Barbara McClintock
–
Barbara McClintock was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock received her PhD in botany from Cornell University in 1927, there she started her career as the leader in the development of maize cytogenetics, the focus of her research for the rest of her life. From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize and she developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis—a mechanism by which exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits and she demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of genetic information. She was recognized among the best in the field, awarded prestigious fellowships, during the 1940s and 1950s, McClintock discovered transposition and used it to demonstrate that genes are responsible for turning physical characteristics on and off. She developed theories to explain the suppression and expression of genetic information from one generation of plants to the next. Due to skepticism of her research and its implications, she stopped publishing her data in 1953, later, she made an extensive study of the cytogenetics and ethnobotany of maize races from South America. Barbara McClintock was born Eleanor McClintock on June 16,1902 in Hartford, Connecticut, Thomas McClintock was the child of British immigrants, and Sara Handy, born Grace, descended from an old American Mayflower family. Marjorie, the oldest child, was born in October 1898, Mignon, the youngest, Malcolm Rider, was born 18 months after Barbara. As a young girl, her parents determined that Eleanor, a feminine and delicate name, was not appropriate for her, McClintock was an independent child beginning at a very young age, a trait she later identified as her capacity to be alone. She was described as a solitary and independent child and she was close to her father, but had a difficult relationship with her mother, tension that began when she was young. The McClintock family moved to Brooklyn in 1908 and McClintock completed her education there at Erasmus Hall High School. She discovered her love of science and reaffirmed her solitary personality during high school and she wanted to continue her studies at Cornell Universitys College of Agriculture. Her mother resisted sending McClintock to college, for fear that she would be unmarriageable, McClintock was almost prevented from starting college, but her father intervened just before registration began, and she matriculated at Cornell in 1919. McClintock began her studies at Cornells College of Agriculture in 1919, there, she participated in student government and was invited to join a sorority, though she soon realized that she preferred not to join formal organizations. Instead, McClintock took up music, specifically jazz and she studied botany, receiving a BSc in 1923. Her interest in genetics began when she took her first course in that field in 1921, the course was based on a similar one offered at Harvard University, and was taught by C. B

Nobel Prize
–
The Nobel Prize is a set of annual international awards bestowed in a number of categories by Swedish and Norwegian institutions in recognition of academic, cultural, or scientific advances. The will of the Swedish inventor Alfred Nobel established the prizes in 1895, the prizes in Chemistry, Literature, Peace, Physics, and Physiology or Medicine were first awarded in 1901. Medals made before 1980 were struck in 23 carat gold, between 1901 and 2016, the Nobel Prizes and the Prize in Economic Sciences were awarded 579 times to 911 people and organisations. With some receiving the Nobel Prize more than once, this makes a total of 23 organisations, the prize ceremonies take place annually in Stockholm, Sweden. Each recipient, or laureate, receives a medal, a diploma. The Nobel Prize is widely regarded as the most prestigious award available in the fields of literature, medicine, physics, chemistry, peace, and economics. The prize is not awarded posthumously, however, if a person is awarded a prize and dies before receiving it, though the average number of laureates per prize increased substantially during the 20th century, a prize may not be shared among more than three people. Alfred Nobel was born on 21 October 1833 in Stockholm, Sweden and he was a chemist, engineer, and inventor. In 1894, Nobel purchased the Bofors iron and steel mill and this invention was a precursor to many smokeless military explosives, especially the British smokeless powder cordite. As a consequence of his patent claims, Nobel was eventually involved in a patent infringement lawsuit over cordite, Nobel amassed a fortune during his lifetime, with most of his wealth from his 355 inventions, of which dynamite is the most famous. In 1888, Nobel was astonished to read his own obituary, titled The merchant of death is dead, as it was Alfreds brother Ludvig who had died, the obituary was eight years premature. The article disconcerted Nobel and made him apprehensive about how he would be remembered and this inspired him to change his will. On 10 December 1896, Alfred Nobel died in his villa in San Remo, Italy, Nobel wrote several wills during his lifetime. He composed the last over a year before he died, signing it at the Swedish–Norwegian Club in Paris on 27 November 1895, Nobel bequeathed 94% of his total assets,31 million SEK, to establish the five Nobel Prizes. Because of skepticism surrounding the will, it was not until 26 April 1897 that it was approved by the Storting in Norway. The executors of Nobels will, Ragnar Sohlman and Rudolf Lilljequist, formed the Nobel Foundation to take care of Nobels fortune, Nobels instructions named a Norwegian Nobel Committee to award the Peace Prize, the members of whom were appointed shortly after the will was approved in April 1897. Soon thereafter, the other prize-awarding organisations were designated or established and these were Karolinska Institutet on 7 June, the Swedish Academy on 9 June, and the Royal Swedish Academy of Sciences on 11 June. The Nobel Foundation reached an agreement on guidelines for how the prizes should be awarded, and, in 1900, in 1905, the personal union between Sweden and Norway was dissolved

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

College
–
College is an educational institution or a constituent part of one. A college may be a tertiary educational institution, a part of a collegiate or federal university. In ancient Rome a collegium was a club or society, a group of living together under a common set of rules. Aside from the educational context - nowadays the most common use of college - there are various other meanings also derived from the original Latin term. In the United States, college can be a synonym for university, in Singapore and India, this is known as a junior college. The municipal government of the city of Paris uses the sixth form college as the English name for a lycée. In some national education systems, secondary schools may be called colleges or have college as part of their title, in Australia the term college is applied to any private or independent primary and, especially, secondary school as distinct from a state school. Melbourne Grammar School, Cranbrook School, Sydney and The Kings School, there has also been a recent trend to rename or create government secondary schools as colleges. In the state of Victoria, some high schools are referred to as secondary colleges. Interestingly, the pre-eminent government secondary school for boys in Melbourne is still named Melbourne High School, in Western Australia, South Australia and the Northern Territory, college is used in the name of all state high schools built since the late 1990s, and also some older ones. In New South Wales, some schools, especially multi-campus schools resulting from mergers, are known as secondary colleges. In Queensland some newer schools which accept primary and high school students are styled state college, in Tasmania and the Australian Capital Territory, college refers to the final two years of high school, and the institutions which provide this. In this context, college is an independent of the other years of high school. Here, the expression is a version of matriculation college. This is because these schools have traditionally focused on academic, rather than vocational, subjects. Some private secondary schools choose to use the college in their names nevertheless. Some secondary schools elsewhere in the country, particularly ones within the school system. In New Zealand the word normally refers to a secondary school for ages 13 to 17

Teacher
–
A teacher is a person who helps others to acquire knowledge, competences or values. Informally the role of teacher may be taken on by anyone, in some countries, teaching young people of school age may be carried out in an informal setting, such as within the family, rather than in a formal setting such as a school or college. Some other professions may involve a significant amount of teaching, in most countries, formal teaching is usually carried out by paid professional teachers. This article focuses on those who are employed, as their role, to teach others in a formal education context. A teachers role may vary among cultures, Teachers may provide instruction in literacy and numeracy, craftsmanship or vocational training, the arts, religion, civics, community roles, or life skills. Formal teaching tasks include preparing lessons according to agreed curricula, giving lessons, a teachers professional duties may extend beyond formal teaching. In some education systems, teachers may have responsibility for student discipline, Teaching is a highly complex activity. This is in part because teaching is a practice, that takes place in a specific context. Factors that influence what is expected of teachers include history and tradition, social views about the purpose of education, so the competences required by a teacher are affected by the different ways in which the role is understood around the world. Broadly, there seem to be four models, the teacher as manager of instruction, the teacher as caring person, the teacher as expert learner, some evidence-based international discussions have tried to reach such a common understanding. Scholarly consensus is emerging that what is required of teachers can be grouped under three headings, knowledge craft skills and dispositions and it has been found that teachers who showed enthusiasm towards the course materials and students can create a positive learning experience. These teachers do not teach by rote but attempt to find new invigoration for the materials on a daily basis. One of the challenges facing teachers is that they may have covered a curriculum until they begin to feel bored with the subject. Students who had enthusiastic teachers tend to rate them higher than teachers who didnt show much enthusiasm for the course materials, Teachers that exhibit enthusiasm can lead to students who are more likely to be engaged, interested, energetic, and curious about learning the subject matter. Recent research has found a correlation between teacher enthusiasm and students intrinsic motivation to learn and vitality in the classroom, students who experienced a very enthusiastic teacher were more likely to read lecture material outside of the classroom. There are various mechanisms by which teacher enthusiasm may facilitate higher levels of intrinsic motivation, teacher enthusiasm may contribute to a classroom atmosphere of energy and enthusiasm which feeds student interest and excitement in learning the subject matter. Enthusiastic teachers may also lead to becoming more self-determined in their own learning process. The concept of mere exposure indicates that the teachers enthusiasm may contribute to the expectations about intrinsic motivation in the context of learning

Communication
–
Communication is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules. The main steps inherent to all communication are, The forming of communicative motivation or reason, transmission of the encoded message as a sequence of signals using a specific channel or medium. Noise sources such as forces and in some cases human activity begin influencing the quality of signals propagating from the sender to one or more receivers. Reception of signals and reassemblying of the message from a sequence of received signals. Decoding of the encoded message. Interpretation and making sense of the original message. The channel of communication can be visual, auditory, tactile and haptic, olfactory, electromagnetic, human communication is unique for its extensive use of abstract language. Development of civilization has been linked with progress in telecommunication. Nonverbal communication describes the process of conveying information in the form of non-linguistic representations, examples of nonverbal communication include haptic communication, chronemic communication, gestures, body language, facial expressions, eye contact, and how one dresses. Nonverbal communication also relates to intent of a message, examples of intent are voluntary, intentional movements like shaking a hand or winking, as well as involuntary, such as sweating. Speech also contains nonverbal elements known as paralanguage, e. g. rhythm, intonation, tempo and it affects communication most at the subconscious level and establishes trust. Likewise, written texts include nonverbal elements such as handwriting style, spatial arrangement of words, Nonverbal communication demonstrates one of Wazlawicks laws, you cannot not communicate. Once proximity has formed awareness, living creatures begin interpreting any signals received, Nonverbal cues are heavily relied on to express communication and to interpret others’ communication and can replace or substitute verbal messages. There are several reasons as to why non-verbal communication plays a role in communication. Written communication can also have non-verbal attributes, e-mails and web chats allow individual’s the option to change text font colours, stationary, emoticons, and capitalization in order to capture non-verbal cues into a verbal medium. Many different non-verbal channels are engaged at the time in communication acts. “Non-verbal behaviours may form a language system. ”Smiling, crying, pointing, caressing. Such non-verbal signals allow the most basic form of communication when verbal communication is not effective due to language barriers, Verbal communication is the spoken or written conveyance of a message

Library
–
A library is a collection of sources of information and similar resources, made accessible to a defined community for reference or borrowing. It provides physical or digital access to material, and may be a building or room, or a virtual space. Libraries range in size from a few shelves of books to several million items, in Latin and Greek, the idea of a bookcase is represented by Bibliotheca and Bibliothēkē, derivatives of these mean library in many modern languages, e. g. French bibliothèque. The first libraries consisted of archives of the earliest form of clay tablets in cuneiform script discovered in Sumer. Private or personal libraries made up of books appeared in classical Greece in the 5th century BC. In the 6th century, at the close of the Classical period. A library is organized for use and maintained by a body, an institution. In addition to providing materials, libraries also provide the services of librarians who are experts at finding and organizing information, Libraries often provide quiet areas for studying, and they also often offer common areas to facilitate group study and collaboration. Libraries often provide facilities for access to their electronic resources. Modern libraries are increasingly being redefined as places to get unrestricted access to information in many formats, the first libraries consisted of archives of the earliest form of writing—the clay tablets in cuneiform script discovered in temple rooms in Sumer, some dating back to 2600 BC. These archives, which consisted of the records of commercial transactions or inventories, mark the end of prehistory. Things were much the same in the government and temple records on papyrus of Ancient Egypt, the earliest discovered private archives were kept at Ugarit, besides correspondence and inventories, texts of myths may have been standardized practice-texts for teaching new scribes. There is also evidence of libraries at Nippur about 1900 BC, philosopher Laozi was keeper of books in the earliest library in China, which belonged to the Imperial Zhou dynasty. Also, evidence of catalogues found in some destroyed ancient libraries illustrates the presence of librarians, the Library of Alexandria, in Egypt, was the largest and most significant great library of the ancient world. It flourished under the patronage of the Ptolemaic dynasty and functioned as a center of scholarship from its construction in the 3rd century BC until the Roman conquest of Egypt in 30 BC. The library was conceived and opened either during the reign of Ptolemy I Soter or during the reign of his son Ptolemy II, an early organization system was in effect at Alexandria. The Library of Celsus in Ephesus, Anatolia, now part of Selçuk, Turkey was built in honor of the Roman Senator Tiberius Julius Celsus Polemaeanus by Celsus’ son, the library was built to store 12,000 scrolls and to serve as a monumental tomb for Celsus. Private or personal libraries made up of books appeared in classical Greece in the 5th century BC

Museum
–
Most large museums are located in major cities throughout the world and more local ones exist in smaller cities, towns and even the countryside. Museums have varying aims, ranging from serving researchers and specialists to serving the general public, the goal of serving researchers is increasingly shifting to serving the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, the city with the largest number of museums is Mexico City with over 128 museums. According to The World Museum Community, there are more than 55,000 museums in 202 countries, the English museum comes from the Latin word, and is pluralized as museums. The first museum/library is considered to be the one of Plato in Athens, however, Pausanias gives another place called Museum, namely a small hill in Classical Athens opposite to the Akropolis. The hill was called Mouseion after Mousaious, a man who used to sing on the hill, the purpose of modern museums is to collect, preserve, interpret, and display items of artistic, cultural, or scientific significance for the education of the public. The purpose can also depend on ones point of view, to a family looking for entertainment on a Sunday afternoon, a trip to a local history museum or large city art museum could be a fun, and enlightening way to spend the day. To city leaders, a healthy museum community can be seen as a gauge of the health of a city. To a museum professional, a museum might be seen as a way to educate the public about the museums mission, Museums are, above all, storehouses of knowledge. In 1829, James Smithsons bequest, that would fund the Smithsonian Institution, stated he wanted to establish an institution for the increase, Museums of natural history in the late 19th century exemplified the Victorian desire for consumption and for order. Gathering all examples of classification of a field of knowledge for research. As American colleges grew in the 19th century, they developed their own natural history collections for the use of their students, while many large museums, such as the Smithsonian Institution, are still respected as research centers, research is no longer a main purpose of most museums. While there is a debate about the purposes of interpretation of a museums collection, there has been a consistent mission to protect. Much care, expertise, and expense is invested in efforts to retard decomposition in aging documents, artifacts, artworks. All museums display objects that are important to a culture, as historian Steven Conn writes, To see the thing itself, with ones own eyes and in a public place, surrounded by other people having some version of the same experience can be enchanting. Museum purposes vary from institution to institution, some favor education over conservation, or vice versa. For example, in the 1970s, the Canada Science and Technology Museum favored education over preservation of their objects and they displayed objects as well as their functions. One exhibit featured a printing press that a staff member used for visitors to create museum memorabilia

Education
–
Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, Education frequently takes place under the guidance of educators, but learners may also educate themselves. Education can take place in formal or informal settings and any experience that has an effect on the way one thinks, feels. The methodology of teaching is called pedagogy, in most regions education is compulsory up to a certain age. Etymologically, the education is derived from the Latin ēducātiō from ēducō which is related to the homonym ēdūcō from ē-. Education began in prehistory, as trained the young in the knowledge. In pre-literate societies this was achieved orally and through imitation, story-telling passed knowledge, values, and skills from one generation to the next. As cultures began to extend their knowledge beyond skills that could be learned through imitation. Schools existed in Egypt at the time of the Middle Kingdom, plato founded the Academy in Athens, the first institution of higher learning in Europe. The city of Alexandria in Egypt, established in 330 BCE, there, the great Library of Alexandria was built in the 3rd century BCE. European civilizations suffered a collapse of literacy and organization following the fall of Rome in CE476, after the Fall of Rome, the Catholic Church became the sole preserver of literate scholarship in Western Europe. The church established cathedral schools in the Early Middle Ages as centres of advanced education, some of these establishments ultimately evolved into medieval universities and forebears of many of Europes modern universities. During the High Middle Ages, Chartres Cathedral operated the famous, founded in 1088, the University of Bologne is considered the first, and the oldest continually operating university. The Renaissance in Europe ushered in a new age of scientific and intellectual inquiry and appreciation of ancient Greek, around 1450, Johannes Gutenberg developed a printing press, which allowed works of literature to spread more quickly. The European Age of Empires saw European ideas of education in philosophy, religion, arts, the Enlightenment saw the emergence of a more secular educational outlook in Europe. In most countries today, full-time education, whether at school or otherwise, is compulsory for all children up to a certain age, formal education occurs in a structured environment whose explicit purpose is teaching students. Usually, formal education takes place in a environment with classrooms of multiple students learning together with a trained, certified teacher of the subject. Most school systems are designed around a set of values or ideals that govern all educational choices in that system, such choices include curriculum, organizational models, design of the physical learning spaces, student-teacher interactions, methods of assessment, class size, educational activities, and more

Multimedia
–
Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content. Multimedia contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material, Multimedia devices are electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed media in art, for example. The term rich media is synonymous with interactive multimedia, the term multimedia was coined by singer and artist Bob Goldstein to promote the July 1966 opening of his LightWorks at LOursin show at Southampton, Long Island. Goldstein was perhaps aware of an American artist named Dick Higgins, two years later, in 1968, the term multimedia was re-appropriated to describe the work of a political consultant, David Sawyer, the husband of Iris Sawyer—one of Goldsteins producers at LOursin. In the intervening forty years, the word has taken on different meanings, in the late 1970s, the term referred to presentations consisting of multi-projector slide shows timed to an audio track. However, by the 1990s multimedia took on its current meaning, in the 1993 first edition of Multimedia, Making It Work, Tay Vaughan declared Multimedia is any combination of text, graphic art, sound, animation, and video that is delivered by computer. When you allow the user – the viewer of the project – to control what, when you provide a structure of linked elements through which the user can navigate, interactive multimedia becomes hypermedia. The German language society Gesellschaft für deutsche Sprache recognized the words significance, the institute summed up its rationale by stating has become a central word in the wonderful new media world. In common usage, multimedia refers to an electronically delivered combination of media including video, still images, audio, much of the content on the web today falls within this definition as understood by millions. That era saw also a boost in the production of educational multimedia CD-ROMs, the term video, if not used exclusively to describe motion photography, is ambiguous in multimedia terminology. Video is often used to describe the format, delivery format. Multiple forms of content are often not considered modern forms of presentation such as audio or video. Likewise, single forms of content with single methods of information processing are often called multimedia. Performing arts may also be considered multimedia considering that performers and props are multiple forms of content and media. Multimedia presentations may be viewed by person on stage, projected, transmitted, a broadcast may be a live or recorded multimedia presentation. Broadcasts and recordings can be analog or digital electronic media technology. Digital online multimedia may be downloaded or streamed, streaming multimedia may be live or on-demand

William Hogarth
–
William Hogarth FRSA was an English painter, printmaker, pictorial satirist, social critic, and editorial cartoonist who has been credited with pioneering western sequential art. His work ranged from realistic portraiture to comic series of pictures called modern moral subjects. Knowledge of his work is so pervasive that satirical political illustrations in this style are referred to as Hogarthian. William Hogarth was born at Bartholomew Close in London to Richard Hogarth, a poor Latin school teacher and textbook writer, in his youth he was apprenticed to the engraver Ellis Gamble in Leicester Fields, where he learned to engrave trade cards and similar products. Young Hogarth also took a lively interest in the life of the metropolis and the London fairs. Around the same time, his father, who had opened an unsuccessful Latin-speaking coffee house at St Johns Gate, was imprisoned for debt in Fleet Prison for five years, Hogarth never spoke of his fathers imprisonment. Hogarth became a member of the Rose and Crown Club, with Peter Tillemans, George Vertue, Michael Dahl, by April 1720, Hogarth was an engraver in his own right, at first engraving coats of arms, shop bills, and designing plates for booksellers. In 1727, he was hired by Joshua Morris, a tapestry worker, Morris heard that he was an engraver, and no painter, and consequently declined the work when completed. Hogarth accordingly sued him for the money in the Westminster Court, in 1757 he was appointed Serjeant Painter to the King. In the bottom corner, he shows Protestant, Catholic, and Jewish figures gambling, while in the middle there is a huge machine, like a merry-go-round. At the top is a goat, written below which is Whol Ride, Other early works include The Lottery, The Mystery of Masonry brought to Light by the Gormogons, A Just View of the British Stage, some book illustrations, and the small print Masquerades and Operas. He continued that theme in 1727, with the Large Masquerade Ticket, in 1726 Hogarth prepared twelve large engravings for Samuel Butlers Hudibras. These he himself valued highly, and they are among his best book illustrations, in the following years he turned his attention to the production of small conversation pieces. One of his real low-life and real-life subjects was Sarah Malcolm who he sketched two days before her execution and he might also have printed Burlington Gate, evoked by Alexander Popes Epistle to Lord Burlington, and defending Lord Chandos, who is therein satirized. This print gave great offence, and was suppressed, however, modern authorities such as Ronald Paulson no longer attribute it to Hogarth. In 1731 Hogarth completed the earliest of his series of moral works, the collection of six scenes was entitled A Harlots Progress and appeared first as paintings before being published as engravings. The inaugural series was a success and was followed in 1735 by the sequel A Rakes Progress. The original paintings of A Harlots Progress were destroyed in the fire at Fonthill House in 1755, while A Rakes Progress is displayed in the room at Sir John Soanes Museum, London

Engraving
–
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it. Wood engraving is a form of printing and is not covered in this article. Engraving was an important method of producing images on paper in artistic printmaking, in mapmaking. Other terms often used for printed engravings are copper engraving, copper-plate engraving or line engraving, hand engraving is a term sometimes used for engraving objects other than printing plates, to inscribe or decorate jewellery, firearms, trophies, knives and other fine metal goods. Traditional engravings in printmaking are also engraved, using just the same techniques to make the lines in the plate. Each graver is different and has its own use, engravers use a hardened steel tool called a burin, or graver, to cut the design into the surface, most traditionally a copper plate. Modern professional engravers can engrave with a resolution of up to 40 lines per mm in high grade work creating game scenes, dies used in mass production of molded parts are sometimes hand engraved to add special touches or certain information such as part numbers. In addition to engraving, there are engraving machines that require less human finesse and are not directly controlled by hand. They are usually used for lettering, using a pantographic system, there are versions for the insides of rings and also the outsides of larger pieces. Such machines are used for inscriptions on rings, lockets. Gravers come in a variety of shapes and sizes that yield different line types, the burin produces a unique and recognizable quality of line that is characterized by its steady, deliberate appearance and clean edges. The angle tint tool has a curved tip that is commonly used in printmaking. Florentine liners are flat-bottomed tools with multiple lines incised into them, ring gravers are made with particular shapes that are used by jewelry engravers in order to cut inscriptions inside rings. Flat gravers are used for work on letters, as well as wriggle cuts on most musical instrument engraving work, remove background. Knife gravers are for line engraving and very deep cuts, round gravers, and flat gravers with a radius, are commonly used on silver to create bright cuts, as well as other hard-to-cut metals such as nickel and steel. Square or V-point gravers are typically square or elongated diamond-shaped and used for cutting straight lines, V-point can be anywhere from 60 to 130 degrees, depending on purpose and effect. These gravers have very small cutting points, other tools such as mezzotint rockers, roulets and burnishers are used for texturing effects. Burnishing tools can also be used for stone setting techniques
