Fr.: ordinateur analogique
A computer in which data is stored and processed in the form of continually varying signals representing a physical quantity rather than in the form of individual numerical values. The simplest analogue computers are side rules, thermometers, voltmeters, and speedometers.
1) A similarity or comparability between two things.
1) General: The separation of an intellectual or material whole into its
constituent parts for individual study. The study of such constituent
parts and their interrelationships in making up a whole
(opposite of → synthesis).
From M.L. analysis, from Gk. analysis "a breaking up," from analyein "unloose," from ana- "up, throughout" + lysis "a loosening," from lyein "to loosen, release, untie". The L. cognate and counterpart of this Gk. word, i.e. luere has formed the words solve, dissolve, solution. The Skt. cognate lu, lunoti "to cut, sever, mow, pluck, tear asunder, destroy," lava "cutting, plucking; what is cut; fragment, piece;" PIE *leu- "to loosen, divide, cut apart". The Eng. lose, loose and Ger. los derive from this root.
Ânâlas, from ânâ-, → ana-, +
las "loose" ([Mo'in], Gilaki, Tabari, Tâleši, Aftari). We do not
know the Av./O.Pers. counterparts of these Gk. las, lysis, lyein,
believe that las and the following words probably derive from
the above-mentioned PIE *leu-:
Of or relating to analysis, in contrast with → synthetic. Also analytical.
Pertaining to ânâlas, → analysis.
Fr.: courbe analytique
A curve whose parametric equations are real → analytic functions of a single real variable.
Fr.: fonction analytique
A function which can be represented by a convergent → power series.
Fr.: géométrie analytique
The study of the geometry of figures by algebraic representation and manipulation of equations describing their positions, configurations, and separations.
Fr.: langue analytique
A language that is characterized largely by the fact that it depends on word order, rather than on inflections (grammatical endings), to convey sentence meanings. In an analytic language relations between nouns and adjectives are expressed using prepositions. English and (to a lesser extent) French, and Persian are considered analytic languages, while German and Russian are → synthetic languages.
Same as → analytic.
Fr.: mécanique analytique
A branch of → mechanics based on → variational principle that describes systems by their → Lagrangian or → Hamiltonian. Analytical mechanics provides a formalism that is different from that of Newton and does not use the concept of force. Among other things, analytical mechanics gives a more simple description of continuous and constrained systems. Moreover, its mathematical structure allows it an easier transition to quantum mechanical topics.
Infinitive of → analysis.
The quality of an → anamorphic system.
râžmân-e ânârixt, ~ ânârixtmand
Fr.: système anamorphique
An optical system whose optical power, and imaging scale, differs in the two principal directions. See also → anamorphosis.
1) Optics: The formation of a distorted image by an
→ anamorphic system.
From Gk. anamorphosis "transformation," noun of action from anamorphoein "to transform," from → ana- "up," + morphe "form" + -sis a suffix forming abstract nouns of action, process, state, condition, etc.
Ananke [Jupiter XII]
The thirteenth of Jupiter's known satellites discovered by S.B. Nicholson in 1951. It orbits the planet at a mean distance of 21,200,000 km, and has a diameter of about 30 km.
In Gk. mythology, Ananke is the personification of destiny, unalterable necessity and fate; she is also the mother of Adrastea,
A lens designed to correct → astigmatism.
1) (Conjunction, used to connect grammatically coordinate words, phrases, or clauses)
Along or together with; as well as; in addition to; besides; also; moreover.
→ if and only if.
From M.E., from O.E., akin to O.H.G. unti "and."
Va "and," graphical corruption of o "and;" Mid.Pers. ut, u- "and;" O.Pers. utā; Av. uta- "and;" cf. Skt. utá; maybe also influenced by Av. vā a disjunctive particle (Skt. vā) "or," occasionally used in the sense of "and;" vā ... vā "either, or;" cf. Sogd. βa, fa "and, or," fā "or."
Fr.: pont d'Anderson
A. Anderson (1891, Phil. Mag. (5) 31, 329); → bridge.
Ândromedâ, Zan-e bé Zanjir Basté (#)
In Gk. mythology, Andromeda was the princess of Ethiopia, daughter of → Cepheus and → Cassiopeia. The queen Cassiopeia angered Poseidon by saying that Andromeda (or possibly Cassiopeia herself) was more beautiful than the Nereids. Poseidon sent a sea monster to prey upon the country; he could be appeased only by the sacrifice of the king's daughter. Andromeda in sacrifice was chained to a rock by the sea; but she was rescued by → Perseus, who killed the monster and later married her. Cassiopeia, Cepheus, and Andromeda were all set among the stars as constellations.
Zan-e bé Zanjir Basté "the chained woman," coined by the 11th century astronomer Biruni, from Ar. Emra'at al-mosalsalah "the chained woman," from the Gk. mythology.
