There is this alternative: https://en.wikipedia.org/wiki/David_McGoveran#Discrete_Physics "In 1988, [David McGoveran developed] methods to develop a new derivation of the Fine Structure Spectrum of Hydrogen, which was further developed and published with H.P. Noyes. In later work, the approach was shown to support Feynman sum-over-paths in 1+1 dimensions and gave the solution to the Dirac equation (Green's function). Noyes has cited McGoveran's calculation of the Sommerfeld-Dirac formula and corrections to both the* combinatorial hierarchy computation of the fine structure and gravitational consta*nts as convincing him that the evolving combinatorial hierarchy construction could be the starting point for a new physics and physical cosmology." - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
