Chapter 2: Space and Time in Special Relativity
Special relativity, along with quantum mechanics, is considered a cornerstone of modern physics. In fact, the combination of special relativity and quantum mechanics yields relativistic quantum mechanics. While this book is not a book on relativistic quantum mechanics,1 the knowledge of basic relativity is important for the understanding of quantum mechanics.
