Listing the currently accepted definitions of information would
be nice. The list should at least include the ones used in
math/computer science: Fisher information, Shannon/Renyi information
(which is quite different from the Fisher information), etc...:
e.g. look to the Wikipedia site.
But information concepts are needed in other areas and
all definitions may be criticized since none of them is
suitable in all areas.
