IAAF Diamond League

The IAAF Diamond League is an annual series of track and field meetings held from 2010 onwards, beginning with the 2010 IAAF Diamond League. It was designed to replace the IAAF Golden League, which was held annually since 1998.

While the Golden League was formed to increase the profile of the leading European athletics competitions, the Diamond League's aim is to "enhance the worldwide appeal of athletics by going outside Europe for the first time." In addition to the original Golden League members (except Berlin) and other traditional European meetings, the series includes events in China, Qatar, and the United States.

Scoring system

Each one of the thirty-two disciplines (sixteen for male athletes, sixteen for females) is staged a total of seven times during the season. The top three athletes at each meeting are awarded points, and in the case of the Final meeting of the discipline the points are doubled.

1st place: 4 points; (Final: 8 points)
2nd place: 2 points; (Final: 4 points)
3rd place: 1 point; (Final: 2 points)

Rabat

Rabat (Arabic: ar-Ribaaṭ الرباط‎; Berber: ⴰⵕⴱⴰⵟ Aṛbaṭ) is the capital of Morocco and its seventh largest city center with an urban population of approximately 580,000 (2014) and a metropolitan population of over 1.2 million. It is also the capital of the Rabat-Salé-Kénitra administrative region.

The city is located on the Atlantic Ocean at the mouth of the river Bou Regreg. On the facing shore of the river lies Salé, the city's main commuter town. Rabat, Temara, and Salé form a conurbation of over 1.8 million people. Silt-related problems have diminished Rabat's role as a port; however, Rabat and Salé still maintain important textile, food processing and construction industries. In addition, tourism and the presence of all foreign embassies in Morocco serve to make Rabat one of the most important cities in the country.

Once a reputed corsair haven, Rabat served as one of the many ports in North Africa for the Barbary pirates, who were particularly active from the 16th through the 18th centuries.

Diamond

In mineralogy, diamond (/ˈdaɪəmənd/ or /ˈdaɪmənd/; from the ancient Greek ἀδάμας – adámas "unbreakable") is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.

Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).

Man

A man is a male human. The term man is usually reserved for an adult male, with the term boy being the usual term for a male child or adolescent. However, the term man is also sometimes used to identify a male human, regardless of age, as in phrases such as "men's basketball".

Like most other male mammals, a man's genome typically inherits an X chromosome from his mother and a Y chromosome from his father. The male fetus produces larger amounts of androgens and smaller amounts of estrogens than a female fetus. This difference in the relative amounts of these sex steroids is largely responsible for the physiological differences that distinguish men from women. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. However, there are exceptions to the above for some intersex and transgender men.

Etymology

The English term "man" is derived from a Proto-Indo-European root *man- (see Sanskrit/Avestan manu-, Slavic mǫž "man, male"). More directly, the word derives from Old English mann. The Old English form had a default meaning of "adult male" (which was the exclusive meaning of wer), though it could also signify a person of unspecified gender. The closely related Old English pronoun man was used just as it is in Modern German to designate "one" (e. g., in the saying man muss mit den Wölfen heulen). The Old English form is derived from Proto-Germanic *mannz, "human being, person", which is also the etymon of German Mann "man, husband" and man "one" (pronoun), Old Norse maðr, and Gothic manna. According to Tacitus, the mythological progenitor of the Germanic tribes was called Mannus. *Manus in Indo-European mythology was the first man, see Mannus, Manu (Hinduism).
