Fingrinhoe Roman Site
Fingrinhoe Roman Site is a multi-acre Roman archaeological site in Colchester, Essex, England, possibly a military supply base in use until about A.D. 120, with structures and a possible villa.
Finial
A finial, also called a hip-knob, is a small ornamental terminal placed at the top of a gable, spire, roof ridge, or furniture, defined by position rather than shape.
Finian's Rainbow
Finian's Rainbow: 1947 Broadway musical by Burton Lane, Yip Harburg, and Fred Saidy about a stolen leprechaun's gold in Missitucky; filmed in 1968 by Francis Ford Coppola with Fred Astaire in his last screen musical.
Fininvest
Fininvest is the private holding company of the Berlusconi family, founded by Silvio Berlusconi and headquartered in Milan. Its main assets are stakes in MFE-MediaForEurope, Mondadori, and Banca Mediolanum.
Finis Conner
Finis Conner is an American disk-drive industry executive who helped found Shugart Associates, Seagate Technology in 1979, and Conner Peripherals, which Seagate acquired in 1996.
Finis Ewing
Finis Ewing (1773–1841) was a Presbyterian minister who, with Samuel King and Samuel McAdow, reorganized the Cumberland Presbytery in 1810, founding the Cumberland Presbyterian Church.
Finishing school
Finishing school, also called charm school, is a private school historically teaching young women social graces for polite society; the term now also covers short-term vocational training programs for service-industry employment.
Finistère
Finistère (29) is France's westernmost department, in Brittany, chef-lieu Quimper. 6,733 km², 277 communes, 2,263 km of coast, the most maritime of continental France; 933,455 inhabitants (2023).
Finistere Ventures
Finistere Ventures is a California-based venture capital firm, founded in 2005, that invests in agricultural technology and food companies at the Series A and B stages.
Finite difference
A finite difference, also known as the calculus of differences, is a difference between a function's values at nearby points, used to approximate derivatives numerically.
Finite difference method
The finite difference method (FDM) is a numerical technique for solving differential equations by replacing derivatives with difference quotients on a grid, turning the problem into algebraic equations solved simultaneously.
Finite element limit analysis
Finite element limit analysis (FELA) is a numerical method combining finite elements with plasticity limit theorems to compute rigorous bounds on the collapse loads of soils and structures.
Finite element method
The finite element method (FEM), also known as finite element analysis, is a numerical technique that solves partial differential equations by subdividing a domain into simple finite elements.
Finite element method in structural mechanics
The finite element method in structural mechanics is a numerical technique for solving elasticity equations by dividing a structure into small elements and assembling their equations.
Finite element model
A finite element model is a numerical representation of a physical structure or system, discretized into elements connected at nodes, built to predict stress, deformation, heat transfer, or fluid behavior.
Finite field
A finite field, also called a Galois field, is a field with a finite number of elements. Its order is always a prime power, and one such field exists for each.
Finite field arithmetic
Finite field arithmetic, also called Galois field arithmetic, is arithmetic in a field with a finite number of elements rather than in infinite fields like the rationals.
Finite geometry
Finite geometry is the branch of geometry that studies geometric structures with finitely many points, notably projective and affine spaces over finite fields, with applications to coding theory and cryptography.
Finite group
A finite group is a group containing only finitely many elements, the count being its order. Finite groups model symmetries of finite objects and arise throughout mathematics and physics.
Finite impulse response
A finite impulse response (FIR) filter is a digital filter that computes each output as a weighted sum of current and past input samples, with no feedback.
Finite integration technique
The finite integration technique (FIT) is a numerical method for computational electromagnetics, proposed by Thomas Weiland in 1977, that discretizes Maxwell's equations in integral form on dual interlaced grids.
Finite model property
The finite model property (FMP) is a property of a logic: every satisfiable formula has a finite model, giving a standard route to proving decidability in modal logic.
Finite model theory
Finite model theory is the branch of mathematical logic studying the expressive power of logical languages over finite structures, with applications in databases, complexity theory, and formal languages.
Finite potential well
The finite potential well, also called the finite square well, is a quantum mechanics model problem whose finite-depth walls confine a particle with finitely many bound levels.
Finite set
A finite set is a set whose elements can be counted with a natural number n; the number n is the set's cardinality, and any set that is not finite is infinite.
Finite strip method
The finite strip method (FSM) is a semi-analytical numerical technique for analyzing prismatic structures like folded plates and bridge decks, first applied by Y. K. Cheung in the late 1960s.
Finite verb
Finite verb: a verb form marked for tense, person, and number that heads an independent clause; from Latin finitus. Contrasted with non-finite forms (infinitives, gerunds, participles); English modals and bare forms complicate the marking.
Finite volume method
The finite volume method (FVM) is a numerical technique that solves partial differential equations by enforcing integral conservation laws over a mesh of control volumes.
Finite-difference time-domain method
The finite-difference time-domain (FDTD) method, also known as Yee's method, is a numerical technique for solving Maxwell's equations, introduced by Kane S. Yee in 1966.
Finite-key security analysis in quantum key distribution
Finite-key security analysis is the branch of quantum key distribution security theory that proves secrecy of keys from finite signal blocks, quantifying how statistical fluctuations reduce extractable key length.
