The Author David T.C. Porthouse

did a Ph.D. in computational fluid dynamics in the Department of Mechanical Engineering, University of Newcastle upon Tyne. He used the method of two-dimensional point-vortices to model the flow around a stalling aerofoil. The aerofoil was analysed by the Martensen Method. The vortices all convect each other as they separate, and viscosity is modelled by Brownian motion of vorticity, as originally proposed by A.J. Chorin (1). Look at the computer programs KHI.BAS and KARMAN.BAS on this website to get an idea of what this is all about.

Modelling of Brownian motion requires the use of a random number generator, and it is as plain as day that we should be asking if something similar can be done for quantum mechanics. This is the theme of this website.

The author, as a fluid dynamicist turned quantum mechanic, is still learning about quantum mechanics as he goes along. A number-crunching job on any big system of differential equations, Navier-Stokes or Dirac-Maxwell, is no problem. Something extra is required for quantum mechanics, however. What is it?
