Continuum (Ligeti)
''Continuum'' for harpsichord is a musical composition by György Ligeti composed in 1968, and dedicated to the contemporary harpsichordist, Antoinette Vischer. The composer describes the conception and result of its technique: Amy Bauer (2004, p. 130) describes the piece as ''trompe-l'œil'', creating "a sense of stasis through extremely rapid activity." She compares it to a patient's description of the schizophrenic experience of, "an intense cerebral activity in which inner experiences took place at greatly increased speed, so that much more than usual happened per minute of external time. The result was to give an effect of slow motion." (Sass 1992) This piece has also been arranged for barrel organ and for two player pianos by the composer. The piece has also been compared by classical music reviewers to the magnetic fluctuations of comet 67P/Churyumov–Gerasimenko as detected by the space probe Philae after the fluctuations were artistically sonificated by a German ...

Harpsichord
A harpsichord ( it, clavicembalo; french: clavecin; german: Cembalo; es, clavecín; pt, cravo; nl, klavecimbel; pl, klawesyn) is a musical instrument played by means of a keyboard. This activates a row of levers that turn a trigger mechanism that plucks one or more strings with a small plectrum made from quill or plastic. The strings are under tension on a soundboard, which is mounted in a wooden case; the soundboard amplifies the vibrations from the strings so that the listeners can hear it. Like a pipe organ, a harpsichord may have more than one keyboard manual, and even a pedal board. Harpsichords may also have stop buttons which add or remove additional octaves. Some harpsichords may have a buff stop, which brings a strip of buff leather or other material in contact with the strings, muting their sound to simulate the sound of a plucked lute. The term denotes the whole family of similar plucked-keyboard instruments, including the smaller virginals, muselar, and spinet. ...

Stasis (fiction)
A stasis or stasis field, in science fiction, is a confined area of space in which time has been stopped or the contents have been rendered motionless. Overview A stasis field is imagined to be a region in which a stasis process is in effect. Stasis fields in fictional settings often have several common characteristics. These include infinite or nearly infinite rigidity, making them "unbreakable objects" and a perfect or nearly-perfect reflective surface. Most science fiction plots rely on a physical device to establish this region. When the device is deactivated, the stasis field collapses, and the stasis effect ends. Time is often suspended in stasis fields. Such fields thus have the additional property of protecting non-living materials from deterioration. This time dilation can be, from an in-universe perspective, absolute; something thrown into the field, has the field triggered and then reactivated, would fly out as if nothing had happened. Storylines using such fields of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philae (spacecraft)
''Philae'' ( or ) was a robotic European Space Agency lander that accompanied the ''Rosetta'' spacecraft until it separated to land on comet 67P/Churyumov–Gerasimenko, ten years and eight months after departing Earth. On 12 November 2014, ''Philae'' touched down on the comet, but it bounced when its anchoring harpoons failed to deploy and a thruster designed to hold the probe to the surface did not fire. After bouncing off the surface twice, ''Philae'' achieved the first-ever "soft" (nondestructive) landing on a comet nucleus, although the lander's final, uncontrolled touchdown left it in a non-optimal location and orientation. Despite the landing problems, the probe's instruments obtained the first images from a comet's surface. Several of the instruments on ''Philae'' made the first direct analysis of a comet, sending back data that would be analysed to determine the composition of the surface. In October 2020, scientific journal ''Nature'' published an article which re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
67P/Churyumov–Gerasimenko
67P/Churyumov–Gerasimenko (abbreviated as 67P or 67P/C–G) is a Jupiter-family comet, originally from the Kuiper belt, with a current orbital period of 6.45 years, a rotation period of approximately 12.4 hours and a maximum velocity of . Churyumov–Gerasimenko is approximately at its longest and widest dimensions. It was first observed on photographic plates in 1969 by Soviet astronomers Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko, after whom it is named. It most recently came to perihelion (closest approach to the Sun) on 2 November 2021, and will next come to perihelion on 9 April 2028. Churyumov–Gerasimenko was the destination of the European Space Agency's ''Rosetta'' mission, launched on 2 March 2004. ''Rosetta'' rendezvoused with Churyumov–Gerasimenko on 6 August 2014 and entered orbit on 10 September 2014. ''Rosetta'' lander, ''Philae'', landed on the comet's surface on 12 November 2014, becoming the first spacecraft to land on a comet nucleu ...

Player Piano
A player piano (also known as a pianola) is a self-playing piano containing a pneumatic or electro-mechanical mechanism, that operates the piano action via programmed music recorded on perforated paper or metallic rolls, with more modern implementations using MIDI. The rise of the player piano grew with the rise of the mass-produced piano for the home, in the late 19th and early 20th century. Sales peaked in 1924, then declined, as the improvement in phonograph recordings due to electrical recording methods developed in the mid-1920s. The advent of electrical amplification in home music reproduction via radio in the same period helped cause their eventual decline in popularity, and the stock market crash of 1929 virtually wiped out production. History In 1896, Edwin S. Votey invented the first practical pneumatic piano player, called the Pianola. This mechanism came into widespread use in the 20th century, and was all-pneumatic, with foot-operated bellows providing a sour ...

Barrel Organ
A barrel organ (also called roller organ or crank organ) is a French mechanical musical instrument consisting of bellows and one or more ranks of pipes housed in a case, usually of wood, and often highly decorated. The basic principle is the same as a traditional pipe organ, but rather than being played by an organist, the barrel organ is activated either by a person turning a crank, or by clockwork driven by weights or springs. The pieces of music are encoded onto wooden barrels (or cylinders), which are analogous to the keyboard of the traditional pipe organ. A person (or in some cases, a trained animal) who plays a barrel organ is known as an organ grinder. Terminology There are many names for the barrel organ, such as hand organ, cylinder organ, box organ (though that can also mean a positive organ), street organ, grinder organ, and Low Countries organ. In French names include ''orgue à manivelle'' ("crank organ") and ''orgue de Barbarie'' ("Barbary organ"); German names i ...

Slow Motion
Slow motion (commonly abbreviated as slo-mo or slow-mo) is an effect in film-making whereby time appears to be slowed down. It was invented by the Austrian priest August Musger in the early 20th century. This can be accomplished through the use of high-speed cameras and then playing the footage produced by such cameras at a normal rate like 30 fps, or in post production through the use of software. Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second). Slow motion can also be achieved by playing normally recorded footage at a slower speed. This technique is more often applied to video subjected to instant replay than to film. A third technique uses computer software post-processing to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerebrum
The cerebrum, telencephalon or endbrain is the largest part of the brain containing the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system. The cerebrum prenatal development, develops prenatally from the forebrain (prosencephalon). In mammals, the Dorsum (biology), dorsal telencephalon, or Pallium (neuroanatomy), pallium, develops into the cerebral cortex, and the ventral telencephalon, or Pallium (neuroanatomy), subpallium, becomes the basal ganglia. The cerebrum is also divided into approximately symmetric Lateralization of brain function, left and right cerebral hemispheres. With the assistance of the cerebellum, the cerebrum controls all voluntary actions in the human body. Structure The cerebrum is the largest part of the brain. Depending upon the position of the animal it lies eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizophrenic
Schizophrenia is a mental disorder characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social withdrawal, Reduced affect display, decreased emotional expression, and apathy. Symptoms typically Prodrome, develop gradually, begin during young adulthood, and in many cases never become resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history, history that includes the person's reported experiences, and reports of others familiar with the person. To be diagnosed with schizophrenia, symptoms and functional impairment need to be present for six months (DSM-5) or one month (ICD-11). Many people with schizophrenia have other mental disorders, especially substance use disorders, Mood disorder, depressive disorders, anxiety disorders, and obsessive–compulsive disorder. About 0.3% to 0.7% of p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trompe-l'œil
''Trompe-l'œil'' ( , ; ) is an artistic term for the highly realistic optical illusion of three-dimensional space and objects on a two-dimensional surface. ''Trompe l'oeil'', which is most often associated with painting, tricks the viewer into perceiving painted objects or spaces as real. Forced perspective is a related illusion in architecture. History in painting The phrase, which can also be spelled without the hyphen and ligature in English as ''trompe l'oeil'', originates with the artist Louis-Léopold Boilly, who used it as the title of a painting he exhibited in the Paris Salon of 1800. Although the term gained currency only in the early 19th century, the illusionistic technique associated with ''trompe-l'œil'' dates much further back. It was (and is) often employed in murals. Instances from Greek and Roman times are known, for instance in Pompeii. A typical ''trompe-l'œil'' mural might depict a window, door, or hallway, intended to suggest a larger room. A version o ...
