Moravec (robot)
''Ilium/Olympos'' is a series of two science fiction novels by Dan Simmons. The events are set in motion by beings who appear to be ancient Greek gods. Like Simmons' earlier series, the Hyperion Cantos, it is a form of "literary science fiction"; it relies heavily on intertextuality, in this case with Homer and Shakespeare as well as references to Marcel Proust's ''À la recherche du temps perdu'' (or ''In Search of Lost Time'') and Vladimir Nabokov's novel '' Ada or Ardor: A Family Chronicle''. As with most of his science fiction and in particular with '' Hyperion'', '' Ilium'' demonstrates that Simmons writes in the soft science fiction tradition of Ray Bradbury and Ursula K. Le Guin. ''Ilium'' is based on a literary approach similar to most of Bradbury's work, but describes larger segments of society and broader historical events. As in Le Guin's Hainish series, Simmons places the action of ''Ilium'' in a vast and complex universe made of relatively plausible technological an ...

Science Fiction
Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, extraterrestrial life, sentient artificial intelligence, cybernetics, certain forms of immortality (like mind uploading), and the singularity. Science fiction predicted several existing inventions, such as the atomic bomb, robots, and borazon, whose names entirely match their fictional predecessors. In addition, science fiction might serve as an outlet to facilitate future scientific and technological innovations. Science fiction can trace its roots to ancient mythology. It is also related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers. Science fiction, in literature, film, television, and other media, has beco ...

Posthuman (Human Evolution)
Posthuman or post-human is a concept originating in the fields of science fiction, futurology, contemporary art, and philosophy that means a person or entity that exists in a state beyond being human. The concept aims at addressing a variety of questions, including ethics and justice, language and trans-species communication, social systems, and the intellectual aspirations of interdisciplinarity. Posthumanism is not to be confused with transhumanism (the biotechnological enhancement of human beings) and narrow definitions of the posthuman as the hoped-for transcendence of materiality. The notion of the posthuman comes up both in posthumanism as well as transhumanism, but it has a special meaning in each tradition. In 2017, Penn State University Press in cooperation with Stefan Lorenz Sorgner and James Hughes (sociologist), James Hughes established the ''Journal of Posthuman Studies'', in which all aspects of the concept "posthuman" can be analysed. Posthumanism In critical the ...

Cryogenics
In physics, cryogenics is the production and behaviour of materials at very low temperatures. The 13th IIR International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of “cryogenics” and “cryogenic” by accepting a threshold of 120 K (or –153 °C) to distinguish these terms from the conventional refrigeration. This is a logical dividing line, since the normal boiling points of the so-called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below 120K while the Freon refrigerants, hydrocarbons, and other common refrigerants have boiling points above 120K. The U.S. National Institute of Standards and Technology considers the field of cryogenics as that involving temperatures below -153 Celsius (120K; -243.4 Fahrenheit) Discovery of superconducting materials with critical temperatures significantly above the boiling point of nitrogen has provided new interest in reliable, low cost method ...

Wandering Jew
The Wandering Jew is a mythical immortal man whose legend began to spread in Europe in the 13th century. In the original legend, a Jew who taunted Jesus on the way to the Crucifixion was then cursed to walk the Earth until the Second Coming. The exact nature of the wanderer's indiscretion varies in different versions of the tale, as do aspects of his character; sometimes he is said to be a shoemaker or other tradesman, while sometimes he is the doorman at the estate of Pontius Pilate. Name An early extant manuscript containing the Legend is the ''Flores Historiarum'' by Roger of Wendover, where it appears in the part for the year 1228, under the title ''Of the Jew Joseph who is still alive awaiting the last coming of Christ''. The central figure is named ''Cartaphilus'' before being baptized later by Ananias as ''Joseph''. The root of the name ''Cartaphilus'' can be divided into ''kartos'' and ''philos'', which can be translated roughly as "dearly" and "loved", connecting the L ...

Limerence
Limerence is a state of mind which results from romantic or non-romantic feelings for another person, and typically includes intrusive, melancholic thoughts and/or tragic concerns for the object of one's affection as well as a desire to form or maintain a relationship with the object of love and to have one's feelings reciprocated. Limerence can also be defined as an involuntary state of intense desire. Definition Psychologist Dorothy Tennov coined the term "limerence" for her 1979 book, ''Love and Limerence: The Experience of Being in Love'', to describe a concept that had grown out of her work in the mid-1960s, when she interviewed over 500 people on the topic of love. Limerence, which is not exclusively sexual, has been defined in terms of its potentially inspirational effects and relation to attachment theory. It has been described as being "an involuntary potentially inspiring state of adoration and attachment to a limerent object (LO) involving intrusive and obsess ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...

Lepidopterist
Lepidopterology ()) is a branch of entomology concerning the scientific study of moths and the three superfamilies of butterflies. Someone who studies in this field is a lepidopterist or, archaically, an aurelian. Origins Post-Renaissance, the rise of the "lepidopterist" can be attributed to the expanding interest in science, nature and the surroundings. When Linnaeus wrote the tenth edition of the '' Systema Naturae'' in 1758, there was already "a substantial body of published work on Lepidopteran natural history" (Kristensen, 1999). These included: * ''Insectorum sive Minimorum Animalium Theatrum'' – Thomas Mouffet (1634) * ''Metamorphosis Naturalis'' – Jan Goedart (1662–67 ) * ''Metamorphosis insectorum Surinamensium'' – Maria S. Merian (1705), whose work included illustrated accounts of European Lepidoptera * ''Historia Insectorum'' – John Ray (1710) * ''Papilionum Brittaniae icones'' – James Petiver (1717) History Scholars 1758–1900 was the era of th ...

Incest Taboo
An incest taboo is any cultural rule or norm that prohibits sexual relations between certain members of the same family, mainly between individuals related by blood. All human cultures have norms that exclude certain close relatives from those considered suitable or permissible sexual or marriage partners, making such relationships taboo. However, different norms exist among cultures as to which blood relations are permissible as sexual partners and which are not. Sexual relations between related persons which are subject to the taboo are called incestuous relationships. Some cultures proscribe sexual relations between clan-members, even when no traceable biological relationship exists, while members of other clans are permissible irrespective of the existence of a biological relationship. In many cultures, certain types of cousin relations are preferred as sexual and marital partners, whereas in others these are taboo. Some cultures permit sexual and marital relations betwe ...

Reproduction
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce and organisms only pass on 50% of their genes.John Maynard Smith ''The Evolution of Sex'' 1978. Sexual reproduction typically requires the sexual interaction of two specializ ...

Sexual Intercourse
Sexual intercourse (or coitus or copulation) is a sexual activity typically involving the insertion and thrusting of the penis into the vagina for sexual pleasure or reproduction.Sexual intercourse most commonly means penile–vaginal penetration for sexual pleasure or sexual reproduction; dictionary sources state that it especially means this, and scholarly sources over the years agree. See, for example; * * * * * * * * * This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers) and penetration by use of a dildo (especially a strap-on dildo). These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding. Ther ...

Sperm
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one). Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia. Flowering plants contain non-motile sperm inside pollen, while some more basal plants like ferns and some gymnosperms have motile sperm. Sperm cells form during the process known as spermatogenesis, which in amniotes ( reptiles and mammals) takes place in the seminiferous tubules of the testes. This process involves the production of several successive sperm cell precursors, starting with spermatogonia, which differentiate into spermatocytes. The spermatocytes then undergo meiosis, reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, ...

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...
