I am disappointed that both John D and Mike take it as given, that
the energy flux is inextricably tied to the overt change of state.
I suspect that Connie Tyree is closer to the mark, with a covert
structural alignment accounting for the energy flux.

 Just cos it don't agree with the standard story, doesn't mean
 it's wrong....    :-)

And she's DONE the experiment!
