Abstract: This article contains a proposal for a new and simple equation that can be used to calculate the reciprocal electromagnetic (em) fine structure constant α⁻¹ at low energies:
\alpha^{-1}=16\pi
Solving this equation will lead to:
\alpha^{-1}=137.0359992264… .
If the experimental error bar is taken into account, this value in comparison with the newest (2012) experimental value of 137.035999174(35) will show an extremely precise conformity within a relative deviation of 10⁻¹⁰.
An explanation is given of the physical background of the proposed equation, which is based on the masses of the leptons and the W⁺ boson, on quantum electrodynamic (QED) calculations on the vacuum polarization, and on the statement that all coupling constants at the Planck energy
(1.22 10^{19}GeV)
have the value
1/16\pi.
