which is about
a fresh view of entropy. Since I am an engineering student
(i.e., familair with
Carnot heat engine but not other definition of entropy such
as Shannon's ), any
body would like to talk more about the article? | b*o

发帖数: 47 | 3 I always feel that the engineer definition of entropy is
awkward.
This one seems better to me. By the way, has the school of
Prigogine
founs anything exciting about irreversible thermodynamics? | f*******d
发帖数: 339 | 4 That is a propaganda article of their approach to
thermodynamics (so called axiomatic approach).
The mainstream view of thermodynamics among physicists is
that thermodynamics
should be derived from statistical physics, and the entropy
in stat mech.
is defined as S=k N log N, where N is the number of
microscopic states,
Shannon generalized the concept of microscopic state to
possible
states in communication, thus derived a similar formula for
"information".
Lieb and Yngvason take another point of
