Gauss (crater)
Gauss is a large lunar crater, named after Carl Friedrich Gauss, that is located near the northeastern limb of the Moon's near side. It belongs to a category of lunar formations called a walled plain, meaning that it has a diameter of at least 110 kilometers, with a somewhat sunken floor and little or no central massif. Due to its location, this crater appears considerably foreshortened when viewed from the Earth, and its visibility is affected by libration.
To the northeast of Gauss is Riemann, another walled plain that lies even closer to the limb. Southwest of Gauss is the crater pair of Hahn and Berosus. Almost directly southward is Seneca.
The rim of Gauss is better formed in the northern half, and the inner walls have some terracing along the northwest and appear slumped in the northeast. The southern half of the rim is somewhat more eroded.
The interior floor is fairly flat in places, with several craters marking the surface in the southern half. There is also a small crater, Gauss B, lying along the interior of the eastern rim, with the smaller Gauss A lying across the rim just to the northeast of Gauss B. The floor of Gauss is also marked by several clefts, particularly along the eastern and northwestern edges. The uneven crater rims in the south and a series of rises in the north gives the appearance of a ridge line that traverses the crater floor from north to south.
Carl Friedrich Gauss
Johann Carl Friedrich Gauss (/ɡaʊs/; German: Gauß, pronounced [ɡaʊs]; Latin: Carolus Fridericus Gauss) (30 April 1777 – 23 February 1855) was a German mathematician who contributed significantly to many fields, including number theory, algebra, statistics, analysis, differential geometry, geodesy, geophysics, mechanics, electrostatics, astronomy, matrix theory, and optics.
Sometimes referred to as the Princeps mathematicorum (Latin, "the foremost of mathematicians") and "greatest mathematician since antiquity", Gauss had an exceptional influence in many fields of mathematics and science and is ranked as one of history's most influential mathematicians.
Early years
Carl Friedrich Gauss was born on 30 April 1777 in Brunswick (Braunschweig), in the Duchy of Brunswick-Wolfenbüttel (now part of Lower Saxony, Germany), as the son of poor working-class parents. His mother was illiterate and never recorded the date of his birth, remembering only that he had been born on a Wednesday, eight days before the Feast of the Ascension, which itself occurs 39 days after Easter. Gauss later solved this puzzle about his birthdate in the context of finding the date of Easter, deriving methods to compute the date in both past and future years. He was christened and confirmed in a church near the school he attended as a child.
Gauss (surname)
Gauss is a surname. Notable people with the surname include:
Gauss (unit)
The gauss, abbreviated as G or Gs, is the Gaussian units|cgs unit of measurement of a magnetic field B, which is also known as the "magnetic flux density" or the "magnetic induction". It is named after German mathematician and physicist Carl Friedrich Gauss.One gauss is defined as one maxwell unit per square(centimeter). The cgs system has been formally superseded by the International System of Units ISI system, which uses the Tesla (unit T)as the unit for B. One gauss equals 1×10−4 Tesla unit (100 μT ) I.e (1 T = val 10000 u=G)
Unit name and convention
As with all units whose names are derived from a person's name, the first letter of its symbol is uppercase ("G"), but when the unit is spelled out, it should always be written in lowercase ("gauss"), unless it begins a sentence.
Unit conversions
According to the system of Gaussian units (cgs), the gauss is the unit of magnetic flux density B and the equivalent of esu/cm2, while the oersted is the unit of magnetizing field H. One tesla is equal to 104 gauss, and one ampere per meter is equal to 4π × 10−3 oersted.

Crater (Aden)
Crater (/ˈkreɪtər/; Arabic: كريتر, [ˈkɾeːtəɾ]), also Kraytar, is a district of the Aden Governorate, Yemen. Its official name is Seera (Arabic: صيرة Ṣīrah). It is situated in a crater of an ancient volcano which forms the Shamsan Mountains. In 1991, the population was 70,319. As of 2003, the district had a population of 76,723 people.
In the closing days of British rule in 1967, Crater District became the focus of the Aden Emergency, sometimes called the last imperial war. After a mutiny of hundreds of soldiers in the South Arabian Federation Army on 20 June, all British forces withdrew from the Crater. The Crater was occupied by Arab fighters while British forces blocked off its two main entrances. In July, a British infantry battalion, led by Lt. Col. Colin Mitchell of the Argyll & Sutherland Highlanders, entered the Crater and managed to occupy the entire district overnight with no casualties. Nevertheless, deadly guerrilla attacks soon resumed, with the British leaving Aden by the end of November 1967, earlier than had been planned by British Prime Minister Harold Wilson and without an agreement on the succeeding governance.
Crater (Chinese astronomy)
According to traditional Chinese uranography, the modern constellation Crater is located within the southern quadrant of the sky, which is symbolized as the Vermilion Bird of the South (南方朱雀, Nán Fāng Zhū Què).
The name of the western constellation in modern Chinese is 巨爵座 (jù jué zuò), meaning "the huge wine holder constellation".
