Dircksian Phantasmagoria
Henry Dircks FRSE FCS (26 August 1806– 17 September 1873) was an English engineer who is considered to have been the main designer of the projection technique known as ''Pepper's ghost'' in 1858. It is named after John Henry Pepper who implemented a working version of the device in 1862. Dircks also investigated attempts at the invention of a perpetual motion device, writing that those who sought to create such a thing were "half-learned" or "totally ignorant". Life and career Dircks was born in Liverpool on 26 August 1806. He was apprenticed to a mercantile firm and spent much of his free time studying practical mechanics, chemistry, and literature. Around the mid-1820s he began lecturing about chemistry and electricity while writing literary articles in the local press and scientific papers in the ''Mechanics' Magazine'' and other journals. In 1837 he became a life member of the British Association, and afterwards contributed papers to its proceedings. Two years later he wro ...

Perpetual Motion
Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate either the first law of thermodynamics, first or second law of thermodynamics or both. These laws of thermodynamics apply regardless of the size of the system. For example, the motions and rotations of celestial bodies such as planets may appear perpetual, but are actually subject to many processes that slowly dissipate their kinetic energy, such as solar wind, interstellar medium resistance, gravitational radiation and thermal radiation, so they will not keep moving forever. Thus, machines that extract energy from finite sources will not operate indefinitely, because they are driven by the energy stored in the source, which will eventually be exhausted. A common example is devices powered by ocean currents, whose energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legum Doctor
Legum Doctor (Latin: “teacher of the laws”) (LL.D.) or, in English, Doctor of Laws, is a doctorate-level academic degree in law or an honorary degree, depending on the jurisdiction. The double “L” in the abbreviation refers to the early practice in the University of Cambridge to teach both canon law and civil law (Doctor of both laws), with the double “L” itself indicating the plural, although Cambridge now gives the degree the name Doctor of Law in English. This contrasts with the practice of the University of Oxford, where the degree that survived from the Middle Ages is the DCL or Doctor of Civil Law (only). European and Commonwealth usage In the United Kingdom, Australia, New Zealand, and a number of European countries, the LL.D. is a higher doctorate usually awarded on the basis of exceptionally insightful and distinctive publications that contain significant and original contributions to the study of law. In South Africa, the LL.D. is awarded by many unive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peppers Ghost
Pepper's ghost is an illusion technique used in the theatre, cinema, amusement parks, museums, television, and concerts. It is named after the English scientist John Henry Pepper (1821–1900) who began popularising the effect with a theatre demonstration in 1862. This launched an international vogue for ghost-themed plays, which used this novel stage effect, during the 1860s and subsequent decades. The illusion is widely used for entertainment and publicity purposes. These include the Girl-to-Gorilla trick found in old carnival sideshows and the appearance of "ghosts" at the Haunted Mansion and the "Blue Fairy" in Pinocchio's Daring Journey, both at Disneyland in California. Teleprompters are a modern implementation of Pepper's ghost. The technique was used to display a life-size Illusion of Kate Moss at the 2006 runway show for the Alexander McQueen collection ''The Widows of Culloden.'' In the 2010s the technique has been used to make virtual artists appear onstage in app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enlightenment (spiritual)
Used in a religious sense, enlightenment translates several Glossary of Buddhism, Buddhist terms and concepts, most notably ''bodhi'', ''kensho,'' and ''satori''. Related terms from Asian religions are ''kaivalya'' and ''moksha'' (liberation) in Hinduism, ''Kevala Jnana'' in Jainism, and ''ushta'' in Zoroastrianism. In Christianity, the word "enlightenment" is rarely used, except to refer to the Age of Enlightenment and its influence on Christianity. Roughly equivalent terms in Christianity may be Divine illumination, illumination, kenosis, metanoia (theology), metanoia, revelation, salvation, Divinization (Christian), theosis, and Religious conversion, conversion. Perennial philosophy, Perennialists and Universalism, Universalists view enlightenment and mysticism as equivalent terms for religious or spiritual insight. Asian cultures and religions Buddhism The English term ''enlightenment'' is the western translation of the abstract noun ''bodhi'', the knowledge or wisdom, ...

Magic Lantern
The magic lantern, also known by its Latin name , is an early type of image projector that used pictures—paintings, prints, or photographs—on transparent plates (usually made of glass), one or more lenses, and a light source. Because a single lens inverts an image projected through it (as in the phenomenon which inverts the image of a camera obscura), slides were inserted upside down in the magic lantern, rendering the projected image correctly oriented. It was mostly developed in the 17th century and commonly used for entertainment purposes. It was increasingly used for education during the 19th century. Since the late 19th century, smaller versions were also mass-produced as toys. The magic lantern was in wide use from the 18th century until the mid-20th century when it was superseded by a compact version that could hold many 35 mm photographic slides: the slide projector. Technology Apparatus The magic lantern used a concave mirror behind a light source to direct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phantasmagoria
Phantasmagoria (, also fantasmagorie, fantasmagoria) was a form of horror theatre that (among other techniques) used one or more magic lanterns to project frightening images, such as skeletons, demons, and ghosts, onto walls, smoke, or semi-transparent screens, typically using rear projection to keep the lantern out of sight. Mobile or portable projectors were used, allowing the projected image to move and change size on the screen, and multiple projecting devices allowed for quick switching of different images. In many shows, the use of spooky decoration, total darkness, (auto-)suggestive verbal presentation, and sound effects were also key elements. Some shows added a variety of sensory stimulation, including smells and electric shocks. Such elements as required fasting, fatigue (late shows), and drugs have been mentioned as methods of making sure spectators would be more convinced of what they saw. The shows started under the guise of actual séances in Germany in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiritualism
Spiritualism is the metaphysical school of thought opposing physicalism and also is the category of all spiritual beliefs/views (in monism and dualism) from ancient to modern. In the long nineteenth century, Spiritualism (when not lowercase) became most known as a social religious movement according to which the laws of nature and of God include "the continuity of consciousness after the transition of death" and "the possibility of communication between those living on Earth and those who have made the transition". The afterlife, or the " spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to a third belief: that spirits are capable of providing useful insight regarding moral and ethical issues, as well as about the nature of God. Some spiritualists will speak of a concept which they refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark Akenside
Mark Akenside (9 November 1721 – 23 June 1770) was an English poet and physician. Biography Akenside was born at Newcastle upon Tyne, England, the son of a butcher. He was slightly lame all his life from a wound he received as a child from his father's cleaver. All his relations were Dissenters, and, after attending the Royal Free Grammar School of Newcastle, and a dissenting academy in the town, he was sent in 1739 to the University of Edinburgh to study theology with a view to becoming a minister, his expenses being paid from a special fund set aside by the dissenting community for the education of their pastors. He had already contributed ''The Virtuoso, in imitation of Spenser's style and stanza'' (1737) to the ''Gentleman's Magazine'', and in 1738 ''A British Philippic, occasioned by the Insults of the Spaniards, and the present Preparations for War'' (also published separately). After one winter as a theology student, Akenside changed to medicine as his field of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Monckton Milnes, 1st Baron Houghton
Richard Monckton Milnes, 1st Baron Houghton, FRS (19 June 1809 – 11 August 1885) was an English poet, patron of literature and a politician who strongly supported social justice. Background and education Milnes was born in London, the son of Robert Pemberton Milnes, of Fryston Hall, Castleford, West Yorkshire, and the Honourable Henrietta, daughter of Robert Monckton-Arundell, 4th Viscount Galway. His grandmother was Rachel Slater Milnes (née Busk, 1760-1835), niece of Sir Wadsworth Busk. Milnes was educated privately, and entered Trinity College, Cambridge, in 1827. There he was drawn into a literary set, and became a member of the famous Apostles Club, which then included Alfred Lord Tennyson, Arthur Hallam, Richard Chenevix Trench, Joseph Williams Blakesley, and others. After graduating with an M.A. in 1831, Milnes travelled abroad, spending some time at the University of Bonn. He went to Italy and Greece, and published in 1834 a volume of ''Memorials of a Tour in som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poetry
Poetry (derived from the Greek ''poiesis'', "making"), also called verse, is a form of literature that uses aesthetic and often rhythmic qualities of language − such as phonaesthetics, sound symbolism, and metre − to evoke meanings in addition to, or in place of, a prosaic ostensible meaning. A poem is a literary composition, written by a poet, using this principle. Poetry has a long and varied history, evolving differentially across the globe. It dates back at least to prehistoric times with hunting poetry in Africa and to panegyric and elegiac court poetry of the empires of the Nile, Niger, and Volta River valleys. Some of the earliest written poetry in Africa occurs among the Pyramid Texts written during the 25th century BCE. The earliest surviving Western Asian epic poetry, the '' Epic of Gilgamesh'', was written in Sumerian. Early poems in the Eurasian continent evolved from folk songs such as the Chinese ''Shijing'', as well as religious hymns (the S ...

Electrometallurgy
Electrometallurgy is a method in metallurgy that uses electrical energy to produce metals by electrolysis. It is usually the last stage in metal production and is therefore preceded by pyrometallurgical or hydrometallurgical operations. The electrolysis can be done on a molten metal oxide (smelt electrolysis) which is used for example to produce aluminium from aluminium oxide via the Hall-Hérault process. Electrolysis can be used as a final refining stage in pyrometallurgical metal production (electrorefining) and it is also used for reduction of a metal from an aqueous metal salt solution produced by hydrometallurgy (electrowinning). Processes Electrometallurgy is the field concerned with the processes of metal electrodeposition. There are four categories of these processes: *Electrolysis *Electrowinning, the extraction of metal from ores *Electrorefining, the purification of metals. Metal powder production by electrodeposition is included in this category, or sometimes e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
