The ability of inflation to homogenize the universe also means that it leaves the cosmos at effectively zero temperature. Any successful theory of inflation must also explain how the cosmos was reheated to the high temperatures. One of the key realization of the past few years has been that the process of reheating can have a profound impact on the cosmological predictions. In this talk we will review the basic scenarios for particle production by an oscillating scalar field by parametric resonance.
