T. Peter Brody
T. P. "Peter" Brody (18 April 1920 Budapest, Hungary – 18 September 2011 Pittsburgh, Pennsylvania, United States) was a British-naturalised physicist and the co-inventor of Active Matrix Thin-Film Transistor display technology together with Fang-Chen Luo, having produced the world's first Active Matrix Liquid Crystal Display (AM-LCD) in 1972 and the first functional AM-EL (electroluminescent display) in 1973 while employed by Westinghouse Electric Corporation in Pittsburgh. Brody coined the term "active matrix" and first used it in a published journal article in 1975. Early life and career From early childhood Brody was interested in sports, particularly swimming and rowing, and had a passion for classical music. In 1938 he left his parents and two younger brothers behind in Hungary to learn the family trade at the London College of Printing. He was naturalised as a British subject in January 1948. He served as a designer/draftsman and worked for the Special Operations Executi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Special Operations Executive
Special Operations Executive (SOE) was a British organisation formed in 1940 to conduct espionage, sabotage and reconnaissance in German-occupied Europe and to aid local Resistance during World War II, resistance movements during World War II. SOE personnel operated in all territories occupied or attacked by the Axis powers, except where demarcation lines were agreed upon with Britain's principal Allies of World War II, Allies, the United States and the Soviet Union. SOE made use of neutral territory on occasion, or made plans and preparations in case neutral countries were attacked by the Axis. The organisation directly employed or controlled more than 13,000 people, of whom 3,200 were women. Both men and women served as agents in Axis-occupied countries. The organisation was dissolved in 1946. A memorial to those who served in SOE was unveiled in 1996 on the wall of the west cloister of Westminster Abbey by the Queen Elizabeth The Queen Mother, Queen Mother, and in 2009 on t ...

Thin Film
A thin film is a layer of materials ranging from fractions of a nanometer ( monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, integrated passive devices, light-emitting diodes, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage ( thin-film bat ...

Pattern Recognition
Pattern recognition is the task of assigning a class to an observation based on patterns extracted from data. While similar, pattern recognition (PR) is not to be confused with pattern machines (PM) which may possess PR capabilities but their primary function is to distinguish and create emergent patterns. PR has applications in statistical data analysis, signal processing, image analysis, information retrieval, bioinformatics, data compression, computer graphics and machine learning. Pattern recognition has its origins in statistics and engineering; some modern approaches to pattern recognition include the use of machine learning, due to the increased availability of big data and a new abundance of processing power. Pattern recognition systems are commonly trained from labeled "training" data. When no labeled data are available, other algorithms can be used to discover previously unknown patterns. KDD and data mining have a larger focus on unsupervised methods and str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field Emission
Field electron emission, also known as field-induced electron emission, field emission (FE) and electron field emission, is the emission of electrons from a material placed in an electrostatic field. The most common context is field emission from a solid surface into a vacuum. However, field emission can take place from solid or liquid surfaces, into a vacuum, a fluid (e.g. air), or any non-conducting or weakly conducting dielectric. The field-induced promotion of electrons from the valence to conduction band of semiconductors (the Zener effect) can also be regarded as a form of field emission. Field emission in pure metals occurs in high electric fields: the gradients are typically higher than 1 gigavolt per metre and strongly dependent upon the work function. While electron sources based on field emission have a number of applications, field emission is most commonly an undesirable primary source of vacuum breakdown and electrical discharge phenomena, which engineers work to ...

Semiconductor
A semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be modified by adding impurities (" doping") to its crystal structure. When two regions with different doping levels are present in the same crystal, they form a semiconductor junction. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called " metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. Silicon is a critical element for fabricating most electronic circuits. Semiconductor devices can display a range of different useful properties, such as passing current more easil ...

Tunnel Diode
A tunnel diode or Esaki diode is a type of semiconductor diode that has effectively " negative resistance" due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki and Yuriko Kurose when working at Tokyo Tsushin Kogyo, now known as Sony. In the first public report of the discovery (presentation at the 12th annual meeting of the Physical Society of Japan in October 1957), Takashi Suzuki, who was a student at Tokyo University of Science and doing his internship at Tokyo Tsushin Kogyo under Esaki's supervision, was a co-author. Suzuki, along with Yuriko Kurose, first observed the negative differential resistance when they were testing heavily doped P-N junctions. In 1973, Esaki received the Nobel Prize in Physics for experimental demonstration of the electron tunneling effect in semiconductors. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tun ...

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict List of natural phenomena, natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabian Society
The Fabian Society () is a History of the socialist movement in the United Kingdom, British socialist organisation whose purpose is to advance the principles of social democracy and democratic socialism via gradualist and reformist effort in democracies, rather than by revolutionary overthrow. The Fabian Society was also historically related to some of the furthest left factions of Radicalism (historical), radicalism, a left-wing liberal tradition. As one of the founding organisations of the Labour Representation Committee (1900), Labour Representation Committee in 1900, and as an important influence upon the Labour Party (UK), Labour Party which grew from it, the Fabian Society has strongly influenced British politics. Members of the Fabian Society have included political leaders from other countries, such as Jawaharlal Nehru, who adopted Fabian principles as part of their own political ideologies. The Fabian Society founded the London School of Economics in 1895. Today, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
