A robust thermodynamic argument shows that a small reduction of the effective coupling constant α of QED greatly enhances the low-energy Compton-scattering cross section and that the Thomson scattering length is connected to a fundamental scale λ. A discussion provides a possible quantum interpretation of this enormous sensitivity to changes in the effective coupling constant α.
