From the "This attractive book provides an account of the theory of special relativity from a geometrical viewpoint, explaining the unification and insights that are given by such a treatment. […] Can be read with profit by all who have taken a first course in relativity physics." ASLIB Book Guide
This book give a deep dive into relativistic physics, it introduced me to the ideas of invariants and how it can be invariant in a 4-dimension space time coordinates
