Gk. pneuma "wind; breath," from pnein "to blow; to breathe;" PIE base *pneu- "to breathe." Related terms in other Indo-European languages: O.E. fnaeran "to breathe heavily," fneosan "to snort, sneeze;" M.H.G. pfnusen, pfnehen "to breathe, pant, sniff, snort, sneeze;" Norw. fnysa "to breeze;" M.Du. fniesen, Du. fniezen "to sneeze;" O.H.G. niosan, Ger. niesen "to sneeze."

inflation
  پندام   
pandâm

Fr.: inflation   

1) General: The act of inflating; the state of being inflated.
2) Cosmology: A brief exponential expansion of the Universe postulated to have occurred 10-35 seconds after the → Big Bang, in response to the separation of the → strong interaction from the → electroweak interaction. This idea aims at explaining the → flatness problem, the → horizon problem, and the → magnetic monopole problem. See also → inflaton field.

Verbal noun of → inflate.

inflationary model
  مدل ِ پندامی   
model-e pandâmi

Fr.: modèle d'inflation   

A class of → Big Bang models of the Universe that include a finite period of accelerated expansion in their early histories. Such an event would have released enormous energy, stored until then in the vacuum of space-time. The horizon of the Universe expanded, temporarily, much faster than the speed of light. → inflaton field.

Inflationary, adj. of → inflation; → model.

inflaton
  اینفلاتون   
inflaton

Fr.: inflaton

inflaton field
  میدان ِ اینفلاتون   
meydân-e inflaton

Fr.: champ inflaton   

A hypothetical → scalar field that provides a theoretical basis for → inflation in the early → Big Bang history of the → Universe. The inflaton field would fill space with the same energy at every point. In general, the scalar field can vary with time and space, though to a first approximation everywhere in the Universe will have the same value at any time. The field has a particle associated with it, called → inflaton, just as the → electromagnetic field is associated with the → photon. The inflaton field is characterized also by a → negative pressure that would yield a tremendous → repulsive gravity during a brief lapse of time. In the earliest moments of the Universe, space is uniformly filled with an inflaton field, whose value places it higher up on its → potential energy curve. The inflaton's → potential energy would drop in a tiny fraction of a second, on the order of 10-35 seconds. And yet, during that brief instant, space would expand by a colossal factor, of at least 1030.

inflaton; → field.

inflect
  درچفتیدن   
darcaftidan

Fr.: mettre une désinence à, fléchir   

1) General: To bend in, to turn from a direct line or course.
2) Grammar: To change the ending or form of a word in accordance with other words in a sentence. To apply → inflection to.
