ABSTRACT: This talk will review the most important aspects of the phenomenon of superconductivity, discuss the surprising materials in which superconductivity has been found in the past few years, and survey some real and potential applications of superconductors. Some time will be spent on measurements we make at OSU of the "super-electron" (or, superfluid) density, whose magnitude and temperature dependence are sensitive probes of the superconducting quantum state, e.g., the symmetry of the superconducting energy gap and the relative influence of long-wavelength thermal and quantum fluctuations as opposed to single-particle excitations.
