[.ca] Introduction to Spacetime: A First Course on Relativity (ISBN 9810219296)

Fine modern advanced undergraduate special relativity:
This material of this book was successfully used in a course of special relativity for advanced undergraduates at the University of Stockholm by the late professor Bertel Laurent, one of Oskar Klein's best students. When he sadly passed away shortly before retirement the manuscript was transformed into a book by his enthusiastic friend Stig Flodmark. The book is unusual in that it does not discuss the historical, philosophical, and experimental background that most book dwell on a lot. Instead special relativity is clearly and simply presented with modern coordinate free (index free) notation as a correct and accepted theory of physics. I recommend it strongly as a concise, pedagogical, and compact course book with a modern point of view.
