Fr.: asymétrie positive
Of a distribution function, a skewness in which the right tail (tail at the large end of the distribution) is more pronounced than the left tail (tail at small end of the distribution). → negative skewness.
The quality or state of being positive; positivity.
Any doctrine that excludes a priori affirmations and admits only positive truth, i.e. factual knowledge gained through observation.
The → antiparticle of the → electron, which has the same → mass, → spin, and → electric charge as the electron, but the charge is → positive. Positrons may be generated by → radioactive decay or by → pair production from energetic → gamma ray photons.
A short-lived bound state of a positron and an electron.
From → positron + -ium (as in barium, titanium), from N.L., from L. neuter suffix.
1) To have as belonging to one; have as property; own.
M.E. possesen, from M.Fr. possesser, "to have and hold, take, be in possession of," from L. possess-, p.p. stem of possidere "to have and hold, be master of, own," probably a compound of potis "having power, powerful, able," from PIE root *poti- "powerful; lord;" from which also derived Skt. patih "master, husband," Gk. posis, Lithuanian patis "husband" + sedere, from PIE root *sed-, "to → sit."
Dâreštidan, infinitive and back formation from dârešt, → possession.
1) The act or fact of possessing; the state of being possessed.
Dârešt, verbal noun of dâštan "to have, possess" (on the model of konešt, from kardan; xoršt, from xordan; bâlešt, from bâlidan; râmešt, from râmidan; (Lori) zenešt, from zadan; (Nowdân, Fârs) perešt, from paridan); Mid.Pers. dâr-, dâštan "to have, hold, preserve;" O.Pers./Av. dar- "to hold, keep back, maintain, keep in mind;" Skt. dhr- "to hold, keep, preserve," dharma- "what is established or firm; law;" Gk. thronos "elevated seat, throne," L. firmus "firm, stable," Lith. daryti "to make," PIE *dher- "to hold, support."

Same as → genitive case.
The state or fact of being possible. Something possible.
1) Capable of happening or likely to happen in the future.
M.E., from L. possibilis "that may be done," from posse "to be able" + -ibilis "-able."
Šodani "possible, practicable," from šodan "to become, to be, to be doing, to go, to pass," from Mid.Pers. šudan, šaw- "to go;" Av. š(ii)auu-, šiyav- "to move, go," šiyavati "goes," šyaoθna- "activity; action; doing, working;" O.Pers. šiyav- "to go forth, set," ašiyavam "I set forth;" cf.

1a) An online message that is submitted to a message board or electronic mailing list.
M.E., from O.E. post "pillar, doorpost," and O.Fr. post "post, upright beam," both from L. postis "post, doorpost."
pasâ- (#), pas- (#)
A prefix, meaning "behind, after, later, subsequent to, posterior to."
From L. post (adverb and preposition) "behind, after, afterward," cognate with Gk. (Arcadian and Cyprian dialects) pos "toward, on, at;" Skt. paśca "behind, after, later."
Pasâ-, from pas "behind" (e.g.: pas-e pardé "behind the curtain"), variant pošt "back; the back; behind;" Mid.Pers. pas "behind, before, after;" O.Pers. pasā "after;" Av. pasca "behind (of space); then, afterward (of time);" cf. Skt. paścā "behind, after, later;" L. post, as above; O.C.S. po "behind, after;" Lith. pas "at, by;" PIE *pos-, *posko-.
post-asymptotic giant branch star (post-AGB)
setâre-ye pasâ-šâxe-ye qulân-e nâhamsâvi
Fr.: étoile post-asymptotique
A star in a short-lived evolutionary stage evolving from the → asymptotic giant branch toward higher → effective temperatures. The majority of low and intermediate mass stars (1 to 8 → solar masses) are believed to pass through this stage on their way to becoming → planetary nebulae.
post-main sequence star
setâre-ye pasâ-rešte-ye farist
Fr.: étoile post séquence principale
A star that has evolved off the → main sequence.
Fr.: développement post-newtinien
Fr.: formalisme post-newtonien
An approximate version of → general relativity that applies when the → gravitational field is → weak, and the matter → velocity is → small. Post-Newtonian formalism successfully describes the gravitational field of the solar system. It can also be applied to situations involving compact bodies with strong internal gravity, provided that the mutual gravity between bodies is weak. It also provides a foundation to calculate the → gravitational waves emitted by → compact binary star systems, as well as their orbital evolution under radiative losses. The formalism proceeds from the Newtonian description and then, step by step, adds correction terms that take into account the effects of general relativity. The correction terms are ordered in a systematic way (from the largest effects to the smallest ones), and the progression of ever smaller corrections is called the → post-Newtonian expansion.
The stage following a nova outburst, when the star has returned to a quiescent state.
post-planetary nebula star
setâre-ye pasâ-miq-e sayyâre-yi
Fr.: étoile post-nébuleuse planétaire
An evolved star whose → planetary nebula has dissipated.
Any of a number of trends or styles in architecture, philosophy, literature, and art developed in the latter part of the 20th century often in reaction to → modernism. In philosophy, postmodernists claim that value systems are concoctions of human partial knowledge rather than systems reflecting universal objective truth. The most influential early postmodern philosophers include Jean Baudrillard, Jean-François Lyotard, and Jacques Derrida.
The term postmodernism was first coined by architects to designate an architectural response against the earlier Bauhaus style, which was characterized by box-like apartment buildings, the absence of ornamentation and harmony between the function of a building and its design; → post- + → modernism.
