• 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]
• 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]
• Fermi function [r]: The equilibrium occupancy of an energy level in a system of independent fermions at a fixed temperature. ^[e]
• Foucault pendulum [r]: A pendulum demonstrating the Earth's rotation as it maintains its plane of motion independent of movement of its suspension attached to planet Earth. ^[e]
• Frame of reference (physics) [r]: An observational set of coordinates tied to the motion of an observer, used to describe physical events and possibly including a measurement apparatus. ^[e]
• Free will [r]: The intuition, or philosophical doctrine, that one can control one's actions or freely choose among alternatives. ^[e] Not originated by me, but greatly expanded and provided all sources.
• Gyromagnetic ratio [r]: The constant of proportionality between the magnetic moment and angular momentum of an object. ^[e]
• Hadron [r]: A composite particle made up of quarks bound together by the strong force, such as a meson, proton, or a neutron. ^[e]
• Hard problem of consciousness [r]: The problem of finding an explanation for how physical phenomena acquire subjective characteristics becoming, for example, colors and tastes ^[e]
• Hybrid-pi model [r]: A circuit model used for analyzing the small-signal behavior of transistors. ^[e]
• Idée fixe [r]: A preoccupation of mind held so firmly as to resist any attempt to modify it, a fixation ^[e]
• Inertial forces [r]: Forces introduced to enable the use of the laws of motion in accelerating frames of reference, such as rotational frames ^[e]
