101Neumann boundary condition — In mathematics, the Neumann (or second type) boundary condition is a type of boundary condition, named after Carl Neumann.[1] When imposed on an ordinary or a partial differential equation, it specifies the values that the derivative of a… …
102Jacobi integral — In celestial mechanics, Jacobi s integral represents a solution to the circular restricted three body problem of celestial mechanics. [1] The Jacobi integral is the only known integral for the 3 body restricted problem; unlike in the two body… …
103Lorenz gauge condition — In electromagnetism, the Lorenz gauge or Lorenz gauge condition are common misnomers for a particular choice of the electromagnetic four potential A^a. The potential is chosen to satisfy the condition partial aA^a=0, which was first proposed by… …
104Central force — In classical mechanics, a central force is a force whose magnitude only depends on the distance r of the object from the origin and is directed along the line joining them: cite web url= http://scienceworld.wolfram.com/physics/CentralForce.html… …
105Riesz potential — In mathematics, a Riesz potential is a scalar function V {alpha} : mathbb{R}^{n} o mathbb{R}, n geq 2, of the form:V {alpha} (x)= int mathbb{R^n} frac{1}{| x y |^{alpha , mathrm{d} mu (y),where alpha > 0 and mu is a Borel measure whose support is …
106Trisops — was an experimental machine for the study of magnetic confinement of plasmas with the ultimate goal of producing fusion power. The configuration was a variation of a compact toroid, a toroidal (doughnut shaped) structure of plasma and magnetic… …
107Swift-Hohenberg equation — The Swift Hohenberg equation is a partial differential equation noted for its pattern forming behaviour. It takes the form:frac{partial u}{partial t} = r u (1+ abla^2)^2u + N(u)where u = u ( x , t ) or u = u ( x , y , t ) is a scalar function… …
108Ultrahyperbolic wave equation — In the mathematical field of partial differential equations, the ultrahyperbolic wave equation is a partial differential equation for an unknown scalar function u of 2 n variables x 1, ..., x n , y 1, ..., y n of the form: frac{partial^2… …
109sample preparation — ▪ chemistry Introduction in analytical chemistry (chemistry), the processes in which a representative piece of material is extracted from a larger amount and readied for analysis. Sampling and sample preparation have a unique meaning and special …
110determinant — noun a) A determining factor; an element that determines the nature of something b) The unique scalar function over square matrices which is distributive over matrix multiplication, multilinear in the rows and columns, and takes the value of 1… …
