Economics is the social science that analyzes the production, distribution, and consumption of goods and services. The term economicscomes from the Ancient Greek οἰκονομία (oikonomia, "management of a household, administration") from οἶκος (oikos, "house") + νόμος(nomos, "custom" or "law"), hence "rules of the house(hold)".^[1] Political economy was the earlier name for the subject, but economists in the late 19th century suggested "economics" as a shorter term for "economic science" that also avoided a narrow political-interest connotation and as similar in form to "mathematics", "ethics", and so forth.

A focus of the subject is how economic agents behave or interact and how economies work. Consistent with this, a primary textbook distinction is between microeconomics and macroeconomics. Microeconomics examines the behavior of basic elements in the economy, including individual agents (such as households and firms or as buyers and sellers) and markets, and their interactions. Macroeconomicsanalyzes the entire economy and issues affecting it, including unemployment, inflation, economic growth, and monetary and fiscal policy.

Other broad distinctions include those between positive economics (describing "what is") and normative economics (advocating "what ought to be"); between economic theory and applied economics; between rational and behavioral economics; and between mainstream economics(more "orthodox" and dealing with the "rationality-individualism-equilibrium nexus") and heterodox economics (more "radical" and dealing with the "institutions-history-social structure nexus").

Economic analysis may be applied throughout society, as in business, finance, health care, and government, but also to such diverse subjects as crime, education, the family, law, politics, religion, social institutions, war, and science. At the turn of the 21st century, the expanding domain of economics in the social sciences has been described as economic imperialism. An increasing number of economists have called for increased emphasis on environmental sustainability; this area of research is known as Ecological economics.

A military is an organization authorized by its greater society to use lethal force, usually including use of weapons, in defending its country by combating actual or perceived threats. The military may have additional functions of use to its greater society, such as advancing a political agenda e.g. military junta, supporting or promoting economic expansion through imperialism, and as a form of internal social control. As an adjective the term "military" is also used to refer to any property or aspect of a military. Militaries often function as societies within societies, by having their own military communities.

The profession of soldiering as part of a military is older than recorded history itself. Some of the most enduring images of the classical antiquity portray the power and feats of its military leaders. The Battle of Kadesh in 1274 BC was one of the defining points of Pharaoh Ramesses II 's reign and is celebrated in bas-relief on his monuments. A thousand years later the first emperor of unified China, Qin Shi Huang, was so determined to impress the gods with his military might that he was buried with an army of terracotta soldiers. The Romans were dedicated to military matters, leaving to posterity many treatises and writings as well as a large number of lavishly carved triumphal arches and victory columns.

A gun is a weapon designed to discharge a projectile. 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 firearms were invented in China in the 12th century, and the technology gradually spread through the rest of Asia and into Europe. Modern guns are typically described by their bore diameter (75mm) or calibre (7.62mm), the type of action employed (muzzle, breech, lever, bolt, revolver, semi-automatic, or automatic) together with the usual means of deportment (hand-held or mechanical mounting). They may be further distinguished by reference to the type of barrel used (rifled) and the barrel length (19 inch), the design's primary intended target (anti-aircraft), or the commonly accepted name for a particular variation (Gatling gun).

is a financial institution and a financial intermediary that accepts deposits and channels those deposits into lending activities, either directly by loaning or indirectly through capital markets. A bank is the connection between customers that have capital deficits and customers with capital surpluses.

Due to their influence within a financial system and an economy, banks are generally highly regulated in most countries. Most banks operate under a system known as fractional reserve banking where they hold only a small reserve of the funds deposited and lend out the rest for profit. They are generally subject to minimum capital requirements which are based on an international set of capital standards, known as the Basel Accords.

The oldest bank still in existence is Monte dei Paschi di Siena, headquartered in Siena, Italy, which has been operating continuously since 1472. It is followed by Berenberg Bank of Hamburg (1590) and Sveriges Riksbank of Sweden (1668).

Banking in its modern sense evolved in rich cities of Renaissance Italy, such as Florence, Venice and Genoa. In the history of banking, a number of banking dynasties—among them notably Medici, Fugger, Welser ,Berenberg, Baring and Rothschild^[8]—have played a central role over many centuries.

A tank is a tracked, armoured fighting vehicle designed for front-line combat which combines operational mobility and tactical offensive and defensive capabilities. 

Firepower is normally provided by a large-calibre main gun in a rotating turret and secondary machine guns, while heavy armour and all-terrain mobility provide protection for the tank and its crew, allowing it to perform all primary tasks of the armoured troops on the battlefield.

Tanks in World War I were developed separately and simultaneously by Great Britain and France as a means to break the deadlock of trench warfare on the Western Front. Their first use in combat was by the British Army on September 15, 1916 at Flers-Courcelette, during the Battle of the Somme. 

The name "tank" was adopted by the British during the early stages of their development, as a security measure to conceal their purpose (see etymology). While the French and British built thousands of tanks between them, Germany developed and brought into service only a single design the A7V producing 20 vehicles due to lack of capacities or resources.

Tanks of the interwar period evolved into the designs of World War II. Important concepts of armoured warfare were developed; the Soviet Union launched the first mass tank/air attack at Khalkhin Gol (Nomonhan) in August 1939, which later resulted in the T-34, a predecessor of the main battle tank; this was quickly followed up by Germany on a larger scale when they introduced blitzkrieg ('lightning war') less than two weeks later; a technique which made use of massed concentrations of tanks supported by artillery and air power to break through the enemy front and cause a complete collapse in enemy resistance and morale.

Tanks in the Cold War advanced to counter greater battlefield threats. Tanks became larger and their armour became thicker and much more effective. Advances in manufacturing late in the war allowed the mass production of composite armor. Aspects of gun technology changed significantly as well, with advances in shell design.

During the 20th century, main battle tanks were considered a key component of modern armies. In the 21st century, with the increasing role of asymetrical warfare and the end of the Cold War, that also contributed to the increase of cost-effective Russian anti-tank weapons worldwide, the importance of tanks has waned. Modern tanks seldom operate alone, as they are organized into armoured units which involve the support of infantry, who may accompany the tanks in infantry fighting vehicles. They are also usually supported byreconnaissance or ground-attack aircraft.

The Gundam Series  is a metaseries of anime created by Sunrise studios that features giant robots (or "mecha") called "Mobile Suits" (MS); usually the protagonist's MS will carry the name Gundam.

The metaseries started on April 7, 1979, as a serial TV show called Mobile Suit Gundam. That first TV series has since spawned a franchise that has come to include works released in numerous media. Titles have appeared in the form of multiple television series andOVAs, movies, manga, novels and video games, among other modes. The story from the original 1979 series has been considerably extended with sequels, prequels, side stories and alternate timelines. As a result, the title Gundam has become a collective term for the seven distinct but related timelines that can be pieced together from the stories that appear in the Gundam franchise. Generally speaking, the timelines do not intersect, but they do contain a few common elements such as the titular war machines called Gundam. However, all Gundam timelines and worlds, long after their own anime series, do eventually intersect and combine in the series Turn A Gundam.

The original timeline for the Gundam series was the Universal Century (UC) series, which included Mobile Suit Gundam (1979) andMobile Suit Zeta Gundam (1985). Since the 1990s, alternative timelines have been produced and developed, including the Future Century, After Colony, After War, Correct Century, Cosmic Era, Anno Domini and Advanced Generation timelines.

As of January 21, 2008, the Gundam franchise is a 50 billion yen trademark. A year 2000 press release stated that retail sales of Gundam items had totaled $5 billion. In the 2008 ranking of average sales figures for anime copies sold in Japan (1970-2008 total sales figures averaged by episode), Gundam series were in four of the top five places: Mobile Suit Gundam ranked second, with Mobile Suit Gundam SEED Destiny third, Mobile Suit Gundam SEED fourth, and Mobile Suit Zeta Gundam fifth. Also, Mobile Suit Gundam Wing ranked 18th and Mobile Suit Gundam ZZ ranked 20th. Gunpla's (Gundam Plastic model) holds 90% of the Japan character plastic model market.

Academics in Japan have also viewed the series as inspiration, with the International Gundam Society being the first academic institution based on an animated TV series.
