Today it appears in the context of the search for a unified theory of the fundamental interactions. It touches both fundamental and applied physics, as the postulated unalterability of the constants is the foundation for modern metrology. The book presents reviews written by leading experts in the field. Focussing on the question of variations of the fundamental "constants" in time or space, the chapters cover the theoretical framework in which variations are expected and the search for variations of quantities such as the fine-structure constant, the electron/proton mass ratio, g-factors of proton and neutron etc. in astrophysical and geophysical observations and in precision experiments with atomic clocks and frequency standards. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v648 606 $aPhysical constants$vCongresses 606 $aMetrology$vCongresses 606 $aMeasurement$vCongresses 606 $aAstrophysics$vCongresses 615 0$aPhysical constants 615 0$aMetrology 615 0$aMeasurement 615 0$aAstrophysics 676 $a530.81 702 $aPeik$b E$g(Ekkehard), 702 $aKarshenboim$b S.
