Chapter 20: The Electron Mass Prediction

Part II culminates in the first quantitative prediction of the τ³ framework: the proton-to-electron mass ratio. Three ingredients—breathing modes on T², the Epstein zeta function of the torus lattice, and the holonomy correction π³α²—combine into a single formula with no free parameters: equation* R_0 = ι_τ^{-7} - √3 ι_τ^{-2}. equation* With ι_τ = 2/(π + e) ≈ 0.341304, this gives R₀ ≈ 1838.7, in striking agreement with the CODATA value m_n/m_e = 1838.684….
