Special Relativity

The general problem of relativistic addition of velocities – and the successive application of noncollinear Lorentz boosts – is addressed.

This is chapter 1 of a book by Chris Doran and Anthony Lasenby on geometric algebra, which is the natural mathematics of spacetime.

There is a preferred algebra of quaternions and complex numbers that is ideally suited to express the equations of special relativity and classical electrodynamics.

Self-tutorial with short essays, questions and answers.
