Anharmonic Oscillator
In classical mechanics, anharmonicity is the Deviation (statistics), deviation of a system from being a harmonic oscillator. An oscillator that is not oscillating in simple harmonic motion, harmonic motion is known as an anharmonic oscillator where the system can be approximated to a harmonic oscillator and the anharmonicity can be calculated using perturbation theory. If the anharmonicity is large, then other numerical analysis, numerical techniques have to be used. In reality all oscillating systems are anharmonic, but most approximate the harmonic oscillator the smaller the amplitude of the oscillation is. As a result, oscillations with frequencies 2\omega and 3\omega etc., where \omega is the fundamental frequency of the oscillator, appear. Furthermore, the frequency \omega deviates from the frequency \omega_0 of the harmonic oscillations. See also intermodulation and combination tone, combination tones. As a first approximation, the frequency shift \Delta \omega=\omega-\om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potential Approximation
Potential generally refers to a currently unrealized ability. The term is used in a wide variety of fields, from physics to the social sciences to indicate things that are in a state where they are able to change in ways ranging from the simple release of energy by objects to the realization of abilities in people. The philosophy, philosopher Aristotle incorporated this concept into his theory of potentiality and actuality, a pair of closely connected principles which he used to analyze Motion (physics), motion, Four causes, causality, Aristotelian ethics, ethics, and physiology in his ''Aristotelian physics, Physics'', ''Metaphysics (Aristotle), Metaphysics'', ''Nicomachean Ethics'', and ''De Anima'', which is about the human Psyche (psychology), psyche. That which is potential can theoretically be made actual by taking the right action; for example, a boulder on the edge of a cliff has potential to fall that could be actualized by pushing it over the edge.
