Semi-Classical Electrodynamics and the Casimir Effect

Abstract

From the late 1960s and onwards the groups of Barry Ninham and Adrian Parsegian, and their many collaborators, made a number of important contributions to theory and experiment of intermolecular forces. In particular, they explored the semi-classical theory: Maxwell's equations and Planck quantization of light $\rightarrow$ Lifshitz and Casimir interactions. We discuss some selected thought-provoking results from Ninham and his group. Some of the results have been conceived as controversial but, we dare, say never uninteresting.
