Monomolecular Wire
Monomolecular wire is a type of wire consisting of a single strand of strongly bonded atoms or molecules, like carbon nanotubes. In science Organic molecular wires have been proposed for use in optoelectronics. In fiction Among the earliest descriptions of a super-strong filament are the film ''The Man in the White Suit'', in which a scientist develops a monofilament cloth fibre that will never wear out, and Theodore Sturgeon's "The Incubi of Parallel X" (Planet Stories, Sep 1951), where a "molecularly condensed fibre" is used as a zipline. An early example of a material similar to monomolecular wire deliberately used as a weapon and cutting tool is "borazon-tungsten filament" in G. Randall Garrett's "Thin Edge". (Analog, Dec 1963) The main character uses a strand from an asteroid towing-cable to cut jail bars and to booby-trap the door of his room. Many later writers, including John Brunner, Frank Herbert, William Gibson and George R. R. Martin, have also used monomolecular ...

Carbon Nanotube
A scanning tunneling microscopy image of a single-walled carbon nanotube Rotating single-walled zigzag carbon nanotube A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. ''Single-wall carbon nanotubes'' (''SWCNTs'') are one of the allotropes of carbon, intermediate between fullerene cages and flat graphene, with diameters in the range of a nanometre. Although not made this way, single-wall carbon nanotubes can be idealized as cutouts from a two-dimensional Hexagonal tiling, hexagonal lattice of carbon atoms rolled up along one of the Bravais lattice vectors of the hexagonal lattice to form a hollow cylinder. In this construction, periodic boundary conditions are imposed over the length of this roll-up vector to yield a helical lattice of seamlessly bonded carbon atoms on the cylinder surface. ''Multi-wall carbon nanotubes'' (''MWCNTs'') consisting of nested single-wall carbon nanotubes weakly bound together by van der Waals in ...

The Fountains Of Paradise
''The Fountains of Paradise'' is a 1979 science fiction novel by British writer Arthur C. Clarke. Set in the 22nd century, it describes the construction of a space elevator. This "orbital tower" is a giant structure rising from the ground and linking with a satellite in geostationary orbit at the height of approximately 36,000 kilometers (approx. 22,300 miles). Such a structure would be used to raise payloads to orbit without the expense of using rockets. The novel won both the Hugo and Nebula Awards for Best Novel. Plot Summary The novel focuses primarily on a project known as the Orbital Tower proposed by the main character, Vannevar Morgan. The tower is to stretch from the Earth's equator to a satellite that is in geostationary orbit. Such a structure would greatly reduce the cost of sending people and supplies into space. The main story is framed by two other stories. The first one tells of King Kalidasa, living thousands of years before Morgan is born, who is constru ...

Emerging Technologies
Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized. These technologies are generally new but also include older technologies finding new applications. Emerging technologies are often perceived as capable of changing the status quo. Emerging technologies are characterized by radical novelty (in application even if not in origins), relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the socio-economic domain(s) which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes. Its most prominent impact, however, lies in the future and so in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allotropes Of Carbon
Carbon is capable of forming many allotropes (structurally different forms of the same element) due to its valency. Well-known forms of carbon include diamond and graphite. In recent decades, many more allotropes have been discovered and researched, including ball shapes such as buckminsterfullerene and sheets such as graphene. Larger-scale structures of carbon include carbon nano tube, nanotubes, nanobuds and nanoribbons. Other unusual forms of carbon exist at very high temperatures or extreme pressures. Around 500 hypothetical 3‑periodic allotropes of carbon are known at the present time, according to the Samara Carbon Allotrope Database (SACADA). Diamond Diamond is a well-known allotrope of carbon. The hardness, extremely high refractive index, and high dispersion of light make diamond useful for industrial applications and for jewelry. Diamond is the hardest known natural mineral. This makes it an excellent abrasive and makes it hold polish and luster extre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire
Overhead power cabling. The conductor consists of seven strands of steel (centre, high tensile strength), surrounded by four outer layers of aluminium (high conductivity). Sample diameter 40 mm A wire is a flexible strand of metal. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. Wires are used to bear mechanical loads, often in the form of wire rope. In electricity and telecommunications signals, a "wire" can refer to an electrical cable, which can contain a "solid core" of a single wire or separate strands in stranded or braided forms. Usually cylindrical in geometry, wire can also be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-wound coil springs, such as the Slinky toy, are made of special flatten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fictional Technology
Technology in science fiction is a crucial aspect of the genre. As science fiction emerged during the era of Industrial Revolution, the increased presence of machines in everyday life and their role in shaping of the society was a major influence on the genre. It appeared as a major element of the Proto SF, represented by machines and gadgets in works of Jules Verne, George Griffith, H. G. Wells, Edward Bellamy and others. Technology has been portrayed both in positive or negative ways; in some works it is a solution to the world problems, in others, a means of its destruction. Such things as robots and space travel became commonplace in the fiction of the 19th century. Concepts and illustrations of technology in science fiction have been a significant influence in the formation of popular culture images of future technology. Science fiction has often affected innovation and new technology – for example many rocketry pioneers were inspired by science fiction. See also ...

Robert A
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of ''Hrōþ, Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use Robert (surname), as a surname. Another commonly used form of the name is Rupert (name), Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta (given name), Roberta. The Italian, Portuguese, and Spanish form is Roberto (given name), Roberto. Robert is also a common name in many Germanic languages, including English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Web Between The Worlds
''The Web Between the Worlds'' is the second science fiction novel by Charles Sheffield. It was first published as a trade paperback by Ace Books in 1979, by the first UK edition in hardcover by Sidgwick & Jackson Ltd the following year. Further editions were published by Arrow Books, Ace Books, Del Rey/Ballantyne and others; in 2001 Baen Books issued a revised edition. The novel has also been translated into German and French. This novel and the simultaneously published novel ''The Fountains of Paradise'', by Arthur C. Clarke, are the first popularization of the space elevator. Plot The novel tells the story of Rob Merlin, the best engineer who has ever lived. His machine, the "Spider," extrudes graphite cables of incredible strength. Darius Regulo has a monopoly on space mining, and doesn't like rockets. Half of their fuel is used to lift the ''other'' half, a waste of energy. Regulo wants to build a space elevator, and hires Merlin to do it. Merlin will need to modify hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Sheffield
Charles Sheffield (25 June 1935 – 2 November 2002), an English-born mathematician, physicist and science-fiction writer, served as a President of the Science Fiction and Fantasy Writers of America and of the American Astronautical Society. His novel '' The Web Between the Worlds'', featuring the construction of a space elevator, was published almost simultaneously with Arthur C. Clarke's novel on the subject, ''The Fountains of Paradise'' - a coincidence that amused them both. Excerpts from both Sheffield's '' The Web Between the Worlds'' and Clarke's ''The Fountains of Paradise'' have appeared recently in a space-elevator anthology, '' Towering Yarns''. Sheffield served as Chief Scientist of Earth Satellite Corporation, a company that processed remote-sensing satellite data. The association gave rise to many technical papers and two popular non-fiction books, ''Earthwatch'' (1981) and ''Man on Earth'' (1983), both collections of false-colour and enhanced images of E ...
