Short Theory of Special Relativity and Invariant Formulation of Electrodynamics

Werner Herr


The basic concepts of special relativity are presented in this paper. Consequences for the design and operation of particle accelerators are discussed, along with applications. Although all branches of physics must fulfil the principles of special relativity, the focus of this paper is the application to electro-magnetism. The formulation of physics laws in the form of four-vectors allows a fully invariant formulation of electromagnetic theory and a reformulation of Maxwell’s equations. This significantly simplifies the treatment of moving charges in electromagnetic fields and can explain some open questions.
