Sorry Loet, but I just don't see the need for an observer. I do think the difference must be by something to something (perhaps the same thing) but Koichiro's formulation implies this. Again, I warn against unneeded complication. Sent from Samsung Mobile OK. Let's get rid of Koichiro's observer. Remains the need to specify: 1. The first difference; 2. The second difference; The first difference can be measured using Shannon-type information, since a probability distribution can be considered as a set of (first-order) differences. Brillouin tried to specify the second difference as a ΔH. ΔH can also be negative ("negentropy"). But how does one proceed to the measurement? Best, Loet PS. I apologize to Pedro if this is beyond my second posting. I'll shut up. I needed to correct the misunderstanding as if the observer would be important to me. L.
