Possible variations of the fine structure constant and their metrological significance
We briefly review the recent experimental results on possible variations of
the fine structure constant on the cosmological time scale and its
position dependence. We outline the theoretical grounds for the assumption that
might be variable, mention some phenomenological models incorporating
a variable into the context of modern cosmology and discuss the
significance of possible variations for theoretical and practical
metrology.Comment: Latex, 17 pages, brief review. References updated, minor errors
