The Theory of Fields

Fields play a fundamental role in the modern formulation of fundamental interactions. We introduce the basic equation of motion for fields, and discuss their most important solutions: The wave solution is relevant both for electromagnetic radiation and for the description of a beam of particles within the framework of quantum field theory. The Coulomb solution describes fields around point-like bodies. The existence of a wave solution for the gravitational field leads to the prediction of the existence of gravitational waves. These are being searched for in experiments being carried out today; the design of these experiments is sketched.
