Abstract: Stochastic Resonance is a phenomenon where the ability of a system to detect weak signals can improve as the environmental noise level increases. This effect is now firmly established in a wide variety of physical and, more recently, biological systems. I will give a broad introduction to the subject, starting with its beginnings as an explanation of the periodic occurrence of ice ages on Earth, up to recent ideas how stochastic resonance might be usefully exploited.
