Geometric refers to the 3-Dimensional space in which we live, and to the structures and algebras which describe 3D geometry.
3D geometry necessarily includes Points, Lines, Areas, and Volumes; and 4 non-coplanar Points are required to determine a Volume.

Here, we utilize the 4-level Grassmann geometric algebra,
with basis elements of { 3 Vectors, 1 Point }, here denoted G 3 p 1 .
This 16-element algebra reveals subtle relations among vectors,
particularly relating to push/pull vs twist, and to move vs circulate/spin.

Under development is a new expression and visualization of the "Maxwell" field equations for particles with Charge and Spin.

Local refers to all dynamic effects being local to each particle at that time, precluding instantaneous "action-at-a-distance."

Causal means arising from explicit dynamical effects, rather than from "probability wavefunctions", although in practice limited knowledge may require averaging over unknown variables. One explicit characterization of probability is:
"There is no such thing as a physical probability".

2-Sided means that energy exchange is most properly viewed as symmetric transfer between 2 bound particles, rather than from 1 particle into a field, or from 1 particle into a "fixed" background energy Hamiltonian.
With constant "speed of causality c ", two interacting particles will experience "equal and opposite" forces simultaneously.

This Web-Site is a "work in progress", bringing together insights from 40 years of plama physics experimentation and theory development, emphasizing simple "visualization". It is hoped that some of these insights will help clarify the subtle aspects of electro-magnetism.
