113Gravitational well — In physics, a gravity well is the gravitational potential field around a massive body (a particular kind of potential well). Physical models of gravity wells are sometimes used to illustrate orbital mechanics. Gravity wells are frequently… …
114Orders of magnitude (pressure) — This is a tabulated listing of the orders of magnitude in relation to pressure expressed in pascals. Magnitude Pressure lbf/in2 or dB Item 10−13 Pa 0.1 pPa Interstellar space pressure (approximate) 10 …
115Klein model — In geometry, the Klein model, also called the projective model, the Beltrami–Klein model, the Klein–Beltrami model and the Cayley–Klein model, is a model of n dimensional hyperbolic geometry in which the points of the geometry are in an n… …
116IPv4 address exhaustion — IP address exhaustion refers to the decreasing supply of unallocated IPv4 addresses. This depletion has been a concern since the 1980s when the Internet started to experience dramatic growth. As a result, this has been the driving factor in… …
117Spinors in three dimensions — In mathematics, the spinor concept as specialised to three dimensions can be treated by means of the traditional notions of dot product and cross product. This is part of the detailed algebraic discussion of the rotation group… …
118photochemical reaction — Chemical reaction initiated by absorption of energy in the form of visible (light), ultraviolet, or infrared radiation. Primary photochemical processes occur as an immediate result, and secondary processes may follow. The most important example… …
119Life Sciences — ▪ 2009 Introduction Zoology In 2008 several zoological studies provided new insights into how species life history traits (such as the timing of reproduction or the length of life of adult individuals) are derived in part as responses to… …
120Density on a manifold — In mathematics, and specifically differential geometry, a density is a spatially varying quantity on a differentiable manifold which can be integrated in an intrinsic manner. Abstractly, a density is a section of a certain trivial line bundle,… …
