61Axiality and rhombicity — In physics and mathematics, axiality and rhombicity are two characteristics of a symmetric second rank tensor in three dimensional Euclidean space, describing its directional asymmetry. Let A denote a second rank tensor in R3, which can be… …
62Hilbert space — For the Hilbert space filling curve, see Hilbert curve. Hilbert spaces can be used to study the harmonics of vibrating strings. The mathematical concept of a Hilbert space, named after David Hilbert, generalizes the notion of Euclidean space. It… …
63Classification of electromagnetic fields — In differential geometry and theoretical physics, the classification of electromagnetic fields is a pointwise classification of bivectors at each point of a Lorentzian manifold. It is used in the study of solutions of Maxwell s equations and has… …
64Field (physics) — The magnitude of an electric field surrounding two equally charged (repelling) particles. Brighter areas have a greater magnitude. The direction of the field is not visible …
65Change of basis — In linear algebra, change of basis refers to the conversion of vectors and linear transformations between matrix representations which have different bases. Contents 1 Expression of a basis 2 Change of basis for vectors 2.1 Tensor proof …
66Voigt notation — In mathematics, Voigt notation or Voigt form in multilinear algebra is a way to represent a symmetric tensor by reducing its order. There are a few variants and associated names for this idea: Mandel notation, Mandel–Voigt notation and Nye… …
67List of zero terms — The number 0 is an important concept in mathematics.Zero moduleIn mathematics, the zero module is the module consisting of only the additive identity for the module s addition function. In the integers, this identity is zero, which gives the name …
68Piezoelectricity — is the ability of some materials (notably crystals and certain ceramics, including bone) to generate an electric potentialPrinciples of Instrumental Analysis. 6th Edition, 2007. Skoog, Holler, and Crouch. Chapter 1, Sec. 1C 4, Pg. 9.] in response …
69Magnetic field — This article is about a scientific description of the magnetic influence of an electric current or magnetic material. For the physics of magnetic materials, see magnetism. For information about objects that create magnetic fields, see magnet. For …
70Wigner-Eckart theorem — The Wigner Eckart theorem is a theorem of representation theory and quantum mechanics. It states that matrix elements of spherical tensor operators on the basis of angular momentum eigenstates can be expressed as the product of two factors, one… …
