The first part of this fifth volwne of The Enigmatic Photon consists of three chapters which develop electrodynamics as a gauge field theory with internal 0(3) symmetry using a complex basis ((1), (2), (3)). This is referred to for convenience as 0(3) electrodynamics. The field equations are intrinsically non-linear and non-Abelian, and the classical potential is a physical quantity. The field equations are shown to be self-consistent and a general mathematical basis for the development is given in terms of extended Lie algebra. The third chapter develops radiatively induced fermion resonance (RFR). The opening three chapters are followed by a selection of previously unpublished scientific papers which trace the historical development of 0(3) electrodynamics through the physically observable B(3) field. The editors are greatly indebted to Dr. Laura J. Evans for her painstaking preparation of Part I and Part IT of this volwne. This work included typesetting from original manuscripts and indexing. The production of the five volwnes of this series would not have been possible without her steadfast and generous contributions. Discussions with many colleagues over internet sharpened the ideas behind this volwne. Finally, the organizational support of the Alpha Foundation, founded by Milan Meszaros, proved invaluable during the later preparatory stage~.
