This book offers an essential bridge between college-level introductions
and advanced graduate-level books on special relativity.
It begins at an elementary level, presenting and discussing the basic
concepts normally covered in college-level works, including the Lorentz
transformation. Subsequent chapters introduce the four-dimensional
worldview implied by the Lorentz transformations, mixing time and space
coordinates, before continuing on to the formalism of tensors, a topic
usually avoided in lower-level courses. The book's second half addresses
a number of essential points, including the concept of causality; the
equivalence between mass and energy, including applications;
relativistic optics; and measurements and matter in Minkowski
space-time. The closing chapters focus on the energy-momentum tensor of
a continuous distribution of mass-energy and its co-variant
conservation; angular momentum; a discussion of the scalar field of
perfect fluids and the Maxwell field; and general coordinates.
Every chapter is supplemented by a section with numerous exercises,
allowing readers to practice the theory. These exercises constitute an
essential part of the textbook, and the solutions to approximately half
of them are provided in the appendix.
