91Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… …
92Pockels effect — The Pockels effect, or Pockels electro optic effect, produces birefringence in an optical medium induced by a constant or varying electric field. It is distinguished from the Kerr effect by the fact that the birefringence is proportional to the… …
93Metamaterial — Negative index metamaterial array configuration, which was constructed of copper split ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3 by 20×20 unit cells with overall dimensions …
94international relations — a branch of political science dealing with the relations between nations. [1970 75] * * * Study of the relations of states with each other and with international organizations and certain subnational entities (e.g., bureaucracies and political… …
95EPR paradox — In quantum mechanics, the EPR paradox is a thought experiment which challenged long held ideas about the relation between the observed values of physical quantities and the values that can be accounted for by a physical theory. EPR stands for… …
96Nonholonomic system — A nonholonomic system in physics and mathematics is a system whose state depends on the path taken to achieve it. Such a system is described by a set of parameters subject to differential constraints, such that when the system evolves along a… …
97Optical fiber — A bundle of optical fibers A TOSLINK fiber optic audio c …
98mechanoreception — See mechanoreceptor. * * * Ability to detect and respond to mechanical stimuli in one s environment. A slight deformation of a mechanoreceptive neuron causes an electric charge at its surface, activating a response. Mechanoreceptors in pain spots …
99Defining equation (physics) — For common nomenclature of base quantities used in this article, see Physical quantity. For 4 vector modifications used in relativity, see Four vector. Very often defining equations are in the form of a constitutive equation, since parameters of… …
100Ellipsometry — is a versatile and powerful optical technique for the investigation of the dielectric properties (complex refractive index or dielectric function) of thin films. It has applications in many different fields, from semiconductor physics to… …
