Abstract
We present and discuss two exact, but perhaps unfamiliar, representations of thermal radiation. The first has the form of a superposition of the quantum vacuum and a stochastic classical field and the second is the pure-state thermofield representation introduced by Takahashi and Umezawa. It is interesting that the former is, essentially, the opposite of Planck’s original conception of blackbody radiation.
