Gateway (novel)
''Gateway'' is a 1977 science-fiction novel by American writer Frederik Pohl. It is the opening novel in the Heechee saga, with four sequels that followed (five books overall). ''Gateway'' won the 1978 Hugo Award for Best Novel, the 1978 Locus Award for Best Novel, the 1977 Nebula Award for Best Novel, and the 1978 John W. Campbell Memorial Award for Best Science Fiction Novel. The novel was adapted into a computer game in 1992. Publishing history ''Gateway'' was serialized in ''Galaxy'' prior to its hardcover publication. A short concluding chapter, cut before publication, was later published in the August 1977 issue of ''Galaxy''. Plot summary Gateway is an asteroid hollowed out by the Heechee, a long-vanished alien race. Humans have had limited success understanding the left-behind bits of Heechee technology found there and elsewhere.

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 ...

Analog Science Fiction/Science Fact
''Analog Science Fiction and Fact'' is an American science fiction magazine published under various titles since 1930. Originally titled ''Astounding Stories of Super-Science'', the first issue was dated January 1930, published by William Clayton, and edited by Harry Bates. Clayton went bankrupt in 1933 and the magazine was sold to Street & Smith. The new editor was F. Orlin Tremaine, who soon made ''Astounding'' the leading magazine in the nascent pulp science fiction field, publishing well-regarded stories such as Jack Williamson's '' Legion of Space'' and John W. Campbell's "Twilight". At the end of 1937, Campbell took over editorial duties under Tremaine's supervision, and the following year Tremaine was let go, giving Campbell more independence. Over the next few years Campbell published many stories that became classics in the field, including Isaac Asimov's ''Foundation'' series, A. E. van Vogt's ''Slan'', and several novels and stories by Robert A. Heinle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metagaming Concepts
Metagaming Concepts, later known simply as Metagaming, was a company that published board games from 1974 to 1983. It was founded and owned by Howard Thompson, who designed the company's first game, ''Stellar Conquest''. The company also invented Microgames and published Steve Jackson's first designs, including ''Ogre'', '' G.E.V.'' and ''The Fantasy Trip''. History The company's first product, released in 1974, was ''Stellar Conquest'', which had been rejected by Avalon Hill in 1973. Many of Metagaming's notable titles were also science fiction wargames, including ''Ogre'', '' G.E.V.'', and '' WarpWar''. In 1975, Metagaming started ''The Space Gamer'' as a quarterly house magazine. By its 17th issue, ''TSG'' was a full size bimonthly magazine, printed on slick paper and covering games from other publishers, including fantasy games. Thompson and Metagaming pioneered the idea of publishing small, low-cost games in what came to be known as the MicroGame format. For a while, Me ...

The Space Gamer
''The Space Gamer'' was a magazine dedicated to the subject of science fiction and fantasy board games and tabletop role-playing games. It quickly grew in importance and was an important and influential magazine in its subject matter from the late 1970s through the mid-1980s. The magazine is no longer published, but the rights holders maintain a web presence using its final title ''Space Gamer/Fantasy Gamer''.

Gravitational Time Dilation
Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational potential increases (the clock getting away from the source of gravitation). Albert Einstein originally predicted this effect in his theory of relativity and it has since been confirmed by tests of general relativity. This has been demonstrated by noting that atomic clocks at differing altitudes (and thus different gravitational potential) will eventually show different times. The effects detected in such Earth-bound experiments are extremely small, with differences being measured in nanoseconds. Relative to Earth's age in billions of years, Earth's core is effectively 2.5 years younger than its surface. Demonstrating larger effects would re ...

Psychoanalysis
PsychoanalysisFrom Greek: + . is a set of theories and therapeutic techniques"What is psychoanalysis? Of course, one is supposed to answer that it is many things — a theory, a research method, a therapy, a body of knowledge. In what might be considered an unfortunately abbreviated description, Freud said that anyone who recognizes transference and resistance is a psychoanalyst, even if he comes to conclusions other than his own.… I prefer to think of the analytic situation more broadly, as one in which someone seeking help tries to speak as freely as he can to someone who listens as carefully as he can with the aim of articulating what is going on between them and why. David Rapaport (1967a) once defined the analytic situation as carrying the method of interpersonal relationship to its last consequences."

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...

Repression (psychology)
Repression is a key concept of psychoanalysis, where it is understood as a defence mechanism that "ensures that what is unacceptable to the conscious mind, and would if recalled arouse anxiety, is prevented from entering into it." According to psychoanalytic theory, repression plays a major role in many mental illnesses, and in the psyche of the average person.Laplanche pp. 390, 392 There has been debate as to whether (or how often) memory repression really occurs and mainstream psychology holds that true memory repression occurs infrequently. American psychologists began to attempt to study repression in the experimental laboratory around 1930. However, psychoanalysts were at first uninterested in attempts to study repression in laboratory settings, and later came to reject them. Most psychoanalysts concluded that such attempts misrepresented the psychoanalytic concept of repression. Sigmund Freud's theory As Sigmund Freud moved away from hypnosis, and towards urging his patient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Survivor Guilt
Survivor guilt (or survivor's guilt; also called survivor syndrome or survivor's syndrome and survivor disorder or survivor's disorder) is a mental condition that occurs when a person believes they have done something wrong by surviving a traumatic or tragic event when others could not. The experience and manifestation of survivor's guilt will depend on an individual's psychological profile. When the ''Diagnostic and Statistical Manual of Mental Disorders IV'' (DSM-IV) was published, survivor guilt was removed as a recognized specific diagnosis, and redefined as a significant symptom of post-traumatic stress disorder (PTSD). History Survivor guilt was first identified during the 1960s. Several therapists recognized similar if not identical conditions among Holocaust survivors. Similar signs and symptoms have been recognized in survivors of traumatic situations including combat, natural disasters, terrorist attacks, air-crashes and wide-ranging job layoffs. A variant form has been ... [...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 ...

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...
