Evgenii, I am not sure if it is your text, or Russell's":
*"**In general, I do not understand what does it mean that information
at zero Kelvin is zero. Let us take a coin and cool it down. Do you mean
that the text on the coin will disappear? Or you mean that no one device
can read this text at zero Kelvin?"*
I doubt that the "text" embossed on a coin is "its" *information*. It is
part of the "physical" structure as e.g. the roundness. size, or
material(?) characteristics - all, what nobody can imagine how to change
for the condition of 0-Kelvin. The abs. zero temp. conditions are
extrapolated the best way we could muster. A matter of (sci.) faith. Maybe
the so called 'interstitial' spaces also collapse? I am not for a
'physicalistic' worldview - rather an agnostic about 'explanations' of
diverse epochs based on then recent 'findings' (mostly mathematically
realizing that we may be up to lots of novelties we have no idea about
today, not even of the directions they may shove our views into. I say that
in comparison to our 'conventional scientific' - even everyday's - views of
the world in the past, before and after fundamental knowledge-domains were
added to our inventory.
I do not condone evidences "that must be, because THERE IS NO OTHER WAY" -
in our existing ignorance of course. Atoms? well, if there *is* 'matter'?
(MASS??) even my (macro)molecules I invented are suspect.
So 'entropy' is a nice term in (classical?) thermodynamics what I coined in
1942 as *"the science that tells us how things would proceed wouldn't they
proceed as they do indeed"* thinking of Carnot and the isotherm/reversible
equilibria, etc. - way before the irreversible kind was taught in college
courses. Information is another rather difficult term, I like to use
'relation' and leave it open what so far unknown relations may affect our
processes we assign to 'causes' known within the model of the world we
think we are in. The rest (including our misunderstood model - domain) is
what I may call an 'infinite complexity' of which we are part - mostly
ignorant about the 'beyond model' everything.
We 'fabricate' our context, try to explain by the portion we know of - as
if it was the totality - and live in our happy conventional scientific
Human ingenuity constructed a miraculous science and technology that is
ALMOST good (some mistakes notwithstanding occurring), then comes M. Curie,
Watson-Crick, Fleming, Copernicus, Volta, etc. and we re-write the
