BIPM Symposium: The Fundamental Constants of Physics

The fundamental constants of physics:
What are they and what is their role in redefining the SI?

    This symposium is organized by the Consultative Committee for Units (CCU) to celebrate the work accomplished towards a redefinition of the SI in terms of invariant physical constants.

    The main topics of the discussion will be: the profound nature of the different fundamental physical constants; the different types of fundamental constants as well as their role in the evolution of physical theory, in particular in gravitation, cosmology and in string theory. The role of the fundamental constants in the forthcoming definition of the SI will be examined.

    The Symposium aims at promoting scientific exchange amongst the National Metrology Institutes and leading scientists in the field of fundamental constants.
