A classical spinor approach to the quantum/classical interface

A promising approach to the quantum/classical interface is described. It is based on a formulation of relativistic classical mechanics in the Clifford algebra of physical space. Spinors and projectors arise naturally and provide powerful tools for solving problems in classical electrodynamics. They also reproduce many quantum results, allowing insight into quantum processes.PACS Nos.: 03.65.Ca, 03.65.Ta, 04.20.Gz, 02.10.Xm
