This talk is intended to provide an overview of the phenomena of superconductivity and superfluidity. Starting with the fundamental criteria based on which the superconducting materials are characterized, a composite theoretical picture will be discussed which captures the essential physics of a plethora of superconducting systems, viz. the BCS-BEC crossover. Going beyond the stringent material parameter constraints of the solid state systems, the advent of the ultracold atomic gases have provided us with an unprecedented possibility of engineering exotic superfluid states. In this talk the speaker would touch upon some of those possibilities.
