71Nonuniform rational B-spline — Non uniform rational B spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces. History Development of NURBS (Non Uniform Rational Basis Spline) began in the 1950s by engineers …
72Non-uniform rational B-spline — Three dimensional NURBS surfaces can have complex, organic shapes. Control points influence the directions the surface takes. The outermost square below delineates the X/Y extents of the surface …
73Polarizable vacuum — In theoretical physics, particularly fringe physics, polarizable vacuum (PV) most often refers to a proposal by Harold Puthoff to develop an analogue of general relativity to describe gravity in optics like terms. Puthoff himself has apparently… …
74Earth's magnetic field — Computer simulation of the Earth s field in a normal period between reversals.[1] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and… …
75Membrane potential — Differences in concentration of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Many ions have a concentration gradient across the membrane, including potassium (K+), which is at a high inside and a… …
76ParaView — Infobox Software name = ParaView caption = author = developer = Sandia National Labs, Kitware Inc, Los Alamos National Labs. released = latest release version = 3.2.1 latest release date = operating system = Unix/Linux, Mac OS X, Microsoft… …
77Force — For other uses, see Force (disambiguation). See also: Forcing (disambiguation) Forces are also described as a push or pull on an object. They can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate …
78Weyl tensor — In differential geometry, the Weyl curvature tensor, named after Hermann Weyl, is a measure of the curvature of spacetime or, more generally, a pseudo Riemannian manifold. Like the Riemann curvature tensor, the Weyl tensor expresses the tidal… …
79Force-free magnetic field — A force free magnetic field is a type of field which arises as a special case from the magnetostatic equation in plasmas. This special case arises when the plasma pressure is so small, relative to the magnetic pressure, that the plasma pressure… …
80Divided differences — In mathematics divided differences is a recursive division process. The method can be used to calculate the coefficients in the interpolation polynomial in the Newton form. Contents 1 Definition 2 Notation 3 Example …
