Positronic Brain
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 o ...

Science Fiction
Science fiction (often shortened to sci-fi or abbreviated SF) is a genre of speculative fiction that deals with imaginative and futuristic concepts. These concepts may include information technology and robotics, biological manipulations, space exploration, time travel, Parallel universes in fiction, parallel universes, and extraterrestrials in fiction, extraterrestrial life. The genre often explores human responses to the consequences of projected or imagined scientific advances. Science fiction is related to fantasy (together abbreviated wikt:SF&F, SF&F), Horror fiction, horror, and superhero fiction, and it contains many #Subgenres, subgenres. The genre's precise Definitions of science fiction, definition has long been disputed among authors, critics, scholars, and readers. Major subgenres include hard science fiction, ''hard'' science fiction, which emphasizes scientific accuracy, and soft science fiction, ''soft'' science fiction, which focuses on social sciences.

Earth
Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering Water distribution on Earth, 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large Ice sheet, sheets of ice at Polar regions of Earth, Earth's polar polar desert, deserts retain more water than Earth's groundwater, lakes, rivers, and Water vapor#In Earth's atmosphere, atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's outer core, Earth has a liquid outer core that generates a ...

Fictional Computers
Fiction is any creative work, chiefly any narrative work, portraying individuals, events, or places that are imaginary or in ways that are imaginary. Fictional portrayals are thus inconsistent with fact, history, or plausibility. In a traditional narrow sense, fiction refers to written narratives in prose often specifically novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games. Definition and theory Typically, the fictionality of a work is publicly expressed, so the audience expects a work of fiction to deviate to a greater or lesser degree from the real world, rather than presenting for instance only factually accurate portrayals or characters who are actual people. Because fiction is generally understood as not adhering to the real world, the them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeroth Law Of Robotics
The Three Laws of Robotics (often shortened to The Three Laws or Asimov's Laws) are a set of rules devised by science fiction author Isaac Asimov, which were to be followed by robots in several of his stories. The rules were introduced in his 1942 short story " Runaround" (included in the 1950 collection ''I, Robot''), although similar restrictions had been implied in earlier stories. The Laws The Three Laws, presented to be from the fictional "Handbook of Robotics, 56th Edition, 2058 A.D.", are: # A robot may not injure a human being or, through inaction, allow a human being to come to harm. # A robot must obey the orders by human beings except where such orders would conflict with the First Law. # A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Use in fiction The Three Laws form an organizing principle and unifying theme for Asimov's robot-based fiction, appearing in his ''Robot'' series, the stories linked to ...

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. The galaxy of his earlier trilogy of ''Robot'' no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 A robot is a machine—especially one Computer program, programmable by a computer—capable of carrying out a complex series of actions Automation, automatically.

Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Psychology
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both consciousness, conscious and Unconscious mind, unconscious phenomena, and mental processes such as thoughts, feelings, and motivation, motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Biological psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as Behavioural sciences, behavioral or Cognitive science, cognitive scientists.

Science
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Ancient Egypt, Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
