In physics, capacity for doing work.
From M.Fr. energie, from L.L. energia, from Gk. energeia "force in action, activity, operation," from energos "active, working," from en- "in, at" + ergon "work," from PIE base *werg- "to work" (cf. Av. varəz- "to work, do, perform, exercise;" Mod.Pers. varz-, varzidan "to labor, exercise, practise;" Arm. gorc "work;" Lith. verziu "tie, fasten, squeeze," vargas "need, distress;" Goth. waurkjan; O.E. wyrcan "work," wrecan "to drive, hunt, pursue").
Kâruž, literally "work strength," from kâr + už. The first component kâr "work," Mid.Pers kâr, Mod./Mid.Pers. kardan "to do, to work," Mid.Pers. kardan; O.Pers./Av. kar- "to do, make, build," Av. kərənaoiti "he makes;" cf. Skt. kr- "to do, to make," krnoti "he makes, he does," karoti "he makes, he does," karma "act, deed;" PIE base kwer- "to do, to make." The second component, už, from Mid.Pers. ôž "strength" (ôžômand "strong"), Av. aogah-, aojah- "strength" (aojahvant- "strong") Skt. ojas- "strength" (ojasvant- "strong"); L. augustus "venerable," L.L. augmentare "to increase," from augere "to increase, enlarge, enrich;" Lith. augu "to grow;" Gk. auxo "increase;" Goth. aukan "to grow, increase;" O.E. eacien "to increase"); PIE *augos- "force," *aug- "to increase."
Fr.: cascade d'énergie
The → turbulent process whereby → kinetic energy is transformed into heat by the action of nonlinear coupling which transfers the energy from large eddies (→ eddy) to smaller and smaller eddies, finally arriving at → dissipative scales dominated by → viscosity (direct cascade). In the simplest case (3D homogeneous hydrodynamic turbulence), the resulting energy distribution is the → Kolmogorov spectrum. The reverse process also exists (inverse cascade) whereby energy is transferred to larger and larger eddies.
Fr.: densité d'énergie
The amount of energy in the form of radiation per unit volume, expressed in ergs cm-3. In particular, the energy density of blackbody radiation at temperature T is aT4, where the radiation constant a = 7.56 × 10-15 erg cm-3 (K)-4.
energy generation equation
hamugeš-e âzâneš-e kâruž
Fr.: équation de génération d'énergie
energy generation rate
nerx-e âzâneš-e kâruž
Fr.: taux de génération d'énergie
Of a stellar → nuclear fusion, the energy produced per unit mass per unit time, usually denoted ε (erg g-1s-1). The general form of the energy generation equation is: ε = ε0ρλTν, where ε0, ρ, and λ are constants over some efficiently restricted range of → temperature T, → density ρ, and → chemical composition. The temperature exponent ν is about 4, 15, and 40 for → proton-proton chain, → CNO cycle, and → triple alpha process, respectively.
Fr.: niveau d'énergie
Any of the several discrete states of energy which a particle, atom, or molecule can adopt under conditions where the possible values are restricted by quantum mechanical laws.
Fr.: spectre d'énergie
Of cosmic rays, the plot representing the number of particles as a function of their energy.
Fr.: état d'énergie
Same as → energy level.
Fr.: transfert d'énergie
Fr.: tenseur énergie-quantité de mouvement
1) Any machine that converts energy, especially heat energy, into mechanical power
M.E. engin, from O.Fr. engin "skill, cleverness; war machine," from L. ingenium "inborn qualities, talent," from → in- "in" + gen-, root of gignere "to beget, produce;" cognate with Pers. zâdan "to bring forth, give birth;" → generate.
Motor, loanword from Fr. moteur, from L. motor "mover," from movere "to move."
A person who designs, constructs, or works with engines or machines.
M.E. engin(e)our, from O.Fr. engigneor, from L.L. ingeniare, → engine.
Mohandes, from Ar. muhandis "measurer," from Pers. andâzé, → measure.
The action, work, or profession of an engineer.
Fr.: monture anglaise
A method of mounting a telescope in which the polar axis is supported at each end by two piers. The great defect of this type of mounting is its inability to observe the pole.
Fr.: rehausser, accroître
To raise to a higher degree; intensify; magnify (Dictionary.com).
M.E. enhauncen, from Anglo-Fr. enhauncer, from O.Fr. enhaucier "make higher, make greater; raise in esteem," from V.L. *inaltiare, from L.L. inaltare "raise, exalt," from altare "make high," from altus "high."
Bolandidan, from boland "high," related to bâlâ "up, above, high, elevated, height," borz, "height, magnitude," → magnitude.
Fr.: rehaussement, accroissement
An increase or improvement in value, extent, or quality.
Verbal noun of → enhance.
From L. aenigma "riddle," from Gk. ainigma "a dark saying, riddle," from ainissesthai "speak obscurely, speak in riddles," from ainos "tale, story; saying, proverb;" of unknown origin.
Câceh, from Baluci (Zâhedân) câcâk "riddle, puzzle;" cf. (Kermânšâhi) câvca "riddle, puzzle" (Fin-e Bandar-Abbâs) cencen "riddle;" maybe related to Choresmian c'tyk "riddle," from Proto-Ir. *caš- "to teach, to show;" Av. *caš- "to teach, to show" (Cheung 2007).
Resembling an enigma, or a puzzling occurrence, situation, statement, person, etc.; perplexing; mysterious (Dictionary.com).
Cušenâk, from cušé, → enigma, + -nâk adj. suffix.
asr-e rowšangari (#)
Fr.: Siècle des Lumières
An intellectual movement in Europe during the 17th and 18th centuries celebrating human reason and scientific thought as the instruments of progress and subjecting conventional ways of thinking to rigorous critique. The Enlightenment culminated with the writings of Jean-Jacques Rousseau (1712-1778) and the Encyclopédistes, the philosophy of Immanuel Kant (1724-1804), and the political ideals of the French and American Revolutions, while the precursor in science and philosophy included Francis Bacon (1561-1626), René Descartes (1596-1650), Isaac Newton (1643-1727), John Locke (1632-1704), and Thomas Hobbes (1588-1679).
