Black Mesa Research Facility
The Black Mesa Research Facility (also simply called Black Mesa) is a fictional underground laboratory complex that serves as the primary setting for the video game ''Half-Life'' and its expansions, as well as its remake, '' Black Mesa''. It also features in the wider ''Half-Life'' universe, including the ''Portal'' series. Located in the New Mexico desert in a decommissioned Cold War missile site, it is the former employer of ''Half-Life'''s protagonist, Gordon Freeman, a theoretical physicist, and a competitor of Aperture Science. While the facility ostensibly conducts military-industrial research, its secret experiments into teleportation have caused it to make contact with the alien world of Xen, and its scientists covertly study its life-forms and materials. An "anti-mass spectrometer" experiment conducted on Xen matter causes a Resonance Cascade disaster that allows aliens to invade Earth, and is the catalyst for the events of the series. ''Half-Life'' was critically ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half-Life (video Game)
''Half-Life'' is a 1998 first-person shooter (FPS) game developed by Valve and published by Sierra Studios for Windows. It was Valve's debut product and the first game in the ''Half-Life'' series. Players assume the role of Gordon Freeman, a scientist who must escape the Black Mesa Research Facility after it is invaded by aliens. The gameplay consists of combat, exploration, and puzzle-solving. Unlike other games of the time, the player has almost uninterrupted control of the player character, and the story is told mostly in scripted sequences rather than cutscenes. Valve co-founder Gabe Newell said that the team was disappointed with the lack of innovation in the FPS genre, and aimed to create an immersive world rather than a "shooting gallery". Valve developed using GoldSrc, a heavily modified version of the ''Quake'' engine, licensed from id Software. The science fiction novelist Marc Laidlaw was hired to shape the story and assist with design. ''Half-Life'' received accl ...

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concerned wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monorail
A monorail (from "mono", meaning "one", and "rail") is a railway in which the track consists of a single rail or a beam. Colloquially, the term "monorail" is often used to describe any form of elevated rail or people mover. More accurately, the term refers to the style of track.The term "track" is used here for simplicity. Technically the monorail sits on or is suspended from a guideway containing a singular structure. There is an additional generally accepted rule that the support for the car be narrower than the car. Etymology The term possibly comes from 1897, from German engineer Eugen Langen, who called an elevated railway system with wagons suspended the '' Eugen Langen One-railed Suspension Tramway'' (Einschieniges Hängebahnsystem Eugen Langen). Differentiation from other transport systems Monorails have found applications in airport transfer and medium capacity metros. To differentiate monorails from other transport modes, the Monorail Society defines a monorail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First-person Shooter
First-person shooter (FPS) is a sub-genre of shooter video games centered on gun and other weapon-based combat in a first-person perspective, with the player experiencing the action through the eyes of the protagonist and controlling the player character in a three-dimensional space. The genre shares common traits with other shooter games, and in turn falls under the action game genre. Since the genre's inception, advanced 3D and pseudo-3D graphics have challenged hardware development, and multiplayer gaming has been integral. The first-person shooter genre has been traced back to ''Wolfenstein 3D'' (1992), which has been credited with creating the genre's basic archetype upon which subsequent titles were based. One such title, and the progenitor of the genre's wider mainstream acceptance and popularity, was ''Doom'' (1993), often considered the most influential game in this genre; for some years, the term ''Doom'' clone was used to designate this genre due to ''Doom''s i ...

Non-player Character
A non-player character (NPC), or non-playable character, is any character in a game that is not controlled by a player. The term originated in traditional tabletop role-playing games where it applies to characters controlled by the gamemaster or referee rather than by another player. In video games, this usually means a character controlled by the computer (instead of a player) that has a predetermined set of behaviors that potentially will impact gameplay, but will not necessarily be the product of true artificial intelligence. Role-playing games In a traditional tabletop role-playing game such as ''Dungeons & Dragons'', an NPC is a character portrayed by the gamemaster (GM). While the player characters (PCs) form the narrative's protagonists, non-player characters can be thought of as the "supporting cast" or "extras" of a roleplaying narrative. Non-player characters populate the fictional world of the game, and can fill any role not occupied by a player character. Non-player ...

Cutscene
A cutscene or event scene (sometimes in-game cinematic or in-game movie) is a sequence in a video game that is not interactive, interrupting the gameplay. Such scenes are used to show conversations between characters, set the mood, reward the player, introduce newer models and gameplay elements, show the effects of a player's actions, create emotional connections, improve pacing or foreshadow future events. Cutscenes often feature "on the fly" rendering, using the gameplay graphics to create scripted events. Cutscenes can also be pre-rendered computer graphics streamed from a video file. Pre-made videos used in video games (either during cutscenes or during the gameplay itself) are referred to as " full motion videos" or "FMVs". Cutscenes can also appear in other forms, such as a series of images or as plain text and audio. History ''The Sumerian Game'' (1966), an early mainframe game designed by Mabel Addis, introduced its Sumerian setting with a slideshow synchronized to ...

Narrative
A narrative, story, or tale is any account of a series of related events or experiences, whether nonfictional (memoir, biography, news report, documentary, travel literature, travelogue, etc.) or fictional (fairy tale, fable, legend, thriller (genre), thriller, novel, etc.). Narratives can be presented through a sequence of written or spoken words, through still or moving images, or through any combination of these. The word derives from the Latin verb ''narrare'' (to tell), which is derived from the adjective ''gnarus'' (knowing or skilled). Narration (i.e., the process of presenting a narrative) is a rhetorical modes, rhetorical mode of discourse, broadly defined (and paralleling argumentation, description, and exposition (narrative), exposition), is one of four rhetorical modes of discourse. More narrowly defined, it is the fiction-writing mode in which a narrator communicates directly to an audience. The school of literary criticism known as Russian formalism has applied metho ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Spectrometry
Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a ''mass spectrum'', a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds. In a typical MS procedure, a sample, which may be solid, liquid, or gaseous, is ionized, for example by bombarding it with a beam of electrons. This may cause some of the sample's molecules to break up into positively charged fragments or simply become positively charged without fragmenting. These ions (fragments) are then separated accordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extraterrestrial Life
Extraterrestrial life, colloquially referred to as alien life, is life that may occur outside Earth and which did not originate on Earth. No extraterrestrial life has yet been conclusively detected, although efforts are underway. Such life might range from simple forms like prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humankind. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology. Speculation about the possibility of inhabited "worlds" outside the planet Earth dates back to antiquity. Multiple early Christian writers discussed the idea of a "plurality of worlds" as proposed by earlier thinkers such as Democritus; Augustine references Epicurus's idea of innumerable worlds "throughout the boundless immensity of space" (originally expressed in his Letter to Herodotus) in ''The City of God''. In his first century p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xen (Half-Life)
The Half-Life (series), ''Half-Life'' video game series features many locations set in a dystopian future stemming from the events of the first game, Half-Life (video game), ''Half-Life''. These locations are used and referred to throughout the series. The locations, for the most part, are designed and modeled from real-world equivalent locations in Eastern Europe, but also include science fiction settings including the Black Mesa Research Facility, a labyrinthine subterranean research complex, and Xen, an alien dimension. ''Half-Life'' and expansions Black Mesa Research Facility The Black Mesa Research Facility (shortened to B.M.R.F) is the primary setting for ''Half-Life (video game), Half-Life'' and its three expansions: ''Half-Life: Opposing Force, Opposing Force'', ''Half-Life: Blue Shift, Blue Shift'', and ''Half-Life: Decay, Decay''. The base is a decommissioned Intercontinental ballistic missile, ICBM Missile launch facility, launch complex at an undisclosed New Mexic ...

Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like starsFor the purpose of this 1 in 5 statistic, "Sun-like" means G-type star.
