farbin-e hastumandi, ~ hasti
Fr.: théorème d'existence
Existing; having existence.
1) Of or relating to → existence, especially
Fr.: quantificateur existentiel
A symbol of → predicate logic which expresses that the statements within its scope are → true for at least one instance of something. The symbol ∃ is used as the existential quantifier. Existential quantifiers are normally used in logic in → conjunction with → predicate symbols, which say something about a → variable or → constant, in this case the variable being quantified (→ quantify, → quantification).
A philosophical attitude associated especially with Heidegger, Jaspers, Marcel, and Sartre, and opposed to → rationalism and → empiricism, that stresses the individual's unique position as a self-determining agent responsible for the authenticity of his or her choices (Dictionary.com).
An advocate of → existentialism.
To stretch out; draw out to the full length; to enlarge the scope of; to increase the length or duration of.
From O.Fr. estendre, from L. extendere "stretch out," from → ex- "out" + tendere "to stretch," see below.
Ostanidan, from os-, → ex- + tanidan as in Av. ustāna- "stretched out" (ustāna-zasta- "with outstretched hands"), cf. Skt. uttāná- "stretched out, spread out." Mod.Pers. tanidan "to spin, twist, weave;" Mid.Pers. tanitan, from Av. tan- to stretch, extend;" cf. Skt. tan- to stretch, extend," tanoti "stretches," tantram "loom;" Gk. teinein "to stretch, pull tight;" L. tendere "to stretch;" PIE base *ten- "to stretch."
Fr.: objet étendu
An object whose angular size exceeds the resolution of the instrument used to observe it.
Fr.: source étendue
In radio astronomy, a source whose angular extent could be measured, as distinguished from a point source.
1) An act or instance of extending; the state of being extended.
Verbal noun of → extend.
The range over which a thing extends; length, area, volume, or scope.
1) To attach firmly or securely in place; fix securely to something else.
From M.E. fastenen, from O.E. fæstnian; cognate with O.Fris. festnia "to make firm, bind fast," O.Sax. fastnon, O.H.G. fastnion, O.N. fastna "to pledge, betroth."
Darizidan, from Proto-Ir. *darz- "to attach, fasten;" cf. Av. darəz- "to attach;" Mid.Pers. handarz "advice, order, command," drz- "to fasten;" Mod.Pers. andarz "advice; testament," darzan "needle," darzi "tailor," razé (with elimination of the initial phoneme) "a ring or staple used to fasten a door," padarzé "a wrapper in which clothes are folded up;" cf. Skt. drah- "to fix, make firm;" Gk. drassomai "I take hold of, grasp;" Russ. deržat' "to hold, keep" (Cheung 2007).
gravitational potential energy
kâruž-e tavand-e gerâneši
Fr.: énergie potentielle gravitationnelle
1) The energy that an object possesses because of its position in a
→ gravitational field, especially an object near the
surface of the Earth where the → gravitational acceleration
can be assumed to be constant, at about 9.8 m s-2.
Fr.: embrillancement gravitationnel
taneš-e pâyâ-ye Hubble-Lemaître
Fr.: Tension sur la constante de Hubble-Lemaître
The discrepancy between the value of the → Hubble-Lemaitre constant inferred from a ΛCDM fit (→ Lambda cold dark matter model) to the → cosmic microwave background (CMB) and local measurements. The Universe appears to be expanding much faster now than predicted even with our latest understanding of its initial conditions and contents. Based on the → Hubble Space Telescope observations, the Hubble-Lemaitre constant is very recently estimated to be 74.03 km s-1 Mpc-1. This value indicates that the Universe is expanding at a rate about 9% faster than that implied by the → Planck satellite's observations of the → early Universe, which give a value for the Hubble constant of 67.4 km s-1 Mpc-1. For discussion, see D'Arcy Kenworthy et al. (2019, ApJ 875, 145).
In a → right triangle, the side opposite to the right angle.
