111Centrifugal force (rotating reference frame) — This article is about the fictitious force related to rotating reference frames. For other uses, see Centrifugal force. Classical mechanics …
112Triangulation — In trigonometry and geometry, triangulation is the process of determining the location of a point by measuring angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly. The point can… …
113architecture — /ahr ki tek cheuhr/, n. 1. the profession of designing buildings, open areas, communities, and other artificial constructions and environments, usually with some regard to aesthetic effect. Architecture often includes design or selection of… …
114Differential geometry — A triangle immersed in a saddle shape plane (a hyperbolic paraboloid), as well as two diverging ultraparallel lines. Differential geometry is a mathematical discipline that uses the techniques of differential and integral calculus, as well as… …

116Spacetime — For other uses of this term, see Spacetime (disambiguation). Two dimensional analogy of spacetime distortion. Matter changes the geometry of spacetime, this (curved) geometry being interpreted as gravity. White lines do not represent the… …
117Dromaeosauridae — Deuterostomia Dromaeosaurids Temporal range: Middle Jurassic – Late Cretaceous, 164–65.5 Ma …
118Gravitropism — [or geotropism ] is a turning or growth movement by a plant or fungus in response to gravity. Charles Darwin was one of the first Europeans to document that roots show positive gravitropism and stems show negative gravitropism . That is, roots… …
119Meander — For other uses, see Meander (disambiguation). A hypothetical stream bed following a tilted valley. The maximum gradient is along the down valley axis represented by a hypothetical straight channel. Meanders develop, which lengthen the course of… …
120Osculating orbit — In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space (at a given moment of time) is the gravitational Kepler orbit (i.e. ellipse or other conic) that it would have about its central body (corresponding to… …
