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/T0 (θ,φ) = Σ almYlm(θ,φ), where θ and φ are the → spherical polar coordinates, Ylm 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.
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.
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 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.
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."

multiwire proportional chamber
otâqak-e besyâr-sim-e barpâreši
Fr.: chambre proportionnelle multifils
Same as → Charpak's detector.
A short-lived → elementary particle with negative → electric charge, represented by the symbol μ-. The muon was discovered in 1936 by Carl Anderson (1905-1991) in → cosmic rays. It shares several properties with the electron: it is a → lepton with the same charge and → spin as the electron. But it is heavier than the electron (105 MeV/c2), about 200 times more massive. The muon is instable and decays after 2.197 × 10-6 s into → electron, → neutrino, and → antineutrino (μ-→ e- + νμ + anti νe) .
A shortening of mu meson, from mu the 12th letter of the Gk. alphabet, + → meson.
Fr.: télescope muonique
An → instrument used in → geophysics to determine the average → density of geological bodies by measuring the → attenuation produced by → rocks on the flux of → atmospheric muons. This density muon → radiography is or example used to study the physical conditions inside → volcanoes.
Of, relating to, or resembling a wall.
From M.Fr. muraille, from L. muralia, neut. pl. o f muralis "of a wall," from murus "wall."
Divâri "of a wall," from divâr "wall," from Mid.Pers. dîvâr "wall;" related to Mid.Pers. bâr, var "enclosure, defences, fortress;" Mod.Pers. bâru "wall, rampart, fortification; fort; tower;" O.Pers. didā- "wall, stronghold, fortress;" Av. var- "castle," from var- "to cover, conceil;" Proto-Iranian *dida-vāra-; cf.

Fr.: instrument mural
An angle measuring device mounted on or built into a wall. For astronomical purposes, these walls were oriented so they lie precisely on a meridian.
cârakân-e divâri (#)
Fr.: quadrant mural
A → mural instrument used to determine stellar positions. The quadrant consisted of a wall supporting a 90° graduated arc carefully oriented to the meridian. By means of a movable arm equipped with a sight, the altitude of a star could be determined at meridian passage.
