This book presents the latest developments in world physics, including chapters on the regularisation and numerical solution of direct and inverse waveguide problems; the predictability and unpredictability from the perspective of the interpretations of quantum mechanics; the external gamma radiation dose in Mexico; the quantum formulation of the electromagnetic field and London's theory; the wide-aperture CO2 lasers pumped by electron-beam-controlled discharge; periodic surface structure induced on dental enamel by CO2 laser 10.6 μm radiation; and the influence of the supernova explosion in M1 on the long-range order in water of agarose hydrogel, on domains in proteins and on the human bio field.
