Abstract

Taking into account four universal constants, namely the Planck's constant hh, the velocity of light cc, the constant of gravitation GG and the Boltzmann's constant kk leads to structuring theoretical physics in terms of three theories each taking into account a pair of constants: the quantum theory of fields (hh and cc), the general theory of relativity (cc and GG) and quantum statistics (hh and kk). These three theories are not yet unified but, together, they underlie the standard models that allow a satisfactory phenomenological description of all experimental or observational data, in particle physics and in cosmology and they provide, through the modern interpretation of quantum physics, fundamental metrology with a reliable theoretical basis.
