He spoke again, hurriedly and excitedly now, but the coherency of his narrative was at an end.
The Customs Union was invented in 1828 to supply the necessary element of coherency.
Taking the ordinary vague meaning of the word "talented," there is no coherency in the picture.
Certainly the coherency of this speech was not on its surface.
And having failed on the Marne and retreated to the Aisne the German strategic plan lost all coherency.
The science loses in coherency from this diversity of definition.
There is no consistency which has not once been inconsistent, nor coherency that has not been incoherent.
To most of them, these impressions never reach the point of coherency.
For the delegates set great store by their reputation for logic and coherency.
But short of this there can be no value in coherency and harmonious consistency as such.
A property holding for two or more waves or fields when each individual wave or field is in phase with every other one. Lasers, for example, emit almost perfectly coherent light; all the photons emitted by a laser have the same frequency and are in phase. Since quantum states can be described by a wave equation, coherence can hold for quantum states in general, though only among bosons. Coherence is generally possible in physical systems that may undergo superposition. Maintaining coherence of light is important in fiber optic communications. See also Bose-Einstein condensate.
