conformal compactification hampakâneš-e hamdi Fr.: compactification conforme A mapping of an infinite → space-time onto a finite one that may make the far away parts of the former accessible to study. The technique invented by Penrose defines an equivalence class of → metrics, g_{ab} being equivalent to ĝ_{ab} = Ω^{2}g_{ab}, where Ω is a positive scalar function of the space-time that modifies the distance scale making the asymptotics of the physical metric accessible to study. → conformal; → compactification. |
conformal mapping hamtâyeš-e hamdis Fr.: application conforme A continuous mapping u = f(x) of a domain D in an n-dimensional Euclidean space (n≥ 2) into the n-dimensional Euclidean space is called conformal at a point x_{0}∈ D if it has the properties of constancy of dilation and preservation of angles at this point. |
confound pašidan Fr.: confondre 1) To throw into confusion or disorder. M.E. conf(o)unden, from Anglo-Fr. confoundre, O.Fr. confondre "throw into disorder, crush, ruin," from L. confundere "to confuse," literally "to pour together, mix, mingle," from → com- + fundere "to pour" Pašidan, from Tâti paši "confused, blend;" ultimately from Proto-Ir. *apa-šan-, from *šan- "to shake;" cf. Mid.Pers. pašân-, afšân- "to spread, scatter;" Pers. afšândan "to disperse;" Kurd. pašiv "messy, disordered," pašukân "to be agitated, distraught;" Gilaki voršin "messy, disordered;" see → chaos for other dialectal examples. |
confuse pašidan Fr.: confondre 1) To make unclear or indistinct. Back formation from confused, M.E. confused, from O.fr. confus, from L. confusus, p.p. of confundere, → confound. → confound. |
confused pašidé, pašnâk Fr.: confus 1) (Of a person) Unable to think clearly; perplexed. Past participle of → confuse. |
confusion pašeš Fr.: confusion 1) The act of confusing. Verbal noun of → confuse. |
confusion limit hadd-e pašeš Fr.: limite de confusion The → fluctuations of the → background → sky brightness below which astronomical → sources cannot be → detected individually. The confusion limit is reached when the density of sources brighter than the → root mean square → noise becomes high enough within the area of the resolution element. |
conglomerate hâgolemidan Fr.: conglomérer 1) Anything composed of heterogeneous materials or elements. From L. conglomeratus, p.p. of conglomerare "to roll together," from → com- "together" + glomerare "to gather into a ball," from glomus (genitive glomeris) "a ball," globus "globe;" PIE *gel- "to make into a ball." Hâgolemidan, from hâ- "together," → com-, + golem "glomus," → agglomerate. |
conglomeration hâgolemeš Fr.: conglomération 1) The act of conglomerating; the state of being conglomerated. Verbal noun of → conglomerate. |
congruence damsâzi Fr.: congruence The quality or state of agreeing or corresponding. → congruent. Noun form of → congruent. |
congruent damsâz Fr.: congruent 1) Agreeing; accordant. Congruent "suitable, proper," from L. congruentem (nominative congruens) "agreeing, fit, suitable," p.p. of congruere, literally "to come together, agree, correspond with," from → com- "with" + a lost verb *gruere, *ruere "fall, rush." Damsâz "agreeing, consenting, harmonious," maybe from hamsâz "unanimous," → compatible. |
congruent angles zâviyehâ-ye damsâz Fr.: angles congrus Two angles if they have the same measure. Congruent angles may lie in different orientations or positions. |
congruent circles parhunhâ-ye damsâz Fr.: cercles congrus Two circles if they have the same size. |
congruent line segments borankhâ-ye damsâz Fr.: segments congru Two line segments if they have the same length. They need not lie at the same angle or position on the plane. |
congruent number adad-e damsâz Fr.: nombre congru Number theory: An → integerN if there exists a → right triangle with → rational sides so that the area of the triangle is N. For example, the number N = 6, because of the 3-4-5 triangle. |
congruent polygons candbarhâ-ye damsâz Fr.: polygones congrus Polygons that have an equal number of sides, and all the corresponding sides and angles are congruent. However, they can be in a different location, rotated or flipped over. |
congruent triangles sebarhâ-ye damsâz Fr.: triangles congrus Two triangles when all corresponding sides and interior angles have the same measure. The triangles will have the same shape and size, but one may be a mirror image of the other. |
conic maxruti (#) Fr.: conique Same as → conic section. Adj. from → cone. |
conic section sekanj-e maxruti Fr.: section conique A curve which may be represented as the intersection of a plane with a cone; hence a → parabola, → hyperbola, or → ellipse. |
conjecture hâšan Fr.: conjecture An opinion or theory formed without sufficient evidence for proof; guess; speculation. M.E., from O.Fr. conjecture "surmise, guess," or directly from L. coniectura "conclusion, interpretation, guess, inference," literally "a casting together (of facts, etc.)," from coniectus, p.p. of conicere "to throw together," from → com- "together" + iacere "to throw," → eject. Hâšan, from hâ-, variant ham-, → com-, + šan, from ešândan "to throw out," → eject. |
