Relativistic Inversion, Invariance and Inter-Action

A general formula for inversion in a relativistic Clifford–Dirac algebra has been derived. Identifying the base elements of as those space and time, first order differential equations over all quantities proves to encompass Maxwell equations, leads natural extension incorporating rest mass spin, allows an integration with quantum mechanics. Although is not division algebra, it parallels reality well: where undefined turns out correspond physical limits, such that light cone. The divisor corresponds invariants dynamical significance, invariant interval, electromagnetism, basis set Dirac equation. It speculated apparent 3-dimensionality nature arises from beautiful symmetry between three-vector each four sets three derived spaces full 4-dimensional algebra. conjectured may play role interaction fields matter.
