Replicator (Star Trek)
In ''Star Trek'' a replicator is a machine that can create (and recycle) things. Replicators were originally seen to simply synthesize meals on demand, but in later series much larger non-food items appear. The technical aspects of replicated versus "real" things is sometimes a plot element. Origins and limitations Although previous sci-fi writers had speculated about the development of "replicating" or "duplicating" technology, the term "replicator" was not itself used until '' Star Trek: The Next Generation''. In simple terms, it was described as a 24th century advancement from the 23rd century "food synthesizer" seen in ''Star Trek: The Original Series''. In Star Trek: The Original Series, food was created in various colored cubes. In the animated series (1974), various types of realistic-looking food could be requested, as in the episode entitled "The Practical Joker." The mechanics of these devices were never clearly explained on that show. The subsequent prequel series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star Trek
''Star Trek'' is an American science fiction media franchise created by Gene Roddenberry, which began with the eponymous 1960s television series and quickly became a worldwide pop-culture phenomenon. The franchise has expanded into various films, television series, video games, novels, and comic books. With an estimated $10.6 billion in revenue, it is one of the most recognizable and highest-grossing media franchises of all time. The franchise began with ''Star Trek: The Original Series'', which debuted in the US on September 8, 1966 and aired for three seasons on NBC. It was first broadcast on September 6, 1966 on Canada's CTV network. It followed the voyages of the crew of the starship USS ''Enterprise'', a space exploration vessel built by the United Federation of Planets in the 23rd century, on a mission "to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before". In creating ''Star Trek'', Roddenberry w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulation
A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of Conceptual model, models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the computer simulation, simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning, as in economics. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed bu ...

Clothing
Clothing (also known as clothes, apparel, and attire) are items worn on the body. Typically, clothing is made of fabrics or textiles, but over time it has included garments made from animal skin and other thin sheets of materials and natural products found in the environment, put together. The wearing of clothing is mostly restricted to human beings and is a feature of all human societies. The amount and type of clothing worn depends on gender, body type, social factors, and geographic considerations. Garments cover the body, footwear covers the feet, gloves cover the hands, while hats and headgear cover the head. Eyewear and jewelry are not generally considered items of clothing, but play an important role in fashion and clothing as costume. Clothing serves many purposes: it can serve as protection from the elements, rough surfaces, sharp stones, rash-causing plants, insect bites, by providing a barrier between the skin and the environment. Clothing can insulate against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. ( Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter. If the executable is requested for execution, then the operating system loads it into memory and starts a process. The central processing unit will soon switch to this process so it can fetch, decode, and then execute each machine instruction. If the source code is requested for execution, ...

Holodeck
The Holodeck is a fictional device from the television franchise ''Star Trek'' which uses "holograms" (projected light and electromagnetic energy which create the illusion of solid objects) to create a realistic 3D simulation of a real or imaginary setting, in which participants can freely interact with the environment as well as objects and characters, and sometimes a predefined narrative. In several series, holodecks are an amenity available to the crew of starships. In the series '' Star Trek: Deep Space Nine'', a similar device is referred to as a holosuite, operated by the owner of the space station's bar, Quark, who rents them out to customers. From a storytelling point of view, the holodeck permits the introduction of a wide variety of locations and characters, such as events and persons in the Earth's past, or imaginary places or beings, that would otherwise require the use of plot mechanisms such as time-travel or dream sequences. Writers often use it as a way to pose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...

Crew
A crew is a body or a class of people who work at a common activity, generally in a structured or hierarchical organization. A location in which a crew works is called a crewyard or a workyard. The word has nautical resonances: the tasks involved in operating a ship, particularly a sailing ship, providing numerous specialities within a ship's crew, often organised with a chain of command. Traditional nautical usage strongly distinguishes officers from crew, though the two groups combined form the ship's company. Members of a crew are often referred to by the title ''crewman'' or ''crew-member''. ''Crew'' also refers to the sport of rowing, where teams row competitively in racing shells.

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Starbase
The concepts of space stations and space habitats feature in science fiction. The difference between the two is that habitats are larger and more complex structures intended as permanent homes for substantial populations (though generation ships also fit this description, they are usually not considered space habitats as they are heading for a destination), but the line between the two is fuzzy with significant overlap and the term space station is sometimes used for both concepts. The first such artificial satellite in fiction was Edward Everett Hale's " The Brick Moon" in 1869, a sphere of bricks 61 meters across accidentally launched into orbit around the Earth with people still onboard. Space stations Space stations started appearing frequently in science fiction works following the release of the 1949 popular science book '' The Conquest of Space'' by Willy Ley, which deals with the subject. They serve several disparate functions in different works. Among these are indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmosphere Of Earth
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

Deep Space Nine
''Star Trek: Deep Space Nine'' (abbreviated as ''DS9'') is an American science fiction television series created by Rick Berman and Michael Piller. The fourth series in the ''Star Trek'' media franchise, it originally aired in syndication from January 3, 1993, to June 2, 1999, spanning 176 episodes over seven seasons. Set in the 24th century, when Earth is part of a United Federation of Planets, its narrative is centered on the eponymous space station Deep Space Nine, located adjacent to a wormhole connecting Federation territory to the Gamma Quadrant on the far side of the Milky Way galaxy. Following the success of '' Star Trek: The Next Generation'', Paramount Pictures commissioned a new series set in the ''Star Trek'' fictional universe. In creating ''Deep Space Nine'', Berman and Piller drew upon plot elements introduced in ''The Next Generation'', namely the conflict between two alien species, the Cardassians and the Bajorans.
