    • P the sixteenth letter of the English alphabet, is a nonvocal consonant whose form and value come from the Latin, into which language the letter was brought, through the ancient Greek, from the Phœnician, its probable origin being Egyptian. Etymologically P is most closely related to bf, and v; as hobble, hopple; father, paternal; recipient, receive. See B F, and M.

  • Interesting fact: The dioxin 2,3,7,8-tetrachlorodibenzo-p-dioxin is 150,000 times deadlier than cyanide.
    • p The sixteenth letter and twelfth consonant of the English alphabet, having a corresponding position in other alphabets. The scheme of parallel forms, as given in the case of the other letters (see especially A), is as follows: The usual Greek II was made by extending the originally short second perpendicular limb; the Latin (whence our) P, by curving the same around to meet the perpendicular (see R). P in all these alphabets stands for the same unvarying sound: namely, for the surd labial mute (corresponding to b as sonant, and m as nasal), made with closure of the lips, during the maintenance of which closure there is complete silence, its character being brought to light by explosion upon the following sound. The p-sound is in English much less common (below a third) than the t-sound, and slightly less common (about four fifths) than the k-sound. The character p has no varieties or irregularities of pronunciation in English save as it is silent at the beginning of a few Greek words, as psalm, pneumatic, pteropod, and, much more rarely, elsewhere, as in receipt, accompt. It enters into one important digraph, namely ph, found in numerous words of classical origin, and pronounced as f (but originally as written, or as an aspirated p, a p with an audible h after it, as in our compound uphill). (See ph.) According to the general law of correspondence, a p in the Germanic part of our language should represent an original b; but b appears to have been almost altogether wanting in the primitive language of our family; and hence our p, when not of classical origin, or borrowed from elsewhere, is the result of some irregular process.

This notation was introduced by Euler. The other form of the Greek minuscule, ω%26, denotes in astronomy the longitude of the perihelion.

Eyes must dim, and hair turn gray,
Age bring wrinkles, p'rhaps repentance;

And that time when youth has went hence,
We - and love - have had our day.

I want to see Marindy and he'p her with her sewin',
And hear her talk so lovin' of her man that's dead and gone,
And stand up with Emanuel to show me how he's growin',
And smile as I have saw her 'fore she putt her mournin' on.

And the pitiful scene did the spectators' hearts appal;
But the most painful case was the mother of J. P. Scarlet,

Consequently the probability distribution, P (p), is transformed into ˜P ( ˜p) = P (1− p) and the random system is self-dual, if the probability distribution is symmetric: P (p) = P (1 − p) and thus the average value of p is given by hpi = pc = 1/2.
