## Abstract

A non-mathematical account of a theory in which particles are pictured not as points but as spatially extended periodic disturbances in a classical background field - objects which vary in form and size according to the interactions they encounter and which, in particular, abruptly collapse to much smaller disturbances when they are detected. This quasi-classical theory treats the classical and quantum domains on the same fundamental footing. It is shown that, when the particle sizes are small compared with their separations, they must satisfy classical laws such as Newton`s equations of motion and Maxwell`s electrodynamics, but when a particle is close to, or overlaps, the source of interaction its time evolution is given by quantum formulae such as the Schroedinger equation.
