111Stress-energy tensor — The stress energy tensor (sometimes stress energy momentum tensor) is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of …
112Lagrangian — This article is about Lagrange mechanics. For other uses, see Lagrangian (disambiguation). The Lagrangian, L, of a dynamical system is a function that summarizes the dynamics of the system. It is named after Joseph Louis Lagrange. The concept of… …
113Density functional theory — Electronic structure methods Tight binding Nearly free electron model Hartree–Fock method Modern valence bond Generalized valence bond Møller–Plesset perturbation theory …
114Euler angles — The Euler angles were developed by Leonhard Euler to describe the orientation of a rigid body (a body in which the relative position of all its points is constant) in 3 dimensional Euclidean space. To give an object a specific orientation it may… …
115Franck-Condon principle — The Franck Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to… …
116Stationary spacetime — In general relativity, a spacetime is said to be stationary if it admits a global, nowhere zero timelike Killing vector field. In a stationary spacetime, the metric tensor components, g {mu u}, may be chosen so that they are all independent of… …

118Komar mass — Introduction and motivation = The Komar mass of a system is one of several formal concepts of mass that used in general relativity. The Komar mass can be defined in any stationary spacetime, which is a spacetime in which all the metric can be… …
119Fourth dimension — [ tesseract rotating around a plane in 4D.] In physics and mathematics, a sequence of n numbers can be understood as a location in an n dimensional space. When n =4, the set of all such locations is called 4 dimensional space, or, colloquially,… …
