Eye Beam
In the physics inherited from Plato (although rejected by Aristotle), an eye beam generated in the eye was thought to be responsible for the sense of sight. The eye beam darted by the imagined basilisk, for instance, was the agent of its lethal power, given the technical term '' extramission''. The exaggerated eyes of fourth-century Roman emperors like Constantine the Great (''illustration'') reflect this character. The concept found expression in poetry into the 17th century, most famously in John Donne's poem "The Extasie": Our eye-beams twisted, and did thred Our eyes, upon one double string; So to'entergraft our hands, as yet Was all the meanes to make us one, And pictures in our eyes to get Was all our propagation. In the same period John Milton wrote, of having gone blind, "When I consider how my light is spent", meaning that he had lost the capacity to generate eye beams. Later in the century, Newtonian optics and increased understanding of the structure of the ... [...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 ...

Popular Culture
Popular culture (also called mass culture or pop culture) is generally recognized by members of a society as a set of practices, beliefs, artistic output (also known as, popular art or mass art) and objects that are dominant or prevalent in a society at a given point in time. Popular culture also encompasses the activities and feelings produced as a result of interaction with these dominant objects. The primary driving force behind popular culture is the mass appeal, and it is produced by what cultural analyst Theodor Adorno refers to as the "culture industry". Heavily influenced in modern times by mass media, this collection of ideas permeates the everyday lives of people in a given society. Therefore, popular culture has a way of influencing an individual's attitudes towards certain topics. However, there are various ways to define pop culture. Because of this, popular culture is something that can be defined in a variety of conflicting ways by different people across dif ...

Ray Tracing (graphics)
In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images. On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping and path tracing, are generally slower and higher fidelity than scanline rendering methods. Thus, ray tracing was first deployed in applications where taking a relatively long time to render could be tolerated, such as in still computer-generated images, and film and television visual effects (VFX), but was less suited to real-time applications such as video games, where speed is critical in rendering each frame. Since 2018, however, hardware acceleration for real-time ray tracing has become standard on new commercial graphics cards, and graphics APIs have followed suit, allowing developers to use hybrid ray tracing and rasteriz ...

Computer Graphics
Computer graphics deals with generating images with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research. Some topics in computer graphics include user interface design, sprite graphics, rendering, ray tracing, geometry processing, computer animation, vector graphics, 3D modeling, shaders, GPU design, implicit surfaces, visualization, scien ...

Taurus (constellation)
Taurus (Latin for "the Bull") is one of the constellations of the zodiac and is located in the northern celestial hemisphere. Taurus is a large and prominent constellation in the Northern Hemisphere's winter sky. It is one of the oldest constellations, dating back to the Early Bronze Age at least, when it marked the location of the Sun during the spring equinox. Its importance to the agricultural calendar influenced various bull figures in the mythologies of Ancient Sumer, Akkad, Assyria, Babylon, Egypt, Greece, and Rome. Its old astronomical symbol is (♉︎), which resembles a bull's head. A number of features exist that are of interest to astronomers. Taurus hosts two of the nearest open clusters to Earth, the Pleiades and the Hyades, both of which are visible to the naked eye. At first magnitude, the red giant Aldebaran is the brightest star in the constellation. In the northeast part of Taurus is Messier 1, more commonly known as the Crab Nebula, a supernova remn ...

Edward Tregear
Edward Robert Tregear , Ordre des Palmes académiques (1846–1931) was a New Zealand public servant and scholar. He was an architect of New Zealand's advanced social reforms and progressive labour legislation during the 1890s. Biography He was born in Southampton, England, on 1 May 1846, the son of Captain William Henry Tregear, a descendant of an old Cornish family. Tregear was educated in private schools and trained as a civil engineer. He arrived in Auckland in June 1863 and took a position as a surveyor. This work brought him into close contact with the Māori, and he began to study their language and culture. Poverty forced Tregear to enlist in the Auckland Engineer Volunteers. He saw action against the Māori in the Tauranga area and was awarded the New Zealand War Medal. Between 1869 and 1873 he worked as a surveyor on the goldfields at Thames and Coromandel and on Māori lands near Tokoroa. His investments in gold mining and saw milling ventures proved disastrous, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnt Norton
''Burnt Norton'' is the first poem of T. S. Eliot's ''Four Quartets''. He created it while working on his play '' Murder in the Cathedral'', and it was first published in his ''Collected Poems 1909–1935'' (1936). The poem's title refers to the manor house Eliot visited with Emily Hale in the Cotswolds. The manor's garden serves as an important image within the poem. Structurally, the poem is based on Eliot's ''The Waste Land'', with passages of the poem related to those excised from '' Murder in the Cathedral''. The central discussion within the poem is on the nature of time and salvation. Eliot emphasises the need of the individual to focus on the present moment and to know that there is a universal order. By understanding the nature of time and the order of the universe, mankind is able to recognise God and seek redemption. Many reviewers of ''Burnt Norton'' focused on the uniquity and beauty of the poem. However, others complained that the poem does not reflect Eliot's ea ...

Artemis
In ancient Greek mythology and religion, Artemis (; grc-gre, Ἄρτεμις) is the goddess of the hunt, the wilderness, wild animals, nature, vegetation, childbirth, care of children, and chastity. She was heavily identified with Selene, the Moon, and Hecate, another Moon goddess, and was thus regarded as one of the most prominent lunar deities in mythology, alongside the aforementioned two.Smiths.v. Artemis/ref> She would often roam the forests of Greece, attended by her large entourage, mostly made up of nymphs, some mortals, and hunters. The goddess Diana is her Roman equivalent. In Greek tradition, Artemis is the daughter of the sky god and king of gods Zeus and Leto, and the twin sister of Apollo. In most accounts, the twins are the products of an extramarital liaison. For this, Zeus' wife Hera forbade Leto from giving birth anywhere on land. Only the island of Delos gave refuge to Leto, allowing her to give birth to her children. Usually, Artemis i ...

Algernon Swinburne
Algernon Charles Swinburne (5 April 1837 – 10 April 1909) was an English poet, playwright, novelist, and critic. He wrote several novels and collections of poetry such as '' Poems and Ballads'', and contributed to the famous Eleventh Edition of the ''Encyclopædia Britannica''. Swinburne wrote about many taboo topics, such as lesbianism, sado-masochism, and anti-theism. His poems have many common motifs, such as the ocean, time, and death. Several historical people are featured in his poems, such as Sappho ("Sapphics"), Anactoria ("Anactoria"), and Catullus ("To Catullus"). Biography Swinburne was born at 7 Chester Street, Grosvenor Place, London, on 5 April 1837. He was the eldest of six children born to Captain (later Admiral) Charles Henry Swinburne (1797–1877) and Lady Jane Henrietta, daughter of the 3rd Earl of Ashburnham, a wealthy Northumbrian family. He grew up at East Dene in Bonchurch on the Isle of Wight. The Swinburnes also had a London home at Whitehal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Grosseteste
Robert Grosseteste, ', ', or ') or the gallicised Robert Grosstête ( ; la, Robertus Grossetesta or '). Also known as Robert of Lincoln ( la, Robertus Lincolniensis, ', &c.) or Rupert of Lincoln ( la, Rubertus Lincolniensis, &c.). ( ; la, Robertus Grosseteste; 8 or 9 October 1253), also known as Robert Greathead or Robert of Lincoln, was an English statesman, scholastic philosopher, theologian, scientist and Bishop of Lincoln. He was born of humble parents in Suffolk (according to the early 14th-century chronicler Nicholas Trevet), but the associations with the village of Stradbroke is a post-medieval tradition. Upon his death, he was revered as a saint in England, but attempts to procure a formal canonisation failed. A. C. Crombie called him "the real founder of the tradition of scientific thought in medieval Oxford, and in some ways, of the modern English intellectual tradition". Scholarly career There is very little direct evidence about Grosseteste's education. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a ''geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isaac Newton
Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a " natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. In the , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
