Physical theories modified by general relativity — This article will use the Einstein summation convention. The theory of general relativity required the adaptation of existing theories of physical, electromagnetic, and quantum effects to account for non Euclidian geometries. These physical… … Wikipedia
T-symmetry — is the symmetry of physical laws under a time reversal transformation mdash;: T: t mapsto t.Although in restricted contexts one may find this symmetry, the universe itself does not show symmetry under time reversal. This is due to the uncertainty … Wikipedia
Scalar-tensor theory — Scalar tensor theories are theories that include a scalar field as well as a tensor field to represent an interaction, especially the gravitational one. Tensor fields and field theory Modern physics tries to derive all physical theories from as… … Wikipedia
Structure tensor — Structure tensors (or second moment matrices) are matrix representations of partial derivatives. In the field of image processing and computer vision, they are typically used to represent gradients, edges or similar information. Structure tensors … Wikipedia
Inversion transformation — Inversion transformations are a natural extension of Poincaré transformations to include all conformal one to one transformations on coordinate space time. They are less studied in physics because unlike the rotations and translations of Poincaré … Wikipedia
Stark effect — The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external static electric field. The amount of splitting and or shifting is called the Stark splitting or Stark shift. In general one … Wikipedia
Coleman–Weinberg potential — The Coleman–Weinberg model represents quantum electrodynamics of a scalar field in four dimensions. The Lagrangian for the model is where the scalar field is complex, is the electromagnetic field tensor, and the covariant derivative containing… … Wikipedia
