general harvin Fr.: général (Adj.) 1) Not limited to one class, field, product, service, etc.
2) Relating to the whole or to the all or most.
3) Dealing with overall characteristics, universal aspects, or important elements. From L. generalis "relating to all, of a whole class," from genus "race, stock, kind," akin to Pers. zâdan, Av. zan- "to bear, give birth to a child, be born," infinitive zazāite, zāta- "born;" Mod.Pers. zâdan, present stem zā- "to bring forth, give birth" (Mid.Pers. zâtan; cf. Skt. jan- "to produce, create; to be born," janati "begets, bears;" Gk. gignomai "to happen, become, be born;" L. gignere "to beget;" PIE base *gen- "to give birth, beget." Harvin, from Mid.Pers. harvin "all," from har(v) "all, each, every" (Mod.Pers. har "every, all, each, any"); O.Pers. haruva- "whole, all together;" Av. hauruua- "whole, at all, undamaged;" cf. Skt. sárva- "whole, all, every, undivided;" Gk. holos "whole, complete;" L. salvus "whole, safe, healthy," sollus "whole, entire, unbroken;" PIE base *sol- "whole." |

general relativistic bâzânigimand-e harvin Fr.: de relativité générale Of, relating to, or subject to the theory of → general relativity. → general; → relativistic. |
general relativity bâzânigi-ye harvin Fr.: relativité générale The theory of → gravitation developed by Albert Einstein (1916) that describes the gravitation as the → space-time curvature caused by the presence of matter or energy. Mass creates a → gravitational field which distorts the space and changes the flow of time. In other words, mass causes a deviation of the → metric of space-time continuum from that of the "flat" space-time structure described by the → Euclidean geometry and treated in → special relativity. General relativity developed from the → principle of equivalence between gravitational and inertial forces. According to general relativity, photons follow a curved path in a gravitational field. This prediction was confirmed by the measurements of star positions near the solar limb during the total eclipse of 1919. The same effect is seen in the delay of radio signals coming from distant space probes when grazing the Sun's surface. Moreover, the space curvature caused by the Sun makes the → perihelion of Mercury's orbit advance by 43'' per century more than that predicted by Newton's theory of gravitation. The → perihelion advance can reach several degrees per year for → binary pulsar orbits. Another effect predicted by general relativity is the → gravitational reddening. This effect is verified in the → redshift of spectral lines in the solar spectrum and, even more obviously, in → white dwarfs. Other predictions of the theory include → gravitational lensing, → gravitational waves, and the invariance of Newton's → gravitational constant. → general; → relativity. |

generalized coordinates hamârâhâ-ye harvinidé Fr.: coordonnées généralisées In a material system, the independent parameters which completely specify the configuration of the system, i.e. the position of its particles with respect to the frame of reference. Usually each coordinate is designated by the letter q with a numerical subscript. A set of generalized coordinates would be written as q_{1}, q_{2}, ..., q_{n}. Thus a particle moving in a plane may be described by two coordinates q_{1}, q_{2}, which may in special cases be the → Cartesian coordinates x, y, or the → polar coordinates r, θ, or any other suitable pair of coordinates. A particle moving in a space is located by three coordinates, which may be Cartesian coordinates x, y, z, or → spherical coordinates r, θ, φ, or in general q_{1}, q_{2}, q_{3}. The generalized coordinates are normally a "minimal set" of coordinates. For example, in Cartesian coordinates the simple pendulum requires two coordinates (x and y), but in polar coordinates only one coordinate (θ) is required. So θ is the appropriate generalized coordinate for the pendulum problem. → generalized; → coordinate. |
generalized forces niruhâ-ye harvinidé Fr.: forces généralisées In → Lagrangian dynamics, forces related to → generalized coordinates. For any system with n generalized coordinates q_{i} (i = 1, ..., n), generalized forces are expressed by F_{i} = ∂L/∂q_{i}, where L is the → Lagrangian function. → generalized; → force. |
generalized momenta jonbâkhâ-ye harvinidé Fr.: quantité de mouvement généralisée In → Lagrangian dynamics, momenta related to → generalized coordinates. For any system with n generalized coordinates q_{i} (i = 1, ..., n), generalized momenta are expressed by p_{i} = ∂L/∂q^{.}_{i}, where L is the → Lagrangian function. → generalized; → momentum. |
generalized velocities tondâhâ-ye harvinidé Fr.: vitesses généralisées The time → derivatives of the → generalized coordinates of a system. → generalized; → velocity. |
New General Catalogue (NGC) kâtâlog-e harvin-e now Fr.: New General Catalogue A catalogue of 7,840 non-stellar objects compiled by J. L. E. Dreyer and published in 1888. A further 1,529 objects were listed in a supplement that appeared seven years later, called the → Index Catalogue (IC). The Second Index Catalogue of 1908 extended the supplementary list to 5,386 objects. |
