  • Alexa Internet [r]: A subsidiary of Amazon.com that provides traffic data, global rankings and other information on 30 million websites world wide. [e]
  • Analytic-synthetic distinction [r]: A distinction used in philosophy to divide an ontology into two parts: an analytic part consisting of terms related by synonymy, and a synthetic part concerning connections between such terms and 'real' objects. [e]
  • Answers.com [r]: A web-based question-and-answers site that copies information from other web sites. [e]
  • Ask.com [r]: A question-answering web search engine owned and operated by Dublin, Ireland-based IAC Search & Media Europe, Ltd. [e]
  • Asymptotic gain model [r]: A formal expression for the gain of negative feedback amplifiers that can provide intuitive insight and often is easier to evaluate than a direct analysis of the gain. [e]
  • Atomic units [r]: A system of units convenient for atomic and molecular calculations. [e]
  • Biological computation [r]: The study of computational processes in biological systems [e]
  • Bipolar transistor [r]: A three-terminal semiconductor device used for switching and amplification. [e]
  • Bode plot [r]: A graph of the complex logarithm of the transfer function of a linear, time-invariant system plotted with a log-frequency axis. There are two plots: the Bode magnitude plot and the Bode phase plot, governing the real and the imaginary parts of the transfer function. [e]
  • Boolean algebra [r]: A form of logical calculus with two binary operations AND (multiplication, •) and OR (addition, +) and one unary operation NOT (negation, ~) that reverses the truth value of any statement. [e]
  • Cent (music) [r]: The logarithmic division of the equitempered semitone into 100 equal parts. It is therefore the 1200th root of 2, a ratio approximately equal to (1:1.0005777895). [e]
  • Centrifugal force [r]: A radially outward force experienced by an object moving in a curved path [e]
  • Centripetal force [r]: The force directed normal to the path of a moving body that enables the body to navigate the curvature of the path [e]
  • Clairaut's theorem [r]: A theorem describing the figure of the Earth as an oblate spheroid. [e]
  • Cognitive psychology [r]: The branch of cognitive science that deals with human mental processes involved in thinking, feeling and behaving. [e]
  • Comité International des Poids et Mesures [r]: An international committee set up to promote uniformity in units of measurement. [e]
  • Coriolis effect [r]: A disorientation caused by misinterpretation of rotational signals by the ear, important particularly to astronauts and pilots. [e]
  • Coriolis force [r]: An inertial force upon a moving object that is perpendicular to its velocity as that is seen from a rotating frame of reference, and also to the axis of rotation. [e]
  • Current mirror [r]: An electrical circuit designed to control a current through one active device by copying the current in another active device, thereby keeping the output current constant regardless of loading. [e]
  • Determinism [r]: A philosophical position that our acts are the consequences of the laws of nature and therefore the consequences of our acts are not our responsibility. [e]
  • Dilemma of determinism [r]: A moral quandary posed by a belief that events are determined by outside agency, placing human decisions outside moral responsibility [e]
  • Doppler effect [r]: Frequency changes of a wave due to relative motion between source and observer. [e]
  • Electronic band structure [r]: The very closely spaced energy levels available to electrons in solids, which are separated from each other by energy gaps. [e]
  • Elementary particle [r]: A particle that has no internal structure; that is, both theoretically and experimentally there are no constituent particles that combine to make it up. [e]
  • Envelope function [r]: A smooth curve outlining the extremes in amplitude of a rapidly varying function. [e]
  • Extended cognition [r]: The extension of mental processes and mind beyond the body to include aspects of the environment in which an organism is embedded and the organism's interaction with that environment [e]
