91Naked singularity — In general relativity, a naked singularity is a gravitational singularity, without an event horizon. In a black hole, there is a region around the singularity, the event horizon, where the gravitational force of the singularity is strong enough… …
92Hue — [ thumb|The hues in the image of this Painted Bunting are cyclically rotated with time.] Hue is one of the main properties of a color described with names such as red , yellow , etc. The two other main properties are lightness and colorfulness.… …
93Loop quantum gravity — Not to be confused with the path integral formulation of LQG, see spin foam. This article is about LQG in its Canonical formulation.. Beyond the Standard Model …
94Barotropic vorticity equation — A simplified form of the vorticity equation for an inviscid, divergence free flow, the barotropic vorticity equation can simply be stated as:frac{D eta}{D t} = 0,where frac{D}{D t} is the material derivative and:eta = zeta + fis absolute… …
95Vorticity equation — The vorticity equation is an important prognostic equation in the atmospheric sciences. Vorticity is a vector, therefore, there are three components. The equation of vorticity (three components in the canonical form) describes the total… …
96Transmission electron microscopy — A TEM image of the polio virus. The polio virus is 30 nm in size.[1] Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it… …
97Hooke's law — models the properties of springs for small changes in length Prof. Walter Lewin explains Hooke s law, in …
98Airfoil — An airfoil (in American English) or aerofoil (in British English) is the shape of a wing or blade (of a propeller, rotor or turbine) or sail as seen in cross section. An airfoil shaped body moved through a fluid produces a force perpendicular to… …
99List of electronics topics — Alphabetization has been neglected in some parts of this article (the b section in particular). You can help by editing it. This is a list of communications, computers, electronic circuits, fiberoptics, microelectronics, medical electronics,… …
100Visual system — The visual system includes the eyes, the connecting pathways through to the visual cortex and other parts of the brain. The illustration shows the mammalian system. The visual system is the part of the central nervous system which enables… …
