The Standard Model calculation of g-2 requires thousands of Feynman diagrams. This geometric model derives it from the topology of the lepton (icosahedron, 12 vertices). It posits the muon anomaly is the sum of the surface cost (Schwinger term) and the nodal friction against the 12 vertices: α = 0.00729735256
N_v = 12
Schwinger_term = α / (2 · π)
Nodal_term = α^2 / 12
a_mu = Schwinger_term + Nodal_term
Schwinger_term = α / (2 · π) ≈ 0.001161409
Nodal_term = α^2 / 12 ≈ 0.000004438
Total ≈ 0.001165847
Experimental value: 0.001165920
Discrepancy: 63 ppm
