Catch That Rabbit
"Catch that Rabbit" is a science fiction short story by American writer Isaac Asimov. It was first published in the February 1944 issue of '' Astounding Science Fiction'' and reprinted in the collections '' I, Robot'' (1950) and ''The Complete Robot'' (1982). Plot summary The recurring team of Powell and Donovan are testing a new model of robot on an asteroid mining station. This DV-5 (Dave) has six subsidiary robots, described as "fingers", which it controls via positronic fields, a means of transmission not yet fully understood by roboticists. When the humans are not in contact, the robot stops producing ore. It cannot recall the time periods when it stops mining, and states that it finds this just as puzzling as the humans do. Powell and Donovan secretly observe the robot without its knowledge. It starts performing strange marches and dances with its subsidiaries whenever something unexpected happens -an early example of a Heisenbug (software problem). To learn more, the ...

Powell And Donovan
The following is a list of characters in Isaac Asimov's ''Robot'' series. Kelden Amadiro Kelden Amadiro is a Spacer and the main antagonist in the novels ''The Robots of Dawn'' and ''Robots and Empire''. He is the head of the Robotics Institute on Aurora. He is known for being extremely against the expansion of Earth to other planets, and in the end even tries to destroy the Earth by speeding up the rate of radiation in its crust. His memory of this is erased by R. Giskard Reventlov and R. Daneel Olivaw; however they allow Levular Mandamus to destroy the Earth because his motives were more beneficial for humanity and were therefore allowable by the Zeroth Law of Robotics: since a slow increase in the rate of radiation would drive Earthpeople to the outer worlds, but a quick increase like Amadiro wanted, would kill the Earth with its population still on it. Milton Ashe Milton Ashe appears for a short time in Chapter 5 of ''I, Robot'' ("Liar!"). He is described as "the youngest o ...

Robot Series Short Stories By Isaac Asimov
A robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics. Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's ''Advanced Step in Innovative Mobility'' ( ASIMO) and TOSY's ''TOSY Ping Pong Playing Robot'' (TOPIO) to industrial robots, medical operating robots, patient assist robots, dog therapy robots, collectively programmed ''swarm'' robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic nano robots. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. Autonomous things are expected to proliferate i ...

Foundation Series
The ''Foundation'' series is a science fiction book series written by American author Isaac Asimov. First published as a series of short stories in 1942–50, and subsequently in three collections in 1951–53, for thirty years the series was a trilogy: '' Foundation''; '' Foundation and Empire''; and '' Second Foundation''. It won the one-time Hugo Award for "Best All-Time Series" in 1966. Asimov began adding new volumes in 1981, with two sequels: ''Foundation's Edge'' and '' Foundation and Earth'', and two prequels: '' Prelude to Foundation'' and ''Forward the Foundation''. The premise of the stories is that, in the waning days of a future Galactic Empire, the mathematician Hari Seldon spends his life developing a theory of psychohistory, a new and effective mathematics of sociology. Using statistical laws of mass action, it can predict the future of large populations. Seldon foresees the imminent fall of the Empire, which encompasses the entire Milky Way, and a Dark Age ...

Mania
Mania, also known as manic syndrome, is a mental and behavioral disorder defined as a state of abnormally elevated arousal, affect, and energy level, or "a state of heightened overall activation with enhanced affective expression together with lability of affect." During a manic episode, an individual will experience rapidly changing emotions and moods, highly influenced by surrounding stimuli. Although mania is often conceived as a "mirror image" to depression, the heightened mood can be either euphoric or dysphoric. As the mania intensifies, irritability can be more pronounced and result in anxiety or anger. The symptoms of mania include elevated mood (either euphoric or irritable), flight of ideas and pressure of speech, increased energy, decreased need and desire for sleep, and hyperactivity. They are most plainly evident in fully developed hypomanic states. However, in full-blown mania, they undergo progressively severe exacerbations and become more and more obscu ...

Hysteria
Hysteria is a term used colloquially to mean ungovernable emotional excess and can refer to a temporary state of mind or emotion. In the nineteenth century, hysteria was considered a diagnosable physical illness in women. It is assumed that the basis for diagnosis operated under the belief that women are predisposed to mental and behavioral conditions; an interpretation of sex-related differences in stress responses. In the twentieth century, it shifted to being considered a mental illness. Many influential people such as Sigmund Freud and Jean-Martin Charcot dedicated research to hysteria patients. Currently, most doctors practicing medicine do not accept hysteria as a medical diagnosis. The blanket diagnosis of hysteria has been fragmented into myriad medical categories such as epilepsy, histrionic personality disorder, conversion disorders, dissociative disorders, or other medical conditions. Furthermore, lifestyle choices, such as choosing not to wed, are no longer cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Susan Calvin
Dr. Susan Calvin is a fictional character appearing in Isaac Asimov's ''Robot'' series of science fiction short stories. According to I, Robot, Susan Calvin was born in the year 1982 and died at the age of 82, either in 2064 or 2065. She was the chief robopsychologist at US Robots and Mechanical Men, Inc., posited as the major manufacturer of robots in the 21st century. She was the main character in many of Asimov's short stories concerning robots, which were later collected in the books ''I, Robot'' and ''The Complete Robot''. Fictional character biography According to Asimov's fictional history of robotics, Susan Calvin was born in 1982, the same year that US Robots and Mechanical Men was incorporated. At 16, she wrote the first of many papers on robotics, a Physics-1 paper entitled "Practical Aspects of Robotics". This was after attending a Psycho-Math seminar at which Dr Alfred Lanning of US Robots demonstrated the first mobile robot to be equipped with a voice. As quoted ...

Robopsychology
Robopsychology is the study of the personalities and behavior of intelligent machines. The term was coined by Isaac Asimov in the short stories collected in ''I, Robot'', which featured robopsychologist Dr. Susan Calvin, and whose plots largely revolved around the protagonist solving problems connected with intelligent robot behaviour. The term has been also used in some academic studies from the field of psychology and human–computer interactions, and it refers to the study of the psychological consequences of living in societies where the application of robotics is becoming increasingly common. In real life Andrea Kuszewski, a self-described robopsychologist gives the following examples of potential responsibilities for a robopsychologist in Discover. *"Assisting in the design of cognitive architectures A cognitive architecture refers to both a theory about the structure of the human mind and to a computational instantiation of such a theory used in the fields of artificial ...

Thumb Twiddling
Thumb twiddling is an activity that is done with the hands of an individual whereby the fingers are interlocked and the thumbs circle around a common point, usually in the middle of the distance between the two thumbs. While it is an expression of at least a moderate amount of manual dexterity, thumb twiddling is frequently used as an example of a useless, time-wasting activity. Medical uses Thumb twiddling can be used as a simple test for manual dexterity. Contra-rotating thumbs Contra-rotation Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Examples include some aircraft propellers, res ... involves moving the thumbs in opposing directions. While thumb twiddling comes naturally for almost everyone, it is extremely rare for people to be able to naturally contra-rotate their thumbs without spending a significant amount of t ...

Anthropomorphism
Anthropomorphism is the attribution of human traits, emotions, or intentions to non-human entities. It is considered to be an innate tendency of human psychology. Personification is the related attribution of human form and characteristics to abstract concepts such as nations, emotions, and natural forces, such as seasons and weather. Both have ancient roots as storytelling and artistic devices, and most cultures have traditional fables with anthropomorphized animals as characters. People have also routinely attributed human emotions and behavioral traits to wild as well as domesticated animals. Etymology Anthropomorphism and anthropomorphization derive from the verb form ''anthropomorphize'', itself derived from the Greek ''ánthrōpos'' (, "human") and ''morphē'' (, "form"). It is first attested in 1753, originally in reference to the heresy of applying a human form to the Christian God.''Oxford English Dictionary'', 1st ed. "anthropomorphism, ''n.''"

Heisenbug
In computer programming jargon, a heisenbug is a software bug that seems to disappear or alter its behavior when one attempts to study it. The term is a pun on the name of Werner Heisenberg, the physicist who first asserted the observer effect of quantum mechanics, which states that the act of observing a system inevitably alters its state. In electronics, the traditional term is probe effect, where attaching a test probe to a device changes its behavior. Similar terms, such as ''bohrbug'', ''mandelbug'', ''hindenbug'', and ''schrödinbug'' (see the section on related terms) have been occasionally proposed for other kinds of unusual software bugs, sometimes in jest. Examples Heisenbugs occur because common attempts to debug a program, such as inserting output statements or running it with a debugger, usually have the side-effect of altering the behavior of the program in subtle ways, such as changing the memory addresses of variables and the timing of its execution.
