A Fall Of Moondust
''A Fall of Moondust'' is a hard science fiction novel by British writer Arthur C. Clarke, first published in 1961. It was nominated for a Hugo Award for Best Novel, and was the first science fiction novel selected to become a ''Reader's Digest'' Condensed Book. Plot By the 21st century, the Moon has been colonized, and although still very much a research establishment, it is visited by tourists who can afford the trip. One of its attractions is a cruise across one of the lunar seas, named the ''Sea of Thirst'', (located within the Sinus Roris) filled with an extremely fine dust, a fine powder far drier than the contents of a terrestrial desert and which almost flows like water, instead of the common regolith which covers most of the lunar surface. A specially designed "boat" named the ''Selene'' skims over the surface of the dust in the same manner as a jetski. But on one cruise, a moonquake causes a cavern to collapse, upsetting the equilibrium. As the dust-cruiser Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur C
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Space Tourism
Space tourism is human space travel for recreational purposes. There are several different types of space tourism, including orbital, suborbital and lunar space tourism. During the period from 2001 to 2009, seven space tourists made eight space flights aboard a Russian Soyuz spacecraft to the International Space Station, brokered by Space Adventures in conjunction with Roscosmos and RSC Energia. The publicized price was in the range of US$20–25 million per trip. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit. By 2007, space tourism was thought to be one of the earliest markets that would emerge for commercial spaceflight. Russia halted orbital space tourism in 2010 due to the increase in the International Space Station crew size, using the seats for expedition crews that would previously have been sold to paying spaceflight participants. Orbital tourist flights were set to resume in 2015 but the planned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Galaxy Science Fiction
''Galaxy Science Fiction'' was an American digest-size science fiction magazine, published in Boston from 1950 to 1980. It was founded by a French-Italian company, World Editions, which was looking to break into the American market. World Editions hired as editor H. L. Gold, who rapidly made ''Galaxy'' the leading science fiction magazine of its time, focusing on stories about social issues rather than technology. Gold published many notable stories during his tenure, including Ray Bradbury's "The Fireman", later expanded as ''Fahrenheit 451''; Robert A. Heinlein's ''The Puppet Masters''; and Alfred Bester's ''The Demolished Man''. In 1952, the magazine was acquired by Robert Guinn, its printer. By the late 1950s, Frederik Pohl was helping Gold with most aspects of the magazine's production. When Gold's health worsened, Pohl took over as editor, starting officially at the end of 1961, though he had been doing the majority of the production work for some time. Under Pohl ''Gala ...

Imperial Earth
''Imperial Earth'' is a science fiction novel by British writer Arthur C. Clarke, published in 1975 by Gollancz Books. The plot follows the protagonist, Duncan Makenzie, on a trip to Earth from his home on Titan, in large part as a diplomatic visit to the U.S. for its quincentennial in 2276, but also to have a clone of himself produced. The book was published in time for the U.S. bicentennial in 1976. Plot summary Duncan Makenzie is the latest generation of the 'first family' of Titan, a colonised moon of Saturn. Originally settled by his grandfather Malcolm Makenzie in the early 23rd century, Titan's economy has flourished based on the harvest and sale of hydrogen mined from the atmosphere, which is used to fuel the fusion engines of interplanetary spacecraft. As the plot opens in 2276, a number of factors are combining to make a diplomatic visit to the 'mother world' of Earth a necessity. Firstly, the forthcoming 500th anniversary of US Independence, which is bringin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaped Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significant ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pref ...
