Resonance Resonance In mechanical systems, resonance is a phenomenon that occurs when the frequency at which a force is periodically applied is equal or nearly equal to one of the natural frequencies of the system on which it acts. This causes the system to oscillate with larger amplitude than when the force is applied at other frequencies. Frequencies at which the response amplitude is a relative maximum are known as resonant frequencies or resonance frequencies of the system. Near resonant frequencies, small periodic forces have the ability to produce large amplitude oscillations, due to the storage of vibrational energy. In other
Inside baseball (metaphor) Inside baseball (metaphor) The phrase "inside baseball" is a term used mainly in the United States. It is "a figurative adjective meaning appreciated by only a small group of insiders or aficionados." It usually refers to a detail-oriented approach to the minutiae of a subject, which requires such a specific knowledge about what is being discussed that the nuances are not understood or appreciated by outsiders. According to "Merriam-Webster", the term originated in the 1890s referring to a particular style of playing the game which relied on singles, walks, bunts, and stolen bases rather than power hitting.
