From O.Fr. consequence "result," from L. consequentia, from consequentem (nom. consequens), prp. of consequi "to follow after," from &arr; com- "with" + sequi "to follow," (cf. Skt. sacate "accompanies, follows," Av. hacaiti, Gk. hepesthai "to follow"), from PIE base *sekw- "to follow".

Peyâmad, from pey "after; footstep; foot" (Mid.Pers. pay "step, after," O.Pers. nipadiy "on the track of, close after," from ni-, → ni- (PIE), + padiy, from pad- "foot", Av. paδa- "step, footstep," Skt. padá- "step, foorstep;" cf. Gk. pos, L. pes; PIE root *pod-/*ped-) + âmad "to come, arrive," shortened infinitive of âmadan, Mid.Pers. âmatan, O.Iranian *āgmatani, O.Pers., Av. gam- "to come; to go," Av. jamaiti "goes," Skt. gamati "goes," Gk. bainein "to go, walk, step," L. venire "to come," Tocharian A käm- "to come," O.H.G. queman "to come," E. come; PIE root *gwem- "to go, come."

consequent
  پیای، پی‌آی، پی‌آینده   
peyây, peyâyandé

Fr.: conséquent   

Logic: In a → conditional proposition, the → clause which follows then. See also → antecedent.

consequence.

conservation
  پتایانش، پتایش   
patâyâneš, patâyeš

Fr.: conservation, préservation   

The act or an instance of conserving.

Verbal noun of → conserve.

conservation law
  قانون ِ پتایش   
qânun-e patâyeš

Fr.: loi de conservation   

A general statement that a → physical quantity, such as → energy, → mass, → momentum, or → electric charge is unchanged in an → interaction occurring within a → closed system. See also:
conservation of charge, → conservation of energy, → conservation of mass, → conservation of mass and energy, → conservation of matter, → conservation of momentum, → conservation of probability, → parity conservation, → conservative field.

conservation; → law.

conservation of charge
  پتایش ِ بار   
patâyeš-e bâr

Fr.: conservation de charge   

In any given → frame of reference, → electric charge is neither created nor destroyed. This → law must not be confused with → charge invariance.

conservation; → charge.

conservation of energy
  پتایش ِ کاروژ   
patâyeš-e kâruž

Fr.: conservation d'énergie   

The → principle whereby the → total energy of a → closed system remains → constant. This means that energy can neither be created nor destroyed. See also the → first law of thermodynamics.

conservation; → energy.

conservation of mass
  پتایش ِ جرم   
patâyeš-e jerm

Fr.: conservation de masse   

A → principle of → classical physics whereby → matter can be neither created nor destroyed. Matter can, however, be → converted into → energy, as predicated by the theory of → special relativity. Also called → conservation of matter.

conservation; → mass.

conservation of mass and energy
  پتایش ِ جرم و کاروژ   
patâyeš-e jerm o kâruž

Fr.: conservation de masse et d'énergie   

A principle, resulting from Einstein's theory of → special relativity whereby in any → closed system the sum of mass and energy remains → constant.

conservation; → mass; → energy.

conservation of matter
  پتایش ِ ماده   
patâyeš-e mâddé

Fr.: conservation de matière   

Same as → conservation of mass.

conservation; → matter.

conservation of momentum
  پتایش ِ جنباک   
patâyeš-e jonbâk

Fr.: conservation de quantité de mouvement   

A fundamental law of physics which states that the momentum of a → physical system does not change in the course of time if there are no external forces acting on the system. It is embodied in → Newton's first law. This principle shows that the interaction of bodies composing a → closed system leads only to an exchange in momentum between the bodies but does not affect the motion of the system as a whole. More specifically, interactions between the composing bodies do not change the velocity of the system's → center of mass.

conservation; → momentum.

conservation of probability
  پتایش ِ شوانایی، پایندگی ِ ~   
-patâyeše šavânâyi, pâyandegi-ye ~

Fr.: conservation de probabilité   

A principle according to which the sum of probabilities of all possible states that might come out of an initial state equals the probability of the initial state.

conservation; → probability.

conservatism
  پتایشگرایی   
patâyešgerâyi

Fr.: conservatisme   

The disposition, or political philosophy, to preserve the existing or traditional order and oppose radical change.

conservative; → -ism.

conservative
  پتایش‌مند   
patâyešmand

Fr.: conservateur   

1) Physics: Of or pertaining to a law of → conservation.
2) Opposed to change and innovation and disposed to keep existing values.
3) Of or relating to a philosophy of → conservatism.
4) An adherent or advocate of political conservatism.

M.Fr. conservatif, from L.L. conservativus, from L. conservatus, p.p. of conservare, → conserve.

Pâyešmand, from pâyeš, → conservation, + -mand possession suffix, → -ist.

conservative field
  میدان ِ پتایش‌مند   
meydân-e patâyešmand

Fr.: champ conservatif   

A → field of → force in which the → work done in taking a particle from one point to another is independent of the → path taken between them. Examples are → electrostatic field and → gravitational field.

conservative; → field.

conservative system
  راژمان ِ پتایش‌مند   
râžmân-e patâyešmand

Fr.: système conservatif   

A system in which there is no dissipation of energy so that the total energy remains unchanged with time.

conservativesystem.
