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

Melancholia
–
Melancholy was one of the four temperaments matching the four humours. In the 19th century, melancholia could be physical as well as mental, the name melancholia comes from the old medical belief of the four humours, disease or ailment being caused by an imbalance in one or other of the four basic bodily liquids, or humours. Personality types were similarly determined by the dominant humor in a particular person, in astrology it showed the influence of Saturn, hence the related adjective saturnine. Melancholia was described as a disease with particular mental and physical symptoms in the 5th and 4th centuries BC. Hippocrates, in his Aphorisms, characterized all fears and despondencies, when a patient could not be cured of the disease it was thought that the melancholia was a result of demonic possession. In his study of French and Burgundian courtly culture, Johan Huizinga noted that at the close of the Middle Ages, a sombre melancholy weighs on peoples souls. Among those of his contemporaries so characterised by Vasari were Pontormo and Parmigianino, but he not use the term of Michelangelo. A famous allegorical engraving by Albrecht Dürer is entitled Melencolia I and this engraving has been interpreted as portraying melancholia as the state of waiting for inspiration to strike, and not necessarily as a depressive affliction. Amongst other allegorical symbols, the picture includes a magic square, the image in turn inspired a passage in The City of Dreadful Night by James Thomson, and, a few years later, a sonnet by Edward Dowden. The most extended treatment of melancholia comes from Robert Burton, whose The Anatomy of Melancholy treats the subject from both a literary and a medical perspective, Burton wrote in the 17th century that music and dance were critical in treating mental illness, especially melancholia. Ismenias the Theban, Chiron the centaur, is said to have cured this and many other diseases by music alone, as now they do those, saith Bodine, during the later 16th and early 17th centuries, a curious cultural and literary cult of melancholia arose in England. Another major English author who made extensive expression upon being of a disposition is Sir Thomas Browne in his Religio Medici. Night-Thoughts, a poem in blank verse by Edward Young was published in nine parts between 1742 and 1745, and hugely popular in several languages. It had a influence on early Romantics in England, France. William Blake was commissioned to illustrate a later edition and these portraits were often set out of doors where Nature provides the most suitable background for spiritual contemplation or in a gloomy interior. In music, the cult of melancholia is associated with John Dowland, whose motto was Semper Dowland. The melancholy man, known to contemporaries as a malcontent, is epitomized by Shakespeares Prince Hamlet, the medieval condition of acedia and the Romantic Weltschmerz were similar concepts, most likely to affect the intellectual. It has been identified in medical writings from antiquity and was best characterized in the 19th Century, in the 20th Century, with the interest in psychoanalytic writing, major depression became the principal class in psychiatric classifications

Psychology
–
Psychology is the science of behavior and mind, embracing all aspects of conscious and unconscious experience as well as thought. It is a discipline and a social science which seeks to understand individuals and groups by establishing general principles. In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioral, Psychologists explore behavior and mental processes, including perception, cognition, attention, emotion, intelligence, phenomenology, motivation, brain functioning, and personality. This extends to interaction between people, such as relationships, including psychological resilience, family resilience, and other areas. Psychologists of diverse orientations also consider the unconscious mind, Psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. Psychology has been described as a hub science, with psychological findings linking to research and perspectives from the sciences, natural sciences, medicine, humanities. By many accounts psychology ultimately aims to benefit society, the majority of psychologists are involved in some kind of therapeutic role, practicing in clinical, counseling, or school settings. Many do scientific research on a range of topics related to mental processes and behavior. The word psychology derives from Greek roots meaning study of the psyche, the Latin word psychologia was first used by the Croatian humanist and Latinist Marko Marulić in his book, Psichiologia de ratione animae humanae in the late 15th century or early 16th century. In 1890, William James defined psychology as the science of mental life and this definition enjoyed widespread currency for decades. Also since James defined it, the more strongly connotes techniques of scientific experimentation. Folk psychology refers to the understanding of people, as contrasted with that of psychology professionals. The ancient civilizations of Egypt, Greece, China, India, historians note that Greek philosophers, including Thales, Plato, and Aristotle, addressed the workings of the mind. As early as the 4th century BC, Greek physician Hippocrates theorized that mental disorders had physical rather than supernatural causes, in China, psychological understanding grew from the philosophical works of Laozi and Confucius, and later from the doctrines of Buddhism. This body of knowledge involves insights drawn from introspection and observation and it frames the universe as a division of, and interaction between, physical reality and mental reality, with an emphasis on purifying the mind in order to increase virtue and power. Chinese scholarship focused on the advanced in the Qing Dynasty with the work of Western-educated Fang Yizhi, Liu Zhi. Distinctions in types of awareness appear in the ancient thought of India, a central idea of the Upanishads is the distinction between a persons transient mundane self and their eternal unchanging soul. Divergent Hindu doctrines, and Buddhism, have challenged this hierarchy of selves, yoga is a range of techniques used in pursuit of this goal

Astronomy
–
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets, while the phenomena include supernovae explosions, gamma ray bursts, more generally, all astronomical phenomena that originate outside Earths atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole, Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, during the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the results and observations being used to confirm theoretical results. Astronomy is one of the few sciences where amateurs can play an active role, especially in the discovery. Amateur astronomers have made and contributed to many important astronomical discoveries, Astronomy means law of the stars. Astronomy should not be confused with astrology, the system which claims that human affairs are correlated with the positions of celestial objects. Although the two share a common origin, they are now entirely distinct. Generally, either the term astronomy or astrophysics may be used to refer to this subject, however, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics. Few fields, such as astrometry, are purely astronomy rather than also astrophysics, some titles of the leading scientific journals in this field includeThe Astronomical Journal, The Astrophysical Journal and Astronomy and Astrophysics. In early times, astronomy only comprised the observation and predictions of the motions of objects visible to the naked eye, in some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye, most of early astronomy actually consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, and the nature of the Sun, Moon, the Earth was believed to be the center of the Universe with the Sun, the Moon and the stars rotating around it. This is known as the model of the Universe, or the Ptolemaic system. The Babylonians discovered that lunar eclipses recurred in a cycle known as a saros

Meteorology
–
Meteorology is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics, with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century, the 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data, Meteorological phenomena are observable weather events that are explained by the science of meteorology. Different spatial scales are used to describe and predict weather on local, regional, Meteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology compose the interdisciplinary field of hydrometeorology, the interactions between Earths atmosphere and its oceans are part of a coupled ocean-atmosphere system. Meteorology has application in diverse fields such as the military, energy production, transport, agriculture. The word meteorology is from Greek μετέωρος metéōros lofty, high and -λογία -logia -logy, varāhamihiras classical work Brihatsamhita, written about 500 AD, provides clear evidence that a deep knowledge of atmospheric processes existed even in those times. In 350 BC, Aristotle wrote Meteorology, Aristotle is considered the founder of meteorology. One of the most impressive achievements described in the Meteorology is the description of what is now known as the hydrologic cycle and they are all called swooping bolts because they swoop down upon the Earth. Lightning is sometimes smoky, and is then called smoldering lightning, sometimes it darts quickly along, at other times, it travels in crooked lines, and is called forked lightning. When it swoops down upon some object it is called swooping lightning, the Greek scientist Theophrastus compiled a book on weather forecasting, called the Book of Signs. The work of Theophrastus remained a dominant influence in the study of weather, in 25 AD, Pomponius Mela, a geographer for the Roman Empire, formalized the climatic zone system. According to Toufic Fahd, around the 9th century, Al-Dinawari wrote the Kitab al-Nabat, ptolemy wrote on the atmospheric refraction of light in the context of astronomical observations. St. Roger Bacon was the first to calculate the size of the rainbow. He stated that a rainbow summit can not appear higher than 42 degrees above the horizon, in the late 13th century and early 14th century, Kamāl al-Dīn al-Fārisī and Theodoric of Freiberg were the first to give the correct explanations for the primary rainbow phenomenon. Theoderic went further and also explained the secondary rainbow, in 1716, Edmund Halley suggested that aurorae are caused by magnetic effluvia moving along the Earths magnetic field lines. In 1441, King Sejongs son, Prince Munjong, invented the first standardized rain gauge and these were sent throughout the Joseon Dynasty of Korea as an official tool to assess land taxes based upon a farmers potential harvest. In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and was known as the first anemometer, in 1607, Galileo Galilei constructed a thermoscope

Theology
–
Theology is the critical study of the nature of the divine. It is taught as a discipline, typically in universities, seminaries. Augustine of Hippo defined the Latin equivalent, theologia, as reasoning or discussion concerning the Deity, the term can, however, be used for a variety of different disciplines or fields of study. Theologians use various forms of analysis and argument to help understand, explain, test, critique, the English equivalent theology had evolved by 1362. Greek theologia was used with the discourse on god in the fourth century BC by Plato in The Republic, Book ii. Drawing on Greek Stoic sources, the Latin writer Varro distinguished three forms of discourse, mythical, rational and civil. Theologos, closely related to theologia, appears once in some manuscripts, in the heading to the book of Revelation, apokalypsis ioannoy toy theologoy. The Latin author Boethius, writing in the early 6th century, used theologia to denote a subdivision of philosophy as a subject of study, dealing with the motionless. Boethius definition influenced medieval Latin usage, Theology can also now be used in a derived sense to mean a system of theoretical principles, an ideology. They suggest the term is appropriate in religious contexts that are organized differently. Kalam. does not hold the place in Muslim thought that theology does in Christianity. To find an equivalent for theology in the Christian sense it is necessary to have recourse to several disciplines, and to the usul al-fiqh as much as to kalam. Jose Ignacio Cabezon, who argues that the use of theology is appropriate, can only do so, he says, I take theology not to be restricted to its etymological meaning. In that latter sense, Buddhism is of course atheological, rejecting as it does the notion of God, within Hindu philosophy, there is a solid and ancient tradition of philosophical speculation on the nature of the universe, of God and of the Atman. The Sanskrit word for the schools of Hindu philosophy is Darshana. Nevertheless, Jewish theology historically has been active and highly significant for Christian. It is sometimes claimed, however, that the Jewish analogue of Christian theological discussion would more properly be Rabbinical discussion of Jewish law, the history of the study of theology in institutions of higher education is as old as the history of such institutions themselves. Modern Western universities evolved from the institutions and cathedral schools of Western Europe during the High Middle Ages

Astrology
–
Astrology is the study of the movements and relative positions of celestial objects as a means for divining information about human affairs and terrestrial events. Throughout most of its history astrology was considered a tradition and was common in academic circles, often in close relation with astronomy, alchemy, meteorology. It was present in political circles, and is mentioned in works of literature, from Dante Alighieri and Geoffrey Chaucer to William Shakespeare, Lope de Vega. Astrology thus lost its academic and theoretical standing, and common belief in it has largely declined, Astrology is now recognized to be pseudoscience. The word astrology comes from the early Latin word astrologia, which derives from the Greek ἀστρολογία—from ἄστρον astron, astrologia later passed into meaning star-divination with astronomia used for the scientific term. Many cultures have attached importance to astronomical events, and the Indians, Chinese, the majority of professional astrologers rely on such systems. Astrology has been dated to at least the 2nd millennium BCE, with roots in systems used to predict seasonal shifts. A form of astrology was practised in the first dynasty of Mesopotamia, Chinese astrology was elaborated in the Zhou dynasty. Hellenistic astrology after 332 BCE mixed Babylonian astrology with Egyptian Decanic astrology in Alexandria, Alexander the Greats conquest of Asia allowed astrology to spread to Ancient Greece and Rome. In Rome, astrology was associated with Chaldean wisdom, after the conquest of Alexandria in the 7th century, astrology was taken up by Islamic scholars, and Hellenistic texts were translated into Arabic and Persian. In the 12th century, Arabic texts were imported to Europe, major astronomers including Tycho Brahe, Johannes Kepler and Galileo practised as court astrologers. Astrological references appear in literature in the works of such as Dante Alighieri and Geoffrey Chaucer. Throughout most of its history, astrology was considered a scholarly tradition and it was accepted in political and academic contexts, and was connected with other studies, such as astronomy, alchemy, meteorology, and medicine. At the end of the 17th century, new concepts in astronomy. Astrology thus lost its academic and theoretical standing, and common belief in astrology has largely declined, Astrology, in its broadest sense, is the search for meaning in the sky. This was a first step towards recording the Moons influence upon tides and rivers, by the 3rd millennium BCE, civilisations had sophisticated awareness of celestial cycles, and may have oriented temples in alignment with heliacal risings of the stars. Scattered evidence suggests that the oldest known references are copies of texts made in the ancient world. The Venus tablet of Ammisaduqa thought to be compiled in Babylon around 1700 BCE, a scroll documenting an early use of electional astrology is doubtfully ascribed to the reign of the Sumerian ruler Gudea of Lagash

Aristotle
–
Aristotle was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, at seventeen or eighteen years of age, he joined Platos Academy in Athens and remained there until the age of thirty-seven. Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, teaching Alexander the Great gave Aristotle many opportunities and an abundance of supplies. He established a library in the Lyceum which aided in the production of many of his hundreds of books and he believed all peoples concepts and all of their knowledge was ultimately based on perception. Aristotles views on natural sciences represent the groundwork underlying many of his works, Aristotles views on physical science profoundly shaped medieval scholarship. Their influence extended from Late Antiquity and the Early Middle Ages into the Renaissance, some of Aristotles zoological observations, such as on the hectocotyl arm of the octopus, were not confirmed or refuted until the 19th century. His works contain the earliest known study of logic, which was incorporated in the late 19th century into modern formal logic. Aristotle was well known among medieval Muslim intellectuals and revered as The First Teacher and his ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotles philosophy continue to be the object of academic study today. Though Aristotle wrote many elegant treatises and dialogues – Cicero described his style as a river of gold – it is thought that only around a third of his original output has survived. Aristotle, whose means the best purpose, was born in 384 BC in Stagira, Chalcidice. His father Nicomachus was the physician to King Amyntas of Macedon. Aristotle was orphaned at a young age, although there is little information on Aristotles childhood, he probably spent some time within the Macedonian palace, making his first connections with the Macedonian monarchy. At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Platos Academy and he remained there for nearly twenty years before leaving Athens in 348/47 BC. Aristotle then accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor, there, he traveled with Theophrastus to the island of Lesbos, where together they researched the botany and zoology of the island. Aristotle married Pythias, either Hermiass adoptive daughter or niece and she bore him a daughter, whom they also named Pythias. Soon after Hermias death, Aristotle was invited by Philip II of Macedon to become the tutor to his son Alexander in 343 BC, Aristotle was appointed as the head of the royal academy of Macedon. During that time he gave not only to Alexander

Galen
–
Aelius Galenus or Claudius Galenus, often Anglicized as Galen and better known as Galen of Pergamon, was a prominent Greek physician, surgeon and philosopher in the Roman Empire. The son of Aelius Nicon, an architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician. Galens understanding of anatomy and medicine was influenced by the then-current theory of humorism. His theories dominated and influenced Western medical science for more than 1,300 years, Medical students continued to study Galens writings until well into the 19th century. Galen saw himself as both a physician and a philosopher, as he wrote in his treatise entitled That the Best Physician is Also a Philosopher. Many of his works have been preserved and/or translated from the original Greek, although many were destroyed, although there is some debate over the date of his death, he was no younger than seventy when he died. In medieval Europe, Galens writings on anatomy became the mainstay of the medieval university curriculum. Some of Galens ideas were incorrect, he did not dissect a human body, Galens original Greek texts gained renewed prominence during the early modern period. In the 1530s, Belgian anatomist and physician Andreas Vesalius took on a project to many of Galens Greek texts into Latin. Vesaliuss most famous work, De humani corporis fabrica, was influenced by Galenic writing. Galens name Γαληνός, Galēnos comes from the adjective γαληνός, calm, Galen describes his early life in On the affections of the mind. Galen describes his father as an amiable, just, good. His studies also took in each of the philosophical systems of the time. His father had planned a career for Galen in philosophy or politics and took care to expose him to literary. However, Galen states that in around AD145 his father had a dream in which the god Asclepius appeared and commanded Nicon to send his son to study medicine, there he came under the influence of men like Aeschrion of Pergamon, Stratonicus and Satyrus. Asclepiea functioned as spas or sanitoria to which the sick would come to seek the ministrations of the priesthood, romans frequented the temple at Pergamon in search of medical relief from illness and disease. It was also the haunt of notable people such as Claudius Charax the historian, Aelius Aristides the orator, Polemo the sophist, in 148, when he was 19, his father died, leaving him independently wealthy. In 157, aged 28, he returned to Pergamon as physician to the gladiators of the High Priest of Asia, one of the most influential and wealthy men in Asia

Samuel Johnson
–
Johnson was a devout Anglican and committed Tory, and is described by the Oxford Dictionary of National Biography as arguably the most distinguished man of letters in English history. He is also the subject of perhaps the most famous biography in English literature, born in Lichfield, Staffordshire, Johnson attended Pembroke College, Oxford for just over a year, before his lack of funds forced him to leave. After working as a teacher, he moved to London, where he began to write for The Gentlemans Magazine and his early works include the biography Life of Mr Richard Savage, the poems London and The Vanity of Human Wishes, and the play Irene. After nine years of work, Johnsons A Dictionary of the English Language was published in 1755 and it had a far-reaching effect on Modern English and has been described as one of the greatest single achievements of scholarship. This work brought Johnson popularity and success, until the completion of the Oxford English Dictionary 150 years later, Johnsons was viewed as the pre-eminent British dictionary. His later works included essays, an annotated edition of The Plays of William Shakespeare. In 1763, he befriended James Boswell, with whom he travelled to Scotland. Towards the end of his life, he produced the massive and influential Lives of the Most Eminent English Poets, Johnson was a tall and robust man. His odd gestures and tics were disconcerting to some on first meeting him, after a series of illnesses, he died on the evening of 13 December 1784, and was buried in Westminster Abbey. Born on 18 September 1709, to Michael Johnson, a bookseller and he did not cry and, with doubts surrounding the newborns health, his aunt exclaimed that she would not have picked such a poor creature up in the street. Since it was feared that the baby die, the vicar of St Marys was summoned to perform a baptism. Two godfathers were chosen, Samuel Swynfen, a physician and graduate of Pembroke College, Oxford, and Richard Wakefield, a lawyer, coroner, Johnsons health improved and he was put to wet-nurse with Joan Marklew. He soon contracted scrofula, known at time as the Kings Evil because it was thought royalty could cure it. Sir John Floyer, former physician to King Charles II, recommended that the young Johnson should receive the royal touch, however, the ritual was ineffective, and an operation was performed that left him with permanent scars across his face and body. Johnson demonstrated signs of intelligence as a child, and his parents, to his later disgust. His education began at the age of three, and was provided by his mother, who had him memorise and recite passages from the Book of Common Prayer. When Samuel turned four, he was sent to a nearby school, a year later, Johnson went to Lichfield Grammar School, where he excelled in Latin. During this time, Johnson started to exhibit the tics that would influence how people viewed him in his years
