To put off to a later time; defer.
1) farâvas; 2) farâvasidan
Fr.: 1) postulat; 2) postuler
1a) Math.: An unproved → assumption
taken as basic in a mathematical
system, and from which (in combination with other → postulates)
of the system are derived, or in terms of which the propositions are proved.
In modern usage, postulate is synonymous with → axiom.
From L. postulatum "petition, thing requested," noun use of neuter of p.p. of postulare "to ask, request, demand," akin to poscere "to request."
Farâvas (on the model of piš-nahâd "proposition,"
and farâ-nemudan "to exhibit, expose"), from farâ-,
→ pro-, + vas. The second component from
Av. vas- "to will, desire, wish, long for," vasəmi
"I wish," vasna- "will, favor," ušti- "desire, wish, will,"
vasô, vasə "at one's will;" cf. O.Pers. vasiy
"at will, greatly, utterly," vašna- "will, favor;"
Mid.Pers. vasnâd "because, on account of."
This word is extant in several Modern Iranian
dialects: Tabari vessen "to wish, desire," Gilaki vâssan
"to wish, desire," vâsti "desire; for, because, on account of;"
Kurd. wistin "to desire, wish," Lâri avessa "to desire;"
Nâyini vas "to like;" colloquial
Tehrâni vâsé "for;"
Lori, Malâyeri biza "pregnancy craving;"
cognate with Skt. vaś- "to wish, want, desire," váśa-
"wish, desire," vasēna "for, because;" Gk. ekon "voluntary;"
PIE base *uek- "to wish."
A silvery-white metallic chemical element; symbol K (from L. kalium "potash"). Atomic number 19; atomic weight 39.0983; melting point 63.25°C; boiling point 760°C.
Coined by the English chemist Sir Humphrey Davy (1778-1829), who first isolated it in 1807 from electrolysis of caustic potash (KOH); from Mod.L. potassa, Latinized form of E. potash + -ium.
1) A latent ability that may or may not be developed; possibility.
From L.L. potentialis "potential," from L. potentia "power," potis "powerful, able, capable;" cognate with Av. paiti- "lord, husband;" Mod.Pers. -bad (sepah-bad "general, commander of an army"); Skt. páti- "master, husband;" Gk. posis "husband;" Lith. patis "husband."
Tavand, from tav- + -vand. The first component tav-
is the stem of tavân "power, strength," tavânestan "to be powerful,
able;" variants tâv, tâb, (dialects) tew "power;" Mid.Pers. tuwan
"power, might;" O.Pers. tav- "to have power, to be strong, to be able,"
tauman- "power, strength," tunuvant- "powerful;"
Av. tauu- (tu-) "to be able, strong,"
tavah- "power," təviši- "strength" (Mod.Pers.
tuš "power, ability");
Skt. tavi- "to be strong, to have authority,"
tavas-, tavisa- "strong, energetic," tavisi- "power, strength;"
Gk. taus, saos "healthy;" L. tumere "to be swollen;" PIE
*teu- "to swell, be strong." The second component -vand
a suffix of adjectives and agent nouns, → actual.
Fr.: barrière de potentiel
Region in a field of force in which the potential is such that a particle, which is subject to the field, encounters opposition to its passage.
Fr.: densité potentielle
Of a fluid parcel at pressure P, the density that it would acquire if adiabatically brought to a reference pressure.
Fr.: différence de potentiel
Between two points, the work done in taking the unit test object from one point to the other. Potential is a scalar quantity.
Fr.: énergie potentielle
Of a system, the work done in changing the system from some standard configuration to its present state. Thus, if a body of mass m is raised vertically through a height h, the work done, mgh, is the increase in potential energy.
potential energy curve
xam-e kâruž-e tavand
Fr.: courbe de l'energie potentielle
A plot that displays the → potential energy of a moving body as a function of its position. It is explained by the → conservation of energy and the conversion of potential energy into → kinetic energy and vice versa.
Fr.: champ de potentiel
A field that has a → potential. A continuous → vector fieldA in a domain D is a potential field in D if and only if its → work around every closed curve C contained in D is zero: ∫A.ds = 0. Examples include the → gravitational field and the → electrostatic field.
Fr.: gradient de potentiel
At a point, the rate of change of potential V, with distance x, measured in the direction in which the variation is a maximum. The intensity F of the field is proportional to the potential gradient, but is oppositely directed: F = -dV/dx.
Fr.: puit de potentiel
Region in a → field of force in which the potential decreases abruptly, and in the surrounding region of which the potential is larger.
With a possibility of becoming actual; possibly.
potentially hazardous asteroid (PHA)
seyyârak-e tavandâné âpenâk
Fr.: astéroïde potentiellement dangereux
An asteroid that could make a threatening close approach to the Earth. In technical terms a PHA is defined as having an → absolute magnitude of 22 or brighter and an → Earth Minimum Orbit Intersection Distance (MOID) of less than 0.05 → astronomical unit or 7.5 million km.
An instrument for measuring electrical quantities by balancing an unknown potential difference against a known potential difference.
Fr.: puissance, pouvoir
1) Physics: The → rate of doing
→ work on transferring → energy, as
expressed in ergs/sec, watts, etc. Same as → mechanical power.
M.E. pouer(e), poer(e), from O.Fr. povoir, noun use of the infinitive in O.Fr., "to be able," from V.L. *potere, from L. potis "powerful, able, capable;" cognate with Av. paiti- "lord, husband;" Mod.Pers. -bad (sepah-bad "general, commander of an army"); Skt. pái- "master, husband;" Gk. posis "husband;" Lith. patis "husband."
Tavân "power, strength," tavânestan "to be powerful, able;" Mid.Pers. tuwan "power, might," from O.Pers./Av. base tav- "to have power, to be strong, to be able," Av. tavah- "power," təviši- "strength," Mod.Pers. tuš, tâb "power, ability," O.Pers. tauman- "power, strength," tunuvant- "powerful," Skt. tu- "to be strong, to have authority," tavas-, tavisa- "strong, energetic," tavisi- "power, strength."
Fr.: fonction de puissance
A function of the form f(x) = xn, where n is a → real number.
qânun-e tavâni (#)
Fr.: loi de puissance
A mathematical relationship between two quantities expressed by a → power function.
seri-ye tavâni (#)
Fr.: série de puissance
A series in which the terms contain regularly increasing powers of a variable. In general, a0 + a1x + a2x2 + ... + anxn, where a0, a1, etc. are constants.
