippists and Calvinists. In 1597, theologians in Wittenberg defined the title Lutheran as referring to the true church, Lutheranism has its roots in the work of Martin Luther, who sought to reform the Western Church to what he considered a more biblical foundation. Lutheranism spread through all of Scandinavia during the 16th century, as the monarch of Denmark–Norway, through Baltic-German and Swedish rule, Lutheranism also spread into Estonia and Latvia. Since 1520, regular Lutheran services have been held in Copenhagen, under the reign of Frederick I, Denmark-Norway remained officially Catholic. Although Frederick initially pledged to persecute Lutherans, he adopted a policy of protecting Lutheran preachers and reformers. During Fredericks reign, Lutheranism made significant inroads in Denmark, at an open meeting in Copenhagen attended by the king in 1536, the people shouted, We will stand by the holy Gospel, and do not want such bishops anymore. Fredericks son Christian was openly Lutheran, which prevented his election to the throne upon his fathers death, however, following his victory in the civil war that followed, in 1537 he became Christian III and advanced the Reformation in Denmark-Norway

Arnhem
–
Arnhem /ˈɑːrnəm/ or /ˈɑːrnhɛm/ is a city and municipality, situated in the eastern part of the Netherlands. It is the capital of the province of Gelderland and located on banks of the rivers Nederrijn and Sint-Jansbeek, which was the source of the citys development. Arnhem had a population of 151,356 in 2014 and is one of the cities of the Netherlands. The municipality is part of the city region Arnhem-Nijmegen, which has a combined 736,500 inhabitants, Arnhem is home to the Hogeschool van Arnhem en Nijmegen, ArtEZ Institute of the Arts, Netherlands Open Air Museum, Royal Burgers Zoo and National Sports Centre Papendal. The oldest archeological findings of human activity around Arnhem are two firestones of about 70,000 years ago and these come from the stone age, when the Neanderthals lived in this part of Europe. In Schuytgraaf, remnants of a camp from around 5000 BC have been discovered. In Schaarsbergen,12 grave mounds were found from 2400 BC, the earliest settlement in Arnhem dates from 1500 BC, of which traces have been found on the Hoogkamp, where the Van Goyenstraat is currently located. Arnhem arose on the location where the road between Nijmegen and Utrecht/Zutphen split, Seven streams provided the city with water, and only when the flow of the Rhine was changed in 1530, was the city located on the river. Arnhem was first mentioned as such in 893 as Arneym or Arentheym, in 1233 Count Otto II of Guelders from Zutphen, conferred city rights on the town, which had belonged to the abbey of Prüm, settled in, and fortified it. Arnhem entered the Hanseatic League in 1443, in 1473, it was captured by Charles the Bold of Burgundy. In 1514, Charles of Egmond, duke of Guelders, took it from the dukes of Burgundy, in 1543, as capital of the so-called Kwartier van Veluwe it joined the Union of Utrecht during the Eighty years war in 1579. After its capture from the Spanish forces by Dutch and English troops in 1585 the city part of the Republic of the Seven United Provinces of the Netherlands. The French occupied the town 1672–74, from 1795 to 1813, it was reoccupied by the French, by both revolutionary and imperial forces. In the early 19th century, the fortifications were almost completely dismantled. The Sabelspoort is the remaining part of the medieval walls. In the 19th century, Arnhem was a resort town famous for its picturesque beauty. It was known as het Haagje van het oosten, mainly because a number of former sugar barons or planters from the Indies settled there. Even now the city is famous for its parks and greenery, the urbanization in the north on hilly terrain is also quite unusual for the Netherlands

Gelderland
–
Gelderland is a province of the Netherlands, located in the central eastern part of the country. With a land area of nearly 5,000 km2, it is the largest province of the Netherlands and shares borders with six other provinces, however, both Nijmegen and Apeldoorn are larger cities, Nijmegen being the largest with nearly 170,000 inhabitants. Other major regional centres in Gelderland are Ede, Doetinchem, Zutphen, Tiel, Wageningen, Zevenaar, Gelderland had a population of just over two million in 2015. According to the Wichard saga, the city was named by the Lords of Pont who fought and they named the town they founded after the death rattle of the dragon, Gelre. Historically, the dates from states of the Holy Roman Empire. The County of Guelders arose out of the Frankish pagus Hamaland in the 11th century around castles near Roermond, the counts of Gelre acquired the Betuwe and Veluwe regions and, through marriage, the County of Zutphen. Thus the counts of Guelders laid the foundation for a power that, through control of the Rhine, Waal, Meuse. Further enlarged by the acquisition of the city of Nijmegen in the 13th century. After 1379, the duchy was ruled from Jülich and by the counts of Egmond, the duchy resisted Burgundian domination, but William, Duke of Jülich-Cleves-Berg was forced to cede it to Charles V in 1543, after which it formed part of the Burgundian-Habsburg hereditary lands. The duchy revolted with the rest of the Netherlands against Philip II of Spain, after the deposition of Philip II, its sovereignty was vested in the States of Gelderland, and the princes of Orange were stadtholders. In 1672, the province was occupied by Louis XIV and, in 1713. Part of the Batavian Republic, of Louis Bonaparte’s Kingdom of Holland, during the Second World War, it saw heavy fighting between Allied Paratroopers, British XXX Corps and the German II SS Panzer Corps, at the Battle of Arnhem

Catholic
–
The use of terms catholicism and catholicity is closely related to the use of term Catholic Church. The earliest evidence of the use of term is the Letter to the Smyrnaeans that Ignatius of Antioch wrote in about 108 to Christians in Smyrna. In 380, Emperor Theodosius I limited use of the term Catholic Christian exclusively to those who followed the faith as Pope Damasus I of Rome. Numerous other early writers including Cyril of Jerusalem, Augustine of Hippo further developed the use of the term catholic in relation to Christianity. In Christian theology, and specially in ecclesiology, terms Catholicism, when used with small c, terms catholicism and catholicity generally designate theological doctrine of the catholicity of the Church without denominational connotations. A common belief in Catholicism is institutional continuity with the early Christian church founded by Jesus Christ, many churches or communions of churches identify singularly or collectively as the authentic church. The Bishop of Rome was also considered to have the right to convene ecumenical councils, when the Imperial capital moved to Constantinople, Romes influence was sometimes challenged. The first great rupture in the Church followed this Council and they are often called Ancient Oriental Churches. The next major break was after the Council of Chalcedon and this Council repudiated Eutychian Monophysitism which stated that the divine nature completely subsumed the human nature in Christ. This Council declared that Christ, though one person, exhibited two natures without confusion, without change, without division, without separation and thus is both fully God and fully human, the next great rift within Christianity was in the 11th century. This division between the Western Church and the Eastern Church is called the East–West Schism, several eastern churches reunited, constituting some of the Eastern Catholic Churches. Liturgical and canonical practices vary between all these particular Churches constituting the Roman and Eastern Catholic Churches, in all these cases the beliefs and practices of Catholicism would be identical with the beliefs and practices of the Church in question. However, in Roman Catholicism, the term catholic is understood as to cover those who recognize and are in standing with the Magisterium. The sense given to the word by those who use it to distinguish their position from a Calvinistic or Puritan form of Protestantism. It is then meaningful to attempt to draw up a list of common characteristic beliefs, the Roman Catholic Church includes the 23 rites who recognize the Magisterium. Belief in the Real Presence of Christ in the Eucharist, the belief that Christ is made manifest in the elements of Holy Communion, possession of the threefold ordained ministry of Bishops, Priests and Deacons. Belief that the Church is the vessel and deposit of the fullness of the teachings of Jesus and this teaching is preserved in both written scripture and in unwritten tradition, neither being independent of the other. A belief in the necessity and efficacy of sacraments, liturgical and personal use of the Sign of the Cross The use of sacred images, candles, vestments and music, and often incense and water, in worship

Denmark
–
The term Danish Realm refers to the relationship between Denmark proper, the Faroe Islands and Greenland—three countries constituting the Kingdom of Denmark. The legal nature of the Kingdom of Denmark is fundamentally one of a sovereign state. The Faroe Islands and Greenland have been part of the Crown of Denmark since 1397 when the Kalmar Union was ratified, legal matters in The Danish Realm are subject to the Danish Constitution. Beginning in 1953, state law issues within The Danish Realm has been governed by The Unity of the Realm, a less formal name for The Unity of the Realm is the Commonwealth of the Realm. In 1978, The Unity of The Realm was for the first time referred to as rigsfællesskabet. The name caught on and since the 1990s, both The Unity of The Realm and The Danish Realm itself has increasingly been referred to as simply rigsfællesskabet in daily parlance. The Danish Constitution stipulates that the foreign and security interests for all parts of the Danish Realm are the responsibility of the Danish government, the Faroes received home rule in 1948 and Greenland did so in 1979. In 2005, the Faroes received a self-government arrangement, and in 2009 Greenland received self rule, the Danish Realms unique state of internal affairs is acted out in the principle of The Unity of the Realm. This principle is derived from Article 1 of the Danish Constitution which specifies that constitutional law applies equally to all areas of the Danish Realm, the Constitutional Act specifies that sovereignty is to continue to be exclusively with the authorities of the Realm. The language of Denmark is Danish, and the Danish state authorities are based in Denmark, the Kingdom of Denmarks parliament, with its 179 members, is located in the capital, Copenhagen. Two of the members are elected in each of Greenland and the Faroe Islands. The Government ministries are located in Copenhagen, as is the highest court, in principle, the Danish Realm constitutes a unified sovereign state, with equal status between its constituent parts. Devolution differs from federalism in that the powers of the subnational authority ultimately reside in central government. The Self-Government Arrangements devolves political competence and responsibility from the Danish political authorities to the Faroese, the Faroese and Greenlandic authorities administer the tasks taken over from the state, enact legislation in these specific fields and have the economic responsibility for solving these tasks. The Danish government provides a grant to the Faroese and the Greenlandic authorities to cover the costs of these devolved areas. The 1948 Home Rule Act of the Faroe Islands sets out the terms of Faroese home rule, the Act states. the Faroe Islands shall constitute a self-governing community within the State of Denmark. It establishes the government of the Faroe Islands and the Faroese parliament. The Faroe Islands were previously administered as a Danish county, the Home Rule Act abolished the post of Amtmand and these powers were expanded in a 2005 Act, which named the Faroese home government as an equal partner with the Danish government

Mathematician
–
A mathematician is someone who uses an extensive knowledge of mathematics in his or her work, typically to solve mathematical problems. Mathematics is concerned with numbers, data, quantity, structure, space, models, one of the earliest known mathematicians was Thales of Miletus, he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, the number of known mathematicians grew when Pythagoras of Samos established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was All is number. It was the Pythagoreans who coined the term mathematics, and with whom the study of mathematics for its own sake begins, the first woman mathematician recorded by history was Hypatia of Alexandria. She succeeded her father as Librarian at the Great Library and wrote works on applied mathematics. Because of a dispute, the Christian community in Alexandria punished her, presuming she was involved, by stripping her naked. Science and mathematics in the Islamic world during the Middle Ages followed various models and it was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. As these sciences received wider attention from the elite, more scholars were invited and funded to study particular sciences, an example of a translator and mathematician who benefited from this type of support was al-Khawarizmi. A notable feature of many working under Muslim rule in medieval times is that they were often polymaths. Examples include the work on optics, maths and astronomy of Ibn al-Haytham, the Renaissance brought an increased emphasis on mathematics and science to Europe. As time passed, many gravitated towards universities. Moving into the 19th century, the objective of universities all across Europe evolved from teaching the “regurgitation of knowledge” to “encourag productive thinking. ”Thus, seminars, overall, science became the focus of universities in the 19th and 20th centuries. Students could conduct research in seminars or laboratories and began to produce doctoral theses with more scientific content. According to Humboldt, the mission of the University of Berlin was to pursue scientific knowledge. ”Mathematicians usually cover a breadth of topics within mathematics in their undergraduate education, and then proceed to specialize in topics of their own choice at the graduate level. In some universities, a qualifying exam serves to test both the breadth and depth of an understanding of mathematics, the students, who pass, are permitted to work on a doctoral dissertation. Mathematicians involved with solving problems with applications in life are called applied mathematicians. Applied mathematicians are mathematical scientists who, with their knowledge and professional methodology. With professional focus on a variety of problems, theoretical systems

Physics
–
Physics is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental disciplines, the main goal of physics is to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy, Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the mechanisms of other sciences while opening new avenues of research in areas such as mathematics. Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs, the United Nations named 2005 the World Year of Physics. Astronomy is the oldest of the natural sciences, the stars and planets were often a target of worship, believed to represent their gods. While the explanations for these phenomena were often unscientific and lacking in evidence, according to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, and all Western efforts in the exact sciences are descended from late Babylonian astronomy. The most notable innovations were in the field of optics and vision, which came from the works of many scientists like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi and Avicenna. The most notable work was The Book of Optics, written by Ibn Al-Haitham, in which he was not only the first to disprove the ancient Greek idea about vision, but also came up with a new theory. In the book, he was also the first to study the phenomenon of the pinhole camera, many later European scholars and fellow polymaths, from Robert Grosseteste and Leonardo da Vinci to René Descartes, Johannes Kepler and Isaac Newton, were in his debt. Indeed, the influence of Ibn al-Haythams Optics ranks alongside that of Newtons work of the same title, the translation of The Book of Optics had a huge impact on Europe. From it, later European scholars were able to build the devices as what Ibn al-Haytham did. From this, such important things as eyeglasses, magnifying glasses, telescopes, Physics became a separate science when early modern Europeans used experimental and quantitative methods to discover what are now considered to be the laws of physics. Newton also developed calculus, the study of change, which provided new mathematical methods for solving physical problems. The discovery of new laws in thermodynamics, chemistry, and electromagnetics resulted from greater research efforts during the Industrial Revolution as energy needs increased, however, inaccuracies in classical mechanics for very small objects and very high velocities led to the development of modern physics in the 20th century. Modern physics began in the early 20th century with the work of Max Planck in quantum theory, both of these theories came about due to inaccuracies in classical mechanics in certain situations. Quantum mechanics would come to be pioneered by Werner Heisenberg, Erwin Schrödinger, from this early work, and work in related fields, the Standard Model of particle physics was derived. Areas of mathematics in general are important to this field, such as the study of probabilities, in many ways, physics stems from ancient Greek philosophy

Tangent
–
In geometry, the tangent line to a plane curve at a given point is the straight line that just touches the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve, a similar definition applies to space curves and curves in n-dimensional Euclidean space. Similarly, the tangent plane to a surface at a point is the plane that just touches the surface at that point. The concept of a tangent is one of the most fundamental notions in geometry and has been extensively generalized. The word tangent comes from the Latin tangere, to touch, euclid makes several references to the tangent to a circle in book III of the Elements. In Apollonius work Conics he defines a tangent as being a line such that no other straight line could fall between it and the curve, archimedes found the tangent to an Archimedean spiral by considering the path of a point moving along the curve. Independently Descartes used his method of normals based on the observation that the radius of a circle is always normal to the circle itself and these methods led to the development of differential calculus in the 17th century. Many people contributed, Roberval discovered a method of drawing tangents. René-François de Sluse and Johannes Hudde found algebraic algorithms for finding tangents, further developments included those of John Wallis and Isaac Barrow, leading to the theory of Isaac Newton and Gottfried Leibniz. An 1828 definition of a tangent was a line which touches a curve. This old definition prevents inflection points from having any tangent and it has been dismissed and the modern definitions are equivalent to those of Leibniz who defined the tangent line as the line through a pair of infinitely close points on the curve. The tangent at A is the limit when point B approximates or tends to A, the existence and uniqueness of the tangent line depends on a certain type of mathematical smoothness, known as differentiability. At most points, the tangent touches the curve without crossing it, a point where the tangent crosses the curve is called an inflection point. Circles, parabolas, hyperbolas and ellipses do not have any point, but more complicated curves do have, like the graph of a cubic function. Conversely, it may happen that the curve lies entirely on one side of a line passing through a point on it. This is the case, for example, for a passing through the vertex of a triangle. In convex geometry, such lines are called supporting lines, the geometrical idea of the tangent line as the limit of secant lines serves as the motivation for analytical methods that are used to find tangent lines explicitly. The question of finding the tangent line to a graph, or the tangent line problem, was one of the central questions leading to the development of calculus in the 17th century, suppose that a curve is given as the graph of a function, y = f

Secant line
–
In geometry, a secant of a curve is a line that intersects two points on the curve. A chord is the interval of a secant that lies between the points at which it intersects the curve, the word secant comes from the Latin word secare, meaning to cut. A secant may be used to approximate the tangent to a curve, at some point P. If the secant to a curve is defined by two points, P and Q, with P fixed and Q variable, as Q approaches P along the curve, the direction of the secant approaches that of the tangent at P. As a consequence, one could say that the limit, as Q approaches P, of the secants slope, in calculus, this idea is the basis of the geometric definition of the derivative

University of Copenhagen
–
The University of Copenhagen is the oldest university and research institution in Denmark. Founded in 1479 as a studium generale, it is the second oldest institution for education in Scandinavia after Uppsala University. The university has 23,473 undergraduate students,17,398 postgraduate students,2,968 doctoral students, the university has four campuses located in and around Copenhagen, with the headquarters located in central Copenhagen. Most courses are taught in Danish, however, many courses are offered in English. The university has several thousands of students, about half of whom come from Nordic countries. The university has had 8 alumni become Nobel laureates and has produced one Turing Award recipient, the rector, the prorector and the director of the university is appointed by the university board. The rector in turn appoints directors of the different parts of the central administration, the deans appoint heads of 50 departments. There is no faculty senate and faculty is not involved in the appointment of rector, deans, hence the university has no faculty governance, although there are elected Academic Boards at faculty level who advise the deans. The governing body manages a budget of about BDKK8.3. The University is organized into six faculties and about 100 departments, the University employs about 5,600 academic staff and 4,400 technical and administrative staff. The total number of enrolled students is about 40,000 annually, UCPH has established an international graduate talent program which provides grants for international Ph. D, students and a tenure track carrier system. UCPH operates about fifty master’s programmes taught in English, and has arranged about 150 exchange agreements with institutions and 800 Erasmus agreements. Each year there are about 1,700 incoming exchange students,2,000 outbound exchange students and 4,000 international degree-seeking students, about 3,000 Ph. D. students study there each year. South Campus – houses the Faculty of Humanities and a proportion of the Faculty of Science. In the winter of 2016–2017, the Faculty of Law and the Faculty of Theology will also move to South Campus, frederiksberg Campus – home to sections of the Faculty of Science and the Faculty of Health and Medical Sciences. The Faculty of Health and Medical Sciences and the Faculty of Science also use the Taastrup Campus, the Faculty of Science also has facilities in Helsingør, Hørsholm and Nødebo. The University of Copenhagen was founded in 1479 and is the oldest university in Denmark, between the closing of the Studium Generale in Lund in 1536 and the establishment of the University of Aarhus in the late 1920s, it was the only university in Denmark. The university became a centre of Roman Catholic theological learning, but also had faculties for the study of law, medicine, between 1675 and 1788, the university introduced the concept of degree examinations

Grammar school
–
The original purpose of medieval grammar schools was the teaching of Latin. Over time the curriculum was broadened, first to include Ancient Greek, and later English and other European languages, natural sciences, mathematics, history, geography, and other subjects. In the late Victorian era grammar schools were reorganised to provide secondary education throughout England and Wales, Grammar schools of these types were also established in British territories overseas, where they have evolved in different ways. With the move to comprehensive schools in the 1960s and 1970s, some grammar schools became fully independent and charged fees. In both cases, many of these schools kept grammar school in their names, more recently, a number of state grammar schools still retaining their selective intake gained academy status, meaning that they are independent of the Local Education Authority. Some parts of England retain forms of the Tripartite System, some of the remaining grammar schools can trace their histories to before the 16th century. The schools were attached to cathedrals and monasteries, teaching Latin – the language of the church – to future priests, other subjects required for religious work were occasionally added, including music and verse, astronomy and mathematics and law. With the foundation of the ancient universities from the late 12th century, grammar schools became the point to a liberal arts education. Pupils were usually educated in schools up to the age of 14, after which they would look to universities. An example of a grammar school founded by a medieval borough corporation unconnected with church or university is Bridgnorth Grammar School. During the English Reformation in the 16th century, most cathedral schools were closed and replaced by new foundations funded from the dissolution of the monasteries. For example, the oldest extant schools in Wales – Christ College, Brecon, with the increased emphasis on studying the scriptures after the Reformation, many schools added Greek and, in a few cases, Hebrew. The teaching of languages was hampered by a shortage of non-Latin type. Many of these are commemorated in annual Founders Day services and ceremonies at surviving schools. The usual pattern was to create an endowment to pay the wages of a master to instruct boys in Latin. The school day ran from 6 a. m. to 5 p. m. with a two-hour break for lunch, in winter, school started at 7 a. m. Most of the day was spent in the learning of Latin. To encourage fluency, some schoolmasters recommended punishing any pupil who spoke in English, by the end of their studies at age 14, they would be quite familiar with the great Latin authors, and with Latin drama and rhetoric

University of Marburg
–
The Philipp University of Marburg, was founded in 1527 by Philip I, Landgrave of Hesse as one of Germanys oldest universities, dating back to a Protestant foundation. As a state university it no longer has any religious affiliation and it was the main university of the principality of Hesse and remains a public university of that state. It now has about 25,000 students and 7,500 employees, making Marburg, a town of 72,000 inhabitants, though most subjects are grouped, the University of Marburg is not a campus university in the broader sense. About 12% of the students are international, the highest percentage in Hesse and it offers an International summer university programme every summer and has an awarded ERASMUS programme. Marburg is home to one of Germanys most traditional medical faculties, the German physicians union is called Marburger Bund. In 1609, the University of Marburg established the worlds first professorship in chemistry, in 2012 it opened the first German participative chemistry museum, called Chemicum. Its experimental course programme is aimed at encouraging people to pursue careers in science. 20 professors were expelled in 1933, among them Wilhelm Röpke who emigrated, the university is most famous for its life sciences research, but is also home to one of the few centers that conduct research on the middle east, the CNMS. The departments of psychology and geography enjoy a reputation and reached Excellence Group status in the Europe-wide CHE Excellence Ranking 2009. According to the 2012 QS Ranking, the university ranked among the top 30 German universities, the ARWU ranking which is more focused on research, ranks the university around 200, with its life sciences and social sciences department in the 151-200 range worldwide. The strong research is illustrated by its participation in several SFBs. These collaborative research centres are financed by the German Science Foundation DFG and they encourage researchers to cross the boundaries of disciplines, institutes, departments and faculties within the participating university. It retained that strength, especially in Philosophy and Theology for a time after World War II. S. S. Eliot Wilhelm Viëtor Historical detention room

University of Basel
–
The University of Basel is located in Basel, Switzerland. Founded on 3 April 1460, it is Switzerland’s oldest university and is counted among the institutions of the country. The associated University Library of Basel is the largest and among the most important libraries in the whole of Switzerland, in 2016, the University boasted 12852 students and 377 professors. International students accounted for 25 percent of the student body, the University of Basel was founded in connection with the Council of Basel. The deed of foundation given in the form of a Papal bull by Pope Pius II on November 12,1459, originally the University of Basel was decreed to have four faculties—arts, medicine, theology, and jurisprudence. The faculty of arts served until 1818 as the foundation for the three academic subjects. In the eighteenth century as Basel became more commercial, the university, one of the centers of learning in the Renaissance, enrollment which had been over a thousand around 1600, dropped to sixty in 1785 with eighteen professors. The professors themselves were mostly sons of the elite, over the course of centuries as many scholars came to the city, Basel became an early center of book printing and humanism. Around the same time as the university itself, the Basel University Library was founded, today it has over three million books and writings and is the largest library in Switzerland. The city, Basel-Stadt, had to buy back this share, students were expected to continue their education after two years or so at a German university. The Student Advice Center provides advice on academic programs and career opportunities. The Student Administration Office provides information on applications, grants, mobility, exchanges, there are also a variety of organizations that cater to international students, such as local chapters of Toastmasters and AIESEC, and associations that perform community services. There is a foreign affairs association, a Model United Nations team, there are also various religious groups. A number of student groups exist out of formal venues. Such associations include the Akademische Turnerschaft Alemannia zu Basel, AKW Raurica, Helvetia Basel, Jurassia Basiliensis, Schwizerhüsli, membership in many is restricted to men, though A. V. University Sports provides a gym, fitness classes, and sport and dance camps to students, the Studentische Körperschaft der Universität Basel speaks on behalf of the students and represents their needs and interests. It acts as a student representative and has no political or religious affiliations.

Latin
–
Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

Greek language
–
Greek is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean. It has the longest documented history of any living language, spanning 34 centuries of written records and its writing system has been the Greek alphabet for the major part of its history, other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems. Together with the Latin texts and traditions of the Roman world, during antiquity, Greek was a widely spoken lingua franca in the Mediterranean world and many places beyond. It would eventually become the official parlance of the Byzantine Empire, the language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, Turkey, and the Greek diaspora. Greek roots are used to coin new words for other languages, Greek. Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, the earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the worlds oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now extinct Anatolian languages, the Greek language is conventionally divided into the following periods, Proto-Greek, the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age, Mycenaean Greek, the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards, Ancient Greek, in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire, after the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, Medieval Greek, also known as Byzantine Greek, the continuation of Koine Greek in Byzantine Greece, up to the demise of the Byzantine Empire in the 15th century. Much of the written Greek that was used as the language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine. Modern Greek, Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period and it is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it. In the modern era, the Greek language entered a state of diglossia, the historical unity and continuing identity between the various stages of the Greek language is often emphasised. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language and it is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English, Greek is spoken by about 13 million people, mainly in Greece, Albania and Cyprus, but also worldwide by the large Greek diaspora. Greek is the language of Greece, where it is spoken by almost the entire population

Medicine
–
Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. The word medicine is derived from Latin medicus, meaning a physician, Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Medicine has existed for thousands of years, during most of which it was an art frequently having connections to the religious and philosophical beliefs of local culture. For example, a man would apply herbs and say prayers for healing, or an ancient philosopher. In recent centuries, since the advent of modern science, most medicine has become a combination of art, while stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science. Prescientific forms of medicine are now known as medicine and folk medicine. They remain commonly used with or instead of medicine and are thus called alternative medicine. For example, evidence on the effectiveness of acupuncture is variable and inconsistent for any condition, in contrast, treatments outside the bounds of safety and efficacy are termed quackery. Medical availability and clinical practice varies across the world due to differences in culture. In modern clinical practice, physicians personally assess patients in order to diagnose, treat, the doctor-patient relationship typically begins an interaction with an examination of the patients medical history and medical record, followed by a medical interview and a physical examination. Basic diagnostic medical devices are typically used, after examination for signs and interviewing for symptoms, the doctor may order medical tests, take a biopsy, or prescribe pharmaceutical drugs or other therapies. Differential diagnosis methods help to rule out conditions based on the information provided, during the encounter, properly informing the patient of all relevant facts is an important part of the relationship and the development of trust. The medical encounter is then documented in the record, which is a legal document in many jurisdictions. Follow-ups may be shorter but follow the general procedure. The diagnosis and treatment may take only a few minutes or a few weeks depending upon the complexity of the issue, the components of the medical interview and encounter are, Chief complaint, the reason for the current medical visit. They are in the patients own words and are recorded along with the duration of each one, also called chief concern or presenting complaint. History of present illness, the order of events of symptoms. Distinguishable from history of illness, often called past medical history

Christian IV of Denmark
–
Christian IV, sometimes colloquially referred to as Christian Firtal in Denmark and Christian Kvart or Quart in Norway, was king of Denmark-Norway and Duke of Holstein and Schleswig from 1588 to 1648. His 59-year reign is the longest of Danish monarchs, and of Scandinavian monarchies, a member of the house of Oldenburg, Christian began his personal rule of Denmark in 1596 at the age of 19. He is frequently remembered as one of the most popular, ambitious, Christian IV obtained for his kingdom a level of stability and wealth that was virtually unmatched elsewhere in Europe. He engaged Denmark in numerous wars, most notably the Thirty Years War, which devastated much of Germany, undermined the Danish economy and he renamed the Norwegian capital Oslo as Christiania after himself, a name used until 1925. Christian was born at Frederiksborg Castle in Denmark on 12 April 1577 as the child and eldest son of King Frederick II of Denmark–Norway. He was descended, through his mothers side, from king John of Denmark, at the time, Denmark was still an elective monarchy, so in spite of being the eldest son Christian was not automatically heir to the throne. However, in 1580, at the age of 3, his father had him elected Prince-Elect, at the death of his father on 4 April 1588, Christian was 11 years old. He succeeded to the throne, but as he was still under-age a regency council was set up to serve as the trustees of the power while Christian was still growing up. It was led by chancellor Niels Kaas and consisted of the Rigsraadet council members Peder Munk, Jørgen Ottesen Rosenkrantz and his mother Queen Dowager Sophie,30 years old, had wished to play a role in the government, but was denied by the Council. At the death of Niels Kaas in 1594, Jørgen Rosenkrantz took over leadership of the regency council, Christian continued his studies at Sorø Academy and received a good education with a reputation as a headstrong and talented student. In 1595, the Council of the Realm decided that Christian would soon be old enough to assume control of the reins of government. On 17 August 1596, at the age of 19, Christian signed his haandfæstning, twelve days later, on 29 August 1596, Christian IV was crowned at the Church of Our Lady in Copenhagen by the Bishop of Zealand, Peder Jensen Vinstrup. He was crowned with a new Danish Crown Regalia which had made for him by Dirich Fyring. On 30 November 1597, he married Anne Catherine of Brandenburg, Christian took an interest in many and varied matters, including a series of domestic reforms and improving Danish national armaments. New fortresses were constructed under the direction of Dutch engineers, the Danish navy, which in 1596 had consisted of but twenty-two vessels, in 1610 rose to sixty, some of them built after Christians own designs. The formation of a national army proved more difficult, up until the early 1620s, Denmarks economy profited from general boom conditions in Europe. This inspired Christian to initiate a policy of expanding Denmarks overseas trade and he founded a number of merchant cities, and supported the building of factories. He also built a number of buildings in Dutch Renaissance style

Embryology
–
Embryology is the branch of biology that studies the prenatal development of gametes, fertilization, and development of embryos and fetuses. Additionally, embryology encompasses the study of disorders that occur before birth. After cleavage, the cells, or morula, becomes a hollow ball, or blastula. In bilateral animals, the blastula develops in one of two ways that divides the whole animal kingdom into two halves. If in the blastula the first pore becomes the mouth of the animal, it is a protostome, the protostomes include most invertebrate animals, such as insects, worms and molluscs, while the deuterostomes include the vertebrates. In due course, the changes into a more differentiated structure called the gastrula. The middle layer, or mesoderm, gives rise to the muscles, skeleton if any, the outer layer of cells, or ectoderm, gives rise to the nervous system, including the brain, and skin or carapace and hair, bristles, or scales. Embryos in many species appear similar to one another in early developmental stages. The reason for this similarity is because species have an evolutionary history. These similarities among species are called homologous structures, which are structures that have the same or similar function and mechanism, Drosophila melanogaster, a fruit fly, is a model organism in biology on which much research into embryology has been done. Before fertilization, the female produces an abundance of mRNA - transcribed from the genes that encode bicoid protein. These mRNA molecules are stored to be used later in what become the developing embryo. The male and female Drosophila gametes exhibit anisogamy, the female gamete is larger than the male gamete because it harbors more cytoplasm and, within the cytoplasm, the female gamete contains an abundance of the mRNA previously mentioned. At fertilization, the male and female gametes fuse and then the nucleus of the male gamete fuses with the nucleus of the female gamete, note that before the gametes nuclei fuse, they are known as pronuclei. A series of nuclear divisions will occur without cytokinesis in the zygote to form a cell known as a syncytium. All the nuclei in the syncytium are identical, just as all the nuclei in every cell of any multicellular organism are identical in terms of the DNA sequence of the genome. Before the nuclei can differentiate in transcriptional activity, the embryo must be divided into segments, in each segment, a unique set of regulatory proteins will cause specific genes in the nuclei to be transcribed. The resulting combination of proteins will transform clusters of cells into early embryo tissues that will develop into multiple fetal

Wormian bones
–
Wormian bones, also known as intra sutural bones, are extra bone pieces that occur within a suture in the cranium. These are irregular isolated bones that appear in addition to the centers of ossification of the cranium and. They occur most frequently in the course of the lambdoid suture and they are also occasionally seen within the sagittal and coronal sutures. A large wormian bone at lambda is often called an Inca bone, another specific wormian bone, the pterion ossicle, sometimes exists between the sphenoidal angle of the parietal bone and the great wing of the sphenoid bone. They tend to vary in size and can be found on side of the skull. Usually, not more than several are found in a single individual, wormian bones are a marker for some diseases and important in the primary diagnosis of brittle bone disease, osteogenesis imperfecta. Wormian bones are named for Ole Worm, professor of anatomy at Copenhagen and he taught Latin, Greek, physics and medicine. His description of the extra-sutural bones contributed to the science of embryology, Human skull Google Books, Anatomy of the Human Body 00426 at CHORUS1543897135 at GPnotebook Photo Photo

Skull
–
The skull is a bony structure that forms the head of the skeleton in most vertebrates. It supports the structures of the face and provides a cavity for the brain. The skull is composed of two parts, the cranium and the mandible, in the human these two parts are the neurocranium and the viscerocranium or facial skeleton that includes the mandible as its largest bone. The skull forms the anterior most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, in the human these sensory structures are part of the facial skeleton. In some animals such as horned ungulates, the skull also has a function by providing the mount for the horns. The English word skull is probably derived from Old Norse skulle, while the Latin word cranium comes from the Greek root κρανίον, the skull is made up of a number of fused flat bones, and contains many foramina and processes, and several cavities or sinuses. For details and the constituent bones, see neurocranium and viscerocranium, the human skull is the bony structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain, like the skulls of other vertebrates, it protects the brain from injury. The skull consists of two parts, of different embryological origin—the neurocranium and the facial skeleton, the neurocranium forms the protective cranial cavity that surrounds and houses the brain and brainstem. The facial skeleton is formed by the supporting the face. Except for the mandible, all of the bones of the skull are joined together by sutures—synarthrodial joints formed by bony ossification, sometimes there can be extra bone pieces within the suture known as wormian bones or sutural bones. The human skull is considered to consist of twenty-two bones—eight cranial bones. In the neurocranium these are the bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones. The bones of the skeleton are the vomer, two nasal conchae, two nasal bones, two maxilla, the mandible, two palatine bones, two zygomatic bones, and two lacrimal bones. Some of these bones—the occipital, parietal, frontal, in the neurocranium, and the nasal, lacrimal, the skull also contains sinus cavities and numerous foramina. The sinuses are lined with respiratory epithelium and their known functions are the lessening of the weight of the skull, the aiding of resonance to the voice and the warming and moistening of the air drawn through the nasal cavity. The foramina are openings in the skull, the largest of these is the foramen magnum that allows the passage of the spinal cord as well as nerves and blood vessels. The many processes of the include the mastoid process and the zygomatic process

Suture (anatomy)
–
In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. Sutures are found in the skeletons or exoskeletons of a range of animals. Sutures are found in animals with hard parts from the Cambrian period to the present day, sutures were and are formed by several different methods, and they exist between hard parts that are made from several different materials. The skeletons of vertebrate animals are made of bone, in which the main ingredient is calcium phosphate. The skulls of most vertebrates consist of sets of plates held together by cranial sutures. These sutures are held mainly by Sharpeys fibers which grow from each bone into the adjoining one. The shells of most molluscs are made of carbonate, and of conchiolin. For more information, see Mollusc shell, in cephalopod mollusks which have external shells, the shell is divided into compartments by septa. The septa are joined to the shell by sutures formed by repeated invagination. The sutures are visible from the outside and often form complex, nearly all snail shells can be visualized as a tube of increasing diameter, closed at the small end, and spirally wrapped around a central axis. For more information, see Gastropod shell, each complete rotation of this spirally-arranged tube is called a whorl. The whorls of a shell usually overlap one another, forming a spire. Where the whorls overlap, there is usually a clear indentation and this indentation forms a visible line, which is continuous and reaches from the apex of the shell to the aperture, this line is the suture. Details of the suture are often useful in discriminating one species from another, for example, when an angulation of the whorls occurs, the space between it and the suture above it constitutes the area known as the shoulder of the shell. The shoulder angle may be simple or keeled, an may sometimes have nodes or spines A trilobites carapace consisted of calcite, in many species the cephalon had sutures running from back to front round the outside edges of the eyes. These sutures divided the cephalon into 3 pieces

Literature
–
Literature, in its broadest sense, is any single body of written works. Its Latin root literatura/litteratura was used to refer to all written accounts, developments in print technology have allowed an evergrowing distribution and proliferation of written works, culminating in electronic literature. There have been attempts to define literature. Simon and Delyse Ryan begin their attempt to answer the question What is Literature, with the observation, The quest to discover a definition for literature is a road that is much travelled, though the point of arrival, if ever reached, is seldom satisfactory. Most attempted definitions are broad and vague, and they change over time. In fact, the thing that is certain about defining literature is that the definition will change. Concepts of what is literature change over time as well, definitions of literature have varied over time, it is a culturally relative definition. In Western Europe prior to the century, literature as a term indicated all books. A more restricted sense of the term emerged during the Romantic period, contemporary debates over what constitutes literature can be seen as returning to the older, more inclusive notion of what constitutes literature. Cultural studies, for instance, takes as its subject of both popular and minority genres, in addition to canonical works. The value judgment definition of literature considers it to cover exclusively those writings that possess high quality or distinction and this sort of definition is that used in the Encyclopædia Britannica Eleventh Edition when it classifies literature as the best expression of the best thought reduced to writing. The formalist definition is that literature foregrounds poetic effects, it is the literariness or poetic of literature that distinguishes it from ordinary speech or other kinds of writing. Etymologically, the term derives from Latin literatura/litteratura learning, a writing, grammar, originally writing formed with letters, in spite of this, the term has also been applied to spoken or sung texts. Poetry is a form of art which uses aesthetic and rhythmic qualities of language to evoke meanings in addition to, or in place of. Possibly as a result of Aristotles influence, poetry before the century was usually less a technical designation for verse than a normative category of fictive or rhetorical art. As a form it may pre-date literacy, with the earliest works being composed within and sustained by an oral tradition, novel, a long fictional prose narrative. It was the close relation to real life that differentiated it from the chivalric romance, in most European languages the equivalent term is roman. In English, the term emerged from the Romance languages in the fifteenth century, with the meaning of news, it came to indicate something new

Scandinavian languages
–
The language group is sometimes referred to as the Nordic languages, a direct translation of the most common term used among Danish, Swedish and Norwegian scholars and laypeople. Approximately 20 million people in the Nordic countries have a Scandinavian language as their native language, languages belonging to the North Germanic language tree are spoken commonly on Greenland and, to a lesser extent, by immigrants in North America. Dialects with the assigned to the northern group formed from the Proto-Germanic language in the late Pre-Roman Iron Age in Northern Europe. At last around the year 200 AD, speakers of the North Germanic branch became distinguishable from the other Germanic language speakers, the early development of this language branch is attested through runic inscriptions. The original vowel remained when nasalised *ōn and when before /z/, Proto-Germanic *geƀō ‘gift’ > Northwest Germanic *geƀu >, North Germanic *gjavu > with u-umlaut *gjǫvu > ON gjǫf, and West Germanic *gebu > OE giefu, cf. Goth giba. Proto-Germanic *tungōn ‘tongue’ > late Northwest Germanic *tungā > *tunga > ON tunga, OHG zunga, OE tunge, vs. Goth tuggō. *geƀōz ‘of a gift’ > late Northwest Germanic *geƀāz >, North Germanic *gjavaz > ON gjafar, the rhotacism of /z/ to /r/, with presumably a rhotic fricative of some kind as an earlier stage. This change probably affected West Germanic much earlier and then spread from there to North Germanic and this is confirmed by an intermediate stage ʀ, clearly attested in late runic East Norse at a time when West Germanic had long merged the sound with /r/. The development of the demonstrative pronoun ancestral to English this, Germanic *sa, sō, þat ‘this, that’ + proximal *si ‘here’, Runic Norse, nom. sg. þeim-si, etc. with declension of the 1st part, fixed form with declension on the 2nd part, ON sjá, þessi m. Some innovations are not found in West and East Germanic such as, Sharpening of geminate /jj/ and /ww/ according to Holtzmanns law Occurred also in East Germanic, Proto-Germanic *twajjôN > Old Norse tveggja, Gothic twaddjē, but > Old High German zweiio Word-final devoicing of stop consonants. Proto-Germanic *nahtuN > *nāttu > *nǭttu > Old Norse nótt /ɑi̯/ > /ɑː/ before /r/ Proto-Germanic *sairaz > *sāraz > *sārz > Old Norse sárr, with original /z/ Proto-Germanic *gaizaz > *geizz > Old Norse geirr. General loss of word-final /n/, following the loss of short vowels. Proto-Germanic *bindanaN > *bindan > Old Norse binda, but > Old English bindan and this also affected stressed syllables, Proto-Germanic *in > Old Norse í Vowel breaking of /e/ to /jɑ/ except after w, j or l. The diphthong /eu/ was also affected, shifting to /jɒu/ at an early stage and this diphthong is preserved in Old Gutnish and survives in modern Gutnish. In other Norse dialects, the /j/-onset and length remained, the word *ek, which could occur both stressed and unstressed, appears varyingly as ek and jak throughout Old Norse. Loss of initial /j/, and also of /w/ before a round vowel, Proto-Germanic *wulfaz > North Germanic ulfz > Old Norse ulfr The development of u-umlaut, which rounded stressed vowels when /u/ or /w/ followed in the next syllable. This followed vowel breaking, with ja /jɑ/ being u-umlauted to jǫ /jɒ/, Norwegian settlers brought Old West Norse to Iceland and the Faroe Islands around 800

Runestone
–
A runestone is typically a raised stone with a runic inscription, but the term can also be applied to inscriptions on boulders and on bedrock. The tradition began in the 4th century and lasted into the 12th century, most runestones are located in Scandinavia, but there are also scattered runestones in locations that were visited by Norsemen during the Viking Age. Runestones are often memorials to dead men, Runestones were usually brightly coloured when erected, though this is no longer evident as the colour has worn off. The tradition of raising stones that had runic inscriptions first appeared in the 4th and 5th century, in Norway and Sweden, the earliest Danish runestones appeared in the 8th and 9th centuries, and there are about 50 runestones from the Migration Period in Scandinavia. Most runestones were erected during the period 950-1100 CE, and then they were raised in Sweden. —The Ynglinga saga What may have increased the spread of runestones was an event in Denmark in the 960s, King Harald Bluetooth had just been baptised and in order to mark the arrival of a new order and a new age, he commanded the construction of a runestone. The runestone has three sides of two are decorated with images. On one side, there is an animal that is the prototype of the animals that would be commonly engraved on runestones. Shortly after this stone had been made, something happened in Scandinavias runic tradition, scores of chieftains and powerful Norse clans consciously tried to imitate King Harald, and from Denmark a runestone wave spread northwards through Sweden. In most districts, the fad died out after a generation, but, in the central Swedish provinces of Uppland and Södermanland, there are about 3,000 runestones among the about 6,000 runic inscriptions in Scandinavia. The runestones are unevenly distributed in Scandinavia, Denmark has 250 runestones, Sweden has as many as between 1,700 and 2,500 depending on definition. The Swedish district of Uppland has the highest concentration with as many as 1,196 inscriptions in stone, outside of Scandinavia, the Isle of Man stands out with its 30 runestones from the 9th century and early 11th century. Scattered runestones have also found in England, Ireland, Scotland. Runestones were placed on selected spots in the landscape, such as locations, roads, bridge constructions. In medieval churches, there are often runestones that have been inserted as construction material, in southern Scania, runestones can be tied to large estates that also had churches constructed on their land. In the Mälaren Valley, the appear to be placed so that they mark essential parts of the domains of an estate, such as courtyard, grave field. Runestones usually appear as single monuments and more rarely as pairs, in some cases, they are part of larger monuments together with other raised stones. However, although scholars know where 95% of all runestones were discovered, the remainder have been found in churches, roads, bridges, graves, farms, and water routes

Runes
–
The Scandinavian variants are also known as futhark or fuþark, the Anglo-Saxon variant is futhorc or fuþorc. Runology is the study of the runic alphabets, runic inscriptions, runestones, runology forms a specialised branch of Germanic linguistics. The earliest runic inscriptions date from around 150 AD, the characters were generally replaced by the Latin alphabet as the cultures that had used runes underwent Christianisation, by approximately 700 AD in central Europe and 1100 AD in northern Europe. However, the use of runes persisted for specialized purposes in northern Europe, until the early 20th century, runes were used in rural Sweden for decorative purposes in Dalarna and on Runic calendars. The three best-known runic alphabets are the Elder Futhark, the Anglo-Saxon Futhorc, and the Younger Futhark, the Younger Futhark is divided further into the long-branch runes, short-branch or Rök runes, and the stavlösa or Hälsinge runes. The Younger Futhark developed further into the Medieval runes, and the Dalecarlian runes, historically, the runic alphabet is a derivation of the Old Italic scripts of antiquity, with the addition of some innovations. Which variant of the Old Italic family in particular gave rise to the runes is uncertain, suggestions include Raetic, Venetic, Etruscan, or Old Latin as candidates. At the time, all of these scripts had the same angular letter shapes suited for epigraphy, the process of transmission of the script is unknown. The oldest inscriptions are found in Denmark and northern Germany, not near Italy, a West Germanic hypothesis suggests transmission via Elbe Germanic groups, while a Gothic hypothesis presumes transmission via East Germanic expansion. The runes were in use among the Germanic peoples from the 1st or 2nd century AD, no distinction is made in surviving runic inscriptions between long and short vowels, although such a distinction was certainly present phonologically in the spoken languages of the time. Similarly, there are no signs for labiovelars in the Elder Futhark The term runes is used to distinguish these symbols from Latin and it is attested on a 6th-century Alamannic runestaff as runa and possibly as runo on the 4th-century Einang stone. The name comes from the Germanic root run-, meaning secret or whisper, in Old Irish Gaelic, the word rún means mystery, secret, intention or affectionate love. Similarly in Welsh and Old English, the word rhin and rūn respectively means mystery, secret, secret writing, or sometimes in the sense of the word. Ogham is a Celtic script, similarly carved in the Norse manner, the root run- can also be found in the Baltic languages, meaning speech. In Lithuanian, runoti means both to cut and to speak, according to another theory, the Germanic root comes from the Indoeuropean root *reuə- dig. The Finnish term for rune, riimukirjain, means scratched letter, the Finnish word runo means poem and comes from the same source as the English word rune, it is a very old loan of the Proto-Germanic *rūnō. The runes developed centuries after the Old Italic alphabets from which they are historically derived. The formation of the Elder Futhark was complete by the early 5th century, specifically, the Raetic alphabet of Bolzano is often advanced as a candidate for the origin of the runes, with only five Elder Futhark runes having no counterpart in the Bolzano alphabet

Bishop
–
A bishop is an ordained, consecrated, or appointed member of the Christian clergy who is generally entrusted with a position of authority and oversight. Within these churches, bishops are seen as those who possess the full priesthood, Some Protestant churches including the Lutheran and Methodist churches have bishops serving similar functions as well, though not always understood to be within apostolic succession in the same way. Priests, deacons and lay ministers cooperate and assist their bishop in shepherding a flock, the earliest organization of the Church in Jerusalem was, according to most scholars, similar to that of Jewish synagogues, but it had a council or college of ordained presbyters. In, we see a system of government in Jerusalem chaired by James the Just. In, the Apostle Paul ordains presbyters in churches in Anatolia, in Timothy and Titus in the New Testament a more clearly defined episcopate can be seen. We are told that Paul had left Timothy in Ephesus and Titus in Crete to oversee the local church, Paul commands Titus to ordain presbyters/bishops and to exercise general oversight, telling him to rebuke with all authority. Early sources are unclear but various groups of Christian communities may have had the bishop surrounded by a group or college functioning as leaders of the local churches, eventually, as Christendom grew, bishops no longer directly served individual congregations. Instead, the Metropolitan bishop appointed priests to each congregation. Around the end of the 1st century, the organization became clearer in historical documents. While Ignatius of Antioch offers the earliest clear description of monarchial bishops he is an advocate of monepiscopal structure rather than describing an accepted reality. To the bishops and house churches to which he writes, he offers strategies on how to pressure house churches who dont recognize the bishop into compliance. Other contemporary Christian writers do not describe monarchial bishops, either continuing to equate them with the presbyters or speaking of episkopoi in a city, plainly therefore we ought to regard the bishop as the Lord Himself — Epistle of Ignatius to the Ephesians 6,1. Your godly bishop — Epistle of Ignatius to the Magnesians 2,1, therefore as the Lord did nothing without the Father, either by Himself or by the Apostles, so neither do ye anything without the bishop and the presbyters. — Epistle of Ignatius to the Magnesians 7,1. Be obedient to the bishop and to one another, as Jesus Christ was to the Father, and as the Apostles were to Christ and to the Father, — Epistle of Ignatius to the Magnesians 13,2. Apart from these there is not even the name of a church, — Epistle of Ignatius to the Trallesians 3,1. Follow your bishop, as Jesus Christ followed the Father, and the presbytery as the Apostles, and to the deacons pay respect, as to Gods commandment — Epistle of Ignatius to the Smyrnans 8,1. He that honoureth the bishop is honoured of God, he that doeth aught without the knowledge of the bishop rendereth service to the devil — Epistle of Ignatius to the Smyrnans 9,1

Norway
–
The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the Kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land, until 1814, the kingdom included the Faroe Islands, Greenland, and Iceland. It also included Isle of Man until 1266, Shetland and Orkney until 1468, Norway has a total area of 385,252 square kilometres and a population of 5,258,317. The country shares a long border with Sweden. Norway is bordered by Finland and Russia to the north-east, Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. King Harald V of the Dano-German House of Glücksburg is the current King of Norway, erna Solberg became Prime Minister in 2013, replacing Jens Stoltenberg. A constitutional monarchy, Norway divides state power between the Parliament, the Cabinet and the Supreme Court, as determined by the 1814 Constitution, the kingdom is established as a merger of several petty kingdoms. By the traditional count from the year 872, the kingdom has existed continuously for 1,144 years, Norway has both administrative and political subdivisions on two levels, counties and municipalities. The Sámi people have an amount of self-determination and influence over traditional territories through the Sámi Parliament. Norway maintains close ties with the European Union and the United States, the country maintains a combination of market economy and a Nordic welfare model with universal health care and a comprehensive social security system. Norway has extensive reserves of petroleum, natural gas, minerals, lumber, seafood, the petroleum industry accounts for around a quarter of the countrys gross domestic product. On a per-capita basis, Norway is the worlds largest producer of oil, the country has the fourth-highest per capita income in the world on the World Bank and IMF lists. On the CIAs GDP per capita list which includes territories and some regions, from 2001 to 2006, and then again from 2009 to 2017, Norway had the highest Human Development Index ranking in the world. It also has the highest inequality-adjusted ranking, Norway ranks first on the World Happiness Report, the OECD Better Life Index, the Index of Public Integrity and the Democracy Index. Norway has two names, Noreg in Nynorsk and Norge in Bokmål. The name Norway comes from the Old English word Norðrveg mentioned in 880, meaning way or way leading to the north. In contrasting with suðrvegar southern way for Germany, and austrvegr eastern way for the Baltic, the Anglo-Saxon of Britain also referred to the kingdom of Norway in 880 as Norðmanna land. This was the area of Harald Fairhair, the first king of Norway, and because of him

Runamo
–
Runamo is a cracked dolerite dike that was for centuries held to be a runic inscription and gave rise to a famous scholarly controversy in the 19th century. It is located 2.7 km from the church of Bräkne-Hoby in Blekinge, Sweden. For hundreds of people said it was possible to read an inscription. As early as the 12th century, the Danish chronicler Saxo Grammaticus reported in the introduction to his Gesta Danorum that the inscription was no longer legible being too worn down. There was considerable interest in the inscription during the Gothicismus of the early 19th century, the Swedish writer Esaias Tegnér referred to it in his unfinished poem on the giantess Gerðr and Axel who became bishop Absalon of Lund. In 1833, the Royal Danish Academy of Sciences and Letters sent an expedition led by an Icelandic professor at the University of Copenhagen named Finnur Magnússon, the mission was to explore the signs making use of geological and artistic expertise, including the geologist Johan Georg Forchhammer. At first, Finnur was unable to read the signs, but resolving to read them from right to left and by interpreting most of them as bind runes, he believed he discerned a poem. Finnurs report prompted the famous Swedish scientist Jöns Jacob Berzelius to undertake his own study in 1836, since then, it is generally considered to be a dolerite dike with cracks.

Lund
–
Lund is a city in the province of Scania, southern Sweden. The town had 87,244 inhabitants in 2015, out of a total of 118,150 in 2016. It is the seat of Lund Municipality, Skåne County, Lund is believed to have been founded around 990, when Scania belonged to Denmark. From 1103 it was the see of the Catholic Metropolitan Archdiocese of Lund, Lund was transferred to Sweden following the signing of the Treaty of Roskilde in 1658. It was temporarily the capital of Sweden between 1716 and 1718, Lund University, established 1666, is today one of Scandinavias largest institutions for education and research. The university and its buildings dominate much of the centre of the city, numerous literary and intellectual figures have lived or studied in Lund, including the writer August Strindberg and the scientist and naturalist Carl Linnaeus. Along with Sigtuna, Lund is the oldest city in present-day Sweden, until the 1980s, the town was thought to have been founded around 1020 by either Sweyn I Forkbeard or his son Canute the Great of Denmark. The area was part of the kingdom of Denmark. But, recent archaeological discoveries suggest that the first settlement dated to circa 990, the Uppåkra settlement dates back to the first century B. C. and its remains are at the present site of the village of Uppåkra. King Sweyn I Forkbeard moved Lund to its present location, a distance of five kilometres. The new location of Lund, on a hill and across a ford, gave the new site considerable defensive advantages in comparison with Uppåkra, the diocese of nearby Dalby was absorbed in 1066. Lund Cathedral was similarly founded in or shortly after 1103, in 1152, the Norwegian archdiocese of Nidaros was founded as a separate province of the church, independent of Lund. In 1164 Sweden also acquired an archbishop of its own, although he was subordinate to the archbishop of Lund. It is still, as the diocese of Lund, a diocese in the Church of Sweden, Lund Cathedral School was founded in 1085 by the Danish king Canute the Saint. This is the oldest school in Scandinavia and one of the oldest in Northern Europe, many prominent people were educated there, among them the actor Max von Sydow and several high-ranking politicians. In 1658, the Scanian lands were ceded by Denmark to Sweden by the Treaty of Roskilde, on December 4,1676 Lund was defended in the Battle of Lund, one of the bloodiest battles fought in Scandinavia. Lund University, established in 1666, is Swedens largest, with 42,000 full or part-time students, the figure includes Lund Institute of Technology, which is to some extent independent of the old university. As late as the 1940s, Lund was a small city with few large-scale industries, covering only about a quarter of the current urban area, and dominated by the cathedral

Cabinet of curiosities
–
Cabinets of curiosities were encyclopedic collections of objects whose categorical boundaries were, in Renaissance Europe, yet to be defined. Modern terminology would categorize the objects included as belonging to natural history, geology, ethnography, archaeology, religious or historical relics, works of art, the Kunstkammer was regarded as a microcosm or theater of the world, and a memory theater. The Kunstkammer conveyed symbolically the patrons control of the world through its indoor, the term cabinet originally described a room rather than a piece of furniture. The classic cabinet of curiosities emerged in the century, although more rudimentary collections had existed earlier. The earliest pictorial record of a natural history cabinet is the engraving in Ferrante Imperatos DellHistoria Naturale, some of the volumes doubtless represent his herbarium. Every surface of the ceiling is occupied with preserved fishes, stuffed mammals and curious shells. Examples of corals stand on the bookcases, above them, stuffed birds stand against panels inlaid with square polished stone samples, doubtless marbles and jaspers or fitted with pigeonhole compartments for specimens. Below them, a range of cupboards contain specimen boxes and covered jars, two of the most famously described seventeenth-century cabinets were those of Ole Worm, known as Olaus Wormius, and Athanasius Kircher. Often they would contain a mix of fact and fiction, including apparently mythical creatures, Worms collection contained, for example, what he thought was a Scythian Lamb, a woolly fern thought to be a plant/sheep fabulous creature. However he was responsible for identifying the narwhals tusk as coming from a whale rather than a unicorn. The specimens displayed were often collected during exploring expeditions and trading voyages, Cabinets of curiosities would often serve scientific advancement when images of their contents were published. The catalog of Worms collection, published as the Museum Wormianum, used the collection of artifacts as a point for Worms speculations on philosophy, science, natural history. Cabinets of curiosities were limited to those who could afford to create, many monarchs, in particular, developed large collections. A rather under-used example, stronger in art than other areas, was the Studiolo of Francesco I, frederick III of Denmark, who added Worms collection to his own after Worms death, was another such monarch. A third example is the Kunstkamera founded by Peter the Great in Saint Petersburg in 1714, many items were bought in Amsterdam from Albertus Seba and Frederik Ruysch. The fabulous Habsburg Imperial collection included important Aztec artifacts, including the feather head-dress or crown of Montezuma now in the Museum of Ethnology, similar collections on a smaller scale were the complex Kunstschränke produced in the early seventeenth century by the Augsburg merchant, diplomat and collector Philipp Hainhofer. The best preserved example is the one given by the city of Augsburg to King Gustavus Adolphus of Sweden in 1632, the curio cabinet, as a modern single piece of furniture, is a version of the grander historical examples. In 1714, Michael Bernhard Valentini published an early work, Museum Museorum

Natural philosophy
–
Natural philosophy or philosophy of nature was the philosophical study of nature and the physical universe that was dominant before the development of modern science. It is considered to be the precursor of natural science, from the ancient world, starting with Aristotle, to the 19th century, the term natural philosophy was the common term used to describe the practice of studying nature. Even in the 19th century, a treatise by Lord Kelvin and Peter Guthrie Tait, in the German tradition, Naturphilosophie persisted into the 18th and 19th century as an attempt to achieve a speculative unity of nature and spirit. Some of the greatest names in German philosophy are associated with movement, including Goethe, Hegel. The term natural philosophy preceded our current natural science, empirical science historically developed out of philosophy or, more specifically, natural philosophy. In the 14th and 15th centuries, natural philosophy was one of many branches of philosophy, the first person appointed as a specialist in Natural Philosophy per se was Jacopo Zabarella, at the University of Padua in 1577. Modern meanings of the science and scientists date only to the 19th century. Before that, science was a synonym for knowledge or study, the term gained its modern meaning when experimental science and the scientific method became a specialized branch of study apart from natural philosophy. In general, chairs of Natural Philosophy established long ago at the oldest universities are nowadays occupied mainly by physics professors. Even in the 19th century, a treatise by Lord Kelvin and Peter Guthrie Tait, in Platos earliest known dialogue, Charmides distinguishes between science or bodies of knowledge that produce a physical result, and those that do not. Natural philosophy has been categorized as a rather than a practical branch of philosophy. Sciences that guide arts and draw on the knowledge of nature may produce practical results. The study of natural philosophy seeks to explore the cosmos by any means necessary to understand the universe, some ideas presuppose that change is a reality. George Santayana, in his Scepticism and Animal Faith, attempted to show that the reality of change cannot be proven. If his reasoning is sound, it follows that to be a physicist, one must restrain ones skepticism enough to trust ones senses, rené Descartes metaphysical system of Cartesian Dualism describes two kinds of substance, matter and mind. Humankinds mental engagement with nature certainly predates civilization and the record of history, Philosophical, and specifically non-religious thought about the natural world, goes back to ancient Greece. These lines of thought began before Socrates, who turned from his studies from speculations about nature to a consideration of man. The thought of philosophers such Parmenides, Heraclitus, and Democritus centered on the natural world

Taxidermy
–
Taxidermy is the preserving of an animals body via stuffing or mounting for the purpose of display or study. Animals are often, but not always, portrayed in a life-like state, the word taxidermy refers to the process of preserving the animal, but the word is also used to describe the end product, which are often called mounts. The word taxidermy is derived from the Greek words taxis and derma, taxis means to to move, and derma means skin. The word taxidermy translates to arrangement of skin, Taxidermy is practiced primarily on vertebrates but can also be done to larger insects and arachnids under some circumstances. Taxidermy takes on a number of forms and purposes, including natural history displays, hunting trophies, study skins. A person who practices taxidermy is called a taxidermist and they may practice professionally for museums or as businesses catering to hunters and fishermen, or as amateurs, such as hobbyists, hunters, and fishermen. A taxidermist is aided by familiarity with anatomy, sculpture, painting, preserving animal skins has been practiced for a long time. Embalmed animals have been found with Egyptian mummies, although embalming incorporates the use of lifelike poses, it is not considered taxidermy. In the Middle Ages, crude examples of taxidermy were displayed by astrologers, the earliest methods of preservation of birds for natural history cabinets were published in 1748 by Reaumur in France. Techniques for mounting were described in 1752 by M. B, there were several pioneers of taxidermy in France, Germany, Denmark and England around this time. For a while, clay was used to some of the soft parts. By the 18th century, almost every town had a tannery business, in the 19th century, hunters began bringing their trophies to upholstery shops, where the upholsterers would actually sew up the animal skins and stuff them with rags and cotton. The term stuffing or a stuffed animal evolved from this form of taxidermy. Professional taxidermists prefer the term mounting to stuffing, more sophisticated cotton-wrapped wire bodies supporting sewn-on cured skins soon followed. In France, Louis Dufresne, taxidermist at the Muséum national dHistoire naturelle from 1793 and this technique enabled the museum to build the greatest collection of birds in the world. Ward established one of the earliest taxidermy firms, Rowland Ward Ltd. of Picadilly, however, the art of taxidermy remained relatively undeveloped, and the specimens that were created remained stiff and unconvincing. The golden age of taxidermy was during the Victorian era, when mounted animals became a part of interior design. The father of modern taxidermy is considered to be John Hancock, an avid collector of birds, which he would shoot himself, he began modelling them with clay and casting in plaster

Fossil
–
Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous rock formations and sedimentary layers is known as the fossil record. The study of fossils across geological time, how they were formed, such a preserved specimen is called a fossil if it is older than some minimum age, most often the arbitrary date of 10,000 years. The observation that fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century. The development of dating techniques in the early 20th century allowed geologists to determine the numerical or absolute age of the various strata. Like extant organisms, fossils vary in size from microscopic, even single bacterial cells one micrometer in diameter, to gigantic, such as dinosaurs, Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces. These types of fossil are called trace fossils, as opposed to body fossils, finally, past life leaves some markers that cannot be seen but can be detected in the form of biochemical signals, these are known as chemofossils or biosignatures. The process of fossilization varies according to type and external conditions. Permineralization is a process of fossilization that occurs when an organism is buried, the empty spaces within an organism become filled with mineral-rich groundwater. Minerals precipitate from the groundwater, occupying the empty spaces and this process can occur in very small spaces, such as within the cell wall of a plant cell. Small scale permineralization can produce very detailed fossils, for permineralization to occur, the organism must become covered by sediment soon after death or soon after the initial decay process. The degree to which the remains are decayed when covered determines the later details of the fossil, some fossils consist only of skeletal remains or teeth, other fossils contain traces of skin, feathers or even soft tissues. This is a form of diagenesis, in some cases the original remains of the organism completely dissolve or are otherwise destroyed. The remaining organism-shaped hole in the rock is called an external mold, if this hole is later filled with other minerals, it is a cast. An endocast or internal mold is formed when sediments or minerals fill the cavity of an organism. This is a form of cast and mold formation. If the chemistry is right, the organism can act as a nucleus for the precipitation of minerals such as siderite, if this happens rapidly before significant decay to the organic tissue, very fine three-dimensional morphological detail can be preserved. Nodules from the Carboniferous Mazon Creek fossil beds of Illinois, USA, are among the best documented examples of such mineralization, replacement occurs when the shell, bone or other tissue is replaced with another mineral

Great auk
–
The great auk is a flightless bird of the alcid family that became extinct in the mid-19th century. It was the modern species in the genus Pinguinus. It bred on rocky, isolated islands with easy access to the ocean and a food supply. The great auk was 75 to 85 centimetres tall and weighed around 5 kilograms and it had a black back and a white belly. The black beak was heavy and hooked, with grooves on its surface, during summer, the great auks plumage showed a white patch over each eye. During winter, the auk lost these patches, instead developing a band stretching between the eyes. The wings were only 15 centimetres long, rendering the bird flightless, instead, the auk was a powerful swimmer, a trait that it used in hunting. Its favourite prey were fish, including Atlantic menhaden and capelin, although agile in the water, it was clumsy on land. Great auk pairs mated for life and they nested in extremely dense and social colonies, laying one egg on bare rock. The egg was white with brown marbling. Both parents incubated the egg for about six weeks before the young hatched, the young auk left the nest site after two or three weeks, although the parents continued to care for it. The great auk was an important part of many Native American cultures, many Maritime Archaic people were buried with great auk bones, and one was buried covered in over 200 auk beaks, which are assumed to have been part of a cloak made of their skins. Early European explorers to the Americas used the auk as a convenient food source or as fishing bait, the birds down was in high demand in Europe, a factor which largely eliminated the European populations by the mid-16th century. Scientists soon began to realize that the auk was disappearing and it became the beneficiary of many early environmental laws. Its growing rarity increased interest from European museums and private collectors in obtaining skins, on 3 July 1844, the last two confirmed specimens were killed on Eldey, off the coast of Iceland, which also eliminated the last known breeding attempt. Later reports of roaming individuals being seen or caught are unconfirmed, a record of a bird in 1852 is considered by some to be the last sighting of the species. The great auk is mentioned in novels and the scientific journal of the American Ornithologists Union is named The Auk in honour of this bird. Analysis of mtDNA sequences has confirmed morphological and biogeographical studies suggesting that the razorbill is the great auks closest living relative, the great auk was also closely related to the little auk, which underwent a radically different evolution compared to Pinguinus

Empiricism
–
Empiricism is a theory that states that knowledge comes only or primarily from sensory experience. It is one of several views of epistemology, the study of human knowledge, Empiricism in the philosophy of science emphasizes evidence, especially as discovered in experiments. Empiricism, often used by scientists, says that knowledge is based on experience. One of the epistemological tenets is that sensory experience creates knowledge, empirical research, including experiments and validated measurement tools, guides the scientific method. The term was used by the Empiric school of ancient Greek medical practitioners, a central concept in science and the scientific method is that it must be empirically based on the evidence of the senses. Both natural and social sciences use working hypotheses that are testable by observation, philosophical empiricists hold no knowledge to be properly inferred or deduced unless it is derived from ones sense-based experience. This view is contrasted with rationalism, which states that knowledge may be derived from reason independently of the senses. For example, John Locke held that knowledge could be arrived at through intuition. Similarly Robert Boyle, a prominent advocate of the experimental method, the main continental rationalists were also advocates of the empirical scientific method. Vaisheshika darshana, founded by the ancient Indian philosopher Kanada, accepted perception and this is enumerated in his work Vaiśeṣika Sūtra. The notion of tabula rasa connotes a view of mind as a blank or empty recorder on which experience leaves marks. This denies that humans have innate ideas, the image dates back to Aristotle, What the mind thinks must be in it in the same sense as letters are on a tablet which bears no actual writing, this is just what happens in the case of the mind. These notions contrasted with Platonic notions of the mind as an entity that pre-existed somewhere in the heavens. This idea was developed in ancient philosophy by the Stoic school. Stoic epistemology generally emphasized that the mind starts blank, but acquires knowledge as the world is impressed upon it. The doxographer Aetius summarizes this view as When a man is born, later stoics, such as Sextus of Chaeronea, would continue this idea of empiricism in later Stoic writings as well. As Sextus contends For every thought comes from sense-perception or not without sense-perception, so the immaterial active intellect, separate from any individual person, is still essential for understanding to occur. A similar Islamic theological novel, Theologus Autodidactus, was written by the Arab theologian and physician Ibn al-Nafis in the 13th century, during the 13th century Thomas Aquinas adopted the Aristotelian position that the senses are essential to mind into scholasticism

Unicorn
–
The unicorn is a legendary creature that has been described since antiquity as a beast with a single large, pointed, spiraling horn projecting from its forehead. The Bible also describes an animal, the reem, which some versions translate as unicorn, in European folklore, the unicorn is often depicted as a white horse-like or goat-like animal with a long horn and cloven hooves. In the Middle Ages and Renaissance, it was described as an extremely wild woodland creature, a symbol of purity and grace. In the encyclopedias its horn was said to have the power to render poisoned water potable, in medieval and Renaissance times, the tusk of the narwhal was sometimes sold as unicorn horn. The earliest description is from Ctesias, who in his book Indika described them as wild asses, fleet of foot, having a horn a cubit and a half in length, and colored white, red and black. Aristotle must be following Ctesias when he mentions two one-horned animals, the oryx and the so-called Indian ass, strabo says that in the Caucasus there were one-horned horses with stag-like heads. Cosmas Indicopleustes, a merchant of Alexandria who lived in the 6th century, made a voyage to India and he gives a description of a unicorn based on four brass figures in the palace of the King of Ethiopia. He states, from report, that it is impossible to take this ferocious beast alive, and that all its strength lies in its horn. When it finds itself pursued and in danger of capture, it throws itself from a precipice, and turns so aptly in falling, that it all the shock upon the horn. A one-horned animal is found on seals from the Indus Valley Civilization. Seals with such a design are thought to be a mark of social rank. Medieval knowledge of the fabulous beast stemmed from biblical and ancient sources, the predecessor of the medieval bestiary, compiled in Late Antiquity and known as Physiologus, popularized an elaborate allegory in which a unicorn, trapped by a maiden, stood for the Incarnation. As soon as the unicorn sees her, it lays its head on her lap and this became a basic emblematic tag that underlies medieval notions of the unicorn, justifying its appearance in every form of religious art. Interpretations of the myth focus on the medieval lore of beguiled lovers, whereas some religious writers interpret the unicorn. The myths refer to a beast with one horn that can only be tamed by a virgin, subsequently, with the rise of humanism, the unicorn also acquired more orthodox secular meanings, emblematic of chaste love and faithful marriage. The Throne Chair of Denmark is made of unicorn horns – almost certainly narwhal tusks, the same material was used for ceremonial cups because the unicorns horn continued to be believed to neutralize poison, following classical authors. The unicorn, tamable only by a woman, was well established in medieval lore by the time Marco Polo described them as scarcely smaller than elephants. They have the hair of a buffalo and feet like an elephants and they have a single large black horn in the middle of the forehead

Narwhal
–
The narwhal, or narwhale, is a medium-sized toothed whale that possesses a large tusk from a protruding canine tooth. It lives year-round in the Arctic waters around Greenland, Canada and it is one of two living species of whale in the Monodontidae family, along with the beluga whale. The narwhal males are distinguished by a long, straight, helical tusk, the narwhal was one of many species described by Carl Linnaeus in his publication Systema Naturae in 1758. Like the beluga, narwhals are medium-sized whales, for both sexes, excluding the males tusk, the total body size can range from 3.95 to 5.5 m, the males are slightly larger than the females. The average weight of an adult narwhal is 800 to 1,600 kg, at around 11 to 13 years old, the males become sexually mature, females become sexually mature at about 5 to 8 years old. Narwhals do not have a fin, and their neck vertebrae are jointed like those of other mammals, not fused as in dolphins. Found primarily in Canadian Arctic and Greenlandic and Russian waters, the narwhal is a uniquely specialized Arctic predator, in winter, it feeds on benthic prey, mostly flatfish, under dense pack ice. During the summer, narwhals mostly eat Arctic cod and Greenland halibut, each year, they migrate from bays into the ocean as summer comes. In the winter, the male narwhals occasionally dive up to 1,500 m in depth, with dives lasting up to 25 minutes, narwhals, like most toothed whales, communicate with clicks, whistles, and knocks. Narwhals can live up to 50 years and they are often killed by suffocation when the sea ice freezes over. Another cause of fatality, specifically among young whales, is starvation, the current population of the narwhal is about 75,000, so narwhals qualify for Near Threatened under the criterion of the International Union for Conservation of Nature. Narwhals have been harvested for over a thousand years by Inuit people in northern Canada and Greenland for meat and ivory, the narwhal was one of the many species originally described by Linnaeus in his Systema Naturae. The scientific name, Monodon monoceros, is derived from the Greek, the narwhal is most closely related to the beluga whale. Together, these two species comprise the extant members of the family Monodontidae, sometimes referred to as the white whales. The Monodontidae are distinguished by size, forehead melons, short snouts. Although the narwhal and the beluga are classified as separate genera, with one each, there is some evidence that they may, very rarely. The complete skull of a whale was discovered in West Greenland circa 1990. The white whales, dolphins and porpoises together comprise the superfamily Delphinoidea, fossil evidence shows that ancient white whales lived in tropical waters

Lemming
–
A lemming is a small rodent usually found in or near the Arctic in tundra biomes. They make up the subfamily Arvicolinae together with voles and muskrats, which part of the superfamily Muroidea, which also includes rats, mice, hamsters. Lemmings weigh from 30 to 110 g and are about 7 to 15 cm long and they generally have long, soft fur, and very short tails. They are herbivorous, feeding mostly on leaves and shoots, grasses, and sedges in particular, at times, they will eat grubs and larvae. Like other rodents, their incisors grow continuously, allowing them to exist on much tougher forage than would otherwise be possible, Lemmings do not hibernate through the harsh northern winter. They remain active, finding food by burrowing through the snow and they are solitary animals by nature, meeting only to mate and then going their separate ways, but like all rodents, they have a high reproductive rate and can breed rapidly when food is plentiful. It is not known why lemming populations fluctuate with such great variance roughly every four years, Lemming behavior and appearance are markedly different from those of other rodents, which are inconspicuously colored and try to conceal themselves from their predators. Lemmings, by contrast, are colored and behave aggressively towards predators. The lemming defense system is thought to be based on aposematism, misconceptions about lemmings go back many centuries. In the 1530s, geographer Zeigler of Strasbourg proposed the theory that the creatures fell out of the sky during stormy weather, Lemmings have become the subject of a widely popular misconception that they commit mass suicide when they migrate by jumping off cliffs. It is in not a mass suicide but the result of their migratory behavior. Driven by strong biological urges, some species of lemmings may migrate in groups when population density becomes too great. They can swim and may choose to cross a body of water in search of a new habitat, in such cases, many may drown if the body of water is so wide as to stretch their physical capabilities to the limit. This fact and the fluctuations in the population of Norwegian lemmings gave rise to the misconception. The misconception of lemming mass suicide is long-standing and has been popularized by a number of factors and it was well enough known to be mentioned in The Marching Morons, a 1951 short story by Cyril M. Kornbluth. In 1955, Disney Studio illustrator Carl Barks drew an Uncle Scrooge adventure comic with the title The Lemming with the Locket and this comic, which was inspired by a 1953 American Mercury article, showed massive numbers of lemmings jumping over Norwegian cliffs. Lemmings also appear in Arthur C, clarkes 1953 short story The Possessed, where their suicidal urges are attributed to the lingering consciousness of an alien group mind which had inhabited the species in the prehistoric past. In a 2010 board game by GMT games, Leaping Lemmings, players must maneuver lemmings across a board while avoiding hazards, the 1994 short film Lemming Aid portrayed a group of misfits attempting to save lemmings from mass suicide

Spontaneous generation
–
Spontaneous generation or anomalous generation is an obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. Typically, the idea was that certain forms such as fleas could arise from inanimate matter such as dust, a variant idea was that of equivocal generation, in which species such as tapeworms arose from unrelated living organisms, now understood to be their hosts. Doctrines supporting such processes of generation held that these processes are commonplace, such ideas are in contradiction to that of univocal generation, effectively exclusive reproduction from genetically related parent, generally of the same species. Today it is accepted to have been decisively dispelled during the 19th century by the experiments of Louis Pasteur. He expanded upon the investigations of predecessors, however, some experimental difficulties were still there and objections from persons holding the traditional views persisted. Many of these objections were dealt with by the work of John Tyndall. Pasteurs experiment is known to have refuted the theory of spontaneous generation in 1859. Disproof of the ideas of spontaneous generation is no longer controversial among professional biologists. John Desmond Bernal suggests that earlier theories such as spontaneous generation were based upon an explanation that life was created as a result of chance events. Crucial to this doctrine is the idea that life comes from non-life, with the conditions, an example would be the supposed seasonal generation of mice and other animals from the mud of the Nile. In the years following Louis Pasteurs experiment in 1862, the spontaneous generation fell into increasing disfavor. Experimentalists used a variety of terms for the study of the origin of life from non-living materials, heterogenesis was applied to once-living materials such as boiled broths, and Henry Charlton Bastian proposed the term archebiosis for life originating from inorganic materials. The two were lumped together as spontaneous generation, but disliking the term as sounding too random, for example, he claimed humans, in a different form, must have earlier been born mature like other animals, or they would not have survived. Anaximander also claimed that spontaneous generation continued to this day, with forms being produced directly from lifeless matter. Xenophanes traced the origin of man back to the period between the fluid stage of the earth and the formation of land. He too held to a generation of fully formed plants. Empedocles accepted the spontaneous generation of life, but held that there had to be trials of combinations of parts of animals that spontaneously arose, successful combinations formed the species we now see, unsuccessful forms failed to reproduce. Anaxagoras also adopted a terrestrial slime account, although he thought that the seeds of plants existed in the air from the beginning, Aristotle laid the foundations of Western natural philosophy

Bird-of-paradise
–
The birds-of-paradise are members of the family Paradisaeidae of the order Passeriformes. The majority of species are found in eastern Indonesia, Papua New Guinea, the family has 42 species in 15 genera. For the most part they are confined to dense rainforest habitat, the diet of all species is dominated by fruit and to a lesser extent arthropods. The birds-of-paradise have a variety of breeding systems, ranging from monogamy to lek-type polygamy, a number of species are threatened by hunting and habitat loss. For many years the birds-of-paradise were treated as being related to the bowerbirds. Today while both are treated as being part of the Australasian lineage Corvida, the two are now thought to be distantly related. The closest evolutionary relatives of the birds-of-paradise are the crow and jay family Corvidae, the monarch flycatchers Monarchidae, the second clade includes the parotias and the King of Saxony bird-of-paradise. The third clade provisionally contains a number of genera, Seleucidis, the Drepanornis sicklebills, Semioptera, Ptiloris and Lophorina, the fourth clade includes the Epimachus sicklebills, Paradigalla and the astrapias. The final clade includes the Cicinnurus and the Paradisaea birds-of-paradise, the exact limits of the family have been the subject of revision as well. The three species of satinbird were treated as a subfamily of the birds-of-paradise, Cnemophilinae, in spite of differences in the mouth, foot morphology and nesting habits they remained in the family until a 2000 study moved them to a separate family closer to the berrypeckers and longbills. The same study found that the Macgregors bird-of-paradise was actually a member of the large Australasian honeyeater family, in addition to these three species, a number of systematically enigmatic species and genera have been considered potential members of this family. The silktail of Fiji has been linked with the many times since its discovery. Recent molecular evidence now places the species with the fantails, hybrid birds-of-paradise may occur when individuals of different species, that look similar and have overlapping ranges, confuse each other for their own species and crossbreed. Birds-of-paradise are closely related to the corvids, birds-of-paradise range in size from the king bird-of-paradise at 50 g and 15 cm to the curl-crested manucode at 44 cm and 430 g. The male black sicklebill, with its tail, is the longest species at 110 cm. In most species, the tails of the males are larger and longer than the female, the wings are rounded and in some species structurally modified on the males in order to make sound. There is considerable variation in the family with regard to bill shape, bills may be long and decurved, as in the sicklebills and riflebirds, or small and slim like the Astrapias. As with body size bill size varies between the sexes, although species where the females have larger bills than the male are more common, plumage variation between the sexes is closely related to breeding system
