There are two kinds of reciprocity failure. They are both related to poor efficiency of utilizing photoelectrons to create latent image centers.

Famous quotes containing the words reciprocity, law and/or failure:
“Between women love is contemplative; caresses are intended less to gain possession of the other than gradually to re-create the self through her; separateness is abolished, there is no struggle, no victory, no defeat; in exact reciprocity each is at once subject and object, sovereign and slave; duality become mutuality.”
—Simone De Beauvoir (1908–1986)
“There is but one law for all, namely that law which governs all law, the law of our Creator, the law of humanity, justice, equity—the law of nature and of nations.”
—Edmund Burke (1729–1797)
“No failure in America, whether of love or money, is ever simple; it is always a kind of betrayal, of a mass of shadowy, shared hopes.”
—Greil Marcus (b. 1945)
