In 1937 the query of a potential temporal version of the basic constants was once raised via Paul Dirac in his "large quantity hypothesis." this present day it seems that within the context of the hunt for a unified concept of the elemental interactions. It touches either basic and utilized physics, because the postulated unalterability of the constants is the root for contemporary metrology. The e-book offers stories written by way of major specialists within the box. Focussing at the query of adaptations of the elemental "constants" in time or house, the chapters disguise the theoretical framework during which diversifications are anticipated and the quest for adaptations of amounts comparable to the fine-structure consistent, the electron/proton mass ratio, g-factors of proton and neutron and so forth. in astrophysical and geophysical observations and in precision experiments with atomic clocks and frequency standards.
