1Leading edge extension — Leading edge extensions or LEX (also referred to as leading edge root extensions or LERX or strakes or chines ) are fillets added to the front of a modern fighter aircraft s wings in order to provide usable airflow at high angles of attack. They… …
2Principle of least action — This article discusses the history of the principle of least action. For the application, please refer to action (physics). In physics, the principle of least action or more accurately principle of stationary action is a variational principle… …
3Principle of original horizontality — A stratigraphic section of Ordovician rock exposed in central Tennessee, USA. The sediments composing these rocks were formed in an ocean and deposited in horizontal layers …
4Correspondence principle — This article discusses quantum theory and relativity. For other uses, see Correspondence principle (disambiguation). In physics, the correspondence principle states that the behavior of systems described by the theory of quantum mechanics (or by… …
5Anthropic principle — In astrophysics and cosmology, the anthropic principle is the philosophical argument that observations of the physical Universe must be compatible with the conscious life that observes it. Some proponents of the argument reason that it explains… …
6Bernoulli's principle — This article is about Bernoulli s principle and Bernoulli s equation in fluid dynamics. For Bernoulli s Theorem (probability), see Law of large numbers. For an unrelated topic in ordinary differential equations, see Bernoulli differential… …
7Coulter principle — Coulter patented several different implementations of the Coulter Principle. Image taken from US Patent #2,656,508. The term “Coulter Principle” refers to the use of an electric field for counting and sizing dilute suspensions of particles in… …
8Fermat's principle — In optics, Fermat s principle or the principle of least time is the idea that the path taken between two points by a ray of light is the path that can be traversed in the least time. This principle is sometimes taken as the definition of a ray of …
9On the Fourfold Root of the Principle of Sufficient Reason — On the Fourfold Root of the Principle of Sufficient Reason[1] was originally published as a doctoral dissertation in 1813. The German philosopher Arthur Schopenhauer revised this important work and re published it in 1847. Throughout all… …
10Pauli exclusion principle — Physics. See exclusion principle. [1925 30; named after W. PAULI] * * * Assertion proposed by Wolfgang Pauli that no two electrons in an atom can be in the same state or configuration at the same time. It accounts for the observed patterns of… …
