LOL, an acronym for laughing out loud or laugh out loud, is a common element of Internet slang. It was used historically on Usenet but is now widespread in other forms of computer-mediated communication, and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms for more emphatic expressions of laughter such as LMAO ("laugh(ing) my ass off"), and ROTFL or ROFL ("roll(ing) on the floor laughing"). Other unrelated expansions include the now mostly historical "lots of luck" or "lots of love" used in letter...
The Lockheed CL-1200 Lancer was a late 1960s company-funded proposal for a new and improved Lockheed F-104 Starfighter. It was intended for the export market and was in direct competition with the Northrop F-5E Tiger II, Dassault Mirage F1, Northrop YF-17 and the McDonnell Douglas F-4 Phantom II. Lockheed hoped to capitalize on its F-104 production experience through commonality of parts and systems, and minimize expenses by reusing tooling, jigs and existing factory facilities. Lockheed was also experienced in consortium production and further hoped to continue this arrangement with the CL-1200...
Mecha is a science fiction genre that centers on robots or machines controlled by people. These machines vary greatly in size, shape, and appearance. Some are little more than cars with arms and legs, while others are giant humanoid constructs. Different subgenres exist, with varying connotations of realism. The concept of Super Robot and Real Robot are two such examples found in Japanese anime.

The word "mecha" (メカ, meka) is an abbreviation first used in Japanese of the word "mechanical". In Japanese, mecha encompasses all mechanical objects, including cars, guns, computers...
The M61 Vulcan is a hydraulically or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for fifty years.
The M61 was originally produced by General Electric, and after several mergers and acquisitions is currently produced by General Dynamics.

The McDonnell Douglas (now Boeing) F/A-18 Hornet is a twin-engine supersonic, all-weather carrier-capable multirole combat jet, designed as both a fighter and attack aircraft (F/A designation for Fighter/Attack). Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the latter's YF-17 in the 1970s for use by the United States Navy and Marine Corps. The Hornet is also used by the air forces of several other nations. The U.S. Navy's Flight Demonstration Squadron, the Blue Angels, has used the Hornet since 1986.
The F/A-18 has a top speed of Mach 1.8 (1,190 mph or 1,915 km/h at 40...
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole fighters undergoing testing and final development by the United States. The fifth generation combat aircraft is designed to perform ground attack, aerial reconnaissance, and air defense missions. The F-35 has three main models: the F-35A conventional takeoff and landing (CTOL) variant, the F-35B short take-off and vertical-landing (STOVL) variant, and the F-35C carrier-based Catapult Assisted Take-Off Barrier Arrested Recovery (CATOBAR) variant.
The F-35 is descended from the X-35, which...
Cattle—colloquially cows—are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos taurus. Cattle are raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as draft animals (oxen or bullocks) (pulling carts, plows and the like). Other products include leather and dung for manure or fuel. In some regions, such as parts of India, cattle have significant religious meaning. From as few as 80...

A wiki (/ˈwɪki/ WIK-ee) is an application, typically a web application, which allows collaborative modification, extension, or deletion of its content and structure. In a typical wiki, text is written using a simplified markup language (known as "wiki markup") or a rich-text editor. While a wiki is a type of content management system, it differs from a blog or most other such systems in that the content is created without any defined owner or leader, and wikis have little implicit structure, allowing structure to emerge according to the needs of the users.

A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the UK beer barrel and US beer barrel), oil barrels and so on. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common usage range from about 100 litres (22 imp gal; 26 US gal) to 200 litres (44 imp gal; 53 US gal). In many connections the term "drum" is used almost interchangeably with "barrel".
Since medieval times the term barrel as a unit of measure has had various meanings throughout Europe, ranging from about 100...

In mathematics, a square root of a number a is a number y such that y2 = a, in other words, a number y whose square (the result of multiplying the number by itself, or y × y) is a. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16.
Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by √a, where √ is called the radical sign or radix. For example, the principal square root of 9 is 3, denoted √9 = 3, because 32 = 3 × 3 = 9 and 3 is non-negative. The term whose root is being considered is known as the radicand...
