51Rindler coordinates — In relativistic physics, the Rindler coordinate chart is an important and useful coordinate chart representing part of flat spacetime, also called the Minkowski vacuum. The Rindler chart was introduced by Wolfgang Rindler. The Rindler coordinate… …
52Upper Convected Maxwell model — The Upper Convected Maxwell model (or UCM model) is a generalisation of the Maxwell material for the case of large deformations using the Upper convected time derivative. The model was proposed by J. G. Oldroyd.The model can be written as::… …
53Coordenadas de Rindler — En física relativista, la carta de coordenadas de Rindler es una importante y útil carta de coordenadas representando parte del espaciotiempo plano, también llamado el vacío de Minkowski. La carta de Rindler fue introducida por Wolfgang Rindler.… …
54Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… …
55Compact quantum group — In mathematics, a compact quantum group is an abstract structure on a unital separable C* algebra axiomatized from those that exist on the commutative C* algebra of continuous complex valued functions on a compact quantum group. The basic… …
56On shell renormalization scheme — In quantum field theory, and especially in quantum electrodynamics, the interacting theory leads to infinite quantities that have to be absorbed in a renormalization procedure, in order to be able to predict measurable quantities. The… …
57Relatividad general — Algunas partes de este artículo pueden resultar complicadas, en ese caso se recomienda Introducción a la relatividad general Representación artística de la explosión de la supernova SN 2006gy, situada a 238 millones de años luz. De ser válido el… …
58Introducción matemática a la relatividad general — La teoría de la relatividad general es una teoría métrica de la gravitación que incorpora además una descripción básica de los sistemas de referencia totalmente generales. Matemáticamente la teoría de la relatividad describe los efectos del campo …
59Eddy current — This article is about the electrical phenomenon. For the Ted McKeever comic, see Eddy Current (comics). Electromagnetism …
60Metamaterial — Negative index metamaterial array configuration, which was constructed of copper split ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3 by 20×20 unit cells with overall dimensions …
