quantum theory of light
101Classical field theory — A classical field theory is a physical theory that describes the study of how one or more physical fields interact with matter. The word classical is used in contrast to those field theories that incorporate quantum mechanics (quantum field… …
102Detective quantum efficiency — The detective quantum efficiency (often abbreviated as DQE) is a measure of the combined effects of the signal (related to image contrast) and noise performance of an imaging system, generally expressed as a function of spatial frequency. This… …
103Multiangle light scattering — (MALS) is a technique for determining, independently, the absolute molar mass and the average size of particles in solution, by detecting how they scatter light. Collimated light from a laser source is most often used, in which case the technique …
104Perceptual control theory — (PCT) is a psychological theory of animal and Human behavior originated by maverick scientist William T. Powers. In contrast with other theories of psychology and behavior, which assume that behavior is a function of perception that perceptual… …
105electroweak theory — /i lek troh week /, Physics. a gauge theory that unifies quantum electrodynamics with the theory of weak interactions. Also called Salam Weinberg theory, Weinberg Salam theory. Cf. intermediate vector boson. [1975 80; ELECTRO + WEAK; alternate… …
106Multiple-prism dispersion theory — The first description of multiple prism arrays, and multiple prism dispersion, was given by Newton in his book Opticks.[1] Prism pair expanders were introduced by Brewster in 1813.[2] A modern mathematical description of the single prism… …
107Jesus myth theory — The Resurrection of Christ by Noel Coypel (1700). Jesus myth theorists see this as one of a number of stories about dying and rising gods. Description The …
108Wheeler–Feynman absorber theory — The Wheeler–Feynman absorber theory is an interpretation of electrodynamics that starts from the idea that a solution to the electromagnetic field equations has to be symmetric with respect to time inversion, as are the field equations themselves …
109Soft-collinear effective theory — In quantum field theory, soft collinear effective theory (or SCET) is a theoretical framework for doing calculations in quantum chromodynamics (QCD) that involve interacting particles carrying widely different energies.The motivation for… …
110Coherence theory — In physics, coherence theory is the study of optical effects arising from partially coherent light and radio sources. Partially coherent sources are sources where the coherence time or coherence length are limited by bandwidth, by thermal noise,… …
