Kemal, Yaşar or Yashar, 1922-, Turkish novelist, b. Kemal Sadik Gögçeli. His rural childhood was marked by poverty and trauma; at a mosque at age five he witnessed his father's murder and was blinded in one eye. Dropping out of secondary school, Kemal worked at various menial jobs, and, after settling in Istanbul, became (1951-63) a newspaper reporter and columnist. His debut novel, Memed My Hawk (1955, tr. 1961, film 1987), the first of a series (1969-87), is the tale of a Robin Hood-like Anatolian outlaw and a chronicle of peasant-landowner struggles. It became one of Turkey's most celebrated novels and earned him an international reputation. Mingling realism with fantasy and folklore, Kemal is a prolific and highly political storyteller who concentrates on tales of rural Anatolia. His other novels include The Wind from the Plain (1960, tr. 1963), Iron Earth, Copper Sky (1963, tr. 1974), The Undying Grass (1968, tr. 1977), Seagull (1976, tr. 1981), and Salman the Solitary (1998). He is also known for his short stories and essays. A leftist of Kurdish ancestry, Kemal was arrested several times for political activities and in 1995 was jailed following publication, in Germany, of an article condemning Turkey's oppression of its minority Kurds.

Harun ar-Rashid [Arab.,=Aaron the Upright], c.764-809, 5th and most famous Abbasid caliph (786-809). He succeeded his brother Musa al-Hadi, fourth caliph, a year after the death of his father, Mahdi, the third caliph. In his youth he had been very successful as a general in invasions of Asia Minor; on one of these he reached the Bosporus. Harun's empire included all SW Asia and the northern part of Africa, but by the end of his caliphate much of Africa had withdrawn from all but nominal obedience. He had diplomatic relations with China and with Charlemagne. The most famous incident of his career was the fall of the Barmakids, a Persian family that had become very powerful under Mahdi. Yahya, a Barmakid, had aided Harun in obtaining the caliphate, and he and his sons were in high favor until 798, when the caliph threw them in prison and confiscated their land; the reasons for this are not known, but it was probably a result of an extended intrigue by the Arab group at court. Harun was repeatedly faced with insurrections in his empire. These grew more frequent after the fall of the Barmakids, who were adroit statesmen. After this Harun's prime minister was Fazl ibn-Rabi. Harun was a munificent patron of letters and of arts, and under him Baghdad was at its apogee. He became a great figure to the Arabs, who tell about him in many of the stories of the Thousand and One Nights.

(born March 763 or February 766, Rayy, Iran—died March 24, 809, Tsubdotūs, Iran) Fifth caliph of the aynAbbāsid dynasty. Neither a great ruler nor a prepossessing character, Hārūn ruled (786–809) at a time when Islamic society reached its zenith in terms of wealth, learning, and power. He is best remembered, however, as a central character in The Thousand and One Nights, where he is portrayed as the epitome of the learned and just ruler. In his early years he was strongly influenced by his mother and by his tutor Yahsubdotyā of the Barmakid line of viziers. He succeeded his brother after the latter's untimely death and ruled over a realm that was torn increasingly by strife, as regional leaders sought autonomy. On his death, his sons al-Mahamzahmun and al-Amīn fell into open civil war.

Method for determining the age of igneous rocks based on the amount of argon-40 in the rock. Radioactive potassium-40 decays to argon-40 with a half-life of about 1.3 billion years, making this method useful for dating rocks that are billions of years old. A more sophisticated method, called argon-argon dating, provides a more accurate estimate of the original potassium-40 content by means of the ratio of argon-40 to argon-39 in the rock, thus yielding a more accurate age determination. Seealso dating.

Chemical element, chemical symbol Ar, atomic number 18. Colourless, odourless, and tasteless, it is the most abundant of the noble gases on Earth and the one most used in industry. It constitutes about 1percnt of air and is obtained by distillation of liquid air. Argon provides an inert gas shield in welding and brazing, in lightbulbs and lasers, in Geiger counters, and in the production and fabrication of certain metals. Because a radioactive form of argon is produced by decay of a naturally occurring radioactive potassium isotope, it can be used to date rocks and samples more than 100,000 years old.
