Information: - Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word "tungsten" comes from the Swedish language "tung sten", which directly translates to "heavy stone". Its name in Swedish is "volfram", however, in order to distinguish it from scheelite, which is alternatively named "tungsten" in Swedish. - Tungstic acid refers to hydrated forms of tungsten trioxide , WO3 . The simplest form , the monohydrate , is WO3 - Tungsten(VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO, is a chemical compound containing oxygen and the transition metal tungsten. It is obtained as an intermediate in the recovery of tungsten from its minerals. Tungsten ores are treated with alkalis to produce WO. Further reaction with carbon or hydrogen gas reduces tungsten trioxide to the pure metal. - Hydrogen is a chemical element with chemical symbolH and atomic number1. With an atomic weight of , hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most common isotope of hydrogen, termed "protium" (name rarely used, symbol H), has one proton and no neutrons. - In chemistry, an alkali (from Arabic: "al-qaly" , , ashes of the saltwort) is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline is commonly, and alkalescent less often, used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. - Oxygen is a chemical element with symbolO and atomic number8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . This is an important part of the atmosphere and diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. Additionally, as oxides the element makes up almost half of the Earth's crust. - Carbon (from "coal") is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bonds. Three isotopes occur naturally, C and C being stable, while C is a radioactive isotope, decaying with a half-life of about 5,730years. Carbon is one of the few elements known since antiquity.

Information: - Jon Ivar Christensen (born 20 March 1943 in Oslo, Norway) is a Norwegian jazz drummer. He is married to actress, minister, and theater director Ellen Horn , and is the father of singer and actress Emilie Stoesen Christensen. - Jan Garbarek (born 4 March 1947) is a Norwegian jazz saxophonist who is also active in classical music and world music. - Photo with Blue Sky , White Cloud , Wires , Windows and a Red Roof is an album by Norwegian saxophonist Jan Garbarek , released in 1979 on the ECM label and performed by Garbarek , John Taylor , Bill Connors , Eberhard Weber and Jon Christensen . - Oslo is the capital and the most populous city in Norway. It constitutes both a county and a municipality. Founded in the year 1040, and established as a "kaupstad" or trading place in 1048 by Harald Hardrada, the city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 and with Sweden from 1814 to 1905 reduced its influence. After being destroyed by a fire in 1624, the city was moved closer to Akershus Fortress during the reign of Christian IV of Denmark and renamed Christiania in his honour. It was established as a municipality ("formannskapsdistrikt") on 1 January 1838. Following a spelling reform, it was known as Kristiania from 1877 to 1925, at which time its original Norwegian name was restored. - Return to Forever is a jazz fusion group founded and led by pianist Chick Corea. Through its existence, the band has had many members, with the only consistent bandmate of Corea's being bassist Stanley Clarke. Along with Weather Report and Mahavishnu Orchestra, Return to Forever is often cited as one of the core groups of the jazz-fusion movement of the 1970s. Several musicians, including Clarke, Flora Purim, Airto Moreira and Al Di Meola, first came to prominence through their performances on Return to Forever's albums. - Chamber jazz is a genre of jazz involving small, acoustic-based ensembles where group interplay is important. It is influenced aesthetically by musical neoclassicism and is often influenced by classical forms of Western music as well as non-Western music or culture. That stated, in many cases the influence is traditional Celtic music, , or Latin American music instead. The genre primarily began in Europe so significant neoclassical composers of Europe, like Igor Stravinsky, are important in it. The German ECM Records also played a role in it beginning in the late 1960s. It is also noted for using instruments not normally associated with jazz. For example, chamber jazz will make use of the oboe, mandolin, cymbalum, or the tabla. - Bill Connors (born September 24, 1949) is an American jazz guitarist who was a member of Chick Corea's band Return to Forever. After leaving Return to Forever, he recorded three acoustic albums and then three electric albums as a leader/soloist. - Eberhard Weber (born 22 January 1940 in Stuttgart) is a German double bassist and composer. As a bass player, he is known for his highly distinctive tone and phrasing. Weber's compositions blend chamber jazz, European classical music, minimalism and ambient music, and are regarded as characteristic examples of the ECM Records sound.
