Hello Sung and Arturo. Entropy is a measure of disorder and ΔS > 0. If entropy is zero at T = 0 K because there is no disorder at T = absolute zero then entropy can only increase from T = 0 K. If that is the case how can entropy ever be negative? Arturo asked me to share a private email I sent

Hi Arturo, I agree. Engtropy can be negative MATHEMATICALLY, as Shroedinger assumed. But what I am claiming is that that may be a mathematical artifact, since, according to the Third Law of Thermodynamics, therer is no negative entropy. All the best. Sung

Dear Sung, I'm sorry, but the "Unreasonable Effectiveness of Mathematics" still holds true.  Forget philosophical concepts like Yin and Yang, because, in some cases and contexts , entropy is negative.  Just to make an example, "Since the entropy H(S|O) can now become negative, erasing a

Hi Arturo, (1) I don't understand where you got (or how you can justify) S = 1 J/K in your statement, "With the same probability mass function, you can see that H = S/(ln(2)*kB), so setting S = 1J/K gives a Shannon entropy of 1.045×1023 bits." (2) I can see how one can get H =

Hi FISers, The following statement cannot be true. "a proposal: information might stand for free energy." Fore one thing, the unit of information is bits and that of energy is cal or erg. The proper relation between information and energy (including free energy) may be complementarity, just
