Antiresonance Antiresonance In the physics of coupled oscillators, antiresonance, by analogy with resonance, is a pronounced minimum in the amplitude of one oscillator at a particular frequency, accompanied by a large shift in its oscillation phase. Such frequencies are known as the system's antiresonant frequencies, and at these frequencies the oscillation amplitude can drop to almost zero. Antiresonances are caused by destructive interference, for example between an external driving force and interaction with another oscillator. Antiresonances can occur in all types of coupled oscillator systems, including mechanical, acoustic, electromagnetic and quantum systems. They have important applications in the characterization of complex
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. Metaphor in philosophy Metaphor, the description of one thing as something else, has become of interest
