After Doomsday
''After Doomsday'' is a science fiction novel by American writer Poul Anderson. It was published as a complete novel in 1962, having been serialized as ''The Day after Doomsday'' in the magazine ''Galaxy'', between December 1961 and February 1962. Plot introduction The novel explores events after the destruction of Earth, from the point of view of two returning starship crews, one entirely made up of men, the other consisting entirely of women. The story is set in the early 21st century. Even as the Cold War dragged on, Earth has been suddenly contacted by the Monwaingi space-faring culture. The technology of interstellar travel is spreading across the galaxy, disrupting one culture after another. Monwaing itself was contacted only a few centuries previously. Another culture, the Vorlak, underwent a transition from a stable planetary society to a warlord culture similar to the Japanese Shogunate. The nomadic Kandemirian culture became a hegemonistic one similar to the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poul Anderson
Poul William Anderson (November 25, 1926 – July 31, 2001) was an American fantasy and science fiction author who was active from the 1940s until the 21st century. Anderson wrote also historical novels. His awards include seven Hugo Awards and three Nebula Awards. Biography Poul Anderson was born on November 25, 1926, in Bristol, Pennsylvania to Scandinavian parents. Soon after his birth, his father, Anton Anderson relocated the family to Texas, where they lived for more than ten years. After Anton Anderson's death, his widow took the children to Denmark. The family returned to the United States after the beginning of World War II, settling eventually on a Minnesota farm. While he was an undergraduate student at the University of Minnesota, Anderson's first stories were published by editor John W. Campbell in the magazine ''Astounding Science Fiction'': "Tomorrow's Children" by Anderson and F. N. Waldrop in March 1947 and a sequel, "Chain of Logic" by Anderson alone, in July ...

Space Trade
Space trade is interplanetary or interstellar trade. Plans and ideas on how trade functions have been published by Futurists and pundits since the 1960s, though science fiction writers have been envisioning such trade for several more decades. Reality Though the existence of interstellar trade is unknown, there are several theories developed by well known economists such as Paul Krugman on how trade calculations and interest rates would have to be adjusted in such a circumstance. At very high velocities, for example a space station traveling at significant speeds relative to the speed of light, there will be time dilation. In 2004 Espen Gaarder Haug published a technical research article in ''Wilmott Magazine'' on how interest rates and securities calculations had to be adjusted for very high velocities to avoid arbitrage. He published similar theories on what he called "SpaceTime Finance" in a book published in 2007 titled ''Derivatives Models on Models''. Paul Krugman, winner ...

1962 American Novels
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Clan
A clan is a group of people united by actual or perceived kinship and descent. Even if lineage details are unknown, clans may claim descent from founding member or apical ancestor. Clans, in indigenous societies, tend to be endogamous, meaning that their members can marry one another. Clans preceded more centralized forms of community organization and government, and exist in every country. Members may identify with a coat of arms or other symbol to show that they are an . Kinship-based groups may also have a symbolic ancestor, whereby the clan shares a "stipulated" common ancestor who serves as a symbol of the clan's unity. Etymology The English word "clan" is derived from old Irish meaning "children", "offspring", "progeny" or "descendants"; it is not from the word for "family" or "clan" in either Irish or Scottish Gaelic. According to the ''Oxford English Dictionary'', the word "clan" was introduced into English in around 1425, as a descriptive label for the organization ...

Serbia
Serbia (, ; Serbian language, Serbian: , , ), officially the Republic of Serbia (Serbian language, Serbian: , , ), is a landlocked country in Southeast Europe, Southeastern and Central Europe, situated at the crossroads of the Pannonian Basin and the Balkans. It shares land borders with Hungary to the north, Romania to the northeast, Bulgaria to the southeast, North Macedonia to the south, Croatia and Bosnia and Herzegovina to the west, and Montenegro to the southwest, and claims a border with Albania through the Political status of Kosovo, disputed territory of Kosovo. Serbia without Kosovo has about 6.7 million inhabitants, about 8.4 million if Kosvo is included. Its capital Belgrade is also the List of cities in Serbia, largest city. Continuously inhabited since the Paleolithic Age, the territory of modern-day Serbia faced Slavs#Migrations, Slavic migrations in the 6th century, establishing several regional Principality of Serbia (early medieval), states in the early Mid ...

Ludwig Van Beethoven
Ludwig van Beethoven (baptised 17 December 177026 March 1827) was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western music; his works rank amongst the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era in classical music. His career has conventionally been divided into early, middle, and late periods. His early period, during which he forged his craft, is typically considered to have lasted until 1802. From 1802 to around 1812, his middle period showed an individual development from the styles of Joseph Haydn and Wolfgang Amadeus Mozart, and is sometimes characterized as heroic. During this time, he began to grow increasingly deaf. In his late period, from 1812 to 1827, he extended his innovations in musical form and expression. Beethoven was born in Bonn. His musical talent was obvious at an early age. He was initially harshly and intensively tau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biota (ecology)
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its c ...

Disinformation
Disinformation is false information deliberately spread to deceive people. It is sometimes confused with misinformation, which is false information but is not deliberate. The English word ''disinformation'' comes from the application of the Latin prefix ''dis-'' to ''information'' making the meaning "reversal or removal of information". The rarely used word had appeared with this usage in print at least as far back as 1887. Some consider it a loan translation of the Russian ''dezinformatsiya'', derived from the title of a KGB black propaganda department. Defector Ion Mihai Pacepa claimed Joseph Stalin coined the term, giving it a French-sounding name to claim it had a Western origin. Russian use began with a "special disinformation office" in 1923. Disinformation was defined in '' Great Soviet Encyclopedia'' (1952) as "false information with the intention to deceive public opinion". Operation INFEKTION was a Soviet disinformation campaign to influence opinion that the U. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quatrain
A quatrain is a type of stanza, or a complete poem, consisting of four lines. Existing in a variety of forms, the quatrain appears in poems from the poetic traditions of various ancient civilizations including Persia, Ancient India, Ancient Greece, Ancient Rome, and China, and continues into the 21st century, where it is seen in works published in many languages. This form of poetry has been continually popular in Iran since the medieval period, as Ruba'is form; an important faction of the vast repertoire of Persian poetry, with famous poets such as Omar Khayyam and Mahsati Ganjavi of Seljuk Persia writing poetry only in this format. Michel de Nostredame (Nostradamus) used the quatrain form to deliver his famous prophecies in the 16th century. There are fifteen possible rhyme schemes, but the most traditional and common are ABAA, AAAA, ABAB, and ABBA. Forms *The heroic stanza or elegiac stanza consists of the iambic pentameter, with the rhyme scheme of ABAB or AABB. An e ...

Coup De Grâce
A coup de grâce (; 'blow of mercy') is a death blow to end the suffering of a severely wounded person or animal. It may be a mercy killing of mortally wounded civilians or soldiers, friends or enemies, with or without the sufferer's consent. Methods Examples of coup de grâce include shooting the heart or head (typically the back of the skull) of a wounded, but still living, person during an execution or by humanely killing a suffering, mortally wounded soldier, in war, for whom medical aid is not available. In pre-firearms eras the wounded were finished with edged or impact weapons to include cutting throats, blows to the head, and thrusts to the heart. Other examples include the officer leading a firing squad administering a coup de grâce to the condemned with a pistol if the first hail of gunfire fails to kill the prisoner; or a ''kaishakunin'' who performs a beheading to quickly end a samurai's agony after seppuku. Other uses The phrase may also refer to the final even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interference Fringe
In physics, interference is a phenomenon in which two waves combine by adding their displacement together at every single point in space and time, to form a resultant wave of greater, lower, or the same amplitude. Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves, gravity waves, or matter waves. Etymology The word ''interference'' is derived from the Latin words ''inter'' which means "between" and ''fere'' which means "hit or strike", and was coined by Thomas Young in 1801. Mechanisms The principle of superposition of waves states that when two or more propagating waves of the same type are incident on the same point, the resultant amplitude at that point is equal to t ...

Standing Wave
In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with respect to time, and the oscillations at different points throughout the wave are in phase. The locations at which the absolute value of the amplitude is minimum are called nodes, and the locations where the absolute value of the amplitude is maximum are called antinodes. Standing waves were first noticed by Michael Faraday in 1831. Faraday observed standing waves on the surface of a liquid in a vibrating container. Franz Melde coined the term "standing wave" (German: ''stehende Welle'' or ''Stehwelle'') around 1860 and demonstrated the phenomenon in his classic experiment with vibrating strings. This phenomenon can occur because the medium is moving in the direction opposite to the movement of the wave, or it can arise in a stationary medium ...
