The Pauli Exclusion Principle from Quaternion Algebra
A Derivation Without Spin Statistics
The anti-commutativity of quaternion multiplication — ij = −ji — means two identical fermions exchanging positions produce a wavefunction that is its own negative. Exclusion is not a postulate; it is quaternion arithmetic.
Atomic Transitions and Spectral Lines from Quaternion Geometry
The “quantum leap” emerges as a rotation on the quaternion 3-sphere rather than a mysterious discontinuity. Discrete energy levels and the Rydberg formula follow from the algebra’s rotational symmetries — no adjustable parameters.
The weak interaction read as curvature of the quaternion phase — a ladder of visibility thresholds from the 23.4 keV atom to the 80.4 GeV weak bubble, with chemistry running at the temperature of its own curvature.
Scattering, Spin, and the Electron from Algebra Alone
Scattering cross-sections, the electron’s magnetic moment, and pair-creation threshold energy — all derived from the geometry of the unit quaternion sphere and octonion multiplication alone, with no prior physical theory.
