Resonator The guitar resonator is a device for driving guitar string harmonics by an electromagnetic field. This resonance effect is caused by a feedback loop and is applied to drive the fundamental tones, octaves, 5th, 3rd to an infinite sustain. Resonator A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from
Metaphor in philosophy Hegel’s Absolute Consciousness. The main arguments against this universalism invoke metaphor on two related accounts: (1) the fact that key epistemological concepts have metaphors at their root, for example, “mirroring”, “correspondence”, “sense data”, is taken as evidence of the contingent, communal, subjective basis of knowledge, and (2) because metaphor (as a form of dislocated or dislocating predication) works by testing the appropriate with the inappropriate, it is seen as a means of challenging the boundaries whereby one subject defines itself in relation to another.
