  • legal dictionary — a specialized dictionary covering terms used in the various branches of the legal profession, as civil law, criminal law, and corporate law. A comprehensive legal dictionary adds to its body of standard English entries many words and phrases that have made their way into modern legal practice from law French and Latin and are rarely found in a general English monolingual dictionary. Such a specialized dictionary is useful not only for law students and for attorneys themselves, but for members of the lay public who require legal services. Legal dictionaries published in print follow the normal practice of sorting entry terms alphabetically, while electronic dictionaries, such as the online Dictionary of Law on Dictionary.com, allow direct, immediate access to a search term.

  • lorenz attractor — (mathematics)   (After Edward Lorenz, its discoverer) A region in the phase space of the solution to certain systems of (non-linear) differential equations. Under certain conditions, the motion of a particle described by such as system will neither converge to a steady state nor diverge to infinity, but will stay in a bounded but chaotically defined region. By chaotic, we mean that the particle's location, while definitely in the attractor, might as well be randomly placed there. That is, the particle appears to move randomly, and yet obeys a deeper order, since is never leaves the attractor. Lorenz modelled the location of a particle moving subject to atmospheric forces and obtained a certain system of ordinary differential equations. When he solved the system numerically, he found that his particle moved wildly and apparently randomly. After a while, though, he found that while the momentary behaviour of the particle was chaotic, the general pattern of an attractor appeared. In his case, the pattern was the butterfly shaped attractor now known as the Lorenz attractor.
