Introduction to special relativity is a classic text established for use in undergraduate and postgraduate Physics courses. The content has a coherence of its own and can be used in multiple ways. It can form part of an introductory Physics course to build upon the background in electromagnetism and Optics or used in a modern Physics course for developing foundations of relativity. In addition, it offers optional material of intrinsic interest as supplementary topics and other material of historical, advanced, or special nature as part of Chapter text. Worked-out examples, thought-provoking questions and problems of varied levels of difficulty are the useful pedagogical aids.
