Entropy (arrow of time) — Entropy is the only quantity in the physical sciences that picks a particular direction for time, sometimes called an arrow of time. As one goes forward in time, the second law of thermodynamics says that the entropy of an isolated system can… … Wikipedia
entropy — entropic /en troh pik, trop ik/, adj. entropically, adv. /en treuh pee/, n. 1. Thermodynam. a. (on a macroscopic scale) a function of thermodynamic variables, as temperature, pressure, or composition, that is a measure of the energy that is not… … Universalium
Entropy — This article is about entropy in thermodynamics. For entropy in information theory, see Entropy (information theory). For a comparison of entropy in information theory with entropy in thermodynamics, see Entropy in thermodynamics and information… … Wikipedia
Conservation of energy — This article is about the law of conservation of GPE in physics. For sustainable energy resources, see Energy conservation. Prof. Walter Lewin demonstrates the conservation of mechanical energy, touching a wrecking ball with his jaw. (MIT Course… … Wikipedia
Entropy (classical thermodynamics) — In thermodynamics, entropy is a measure of how close a thermodynamic system is to equilibrium. A thermodynamic system is any physical object or region of space that can be described by its thermodynamic quantities such as temperature, pressure,… … Wikipedia
Entropy (statistical thermodynamics) — In thermodynamics, statistical entropy is the modeling of the energetic function entropy using probability theory. The statistical entropy perspective was introduced in 1870 with the work of the Austrian physicist Ludwig Boltzmann. Mathematical… … Wikipedia
Introduction to entropy — Thermodynamic entropy provides a measure of certain aspects of energy in relation to absolute temperature. The thermodynamic entropy S, often simply called the entropy in the context of thermodynamics, is a measure of the amount of energy in a… … Wikipedia
History of entropy — The concept of entropy developed in response to the observation that a certain amount of functional energy released from combustion reactions is always lost to dissipation or friction and is thus not transformed into useful work . Early heat… … Wikipedia
GENERIC formalism — In non equilibrium thermodynamics, GENERIC is an acronym for General Equation for Non Equilibrium Reversible Irreversible Coupling. It is the general form of dynamic equation for a system with both reversible and irreversible dynamics (generated… … Wikipedia
