Twenty-three of the fundamental physical constants, including the Planck constant, Coulomb constant and the gravitational constant (G), are derived by wave equations based on four, new fundamental constants: wave speed, wavelength, amplitude and

Physical Constants (a major revision) Table 1.1. Revised 2019 by C.G. Wohl (LBNL). Reviewed by P.J. Mohr and D.B. Newell (NIST). Mainly from “CODATA Recommended Values of the Fundamental Physical Constants: 2018,” E. Tiesinga, D.B. Newell, P.J. Mohr, and B.N. Taylor, NIST SP961 (May 2019).
The ten dimensionless universal constants to be used here have already been listed at the beginning of §1.1. In this chapter we describe what these constants are. The set of universal constants adopted depends upon the most fundamental physical theory considered. Our ambitions are modest.
