Electrical resistivity and conductivity results in the important concept of "quasineutrality", which says the density of negative charges is approximately equal to the density of positive charges over large volumes of the plasma ("n" = <Z>"n"), but on the scale of the Debye length there can be charge imbalance. In the special case that "double layers" are formed, the charge separation can extend some tens of Debye lengths. The magnitude of the potentials and electric fields must be determined by means other than simply finding the net charge density. A common example is to assume that the electrons satisfy the Boltzmann relation: Differentiating this
Negative and positive atheism no God. He categorizes himself as a "de facto atheist" but "not" a "strong atheist" on this scale. Within negative atheism, philosopher Anthony Kenny further distinguishes between agnostics, who find the claim "God exists" uncertain, and theological noncognitivists, who consider all talk of gods to be meaningless. Jacques Maritain used the negative/positive phrases as early as 1949, but with a different meaning and in the context of a strictly Catholic apologist. Goparaju Ramachandra Rao (1902–1975), better known by his nickname Gora, was an Indian social reformer, anti-caste activist, and atheist. He proposed a philosophy he called "positive atheism", which treated
