Re: [Phys-L] let's define energy




Entropy is especially worthwhile because its applications
reach far beyond classical thermo to include communications,
crypto, learning theory, etc. etc. etc.


Is interesting to think entropy as "energy disperssion", and not for
example mass disperssion, or another stuff dispersing. So Shannon entropy
is not the same as thermo entropy, you must account bits energy for that.

Even in the disperssion of salt in water what we call entropy is the
"chemical energy" dispersion, without that T * entropy_change will not
equal heat_exchange

I am not really shure if there is a better methapore about this.
