71Form factor (Quantum Field Theory) — In effective field theory, a form factor is a function which gives the properties of a certain particle interaction without including all of the underlying physics. It is measured experimentally when a theoretical calculation is unavailable or… …
72Field of values — In matrix theory, the field of values associated with a matrix is the image of the unit sphere under the quadratic form induced by the matrix. More precisely, suppose A is a square matrix with complex entries. The field of values for A is the set …
73Field trip — A field trip is a journey by a group of people to a place away from their normal environment.The purpose of the trip is usually observation for education, non experimental research or to provide students with experiences outside their everyday… …
74field archery — ▪ sport also called roving form of archery in which targets of different sizes or shapes are placed at varying distances in uneven, often wooded, terrain in an attempt to simulate hunting conditions. As an organized sport it dates from… …
75field-emission microscope — noun electron microscope used to observe the surface structure of a solid • Hypernyms: ↑electron microscope * * * /feeld i mish euhn/ a device in which electrons liberated by field emission are accelerated toward a fluorescent screen to form a… …
76Field trace — In mathematics, the field trace is a linear mapping defined for certain field extensions. If L / K is a finite Galois extension, it is defined for α in L as the sum of all the conjugates: g (α)of α, for g in the Galois group G of L over K . It is …
77Field Programmable Analog Array — Eine feldprogrammierbare Analoganordnung (FPAA, engl. field programmable analog array) ist ein frei programmierbarer analoger Schaltkreis, konstruiert nach dem Vorbild der FPGAs. Ein FPAA besteht aus einer Matrix von konfigurierbaren analogen… …
78field sports — The main field sports in Britain are hunting, shooting and fishing. They are often also called blood sports because they involve killing animals. All three sports were traditionally associated with the upper classes, although today they all,… …
79field emission display — noun a flat panel display technology that uses large area field electron sources to provide electrons that strike coloured phosphors to produce a colour image. In a general sense, an FED consists of a matrix of cathode ray tubes, each tube… …
80Field, John — (1545–88) Polemicist. Field was educated at the University of Oxford. After ordination, he became known as a leading Puritan in London. After being barred from preaching, he produced an Admonition to Parliament with Thomas Wilcox. In this… …
