Il Saggiatore
''The Assayer'' ( it, Il Saggiatore) was a book published in Rome by Galileo Galilei in October 1623 and is generally considered to be one of the pioneering works of the scientific method, first broaching the idea that the book of nature is to be read with mathematical tools rather than those of scholastic philosophy, as generally held at the time. Grassi on the comets The context of the essay was to reply to the treatise ''Libra astronomica ac philosophica'' of 1619 by Orazio Grassi, a Jesuit mathematician at the Collegio Romano, which used the pseudonym of Lotario Sarsi Sigensano. The debate between Galileo and Grassi started in 1618, when the latter published ''Disputatio astronomica de tribus cometis anni MDCXVIII'', in which he asserted that comets are celestial bodies. Grassi adopted Tycho Brahe's Tychonic system, in which the other planets of the Solar System orbit around the Sun, which, in turn, orbits around the Earth. In his ''Disputatio'' Grassi referenced many of Gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copernicanism
Copernican heliocentrism is the astronomical scientific modeling, model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular trajectory, paths, modified by epicycles, and at uniform speeds. The Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe. Although he had circulated an outline of his own heliocentric theory to colleagues sometime before 1514, he did not decide to publish it until he was urged to do so later by his pupil Rheticus. Copernicus's challenge was to present a practical alternative to the Ptolemaic model by more elegantly and accurately determining the length of a solar year while preserving the Pythagoreanism, metaphysical implications of a mathematically ordered cosmos. Thus, his heliocentric model retained several of the Ptolemaic e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astrolabe
An astrolabe ( grc, ἀστρολάβος ; ar, ٱلأَسْطُرلاب ; persian, ستارهیاب ) is an ancient astronomical instrument that was a handheld model of the universe. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. Historically used by astronomers, it is able to measure the altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe's importance comes not only from the early developments into the study of astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philosopher
A philosopher is a person who practices or investigates philosophy. The term ''philosopher'' comes from the grc, φιλόσοφος, , translit=philosophos, meaning 'lover of wisdom'. The coining of the term has been attributed to the Greek thinker Pythagoras (6th century BCE).. In the Classics, classical sense, a philosopher was someone who lived according to a certain way of life, focusing upon resolving Meaning of life, existential questions about the human condition; it was not necessary that they discoursed upon Theory, theories or commented upon authors. Those who most arduously committed themselves to this lifestyle would have been considered ''philosophers''. In a modern sense, a philosopher is an intellectual who contributes to one or more branches of philosophy, such as aesthetics, ethics, epistemology, philosophy of science, logic, metaphysics, social theory, philosophy of religion, and political philosophy. A philosopher may also be someone who has worked in the hum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

From the ancient world (at least since Aristotle) until the 19th century, ''natural philosophy'' was the common term for the study of physics (nature), a broad term that included botany, zoology, anthropology, and chemistry as well as what we now call physics. It was in the 19th century that the concept of science received its modern shape, with different subjects within science emerging, such as astronomy, biology, and physics. Institutions and communities devoted to science were founded. Isaac Newton's book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ipse Dixit
''Ipse dixit'' (Latin for "he said it himself") is an assertion without proof, or a dogmatic expression of opinion.Whitney, William Dwight. (1906)"''Ipse dixit''" ''The Century dictionary and cyclopedia,'' pp. 379–380; Westbrook, Robert B"John Dewey and American Democracy", p. 359 The fallacy of defending a proposition by baldly asserting that it is "just how it is" distorts the argument by opting out of it entirely: the claimant declares an issue to be intrinsic, and not changeable.VanderMey, Randall ''et al.'' (2011)''Comp'', p. 183 excerpt: "Bare assertion. The most basic way to distort an issue is to deny that it exists. This fallacy claims, 'That's just how it is.' " History The Latin form of the expression comes from the Roman orator and philosopher Marcus Tullius Cicero (106–43 BC) in his theological studies ''De Natura Deorum'' (''On the Nature of the Gods'') and is his translation of the Greek expression (with the identical meaning) ''autòs épha'' (), an argumen ...

Barberini
The House of Barberini are a family of the Italian nobility that rose to prominence in 17th century Rome. Their influence peaked with the election of Cardinal Maffeo Barberini to the papal throne in 1623, as Pope Urban VIII. Their urban palace, the Palazzo Barberini, completed in 1633 by Bernini, today houses Italy's Galleria Nazionale d'Arte Antica (National Gallery of Ancient Art). Early history The Barberini family were originally a family of minor nobility from the Tuscan town of Barberino Val d'Elsa, who settled in Florence during the early part of the 11th century. This cites: * A. von Reumont, ''Geschichte der Stadt Rom'' (Berlin, 1868), iii. b. 611–612, 615, 617, &c. * ''Almanach de Gotha'' (Gotha, 1902). * J. H. Douglas, ''The Principal Noble Families of Rome'' (Rome, 1905). Carlo Barberini (1488–1566) and his brother Antonio Barberini (1494–1559) were successful Florentine grain, wool and textile merchants. In 1530 Antonio participated in the defense of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pope Urban VIII
Pope Urban VIII ( la, Urbanus VIII; it, Urbano VIII; baptised 5 April 1568 – 29 July 1644), born Maffeo Vincenzo Barberini, was head of the Catholic Church and ruler of the Papal States from 6 August 1623 to his death in July 1644. As pope, he expanded the papal territory by force of arms and advantageous politicking, and was also a prominent patron of the arts and a reformer of Church missions. However, the massive debts incurred during his pontificate greatly weakened his successors, who were unable to maintain the papacy's longstanding political and military influence in Europe. He was also an opponent of Copernicanism and involved in the Galileo affair. He is the last pope to date to take the pontifical name "Urban". Biography Early life He was born Maffeo Vincenzo Barberini in April 1568 to Antonio Barberini, a Florentine nobleman, and Camilla Barbadoro. He was born at Barberino Val d'Elsa in "Tafania" house. His father died when he was only three years old and hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
