111Oscillatory universe — The oscillatory universe is a cosmological model, originally derived by Alexander Friedman in 1922, investigated briefly by Einstein in 1930 and critiqued by Richard Tolman in 1934, in which the universe undergoes a series of oscillations, each… …
112Normal mode — For other types of mode, see Mode (disambiguation). Vibration of a single normal mode of a circular disc with a pinned boundary condition along the entire outer edge. See other modes. A normal mode of an oscillating system is a pattern of motio …

114Escapement — redirects here. For the fisheries term for the stock surviving fishing pressures over a spawning cycle, see Spawn (biology). For other uses, see Escapement (disambiguation). A deadbeat escapement, used in many pendulum clocks. Click above to see… …
115Free electron model — In three dimensions, the density of states of a gas of fermions is proportional to the square root of the kinetic energy of the particles. In solid state physics, the free electron model is a simple model for the behaviour of valence electrons in …
116Electric toothbrush — An electric toothbrush is a toothbrush that uses electric power to move the brush head, normally in an oscillating pattern, though electric toothbrushes are often called rotary toothbrushes. History Dr. Scott s electric toothbrush In the late… …
117Rheometer — Today, a rheometer is a laboratory device used to measure the way in which a liquid, suspension or slurry flows in response to applied forces. It is used for those fluids which cannot be defined by a single value of viscosity and therefore… …
118Ayanamsa — is the Sanskrit term for the longitudinal difference between the tropical or Sayana and sidereal or Nirayana zodiacs. It is defined as the angle by which the sidereal ecliptic longitude of a celestial body is less than its tropical ecliptic… …
119Wire saw — A wire saw A wire saw is a machine using a metal wire or cable for cutting. There are two types of wire saw machines: continuous (or endless or loop) and oscillating (or reciprocating). Sometimes the wire itself is referred to as a blade . The… …
120Jaynes-Cummings model — The Jaynes Cummings model (JCM) is a theoretical model in quantum optics. It describes the system of a two level atom interacting with a quantized mode of an optical cavity, with or without the presence of light. The JCM is of great interest in… …
