The Core
''The Core'' is a 2003 American science fiction disaster film directed by Jon Amiel and starring Aaron Eckhart, Hilary Swank, Delroy Lindo, Stanley Tucci, D. J. Qualls, Richard Jenkins, Tcheky Karyo, Bruce Greenwood, and Alfre Woodard. The film focuses on a team whose mission is to drill to the center of the Earth and set off a series of nuclear explosions in order to restart the rotation of the Earth's core. The film was released on March 28, 2003, by Paramount Pictures. It received mixed reviews from critics and grossed $74 million worldwide with a production budget of $85 million. Plot Several small, disparate incidents involving the Earth's magnetic field cause scientists led by geophysicist Dr. Josh Keyes and scientists Dr. Serge Leveque and Dr. Conrad Zimsky to conclude that the Earth's molten core has stopped rotating. Unless it can be restarted, the field will collapse within months, exposing the surface to devastating solar radiation. The U.S. government back a secre ...

Unobtainium
Unobtainium is a term used in fiction, engineering, and common situations for a material ideal for a particular application but impractically hard to get. Unobtainium originally referred to materials that do not exist at all, but can also be used to describe real materials that are unavailable due to extreme rarity or cost. Less commonly, it can mean a device with desirable engineering properties for an application that are exceedingly difficult or impossible to achieve. The properties of any particular example of unobtainium depend on the intended use. For example, a pulley made of unobtainium might be massless and frictionless. But for a nuclear rocket, unobtainium might have the needed qualities of lightness, strength at high temperatures, and resistance to radiation damage: A combination of all three qualities is impossible with today's materials. The concept of unobtainium is often applied hand-wavingly, flippantly, or humorously. The word "unobtainium" derives humorously ...

Science Fiction Film
Science fiction (or sci-fi) is a film genre that uses speculative, fictional science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, spacecraft, robots, cyborgs, interstellar travel, time travel, or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition. The genre has existed since the early years of silent cinema, when Georges Melies' '' A Trip to the Moon'' (1902) employed trick photography effects. The next major example (first in feature length in the genre) was the film ''Metropolis'' (1927). From the 1930s to the 1950s, the genre consisted mainly of low-budget B movies. After Stanley Kubrick's landmark '' 2001: A Space Odyssey'' (1968), the science fiction film genre was taken more seriously. In the late 1970s, big-budget science fiction films filled with special effects became popular with audie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marianas Trench
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about in length and in width. The maximum known depth is at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. If Mount Everest were hypothetically placed into the trench at this point, its peak would still be underwater by more than . At the bottom of the trench, the water column above exerts a pressure of , more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is . In 2009, the Mariana Trench was established as a US National Monument. Monothalamea have been found in the trench by Scripps Institution of Oceanography researchers at a record depth of below the sea surface. Data has also suggested that microbial life forms thrive within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hacker
A hacker is a person skilled in information technology who uses their technical knowledge to achieve a goal or overcome an obstacle, within a computerized system by non-standard means. Though the term ''hacker'' has become associated in popular culture with a '' security hacker''someone who utilizes their technical know-how of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them – hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques in order to collect evidence on criminals and other malicious actors. This could include using anonymity tools (such as a VPN, or the dark web) to mask their identities online, posing as criminals themselves. Likewise, covert world agencies can employ hacking techniques in the legal conduct of their work. On the other hand, hacking and cyber-attacks are used extra- and illegally by law enforcemen ...

Major
Major (commandant in certain jurisdictions) is a military rank of commissioned officer status, with corresponding ranks existing in many military forces throughout the world. When used unhyphenated and in conjunction with no other indicators, major is one rank above captain, and one rank below lieutenant colonel. It is considered the most junior of the field officer ranks. Background Majors are typically assigned as specialised executive or operations officers for battalion-sized units of 300 to 1,200 soldiers while in some nations, like Germany, majors are often in command of a company. When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including ''general-major'' or ''major general'', denoting a low-level general officer, and ''sergeant major'', denoting the most senior non-commissioned officer (NCO) of a military unit. The term ''major'' can also be used with a hyphen to denote the leader of a military band such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commander
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain. Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used. Commander as a naval and air force rank Commander is a rank used in navies but is very rarely used as a rank in armies. The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war of no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Federal Government Of The United States
The federal government of the United States (U.S. federal government or U.S. government) is the national government of the United States, a federal republic located primarily in North America, composed of 50 states, a city within a federal district (the city of Washington in the District of Columbia, where most of the federal government is based), five major self-governing territories and several island possessions. The federal government, sometimes simply referred to as Washington, is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the U.S. Constitution in the Congress, the president and the federal courts, respectively. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts inferior to the Supreme Court. Naming The full name of the republic is "United States of America". No other name appears in the Constitution, and this i ...

Solar Radiation
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), p. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuring surface, the height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophysics
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.

Earth's Magnetic Field
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic ...
