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
Cassandra (metaphor) applied in a variety of contexts such as psychology, environmentalism, politics, science, cinema, the corporate world, and in philosophy, and has been in circulation since at least 1949 when French philosopher Gaston Bachelard coined the term 'Cassandra Complex' to refer to a belief that things could be known in advance. The Cassandra metaphor is applied by some psychologists to individuals who experience physical and emotional suffering as a result of distressing personal perceptions, and who are disbelieved when they attempt to share the cause of their suffering with others. In 1963, psychologist Melanie Klein provided an interpretation of Cassandra as
