Cymatics
Cymatics (from grc, κῦμα, translit=kyma, translation=wave) is a subset of modal vibrational phenomena. The term was coined by Hans Jenny (1904-1972), a Swiss follower of the philosophical school known as anthroposophy. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency. The apparatus employed can be simple, such as the Chinese spouting bowl, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Other examples include the Chladni Plate and the so-called cymascope. History On July 8, 1680, Robert Hooke was able to see the nodal patterns associated with the modes of vibration of glass plates. Hooke ran a bow along the edge of a glass plate covered with flour, and saw the nodal patterns emerge. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Lauterwasser
Alexander Lauterwasser (born 1951 in Überlingen) is a German researcher and photographer who based his work on work done by Ernst Chladni and Hans Jenny in the field of Cymatics. In 2002, Lauterwasser published his book ''Wasser Klang Bilder'' (Water Sound Images) with imagery of water surfaces set into motion by sound sources ranging from pure sine waves to music by Ludwig van Beethoven, Karlheinz Stockhausen and even overtone chanting. In 2006, MACROmedia Publishing published the English version of the Lauterwasser book titled ''Water Sound Images''. It is a 176-page hardcover edition with hundreds of color photos, presenting the art, science and mystical side of Cymatics. In 2012, Lauterwasser's work was featured in the film Inner Worlds Outer Worlds ''Inner Worlds, Outer Worlds'' is a documentary film created by Canadian film maker and meditation teacher Daniel Schmidt. The film was released in 2012. The film was released for free online. It has been narrated in E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Chladni
Ernst Florens Friedrich Chladni (, , ; 30 November 1756 – 3 April 1827) was a German physicist and musician. His most important work, for which he is sometimes labeled as the father of acoustics, included research on vibrating plates and the calculation of the speed of sound for different gases. He also undertook pioneering work in the study of meteorites and is regarded by some as the father of meteoritics. Early life Although Chladni was born in Wittenberg in Saxony, his family originated from Kremnica, then part of the Kingdom of Hungary and today a mining town in central Slovakia. Chladni has therefore been identified as German, Hungarian and Slovak. Chladni came from an educated family of academics and learned men. Chladni's great-grandfather, the Lutheran clergyman Georg Chladni (1637–1692), had left Kremnica in 1673 during the Counter Reformation. Chladni's grandfather, Martin Chladni (1669–1725), was also a Lutheran theologian and, in 1710, became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Jenny (cymatics)
Hans Jenny (16 August 1904, Basel – 23 June 1972, Dornach) was a physician and natural scientist who coined the term cymatics to describe acoustic effects of sound wave phenomena. Life and career Jenny was born in Basel, Switzerland. After completing a doctorate he taught science at the Rudolph Steiner School in Zürich for four years before beginning medical practice. In 1967, Jenny published the first volume of ''Cymatics: The Study of Wave Phenomena.'' The second volume came out in 1972, the year he died. This book was a written and photographic documentation of the effects of sound vibrations on fluids, powders and liquid paste. He concluded, "This is not an unregulated chaos; it is a dynamic but ordered pattern." Jenny made use of crystal oscillators and his so-called tonoscope to set plates and membranes vibrating. He spread quartz sand onto a black drum membrane 60 cm in diameter. The membrane was caused to vibrate by singing loudly through a cardboard pipe, and ...

Standing Bell
A standing bell or resting bell is an inverted bell, supported from below with the rim uppermost. Such bells are normally bowl-shaped, and exist in a wide range of sizes, from a few centimetres to a metre in diameter. They are often played by striking, but some—known as singing bowls—may also be played by rotating a mallet around the outside rim to produce a sustained musical note. Struck bowls are used in some Buddhist religious practices to accompany periods of meditation and chanting. Struck and singing bowls are widely used for music making, meditation and relaxation, as well for personal spirituality. They have become popular with music therapists, sound healers and yoga practitioners. Standing bells originated in China. An early form called took the shape of a stemmed goblet, mounted with rim uppermost, and struck on the outside with a mallet. The manufacture and use of bowls specifically for 'singing' is believed to be a modern phenomenon. Bowls that were capable o ...

Ron Rocco
Ron Rocco (born 1953, Texas, U.S) is an American artist who has worked in New York City, Rotterdam in the Netherlands, Berlin, Germany and China. His work entails performance, mixed media installations and sculptural constructions employing a mix of found objects and prepared elements. Early life and education As a child Ron Rocco traveled with his parents to Germany, where his father served as an American soldier in the post-war occupation army. The artist attributed his early experience with German culture as a defining element in the background to his interest in Europe and his sometimes social and political themes. In the late 1950s and '60s Rocco grew up in the Bronx in New York City. His was an ethnically Italian neighborhood, surrounding Arthur Avenue, known as the Little Italy of the Bronx. The neighborhood scrap metal yards, inspired an early interest in working with metals, and a sense of the latent potential of found materials to evoke memory and associations. Rocco ...

Center For Advanced Visual Studies
The MIT Program in Art, Culture and Technology (ACT) has its origins in the Center for Advanced Visual Studies (CAVS) at the Massachusetts Institute of Technology (MIT), an arts and research center founded in 1967 by artist and teacher György Kepes. In 2009, CAVS merged with the MIT Visual Arts Program, to become the MIT Program in Art, Culture and Technology (ACT). The Program is part of the MIT School of Architecture and Planning. History György Kepes, who taught at the New Bauhaus (now the IIT Institute of Design in Chicago), founded the Center at MIT as a way to encourage artistic collaboration on a large civic scale. During its 45-year existence, the CAVS hosted more than 200 artists and fellows that "pioneered collaborative works in light, kinetic, environmental and inflatable sculpture, laser, steam, video, electronic music, holography, dance, computer graphics and animation, among other media". In 1974, Otto Piene succeeded Kepes as the director of the CAVS. Piene retir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
György Kepes
György Kepes �ɟøɾɟ ˈkɛpɛʃ(October 4, 1906 – December 29, 2001) was a Hungarian-born painter, photographer, designer, educator, and art theorist. After immigrating to the U.S. in 1937, he taught design at the New Bauhaus (later the School of Design, then Institute of Design, then Illinois Institute of Design or IIT) in Chicago. In 1967 he founded the Center for Advanced Visual Studies at the Massachusetts Institute of Technology (MIT) where he taught until his retirement in 1974. Early years Kepes was born in Selyp, Hungary. His younger brother was Imre Kepes, ambassador in Argentina, father of András Kepes, a journalist, documentary filmmaker and author. At age 18, he enrolled at the Royal Academy of Fine Arts in Budapest, where he studied for four years with Istvan Csok, a Hungarian impressionist painter.

Sheet Metal
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous ( iron-based) metals and nonferrous metals such as aluminum or copper. Co ...

Thermodynamic
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resonance Chladni Soundboard Harpsichord Clavecin
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system. Small periodic forces that are near a resonant frequency of the system have the ability to produce large amplitude oscillations in the system due to the storage of vibrational energy. Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, orbital resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and ...

Servo Motor
A servomotor (or servo motor) is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors. Servomotors are not a specific class of motor, although the term ''servomotor'' is often used to refer to a motor suitable for use in a closed-loop control system. Servomotors are used in applications such as robotics, CNC machinery, and automated manufacturing. Mechanism A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position commanded for the output shaft. The motor is paired with some type of position encoder to provide position and speed feedback. In the simples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Hykes
David Hykes (born March 2, 1953, Taos, New Mexico) is a composer, singer, musician, author, and meditation teacher. He was one of the earliest modern western pioneers of overtone singing, and since 1975 has developed a comprehensive approach to contemplative music which he calls Harmonic Chant (harmonic singing). After early research and trips studying Mongolian, Tibetan, and Middle Eastern singing forms, Hykes began a long series of collaborations with traditions and teachers of wisdom and sacred art, including the Dalai Lama and the Gyuto and Gyume monks. Hykes founded the Harmonic Choir in 1975, and has performed and taught Harmonic Chant and the related Harmonic Presence work in America, France, Germany, Italy, Switzerland, Japan, Australia and many other countries. Of overtone singing and his own study of the form, music theorist Charles Madden writes, "David Hykes has done everything I had hoped to do, and more." His choir incorporates both basic overtone singing as well as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
