This textbook combines the mathematical foundations of the theory of special and general relativity with numerous applications in physics and astronomy. Besides the discussion of classical experiments that impressively confirm the predictions of the theory of relativity, a special focus is on cosmology, as an important application of general relativity. The discussion of the physics of compact stellar objects, i.e. white dwarfs, neutron stars, and black holes, and a short section on the formation and evolution of stars complement the presentation.The authors put special emphasis on relativistic visualization. Two chapters give an overview of various visualization techniques in special and general relativity. Examples of relativistic visualization make the predictions of relativity, which so blatantly seem to contradict everyday experience, more tangible and intelligible. The resulting figures and accompanying videos support the understanding of the topics covered in the text. The videos are accessible also via the Springer Nature More Media App.This edition is the translation and extension of a textbook of the authors written in German. It also includes more recent developments in astrophysics and cosmology, such as the detection and observation of gravitational waves, or the Hubble controversy.The book is intended for students of physics and related study courses who would like to get an overview of both the theory of relativity and its areas of application. However, the interested layperson, too, will gain a new and deeper insight into relativity and astrophysics.

In this book we summarize the essential results of our efforts over the years to calculate energies, wave functions, and electromagnetic transitions of atoms as functions of the magnetic field strength from laboratory fields up to neutron star magnetic fields. Motivated by the observational evidence of huge magnetic 5 fields with strengths up to 10 T in the vicinity of white dwarf stars and of up 9 to 10 T in the vicinity of neutron stars the authors, together with coworkers and candidates for doctor and diploma degrees, have investigated this ,fasci­ nating quantum mechanical problem more or less continuously since 1978. The extensive tables and figures in the appendices represent the most complete data set to date in this field of research. For practical use all numbers are available by "anonymous ftp" over Internet. The first direct measurement of a neutron star magnetic field by Trum­ per and his group, who observed a cyclotron feature at about 50 ke V in the spectrum of the X-ray pulsar Hercules X-I corresponding to a field strength of 8 several 10 T, stimulated investigations of atoms within the framework of the adiabatic approximation, which is well justified for such field strengths. This method and its results are discussed in Chaps. 3, 5, and 6.
