Foundation Mathematics for Computer Science temperature, chemical composition, etc.). If any of these quantities is not uniformly distributed, the system is not in equilibrium and exchanges occur of a mechanical or thermal nature between nearby elements until equilibrium is eventually achieved.

In general, viscosity and thermal conduction are also of little importance in interstellar gas. Consider the role of thermal conduction in a molecular cloud of size ., with temperature . and density ..

Foundation Mathematics for Computer Science electrons and on the ions producing currents. In turn currents cause alterations in the electro-magnetic field: hence, we have to do with a complicated coupled system of matter and fields. We focus on conductor fluids, that is, on ionised gases. The fundamental difference between a non-conducting g

Foundation Mathematics for Engineers the magnetic tension tends to bring them back into rectilinear form, however causing transverse oscillations. This type of magnetohydrodynamic wave, called Alfven wave, is the only one possible in an incompressible fluid. If we assume infinite electrical conductivity, the magnetic lines of force ar
