Abstract
The London penetration depth plays a key role in determining and uncovering many properties of a superconductor, including homogeneity, anisotropy, isotope effects, importance of quantum and thermal fluctuations, and facets of the nature of superconductivity in a particular material. Guided by the generic phase diagram in the temperature-dopant concentration plane we examine experimental data on the temperature, isotope substitution, inhomogeneity and magnetic field dependence of the penetration depths to uncover some facets of the mystery of superconductivity in the cuprates
