Fundamental constants in quantum electrodynamics

It has been shown the fine-structure and Rydberg constants, the permeability and permittivity of free space, and electron charge can lead to an improved understanding of physical phenomena. It has been shown complex multidimensional networks of relationships exist among the different physical constants. Utilizing five fundamental constants measured with high accuracy, other constants with similar accuracy can, indirectly, by an appropriate combination of several other constants, be obtained. The indirect value is often more accurate than direct value
