John Chowning
John M. Chowning (; born August 22, 1934 in Salem, New Jersey) is an American composer, musician, discoverer, and professor best known for his work at Stanford University, the founding of CCRMA - Center for Computer Research in Music and Acoustics in 1975 and his development of the digital implementation of FM synthesis and the digital sound spatialization while there. Contribution Chowning is known for having developed the FM synthesis algorithm in 1967. In FM (frequency modulation) synthesis, both the carrier frequency and the modulation frequency are within the audio band. In essence, the amplitude and frequency of one waveform modulates the frequency of another waveform producing a resultant waveform that can be periodic or non-periodic depending upon the ratio of the two frequencies. Chowning's breakthrough allowed for simple—in terms of process—yet rich sounding timbres, which synthesized 'metal striking' or 'bell like' sounds, and which seemed incredibly simila ...

Biotechnology
Biotechnology is the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts thereof and molecular analogues for products and services. The term ''biotechnology'' was first used by Károly Ereky in 1919, meaning the production of products from raw materials with the aid of living organisms. Definition The concept of biotechnology encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materi ...

Golden Ratio
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. Expressed algebraically, for quantities a and b with a > b > 0, where the Greek letter phi ( or \phi) denotes the golden ratio. The constant \varphi satisfies the quadratic equation \varphi^2 = \varphi + 1 and is an irrational number with a value of The golden ratio was called the extreme and mean ratio by Euclid, and the divine proportion by Luca Pacioli, and also goes by several other names. Mathematicians have studied the golden ratio's properties since antiquity. It is the ratio of a regular pentagon's diagonal to its side and thus appears in the construction of the dodecahedron and icosahedron. A golden rectangle—that is, a rectangle with an aspect ratio of \varphi—may be cut into a square and a smaller rectangle with the same aspect ratio. The golden ratio has been used to analyze the proportions of natural obj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stria (composition)
Stretch marks, also known as striae () or striae distensae, are a form of scarring on the skin with an off-color hue. Over time they may diminish, but will not disappear completely. Striae are caused by tearing of the dermis during periods of rapid growth of the body, such as during puberty or pregnancy, in which they usually form during the last trimester. Usually on the stomach, these striae also commonly occur on the breasts, thighs, hips, lower back, and buttocks. Pregnancy-related striae are known as ''striae gravidarum''. Striae may also be influenced by the hormonal changes associated with puberty, pregnancy, bodybuilding, or hormone replacement therapy. There is no evidence that creams used during pregnancy prevent stretch marks. Once they have formed there is no clearly effective treatment, though various methods have been attempted and studied. Signs and symptoms Striae, or "stretch marks", begin as reddish or purple lesions, which can appear anywhere on the body, ...

IRCAM
IRCAM (French: ''Ircam, '', English: Institute for Research and Coordination in Acoustics/Music) is a French institute dedicated to the research of music and sound, especially in the fields of avant garde and electro-acoustical art music. It is situated next to, and is organisationally linked with, the Centre Pompidou in Paris. The extension of the building was designed by Renzo Piano and Richard Rogers. Much of the institute is located underground, beneath the fountain to the east of the buildings. A centre for musical research Several concepts for electronic music and audio processing have emerged at IRCAM. John Chowning pioneered work on FM synthesis at IRCAM, and Miller Puckette originally wrote Max at IRCAM in the mid-1980s, which would become the real-time audio processing graphical programming environment Max/MSP. Max/MSP has subsequently become a widely used tool in electroacoustic music. Many of the techniques associated with spectralism, such as analyses based on ...

Nadia Boulanger
Juliette Nadia Boulanger (; 16 September 188722 October 1979) was a French music teacher and conductor. She taught many of the leading composers and musicians of the 20th century, and also performed occasionally as a pianist and organist. From a musical family, she achieved early honours as a student at the Conservatoire de Paris but, believing that she had no particular talent as a composer, she gave up writing music and became a teacher. In that capacity, she influenced generations of young composers, especially those from the United States and other English-speaking countries. Among her students were many important composers, soloists, arrangers, and conductors, including Grażyna Bacewicz, Burt Bacharach, Daniel Barenboim, Lennox Berkeley, İdil Biret, Elliott Carter, Aaron Copland, John Eliot Gardiner, Philip Glass, Roy Harris, Quincy Jones, Dinu Lipatti, Igor Markevitch, Astor Piazzolla, Virgil Thomson, and George Walker.

Wittenberg University is associated with the Evangelical Lutheran Church in America. History Wittenberg College (it became Wittenberg University in 1957) was founded in 1845 by a group of ministers in the English Evangelical Lutheran Synod of Ohio, which had previously separated from the recently established German-speaking Evangelical Lutheran Joint Synod of Ohio and Other States. A German American pastor of the Evangelical Lutheran Church, the Rev. Ezra Keller was the principal founder and first president of the college. Its initial focus was to train clergy with the Hamma School of Divinity as its theological department. One of its main missions was to "Americanize" Lutherans by teaching courses in the English language instead of German, unlike the nearby Capital University in Columbus, Ohio. The first class or ...
