Special Relativity: A Heuristic Approach

Special Relativity: A Heuristic Approach is an intermediate textbook on relativity, unique both in its approach and its content. The book approaches relativity with the Lorentz Transformations, which are the key to understanding the subject. Once they are derived as coordinate transformations that leave the distance in the two-dimensional spacetime unchanged and later generalized to four dimensions, the Lorentz transformations are applied to a multitude of examples (many unique to this book) to illustrate their power and immunity from mistakes that other approaches may entail (as demonstrated in Problem 7.1). The content of the book is also unique. Whereas topics such as interstellar travel and relativistic photography are either completely ignored or only mentioned on passing in one or two paragraphs in other textbooks, this book devotes two complete chapters to these topics The interstellar travel is in particular timely because of the interest in projects such as Breakthrough Starshot, which aims to send "nanocrafts" to Alpha Centauri. Other topics unique to the book are an accessible discussion of the Dirac equation and the discovery of antimatter, as well as an easy-to-understand introduction to the big bang and early universe. Key Features, Provides a heuristic derivation of the Minkowskian distance formula after deriving the Euclidean distance formula for the flatlanders. Emphasizes Lorentz transformations as the key to understanding special relativity ad provides countless examples (some appearing for the first time) of their use. Provides a reader-friendly introduction to tensor algebra and how it is used in special relativity. Features two complete chapters devoted to interstellar travel and relativistic photography. Written in a very accessible style. All derivations are worked out and explained in detail. A companion website provides a complete Solutions Manual for close to three hundred end-of-chapter problems.
