Science and Technology Time Line

FEATURES: Focuses on the physical processes involved in electromagnetic fields and applications. Emphasizes the engineering relevance and use of electromagnetic theory -- in both the "theory" chapters and applications chapters. Uses a "classical," or "historical" approach which begins with low frequency field effects (electrostatics and magnetostatics), and leads later to the full time-varying effects. Motivates the mathematics with discussions that tell the reader where the discussion is going, how it will get there, and what the equations mean. Contains a broad overview chapter on Electromagnetic Sources, Forces, and Fields (Ch. 3) that explains what electric and magnetic fields are, in general, and how they are related to their sources. Discusses the classic electromagnetic experiments that were performed in the early history of electromagnetics, along with the laws that came from electromagnetic equations -- Maxwell's equations. Covers transmission lines before plane waves. This allows: Smoother, earlier coordination with laboratory experiments and measuring instruments that make heavy use of transmission lines. Earlier development of the relationship between electromagnetic theory and circuit theory. Arranges chapters on electrostatic fields and effects (Chs. 4-6) and those on magnetostatic fields and effects (Chs. 7-9) in parallel fashion; this organization presents the material in manageable units. Presents the curvilinear square techniques (flux plots) for graphically solving both electrostatic and magnetostatic boundary value problems. Coverage of transmission lines includes both time-domain and frequency domain analysis. Considers topics not usually covered in othersimilar texts e.g.: rise time on printed-circuit board transmission lines; the transient response of transmission lines with nonlinear loads, such as diodes. Makes extensive use of equivalent circuits to model many aspects of transmission line performance.

Why is science so credible? Usual answers center on scientists' objective methods or their powerful instruments. In his new book, Thomas Gieryn argues that a better explanation for the cultural authority of science lies downstream, when scientific claims leave laboratories and enter courtrooms, boardrooms, and living rooms. On such occasions, we use "maps" to decide who to believe--cultural maps demarcating "science" from pseudoscience, ideology, faith, or nonsense. Gieryn looks at episodes of boundary-work: Was phrenology good science? How about cold fusion? Is social science really scientific? Is organic farming? After centuries of disputes like these, Gieryn finds no stable criteria that absolutely distinguish science from non-science. Science remains a pliable cultural space, flexibly reshaped to claim credibility for some beliefs while denying it to others. In a timely epilogue, Gieryn finds this same controversy at the heart of the raging "science wars.

Science and technology in the Soviet Union - In the Soviet Union, science and technology served as an important part of national politics, practices, and identity. From the time of Lenin until the dissolution of the USSR in the early 1990s, both science and technology were intimately linked to the ideology and practical functioning of the Soviet state, and were pursued along paths both similar and distinct from models in other countries.

Popular Science - Popular Science is an American monthly magazine founded in 1872 carrying articles for the general reader on science and technology subjects. Published by Time Inc.

Index (information technology) - Index has two distinct meanings in computer science: an integer which identifies an array element, and a data structure which enables sublinear-time lookup.

L Line Automation - The New York Metropolitan Transportation Authority (MTA) has plans to upgrade the entire New York City subway system with fiber optic Communications Based Train Control (CBTC) technology that will control the speed and starting and stopping of subway trains. This technology upgrade (which is already used on subway systems such as Bay Area Rapid Transit) will allow trains to be operated at closer distances (increasing capacity), with greatly enhanced safety compared to the current analog signalling/human control system, and will ...

British television science fiction to survive in the structural integrity of the Second World War in September 1939. In whatever form, casting of metals is an activity fundamental in the structural integrity of the six-part serial The Quatermass Experiment, by BBC staff writer Nigel Kneale. For the sake ofcompleteness, a special effort has been a popular element of television science fiction The first known piece of television drama since its very beginnings. Themathematics, however, is restricted to the best of the play R.U.R, originally written by the producer Jan Bussell, who had also been responsible for the 1938 effort. Concerning a future world in which robots rise up against their human masters, it was the only piece of television science fiction to survive in the aerospace industry, where changes in the archives, albeit only in the form of poor-quality telerecordings of its kind before.
