Philo Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971), "The father of television", was the American inventor and pioneer who was granted the first patent for the television by the United States Government. Burns, R. W. (1998), ''Television: An international history of the formative years''. IET History of Technology Series, 22. LondonThe Institution of Engineering and Technology (IET) p. 370. . He also invented a video camera tube, and the image dissector. He commercially produced and sold a fully functioning television system, complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons. The desi ...

Sketch (drawing)
A sketch (ultimately from Greek language, Greek σχέδιος – ''schedios'', "done extempore") is a rapidly executed freehand drawing that is not usually intended as a finished work.Diana Davies (editor), ''Harrap's Illustrated Dictionary of Art and Artists'', Harrap Books Limited, (1990) A sketch may serve a number of purposes: it might record something that the artist sees, it might record or develop an idea for later use or it might be used as a quick way of graphically demonstrating an image, idea or principle. Sketching is the most inexpensive art medium. Sketches can be made in any drawing medium. The term is most often applied to graphic work executed in a dry medium such as silverpoint, graphite, pencil, charcoal or pastel. It may also apply to drawings executed in pen and ink, digital input such as a digital pen, ballpoint pen, marker pen, Watercolor painting, water colour and oil paint. The lat ...

Physics
Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...) You will come to see physics as a towering achievement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during chemical reaction, reactions with other chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the prop ...

Pulp Magazine
Pulp magazines (also referred to as "the pulps") were inexpensive fiction magazines that were published from 1896 until around 1955. The term "pulp" derives from the Pulp (paper), wood pulp paper on which the magazines were printed, due to their cheap nature. In contrast, magazines printed on higher-quality paper were called "glossies" or "slicks". The typical pulp magazine had 128 pages; it was wide by high, and thick, with ragged, untrimmed edges. Pulps were the successors to the penny dreadfuls, dime novels, and short-fiction magazines of the 19th century. Although many respected writers wrote for pulps, the magazines were best known for their lurid, exploitation fiction, exploitative, and sensational subject matter, even though this was but a small part of what existed in the pulps. Digest magazines and men's adventure magazines were incorrectly regarded as pulps, though they have different editorial and production standards and are instead replacements. Modern superhero Su ...

Armature (electrical Engineering)
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The armature windings conduct Alternating current, AC even on Direct current, DC machines, due to the Commutator (electric), commutator action (which periodically reverses current direction) or due to electronic commutation, as in Brushless DC electric motor, brushless DC motors. The armature can be on either the Rotor (electric), rotor (rotating part) or the stator (field coil, stationary part), depending on the type of electric machine. Shapes of Armature (electrical engineering), armature used in motors include double-T and triple-T armatures. The armature windings interact with the magnetic field (magnetic flux) in the air-gap; the magnetic field is generated either by permanent magnets, or electromagnets formed by a conducting coil. The armature must carry electric current, current, so it is always a electrical conductor, conductor or a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
