Gun

A gun is a normally tubular weapon or other device designed to discharge projectiles or other material. The projectile may be solid, liquid, gas or energy and may be free, as with bullets and artillery shells, or captive as with Taser probes and whaling harpoons. The means of projection varies according to design but is usually effected by the action of gas pressure, either produced through the rapid combustion of a propellant or compressed and stored by mechanical means, operating on the projectile inside an open-ended tube in the fashion of a piston. The confined gas accelerates the movable projectile down the length of the tube, imparting sufficient velocity to sustain the projectile's travel once the action of the gas ceases at the end of the tube or muzzle. Alternatively, acceleration via electromagnetic field generation may be employed in which case the tube may be dispensed with and a guide rail substituted.

The first devices identified as guns appeared in China around CE 1000. By the 12th century the technology was spreading through the rest of Asia, and into Europe by the 13th century.

Monk

A monk (from Greek: μοναχός, monachos, "single, solitary" and Latin monachus) is a person who practices religious asceticism, living either alone or with any number of other monks. A monk may be a person who decided to dedicate his life to serving all other living beings, or to be an ascetic who voluntarily chooses to leave mainstream society and live his life in prayer and contemplation. The concept is ancient and can be seen in many religions and in philosophy.

In the Greek language the term can apply to women, but in modern English it is mainly in use for men. The word nun is typically used for female monastics.

Although the term monachos is of Christian origin, in the English language "monk" tends to be used loosely also for both male and female ascetics from other religious or philosophical backgrounds. However, being generic, it is not interchangeable with terms that denote particular kinds of monk, such as friar, cenobite, hermit, anchorite, hesychast, or solitary.

Map

A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes.

Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale; e.g. brain mapping, DNA mapping and extraterrestrial mapping.

Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the medieval Latin Mappa mundi, wherein mappa meant napkin or cloth and mundi the world. Thus, "map" became the shortened term referring to a two-dimensional representation of the surface of the world.

Geographic maps

Cartography or map-making is the study and practice of crafting representations of the Earth upon a flat surface (see History of cartography), and one who makes maps is called a cartographer.

Age of Empires

Age of Empires is a series of personal computer games developed by Ensemble Studios and published by Microsoft Studios. The first title of the series was Age of Empires, released in 1997. Since then, seven titles and three spin-offs have been released. The titles are historical real-time strategy games, and their gameplay revolves around two main game modes: Single player and campaign. They competed with another popular strategy series, Civilization, and are set amidst historical events.

Age of Empires focused on events in Europe, Africa and Asia, spanning from the Stone Age to the Iron Age; the expansion game explored the formation and expansion of the Roman Empire. The sequel, Age of Empires II: The Age of Kings, was set in the Middle Ages, while its expansion focused partially on the Spanish conquest of Mexico. The subsequent three games of Age of Empires III explored the early modern period, when Europe was colonizing the Americas and several Asian nations were on the decline. The newest installment, Age of Empires Online, takes a different approach as a free-to-play online game utilizing Games for Windows Live. A spin-off game, Age of Mythology, was set in the same period as the original Age of Empires, but focused on mythological elements of Greek, Egyptian, and Norse mythology.

Age of Empires II

Age of Empires II: The Age of Kings is a real-time strategy (RTS) video game developed by Ensemble Studios and published by Microsoft. Released in 1999 for the Microsoft Windows and Macintosh operating systems, it was the second game in the Age of Empires series. An expansion, The Conquerors, was released in 2000. A PlayStation 2 version was released by Konami in 2001, and a Nintendo DS spinoff, Age of Empires: The Age of Kings was developed by Backbone Entertainment in 2006. A Dreamcast port, by Konami, was canceled.

The Age of Kings is set in the Middle Ages and contains thirteen playable civilizations. Players aim to gather resources, which they use to build towns, create armies, and defeat their enemies. There are five historically based campaigns, which constrict the player to specialized and story-backed conditions. There are three additional single-player game modes, and multiplayer is supported. Despite using the same game engine and similar code to its predecessor, development of The Age of Kings took a year longer than expected, forcing Ensemble Studios to release Age of Empires: The Rise of Rome in 1998 instead. The design team focused on resolving significant issues in Age of Empires, but noted on release that some problems remained.
