Angular eccentricity — In the study of ellipses and related geometry, various parameters in the distortion of a circle into an ellipse are identified and employed: Aspect ratio, flattening and eccentricity. All of these parameters are ultimately trigonometric functions … Wikipedia
Degree Angular Scale Interferometer — The Degree Angular Scale Interferometer (DASI) was a telescope located in Antarctica. It was a 13 element interferometer operating between 26 and 36 GHz in ten bands. The instrument is similar in design to the Cosmic Background Imager and… … Wikipedia
Clebsch–Gordan coefficients — In physics, the Clebsch–Gordan coefficients are sets of numbers that arise in angular momentum coupling under the laws of quantum mechanics. In more mathematical terms, the CG coefficients are used in representation theory, particularly of… … Wikipedia
Velocidad de transmisión — Para otros usos de este término, véase Velocidad de transmisión de datos. Relación de transmisión, tangencial sin deslizar … Wikipedia Español
Rigid rotor — The rigid rotor is a mechanical model that is used to explain rotating systems. An arbitrary rigid rotor is a 3 dimensional rigid object, such as a top. To orient such an object in space three angles are required. A special rigid rotor is the… … Wikipedia
Clebsch-Gordan coefficients — In physics, the Clebsch Gordan coefficients are sets of numbers that arise in angular momentum coupling under the laws of quantum mechanics. In more mathematical terms, the CG coefficients are used in representation theory, particularly of… … Wikipedia
Harmonic oscillator — This article is about the harmonic oscillator in classical mechanics. For its uses in quantum mechanics, see quantum harmonic oscillator. Classical mechanics … Wikipedia
Wigner D-matrix — The Wigner D matrix is a matrix in an irreducible representation of the groups SU(2) and SO(3). The complex conjugate of the D matrix is an eigenfunction of the Hamiltonian of spherical and symmetric rigid rotors. Definition Wigner D matrix Let j … Wikipedia
Semicircular potential well — In quantum mechanics, the case of a particle in a one dimensional ring is similar to the particle in a box. The particle follows the path of a semicircle from 0 to pi where it cannot escape, because the potential from pi to 2 pi is infinite.… … Wikipedia
Spin (physics) — This article is about spin in quantum mechanics. For rotation in classical mechanics, see angular momentum. In quantum mechanics and particle physics, spin is a fundamental characteristic property of elementary particles, composite particles… … Wikipedia
