• Sommario/riassunto: Divergencies in quantum field theory referred to as "infinite zero-point energy" have been a problem for 70 years. Renormalization has always been considered an unsatisfactory remedy. In 1985 it was found that Maxwell's equations generally do not have solutions that satisfy the causality law. An additional term for magnetic dipole currents corrected this shortcoming. Rotating magnetic dipoles produce magnetic dipole currents, just as rotating electric dipoles in a material like barium titanate produce electric dipole currents. Electric dipole currents were always part of Maxwell's equations.

• Sommario/riassunto: The book focuses on the situation of Brittany coastal fishing in the early 2000s. It addresses the question of regulated access to fishing resources. It examines the exploitation of main stocks and the characteristics of the fishing fleet. The economic efficiency of vessels is analysed, including the impact of increased fuel costs at the beginning of the decade. Fishing for pleasure is investigated through the results of a national survey which highlights the characteristics of yachtsmen enjoying this leisure activity in Brittany.
