This Special Relativity undergraduate text is part of the successful SUMS series from Springer. It is designed to introduce 2nd and 3rd year mathematicians to the subject, giving them a firm grounding which, if they wish, will lead onto the more specialised mathematical physics texts. The approach here, unlike many competitive books, is to teach by using examples and exercises, its this user-friendly approach that will appeal to students and lecturers, in courses such as Relativity, Special Relativity, and Mathematical Physics.
