Maybe this will help you with the Kripke thing:
Personally, I don't get into the minutia of modal logic, I just look at
the over all picture...

Umm, this looks to say that the equivalence is under multiplication by
a scalar? Like the face on a balloon, it remains a face under arbitrary
size changes that do not rupture the balloon...

Umm, one key difference between fermions and bosons is compressibility.
Since compressibility is a key property of information, I do see a

Really, Photons are defined as null rays connecting "source and sink".
I have a thought, a visual. Can we think of the "lateral" distance
between the null rays as the distance between the points on a surface
that the null ray "penetrates". We can think of a light-cone as defined
by a ballon-like surface that "blows" up from a single point such that
the points on the surface maintain their relations. But there are
several properties that puzzle me: (a) There exist an infinite number of
points that can act as sources. (b) The relationships that occur on the
surface would exist in some way "on the point". (c) Surfaces can
interpenetrate, e.g. superpose, without interaction.
I am thinking of information as being defined on the relations on the
surfaces, so by (a) there exist an infinite number of different
information structure. Also, by (b), I think of the "meaning" of the
information in terms of a graph (nodes and edges connecting them). This
is illustrates by thinking of a dictionary and considering word entries
as nodes and the "definition" as the adjoined nodes, e.g. the nodes that
that word has edges to. By (c), I see that the graphs can "share" nodes,
but not edges.
Is this making sense? What I am really interested is what happens when
we consider the dual of the graphs, e.g. change nodes to edges and edges
to nodes! Note that nodes do not have "directedness" but edges can! This
looks like what happens in a supersymmetry transform of Bosons <->
Fermions! Photons are "self-dual" in their spin direction but fermions

Yes, I agree! I see the discussion of Fisher Information by Frieden as
an attempt to get into the details of this! :-)

I see a more direct link between mind and QM! Let us look at how the
"truth" value of proposition can be defined for QM. Pratt says that in
QM truth values have complex numerical values! What does that mean? Each
mind is defined in terms of "what-ifs" (to use your excellent term) that
connect a given set of stimuli and a given set of behaviors. The usual
computational formalism for this is in terms of "input-output" pairs.
(BTW, there is something weird about how to order complex numbers...)
To relate this to the earlier notion of a ballooning surface; what acts
to connect the points on the surface to each other?

Very neat! So is unity achieved asymptotically in the infinite limit,
Lim i -> \inf. : x = 0 ? I am having a hard time with the math. :-(

Ok, but what does that imply for distributions of velocities, e.g. Can
we think of worlds in terms of different NOW/PAST pairs?

Umm, this is very interesting. I would like to understand your thinking
