multiple star setâre-ye bastâyi Fr.: étoile multiple A star which appears single but is in fact composed of more than two components. See also → multiple star system; → binary star; → triple star. |
multiple star system râšmân-e bastâyi Fr.: système multiple A stellar system composed of several stars bound together by gravitational attraction and revolving around a common center of mass. |
multiple system râžmân-e bastâyi Fr.: système multiple 1) A system consisting of several → components. |
multiplet bastâyé Fr.: multiplet A group of spectral lines arising from transitions having a common lower energy level. From → multi- + -plet on the model of triplet. Bastâyé, from bastâ-→ multi- + euphonic -yé, from -é nuance suffix. |
multiplicand bastâšow Fr.: multiplicande A number to be multiplied by another. From L. multiplicandum, from multiplicandus "to be multiplied," gerundive of multiplicare, → multiply. Bastâšow, literally "that undergoes multiplication," from bastâ, → multiple, + šow, present stem and agent noun of šodan "to become, to be, to be doing, to go, to pass," from Mid.Pers. šudan, šaw- "to go;" Av. šiyav-, š(ii)auu- "to move, go," šiyavati "goes," šyaoθna- "activity; action; doing, working;" O.Pers. šiyav- "to go forth, set," ašiyavam "I set forth;" cf. Skt. cyu- "to move to and fro, shake about; to stir," cyávate "stirs himself, goes;" Gk. kinein "to move;" Goth. haitan "call, be called;" O.E. hatan "command, call;" PIE base *kei- "to move to and fro." |
multiplication bastâyeš Fr.: multiplication In general, the process of repeatedly adding a quantity to itself a certain number of times, or any other process which has the same result. Verbal noun of → multiply. |
multiplication sign nešâne-ye bastâyeš Fr.: croix de multiplication The sign used to indicate multiplication, either a times sign (×), a centered dot (·), or an asterisk. The multiplication sign was introduced by William Oughtred in 1631. → multiplication; → sign. |
multiplicative bastâyeši Fr.: multiplicatif Involving → multiplication. |
multiplicative identity idâni-ye bastâyeši Fr.: identité multiplicative The number which when used as the multiplier of another number leaves the second unchanged; one. → multiplicative; → identity. |
multiplicative inverse vârun-e bastâyeši Fr.: inverse multiplicative The number which when used as a multiplier of another number (except 0) produces 1. For example (1/5) x 5 = 1; each of the numbers is the multiplicative inverse of the other. → multiplicative; → inverse. |
multiplicity bastâyigi Fr.: multiplicité 1) The state of being multiple, made of several components. |
multiplier bastâgar Fr.: multiplicateur Arithmetic: A number by which another is multiplied. Physics: A device for intensifying some effect. Agent noun of → multiply. |
multiply bastâyidan Fr.: multiplier To make many or manifold; increase the number, quantity, etc., of. O.Fr. multiplier, from L. multiplicare "to increase," from multiplex (gen. multiplicis) "having many folds, many times as great in number," from multi- "many" + base of plicare "to lay, fold, twist." Bastâyidan, from bastâ, → multiple, + -idan infinitive suffix. |
multipole basqotbé Fr.: multipôle An entity consisting of several poles. |
multipole index dišan-e basqotbé Fr.: indice multipolaire A variable used in → spherical harmonic expansions. Each spherical harmonic is characterized by its multipole index l: l = 0 for a → monopole, l = 1 for a → dipole, and so on. It is used in particular to describe the → cosmic microwave background anisotropy: ΔT/T_{0} (θ,φ) = Σ a_{lm}Y_{lm}(θ,φ), where θ and φ are the → spherical polar coordinates, Y_{lm} is the → spherical harmonic functions, and the sum runs over l = 1, 2, ..., ∞ and m = -l, ..., l, where the multipole index l corresponds to angular scales ≅ 180°/l. |
multipole moment gaštâvar-e basqotbé Fr.: moment multipolaire The quantity that gives the electric potential field due to a distribution of charges, such as a → dipole, → quadrupole, → octupole, etc. A multipole moment usually involves powers of the distance to the origin, as well as some angular dependence. |
multitude basiné Fr.: multitude 1) A great number. M.E., from O.Fr. multitude and directly from L. multitudo "a great number, a crowd; the common people," from multus "many, much," → multi-, + suffix -tudo "-tude." Basiné, from basin + superlative of bas "many, much," → multi-, + suffix -in + -é noun/nuance suffix (as bišiné, kaminé, etc.). |
multivariate basvartâ Fr.: multivarié Statistics: Having more than one → variable. |
multivariate time series seri-ye zamâni-ye basvartâ Fr.: série temporelle multivariée A → time series consisting of two or more → univariate time series which share the same time period. As an example, if we record wind velocity and wind direction at the same instant of time, we have a multi-variate time series, specifically a bivariate one. → multivariate; → time; → series. |
multiverse gitigân Fr.: multivers A → hypothetical set of → multiple universes, including our → Universe, that together comprise all of physical reality. Initially coined by William James (1895) "an alternative to universe meant to convey absence of order and unity." In modern cosmology coined from -verse in → universe, by replacing uni- with multi- to denote "multiple universes." Gitigân, from giti, → universe, + -gân multiplicity suffix. |
