I wrote in my last book how I suspect others have evolved as well. What is needed is a good dimensional analysis. Unfortunately, dimensional analysis seems foreign to physicists. Otherwise, they wouldn't be making some of the incredible claims that are abroad! :) Cheers, Bob Quoting Stanley N Salthe ssal...@binghamton.edu: Gordana has said: Information and Energy/Matter What can we hope for from studies of information related to energy/matter (as it appears for us in space/time)?

Hi Pedro,
happy Xmas and New Year!

Step Six of Learn to
Count in Twelve Easy StepsWhat happened
previously: Step 1.:We have introduced
additional describing aspects of the logical sentence a+b=c. Next to a,b,c, we
also make use of u=b-a, k=b-2a, t=2b-3a, q=a-2b, s=17-(a+b|c), w=2a-3b.Step
2.:We have introduced the
collection of additions we shall use. We have generated the aspects
{a,b,c,k,u,t,q,s,w} of the 136 smallest pairs of a,b. Step 3.:We have shown
that a sort
on the data set – with any of the aspects as first, a different aspect as the
second sorting argument – assigns a place to an addition; different sorts may
assign different places.Step 4.:Ordering the data set on
all pairs of aspects brings forth 72 variants of realisations of the order
principle based on {|=|}. Some of the sorting orders are identical,
some contradictory. The contradictions are visible on
{place|amount|frequency|order}. The task is to consolidate the
contradictions.Step 5.:Those sorting orders which
to each addition assign identical sequential numbers build a common “clan”
together. In the version of the Table presented here, 20 clans are visible.
Members of a clan can differ on their number of teeth; the place of an element
within a tie is not quite indeterminable but is rather dependent of how finely
has the preceding sorting order had sorted previously.Step
6.:Reordering:After having eliminated the
easy cases, where no reordering is needed, we now confront the mechanics of
transforming the sequence alphabeta into the sequence gammadelta. (V[alfabeta,
gammadelta]=.f.) This procedure is called “reordering” and as its effect, an
element j that previously had the sequential place p1 has now the
sequential place p2. (p1 {=|#} p2)Of specific interest is the
case, wherein during a reorder, several elements have to move together in the
course of a reordering. This is the main concept of the Twelve
Steps.Explaining the main
concept: The central concept can be
pointed out exactly, by deictic methods. Before doing so, let us try to
explicate the idea in colloquial speech. One knows from everyday life that a
change of places may be an intricate business, as oftentimes someone has to
vacate first the place in which a different person will come to sit, while the
person expelled has to ask a 3rd one to liberate his place in turn,
etc. This can get quite complicated, but normally people don’t talk much about
it, as it normally has a solution that is evident to all. Rubik’s cube shows
a specific instance of the
central concept at work. (Please see 6.graph.Rubik). The concept presented
here
is similar to that made visible in the cube, but for the following points:
there, 6 planes are given and 24 elements move while 6 are fixed; the task is
deducting from the known results of the planes the collection and the sequence
of the repetitive procedures (“operations”) that will result in the goal being
achieved. Here, we have 136 elements, none of them fixed and the number of
planes can be a subject of a spirited debate. The task here is to deduct the
appearance of the planes after having gone thru all repetitive procedures
(“operations”). In the case of the cube, the pleasure of having solved the
puzzle encounters one as soon as one understands the procedures of which the
resulting planes are an implication; here, success comes from having
understood
the planes that result from the applications of the procedures.In logistics
one
would speak of “merchandise in transit”, where one will use effective and
expected matches between material and spatial references.Names for the main
concept:Wittgenstein calls the idea
discussed here a Sachverhalt (pls see around 2.01 in
http://people.umass.edu/phil335-klement-2/tlp/tlp.html#bodytext).
It appears ok to interpret, that the Sachverhalt is that “amount j is on
place p”, while the Zusammenhang is that “j moves together within
{j,j’,j’’,...etc} during a reorder from alphabeta into gammadelta”.
Heraclit has predicted the
dynamic interdependence among realisations of the order without giving a
specific name to it. He points out the “upward-downward path”
(http://en.wikipedia.org/wiki/Heraclitus#Panta_rhei.2C_.22everything_flows.22).
Here, we may make use of
the ideas – and the names – of the connotations of a convoy, chain, string or
rhythm for the Zusammenhang and step or tact for the Sachverhalt.Data:The
deictic definition is
done by presenting a fragment of Table T (please see 6.num). Each line in
Table
T is one step in the process of reordering. We
