So, that is what we came up with — A few very
simple models, such as the one that involves 3
objects: one
object A producing thermal energy and radiating energy at a fixed rate, two other
objects B and C whose temperature is determined
via radiative balance with
object A and empty space, with a geometry such that the temperature of
object B is higher than that of
object C. And, what we wanted to illustrate is that the
object C «warms» B in the colloquial sense of the word... i.e., that the presence of
object C causes B to be at a higher temperature than if C is absent.
