  • optical computing — (hardware)   (Or "Optical Signal Processing") Operating on data represented using electromagnetic radiation, e.g. visible light, instead of the electrical signals used in a conventional electronic digital computer. Electronic digital computers are built from transistors. These form components that store data and logic gates that perform the low-level Boolean operations such as AND, OR and NOT that are the basis of all digital computation. The optical equivalent requires material with a non-linear refractive index such that light beams can interact with each other to perform the same Boolean operations. Though the photons that carry optical signals offer some theoretical advantages over the electrons that carry electronic signals, there are many practical problems that would have to be overcome before optical computing could compete in terms of cost, power and speed.
  • out of commission — the act of committing or entrusting a person, group, etc., with supervisory power or authority.
  • out of one's mind — (in a human or other conscious being) the element, part, substance, or process that reasons, thinks, feels, wills, perceives, judges, etc.: the processes of the human mind.
  • outline agreement — a contract, etc, setting out the preliminary terms or guidelines for an agreement; a preliminary agreement
  • per procurationem — by one acting as an agent; by proxy.
  • permutation group — a mathematical group whose elements are permutations and in which the product of two permutations is the same permutation as is obtained by performing them in succession.
  • pernicious anemia — Pernicious anemia is a very severe blood disease.
  • photoluminescence — luminescence induced by the absorption of infrared radiation, visible light, or ultraviolet radiation.
  • phumiphon aduldet — (Phumiphon Aduldet; Bhumibol Adulyadej) born 1927, king of Thailand since 1946.
  • physical pendulum — any apparatus consisting of a body of possibly irregular shape allowed to rotate freely about a horizontal axis on which it is pivoted (distinguished from simple pendulum).
  • picture messaging — Picture messaging is the sending of photographs or pictures from one mobile phone to another.

  • potassium cyanide — a white, granular, water-soluble, poisonous powder, KCN, having a faint almondlike odor, used chiefly in metallurgy and photography.

  • production number — a specialty number or routine, usually performed by the entire cast consisting of musicians, singers, dancers, stars, etc., of a musical comedy, vaudeville show, or the like.
  • production system — (programming)   A production system consists of a collection of productions (rules), a working memory of facts and an algorithm, known as forward chaining, for producing new facts from old. A rule becomes eligible to "fire" when its conditions match some set of elements currently in working memory. A conflict resolution strategy determines which of several eligible rules (the conflict set) fires next. A condition is a list of symbols which represent constants, which must be matched exactly; variables which bind to the thing they match and "<> symbol" which matches a field not equal to symbol. Example production systems are OPS5, CLIPS, flex.
  • programming fluid — (jargon)   (Or "wirewater") Coffee, unleaded coffee (decaffeinated), Cola, or any caffeinacious stimulant. Many hackers consider these essential for those all-night hacking runs.
  • pseudo-humanistic — a person having a strong interest in or concern for human welfare, values, and dignity.
  • purely and simply — You use purely and simply to emphasize that the thing you are mentioning is the only thing involved.
  • quantum cell wire — (electronics, computing)   (Or "quantum wire", "binary wire") Quantum cells arranged in a line to carry signals. Adjacent cells with the same orientation are at a low energy state and a change of orientation at one end of a quantum wire propagates along the wire, transmitting a signal. However, unlike conventional wire, since only the orientation of charge pairs changes, no current flows. Circuits created using quantum cell wires are referred to as Quantum-dot Wireless Digital Circuits, see quantum dot, Quantum-dot Cellular Automata.
  • quantum chemistry — the application of quantum mechanics to the study of chemical phenomena.
  • quantum computing — quantum computer
  • quantum mechanics — a theory of the mechanics of atoms, molecules, and other physical systems that are subject to the uncertainty principle. Abbreviation: QM.
  • quasiexperimental — (medicine) Describing a trial in which the assignment to a group is based upon an experimental condition.
  • radioluminescence — luminescence induced by nuclear radiation.
  • reconstructionism — a 20th-century movement among U.S. Jews, founded by Rabbi Mordecai M.

  • recurring decimal — Mathematics. repeating decimal.
  • recursion formula — a formula for determining the next term of a sequence from one or more of the preceding terms.
  • recursive acronym — (convention)   A hackish (and especially MIT) tradition is to choose acronyms and abbreviations that refer humorously to themselves or to other acronyms or abbreviations. The classic examples were two MIT editors called EINE ("EINE Is Not Emacs") and ZWEI ("ZWEI Was EINE Initially"). More recently, there is a Scheme compiler called LIAR (Liar Imitates Apply Recursively), and GNU stands for "GNU's Not Unix!" - and a company with the name CYGNUS, which expands to "Cygnus, Your GNU Support". See also mung.
  • reduction formula — a formula, such as sin (90° ± A) = cos A, expressing the values of a trigonometric function of any angle greater than 90° in terms of a function of an acute angle
