Field emission — (FE) is the emission of electrons from the surface of a condensed phase into another phase due to the presence of high electric fields. In this phenomenon, electrons with energies below the Fermi level tunnel through the potential barrier at the… … Wikipedia
Dimensional metrology — is the science of calibrating and using physical measurement equipment to quantify the physical size of or distance from any given object. Inspection is a critical step in product development and quality control. Dimensional Metrology requires… … Wikipedia
Dimensional analysis — In physics and all science, dimensional analysis is a tool to find or check relations among physical quantities by using their dimensions. The dimension of a physical quantity is the combination of the basic physical dimensions (usually mass,… … Wikipedia
Field electron emission — It is requested that a diagram or diagrams be included in this article to improve its quality. For more information, refer to discussion on this page and/or the listing at Wikipedia:Requested images. Field emission (FE) (also known as field… … Wikipedia
Field with one element — In mathematics, the field with one element is a suggestive name for an object that should exist: many objects in math have properties analogous to objects over a field with q elements, where q = 1, and the analogy between number fields and… … Wikipedia

Dimensional reduction — This article is on dimensional reduction in physics. For the statistics concept, see Dimensionality reduction. In physics, a theory in D spacetime dimensions can be redefined in a lower number of dimensions d, by taking all the fields to be… … Wikipedia
Dimensional transmutation — In particle physics, dimensional transmutation is a physical mechanism that transforms a dimensionless parameter into a dimensionful parameter. In classical field theory such as gauge theory in four dimensional spacetime, the coupling constant is … Wikipedia
Field of sets — Set algebra redirects here. For the basic properties and laws of sets, see Algebra of sets. In mathematics a field of sets is a pair where X is a set and is an algebra over X i.e., a non empty subset of the power set of X closed under the… … Wikipedia
Dimensional operator — In mathematics, specifically set theory, a dimensional operator on a set E is a function from the subsets of E to the subsets of E. Definition If the power set of E is denoted P(E) then a dimensional operator on E is a map that satisfies the… … Wikipedia
