Atomic, molecular, and optical physics the origin of the index of refraction treated an electron in an atomic system classically according to the model of Paul Drude and Hendrik Lorentz. The theory was developed to attempt to provide an origin for the wavelength-dependent refractive index "n" of a material. In this model, incident electromagnetic waves forced an electron bound to an atom to oscillate. The amplitude of the oscillation would then have a relationship to the frequency of the incident electromagnetic wave and the resonant frequencies of the oscillator. The superposition of these emitted waves from many oscillators would then lead to a wave which
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.
