positronium pozitroniom Fr.: positronium 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. |
potential density cagâli-ye tavand Fr.: densité potentielle Of a fluid parcel at pressure P, the density that it would acquire if adiabatically brought to a reference pressure. |
power spectral density cagâli-ye binâbi-ye tavân Fr.: densité spectrale de puissance Same as → spectral density. |
preposition pišhel Fr.: préposition A word used with a noun or pronoun to mark its relation with another word.

Also known as → density function, frequency function, → probability function. → probability; → density; → function. |
proposition farâhel, gozâré (#) Fr.: proposition 1) The act of offering or suggesting something to be considered,

propositional logic guyik-e gozâre-yi, ~ gozaarehâ Fr.: logique propositionnelle A branch of logic that deals with the → truth values of logical statements (→ sentences, → propositions) and uses → logical connectives to build more complex → expressions. The distinctive feature of propositional logic is that it does not deal with logical relationships and properties that involve the parts of a statement smaller than the simple statements making it up. The propositions are evaluated as → true or → false. A more expressive system is provided by the → first-order logic. → proposition; → -al; → logic. |
propositional symbol nemâd-e gozâreyi Fr.: symbole propositionnel An upper case letter, e.g. "A," "B," "C," etc. representing a → proposition. Propositional symbols are divisible into two sorts: → propositional constants and → propositional variables. → propositional; → symbol. |
propositional variable vartande-ye gozâre-yi Fr.: variable propositionnel Logic: A → propositional symbol that represents any → proposition whatsoever. → propositional; → variable. |
