Electronic music

Electronic music is music that employs electronic musical instruments and electronic music technology in its production, an electronic musician being a musician who composes and/or performs such music. In general a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer.

The first electronic devices for performing music were developed at the end of the 19th century, and shortly afterward Italian Futurists explored sounds that had previously not been considered musical. During the 1920s and 1930s, electronic instruments were introduced and the first compositions for electronic instruments were composed. By the 1940s, magnetic audio tape allowed musicians to tape sounds and then modify them by changing the tape speed or direction, leading to the development of electroacoustic tape music in the 1940s, in Egypt and France. Musique concrète, created in Paris in 1948, was based on editing together recorded fragments of natural and industrial sounds. Music produced solely from electronic generators was first produced in Germany in 1953. Electronic music was also created in Japan and the United States beginning in the 1950s. An important new development was the advent of computers for the purpose of composing music. Algorithmic composition was first demonstrated in Australia in 1951.

Electronic (band)

Electronic were an English alternative dance supergroup formed by New Order singer and guitarist Bernard Sumner and ex-Smiths guitarist Johnny Marr. They co-wrote the majority of their output between 1989 and 1998, collaborating with Neil Tennant and Chris Lowe, of Pet Shop Boys, on three tracks in their early years, and former Kraftwerk member Karl Bartos on nine songs in 1995.

History

The two first met in 1984 when the Smiths guitarist contributed to a Quando Quango track that Sumner was producing. Later in 1988, Sumner was frustrated because his New Order bandmates were not receptive to his desire to add synth programming to their music. He decided to produce a solo album but found that he did not enjoy working alone, so he called Marr for help.

Inspired by contemporary dance music like Italo house and acts such as Technotronic, their initial concept was to release white label records on Factory and remain an anonymous entity, in contrast to their considerable reputations with The Smiths and New Order. The track "Lucky Bag" and the name Electronic itself are two of the vestiges of this initial approach. In 1989, Pet Shop Boys singer Neil Tennant suggested a collaboration when he heard of the budding partnership through sleeve designer Mark Farrow .

Private (rocket)

Private was an experimental rocket developed by the California Institute of Technology on behalf of the United States Army. Tested in two different configurations, it provided the proof of concept that a fin-stabilised ballistic missile was technologically feasible, and led to the development of the Corporal ballistic missile.

History

The Private program was begun in 1944 as an outgrowth of work by the California Institute of Technology's Guggenheim Aeronautical Laboratory that had produced the first practical jet-assisted take-off (JATO) rockets. A proposal to adapt the JATO rockets for research into the development of ballistic missiles was accepted, and the first flight of the Private A rocket, developed under the direction of Tsien Hsue-shen, took place in December 1944, conducted at Camp Irwin in California.

Private A was an unguided, fin-stabilised ballistic rocket; it consisted of a JATO unit equipped with cruciform tail fins, and a set of four T22 booster rockets that were jettisoned after launch. This made Private A the first multistage rocket to be flown in the United States.

Information hiding

In computer science, information hiding is the principle of segregation of the design decisions in a computer program that are most likely to change, thus protecting other parts of the program from extensive modification if the design decision is changed. The protection involves providing a stable interface which protects the remainder of the program from the implementation (the details that are most likely to change).

Written another way, information hiding is the ability to prevent certain aspects of a class or software component from being accessible to its clients, using either programming language features (like private variables) or an explicit exporting policy.

Overview

The term encapsulation is often used interchangeably with information hiding. Not all agree on the distinctions between the two though; one may think of information hiding as being the principle and encapsulation being the technique. A software module hides information by encapsulating the information into a module or other construct which presents an interface.
