City

A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.

Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process, but it also presents challenges to managing urban growth.

A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis. In terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai.

Origins

There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.

Kontra

A kontra is a Hungarian (Hungarian: háromhúros brácsa, ‘three-stringed viola’), Romanian, Slovak and Romani instrument common in Transylvania.

Construction

The kontra is constructed much like the classical viola, with two major differences. First, there are only three strings instead of four. Second, the bridge is flattened, allowing a musician to play all three strings at once.

Tuning

The kontra is tuned like a viola, though lacking its low C string: G-D-A.

Technique

Due to the flattened bridge, a kontra is not as capable of playing melody lines as a viola. Rather, the standard method of play is to play double stops and three-note chords and let the fiddle play melody lines.

Ensemble Playing

The kontra has a defined role within dance band music. Its range lies between that of the fiddle or Vioara cu goarnă on the high-end and the double bass on the low-end. Many Romanian and Hungarian bands also feature the cimbalom or citera, clarinet, accordion, and Ütőgardon or cello.

Manchester City F.C.

Manchester City Football Club is a football club in Manchester, England. Founded in 1880 as St. Mark's (West Gorton), they became Ardwick Association Football Club in 1887 and Manchester City in 1894. The club moved to the City of Manchester Stadium in 2003, having played at Maine Road since 1923.

The club's most successful period was in the late 1960s and early 1970s when they won the League Championship, FA Cup, League Cup and European Cup Winners' Cup under the management team of Joe Mercer and Malcolm Allison. After losing the 1981 FA Cup Final, the club went through a period of decline, culminating in relegation to the third tier of English football for the only time in their history in 1998.

Having regained Premier League status, the club was purchased in 2008 by Abu Dhabi United Group and has become one of the wealthiest in the world. In 2011, Manchester City qualified for the UEFA Champions League and won the FA Cup. The following year, they won the Premier League, their first league title for 44 years. In 2014, they won the League Cup and a second Premier League title.

Mathematical fallacy

In mathematics, certain kinds of mistaken proof are often exhibited, and sometimes collected, as illustrations of a concept of mathematical fallacy. There is a distinction between a simple mistake and a mathematical fallacy in a proof: a mistake in a proof leads to an invalid proof just in the same way, but in the best-known examples of mathematical fallacies, there is some concealment in the presentation of the proof. For example, the reason validity fails may be a division by zero that is hidden by algebraic notation. There is a striking quality of the mathematical fallacy: as typically presented, it leads not only to an absurd result, but does so in a crafty or clever way. Therefore, these fallacies, for pedagogic reasons, usually take the form of spurious proofs of obvious contradictions. Although the proofs are flawed, the errors, usually by design, are comparatively subtle, or designed to show that certain steps are conditional, and should not be applied in the cases that are the exceptions to the rules.
