He related α to the Eddington number, which was his estimate of the number of protons in the universe. This led him in … See more The most precise value of α (obtained experimentally in 2012) is: $${\displaystyle \alpha ^{-1}=137.035\,999\,174(35).}$$ Consequently, no … See more • John D.

During the 1920s until his death, Eddington increasingly concentrated on what he called "fundamental theory" which was intended to be a unification of quantum theory, relativity, cosmology, and gravitation. At first he progressed along "traditional" lines, but turned increasingly to an almost numerological analysis of the dimensionless ratios of fundamental constants. His basic approach was to combine several fundamental constants in order to produce a dimen…
