Hyperion (Simmons Novel)
''Hyperion'' is a 1989 science fiction novel by American author Dan Simmons. The first book of his ''Hyperion Cantos'', it won the Hugo Award for best novel. The plot of the novel features multiple time-lines and characters. It follows a similar structure to ''The Canterbury Tales'' by Geoffrey Chaucer. The next book in the series was '' The Fall of Hyperion'', published in 1990. Plot summary Premise In the 29th century, the Hegemony of Man comprises hundreds of planets connected by farcaster portals. The Hegemony maintains an uneasy alliance with the TechnoCore, a civilization of AIs. Modified humans known as Ousters live in space stations between stars and are engaged in conflict with the Hegemony. Numerous "Outback" planets have no farcasters and cannot be accessed without incurring significant time dilation. One of these planets is Hyperion, home to structures known as the Time Tombs, which are moving backwards in time and guarded by a legendary creature known as the S ...

WikiProject Novels
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Time Dilation
In physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them ( special relativistic "kinetic" time dilation) or to a difference in gravitational potential between their locations ( general relativistic gravitational time dilation). When unspecified, "time dilation" usually refers to the effect due to velocity. After compensating for varying signal delays due to the changing distance between an observer and a moving clock (i.e. Doppler effect), the observer will measure the moving clock as ticking slower than a clock that is at rest in the observer's own reference frame. In addition, a clock that is close to a massive body (and which therefore is at lower gravitational potential) will record less elapsed time than a clock situated further from the said massive body (and which is at a higher gravitational potential). These predictions of the theory of relativity have been repeatedl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stargazing
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binding Of Isaac
The Binding of Isaac ( he, , ), or simply "The Binding" (, ), is a story from Genesis 22 of the Hebrew Bible. In the biblical narrative, God tells Abraham to sacrifice his son, Isaac, on Moriah. As Abraham begins to comply, having bound Isaac to an altar, he is stopped by the Angel of the Lord; a ram appears and is slaughtered in Isaac's stead, as God commends Abraham's pious obedience. In addition to being addressed by modern scholarship, this biblical episode has been the focus of a great deal of commentary in traditional sources of Judaism, Christianity, and Islam. Biblical narrative According to the Hebrew Bible, God commands Abraham to offer his son Isaac as a sacrifice. After Isaac is bound to an altar, a messenger from God stops Abraham before the sacrifice finishes, saying "now I know you fear God". Abraham looks up and sees a ram and sacrifices it instead of Isaac. The passage states that the event occurred at "the mount of the " in "the land of Moriah". 2 Ch ...

Life Extension
Life extension is the concept of extending the human life expectancy, lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled oldest people, limit of 125 years. Several researchers in the area, along with "life extensionists", "immortalists" or "longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation (aging), rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals and organ (anatomy), organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans (agerasia) through complete rejuvenation to a healthy youthful condition. The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists. The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnum Opus
A masterpiece, ''magnum opus'' (), or ''chef-d’œuvre'' (; ; ) in modern use is a creation that has been given much critical praise, especially one that is considered the greatest work of a person's career or a work of outstanding creativity, skill, profundity, or workmanship. Historically, a "masterpiece" was a work of a very high standard produced to obtain membership of a guild or academy in various areas of the visual arts and crafts. Etymology The form ''masterstik'' is recorded in English or Scots in a set of Aberdeen guild regulations dated to 1579, whereas "masterpiece" is first found in 1605, already outside a guild context, in a Ben Jonson play. "Masterprize" was another early variant in English. In English, the term rapidly became used in a variety of contexts for an exceptionally good piece of creative work, and was "in early use, often applied to man as the 'masterpiece' of God or Nature". History Originally, the term ''masterpiece'' referred to a piece of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Hole
A black hole is a region of spacetime where gravitation, gravity is so strong that nothing, including light or other Electromagnetic radiation, electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary (topology), boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with thermal radiation, the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly. Obje ...

Interstellar War
An interstellar war is a hypothetical space war between combatants from different planetary systems. The concept provides a common plot device in science fiction, especially in the space opera subgenre. In contrast, the term ''intergalactic war'' refers to war between combatants from different galaxies, and ''interplanetary war'' refers to war between combatants from different planets of the same planetary system. Likelihood Michael H. Hart argued that if humans ever spread to other planetary systems, the actual likelihood of interstellar war would be low due to the immense distances (and hence travel times involved)—interstellar war would require a vastly greater investment of time and resources than present-day intraplanetary wars involve. By contrast, Robert Freitas argued that the energy expenditure required for interstellar war would be trivial from the viewpoint of a Type II or Type III civilisation on the Kardashev scale.

Moneta
In Roman mythology, Moneta (Latin Monēta) was a title given to two separate goddesses: It was the name of the goddess of memory (identified with the Greek goddess Mnemosyne), and it was an epithet of Juno, called Juno Moneta (Latin Iūno Monēta). The latter's name is the source of numerous words in English and the Romance languages, including “money" and "mint". The cult of the goddess Moneta was established largely under the influence of Greek religion, which featured the cult of Mnemosyne ("Μνημοσύνη"), the goddess of memory and the mother of the Muses. The goddess's name is derived from Latin ''monēre'' (which means to remind, warn, or instruct). She is mentioned in a fragment of Livius Andronicus' Latin Odyssey: ''Nam diva Monetas filia docuit'' ("since the divine daughter of Moneta has taught...", frg. 21 Büchner), which may be the equivalent of either Od. 8,480-1 or 488. The epithet Moneta that was given to Juno, in contrast, is more likely to have derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars In Fiction
Mars, the fourth planet from the Sun, has appeared as a Setting (narrative), setting in works of fiction since at least the mid-1600s. It became the most popular celestial object in fiction in the late 1800s as the Moon was evidently lifeless. At the time, the predominant genre depicting Mars was utopian fiction. Contemporaneously, the mistaken belief that there are canals on Mars emerged and made its way into fiction. ''The War of the Worlds'', H. G. Wells' story of an alien invasion of Earth by sinister Martians, was published in 1897 and went on to have a large influence on the science fiction genre. Life on Mars appeared frequently in fiction throughout the first half of the 1900s. Apart from enlightened as in the utopian works from the turn of the century, or evil as in the works inspired by Wells, Extraterrestrial intelligence, intelligent and human-like Martians also began to be depicted as decadent, a portrayal that was popularized by Edgar Rice Burroughs in the ''Barsoom ...

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been d ...
