A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
Mechanicalanalog computers started appearing in the first century and were later used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications such as calculating torpedo aiming. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).
The term "computer", in use from the early 17th century (the first known written reference dates from 1613), meant "one who computes": a person performing mathematical calculations, before electronic computers became commercially available.
"The human computer is supposed to be following fixed rules; he has no authority to deviate from them in any detail." (Turing, 1950)
Teams of people were frequently used to undertake long and often tedious calculations; the work was divided so that this could be done in parallel.
The first time the term "Computer" appeared in The New York Times was February 3, 1853; an obituary stated:
Since the end of the 20th century, the term "human computer" has also been applied to individuals with prodigious powers of mental arithmetic, also known as mental calculators.
Much of the work on computer music has drawn on the relationship between music theory and mathematics, a relationship which has been noted since the Ancient Greeks described the "harmony of the spheres". The world's first computer to play music was CSIRAC, which was designed and built by Trevor Pearcey and Maston Beard in the 1950s. Mathematician Geoff Hill programmed the CSIRAC to play popular musical melodies from the very early 1950s. In 1951 it publicly played the "Colonel Bogey March" of which no known recordings exist.
However, CSIRAC played standard repertoire and was not used to extend musical thinking or composition practice which is current computer-music practice.
Physical medicine and rehabilitation (PM&R), also known as physiatry, a branch of medicine that aims to enhance and restore functional ability and quality of life to those with physical impairments or disabilities
Physical therapy, also known as physical rehabilitation or physiotherapy, treatments and exercises concerned with remediation of physical impairments and disabilities through promotion of mobility, functional ability, and quality of life
Aquatic therapy, treatments and exercises performed in water for relaxation, fitness, physical rehabilitation, and other therapeutic benefit
Medical nutrition therapy (MNT), a therapeutic approach to treating medical conditions and associated symptoms via specifically tailored diet
Physical exercise, bodily activity that enhances or maintains physical fitness and overall health and wellness
Sports medicine, a branch of medicine that focuses on physical fitness, as well as treatment and prevention of injuries related to sports and exercise
Athletic training, exercises and regimes to optimize performance and ability to participate in athletic activities
Fadil El Ghoul (born Breda, 2 April 1986), better known by his stage nameR3hab (pronounced "rehab"), is a Dutch DJ and record producer of Moroccan origin. Alongside Afrojack and Chuckie, R3hab is one of the proponents of the modern Dutch house subgenre, although his style and sound at the time were usually darker, somewhat reminiscent of early psytrance or gabber compositions. During the 2012 WMC in Miami, USA, R3hab won the IDMA Best Breakthrough Artist Award.
R3hab began his career in late 2007 while producing the track "Mrkrstft" with Hardwell. One of the main influences R3hab has listed is the duo Infected Mushroom, whose music has been on the international scene since 1999.
His most notable releases to date are "Pump The Party" produced together with Ferruccio Salvo, "The Bottle Song", released on Wall Recordings and "Prutataaa", which was R3hab’s first collaboration with Afrojack.
Rehab was originally formed as a trio: Denny Campbell (Steaknife), Danny (Boone) Alexander, and Jason Brooks (Brooks Buford). Danny Boone and Steaknife, both from Warner Robins, Georgia, were the rap group "Prime Suspect"
Danny Boone and Brooks Buford, both recovering alcoholics and drug addicts. It is a common misbelief that they met at a rehab facility. The trio formed Rehab, literally a product of their namesake.
Early on, they released their first album To Whom It May Consume produced by Steaknife and Brooks Buford. Soon after, Epic/Sony offered a record deal. Shortly before the record deal, Steaknife was incarcerated and the group continued on as a duo. Mashing rap with rock, the duo released their major label debut album, Southern Discomfort, in 2000 on the Sony label. Cee-Lo, Goodie Mob, and Cody ChesnuTT were some of the guests on the album, which would spawn the Top 15 modern rock hit "It Don't Matter." Two years were spent on the road supporting the album, including a stint on the Warped Tour, and then the duo splintered.
