1One well–known example is black–body radiation. According to the classical theory, the radiation density per unit frequency grows proportionally to , a function whose integral over , from zero to infinity, diverges (“the ultraviolet catastrophe”). This absurd is resolved by quantum mechanical considerations, according to which the factor kT should be replaced by , which is close to kT at low frequencies, but decays exponentially for .
