As some of us have being trying to point out for years now, "heat" does not
"flow". This phenomenon is not so counterintuitive if that fact is
remembered.

Again if we want to understand new phenomena, we should stop using caloric
thinking: "heat" is not a substance which is "transferred". Resist
correct thinking if you will, but you risk missing some of the
physics. This is a case in point.
