Eh? Physics guys loudly accept that entropy can go up locally. They
just  say universal ( meaning at the scale of the universe ) entropy
is what goes up. Sagan at one point assigned values to the relative 
entropy/order increases from reading something, for example.

Penrose/Hawking and everybody else since have used
communications theory quite a bit to do physics. I
don't even think it's settled yet.

Penroses' "Emperor's New Mind" misses quite a bit ( he
skyhooks some stuff ) but that alone should show they're
thinking about it.

If physics has a problem, it is that the experiments have all gotten
too expensive for a 1920s-1950s level of progress to occur. That, and
string  theory becoming too precious and abstract.
