Positronic
A positronic brain is a fictional technological device, originally conceived by science fiction writer Isaac Asimov. It functions as a central processing unit (CPU) for robots, and, in some unspecified way, provides them with a form of consciousness recognizable to humans. When Asimov wrote his first robot stories in 1939 and 1940, the positron was a newly discovered particle, and so the buzz word "positronic" added a scientific connotation to the concept. Asimov's 1942 short story " Runaround" elaborates his fictional Three Laws of Robotics, which are ingrained in the positronic brains of nearly all of his robots. Conceptual overview Asimov remained vague about the technical details of positronic brains except to assert that their substructure was formed from an alloy of platinum and iridium. They were said to be vulnerable to radiation and apparently involve a type of volatile memory (since robots in storage required a power source keeping their brains "alive"). The focus of ...

Isaac Asimov
Isaac Asimov ( ; 1920 – April 6, 1992) was an American writer and professor of biochemistry at Boston University. During his lifetime, Asimov was considered one of the "Big Three" science fiction writers, along with Robert A. Heinlein and Arthur C. Clarke. A prolific writer, he wrote or edited more than 500 books. He also wrote an estimated 90,000 letters and postcards. Best known for his hard science fiction, Asimov also wrote mystery fiction, mysteries and fantasy, as well as much nonfiction. Asimov's most famous work is the ''Foundation series, Foundation'' series, the first three books of which won the one-time Hugo Award for "Best All-Time Series" in 1966. His other major series are the ''Galactic Empire series, Galactic Empire'' series and the ''Robot series, Robot'' series. The ''Galactic Empire'' novels are set in the much earlier history of the same fictional universe as the ''Foundation'' series. Later, with ''Foundation and Earth'' (1986), he linked this distant ...

Isaac Asimov's Caliban
The ''Robot'' series is a series of 37 science fiction short stories and six novels by American writer Isaac Asimov, featuring positronic robots. Later, Asimov would merge the ''Robot'' series with his ''Foundation'' series. Robot novels and stories The series started in 1940, with the story " Robbie" in the September 1940 '' Super Science Stories'' (appearing under the title "Strange Playfellow", which was not Asimov's title). Although it was originally written as a stand-alone story, the following year Asimov published a series of additional robot stories, which fit together into a narrative that was then put together as the book '' I, Robot''. List of works in the Robot series, in chronological order by narrative # '' I, Robot'' (1950) and later collections: '' The Complete Robot'' (1982), '' Robot Dreams'' (1986), '' Robot Visions'' (1990), and '' Gold'' (1995). #* In 1964, '' The Rest of the Robots'' was published - all of the short stories in that collection are ...

Zeroth Law Of Robotics
The Three Laws of Robotics (often shortened to The Three Laws or known as Asimov's Laws) are a set of rules devised by science fiction author Isaac Asimov. The rules were introduced in his 1942 short story " Runaround" (included in the 1950 collection ''I, Robot''), although they had been foreshadowed in some earlier stories. The Three Laws, quoted from the "Handbook of Robotics, 56th Edition, 2058 A.D.", are: ;First Law :A robot may not injure a human being or, through inaction, allow a human being to come to harm. ;Second Law :A robot must obey the orders by human beings except where such orders would conflict with the First Law. ;Third Law :A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. These form an organizing principle and unifying theme for Asimov's robotic-based fiction, appearing in his ''Robot'' series, the stories linked to it, and his ''Lucky Starr'' series of young-adult fiction. The Laws are inco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positron
The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 '' e'', a spin of 1/2 (the same as the electron), and the same mass as an electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the production of two or more photons. Positrons can be created by positron emission radioactive decay (through weak interactions), or by pair production from a sufficiently energetic photon which is interacting with an atom in a material. History Theory In 1928, Paul Dirac published a paper proposing that electrons can have both a positive and negative charge. This paper introduced the Dirac equation, a unification of quantum mechanics, special relativity, and the then-new concept of electron spin to explain the Zeeman effect. The paper did not explicitly predict a new particle but did allow for electrons having either positive or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robots And Empire
''Robots and Empire'' is a science fiction novel by the American author Isaac Asimov, published by Doubleday Books in 1985. It is part of Asimov's ''Robot'' series, which consists of many short stories (collected in '' I, Robot'', '' The Rest of the Robots'', '' The Complete Robot'', '' Robot Dreams'', '' Robot Visions'', and ''Gold'') and five novels (including '' The Positronic Man'', ''The Caves of Steel'', '' The Naked Sun'', and ''The Robots of Dawn''). ''Robots and Empire'' is part of Asimov's consolidation of his three major series of science fiction stories and novels into a single future history: his ''Robot'' series, his ''Galactic Empire'' series and his ''Foundation'' series. (Asimov also carried out this unification in '' Foundation's Edge'' and its sequel.) In the novel, Asimov depicts the transition from his earlier Milky Way Galaxy, inhabited by both human beings and positronic robots, to his Galactic Empire.

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting poin ...

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 quot ...

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 *Developing appropriate lesson plans for teaching AI targeted skills *Create guides to help the AI through the learning process *Address any maladaptive machine behaviors *R ...

Bottleneck
Bottleneck literally refers to the narrowed portion (neck) of a bottle near its opening, which limit the rate of outflow, and may describe any object of a similar shape. The literal neck of a bottle was originally used to play what is now known as slide guitar. Metaphorically, the term may also be used as an analogy for any of the following implications of rate limitation or function restriction: Computing * Bottleneck (network), in communication networks using max-min fairness * Bottleneck (software), a software component that severely affects application performance * Internet bottleneck, when high usage slows the performance on the Internet at a particular point * Von Neumann bottleneck, a limit of throughput between a computer's processor and memory * Interconnect bottleneck Geography * Bottleneck (K2), a mountain feature near the top of K2 mountain * Choke point, a feature that reduces passability of terrain * Free State Bottleneck, a quasi-state that existed in Germany du ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some ps ...
