Verbal noun of → multiply.
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.
Involving → multiplication.
Fr.: identité multiplicative
The number which when used as the multiplier of another number leaves the second unchanged; one.
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.
1) The state of being multiple, made of several components.

Agent noun of → multiply.
To make many or manifold; increase the number, quantity, etc., of.

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."

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.
From M.Fr. muraille, from L. muralia, neut. pl. of muralis "of a wall," from murus "wall;" → instrument.
Sâzâl, → instrument; 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. Skt. dehī- "wall;" Gk. teikhos "wall;" E. dike, ditch.
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.
