Nun (letter)

Nun is the fourteenth letter of the Semitic abjads, including Phoenician Nūn , Hebrew Nun נ, Aramaic Nun , Syriac Nūn ܢܢ, and Arabic Nūn ن (in abjadi order). It is the third letter in Thaana (ނ), pronounced as "noonu".
Its sound value is [n].

The Phoenician letter gave rise to the Greek nu (Ν), Etruscan , Latin N, and Cyrillic Н.

Origins

Nun is believed to be derived from an Egyptian hieroglyph of a snake (the Hebrew word for snake, nachash begins with a Nun and snake in Aramaic is nun) or eel. Some have hypothesized a hieroglyph of fish in water as its origin (in Arabic, nūn means large fish or whale). The Phoenician letter was named nūn "fish", but the glyph has been suggested to descend from a hypothetical Proto-Canaanite naḥš "snake", based on the name in Ethiopic, ultimately from a hieroglyph representing a snake,

(see Middle Bronze Age alphabets). Naḥš in modern Arabic literally means "bad luck". The cognate letter in Ge'ez and descended Semitic languages of Ethiopia is nehas, which also means "brass".

Nun (biblical figure)

Nun /ˈnʊn/, in the Hebrew Bible, was a man from the Tribe of Ephraim, grandson of Ammihud, son of Elishama, and father of Joshua. (1 Chronicles 7:26-27) He grew up in and may have lived his entire life in the Israelites' Egyptian captivity, where the Egyptians "made life bitter for them with harsh labor at mortar and bricks and with all sorts of tasks in the field." (Exodus 1:14) In Aramaic, "nun" means "fish". Thus the Midrash tells: "[T]he son of him whose name was as the name of a fish would lead them [the Israelites] into the land." (Genesis Rabba 97:3.)

Tradition places Nun's tomb near that of his son Joshua who, according to Joshua 24:30, is buried in Timnat Serah whereas in Judges 2:9 it is mentioned as Timnath-heres.. The similarly named Palestinian village of Kifl Hares/Timnat Hares, located northwest of Ariel in the Samarian region of the West Bank, now encircles both tombs.

Oxynoemacheilus galilaeus

Oxynoemacheilus galilaeus is a species of stone loach in the Nemacheilidae family native to Israel and Syria. Its natural habitats are swamps and freshwater lakes. It is threatened by habitat loss.

Racewalking

Racewalking, or race walking, is a long-distance discipline within the sport of athletics. Although it is a foot race, it is different from running in that one foot must appear to be in contact with the ground at all times. This is assessed by race judges, making it the most subjective of the disciplines in athletics. Typically held on either roads or on running tracks, common distances vary from 3000 metres (1.8 mi) up to 100 kilometres (62.1 mi).

There are two racewalking distances contested at the Summer Olympics: the 20 kilometres race walk (men and women) and 50 kilometres race walk (men only). Both are held as road events. The biennial IAAF World Championships in Athletics also features the same three events. The IAAF World Race Walking Cup, first held in 1961, is a stand-alone global competition for the discipline and it has 10 kilometres race walks for junior athletes, in addition to the Olympic-standard events. The IAAF World Indoor Championships featured 5000 m and 3000 m race walk variations, but these were discontinued after 1993. Top level athletics championships and games typically feature 20 km racewalking events.

Glossary of cricket terms

This is a general glossary of the terminology used in the sport of cricket. Where words in a sentence are also defined elsewhere in this article, they appear in italics. Certain aspects of cricket terminology are explained in more detail in cricket statistics and the naming of fielding positions is explained at fielding (cricket).

Cricket is known for its rich terminology. Some terms are often thought to be arcane and humorous by those not familiar with the game.

Traveling (basketball)

In basketball, traveling (travelling in Commonwealth English) is a violation of the rules that occurs when a player holding the ball moves one or both of their feet illegally. Most commonly, a player travels by illegally moving his or her pivot foot or taking two or more steps without dribbling the ball. A similar rule with the same name exists in the related sports of netball and korfball.

Traveling is someyimes also called "walking", "steps", "deucing", or "carrying," predominantly in a streetball atmosphere.

NCAA

Section 72. Traveling

Art. 1. A player who catches the ball with both feet on the playing court may pivot, using either foot. When one foot is lifted, the other is the pivot foot.

Art. 2. A player who catches the ball while moving or dribbling may stop and establish a pivot foot as follows:

Art. 3. After coming to a stop and establishing the pivot foot:

Art. 4. After coming to a stop when neither foot can be the pivot foot:

Art. 5. It is traveling when a player falls to the playing court while holding the ball without maintaining a pivot foot.

Fence (mathematics)

In mathematics, a fence, also called a zigzag poset, is a partially ordered set in which the order relations form a path with alternating orientations:

or

A fence may be finite, or it may be formed by an infinite alternating sequence extending in both directions. The incidence posets of path graphs form examples of fences.

A linear extension of a fence is called an alternating permutation; André's problem of counting the number of different linear extensions has been studied since the 19th century. The solutions to this counting problem, the so-called Euler zigzag numbers or up/down numbers, are

The number of antichains in a fence is a Fibonacci number; the distributive lattice with this many elements, generated from a fence via Birkhoff's representation theorem, has as its graph the Fibonacci cube.

A partially ordered set is series-parallel if and only if it does not have four elements forming a fence.

Several authors have also investigated the number of order-preserving maps from fences to themselves, or to fences of other sizes.
