Requiring little more than calculus and some linear algebra, this book provides readers with a coherent path to understanding relativity. It helps readers learn just enough differential geometry to grasp the basics of general relativity. The first half of the book describes

Describes rotations in three dimensions and in various symmetry groups. This title offers an introduction to the properties of the octonions, with emphasis on their geometric structure. It includes applications such as: the exceptional Lie groups, octonionic projective spaces, and applications to particle physics.

Requiring little more than calculus and some linear algebra, this book provides readers with a coherent path to understanding relativity. It helps readers learn just enough differential geometry to grasp the basics of general relativity. The first half of the book describes some of the surprising implications of relativity without introducing more formalism than necessary. The second half takes a more detailed look at the mathematics of differential forms, showing how they are used to describe key geometric ideas in general relativity.
