Fr.: test d'hypothèse statistique   

A method of making decision between rejecting or not rejecting a → null hypothesis on the basis of a set of observations.

statistical; → hypothesis; → test.

stellar nucleosynthesis
  هسته‌هندایش ِ ستاره‌ای   
haste-handâyeš-e setâre-yi

Fr.: nucléosynthèse stellaire   

The → nuclear reaction process taking place inside stars, whereby → chemical elements are produced from pre-existing nuclei heavier than → hydrogen and → helium.

stellar; → nucleosynthesis.

stellar population synthesis
  هندایش ِ پرینش‌های ِ ستاره‌ای   
handâyeš-e porinešhâ-ye setâre-yi

Fr.: synthèse de poupulations stellaires   

A theoretical model that reconstructs the integrated spectrum of → stellar populations from an empirical library of stellar spectra containing the range of types expected to be present in the sample. The light received from a given galaxy is emitted by a large number of stars that may have different masses, ages, and metallicities. Stellar population synthesis models are tools for interpreting the integrated light that we observe from the galaxies.

stellar; → population; → model.

synthesis
  هندایش   
handâyeš

Fr.: synthèse   

The combining of the constituent elements of separate materials or abstract entities into a single or unified entity; opposite of → analysis. → aperture synthesis; → nucleosynthesis.

From L. synthesis "collection, set," from Gk. synthesis "composition," from syntithenai "put together, combine," from → syn- "together" + tithenai "to put, place," from PIE base *dhe- "to put, to do," cf. Pers. dâdan "to give," as below.

1) dâyan 2) dâyan-nâme, pâyân-nâme

Fr.: thèse   

1) A proposition put forward for consideration, especially one to be discussed and proved or to be maintained against objections.
Philo.: The first of three stages in Hegelian dialectic; the inevitable transition of thought, by contradiction and reconciliation, from an initial conviction to its opposite and then to a new, higher conception that involves but transcends both of them. → antithesis; → synthesis.
2) A dissertation based on original research, especially as work toward an academic degree.

M.E., from L., from Gk. thesis "a proposition; a setting down, something set down," from root of tithenai "to place, put, set," cognate with Pers. dâdan "to give," as below.

1) Dâyan "giving, setting down," from O.Pers./Av. dā- "to give, grant, put," dadāiti "he gives;" Mid.Pers./Mod.Pers. dâdan "to give; to put" (cf. Skt. dadáti "he gives;" Gk. tithenai "to place, put, set," didomi "I give;" L. dare "to give, offer;" Rus. delat' "to do;" O.H.G. tuon, Ger. tun, O.E. don "to do;" PIE base *dhe- "to put, to do") + -y- epenthetic vowel + -an noun/adjective suffix appearing in many words (such as rowzan, mihan, barzan, rasan, barzan, rowšan).
