The Butterfly Effect
The "Butterfly Effect" is the propensity of a system to be sensitive to initial conditions.Such systems over time become unpredictable,this idea gave rise to the notion of a butterfly flapping it's wings in one area of the world,causing a tornado or some such weather event to occur in another remote area of the world.
Where do these ideas of weather exist, before they find themselves funneling into man's framework, called the brain?
It was Socrates' turn to look puzzled.
"Oh, wake up. You know what chaos is. Simple deterministic dynamics leading to irregular, random-looking behavior. Butterfly effect. That stuff."
Of course, I know that," Socrates said in irritation. "No, it was the idea of dynamic logic that was puzzling me. How can logic be dynamic
In contemplating the essence of the ideas of complexity it became increasingly clear to me, that the ideas manifesting and philosophies that were looking at this, could be recognized in tell tale signs of international terrorism of the worst kind.
The final image of the twin towers in panel shown, before, such a contemplative action, spoke to such complexities. Had we been able to see what effect this action had, we might have then said look, indeed, where is it's origination. The reveberations, "symbolically," not only shook the foundation, but was started long before and continue to this day.
Whether the state of the nation or of the world community, such attempts to disrupt, left signatures with it's ideological thinking, that became the trademark of expansive and multple effects, as if, reverberating from a initial idea. Community and science spoke freely. Had we let evil loose, from such conceptualizations?
This raises a much deeper and fundamental question then, about the nature of reality that would emerge in this Third Superstring Revolution, that such conceptualization are now open and free. That questions of self organization, had fundamental thoughts governing it's growth all along.
These ideas always existed then, in the bulk, but waited, for the right channel to express themselves? Like beget's like, and manifests into form?
You see?
Plato as a City Slicker
You all know the saying of this one thing, right?
The rest of the Republic answers this challenge. It does so by way of an analogy. Socrates says that it is difficult to distinguish what is going on in the soul, but it is easier to see what is going on in the state. Thus the state will be examined by analogy to the soul. Now we would say that the state is the macrocosm (makros, "large," kosmos, "universe"), the large scale analogue, and the soul is the microcosm (mikros, "small"), the small scale analogue. When matters are sorted out for the state, then the soul can be understood in its own right.
Well wisdom is bestowed upon us all, when we consider this one thing. Is it the stuff all dreams are made up of?
Hooft, Witten and now Lauglin himself understands, that we have come face to face with a problem? By arguing "stuff", would we have divested ourselves of recognition of this Third Superstring Revolution? Of course not.:)
So instead of defining the state of the cosmo and the insignificance of the microscopic views of man's soulful journey, what value had we'd be lured in too, but by Curlies Pot of Gold?
The Republic: "You must contrive for your future rulers another and a better life than that of a ruler, and then you may have a well-ordered State; for only in the State which offers this, will they rule who are truly rich, not in silver and gold, but in virtue and wisdom, which are the true blessings of life."
I don't think so. The expansive nature of the cosmo is still very relevant to the expansiveness yet to be contained with our humble brains? Some cannot leave the four-square of earth, and wonder about the shape, representing God, yet the diversity of opinion reocgnizes that a view has formed, of a world so few recognize.

Chaotic Competition
It was always easy to focus on two points and what separate them? Quark to Quark measure, defined someway and it was not to hard to see that the space became important within those measures that we understood what this energy meant.
The emergent property, pointed us to reconsider the one dimension value to say that the mass indication could have been looking at how this formation resolved itself, that we might have called it harmonical in value?
INstead of pool balls or drunk sargeant majors, we learnt to see the concepts in another way.
Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across the surface. But we also hear the click of sound as they impact: that’s collision energy being radiated into a third dimension above and beyond the surface. In this picture, the billiard balls are like protons and neutrons, and the sound wave behaves like the graviton.
There was Light
Maxwell's equations are also about half an inch long. For example, Maxwell's equations say that the "four-dimensional divergence of an antisymmetric, second-rank tensor equals zero." That's Maxwell's equations, the equations for light. And in fact, at Berkeley, you can buy a T-shirt which says, "In the beginning, God said the four-dimensional divergence of an antisymmetric, second rank tensor equals zero, and there was Light, and it was good."
A lot of times it is not easy to "focus" on other then, legitmate toy models of Feynman? Anything arising from the Planck Epoch had to be understood as it arose through to cosmic expression?
If you do not follow this history, you will never understand what Nima Arkani-Hamed, Sava Dimopoulos, and Gia Dvali been doing with extra dimensions. There is a conceptual feature here that I have spoken too in regards to gravity that few understand.

A Quantum-Mechanical Discription of Gravity
I do not know how much more generalized these views could have become from those who now look to what the physicists and theoreticians are doing in their questions for explaining the nature of the reality we are encountering.
If few recognize it, then it is showing us strong signals of what is to come. Some will leap ahead?
"Nothing to me would be more poetic; no outcome would be more graceful ... than for us to confirm our theories of the ultramicroscopic makeup of spacetime and matter by turning our giant telescopes skyward and gazing at the stars," Greene said.
The Elegant Universe, by Brian Greene, pg 231 and Pg 232
"But now, almost a century after Einstein's tour-de-force, string theory gives us a quantum-mechanical discription of gravity that, by necessity, modifies general relativity when distances involved become as short as the Planck length. Since Reinmannian geometry is the mathetical core of genral relativity, this means that it too must be modified in order to reflect faithfully the new short distance physics of string theory. Whereas general relativity asserts that the curved properties of the universe are described by Reinmannian geometry, string theory asserts this is true only if we examine the fabric of the universe on large enough scales. On scales as small as planck length a new kind of geometry must emerge, one that aligns with the new physics of string theory. This new geometry is called, quantum geometry."
There are two obvious routes to quantum gravity. The first, and most beaten path so far, is to formulate general relativity into a quantum field theory in which the gravitational force is carried by the exchange of gravitons. The problem is that gravitons carry mass and energy, which are the source of the gravitational field in the first place. This leads to infinities that render calculations meaningless.
Amelino-Camelia points to Glast determinations in regards to LQG, yet there is a deepr sense of what can be revealled?

New Non-geometrical Generalization of the Principles of CFT Found?
There is always a certain expectancy, when it comes having formulated the theoretical work, that further developement along these lines presenst the opportunities for such things to exist.
A new non-geometrical generalization of the principles of CFT will be found, and it will allow to extend the success of S-matrices etc. to the non-perturbative realm. A geometry-like original of dualities - such as E_k in supergravity - will be clarified. Non-perturbative physics on general backgrounds will become calculable, and supersymmetry breaking will be shown to be very different in details than previously anticipated. Realistic N=1 4D vacua with SUSY breaking will be connected and the potential will pick up a rather small number of priviliged points - close to the "heterotic strings on Calabi-Yau three-folds" and/or "M-theory on G2 manifolds" and/or "intersecting brane models with some warping". Two years after the beginning of the revolution, the people will calculate the masses of the heaviest quarks, the (small) QCD theta-angle, and other things, and they will predict the first new physics beyond the SM, which will be only confirmed several years later experimentally.
Meanwhile, the structure of M-theory in 11D will be solved exactly, and the position of poles of the scattering amplitudes in 11D will be known more or less exactly.
Alternatively, theorists won't be that fast, and the revolution will start experimentally in 2007, most likely with the LHC. A rather simple pattern of masses of superpartners will be found, together with supersymmetry, and it will match one of the popular SUSY scenarios within string theory. Alternatively, small black holes or excited strings are gonna be seen, and their precise patterns will be used to reversely engineer the shape of branes and hidden dimensions.

Self-Organization of Matter
Everyone knows that human societies organize themselves. But it is also true that nature organizes itself, and that the principles by which it does this is what modern science, and especially modern physics, is all about. The purpose of my talk today is to explain this idea.
So why is it so difficult to accept the idea that if a Professor is walking across the room, that many of his students would congregate.:) Just as they would in any other attempts at defining the nature of this reality?
Hooft, Witten and now Lauglin himself understands, that we have face to face with a problem? By arguing "stuff", would we have divested ourselves of recognition of this Third Superstring Revolution? Of course not.:)
Likewise, if the very fabric of the Universe is in a quantum-critical state, then the "stuff" that underlies reality is totally irrelevant-it could be anything, says Laughlin. Even if the string theorists show that strings can give rise to the matter and natural laws we know, they won't have proved that strings are the answer-merely one of the infinite number of possible answers. It could as well be pool balls or Lego bricks or drunk sergeant majors.
Witten's statement has then brought myself to recognize strings will manifest as a emergent property of spacetime. It is a conceptual reocgnition, that does not falter under the guise of irrelevant possibilties, but one facet of a concerted effort.
Are Strings as Spacetime an Emergent Phenomena?
One thing I can tell you, though, is that most string theorist's suspect that spacetime is a emergent Phenomena in the language of condensed matter physics.
Above Witten asks a legitmate question, and so does Gerard t'Hooft as shown in previous links. How would you change computerization to handle these new perceptions of previous experimental processes?
I have watched this gentlemen/woman develope this site(below) over the years and the the exchange of information from other forums. I learnt to appreciate the perspective that were forming.
There was a radical change in my perceptions, that to me ask that we reconsider the discription of all that we had learnt in regards to quantum mechanics, so that we look at the way we had develope concepts and experimental processes under this new language. It did not say, do away with all experimental processes, but asked us to look at them in another way?
Beyond String Theory
The Greek Pythagoras, for instance, was able to use abstract but simple mathematics to describe a natural phenomenon very precisely. He discovered the fractions that govern the harmonious musical notes. For example, a stretched string on a violin that produces a C note when you strike it, will give a C an octave higher when you divide its length by two. (Similarly, when we cut of a quarter of the length of the original srting, the new string will sound like an E note) This is a famous early example of the use of mathematics to describe a physical phenomenon accurately. Pythagoras used the mathematics of fractions to describe the frequency of musical notes. In the ages that followed, of Galilei, Kepler, Newton and Einstein, mathematics became the prime language to depict nature. The mathematics of numbers, sets, functions, surfaces etcetera turned out to be the most useful tool for those people that felt the urge to understand the laws governing nature.

Longitudinal and Transverse Information about the Energy Deposition Pattern
The calorimeter design for GLAST produces flashes of light that are used to determine how much energy is in each gamma-ray. A calorimeter ("calorie-meter") is a device that measures the energy (heat: calor) of a particle when it is totally absorbed. CsI(Tl) bars, arranged in a segmented manner, give both longitudinal and transverse information about the energy deposition pattern. Once a gamma ray penetrates through the anticoincidence shield, the silicon-strip tracker and lead converter planes, it then passes into the cesium-iodide calorimeters. This causes a scintillation reaction in the cesium-iodide, and the resultant light flash is photoelectrically converted to a voltage. This voltage is then digitized, recorded and relayed to earth by the spacecraft's onboard computer and telemetry antenna. Cesium-iodide blocks are arranged in two perpendicular directions, to provide additional positional information about the shower.
I am enamoured by the ideas of Nature, that such sublteness could have been defined in the cosmo with this exchange of information. That we are now looking at these events in the cosmo with some understanding, using measurements, where previously held comments about what we had understood in that same cosmo, had not shown to be of any use?
For the well informed, and those who venture into the Blog of Petter Woit, we find, that even Sean Carrol must caution Peter and thus I do the same, here, not just in regards to supersymmetry( my previous posts in early historical journey laid out in the question of Gerard t'Hooft), the ways in which interpret and map these dynamical situations?
A question is left in my mind as Gerard postulates that same universe. How would the fundamentals of quantum mechanics speak to what we had understood here.
Without some guidance and tutorial thoughts for introspection one would have to wonder about the artistic interpretation we assign the energy of this dynamical universe?

The Looking Glast
To test the claim, Gninenko has proposed a new experiment at CERN. He and his colleagues would confine orthopositronium to a sensitive heat-measuring device, called a calorimeter. The device would be under a strict vacuum to isolate its contents from collisions with other matter, which could confound the findings. Under ordinary conditions, the orthopositronium constituents—an electron and a positron—produce a specific amount of energy when they annihilate each other. But that energy simply wouldn't be there if the orthopositronium had oscillated into its undetectable mirror form.
