The Physical Origins of Partial Differential Equations,ke most mathematical models, Maxwell’s equations are based on experiment and physical observations. In general, a mathematical model is a simplified description of physical reality expressed in mathematical terms. Mathematical modeling involves physical observation, selection of the relevant physica

Mathematical equations have always provided a context in which to formulate concepts in physics- Maxwell’s equations describe electrodynamical phenomena, Newton’s equations describe mechanical systems, Schr?dinger’s equation describes aspects of quantum mechanics

Partial Differential Equations on Unbounded Domains, boundaries. We begin with the heat equation, or diffusion equation, on the real line. That is, we consider the initial value problem .Physically, this problem is a model of heat flow in an infinitely long bar where the initial temperature . is prescribed. Notice that there are no boundaries in the

Partial Differential Equations on Bounded Domains, is to assume that the unknown function u = u(χ, .) (we assume that the independent variables are χ and .) in an initial boundary value problem can be written as a product of a function of χ and a function of ., that is, .. Thus, the variables separate. If the method is to be successful, when this p
