Data

Data (/ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").

Zen

Zen (Chinese: 禪; pinyin: Chán, Middle Chinese: dʑjen) is a school of Mahayana Buddhism that originated in China during the Tang dynasty as Chán. It was strongly influenced by Taoism, and developed as a distinguished Chinese style of Buddhism. From China, Chán spread south to Vietnam, northeast to Korea and east to Japan, where it became known as Japanese Zen.

Zen emphasizes rigorous meditation-practice, insight into Buddha-nature, and the personal expression of this insight in daily life, especially for the benefit of others. As such, it de-emphasizes mere knowledge of sutras and doctrine and favors direct understanding through zazen and interaction with an accomplished teacher.

The teachings of Zen include various sources of Mahāyāna thought, especially Yogācāra, the Tathāgatagarbha Sutras and Huayan, with their emphasis on Buddha-nature, totality, and the Bodhisattva-ideal. The Prajñāpāramitā literature and, to a lesser extent, Madhyamaka have also been influential in the shaping of the "paradoxical language" of the Zen-tradition.

Island

An island /ˈaɪlənd/ or isle /ˈaɪl/ is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, or a holm. A grouping of geographically or geologically related islands is called an archipelago, e.g. the Philippines.

An island may be described as such despite the presence of an artificial land bridge, for example Singapore and its causeway, or the various Dutch delta islands, such as IJsselmonde. Some places may even retain "island" in their names for historical reasons after being connected to a larger landmass by a wide land bridge, such as Coney Island or Coronado Island. Conversely, when a piece of land is separated from the mainland by a man-made canal, for example the Peloponnese by the Corinth Canal, it is generally not considered an island.

There are two main types of islands: continental islands and oceanic islands. There are also artificial islands.

Peter Tosh

Peter Tosh, OM (born Winston Hubert McIntosh; 19 October 1944 – 11 September 1987) was a Jamaican reggae musician. Along with Bob Marley and Bunny Wailer he was one of the core members of the band The Wailers (1963–1974), after which he established himself as a successful solo artist and a promoter of Rastafari. He was murdered in 1987 during a home invasion.

Early music and with The Wailers

Tosh was born in Westmoreland Jamaica,the nation's westernmost parish. When McIntosh was fifteen, his aunt died and he moved to Trench Town in Kingston, Jamaica. He first picked up a guitar by watching a man in the country play a song that captivated him. He watched the man play the same song for half a day, memorizing everything his fingers were doing. He then picked up the guitar and played the song back to the man. The man then asked McIntosh who had taught him to play; McIntosh told him that he had. During the early 1960s Tosh met Robert Nesta Marley (Bob Marley) and Neville O'Reilly Livingston (Bunny Wailer) and went to vocal teacher Joe Higgs, who gave out free vocal lessons to young people, in hopes to form a new band. He then changed his name to become Peter Tosh and the trio started singing together in 1962. Higgs taught the trio to harmonize and while developing their music, they would often play on the street corners of Trenchtown.

Music

Music is an art form and cultural activity whose medium is sound and silence. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."
