General property of information

Do you agree to the following:

1. sign of information: information is non-negative (the minimum is zero). It is always positive in value.
2. objectivity of information: information is not subjective, it does not depend on observer or
observer's mood; the value is the same if the observer drank a lot of beer in Basel because
Basel and Swiss football team played very well these days). In a precise scientific word,
information is a state function or function of the structure.
3. energy and information: it related to some kind of energy by temperature. Temperature can be
either negative or positive (I studied temperature concept quite carefully).
What kind of energy is it? I guess it is potential energy.
4. information loss is entropy (N. Lewis' definition).

Some less clear property:
6. additivity and extensivity hold only for independent (non interactive)
subsystems and independent symbols. E.g., two copies of
completely different books in one bag, one is Shakesperea's, the other is Sch�dinger's "What is Life".
However, non-additivity for subsystems of certain relations:
total information of two subsystems assembled are equal or
less than the sum of the information values of their individual subsystems
(It cannot be used as an evidence against objectivity of information). example:
If Pedro and Shu-Kun put two copies of Sch�dinger's "What is Life" in one bag.
the information in the bag is only that of one copy of "What is Life".
7. information of the universe goes towards zero (This one is not really
clear because I cannot prove it).

Any more items to be added? Any comments?

(I drank a lot of beer. Do not take it serious. Gggoood Nnnight!!).
