That is, rather than describing the world by saying where each particle is, we describe it in terms of how loops are knotted and linked with one another. This approach to quantum theory was invented by another friend — Carlo Rovelli — and myself, and also by the very interesting Uruguayan physicist Rodolfo Gambini.

The main result of this work
is that at the
Planck
scale, which is twenty powers of ten smaller than an atomic nucleus, space
looks like a
network
or weave of discrete loops. In fact, these loops are something like the
atoms out of which space is built. We're able to predict that — just as
the possible energies an atom can have come in discrete units — when one
probes the structure of space at this Planck scale, one finds that the
possible values the area of a surface or the volume of some region can
have also come in discrete units. What seems to be the smooth geometry
of space at our scale is just the result of an enormous number of these
elementary loops joined and woven together, as an apparently smooth piece
of cloth is really made out of many individual threads.
Furthermore, what's wonderful
about the loop picture is that it's entirely a picture in terms of relations.
There's no preexisting geometry for space, no fixed reference points; everything
is dynamic and relational. This is the way
Einstein
taught us we have to understand the geometry of space and
time
— as something relational and dynamic, not fixed or given a priori. Using
this loop picture, we've been able to translate this idea into the
quantum
theory.
- Lee Smolin
feedback and iteration = self awareness
does this apply to electronic
dance
music?
...the Godelian strange loop
that arises in formal systems in mathematics (i.e., collections of rules
for churning out an endless series of mathematical truths solely by mechanical
symbol-shunting without any regard to meanings or ideas hidden in the shapes
being manipulated) is a loop that allows such a system to "
perceive
itself", to talk about itself, to become "self-aware", and in a sense it
would not be going too far to say that by virtue of having such a loop,
a formal system ACQUIRES A SELF."
[...]
...an "I' comes about - in
my view, at least - via a kind of
vortex
whereby patterns in a brain miror the brain's mirroring of the world, and
eventually mirror themselves, whereupon the vortex of "I" becomes
real,
causal entity. For an imperfect but vivid concrete analogue to this
curious abstract phenomenon, think of what happens when a TV camera is
pointed at a TV screen so as to display the screen on itself (and that
screen on itself, etc.) - what in GEB I called a "self-engulfing television",
and in my later writings I sometimes call a "level-crossing
feedback
loop."
When and only when such a loop arises in a brain or in any other substrate, is a PERSOn - a unique new "I" - brought into being. Moreover, the more self-referentially rich such a loop is, the more conscious is the self to which it gives rise. Yes, shocking thought this might sound, consciousness is not an on/off phenomenon, but admits of degrees, grades, shades.

Escher,
