- An Introduction to the Lorentz-Dirac Equation - Notes by Eric Poisson providing two derivations of the Lorentz--Dirac equation.
- Relativistic quantum mechanics - An electronic textbook for relativistic quantum mechanics is presented. It can be ordered free
- Selected Papers on Geometric Algebra in Quantum Mechanics - These papers analyze the quantum mechanical Dirac theory of the electron with respect to its geometric structure as revealed by reformulation in terms of Spacetime Algebra
- The Quantum Theory of Particles - A new approach to relativity, quantum mechanics, and field theory which solves many old puzzles, such as ultraviolet infinities and superluminal spreading of wave packets.
