Wonder Stories
''Wonder Stories'' was an early American science fiction magazine which was published under several titles from 1929 to 1955. It was founded by Hugo Gernsback in 1929 after he had lost control of his first science fiction magazine, ''Amazing Stories'', when his media company Experimenter Publishing went bankrupt. Within a few months of the bankruptcy, Gernsback launched three new magazines: ''Air Wonder Stories'', ''Science Wonder Stories'', and ''Science Wonder Quarterly''. ''Air Wonder Stories'' and ''Science Wonder Stories'' were merged in 1930 as ''Wonder Stories'', and the quarterly was renamed ''Wonder Stories Quarterly''. The magazines were not financially successful, and in 1936 Gernsback sold ''Wonder Stories'' to Ned Pines at Beacon Publications, where, retitled ''Thrilling Wonder Stories'', it continued for nearly 20 years. The last issue was dated Winter 1955, and the title was then merged with '' Startling Stories'', another of Pines' science fiction magazines. ...

Any natural process that is not completely random, and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete Sign (semiotics), signs to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and current (fluid), currents convey information in a more continuous form. Information is not knowledge itself, but the meaning (philosophy), meaning that may be derived from a representation (mathematics), r ...

Donald E. Lancaster is an American author, inventor, and microcomputer pioneer. Background Lancaster is a writer and engineer, who authored multiple articles for computer and electronics magazines of the 1970s, including ''Popular Electronics'', ''Radio Electronics'', ''Dr. Dobb's Journal'', '' 73 Magazine'', and ''Byte''. He has written books on electronics, computers, and entrepreneurship, both commercially published and self-published. An early project was his "TV Typewriter" dumb terminal. This design was accepted by early microcomputer users as it used an ordinary television set for the display, and could be built with around US $200 in parts, at a time when commercial terminals were selling for over US $1,000. Lancaster was an early advocate and developer of what is now known as print-on-demand technology. Lancaster produced his self-published books by re-purposing the game port of an Apple II to transfer PostScript code directly to a laser printer, rather than using a ...

North Country Radio
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Electronics Cover August 1949
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Almost All Digital Electronics
In set theory, when dealing with sets of infinite size, the term almost or nearly is used to refer to all but a negligible amount of elements in the set. The notion of "negligible" depends on the context, and may mean "of measure zero" (in a measure space), "finite" (when infinite sets are involved), or "countable" (when uncountably infinite sets are involved). For example: *The set S = \ is almost \mathbb for any k in \mathbb, because only finitely many natural numbers are less than ''k''. *The set of prime numbers is not almost \mathbb, because there are infinitely many natural numbers that are not prime numbers. *The set of transcendental numbers are almost \mathbb, because the algebraic real numbers form a countable subset of the set of real numbers (which is uncountable). *The Cantor set is uncountably infinite, but has Lebesgue measure zero. So almost all real numbers in (0, 1) are members of the complement of the Cantor set. See also *Almost all *Almost sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feminist Movement
The feminist movement (also known as the women's movement, or feminism) refers to a series of social movements and political campaigns for Radical politics, radical and Liberalism, liberal reforms on women's issues created by the inequality between men and women.
