Perspectiva
Vitello ( pl, Witelon; german: Witelo; – 1280/1314) was a friar, theologian, natural philosopher and an important figure in the history of philosophy in Poland. Name Vitello's name varies with some sources. In earlier publications he was quoted as Erazmus Ciolek Witelo, Erazm Ciołek, Vitellio and Vitulon. Today, he is usually referred to by his Latin name Vitello Thuringopolonis, often shortened to Vitello. Life Vitello's exact birth-name and birthplace are uncertain. He was most likely born around 1230 in Silesia, in the vicinity of Legnica. His mother came from a Polish knightly house, while his father was a German settler from Thuringia. He called himself, in Latin, "''Thuringorum et Polonorum filius''" — "a son of Thuringians and Poles." He studied at Padua University about 1260, then went on to Viterbo. He became friends with William of Moerbeke, the translator of Aristotle from Greek language into Latin. Vitello's major surviving work on optics, ''Perspectiva'', ...

History Of Philosophy In Poland
The history of philosophy in Poland parallels the evolution of philosophy in Europe in general. Overview Polish philosophy drew upon the broader currents of European philosophy, and in turn contributed to their growth. Some of the most momentous Polish contributions came, in the thirteenth century, from the Scholastic philosopher and scientist Vitello, and, in the sixteenth century, from the Renaissance polymath Nicolaus Copernicus. Subsequently, the Polish–Lithuanian Commonwealth partook in the intellectual ferment of the Enlightenment, which for the multi-ethnic Commonwealth ended not long after the 1772-1795 partitions and political annihilation that would last for the next 123 years, until the collapse of the three partitioning empires in World War I. The period of Messianism, between the November 1830 and January 1863 Uprisings, reflected European Romantic and Idealist trends, as well as a Polish yearning for political resurrection. It was a period of maximalis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Of Optics
The ''Book of Optics'' ( ar, كتاب المناظر, Kitāb al-Manāẓir; la, De Aspectibus or ''Perspectiva''; it, Deli Aspecti) is a seven-volume treatise on optics and other fields of study composed by the medieval Arab scholar Ibn al-Haytham, known in the West as Alhazen or Alhacen (965–c. 1040 AD). The ''Book of Optics'' presented experimentally founded arguments against the widely held extramission theory of vision (as held by Euclid in his ''Optica''), and proposed the modern intromission theory, the now accepted model that vision takes place by light entering the eye.D. C. Lindberg (1976), ''Theories of Vision from al-Kindi to Kepler'', Chicago, Univ. of Chicago Press The book is also noted for its early use of the scientific method, its description of the camera obscura, and its formulation of Alhazen's problem. The book extensively affected the development of optics, physics and mathematics in Europe between the 13th and 17th centuries. Vision theory B ...

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

William Of Moerbeke
William of Moerbeke, O.P. ( nl, Willem van Moerbeke; la, Guillelmus de Morbeka; 1215–35 – 1286), was a prolific medieval translator of philosophical, medical, and scientific texts from Greek language into Latin, enabled by the period of Latin rule of the Byzantine Empire. His translations were influential in his day, when few competing translations were available, and are still respected by modern scholars. Biography Moerbeke was Flemish by origin (his surname indicating an origin in Moerbeke near Geraardsbergen), and a Dominican by vocation. Little is known of his life. In the spring of 1260, he was at either Nicaea or Nicles, in the Peloponnese; in the autumn of the same year, he was at Thebes, where the Dominicans had been since 1253 and where he dated his translation of Aristotle's '' De partibus animalium''. In turn he resided at the pontifical court of Viterbo (with evidence for his residence here in 22 November 1267, May 1268, and 15 June 1271) and met the ...

Refraction
In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence ''θ1'' and angle of refraction ''θ2'' is equal to the ratio of phase velocities (''v''1 / ''v''2) in the two media, or equivalently, to the refractive indices (''n''2 / ''n''1) of the two media. :\frac =\frac=\frac Optical prisms and lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subconscious
In psychology, the subconscious is the part of the mind that is not currently of focal awareness. Scholarly use of the term The word ''subconscious'' represents an anglicized version of the French ''subconscient'' as coined in 1889 by the psychologist Pierre Janet (1859–1947), in his doctorate of letters thesis, ''De l'Automatisme Psychologique''. Janet argued that underneath the layers of critical-thought functions of the conscious mind lay a powerful awareness that he called the subconscious mind.Henri F. Ellenberger, ''The Discovery of the Unconscious'' (1970) In the strict psychological sense, the adjective is defined as "operating or existing outside of consciousness". Locke and Kristof write that there is a limit to what can be held in conscious focal awareness, an alternative storehouse of one's knowledge and prior experience is needed, which they label the subconscious. Psychoanalysis Sigmund Freud used the term "subconscious" in 1893 to describe associations and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association (psychology)
Association in psychology refers to a mental connection between concepts, events, or mental states that usually stems from specific experiences.Klein, Stephen (2012). ''Learning: Principles and Applications'' (6 ed.). SAGE Publications. . Associations are seen throughout several schools of thought in psychology including behaviorism, associationism, psychoanalysis, social psychology, and structuralism. The idea stems from Plato and Aristotle, especially with regard to the succession of memories, and it was carried on by philosophers such as John Locke, David Hume, David Hartley, and James Mill.Boring, E. G. (1950) It finds its place in modern psychology in such areas as memory, learning, and the study of neural pathways. Learned associations Associative learning is when a subject creates a relationship between stimuli (e.g. auditory or visual) or behavior and the original stimulus. The higher the concreteness of stimulus items, the more likely are they to evoke sensor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Lorenzo Ghiberti
Lorenzo Ghiberti (, , ; 1378 – 1 December 1455), born Lorenzo di Bartolo, was an Italian Renaissance sculptor from Florence, a key figure in the Early Renaissance, best known as the creator of two sets of bronze doors of the Florence Baptistery, the later one called by Michelangelo the ''Gates of Paradise''. Trained as a goldsmith and sculptor, he established an important workshop for sculpture in metal. His book of ''Commentarii'' contains important writing on art, as well as what may be the earliest surviving autobiography by any artist. Ghiberti's career was dominated by his two successive commissions for pairs of bronze doors to the Florence Baptistery (Battistero di San Giovanni). They are recognized as a major masterpiece of the Early Renaissance, and were famous and influential from their unveiling. Early life Ghiberti was born in 1378 in Pelago, a comune 20 km from Florence. It is said that Lorenzo was the son of Cione di Ser Buonaccorso Ghiberti and Fiore Ghi ...
