In the 13th century a rediscovery of Greek and Roman literature occurred across Europe that eventually led to the development of the humanist movement in the next century. In addition to emphasizing Greek and Latin scholarship, humanists believed that each individual had significance within society. The growth of an interest in humanism led to the changes in the arts and sciences that form common conceptions of the Renaissance.Revival of ideas spread through print The 14th century to the 16th century – during which time printing process was invented and which led to pace up the print media communication - was a period of economic flux in Europe; the most extensive changes took place in Italy.

After the death of King Frederick II in 1250, emperors lost power in Italy and throughout Europe; none of Frederick's successors equaled him. Power fell instead into the hands of various popes.During the Renaissance small Italian republics developed into dictatorships as the centers of power moved from the landed estates to the cities. Europe itself slowly developed into groups of self-sufficient compartments. At the height of the Renaissance there were five major city-states in Italy: the combined state of Naples and Sicily, the Papal State, Florence, Milan, and Venice. ScienceBeginning in the latter half of the 15th century, a humanist faith in classical scholarship led to the search for ancient (hand-written) texts that would increase current scientific knowledge.

Among the works rediscovered were Galen's physiological and anatomical studies and Ptolemy's Geography. Botany, zoology, magic and astrology were developed during the Renaissance as a result of the study of ancient texts. Since printing techniques were available, it made the task of sending the old research still safe in hand written texts, to scholars living distant countries.Scientific thinkers such as Leonardo da Vinci, Nicolaus Copernicus, Galileo and Johannes Kepler attempted to refine earlier thought on astronomy. Among Leonardo's discoveries were the revelation that thrown or shot projectiles move in one curved trajectory rather than two; metallurgical techniques that allowed him to make great sculptures; and anatomical observations that increased the accuracy of his drawings.

The work done on old ideas kept appearing in books printed in different countries.In 1543 Copernicus wrote De revolutionibus, a work that placed the sun at the center of the universe and the planets in order around it; his work was an attempt to revise the earlier writings of Ptolemy. Galileo's most famous invention was an accurate telescope through which he observed the heavens; he recorded his findings in Siderius nuncius [starry messenger]. Galileo's Dialogo...

sopra i due massimi sistemi del mondo [dialogue concerning the two chief world systems] (1632), for which he was denounced by the pope, resulted in his living under house arrest for the rest of his life. Tycho Brahe gave an accurate estimate of planetary positions and refuted the Aristotelian theory that placed the planets within crystal spheres. Kepler was the first astronomer to suggest that planetary orbits were elliptical.Literature Printing technique was now helping the scholars in the west greatly who produced books one after the other to create a mark on the thinking of people about the physical things and the motion of moons and stars. These were the initial phase when the world was about to embark on mass communication through the printed words.

Humanism in Renaissance rhetoric was a reaction to Aristotelian scholasticism, as espoused by Francis Bacon, Averroës, and Albertus Magnus, among others. While the scholastics claimed a logical connection between word and thought, the humanists differentiated between physical utterance and intangible meditation; they gave common usage priority over sets of logical rules.The humanists also sought to emulate classical values. Joseph Webbe wrote textbooks that taught Latin through reconstruction of the sentences of classical authors from individual phrases and clauses. Roger Ascham taught that one could learn to speak effectively by studying the speeches of ancient orators.

Thomas Elyot wrote The Book Named the Governor, which suggested rules for effective statesmanship. Thomas More's most significant contribution to humanism was Utopia, a design for an ideal society based primarily on works by classical authors.The effect of humanism on English literature was wide and far-reaching. It is evidenced, for example, in the works of Ben Jonson and William Shakespeare. The poems and plays of Jonson often center on the difference between virtue and vice; Jonson considers sincerity, honesty, self-discipline, and concern to be chief virtues, while dissimulation, lying, or masking of identity is vicious behavior. His Volpone and The Alchemist exemplify humanist values.

In a play such as Shakespeare's Tempest, a main character (Prospero) embodies a full range of human abilities: father, creator, ruler, magician, master, and scholar. In addition, Shakespeare took subject matter for many plays from classical sources (e.g., Coriolanus, Troilus and Cressida, and Julius Caesar).

In France Michel de Montaigne and François Rabelais were the most important proponents of humanist thought. Montaigne's essays are memorable for their clear statement of an individual's beliefs and their careful examination of society. In “On the Education of Children,” he suggests a remaking of secondary education according to classical models. The Renaissance Italian Leone Battista Alberti is famed for a series of dialogues in which he teaches classical virtues in a vernacular tongue. Niccolò Machiavelli wrote Principe, in which he memorably described the various shapes a ruler must assume in order to become an effective leader, and Discorsi [the discourses], in which he studies Livy in a search for classical values.

The Book of the Courtier by Baldassare Castiglione is essentially about Castiglione himself; in it the author delineates the characteristics of a perfect gentleman.All what was done in the literature books was printed and books traveled from one point of the continent to another and read widely because high number of printed version made it possible for more people to participate in discussions on new ideas in natural and social sciences.Scientific changes The event which most historians of science call the scientific revolution can be dated roughly as having begun in 1543, the year in which Nicolaus Copernicus published his De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) and Andreas Vesalius published his De humani corporis fabrica (On the Fabric of the Human body). As with many historical demarcations, historians of science disagree about its boundaries, some seeing elements contributing to the revolution as early as the 14th century and finding its last stages in chemistry and biology in the 18th and 19th centuries. There is general agreement, however, that the intervening period saw a fundamental transformation in scientific ideas in physics, astronomy and biology, in institutions supporting scientific investigation, and in the more widely held picture of the universe.Emergence of the revolution Since the time of Voltaire, some observers have considered that a revolutionary change in thought, called in recent times a scientific revolution, took place around the year 1600; that is, that there were dramatic and historically rapid changes in the ways in which scholars thought about the physical world and studied it.

Science, as it is treated in this account, is essentially understood and practiced in the modern world; with various "other narratives" or alternate ways of knowing omitted. Alexandre Koyré coined the term and definition of 'The Scientific Revolution' in 1939, which later influenced the work of traditional historians A. Rupert Hall and J.D. Bernal and subsequent historiography on the subject (Steven Shapin, The Scientific Revolution, 1996).
