Serhii Stepanov: Relativistic World / Mechanics

In contrast to other introductions to special relativity, this one aims at a conceptually clear presentation of the theory. While not shying away from the proper mathematics, an emphasis is placed on an easy understanding of the underlying concepts, rather than technical calulcations only. With an entertaining writing style, comic-like illustrations and instructive problems, this textbook makes the entry to special relativity a lot easier.
