Weber–Fechner law — The Weber–Fechner law attempts to describe the relationship between the physical magnitudes of stimuli and the perceived intensity of the stimuli. Ernst Heinrich Weber (1795–1878) was one of the first people to approach the study of the human… … Wikipedia
Anger function — In mathematics, the Anger function, introduced in harv|Anger|1855, is a function defined by: mathbf{J} u(z)=frac{1}{pi} int 0^pi cos ( u heta zsin heta) ,d heta.and is closely related to Bessel functions.The Weber function, introduced by… … Wikipedia

Confluent hypergeometric function — In mathematics, a confluent hypergeometric function is a solution of a confluent hypergeometric equation, which is a degenerate form of a hypergeometric differential equation where two of the three regular singularities merge into an irregular… … Wikipedia
Lommel function — The Lommel differential equation is an inhomogeneous form of the Bessel differential equation:z^2 frac{d^2y}{dz^2} + z frac{dy}{dz} + (z^2 u^2)y = z^{mu+1}.Two solutions are given by the Lommel functions s mu;, nu;( z ) and S mu;, nu;( z ),… … Wikipedia
Bessel function — In mathematics, Bessel functions, first defined by the mathematician Daniel Bernoulli and generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel s differential equation: for an arbitrary real or complex number α (the order of the … Wikipedia
Robert Weber (astronomer) — Robert Weber was an American astronomer who ran the precursor to the LINEAR project shortly before his retirement in 1996. Data were collected by manually entering telescope pointing positions and requesting an image save. Searching twenty fields … Wikipedia
Ghirardi-Rimini-Weber theory — The Ghirardi Rimini Weber theory, or GRW, is a collapse theory in quantum mechanics. GRW differs from other collapse theories by proposing that wave function collapse happens spontaneously. GRW is an attempt to avoid the measurement problem in… … Wikipedia
Parabolic cylinder function — In mathematics, the parabolic cylinder functions are special functions defined as solutions to the differential equation:frac{d^2f}{dz^2} + left(az^2+bz+c ight)f=0.This equation is found, for example, when the technique of separation of variables … Wikipedia
