# 4: Pauli Algebra and Electrodynamics


• 4.1: Lorentz transformation and Lorentz force
• 4.2: The Free Maxwell Field
Our approach to CED thus far is unusual inasmuch as we have effectively defined, classified and transformed the electromagnetic field at a small region of space-time without having used the Maxwell equations. This is, of course, an indication of the effectiveness of our definition of the field in terms of active Lorentz transformations.
