gravity structure
21Surface gravity — The surface gravity, g , of an astronomical or other object is the gravitational acceleration experienced at its surface. The surface gravity may be thought of as the acceleration due to gravity experienced by a hypothetical test particle which… …
22Speed of gravity — In the context of classical theories of gravitation, the speed of gravity refers to the speed at which a gravitational field propagates. This is the speed at which changes in the distribution of energy and momentum result in noticeable changes in …
23List of quantum gravity researchers — This is a list of (some of) the researchers in quantum gravity.* Jan Ambjørn: Expert on dynamical triangulations who helped develop the causal dynamical triangulations approach to quantum gravity. * Abhay Ashtekar: Inventor of the Ashtekar… …
24History of loop quantum gravity — General relativity is the theory of gravitation published by Albert Einstein in 1915. According to it, the force of gravity is a manifestation of the local geometry of spacetime. Mathematically, the theory is modelled after Bernhard Riemann s… …
25Mars Gravity Biosatellite — The Mars Gravity Biosatellite was a project initiated in 2001 by the Mars Society and volunteer students and staff of MIT to build a spacecraft to study the effects of Mars level gravity on mammals. On 24 June 2009, a status report was… …
26Tube (structure) — In structural engineering, the tube is the name given to the systems where in order to resist lateral loads (wind, seismic, etc.) a building is designed to act like a three dimensional hollow tube, hence the name, cantilevered perpendicular to… …
27Constante de structure fine — En physique, la constante de structure fine, représentée par la lettre grecque α, est une constante fondamentale qui régit la force électromagnétique assurant la cohérence des atomes et des molécules. Elle fut proposée en 1916 par le physicien… …
28Dish structure — A dish structure is a secondary sedimentary structure caused by liquefaction and fluidization of the soft sediment. The structure occurs mainly in clastic deposits like turbidites. Contents 1 Terminology 2 History 3 Description …
29Causal structure — This article is about the possible causal relationships among points in a Lorentzian manifold. For classification of Lorentzian manifolds according to the types of causal structures they admit, see Causality conditions. In mathematical physics,… …
30Active structure — An active structure (also known as a smart or adaptive structure) is a mechanical structure with the ability to alter its configuration, form or properties in response to changes in the environment.The term active structure also refers to… …
