Destination Moon (film)
''Destination Moon'' (a.k.a. ''Operation Moon'') is a 1950 American Technicolor science fiction film, independently produced by George Pal and directed by Irving Pichel, that stars John Archer, Warner Anderson, Tom Powers, and Dick Wesson. The film was distributed in the United States and the United Kingdom by Eagle-Lion Classics. ''Destination Moon'' was the first major U.S. science fiction film to deal with the practical scientific and engineering challenges of space travel and to speculate on what a crewed expedition to the Moon would look like. Noted science fiction author Robert A. Heinlein contributed to the screenplay. The film's premise is that private industry will mobilize, finance, and manufacture the first spacecraft to the Moon, and that the U.S. government will be forced to purchase or lease the technology to remain the dominant power in space. Different industrialists cooperate to support the private venture. In the final scene, as the crew approaches the Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irving Pichel
Irving Pichel (June 24, 1891 – July 13, 1954) was an American actor and film director, who won acclaim both as an actor and director in his Hollywood career. Career Pichel was born to a Jewish family in Pittsburgh. He attended Pittsburgh Central High School with George S. Kaufman. The two collaborated on a play, ''The Failure''. Pichel graduated from Harvard University in 1914 and went immediately into the theater. Pichel's first work in musical theatre was as a technical director for the theater of the San Francisco Bohemian Club; he also helped with the annual summer pageant, held at the elite Bohemian Grove, in which up to 300 of its wealthy, influential members from finance and government participate. With this expertise, he was also hired by Wallace Rice as the main narrator in Rice's ambitious pageant play, ''Primavera, the Masque of Santa Barbara'' in 1920. He founded the Berkeley Playhouse in 1923 and served as its director until 1926. Actor Pichel moved to Los ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eagle-Lion Classics
Eagle-Lion Films was a British-American film production company owned by J. Arthur Rank intended to distribute British productions in the United States. In 1947, it acquired Robert R. Young's PRC Pictures, a small American production company, to produce low-budget features to accompany its British releases. The studio, which was located at 7324 Santa Monica Boulevard (one block away from the Samuel Goldwyn Studios), became a producer of B-movies. Eagle-Lion was also a film distribution company under the name of Eagle-Lion Distributors Limited in the United Kingdom and Eagle-Lion Films Inc. in the United States. In 1954, the film lot was purchased by the Ziv Company for production of its syndicated television programs. It has long since been demolished. History The company was founded in September 1946. From 1946 to 1949, Eagle-Lion was under the control of Arthur B. Krim who, in addition to releasing films by Rank and reissues of David O. Selznick, films produced his own B-mo ...

Atlas (mythology)
In Greek mythology, Atlas (; grc-gre, Ἄτλας, ''Átlas'') is a Titan condemned to hold up the heavens or sky for eternity after the Titanomachy. Atlas also plays a role in the myths of two of the greatest Greek heroes: Heracles (Hercules in Roman mythology) and Perseus. According to the ancient Greek poet Hesiod, Atlas stood at the ends of the earth in extreme west. Later, he became commonly identified with the Atlas Mountains in northwest Africa and was said to be the first King of Mauretania. Atlas was said to have been skilled in philosophy, mathematics, and astronomy. In antiquity, he was credited with inventing the first celestial sphere. In some texts, he is even credited with the invention of astronomy itself. Atlas was the son of the Titan Iapetus and the Oceanid Asia or Clymene. He was a brother of Epimetheus and Prometheus. He had many children, mostly daughters, the Hesperides, the Hyades, the Pleiades, and the nymph Calypso who lived on the isla ...

Forced Perspective
Forced perspective is a technique that employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It manipulates human visual perception through the use of scaled objects and the correlation between them and the vantage point of the spectator or camera. It has uses in photography, filmmaking and architecture. In filmmaking An example of forced perspective is a scene in an action movie in which dinosaurs are threatening the heroes. By placing a miniature model of a dinosaur close to the camera, the director may make the dinosaur look monstrously tall to the viewer, even though it is just closer to the camera. Forced perspective had been a feature of German silent films and ''Citizen Kane'' revived the practice. Movies, especially B-movies in the 1950s and 1960s, were produced on limited budgets and often featured forced perspective shots. Forced perspective can be made more believable when environmental conditions obscure the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Fall
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it. An object in the technical sense of the term "free fall" may not necessarily be falling down in the usual sense of the term. An object moving upwards might not normally be considered to be falling, but if it is subject to only the force of gravity, it is said to be in free fall. The Moon is thus in free fall around the Earth, though its orbital speed keeps it in very far orbit from the Earth's surface. In a roughly uniform gravitational field gravity acts on each part of a body approximately equally. When there are no other forces, such as the normal force exerted between a body (e.g. an astronaut in orbit) and its surrounding objects, it will result in the sensation of weightlessness, a condition that also occurs when the gravi ...

Appendicitis
Appendicitis is inflammation of the appendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. However, approximately 40% of people do not have these typical symptoms. Severe complications of a ruptured appendix include widespread, painful inflammation of the inner lining of the abdominal wall and sepsis. Appendicitis is caused by a blockage of the hollow portion of the appendix. This is most commonly due to a calcified "stone" made of feces. Inflamed lymphoid tissue from a viral infection, parasites, gallstone, or tumors may also cause the blockage. This blockage leads to increased pressures in the appendix, decreased blood flow to the tissues of the appendix, and bacterial growth inside the appendix causing inflammation. The combination of inflammation, reduced blood flow to the appendix and distention of the appendix causes tissue injury and tissue death. If this process is left untreated, the appendix may burst, releasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

Radiation Safety
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive contamination. Ionizing radiation is widely used in industry and medicine, and can present a significant health hazard by causing microscopic damage to living tissue. There are two main categories of ionizing radiation health effects. At high exposures, it can cause "tissue" effects, also called "deterministic" effects due to the certainty of them happening, conventionally indicated by the unit gray and resulting in acute radiation syndrome. For low level exposures there can be statistically elevated risks of radiation-induced cancer, called "stochastic effects" due to the uncertainty of them happening, ...

Nuclear Propulsion
Nuclear propulsion includes a wide variety of propulsion methods that use some form of nuclear reaction as their primary power source. The idea of using nuclear material for propulsion dates back to the beginning of the 20th century. In 1903 it was hypothesized that radioactive material, radium, might be a suitable fuel for engines to propel cars, planes, and boats. H. G. Wells picked up this idea in his 1914 fiction work '' The World Set Free''. Surface ships, submarines, and torpedoes Nuclear-powered vessels are mainly military submarines, and aircraft carriers. Russia is the only country that currently has nuclear-powered civilian surface ships, mainly icebreakers. The US Navy currently (as of 2022) has 11 aircraft carriers and 70 submarines in service, that are all powered by nuclear reactors.

Single-stage-to-orbit
A single-stage-to-orbit (SSTO) vehicle reaches orbit from the surface of a body using only propellants and fluids and without expending tanks, engines, or other major hardware. The term usually, but not exclusively, refers to reusable vehicles. To date, no Earth-launched SSTO launch vehicles have ever been flown; orbital launches from Earth have been performed by either fully or partially expendable multi-stage rockets. The main projected advantage of the SSTO concept is elimination of the hardware replacement inherent in expendable launch systems. However, the non-recurring costs associated with design, development, research and engineering (DDR&E) of reusable SSTO systems are much higher than expendable systems due to the substantial technical challenges of SSTO, assuming that those technical issues can in fact be solved. SSTO vehicles may also require a significantly higher degree of regular maintenance. It is considered to be marginally possible to launch a single-stage- ...

Magnate
The magnate term, from the late Latin ''magnas'', a great man, itself from Latin ''magnus'', "great", means a man from the higher nobility, a man who belongs to the high office-holders, or a man in a high social position, by birth, wealth or other qualities in Western Christian countries since the medieval period. It also includes the members of the higher clergy, such as bishops, archbishops and cardinals. In reference to the medieval, the term is often used to distinguish higher territorial landowners and warlords, such as counts, earls, dukes, and territorial-princes from the baronage, and in Poland for the richest '' szlachta''. England In England, the magnate class went through a change in the later Middle Ages. It had previously consisted of all tenants-in-chief of the crown, a group of more than a hundred families. The emergence of Parliament led to the establishment of a parliamentary peerage that received personal summons, rarely more than sixty families. A simil ...
