# The fundamental constants and their variation: observational and theoretical status

@article{Uzan2003TheFC, title={The fundamental constants and their variation: observational and theoretical status}, author={Jean-Philippe Uzan}, journal={Reviews of Modern Physics}, year={2003}, volume={75}, pages={403-455} }

This article describes the various experimental bounds on the variation of the fundamental constants of nature. After a discussion of the role of fundamental constants, their definition and link with metrology, it reviews the various constraints on the variation of the fine-structure constant, the gravitational, weak- and strong-interaction couplings and the electron-to-proton mass ratio. The review aims (1) to provide the basics of each measurement, (2) to show as clearly as possible why it…
